Panasonic 2SA1528

The 2SA1528 is a PNP epitaxial planar silicon transistor with on-chip bias resistors R1=2.2 kΩ and R2=10 kΩ, designed for switching applications. It has a collector current rating of 500 mA and a collector dissipation of 600 mW. The device withstands a maximum collector-to-base and collector-to-emitter voltage of 50 V and an emitter-to-base voltage of 6 V. The junction temperature is rated to 150 °C. The gain-bandwidth product is 250 MHz, with a typical DC current gain of 50 at VCE=(-)5 V and IC=(-)10 mA. Input ON-state voltage ranges from 0.7 V to 3.0 V, and input OFF-state voltage from 0.5 V to 0.9 V. The package is a SANYO NP-case with dimensions of 6.0 mm × 4.0 mm × 1.3 mm, and pinout is identified as emitter, collector, base.
