2SC5101

Single Bipolar Transistors Overview

The Sanken Electric 2SC5101 is a silicon NPN triple diffused planar power transistor designed for audio and general-purpose applications. It serves as the complementary device to the 2SA1909 PNP transistor. The component features an FM100 (TO-3PFML) package with absolute maximum ratings of 200V collector-base voltage, 140V collector-emitter voltage, and 6V emitter-base voltage. It supports a continuous collector current of 10A and base current of 4A, with a collector power dissipation of 80W at 25°C case temperature. Electrical characteristics include a minimum DC current gain (hFE) of 50 at VCE=4V and IC=3A, a typical transition frequency (fT) of 20MHz, and a maximum collector-emitter saturation voltage of 0.5V.

Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank suffix (O, P, or Y) required for your design, as these indicate different gain ranges. Confirm that the TO-3PFML pinout matches your PCB footprint. Note that this component is marked as not recommended for new designs; ensure availability aligns with long-term production requirements before finalizing procurement plans.

Single Bipolar Transistors Selection Notes

Select the 2SC5101 when a high-voltage NPN power transistor is needed to pair with the 2SA1909 in push-pull configurations. Ensure the application operates within the 140V VCEO limit and requires the specific thermal characteristics of the FM100 package. Consider the hFE rank requirements for gain matching in balanced circuit designs.
