PC357M9J000F

Overview

The PC357M9J000F is a single-channel transistor output optocoupler manufactured by Sharp Microelectronics. It features an NPN phototransistor output housed in a Miniflat-4 surface-mount package. The device provides an isolation voltage of 3750 Vrms and supports a maximum collector-emitter voltage of 80 V with a collector current capacity of 50 mA. It operates within a temperature range of -30°C to +100°C, dissipating up to 170 mW. The component exhibits rise and fall times of 18 µs each, with a typical current transfer ratio of 600%.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits via optical coupling.
• Features a compact Miniflat-4 surface-mount package for efficient PCB space utilization.
• Delivers fast switching performance with symmetric rise and fall times.

Applications

• Industrial control systems requiring signal isolation
• Consumer appliance interface circuits
• General-purpose digital signal transmission

Procurement Notes

Verify the specific Current Transfer Ratio (CTR) ranking, as suffixes often denote binning ranges. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Ensure the Miniflat-4 footprint matches your PCB layout requirements. Check for lead-free soldering compatibility if required by your assembly process. Validate that the operating temperature range meets your environmental specifications.

Selection Notes

Select this component when a single-channel isolation solution with moderate speed is required. The 600% CTR variant suits applications needing higher gain without excessive input current. Consider the 80 V collector voltage limit for low-voltage logic interfacing. The Miniflat-4 package is suitable for dense surface-mount designs. Evaluate thermal dissipation capabilities under continuous operation conditions.

Part Context

This part belongs to the Sharp PC357NJ0000F series of transistor output optocouplers. The series offers various CTR rankings to accommodate different circuit gain requirements while maintaining consistent electrical characteristics and packaging. These components are designed for general-purpose isolation tasks in commercial and industrial electronics.

Replacement Considerations

Direct substitutes include other Sharp PC357N variants with matching CTR bins, such as PC357N1J000F or PC357N2J000F, provided their specific CTR ranges align with design needs. Cross-brand replacements require verification of pinout, isolation voltage, and package dimensions.
