Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix '500E' to confirm the surface-mount variant and RoHS compliance status. Ensure the procurement specification matches the required packaging format, such as reel or cut tape, as availability varies by distributor. Cross-reference the manufacturer part number with official Broadcom documentation to validate authenticity and technical specifications before ordering.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a surface-mount solution is required for single-channel isolation with moderate speed requirements. The 5000 Vrms rating suits applications needing robust dielectric strength. Compare the 70 V collector-emitter voltage and 50 mA current limits against load requirements. Consider the 4 µs/3 µs switching speeds for timing constraints in the target circuit design.
