Single Bipolar Transistors Procurement Notes

Verify the specific suffix F3TR against official ROHM documentation to confirm the tape-and-reel packaging configuration. Ensure the component meets RoHS compliance requirements for your target market. Confirm that the application does not involve automotive equipment, as this product is classified as standard grade and is explicitly not recommended for such use cases.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with 3 A current capacity and 30 V breakdown voltage is required in a compact DFN package. Consider the hFE range of 200 to 500 for base drive calculations. Verify thermal management needs given the 1 W power dissipation limit in the small form factor. Ensure the design environment stays within the specified -55°C to +150°C storage and operating temperature limits.

Single Bipolar Transistors Part Context

This part belongs to ROHM's lineup of surface-mount transistors designed for general electronic equipment. It serves as a complement to NPN variants like the 2SCR542 series. The DFN2020-3S package allows for space-constrained PCB layouts while maintaining robust electrical performance for medium-power tasks in consumer and industrial electronics.
