Product details
Overview
AUIRGDC0250AKMA1 from Infineon Technologies is an automotive-grade 1200 V, 81 A (TC = 100°C) planar IGBT in Super-TO-220 package, optimized for soft-switching PTC heater and relay replacement applications. It delivers 1.47 V typical VCE(on) at 33 A, 150°C-rated junction temperature, and features square RBSOA with 99 A clamped inductive load current capability.
For engineers reviewing the AUIRGDC0250AKMA1 datasheet, AUIRGDC0250AKMA1 pinout, AUIRGDC0250AKMA1 application, or AUIRGDC0250AKMA1 equivalent, key selection criteria include its 0.23 °C/W RθJC, ±20 V gate voltage rating, 151 nC total gate charge, rugged 1200 V VCES, and automotive qualification per AEC-Q101.
Technical Context
This IGBT employs planar technology with positive VCE(on) temperature coefficient and 100% ILM-tested ruggedness for reliable operation under repetitive clamped inductive loads. Its square RBSOA supports stable parallel operation up to 99 A at 960 V with 5 Ω gate resistance and +20 V gate drive.
Designed for high-efficiency soft-switching topologies, it achieves low conduction loss (1.47 V @ 33 A, 25°C) and controlled switching energy (15 mJ Eoff @ 33 A, 600 V, 25°C), with thermal performance validated under board-mounted, still-air conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage IGBT applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IKW40N120H3 | 1200 V, 40 A, TO-247 package; lower current rating but higher fSW suitability due to lower Qg (110 nC) | Better suited for 50–100 kHz resonant converters where peak current < 40 A | Select when switching frequency > 40 kHz and thermal envelope permits smaller die size |
| IRGP50B60PD1 | 600 V, 50 A, TO-247; lower voltage rating but higher IC (50 A @ 100°C) and faster tf (100 ns) | Targeted at 400 V industrial inverters-not suitable for 800–1200 V EV architectures | Choose only for legacy 600 V systems requiring higher pulse current and faster switching |
Compared with IKW40N120H3 and IRGP50B60PD1, AUIRGDC0250AKMA1 uniquely balances 1200 V blocking, 81 A continuous current, and automotive qualification-making it the sole option for AEC-Q101-compliant 1200 V PTC heater and auxiliary relay applications.

FAQ
What is the maximum gate-emitter voltage rating for AUIRGDC0250AKMA1?
The AUIRGDC0250AKMA1 supports ±20 V continuous gate-to-emitter voltage and ±30 V transient rating. Exceeding ±20 V continuously risks gate oxide degradation; gate drivers must include clamping or active regulation to maintain safe operation within this limit across temperature and lifetime.
Does AUIRGDC0250AKMA1 require a negative gate voltage for turn-off?
No. The device operates with 0 V to +15 V gate drive for normal switching; negative gate bias is not required. However, applying –5 V to –10 V during off-state improves noise immunity and prevents spurious turn-on in high-dV/dt environments such as traction inverters.
Can AUIRGDC0250AKMA1 be paralleled with identical units?
Yes-its positive VCE(on) temperature coefficient and square RBSOA enable stable current sharing. Successful parallel operation requires matched gate drive impedance (< ±5% variation), symmetrical PCB layout, and shared heatsink with uniform thermal interface pressure across all devices.
What is the thermal resistance from junction to case (RθJC) for AUIRGDC0250AKMA1?
The maximum RθJC is 0.23 °C/W, measured at ~90°C junction temperature under board-mounted, still-air conditions. This value assumes full contact between the isolated tab and a flat, greased heatsink surface-actual system RθJC may increase by up to 0.05 °C/W if mounting torque or thermal paste application deviates from specification.
