BC858BLT1G Description

Short technical summary and product information.

The BC858BLT1G is a PNP silicon bipolar junction transistor designed for general-purpose amplification and switching applications. It provides a collector-emitter voltage (VCEO) rating of -30 V and a collector-base voltage (VCBO) of -30 V, with a maximum continuous collector current of -100 mA and a peak current rating of -200 mA. The emitter-base voltage is rated at -5.0 V.

 

This device exhibits a minimum DC current gain (hFE) of 220 at Ic = 2 mA and Vce = 5 V, and a typical transition frequency of 100 MHz. Collector-emitter saturation voltage is specified as a maximum of 650 mV at Ic = 100 mA and Ib = 5 mA. Power dissipation is rated at 300 mW on an alumina substrate and 225 mW on an FR-5 board, with junction-to-ambient thermal resistances of 417 °C/W and 556 °C/W, respectively. Operating and storage junction temperature range is -55°C to +150°C.

 

The transistor is housed in a SOT-23-3 (TO-236) surface-mount package with three leads for collector, base, and emitter connections. The device is Pb-free, halogen free/BFR free, and RoHS compliant.
