BC337G Description

Short technical summary and product information.

The BC337G is a general-purpose NPN bipolar junction transistor manufactured by ON Semiconductor. It is designed for through-hole mounting in a TO-92 (TO-226-3) package.

With a collector-emitter voltage rating of 45V and a collector current capacity of 800mA, this transistor can handle moderate power levels in a variety of linear and switching applications. The power dissipation is rated at 625mW. DC current gain (hFE) is a minimum of 100 at 100mA collector current and 1V Vce. The saturation voltage is typically 700mV maximum at a drive condition of 50mA base current and 500mA collector current.

The BC337G offers a transition frequency of 210MHz, making it suitable for low-frequency amplification and switching circuits up to a few tens of MHz. The device operates over a junction temperature range of -55°C to 150°C, providing robust performance in demanding environments.

The TO-92 package provides a compact, low-cost solution for through-hole PCB assembly. Typical applications include general-purpose switching, driver stages, and signal amplification in consumer electronics and industrial controls.
