BC639-16ZL1

Single Bipolar Transistors Overview

The BC639-16ZL1 is an NPN silicon transistor in a TO-92 package. It features a collector-emitter voltage of 80 V and a continuous collector current of 1.0 A. The device offers a minimum DC current gain of 40 at 150 mA and 2 V, with a transition frequency of 200 MHz. Total device dissipation is rated at 625 mW at 25°C ambient temperature. The component operates within a junction temperature range of -55 to +150 °C.

Single Bipolar Transistors Feature Summary

• High current capability up to 1.0 A
• Low voltage operation with 80 V collector-emitter rating
• Enhanced breakdown voltage of 120 V for the -16 variant

Single Bipolar Transistors Applications

• General-purpose switching applications
• Amplifier circuits
• Driver stages requiring high current handling

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix ZL1 corresponds to the Ammo Box packaging configuration as documented in the manufacturer's ordering information table. Confirm that the -16 designation indicates the enhanced 120 V breakdown characteristic distinct from standard BC639 variants before finalizing procurement specifications.

Single Bipolar Transistors Selection Notes

Select this component when a high-current NPN transistor with low saturation voltage is required. The -16 suffix provides increased collector-emitter breakdown voltage compared to standard versions. Ensure thermal management aligns with the 625 mW dissipation limit at ambient temperatures above 25°C using the specified derating factor.

Single Bipolar Transistors Part Context

This part belongs to the BC635, BC637, and BC639 family of NPN medium power transistors manufactured by onsemi. The BC639-16 variant specifically denotes an enhanced breakdown voltage specification while maintaining the same physical package and general electrical characteristics as the standard BC639 series.

Single Bipolar Transistors Replacement Considerations

Standard BC639 devices may be considered if the 120 V breakdown voltage of the -16 variant is not required. Verify pinout compatibility and thermal resistance values when substituting with equivalent parts from other manufacturers.
