2SC4131

Single Bipolar Transistors Overview

The Sanken Electric USA Inc. 2SC4131 is a silicon NPN epitaxial planar transistor housed in an FM100 (TO-3PF) package. It features a collector-emitter breakdown voltage of 50V minimum and a continuous collector current rating of 15A. The device supports a maximum power dissipation of 60W at 25°C case temperature, with a junction temperature range from -55°C to +150°C. Key electrical characteristics include a DC current gain (hFE) ranging from 60 to 360 at IC=25mA, a typical transition frequency (fT) of 18MHz, and a low collector-emitter saturation voltage of 0.5V maximum at IC=5A.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against the official datasheet to confirm pinout compatibility and thermal resistance specifications. Ensure the procurement documentation explicitly references the FM100 (TO-3PF) package style. Confirm that the component meets the required safety certifications for the intended industrial or automotive environment before finalizing the purchase order.

Single Bipolar Transistors Selection Notes

Select this component for high-current switching applications requiring low saturation voltage. Evaluate the safe operating area curves to ensure the device can handle the specific pulse widths and duty cycles of the target circuit. Consider the thermal management requirements, as the 60W power rating depends on maintaining the case temperature at or below 25°C using an appropriate heatsink.

Single Bipolar Transistors Part Context

This part belongs to Sanken's lineup of silicon NPN epitaxial planar transistors designed for robust power switching. The FM100 package provides a reliable mechanical interface for through-hole mounting. The device is engineered to offer a balance between high current handling and fast switching speeds, making it suitable for medium-power conversion circuits.

Single Bipolar Transistors Replacement Considerations

Consult official cross-reference lists for direct replacements. Verify that any substitute maintains the same TO-3PF footprint and matches the 50V V(BR)CEO and 15A IC ratings.
