PC357N1TJ00F

Transistor, Photovoltaic Output Optoisolators Overview

The PC357N1TJ00F is a single-channel transistor output optocoupler from the Sharp PC357NJ0000F series. It features an infrared emitting diode optically coupled to an NPN phototransistor in a Mini-flat-4 surface-mount package. Key electrical parameters include a collector-emitter breakdown voltage of 80 V, a maximum forward current of 50 mA, and a typical forward voltage of 1.2 V. The device provides an isolation voltage of 3750 Vrms with a power dissipation of 170 mW. Switching characteristics specify rise and fall times of 18 µs. It operates within a temperature range of -30°C to +100°C.

• Utilizes a compact Mini-flat-4 surface-mount package for efficient PCB space utilization

Transistor, Photovoltaic Output Optoisolators Applications

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

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify component status carefully as multiple sources indicate this specific part number is obsolete or end-of-life. Confirm availability through authorized distributors or check for active replacement series within the PC357NJ family. Ensure the ordering suffix matches required specifications, as variations exist within the series. Cross-reference datasheets to confirm pinout and electrical ratings before finalizing procurement plans.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a low-profile SMD optocoupler with moderate speed (18 µs) is required. The 80 V collector-emitter voltage suits low-voltage logic interfacing. Consider the Mini-flat-4 footprint for assembly constraints. Verify that the CTR ranking meets system gain requirements, as options vary by suffix. Ensure thermal management supports the 170 mW dissipation limit in the intended enclosure.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the PC357NJ0000F series manufactured by Sharp Microelectronics. The series offers various Current Transfer Ratio (CTR) rankings distinguished by alphanumeric suffixes. While the base PC357N model is widely used, the specific '1TJ' suffix variant indicates a particular production run or specification tier that may no longer be actively manufactured.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Public sources explicitly identify the PC357N1TJ00F as obsolete. Check for active equivalents within the PC357NJ0000F series, such as PC357N2J000F or PC357N3J000F, which share the same Mini-flat-4 package and core electrical characteristics. Verify compatibility before substitution.
