5SHY3545L0016
The Nitty-Gritty (Tech Specs)
Here’s the kind of data you actually want when you’re sizing or swapping one of these out:
| Parameter | Value |
|---|---|
| Model | ABB 5SHY3545L0016 |
| Type | High-Power IGBT Module |
| Rated Current | 3600 A |
| Rated Voltage | 4500 V |
| Configuration | Half-bridge |
| Package | Press-pack (hockey puck style) |
| Gate Emitter Voltage | ±20 V |
| Junction Temperature | -40°C to +125°C |
| Typical Application | Medium voltage drives, converters, traction systems |
| Manufacturer | ABB |
These press-pack designs don’t use bond wires like plastic modules — they rely on direct pressure contacts, which means no internal fatigue cracking. That’s a big reason why they last decades in high-cycle service.

Real-World Benefits
The ABB 5SHY3545L0016 enhances power system performance by delivering efficient, high-speed switching that significantly reduces energy losses and thermal load. Its compact design facilitates denser assembly integration, saving valuable space in power electronic modules. The module’s durable construction supports rigorous industrial use, minimizing downtime due to failure and maintenance. Increased switching speed combined with high voltage capability enables improved motor control, renewable energy integration, and power quality management, bringing long-term operational savings and performance reliability.
Typical Use Cases
This IGCT module is extensively used in medium-voltage variable frequency drives, industrial motor control systems, and grid-tied power conversion setups such as wind turbine inverters and traction traction drives. Power plants, heavy industries, and renewable energy projects benefit from its fast and efficient switching characteristics. Its application spans demanding environments that require precise motor speed control, power factor correction, and advanced energy management on medium- to high-voltage scales.
Tales from the Field
I still remember a maintenance shutdown in a hydro plant in Norway where one of these saved us from a week-long outage. A surge from a faulty generator exciter knocked out half the control rack, but when we opened the inverter stack expecting carnage, the 5SHY3545L0016 modules looked pristine. The insulation test checked out, switching behavior was stable — it was the snubber that gave up, not the IGBT. We cleaned it up, swapped the caps, and the plant was spinning again in two days.
That’s when I learned to stop treating ABB’s press-packs as “just another transistor.” They’re practically little mechanical systems in their own right.
Strengths & Real-World Advantages
- Rock-Solid Under Stress: These modules are made for the kind of punishment you get in traction or heavy industry — repeated thermal cycling, voltage spikes, vibration.
- Uniform Pressure Contact: No solder joints to fatigue. Perfect for applications with extreme load fluctuations.
- Thermal Conductivity: The copper base and press-pack assembly make heat dissipation efficient and even.
- Fail-Safe Design: If the device ever fails, it usually shorts safely, which is a lot easier to manage in a high-voltage inverter.
When you’re dealing with a few megawatts of power, “graceful failure” isn’t a luxury — it’s survival.
Installation & Commissioning Tips
- Surface Preparation: The mating surfaces must be spotless. A single speck of dirt can mess up pressure distribution and cause hotspots.
- Torque Accuracy: Always use a calibrated wrench. Too much pressure and you’ll deform the case; too little and you’ll get arc pitting.
- Cooling: These modules love clean, even cooling — use fresh thermal compound and make sure the clamping system’s parallelism is within spec.
- Check Gate Drive Integrity: A poor gate drive or desat circuit can ruin a new module in seconds.
If you’ve ever replaced one in a multi-module stack, you know the drill — it’s like changing the heart of a power converter. One wrong torque spec, and you’re doing it again next week.
The “Watch-Outs”
These things aren’t cheap, and they’re not exactly plug-and-play. You’ll need to make sure your drive firmware and snubber design are matched properly to the 5SHY3545L0016’s switching behavior. I’ve seen guys replace older Westcode parts with this model without retuning the gate drivers — and let’s just say it didn’t end well. Also, they don’t forgive contamination. A bit of oil film or dust on the press surface can change contact resistance enough to cook it.
Where It Shines
You’ll find the ABB 5SHY3545L0016 wherever serious current is moving — medium-voltage drives in mining hoists, ship propulsion systems, traction inverters, and large industrial converters. Basically, any application where downtime costs more than the equipment itself.
The Bottom Line
If you’re building or maintaining a system where reliability under stress matters more than price tags, the ABB 5SHY3545L0016 is the kind of component you want in your power stack. It’s over-engineered in all the right ways, field-proven in every continent I’ve worked on, and stubbornly refuses to quit when everything else gives up.
It’s not glamorous, but in the world of megawatt converters, that’s exactly the kind of personality you want.
