2SA1746 Description

Short technical summary and product information.

The 2SA1746 is a silicon PNP epitaxial planar transistor from Sanken designed for general-purpose switching and chopper regulator applications.

 

Key electrical ratings include a maximum collector-emitter voltage (VCEO) of -50 V, continuous collector current (IC) of -12 A (pulse rating -20 A), and power dissipation of 60 W at case temperature 25°C. The device offers a minimum DC current gain (hFE) of 50 at VCE = -1 V and IC = -5 A, with a low collector-emitter saturation voltage (VCE(sat)) of -0.5 V maximum at IC = -5 A and IB = -80 mA. Typical transition frequency is 25 MHz.

 

The transistor is housed in a TO-3PF through-hole package with a weight of 6.5 g. It is RoHS compliant and has an MSL of 1 (unlimited).
