BC857B,235 Description

Short technical summary and product information.

The BC857B,235 is a PNP general-purpose transistor from Nexperia, designed for low-current switching and amplification applications. It features a maximum collector-emitter voltage (VCEO) of -45V and a continuous collector current (IC) of -100mA, with a peak current capability of -200mA. The device offers a DC current gain (hFE) ranging from 220 to 475 at VCE = 5V and IC = 2mA, ensuring consistent performance in linear circuits.

 

With a typical transition frequency (ft) of 100MHz and a maximum VCE saturation voltage of 650mV at 100mA, this transistor is suitable for moderate-speed switching and analog signal processing. The total power dissipation is rated at 250mW at 25°C ambient temperature on an FR4 PCB, with an operating junction temperature range of -65°C to 150°C.

 

The transistor is housed in a surface-mount SOT23 package (TO-236AB), which is compact and suitable for automated assembly. The marking code is 3F%, where % indicates the manufacturing site. This component is RoHS3 compliant and has an MSL of Level 1 (unlimited).

 

Typical applications include general-purpose switching, signal amplification, and driver stages in consumer electronics, industrial controls, and portable devices. The BC857B is the PNP complement to the NPN BC847B, allowing complementary circuit designs.
