SCRs - Modules datasheet and documents for VHFD29-14IO1

VHFD29-14IO1

SCRs - Modules Overview

The IXYS VHFD29-14IO1 is a half-controlled single-phase rectifier bridge module featuring integrated freewheeling and field diodes. It provides a rated repetitive reverse voltage (VRRM) of 1400 V with a maximum surge peak repetitive reverse voltage (VRSM) of 1500 V. The thyristor leg supports an average forward current (IdAVM) of 32 A at 85°C, while the integrated diode leg handles 4 A. Key electrical parameters include a gate trigger voltage (VGT) of up to 1.2 V, a holding current (IH) of 100 mA, and a typical reverse recovery charge (Qr) of 75 µC for the diode. The unit operates within a junction temperature range of -40°C to +125°C.

SCRs - Modules Procurement Notes

Verify the specific suffix IO1 against official datasheets to confirm pinout compatibility and insulation ratings. Confirm that the 1400V rating aligns with system requirements. Check for RoHS compliance status as indicated in manufacturer documentation. Ensure mounting torque specifications are followed during installation to maintain thermal interface integrity.

SCRs - Modules Selection Notes

Select this component when a compact solution for single-phase rectification with controlled output is required. The integrated freewheeling diode simplifies circuit topology for inductive loads like motors. Consider the 32A thyristor and 4A diode current capabilities relative to the load profile. Evaluate the thermal resistance values against the available heatsinking capacity to ensure junction temperatures remain within safe operating limits.
