BC857BLP4-7B Description

Short technical summary and product information.

The BC857BLP4-7B is a PNP small-signal bipolar junction transistor from Diodes Incorporated. It features a minimum collector-emitter breakdown voltage of -45V and a maximum collector current of -100mA. The device offers a DC current gain (hFE) of 220 minimum at 2mA collector current and 5V collector-emitter voltage, with a transition frequency of 100 MHz typical.

 

This transistor is designed for general-purpose switching and amplification applications where space is critical. It is housed in the ultra-compact X2-DFN1006-3 package, which has a footprint of 0.6mm² and a height of just 0.4mm, making it suitable for low-profile and high-density PCB designs. The package is surface-mount and uses NiPdAu terminal finish for excellent solderability.

 

The BC857BLP4-7B is fully RoHS3 compliant, lead-free, and halogen- and antimony-free (green device). It has a moisture sensitivity level of 1 per J-STD-020, allowing unlimited floor life. The device is rated for operation over a junction temperature range of -55°C to +150°C.
