NPN General Purpose Transistor 45V 500mA TO-92
Stock Quantity: 0
The BC337-TO92, manufactured by Siemens, is a silicon NPN bipolar junction transistor (BJT) housed in a through-hole TO-92 package. Characterized as a general-purpose amplifier and switching transistor, the “02+” marking indicates a specific hFE (DC current gain) grouping. This signifies a gain within a defined range, typically between 100 and 250 at a collector current of 10 mA and a collector-emitter voltage of 5V, though precise values should be verified with the original Siemens datasheet. The BC337 features a collector-emitter voltage (VCEO) rating of 45V, a collector current (IC) rating of 800mA, and a power dissipation (PD) of approximately 625mW. Its transition frequency (fT) is typically around 100MHz, making it suitable for applications up to the VHF range. The device utilizes a standard B-C-E pinout configuration when viewed from the flat face.
