Procurement Notes

Verify the complete part number including the suffix 'TRPBFREE' to ensure correct tape-and-reel packaging and lead-free compliance. Confirm that the supplier provides the official Central Semiconductor datasheet for the specific lot code. Check for any recent Product Change Notices (PCNs) or End-of-Life (EOL) announcements directly from the manufacturer before placing orders.

Selection Notes

Select this component when a small-form-factor NPN transistor is required for RF applications operating up to 1.45 GHz. Ensure the circuit design accommodates the 15V maximum collector-emitter voltage and 50mA current limits. Verify that the thermal management strategy supports the 350mW power dissipation rating within the specified -65°C to +150°C operating range.

Part Context

This component belongs to the Central Semiconductor ULTRAmini™ series of surface mount transistors. These devices are designed for space-constrained electronics requiring high-frequency performance. The CMPT5179 variant specifically targets RF uses where low voltage and moderate current are sufficient, distinguishing it from higher-power linear or switching transistors in the broader portfolio.
