PC354N1

Overview

The PC354N1 is a single-channel transistor output optocoupler manufactured by Sharp Microelectronics. It features an NPN phototransistor output and operates within a surface-mount SMD-4 package. The device provides high isolation with a rated insulation voltage of 3750 Vrms. Key electrical parameters include a minimum current transfer ratio of 400%, a maximum collector-emitter voltage of 80 V, and a maximum forward current of 50 mA. The typical rise and fall times are both 18 microseconds. It supports a power dissipation of 170 mW and functions reliably across a temperature range of -30°C to +100°C.

Feature Summary

High isolation capability with 3750 Vrms insulation voltage for safe signal transmission between isolated circuits.
High current transfer efficiency with a minimum CTR of 400% ensuring reliable switching performance.
Robust thermal stability operating effectively from -30°C to +100°C for diverse environmental conditions.

Applications

Industrial control systems requiring galvanic isolation
Signal interface circuits in measurement equipment
Power supply feedback loops

Procurement Notes

Verify the specific suffix '1' against the official Sharp datasheet to confirm it denotes the correct Current Transfer Ratio rank or variant. Ensure the ordering part number matches the exact specification sheet provided by Sharp Microelectronics. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement orders.

Selection Notes

Select this component when high current transfer ratio and fast switching speeds are required in a compact surface-mount form factor. The 80 V collector-emitter voltage rating suits low-voltage logic interfacing. Consider the 18 microsecond transition times for applications where moderate speed is acceptable without excessive propagation delay penalties.

Part Context

This component belongs to the PC354NJ0000F series of transistor output optocouplers. It is designed for general-purpose isolation tasks where high reliability and compact packaging are prioritized. The device integrates an infrared emitting diode and an NPN phototransistor on a single chip within a four-pin SMD enclosure.
