PC357M7J000F

Overview

The PC357M7J000F is a single-channel transistor output optocoupler manufactured by Sharp Microelectronics. It features an NPN phototransistor output and operates within a temperature range of -30°C to +100°C. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum forward current of 50 mA, and a typical forward voltage of 1.4 V. The device provides an isolation voltage of 3750 Vrms and supports a maximum collector current of 50 mA. Current transfer ratio ranges from 200% to 600%, with rise and fall times of 18 μs each. Power dissipation is rated at 170 mW.

Feature Summary

Provides high-voltage electrical isolation between input and output circuits via optical coupling.
Features a fast switching response suitable for digital signal transmission applications.
Utilizes a compact surface-mount Mini-Flat package design for efficient PCB integration.

Applications

Digital signal isolation in industrial control systems
Signal transmission between microcontrollers and peripheral devices
Isolation interfaces in measurement and testing equipment

Procurement Notes

Verify the specific CTR ranking suffix (e.g., M7) against official Sharp datasheets to ensure correct gain binning. Confirm RoHS compliance status and UL certification details through authorized distributors. Ensure the Mini-Flat package dimensions match the target footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when high-speed digital isolation is required with a wide operating temperature range. The 3750 Vrms isolation rating makes it suitable for noisy environments. Compare the 200-600% CTR range against application load requirements to ensure adequate drive capability for the connected circuitry without exceeding maximum ratings.

Part Context

This part belongs to the PC357NJ0000F series of transistor output optocouplers. It shares common characteristics with other variants in the family, such as identical pinout and basic electrical limits, but differs in current transfer ratio grading. The Mini-Flat 4-pin package is standard for this series, offering a small form factor compared to traditional DIP packages.
