2SA1488

Single Bipolar Transistors Overview

The Sanken Electric 2SA1488 is a silicon PNP epitaxial planar transistor designed for audio and general-purpose applications. It serves as the complement to the 2SC3851/A series. The device features a collector-emitter breakdown voltage of 60V, a maximum collector current of 4A, and a power dissipation rating of 25W at 25°C case temperature. Key electrical characteristics include a minimum DC current gain (hFE) of 40 at -1A/-4V, a typical transition frequency (fT) of 15MHz, and a collector-emitter saturation voltage of -0.5V maximum at -2A collector and -0.2A base currents. It is housed in a TO-220F (FM20) through-hole package.

Single Bipolar Transistors Feature Summary

• Complements the 2SC3851/A NPN transistor pair for matched performance
• Designed specifically for audio amplification and general-purpose switching circuits
• Utilizes an epitaxial planar silicon construction for reliability

Single Bipolar Transistors Applications

• Audio amplifier output stages
• General-purpose switching circuits
• Driver circuits requiring complementary PNP/NPN pairs

Single Bipolar Transistors Procurement Notes

Verify the specific suffix (e.g., 'A') against the required voltage rating, as the standard 2SA1488 has a 60V VCEO while the 2SA1488A offers 80V. Confirm the package type matches the target PCB footprint, as the datasheet specifies the FM20 (TO-220F) form factor. Ensure thermal management calculations account for the 25W dissipation limit at 25°C case temperature.

Single Bipolar Transistors Selection Notes

Select this component when a high-current PNP transistor is needed to match the 2SC3851/A NPN device. Consider the 60V versus 80V collector-emitter voltage options based on circuit requirements. Evaluate the thermal resistance characteristics if operating without an infinite heatsink or under natural cooling conditions to ensure safe junction temperatures are maintained.

Single Bipolar Transistors Part Context

This component belongs to Sanken Electric's discrete bipolar transistor lineup, focusing on power amplification.
