Features
Overload capability
TRENCHSTOP™ IGBT7 allows a maximum junction temperature of 175°C where as TRENCHSTOP™ IGBT4 is limited to 150°C. It is beneficial for drives application due to the need of repetitive short overload operation.
By allowing a maximum junction temperature of 175°C TRENCHSTOP™ IGBT7 is optimized for drives applications -
Features
On state voltage
Compared to TRENCHSTOP™ IGBT4, IGBT7 lowers on-state voltage by around 20%. This brings a significant reduction in losses to target applications, especially to industrial drives, which usually operate with moderate switching frequencies.
IGBT7 lowers on-state voltage VCE(sat) and Vf by around 20% -
Features
Controllability
The TRENCHSTOP™ IGBT7 offers a high level of controllability to match the motor insulation requirements or EMI limitations. The controllability corresponds to the device’s ability to vary the dv/dt by adjusting the value of the gate resistor (RG).
Enhanced controllability of dv/dt -
Features
Improved diode
The EC7 emitter-controlled diode reduces the forward voltage by 100 mV relative to the previous generation EC4. This also lowers the reverse recovery losses. In addition, it improves softness, which benefits the inverter’s EMI behavior.
Reduced forward voltage and lower reverse recovery losses

Benefits
Increased power
The EconoDUAL™ 3 with TRENCHSTOP™ IGBT7 can reach up to 900 A. Benefit from higher inverter output current for the same frame size, reduced system cost by avoiding paralleling of modules.
Up to 50 % more power by using the same packages -
Benefits
Frame size jump
An application example for general-purpose drives (GPD) compares modules built with IGBT4 and IGBT7 technologies. This illustrates how power density can be increased while lowering system cost.
Higher power density due to use of smaller power modules -
Benefits
Low losses
The conduction losses at the given dv/dt limitation are significantly decreased. Moreover, there is a reduction in diode losses which leads to overall 15% lower power losses.
Low losses to meet energy efficiency requirements -
Benefits
Optimized driving
CGE and CGC are balanced to give the IGBT7 full control over the dv/dt, and to optimize the switching waveform. CGE is designed to avoid parasitic turn-on effects, zero voltage supply for turn-off is feasible (unipolar gate driver power supply).
IGBT7 is designed for zero voltage turn-off and optimized for simple driving
