The 2SB1121T-TD-E is a PNP bipolar transistor from On Semiconductor, designed for applications such as voltage regulators, relay drivers, lamp drivers, and general electrical equipment. It utilizes FBET and MBIT processes to achieve low collector-to-emitter saturation voltage (-0.35V to -0.6V at 1.5A) and fast switching speeds (60ns turn-on, 350ns storage, 25ns fall time). The transistor offers a collector current rating of -2A continuous and -5A pulsed, with a collector dissipation of 500mW (1.3W when mounted on a ceramic substrate). It provides a DC current gain range of 140 to 400 at -100mA and a typical gain-bandwidth product of 150 MHz. The device is packaged in a surface-mount PCP package (TO-243AA, SC-62, SOT-89) and is supplied in tape and reel with 1000 pieces per reel. The maximum junction temperature is 150°C, and the storage temperature range is -55°C to +150°C.
