MJ21195G

Single Bipolar Transistors Overview

The MJ21195G is a silicon PNP power transistor manufactured by onsemi, designed for high-power audio and switching applications. It features a maximum collector current of 16 A and a collector-emitter voltage rating of 250 V. The device utilizes a TO-264 (TO-3P) through-hole package with a thermal resistance optimized for heatsink mounting. Key electrical specifications include a collector-base voltage of 400 V, an emitter-base voltage of 5 V, and a DC current gain (hFE) minimum of 25. Power dissipation reaches 200 W at case temperature, with a transition frequency of 4 MHz. Operating temperatures range from -65°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'G' indicates lead-free and halogen-free compliance status per the manufacturer's latest documentation. Confirm the package variant matches the required TO-264 footprint for PCB layout compatibility. Check for any recent product change notices regarding manufacturing site transfers or material updates that may affect long-term sourcing stability.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits requiring high current capacity with moderate voltage ratings. Ensure the thermal design accounts for the 200 W dissipation limit under worst-case operating conditions. Compare against complementary NPN devices like the MJ21196G for push-pull configurations. Validate that the drive circuitry can provide sufficient base current to maintain the transistor in saturation or active region as required by the application topology.

Single Bipolar Transistors Part Context

This part belongs to the MJ2119x series of high-power bipolar junction transistors. It serves as the PNP counterpart to the MJ21196G NPN device. The series is widely recognized in professional audio equipment and industrial power supplies. The TO-264 package provides superior heat dissipation compared to smaller plastic packages, making it suitable for chassis-mounted installations.

Single Bipolar Transistors Replacement Considerations

Direct functional substitutes within the same family include the MJL21195G, which shares identical electrical characteristics but may differ in packaging or compliance markings. Verify pinout compatibility before substitution. Cross-reference with other manufacturers' equivalents such as the 2SC2922 or 2SA1216 only if electrical parameters and thermal performance are strictly matched.
