Single Bipolar Transistors Procurement Notes

Verify the suffix -Y-TP indicates specific tape-and-reel packaging and RoHS compliance status as per Micro Commercial Components documentation. Confirm the SOT-89 pinout alignment matches target PCB footprints prior to integration. Ensure storage conditions adhere to moisture sensitivity level requirements specified in the manufacturer datasheet to maintain solderability and electrical integrity during surface-mount reflow processes.

Single Bipolar Transistors Selection Notes

Select this component when circuit design requires an NPN transistor capable of handling 120 V collector-emitter voltage within a limited thermal envelope. The 800 mA current rating suits moderate load driving scenarios where space constraints necessitate the SOT-89 form factor. Consider the 120 MHz transition frequency for applications involving signal frequencies below this threshold. Evaluate thermal resistance parameters against expected power dissipation levels to ensure reliable long-term operation without active cooling mechanisms.
