650V IGBTs Boost Efficiency in 20kHz Power-Switching Applications
The new M-series 650V IGBTs from STMicroelectronics is suitable to increase the efficiency of HVAC motor drives, uninterruptible power supplies, solar power converters, and all power-conversion applications working up to 20kHz in hard-switching circuit topologies.
Built using ST's third generation of trench-gate field-stop low-loss technology, the M-series IGBTs feature a new trench gate and a specially designed P-N-P vertical structure that together deliver the best trade-off between conduction and switch-off losses and significantly improve the overall performance of the devices. A short-circuit withstand time of 6µs minimum at 150°C starting junction temperature, the extended maximum operating junction temperature of 175°C, and a wide Safe Operating Area (SOA) extend service lifetime and boost reliability in applications where high power dissipation is required.
Furthermore, the devices are available in packages that include a new generation of free-wheeling diodes optimized for fast recovery whilst maintaining a low forward drop and a high level of softness. This provides excellent EMI protection while reducing switch-on losses. The positive VCE(sat) temperature coefficient, together with tight parameter distribution, enables the devices to be safely paralleled for even higher power requirements.
Key features of the M series include:
- 650V operation, compared to 600V for most competitive devices
- Low VCE(sat) (1.55V @25°C) to minimize conduction losses
- Large SOA and latch-free operation
- 175°C maximum operating junction temperature
- 6µs of minimum short-circuit withstand capability at high temperature
- Very limited voltage overshoot and no oscillation during switch-off.
Complementing ST's HB series of 650V IGBTs for higher-frequency industrial applications (up to 60 kHz), the M series announced today are available in 10A and 30A current ratings in a selection of power packages including the TO-220, D2PAK, and TO-247 LL long-lead. All devices are in full production, with pricing starting at $1.0 for the 10A STGP10M65DF2 in a TO-220 package for orders of 1000 pieces.
