Single Bipolar Transistors Procurement Notes

Verify the specific datasheet revision and manufacturer source before procurement. Confirm that the component matches the FM20 (TO-220F) package dimensions and pinout configuration required by your design. Ensure compliance with the stated absolute maximum ratings during operation. Check for any RoHS or environmental compliance documentation provided by the supplier. Validate that the part number suffix corresponds exactly to the intended specifications.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring high breakdown voltage up to 550 V and moderate current handling up to 7 A. Consider the thermal management requirements given the 35 W power dissipation limit at 25°C case temperature. Evaluate the switching speed characteristics against the circuit's frequency demands. Ensure the TO-220F package fits the available board space and mounting constraints.
