2SB14460RA

Single Bipolar Transistors Overview

The Panasonic 2SB14460RA is a silicon PNP epitaxial planar transistor designed for low-frequency power amplification. It features an MT-2-A1 package with a collector connected to the case. Key electrical ratings include a collector-emitter voltage of -50 V, a continuous collector current of -5 A, and a peak collector current of -7 A. The device has a collector power dissipation of 1 W at 25°C ambient temperature. Electrical characteristics specify a forward current transfer ratio (hFE) ranging from 60 to 340 depending on the rank, a transition frequency of 70 MHz, and a maximum collector-emitter saturation voltage of 0.3 V under specified pulse measurement conditions.
