ABB 5SHX2645L0004 Reverse-Conducting IGCT (RC-IGCT) – 4500 V / 2645 A Press-Pack Power Semiconductor for Medium-Voltage Drives
The ABB 5SHX2645L0004 (ordering codes 3BHL000389P0104 / 3BHB003154R0101) is a reverse-conducting integrated gate-commutated thyristor (RC-IGCT) in a press-pack package. It integrates the GCT thyristor and an anti-parallel freewheeling diode monolithically, and serves as the core power-switching element in ABB’s ACS1000 / ACS5000 / ACS6000 medium-voltage drive inverter and active rectifier stages.
| Parameter | Specification |
|---|---|
| Product Type | Reverse-Conducting IGCT (RC-IGCT), press-pack power semiconductor |
| Ordering / Part Numbers | 5SHX2645L0004; 3BHL000389P0104; 3BHB003154R0101 |
| Repetitive Peak Off-State Voltage (VDRM / VRRM) | 4500 V |
| Controllable Turn-Off Current (ITGQM) | 2645 A; some sources cite nominal / average on-state current as 2600 A or 2645 A depending on the measurement basis (Tc = 85 °C, half-sine wave) |
| Non-Repetitive Surge Current (ITSM) | 6.2 kA (RC-IGCT datasheet basis); alternate catalog figures range from 28 kA to 48 kA (10 ms) across source listings |
| On-State Voltage (VT / VTM) | ≈ 2.8 – 2.9 V at rated current |
| Gate Control | Optical fiber trigger, external gate-drive unit (GDU) required; gate drive voltage typically +20 V / −20 V |
| Cooling Method | Water-cooled / forced air-cooled double-sided pressure cooling |
| Junction Operating Temperature | −40 °C to +125 °C |
| Thermal Resistance (Junction-to-Case) | 0.007 K/W (some listings cite 0.012 °C/W) |
| Package / Clamping | Press-pack ceramic housing; recommended clamping force 25 – 30 kN |
| Weight | Approx. 2.6 – 2.9 kg depending on listing |
| Certifications / Standards | CE; IEC 60747-9 / IEC 61800-5-1 power-electronic standards |
Note on source variance: The 5SHX2645L0004 is consistently identified as an RC-IGCT in ABB medium-voltage drive documentation, but third-party industrial-automation catalogs occasionally list the same numeric identifier under “control module” or “communication unit” categories with low-voltage DC inputs and PLC-style specifications (e.g., 24 V DC, IP20). Those entries reflect unrelated or mismatched catalog listings rather than the ABB power-semiconductor datasheet; the table above prioritizes the RC-IGCT parameter set from power-electronics sources.
