The 2SB1570 is a silicon PNP epitaxial planar Darlington transistor from Sanken Electric. It features a high DC current gain (hFE) of 5000 to 30000 at VCE = -4V and IC = -7A, making it well suited for audio amplifier output stages and series regulator applications.
With a maximum collector-emitter voltage of -150V and a collector current rating of -12A, this device provides robust switching and linear amplification capability. The typical transition frequency is 50 MHz, supporting audio frequency applications. The collector-emitter saturation voltage is a maximum of -2.5V at IC = -7A and IB = -7mA.
The transistor dissipates up to 150W at a case temperature of 25°C and operates at a maximum junction temperature of 150°C. It comes in a 3-ESIP through-hole package (MT-200) with a typical package weight of 18.4 g. The complementary NPN part is the 2SD2401.
