TrenchStop IGBT for 600 V power stages — what the ratings actually mean
The IGB30N60TATMA1: TrenchStop gives you a lower saturation voltage than planar IGBTs of the same voltage class, which directly cuts conduction loss in the on-state. Rated for a 175 °C maximum junction temperature, this part handles the thermal cycling of motor drives, welding inverters, and UPS systems where the die sees sustained high current. The 60 A continuous collector rating and 90 A pulsed capability give headroom for inrush and overload events without oversizing the die.
Conduction loss and switching speed — the two numbers that size the heatsink and the gate driver
Vce(on) is specified at 2.05 V typical at 15 V gate drive and 30 A collector current — that is the conduction loss floor at the operating point most designs run. At 60 A the voltage will climb with temperature per the normalised curve, so budget the thermal resistance of the TO-263 tab to the board accordingly.
