Single Bipolar Transistors datasheet and documents for BC635ZL1G

BC635ZL1G

Single Bipolar Transistors Overview

The BC635ZL1G is an NPN silicon transistor in a TO-92 package. It features a collector-emitter voltage of 45 Vdc and continuous collector current of 1.0 Adc. Total device dissipation is 625 mW at 25°C ambient, derating by 5.0 mW/°C above this temperature. The junction temperature range spans from -55 to +150 °C. DC current gain ranges from 25 to 250 at 5 mA and 40 to 250 at 150 mA. Thermal resistance is 200 °C/W junction-to-ambient and 83.3 °C/W junction-to-case.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix ZL1G against official documentation to confirm the tape and reel shipping configuration. Ensure the component meets Pb-free requirements if mandated by the design specifications. Cross-reference the exact part number with the manufacturer's current datasheet revision to validate all electrical parameters before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component when a medium power NPN transistor is required for driver stages or general-purpose switching. Consider the 1.0 A continuous current rating and 45 V breakdown voltage limits. Evaluate thermal management needs based on the specified junction-to-ambient thermal resistance and power dissipation derating curves provided in the datasheet.
