This is 400V, 1.5A, NPN Silicon Power Transistor. These devices are designed for high-voltage, high-speed power switching inductive circuits where fall time is critical. They are particularly suited for 115 and 220V applications in switch mode.


1. Reverse biased SOA with inductive load @ TC=100°C

2. Inductive switching matrix 0.5 ~ 1.5 Amp, 25 and 100°C Typical tC = 290ns @ 1A, 100°C.

3. 700V blocking capability

Advantages Vs Disadvantages


It is high voltage and current ratings, which make it suitable for use in high-power applications. It also has a fast switching speed, which allows for efficient power conversion.


This is its relatively low collector current rating compared to other power transistors on the market. This may limit its use in some high-power applications.

Additionally, it may require additional circuitry, such as a flyback diode, to protect against voltage spikes during switching.
