Single Bipolar Transistors Procurement Notes

Verify the specific hFE binning classification required for your design, as the datasheet defines Q and R grades with distinct gain ranges. Confirm that the SPT package dimensions align with your PCB footprint requirements. Ensure application circuits incorporate safety measures such as derating and fail-safe designs to prevent physical injury or fire in the event of component failure.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with a -32V collector-emitter voltage rating and -1A continuous current capacity is needed. The device is suitable for designs requiring low saturation voltage to minimize power loss during conduction. Consider its complementary relationship with the 2SD1858 if matched pairs are required for push-pull amplifier stages or similar configurations.

Single Bipolar Transistors Part Context

This part belongs to ROHM's medium power transistor lineup, specifically engineered for general-use electronic devices.
