BC548BRL1G

Single Bipolar Transistors Overview

The BC548BRL1G is an NPN silicon epitaxial planar transistor from onsemi, designed for amplifier and switching applications. It features a collector-emitter voltage of 30 Vdc and continuous collector current of 100 mAdc. The device operates within a junction temperature range of -55°C to +150°C with total device dissipation of 625 mW at 25°C ambient. Electrical characteristics include a DC current gain (hFE) ranging from 200 to 450 at IC=10mA/VCE=5V, and a current-gain-bandwidth product (fT) between 150 MHz and 300 MHz.

Single Bipolar Transistors Feature Summary

• NPN epitaxial silicon construction suitable for general-purpose amplification
• High DC current gain optimized for low-noise signal processing
• Lead-free package compliant with environmental directives

Single Bipolar Transistors Applications

• General-purpose amplifier circuits
• Low-noise audio pre-amplifiers
• Electronic switching applications

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix RL1G confirms tape and reel packaging containing 2000 units per reel. Confirm the G suffix indicates lead-free compliance. Ensure the component matches the CASE 29-11 TO-92 mechanical outline and Style 17 pin configuration (Collector, Base, Emitter). Validate RoHS status against the latest manufacturer documentation.

Single Bipolar Transistors Selection Notes

Select this variant when automated surface-mount or bulk assembly processes require tape and reel delivery. The B grading provides a moderate gain range compared to C variants. Verify that the 30 V collector-emitter rating meets circuit requirements. Consider thermal derating factors if operating above 25°C ambient temperature.

Single Bipolar Transistors Part Context

This component belongs to the BC546/BC547/BC548 series of NPN silicon transistors manufactured by onsemi. The series utilizes an epitaxial planar design in a TO-92 package. The BC548B variant specifically targets applications requiring a mid-range DC current gain, complementing the lower gain A grade and higher gain C grade options within the same family.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include BC548BTA and BC548BG, which share identical electrical ratings and TO-92 packaging. Verify pinout compatibility as Style 17 (Collector-Base-Emitter) is standard for these part numbers.
