STGB3NB60KDT4

Overview

The STGB3NB60KDT4 is a PowerMESH IGBT featuring a 600 V collector-emitter voltage rating and a 3 A continuous collector current capability at 25 °C. It utilizes advanced strip layout technology to achieve low on-state saturation voltage (VCE(sat) < 2 V at 125 °C) and low gate charge. The device includes an integrated antiparallel diode with soft ultra-fast recovery characteristics, making it suitable for high-frequency motor control applications. It offers a short-circuit withstand time of 10 μs and is packaged in a D2PAK tape and reel configuration.

Feature Summary

• PowerMESH technology provides an optimized balance between switching performance and low on-state conduction losses.
• Integrated antiparallel diode features very soft ultra-fast recovery behavior to minimize switching noise.
• Short-circuit rugged design ensures reliable operation under fault conditions with a 10 μs withstand capability.

Applications

• High frequency motor controls
• Switching mode power supplies (SMPS)
• Power factor correction (PFC) circuits

Procurement Notes

Verify the specific ordering suffix 'T4' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the component marking matches the GB3NB60KD identifier found on the datasheet. Ensure the procurement documentation references the correct STMicroelectronics part number to avoid confusion with similar TO-220 or DPAK variants within the same family.

Selection Notes

Select this component when designing resonant or hard-switching topologies requiring high-frequency operation. The low C_res / C_ies ratio helps prevent cross-conduction susceptibility in bridge configurations. Consider the thermal resistance values provided for the D2PAK package to ensure adequate heatsinking for the intended power dissipation levels.

Part Context

This device belongs to the PowerMESH IGBT family developed by STMicroelectronics using patented strip layout technology. The 'K' suffix identifies the series as being specifically optimized for high-frequency motor control applications while maintaining short-circuit withstand capabilities. It complements other variants like the STGP3NB60K which utilize different packaging options such as TO-220.

Replacement Considerations

Direct substitutes include STGP3NB60KD and STGD3NB60KT4, which share identical electrical specifications but differ in physical package type (TO-220FP and DPAK respectively). Verify pinout compatibility and thermal interface requirements before substituting these packages into existing designs.

FAQ
