The BD437S is an NPN bipolar junction transistor manufactured by ON Semiconductor. It has a maximum collector-emitter breakdown voltage of 45V and a maximum collector current of 4A. The device can dissipate up to 36W of power and has a transition frequency of 3MHz. The minimum DC current gain (hFE) is 30 at 10mA collector current and 5V collector-emitter voltage. The collector-emitter saturation voltage is typically 600mV at 200mA base current and 2A collector current.
The transistor is designed for through-hole mounting and is available in a TO-225AA / TO-126-3 package. The supplier device package is TO-126-3. It operates with a maximum junction temperature of 150°C. Per existing data, the BD437S is RoHS3 compliant, REACH unaffected, and has an MSL of 1 (unlimited).
This transistor is suitable for general-purpose switching and amplifier applications, including power management, audio amplification, and motor control circuits. Its robust current and voltage ratings make it a versatile component for various electronic designs.
