2SC6145

Single Bipolar Transistors Overview

The 2SC6145 is a Silicon NPN Epitaxial Planar Transistor designed for audio power amplifier applications. It features a collector-emitter breakdown voltage (VCEO) of 230 V and a maximum collector current (IC) of 15 A. The device provides a transition frequency (fT) of 60 MHz and a collector power dissipation (PC) of 160 W at a case temperature of 25 °C. DC current gain (hFE) ranges from 40 to 140 depending on the rank, with a typical value of 60 MHz at an emitter current of -2 A.

Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank required for your circuit design, as the component is available in R, O, and Y ranks with varying gain ranges. Confirm that the TO3P-3L package dimensions and screw torque specifications align with your heatsink mounting requirements. Ensure compliance with RoHS standards if lead-free processing is mandated by your manufacturing process.

Single Bipolar Transistors Selection Notes

Select this transistor when designing high-power audio amplifiers requiring a 230 V collector-emitter voltage and 15 A continuous current capability. Consider the thermal resistance characteristics and the need for adequate heat sinking to maintain junction temperatures within the 150 °C limit during operation.

Single Bipolar Transistors Part Context

Manufactured by Sanken Electric Co., Ltd., the 2SC6145 is part of their LAPT series. It utilizes a bare lead frame construction compliant with RoHS directives. The datasheet explicitly marks this component as 'Not Recommended for New Designs,' indicating it may be superseded by newer generations or phased out in favor of updated alternatives.

Single Bipolar Transistors Replacement Considerations

The official complementary PNP transistor is the 2SA2223. Designers should consult Sanken Electric for potential successor components given the 'Not Recommended for New Designs' status.
