The STGWA50IH65DF is a 650 V, 50 A soft-switching IGBT from the IH series, utilizing a trench gate field-stop structure optimized for resonant and soft-commutation applications. It features a co-packaged freewheeling diode with low forward voltage drop. Key electrical parameters include a collector-emitter saturation voltage of 1.5 V typical at 50 A, a maximum junction temperature of 175 °C, and a total power dissipation of 300 W at 25 °C case temperature. The device operates within a -55 °C to 175 °C junction temperature range.
Verify component authenticity by checking the marking code G50IH65DF against official datasheet specifications. Confirm package type matches TO-247 long leads and ensure compliance with RoHS standards. Cross-reference ordering codes with authorized STMicroelectronics distributors to guarantee product integrity and traceability.
Select this component specifically for soft-switching topologies where minimizing switching losses is critical. Ensure the application circuit supports resonant or zero-voltage switching conditions, as the device is not optimized for hard-switching environments. Verify that the thermal management system can handle the specified power dissipation limits at the intended operating temperatures.
This part belongs to the STPOWER IH series, which focuses on high-efficiency performance in soft-switching circuits. It complements other ST IGBT families like the M series, which targets hard-switching inverters with short-circuit withstand capabilities. The IH series distinguishes itself through optimized conduction and switching loss characteristics tailored for resonant loads.
Direct substitutes within the same family include STGWA40IH65DF and STGWA50HP65FB2, though pinouts and specific electrical ratings may vary. Always verify thermal resistance and package dimensions before substitution to ensure mechanical compatibility.
No, it is designed specifically for soft-commutation only. Using it in hard-switching applications may result in excessive switching losses and reduced efficiency.
The typical VCE(sat) is 1.5 V when measured at IC = 50 A and VGE = 15 V.
Yes, it includes a co-packaged freewheeling diode with a low forward voltage drop to maximize efficiency in resonant applications.
