BC548BRL1

Single Bipolar Transistors Overview

The BC548BRL1 is an NPN silicon epitaxial planar transistor from the BC546/547/548 series, manufactured by onsemi. It features a maximum collector-emitter voltage (VCEO) of 30 V and a continuous collector current (IC) of 100 mA. The device operates within a junction temperature range of -55°C to +150°C with a total power dissipation of 625 mW at 25°C ambient. Electrical characteristics include a DC current gain (hFE) ranging from 200 to 450 at IC=2.0 mA and VCE=5.0 V, and a transition frequency (fT) between 150 MHz and 300 MHz.

Single Bipolar Transistors Feature Summary

Single Bipolar Transistors Procurement Notes

Verify that the ordering suffix RL1 corresponds to the Tape & Reel packaging format specified in the official documentation. Confirm RoHS compliance status if required by project specifications, as indicated by the G suffix variant. Ensure component authenticity through authorized distribution channels to maintain reliability standards.

Single Bipolar Transistors Selection Notes

Select this component when a specific hFE binning of 200-450 is required for consistent circuit performance. Consider the TO-92 package constraints regarding thermal dissipation limits. Evaluate the complementary BC558B for push-pull configurations. Verify voltage headroom requirements against the 30 V limit before implementation.

Single Bipolar Transistors Part Context

This part belongs to the widely used BC54x family of general-purpose NPN transistors. The 'B' suffix denotes a specific DC current gain grouping distinct from A or C variants. The 'RL1' suffix indicates tape and reel packaging for automated assembly processes, differentiating it from bulk or ammo box versions.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include BC548B, BC548BG, and BC548BZL1G, provided they match the required gain bin and packaging type. Cross-manufacturer equivalents must be verified against the absolute maximum ratings and electrical characteristics defined in the datasheet.
