Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'TL-E' against official onsemi documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the requested part number matches the exact electrical ratings required for your design, as variations exist within the 2SD1805 series. Cross-reference the manufacturer's latest datasheet for any potential product change notifications or obsolescence alerts before finalizing procurement plans.

Single Bipolar Transistors Selection Notes

Select this component when a robust NPN transistor is needed for switching loads up to 5 A in space-constrained designs. The 20 V collector-emitter rating suits low-voltage logic and power control interfaces. Consider the thermal management requirements associated with the 1 W power dissipation limit in the TP package. Verify that the 180 MHz transition frequency meets the speed requirements of the target application circuit.

Single Bipolar Transistors Part Context

This device belongs to the 2SD1805 family of high-current switching transistors manufactured by onsemi. The series is characterized by its ability to handle significant current while maintaining low saturation voltages.
