With a transition frequency of 150 MHz, it is built for medium-speed switching and linear regulation in power supplies, motor pre-drive stages, and DC-DC converter circuits. The 15 W maximum power dissipation is specified for the DPAK footprint on a standard PCB — derate for elevated ambient temperature and limited copper area. ## Vce(sat) and hFE — switching efficiency Saturation voltage is 400 mV maximum at 150 mA base drive and 3 A collector current. DC current gain minimum is 200 at 100 mA, 2 Vce. ## DPAK package — board fit and thermal path The DPAK (TO-252-3) is a common surface-mount power package with a metal tab that carries the collector. The tab is electrically live — account for creepage and clearance if heatsinking to a grounded plane. No last-time-buy or end-of-life notices are documented.","metaTitle":"STD1802T4 NPN Transistor, 60V 3A DPAK, 150MHz","metaDescription":"STD1802T4 NPN transistor: 60V Vceo, 3A Ic, 150MHz fT, DPAK surface mount.
