2SB1203T-H-TL-E

Single Bipolar Transistors Overview

The onsemi 2SB1203T-H-TL-E is a PNP bipolar junction transistor (BJT) designed for high-current switching applications. It features a maximum collector current of 5 A and a collector-emitter voltage rating of 50 V. The device utilizes silicon technology and is housed in a compact MCPH-6 surface-mount package. Key electrical characteristics include a low collector-to-emitter saturation voltage, a transition frequency (fT) supporting fast switching speeds, and a DC current gain range typically between 200 and 560. The component is rated for a power dissipation of 1 W and operates at temperatures up to +150°C.
