BC33740BU Description

Short technical summary and product information.

The BC33740BU is an NPN bipolar junction transistor (BJT) from On Semiconductor, designed for general purpose amplifier and low-speed switching applications. It features a collector-emitter breakdown voltage of 45V, a continuous collector current rating of 800mA, and a power dissipation of 625mW. The DC current gain (hFE) is typically 250 minimum at 100mA collector current with 1V Vce, and the collector-emitter saturation voltage is 700mV maximum at 500mA collector current. The transition frequency is 100MHz, making it suitable for audio frequency amplification and moderate speed switching. The device is housed in a TO-92-3 through-hole package (TO-226-3/TO-92-3), which is widely used for low-power transistors. The operating junction temperature is rated up to 150°C. This transistor is RoHS3 compliant and has an MSL level of 1 (unlimited). It is commonly used in consumer electronics, industrial control, and signal processing circuits.
