PC81712NIP

Transistor, Photovoltaic Output Optoisolators Overview

The PC81712NIP is a single-channel transistor output optocoupler manufactured by Sharp Microelectronics. It features an NPN phototransistor output with a maximum collector-emitter voltage of 80 V and a maximum collector current of 50 mA. The device provides 5000 Vrms isolation voltage between input and output. Key electrical parameters include a forward current of 10 mA, a forward voltage of 1.2 V typical, and a collector-emitter saturation voltage of 200 mV maximum. The Current Transfer Ratio ranges from 160% to 400% at a test current of 500 µA. Switching characteristics specify typical rise and fall times of 4 µs and 3 µs, respectively. The component operates within a temperature range of -30°C to +100°C and is housed in a 4-SMD (gull-wing) package.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Provides high-voltage electrical isolation via a 5000 Vrms dielectric barrier between the infrared LED input and the NPN phototransistor output.
• Delivers signal transmission through a single channel using direct current input control for reliable switching applications.
• Utilizes a surface-mount 4-SMD gull-wing package designed for automated assembly processes.

Transistor, Photovoltaic Output Optoisolators Applications

• Signal isolation in microprocessor interface circuits
• Switch-mode power supply feedback loops
• Solid-state relay driver circuits

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify RoHS compliance status carefully as sources indicate non-compliance. Confirm availability as the part is listed as obsolete or discontinued in some distributor records. Check for specific ordering suffixes that may affect lead time or packaging. Ensure the supplier provides valid traceability documentation for this legacy component.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a standard SMD optocoupler with moderate CTR is required. Compare against the PC817X1NIP1B if higher current transfer ratio consistency is needed. Consider the PC81713NIP1B for different CTR specifications. Verify thermal management requirements given the 170 mW power dissipation limit in the SMD-4 package.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the PC817 series of transistor output optoisolators from Sharp Microelectronics. The series is widely recognized for general-purpose isolation tasks. The PC81712NIP specifically denotes the NPN output variant with a 4-SMD gull-wing footprint. It serves as a surface-mount alternative to through-hole versions like the PC81712NSZ.
