2SA1907

Single Bipolar Transistors Overview

The Sanken 2SA1907 is a silicon PNP epitaxial planar transistor designed as the complement to the 2SC5099 NPN device. It features an absolute maximum collector current of 6 A and a collector-emitter breakdown voltage of -80 V. The component supports a maximum power dissipation of 60 W at 25°C case temperature, with a junction temperature range up to 150°C. Key electrical characteristics include a minimum DC current gain (hFE) of 50 and a typical transition frequency (fT) of 20 MHz. It utilizes the FM100 (TO-3PF) flange-mount package.

Single Bipolar Transistors Feature Summary

• Complementary pairing with the 2SC5099 NPN transistor for balanced push-pull configurations
• High-speed switching capability suitable for audio output stages
• Robust thermal performance with 60 W power dissipation capacity under specified conditions

Single Bipolar Transistors Applications

• Audio amplifier output stages
• General-purpose switching circuits
• Power supply regulation

Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank suffix (O, P, or Y) required for your design, as these indicate distinct gain ranges. Confirm the FM100 package dimensions match your PCB footprint. Ensure thermal management solutions align with the derating curves provided in the datasheet for ambient temperatures exceeding 25°C.

Single Bipolar Transistors Selection Notes

Select this component when a high-current PNP switch is needed to complement an NPN device like the 2SC5099. Consider the -80 V rating for low-voltage applications. Evaluate the thermal resistance requirements based on the expected load current and available heatsinking, as the 60 W rating assumes a 25°C case temperature.

Single Bipolar Transistors Part Context

This transistor belongs to Sanken's discrete bipolar transistor lineup, specifically engineered for complementary pairs. The 2SA1907 is paired with the 2SC5099 to ensure matched characteristics in audio and general-purpose power applications. The FM100 package provides a reliable mounting interface for heat dissipation.

Single Bipolar Transistors Replacement Considerations

Direct substitutes must match the PNP polarity, 6A current rating, and TO-3PF package. Verify that any replacement offers comparable hFE and fT specifications. Check if alternative manufacturers offer equivalent complementary pairs to maintain circuit balance.
