Additional Details
The SAP15N typically features a collector-emitter voltage (Vceo) of around 230V, a collector current (Ic) of around 15A, and a collector power dissipation (Pc) of around 150W. The current gain (hFE) is typically between 20 and 70, depending on the operating conditions. The operating and storage junction temperature range is -55 to +150 degrees Celsius. The TO-3P package is designed for easy mounting on heat sinks to ensure efficient thermal management, preventing the device from overheating during operation. It is designed to be a complementary pair with SAP15P transistor.
Proper heat sinking is essential to ensure the SAP15N operates within its safe operating area. Consideration should be given to the operating frequency, voltage, and current to prevent exceeding the transistor's maximum ratings.
