PC357M0TJ00F

Overview

The PC357M0TJ00F is a transistor output optocoupler manufactured by Sharp Microelectronics. It features a single channel configuration housed in a 4-pin Miniflat surface-mount package. The device provides an isolation voltage of 3750 Vrms and utilizes an NPN phototransistor output. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum forward current of 50 mA, and a typical rise/fall time of 18 μs. The unit weight is approximately 100 mg.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Utilizes a compact surface-mount Miniflat-4 package for space-constrained designs
• Features fast switching characteristics with symmetric rise and fall times

Applications

• General-purpose signal isolation in industrial control systems
• Interface circuits for microcontrollers requiring galvanic separation
• Power supply feedback loops for voltage regulation

Procurement Notes

Verify component authenticity through authorized Sharp Microelectronics distributors or certified partners. Confirm RoHS compliance status and check for recent Product Change Notifications (PCNs) regarding manufacturing site changes. Ensure storage conditions adhere to moisture sensitivity levels specified in the datasheet to prevent package damage during reflow soldering processes.

Selection Notes

Select this component when a low-profile surface-mount solution is required for single-channel isolation. Consider the 80 V collector-emitter voltage rating and 50 mA output current capability against load requirements. Evaluate the 3750 Vrms isolation barrier strength for safety compliance needs. Compare thermal dissipation limits if operating near maximum temperature extremes.

Part Context

This part belongs to the Sharp PC357NJ series of transistor output optocouplers. The series is characterized by high current transfer ratio rankings and robust insulation capabilities. Variants within the family often differ by CTR grading or specific packaging suffixes, but share core electrical performance metrics and physical dimensions suitable for standard SMD assembly lines.

Replacement Considerations

Public records indicate that the PC357M0TJ00F is obsolete and no longer manufactured. Engineers should consult Sharp's official discontinuation notices for recommended replacement parts within the same product line or equivalent specifications from other qualified suppliers.
