BC556BTFR Description

Short technical summary and product information.

The BC556BTFR is a PNP epitaxial silicon transistor from On Semiconductor, part of the BC556/BC557/BC558/BC559/BC560 family. It is designed for switching and amplifier applications, with a high voltage rating of VCEO = -65 V and collector current capability of -100 mA DC (-200 mA peak). The transistor offers a DC current gain (hFE) range of 110 to 800 at VCE = -5 V, IC = -2 mA, making it suitable for a variety of general-purpose circuits.

 

Key electrical characteristics include a collector-emitter saturation voltage of -300 mV at IC = -10 mA, IB = -0.5 mA, and a current gain bandwidth product (fT) of 150 MHz typical. The transistor is low-noise with a noise figure of 2 dB typical (10 dB max) at low current. The maximum power dissipation is 500 mW at 25°C ambient, with a derating factor of 4.0 mW/°C above 25°C.

 

The device is housed in a TO-92-3 package (TO-226-3, TO-226AA) with formed leads for through-hole mounting. The package lead spacing is 2.54 mm. It is available in tape and reel packaging. The transistor is Pb-free, halogen free/BFR free, and RoHS compliant (unverified compliance data). The junction temperature range is -65 to +150°C.
