2SA1962OTU

Single Bipolar Transistors Overview

The onsemi 2SA1962OTU is a PNP epitaxial silicon transistor housed in a TO-264 package with three pins. It supports a maximum DC collector current of -17 A and offers high power dissipation capabilities up to 150 W. The device features a collector-emitter voltage (VCEO) and collector-base voltage (VCBO) rating of -250 V, alongside an emitter-base voltage (VEBO) of -5 V. Key electrical parameters include a minimum DC current gain (hFE) of 55 and a transition frequency (ft) of 30 MHz. It operates within a temperature range from -50°C to +150°C junction temperature.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix OTU against official datasheets to confirm the TO-264 through-hole package configuration. Ensure the component meets the required thermal management specifications for 150 W dissipation. Confirm that the application design accounts for the -250 V voltage ratings and 30 MHz frequency limits. Validate compliance with relevant safety standards before integration into final products.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring high-voltage PNP switching or amplification with significant current handling. Consider the TO-264 package for its robust mechanical structure and thermal performance compared to smaller packages. Evaluate the complementary NPN counterparts, such as the 2SC5242 or FJA4313, for balanced push-pull amplifier configurations. Assess thermal resistance requirements to maintain junction temperatures within the specified operational limits.

Single Bipolar Transistors Part Context

This part belongs to the 2SA1962 series of high-power PNP transistors manufactured by onsemi. It is functionally related to other variants in the same family, such as the 2SA1943 in a TO-264 package with 150 W dissipation and the FJP1943 in a TO-220 package with lower power ratings. These components are commonly used in professional audio equipment and industrial power supplies where reliability and linearity are critical.

Single Bipolar Transistors Replacement Considerations

Official documentation identifies the 2SC5242 and FJA4313 as complementary NPN transistors for paired applications. Direct substitutes may include equivalent PNP transistors from other manufacturers with matching -17 A current, -250 V voltage, and TO-264 package constraints. Verify pinout compatibility and thermal characteristics before substitution.
