Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (TELS-TP6,F) against official Toshiba documentation to confirm packaging type and lead-free status. Ensure the component matches the required DIP4 form factor and isolation ratings for your design. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance requirements align with project specifications before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage and compact DIP4 packaging are required for transistor output applications. Consider the 80V collector-emitter voltage rating for load compatibility. Evaluate the 5000 Vrms isolation barrier for safety certification needs. Compare propagation delays if high-speed switching is critical, as standard phototransistors may have slower response times compared to logic outputs.
