PC354N1TJ00F

Overview

The PC354N1TJ00F is a single-channel transistor output optocoupler manufactured by Sharp Microelectronics. It features an NPN phototransistor output with a maximum collector-emitter voltage of 80V and a maximum collector current of 1.5mA. The device provides an isolation voltage of 3750Vrms and operates within a temperature range of -30°C to +100°C. Key electrical parameters include a typical rise time of 4μs, a typical fall time of 3μs, and a DC current transfer ratio ranging from 50% to 150%. The component is housed in a 4-pin Mini-Flat surface-mount package.

Feature Summary

• High-speed switching capability with rapid rise and fall times for efficient signal transmission.
• Robust electrical isolation rated at 3750Vrms to protect low-voltage control circuits.
• Wide operating temperature range ensuring reliability in diverse environmental conditions.

Applications

• General-purpose signal isolation in industrial control systems
• Interface between microcontrollers and high-voltage loads
• Power supply feedback loops for voltage regulation

Procurement Notes

Verify the specific suffix designation against official datasheets to confirm performance rankings and packaging details. Ensure compatibility with existing PCB footprints for the 4-pin Mini-Flat configuration. Check for updated availability status as some variants may be marked obsolete or have limited stock. Confirm RoHS compliance requirements for your specific manufacturing process.

Selection Notes

Select this component when fast switching speeds are required compared to standard optocouplers. The 80V output voltage rating suits applications driving moderate load voltages. Consider the 1.5mA collector current limit when designing pull-up resistor values. The wide temperature range makes it suitable for automotive or outdoor industrial environments where thermal stability is critical.

Part Context

This part belongs to Sharp's PC354 series of high-speed optocouplers. It shares the same physical footprint and basic isolation characteristics with other members like the PC354NJ0000F but differs in channel count and specific CTR ranking. The series is designed for applications requiring reliable galvanic isolation with faster response times than conventional devices.

Replacement Considerations

Direct substitutes include the PC354N1J000F which shares similar electrical characteristics and pinout. Verify that any replacement maintains the 3750Vrms isolation rating and compatible switching speeds. Ensure the alternative device supports the required 1.5mA output current and 80V breakdown voltage.
