IS3051

Overview

The IS3051 is a single-channel optoisolator manufactured by Isocom Components 2004 LTD. It features a triac output configuration designed for AC load switching applications. The device provides an isolation voltage rating of 5000Vrms, ensuring robust electrical separation between input and output circuits. It is housed in a standard 6-pin DIP package, facilitating through-hole mounting on printed circuit boards. The component utilizes infrared technology to transmit signals across the isolation barrier.

Feature Summary

• Triac output stage suitable for alternating current load control
• High insulation voltage capability for safety-critical isolation
• Standard dual-in-line package format for easy integration

Applications

• Solid-state relay implementations
• AC motor speed control circuits
• Lighting dimmer systems

Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm pinout compatibility and packaging type. Ensure the required isolation voltage rating meets the target application safety standards before procurement. Confirm lead times with authorized distributors as manufacturing schedules may vary.

Selection Notes

Select this component when a simple triac output is required for low-power AC switching. Consider the 5000Vrms isolation rating for environments requiring significant voltage separation. Evaluate the DIP-6 footprint constraints against available board space during the design phase.

Part Context

Isocom Components 2004 LTD specializes in high-performance infrared optoelectronic devices. The company produces optocouplers and optoswitches that often serve as replacements for discontinued industry-standard parts. Their products are manufactured to global recognized industry standards.

Replacement Considerations

Check pin-to-pin compatibility with existing designs using similar triac-output optoisolators. Verify that the replacement part meets or exceeds the original isolation voltage and current transfer ratio requirements.
