TPC817MB C9G

Transistor, Photovoltaic Output Optoisolators Overview

The TPC817MB C9G is a single-channel transistor output optoisolator manufactured by Taiwan Semiconductor Corporation. It features a 4-DIP package with a wide body configuration (0.400 inch / 10.16 mm pitch). The device provides high isolation voltage of 5000Vrms and a creepage distance exceeding 7.62mm. Key electrical parameters include a collector-emitter voltage (Vceo) of 80V, maximum DC forward current (If) of 50mA, and output current per channel of 50mA. The typical rise and fall times are 4µs and 3µs respectively, with a saturation voltage (Vce sat) maximum of 200mV. Operating temperature range spans from -40°C to 100°C.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• High isolation voltage between input and output terminals
• Wide body DIP-4 package for enhanced creepage distance
• UL recognized component for safety compliance

Transistor, Photovoltaic Output Optoisolators Applications

• Programmable controllers
• System appliances and measuring instruments
• Telecommunication equipment signal transmission
• Home appliances such as fan heaters

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific CTR binning (130%-260% vs 80%-600%) against the datasheet revision, as different sources cite varying ranges. Confirm the package width matches the application board layout, as the MB suffix indicates a wider 0.400-inch DIP compared to standard 0.300-inch variants. Ensure RoHS and halogen-free compliance documentation is available for regulatory requirements.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage and wide body spacing are required in a DIP-4 form factor. Compare CTR specifications carefully, as performance varies significantly between manufacturing bins. Consider the 50mA output current capability and 80V Vceo rating for switching applications. Verify thermal management needs within the -40°C to 100°C operating range.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the TPC817 series of phototransistor photocouplers. It serves as an alternative to industry-standard PC817 devices but offers distinct packaging dimensions. The series is designed for general-purpose signal isolation in digital circuits. Taiwan Semiconductor positions this component for cost-sensitive applications requiring reliable galvanic isolation.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include other 4-DIP transistor output optocouplers with similar isolation ratings. Verify pinout compatibility and physical dimensions before substitution. Check if the replacement meets the same UL recognition file number E478892 or equivalent safety approvals.
