2SC15670R

Single Bipolar Transistors Overview

The Panasonic 2SC15670R is a silicon NPN epitaxial planar power transistor designed for low-frequency high-power driver applications. It operates with a collector current of 0.5 A and peak collector current of 1 A, dissipating up to 1.2 W at 25°C. The device features a transition frequency of 120 MHz and offers a forward current transfer ratio ranging from 130 to 330 depending on the specific rank classification. Packaged in a TO-126B-A1 format, it provides direct heat sink mounting without requiring an additional insulation plate.

Single Bipolar Transistors Feature Summary

• Optimized for use as a driver stage in low-frequency audio amplifiers delivering 40 W to 100 W output
• TO-126B package design allows direct installation to a heat sink without requiring an insulating plate
• High collector-emitter voltage rating ensures robust operation under open-base conditions

Single Bipolar Transistors Applications

• Low-frequency high-power amplifier driver stages
• General-purpose switching circuits
• Standard electronic equipment such as office machines and measuring instruments

Single Bipolar Transistors Procurement Notes

Verify the exact suffix 'R' against official Panasonic documentation to confirm reel packaging specifications. Confirm the active lifecycle status directly with the manufacturer or authorized distributors, as this component may be subject to planned maintenance or discontinuation protocols.

Single Bipolar Transistors Selection Notes

Select the 2SC15670R when a compact NPN power transistor is required for low-frequency driver applications. Ensure the thermal management strategy accommodates the 1.2 W dissipation limit without an insulator. Verify that the required hFE gain falls within the standard 130 to 330 range provided by the datasheet.

Single Bipolar Transistors Part Context

This component belongs to the 2SC1567 series of silicon NPN transistors manufactured by Panasonic Electronic Components. It serves as the complementary counterpart to the 2SA0794 PNP transistor, facilitating push-pull configurations in amplifier designs. The series is engineered specifically for general-purpose low-frequency power driving tasks.

Single Bipolar Transistors Replacement Considerations

Officially documented complementary parts include the 2SA0794 and 2SA0794A. Cross-referencing other manufacturers requires verifying matching VCEO, IC, and package dimensions.
