BSS79C Description

Short technical summary and product information.

The BSS79C is an NPN general purpose amplifier transistor designed for medium power amplification and switching applications requiring collector currents up to 500mA. It features a maximum collector-emitter voltage of 40V, collector current of 800mA, and power dissipation of 350mW. The device offers a DC current gain (hFE) of at least 100 at 150mA and 10V, with a typical current gain bandwidth product of 250MHz. Switching characteristics include typical delay and rise times of 10ns, storage time of 265ns, and fall time of 60ns. Collector-base capacitance is typically 8pF. The transistor is housed in a SOT-23-3 surface mount package with gull wing leads and a lead pitch of 0.95mm. It can operate over a junction temperature range of -55°C to 150°C. The part is manufactured using process 19 and is similar to the BCW65C. Compliance data indicates RoHS3 compliance, REACH unaffected, and MSL level 1, though these are unverified.
