Product Introduction
The ABB 5SHX1960L0006 is an OEM IGCT power semiconductor module used in ABB medium-voltage drives, high-power converters, and industrial power conversion systems. The associated part numbers 3BHB016120R0002, 3BHE019719R0101, and GVC736BE101 identify the complete module and matching gate driver assembly.
IGCT devices are selected where high switching speed, high current capability, and low conduction losses are required. Because these modules are used in mission-critical equipment, many plants maintain spare units to reduce downtime after a semiconductor failure.
Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Converter trips with IGCT fault | Failed IGCT module | ✅ High | Read converter diagnostic buffer | Verify semiconductor before replacing control boards |
| Short circuit on DC bus | Internal semiconductor failure | ✅ High | Perform insulation and diode checks with power removed | Replace IGCT if shorted |
| Gate driver fault alarm | GVC736BE101 driver problem | ✅ High | Measure gate drive supply and monitor trigger pulses | Test gate driver before replacing IGCT |
| Excessive heatsink temperature | Cooling system issue | ⚠️ Medium | Inspect fans, coolant flow, and thermal compound | Restore cooling before installing a new module |
| Output phase missing | Open semiconductor or gate trigger loss | ✅ High | Compare phase waveforms with an oscilloscope | Verify both IGCT and driver assembly |
| Immediate fuse failure | External short circuit | ❌ Low | Check motor cables and inverter output | Eliminate external faults before replacing the module |
Service Note
Large IGCT modules are expensive and are often replaced when the actual fault is elsewhere.
Before installing a replacement:
- Verify gate driver output.
- Measure snubber components.
- Inspect busbar insulation.
- Check heatsink flatness and thermal grease coverage.
- Tighten all power terminals to the manufacturer’s specified torque.
A failed cooling fan has destroyed more IGCTs than many technicians realize. Always investigate the root cause before energizing a replacement module.

Frequently Asked Questions (FAQ)
Q1. What is the function of the ABB 5SHX1960L0006?
It is an Integrated Gate-Commutated Thyristor (IGCT) used as the primary switching device in medium-voltage power converters, high-power motor drives, and grid power conversion equipment.
Q2. What do the numbers 3BHB016120R0002, 3BHE019719R0101, and GVC736BE101 represent?
These are ABB assembly and associated component numbers related to the complete IGCT package and its matching gate driver. Many procurement systems reference all four numbers together to ensure the correct replacement is supplied.
Q3. Can I replace only the IGCT without replacing the gate driver?
Sometimes, but not always.
If the gate driver has experienced an overcurrent event or insulation failure, replacing only the semiconductor may lead to another immediate failure. Inspect and test the driver thoroughly before re-energizing the system.
Q4. Is this module hot-swappable?
No.
Never replace an IGCT module with the converter energized. Even after shutdown, the DC-link capacitors may retain hazardous energy. Confirm that all stored energy has been discharged before servicing.
Q5. Why is thermal compound so important?
Poor thermal contact increases junction temperature dramatically. Even a perfectly functioning IGCT can fail prematurely if the heatsink surface is dirty, uneven, or has insufficient thermal interface material.
Q6. Why are New Surplus modules usually less expensive than factory stock?
New Surplus modules are genuine ABB components from excess inventory rather than current production. They have not been installed but are no longer manufactured in large quantities, making them a cost-effective option for maintaining legacy equipment.
Q7. What should I verify before ordering?
Confirm all identification numbers on the existing assembly:
- IGCT Module: 5SHX1960L0006
- Order Number: 3BHB016120R0002
- Associated Board: 3BHE019719R0101
- Gate Driver:
Also verify your converter model, cooling configuration, and gate driver revision to ensure full compatibility.
