Single Bipolar Transistors Procurement Notes

Verify that the ordering suffix matches the required shipping configuration. The -AE suffix indicates a box quantity of 1,000 pieces, whereas non-AE variants are supplied in bags of 500. Confirm the specific hFE rank (S or T) if precise gain thresholds are necessary for the design. Ensure compliance with RoHS standards as indicated by the Pb Free marking.

Single Bipolar Transistors Selection Notes

Select this component when a robust NPN transistor with high current handling is required for switching applications. The wide SOA and low saturation voltage make it suitable for driving loads such as relays and lamps efficiently. Consider the specific hFE rank requirements during selection to ensure adequate base drive margins are met under varying load conditions.
