Single Bipolar Transistors datasheet and documents for 2SA0794AR

2SA0794AR

Single Bipolar Transistors Overview

The Panasonic 2SA0794AR is a silicon PNP epitaxial planar transistor designed for low-frequency output driver applications. It operates with a collector current of -0.5 A and peak current of -1 A. The 2SA0794 variant supports a collector-emitter voltage of -100 V, while the 2SA0794A variant reaches -120 V. Both share a -5 V emitter-base voltage rating. Power dissipation is rated at 1.2 W, with a junction temperature limit of 150 °C. Forward current transfer ratios range from 50 to 220 depending on the rank and operating conditions.

Single Bipolar Transistors Feature Summary

High collector-emitter voltage capability for robust operation
Optimized specifically as a driver stage for low-frequency amplifiers
TO-126B package design eliminates the need for an insulation plate during heat sink installation

Single Bipolar Transistors Applications

Driver stage for low-frequency audio amplifiers
Output drivers for 40 W to 100 W power amplifier systems
General-purpose low-frequency switching circuits

Single Bipolar Transistors Procurement Notes

Verify the specific suffix (2SA0794 vs 2SA0794A) to confirm the required collector-emitter voltage rating (-100 V or -120 V). Confirm that the TO-126B-A1 package dimensions align with the target PCB layout. Ensure thermal management strategies account for the 1.2 W power dissipation limit at elevated ambient temperatures.

Single Bipolar Transistors Selection Notes

Select this component when designing low-frequency output stages requiring high voltage tolerance without complex mounting hardware. The complementary NPN counterpart is the 2SC1567 series. Evaluate the hFE rank requirements based on the specific drive current needs of the amplifier circuit to ensure adequate gain margins.

Single Bipolar Transistors Part Context

This device belongs to the Panasonic 2SA0794 family of silicon PNP transistors. It serves as the PNP complement to the 2SC1567 NPN transistor. The series is engineered for general electronic equipment and standard applications, providing reliable performance in audio and signal processing contexts.

Single Bipolar Transistors Replacement Considerations

Official complementary parts include the 2SC1567 and 2SC1567A. Verify pinout compatibility and thermal characteristics before substituting with other TO-126B packages.
