PC12311NSZ

Overview

The PC12311NSZ is a single-channel transistor output optocoupler manufactured by Sharp Microelectronics. It features a GaAs infrared LED coupled to an NPN silicon phototransistor, providing electrical isolation with a high insulation voltage of 5000 Vrms. The device is designed for general-purpose signal switching and interface applications. Key electrical parameters include a minimum current transfer ratio of 100% at a forward current of 5 mA, with a maximum CTR of 250%. The unit is housed in a standard 4-DIP package with a 7.62 mm (0.300 inch) pin spacing, suitable for through-hole mounting.

Feature Summary

High isolation voltage capability of 5000 Vrms for robust circuit protection
Wide current transfer ratio range ensuring reliable signal transmission across varying conditions
Integrated NPN phototransistor output for direct logic interfacing

Applications

General-purpose signal isolation in industrial control systems
Interface circuits between microprocessors and peripheral devices
Switching power supply feedback loops

Procurement Notes

Verify the specific ordering suffix against the official datasheet to ensure compatibility with required packaging and tape-and-reel specifications. Confirm that the component meets RoHS compliance requirements if mandated by the end-product regulations. Check the lifecycle status, as this part may be subject to obsolescence notices or recommended replacement alternatives from the manufacturer.

Selection Notes

Select this component when a single channel of isolation with moderate current transfer characteristics is required. Ensure the application voltage does not exceed the collector-emitter breakdown limits. Consider the DIP-4 package dimensions for PCB layout constraints. Evaluate the operating temperature range to confirm suitability for the intended environmental conditions.

Part Context

This component belongs to Sharp Microelectronics' family of transistor output optocouplers. It shares functional similarities with other models in the series but differs in specific electrical ratings and packaging options. The PC12311NSZ is distinct from SCR or triac output variants, serving primarily as a digital switch rather than an AC load controller.
