BC637 NPN High Current Transistor

Description

The BC637 Transistor is a miniature NPN transistor for use in small signal amplification and relay output switching circuits. The BC637 transistor is housed in a small through-hole TO-92 plastic package. The transistor has a power rating of 625mW, with a maximum collector current of 1A. The complementary for the BC637 NPN Transistor is the BC638 PNP Transistor, which can be used together in amplifier output stages. The BC637 Pinout is Base-Collector-Emitter, left to right (with the transistor laying on the flat side).
