Overview
The 5SHX1445H0002 is an Integrated Gate-Commutated Thyristor (IGCT) module from ABB, available under order numbers 3BHB003386R0101 and 3BHL000387P0101. It merges thyristor-level current capacity with hard-driven transistor-mode turn-off, delivering 4,500 V blocking and 1,445 A average on-state current. This press-pack device suits medium-voltage converter power stacks that demand fast commutation and low conduction loss.
A 0.5 A gate trigger at +15 V DC achieves turn-off in 1 microsecond or less. The module also offers a 2.5 V conduction drop and 0.1 °C/W junction-to-case thermal resistance for continuous high-current operation. In addition, a 10 kA short-circuit withstand rating defines the fault-current limit that gate drive and snubber design must observe.

Gate Drive and Thermal Behavior
The module needs a matched ABB gate driver to deliver the hard turn-off pulse. Because the IGCT works in transistor mode during commutation, gate-unit timing and clamping pressure directly affect switching loss and long-term reliability. Engineers should therefore verify driver compatibility before installation.
Double-sided cooling via pressed heat sinks is assumed. Note that the 0.1 °C/W thermal resistance measures from junction to case, not to ambient. As a result, designers must calculate ambient thermal performance based on their specific heat-sink setup.
Frequently Asked Questions
Q: Are 3BHB003386R0101 and 3BHL000387P0101 different modules?
A: No. Both codes identify the same 5SHX1445H0002 IGCT assembly. Procurement systems may display either number for the same physical device.
Q: Can this module work without a dedicated gate driver?
A: No. The 5SHX1445H0002 requires a compatible ABB gate unit that provides +15 V DC drive and sub-microsecond turn-off control. Using a generic thyristor trigger risks commutation failure.
