They represent a perfect cost/performance balance and target high efficiency applications switching between 18kHz and 100kHz. Rapid 1 and Rapid 2 are optimized to have excellent compatibility with CoolMOS and high speed IGBT (Insulated Gate Bipolar Transistor) such as the TRENCHSTOP 5 and HighSpeed 3.
