BC638ZL1G

Single Bipolar Transistors Overview

The BC638ZL1G is a PNP silicon transistor manufactured by onsemi, housed in a TO-92 package. It features a collector-emitter voltage of -60 Vdc and a continuous collector current of -0.5 Adc. The device provides a total device dissipation of 625 mW at 25°C ambient temperature. Electrical characteristics include a DC current gain ranging from 25 to 160 at -150 mA, and a current gain-bandwidth product of 150 MHz typical.

Single Bipolar Transistors Feature Summary

• PNP silicon construction for high-current applications
• Integrated Pb-Free packaging compliant with environmental standards
• High DC current gain capability across varying collector currents

Single Bipolar Transistors Applications

• General-purpose switching circuits
• Amplifier stages requiring PNP configuration
• Driver circuits for power MOSFETs or IGBTs

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix ZL1G corresponds to the required 2000-unit ammo box shipping format. Confirm that the Pb-Free designation aligns with project material requirements. Ensure the TO-92 package dimensions match the target PCB footprint constraints before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with a -60 V collector-emitter breakdown voltage is required. Consider the -0.5 A continuous collector current limit for load handling. Evaluate the thermal resistance values if operating near maximum dissipation limits in enclosed environments.

Single Bipolar Transistors Part Context

This part belongs to the BC638 series of high-current PNP transistors produced by onsemi. It shares the same electrical specifications as the standard BC638 but utilizes specific packaging and shipping configurations indicated by the ZL1G suffix. The device is designed for general-purpose amplification and switching tasks.

Single Bipolar Transistors Replacement Considerations

Direct substitutes within the same family include the BC638 and BC638G. Verify pinout compatibility and thermal characteristics when replacing with other PNP transistors in the TO-92 package.
