2N4957 Description

Short technical summary and product information.

The SESCOCEM 2N4957 is a general-purpose PNP silicon transistor designed for applications such as VHF-UHF amplification. It features a hermetically sealed TO-72 metal can package.

 

Key electrical characteristics include a maximum collector-emitter voltage (VCEO) of 30V, a maximum collector-base voltage (VCBO) of 30V, and a maximum emitter-base voltage (VEBO) of 3V. The continuous collector current (IC) is rated at 30mA, with a maximum power dissipation of 200mW at 25°C, derated linearly above that temperature.

 

This transistor operates within a junction temperature range of -65°C to +200°C and a storage temperature range of -65°C to +200°C. It is available in a chip configuration as well, with a chip geometry of 0006. The part is referenced under MIL-PRF-19500/426 and offers qualification levels including JAN, JANTX, JANTXV, JANS, JANSR, and JANSF.
