BC637RL1G

Single Bipolar Transistors Overview

The BC637RL1G is an NPN silicon bipolar junction transistor manufactured by onsemi. It is housed in a TO-92-3 through-hole package and configured as a single device. The component supports a maximum DC collector current of 1 A and a collector-emitter voltage (VCEO) of 80 V. Key electrical parameters include a collector-base voltage (VCBO) of 80 V, an emitter-base voltage (VEBO) of 5 V, and a power dissipation rating of 625 mW. The gain-bandwidth product (fT) is specified at 200 MHz, with a minimum DC current gain (hFE) of 25. Operating temperatures range from -55 °C to +150 °C.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix RL1G against official datasheets to confirm packaging format and compliance status. Confirm availability status as distribution channels may list obsolete or limited stock items. Ensure the procurement source provides valid traceability documentation for the silicon material and manufacturing origin.

Single Bipolar Transistors Selection Notes

Select this component when an NPN transistor with 80 V breakdown and 1 A continuous current capacity is required in a TO-92 package. Compare hFE minimums and saturation voltages against circuit requirements. Consider thermal management needs given the 625 mW power dissipation limit in the standard plastic housing.

Single Bipolar Transistors Part Context

This part belongs to the BC639 series family of NPN transistors produced by onsemi. It shares similar structural characteristics with other members of the series but is distinguished by its specific electrical ratings and packaging configuration. The component is designed for use in discrete semiconductor applications requiring reliable performance in standard through-hole mounting scenarios.

Single Bipolar Transistors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with direct replacements based on matching pinouts, voltage ratings, and current capabilities before implementation.
