STGW15H120DF2

Overview

The STGW15H120DF2 is a single N-channel Insulated Gate Bipolar Transistor (IGBT) from the H series, manufactured by STMicroelectronics. It utilizes an advanced trench gate field-stop structure to optimize the balance between conduction and switching losses. The device features a maximum collector-emitter voltage of 1200 V and a continuous collector current of 15 A at 25°C, with a peak pulsed current capability of 30 A. Key electrical parameters include a saturation voltage of 2.1 V at 15 A, a maximum gate-emitter voltage range of -20 V to +20 V, and a power dissipation rating of 259 W. It operates within a temperature range of -55°C to +175°C and is housed in a TO-247-3 through-hole package.

Feature Summary

• Trench gate field-stop technology for optimized high-frequency efficiency
• Minimized tail current for reduced switching losses
• Slightly positive VCE(sat) temperature coefficient enabling safe paralleling
• Very fast recovery antiparallel diode

Applications

• High-switching frequency converters
• Soft-switching applications
• Induction heating systems

Procurement Notes

Verify component authenticity by checking the manufacturer's marking code against official datasheet specifications. Ensure the TO-247-3 package matches the required footprint and thermal interface. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference the specific suffix DF2 with the intended circuit requirements to ensure functional equivalence.

Selection Notes

Select this component when designing circuits requiring high-speed switching capabilities combined with low conduction losses. The 1200 V rating suits medium-voltage industrial applications. Consider the 15 A continuous current limit and 259 W power dissipation for adequate heatsinking design. The positive temperature coefficient is critical for parallel operation to ensure balanced current sharing among multiple devices.

Part Context

This IGBT belongs to the H series, which is specifically optimized for high-frequency applications. The series aims to maximize converter efficiency by balancing conduction and switching losses. The trench gate field-stop structure distinguishes it from standard planar IGBTs, offering improved performance metrics suitable for modern power electronics designs.

Replacement Considerations

Direct substitutes must match the 1200 V / 15 A rating, TO-247-3 package, and trench gate field-stop technology. Verify that alternative components maintain similar VCE(sat) and switching speed characteristics to ensure circuit compatibility without redesign.
