PC357M2J000F

Overview

The PC357M2J000F is a single-channel transistor output optocoupler manufactured by Sharp Microelectronics. It features an NPN phototransistor output and utilizes a Mini-Flat 4-pin surface-mount package. The device provides an isolation voltage of 3750 Vrms and operates within a temperature range of -30°C to +100°C. Key electrical parameters include a maximum collector-emitter saturation voltage of 200 mV, a typical rise/fall time of 18 μs, and a power dissipation rating of 170 mW. The current transfer ratio is ranked between 130% and 600% at a forward current of 5 mA.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Features fast switching characteristics with symmetric rise and fall times
• Designed for surface-mount assembly in compact form factors

Applications

• Signal isolation in industrial control systems
• Interface circuits for microcontrollers and logic devices
• Power supply feedback loops

Procurement Notes

Verify the specific CTR ranking suffix (e.g., M2) against the manufacturer's datasheet to ensure the correct gain bin is selected for the application. Confirm that the Mini-Flat package dimensions match the PCB footprint requirements. Check for RoHS compliance status as indicated in the official documentation before finalizing procurement specifications.

Selection Notes

Select this component when high isolation voltage and compact size are required. Ensure the operating temperature range meets the environmental conditions. Verify that the input forward current limits are not exceeded during operation. Consider the CTR variation across the specified range when designing biasing networks for consistent performance.

Part Context

This part belongs to the PC357NJ0000F series of surface-mount optocouplers. It shares the same physical package and basic electrical structure with other variants in the series, differentiated primarily by their Current Transfer Ratio rankings. The series is designed for general-purpose signal isolation applications requiring small footprint solutions.

Replacement Considerations

Direct substitutes may include other PC357N variants with different CTR rankings, such as PC357N1J000F or PC357N9J000F, provided the gain requirements align. Verify pinout compatibility and isolation voltage ratings before substitution.
