2SA1535AR

Single Bipolar Transistors Overview

The Panasonic 2SA1535AR is a silicon PNP epitaxial planar power transistor designed for low-frequency driver and high-power amplification applications. It operates with a maximum collector current of 1 A and a peak collector current of 1.5 A. The device features a collector-emitter voltage rating of -150 V for the standard variant and -180 V for the 'A' suffix version. It achieves a transition frequency (fT) of up to 200 MHz and maintains a collector power dissipation capacity of 15 W at 25°C. Packaged in an EIAJ SC-67 TO-220F-A1 format, it serves as a complementary pair to the 2SC3944 series.

Single Bipolar Transistors Procurement Notes

Verify the specific voltage rating required for your design, as the 'A' suffix denotes a higher collector-emitter breakdown voltage compared to the standard model. Confirm the package type matches your thermal management strategy, as the TO-220F-A1 requires appropriate heat sinking for full power dissipation. Check the latest product standards on the manufacturer's website to ensure availability and confirm if the component falls under maintenance or discontinued status before finalizing procurement plans.

Single Bipolar Transistors Selection Notes

Select this component when designing amplifier circuits requiring a robust PNP driver capable of handling significant current swings. Ensure the base drive current meets the minimum requirements for saturation at the intended operating load. Consider the complementary 2SC3944 series for balanced push-pull configurations. Evaluate the thermal resistance of your mounting solution against the 15 W dissipation limit to maintain junction temperatures within safe operational boundaries during continuous use.
