Single Bipolar Transistors Procurement Notes

Verify the manufacturer origin, as the model number corresponds to Blue Rocket components rather than Renesas Electronics Corporation. Confirm the specific suffix 'ND-A' against official datasheets to ensure correct pinout and hFE binning. Request the latest revision data sheet to validate electrical limits and thermal resistance values before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component for general-purpose amplification and low-speed switching tasks requiring moderate voltage handling. Ensure the application current remains within the 150mA limit and power dissipation stays below 250mW. Verify that the required gain falls within the specified 90 to 180 range for the chosen hFE class.

Single Bipolar Transistors Part Context
