• Logic level translation stages

Procurement Notes

Verify the specific suffix TE85L against the manufacturer's official datasheet to confirm tape and reel specifications. Ensure the component meets RoHS compliance requirements for your manufacturing process. Cross-reference the SMV package dimensions with your PCB footprint library to guarantee mechanical compatibility before finalizing procurement orders.

Selection Notes

Select this component when a dual NPN pre-biased transistor is required for space-constrained designs. The integrated resistor network reduces external component count compared to discrete solutions. Consider the 50 V rating and 100 mA current limit to ensure operation within safe boundaries for low-power signal switching tasks.

Part Context

This part belongs to Toshiba's RN series of digital transistors, which combine bipolar junction transistors with internal biasing networks. The TE85L suffix indicates a specific taping format for surface-mount technology. These devices are designed to replace multiple discrete components, simplifying schematic design and reducing board space in consumer electronics and industrial control systems.

Replacement Considerations

Consult official substitution lists for equivalent dual NPN pre-biased transistors from other manufacturers. Verify that alternative parts match the 50 V voltage rating, 100 mA current capacity, and SMV package outline to maintain mechanical and electrical compatibility.
