BSR19A Description

Short technical summary and product information.

The BSR19A from NXP Semiconductors is an NPN high voltage transistor suitable for general purpose switching and amplification applications, particularly in telephony. It is housed in a compact SOT23 plastic package.

 

This transistor offers a low current capability of up to 300 mA and high voltage ratings, with a collector-base voltage (VCBO) of up to 180 V for the BSR19A variant and 160 V for the BSR19. The collector-emitter voltage (VCEO) is rated up to 160 V for BSR19A and 140 V for BSR19.

 

Key electrical characteristics include a DC current gain (hFE) ranging from 60 to 250 at 10 mA and 5 V, and a transition frequency (fT) of 100 to 300 MHz at 10 mA and 10 V. The device also has low leakage currents, with collector cut-off current (ICBO) typically in the nanoampere range at rated voltages.

 

Designed for surface mounting, the SOT23 package is standard for many electronic assemblies. The thermal resistance from junction to ambient is 500 K/W when mounted on an FR4 printed-circuit board.
