The MJ13070 and MJ13071 are NPN silicon power transistors designed for high‑voltage, high‑speed switching in inductive circuits. They are suitable for applications such as switching regulators, inverters, solenoid drivers, motor controls, and deflection circuits.
The document provides maximum ratings, electrical and thermal characteristics, switching times, and safe operating area information, enabling designers to perform worst‑case calculations and select appropriate operating conditions.
