EL4502M-V

Overview

The EL4502M-V is a high-speed optocoupler manufactured by Everlight Electronics Co Ltd. It features a single channel with a transistor output configuration housed in an 8-pin DIP package. The device supports data rates up to 1 Mb/s and provides isolation voltage of 5000 Vrms. Key electrical parameters include a forward current of 16 mA, forward voltage of 1.45 V, reverse voltage of 5 V, and power dissipation of 100 mW. The current transfer ratio ranges from 19% to 50%. Operating temperatures span from -55°C to +100°C.

Feature Summary

• High-speed signal transmission capability supporting 1 Mb/s data rates
• Robust electrical isolation rated at 5000 Vrms for safety compliance
• Wide operating temperature range suitable for industrial environments

Applications

• Industrial communication interfaces requiring galvanic isolation
• Microcontroller input/output isolation circuits
• Signal transmission in noisy electrical environments

Procurement Notes

Verify the specific suffix variant against official Everlight documentation to ensure compatibility with design requirements. Confirm package type and pinout alignment before integration. Check for RoHS compliance status in the latest datasheet revision. Ensure supplier sources components directly from authorized channels to guarantee authenticity and traceability.

Selection Notes

Select this component when high-speed digital isolation is required within a standard DIP footprint. Consider the 1 Mb/s speed limit and transistor output characteristics for circuit matching. Evaluate thermal management needs given the 100 mW power dissipation rating. Compare isolation voltage requirements against system safety standards to confirm suitability.

Part Context

This part belongs to Everlight's high-speed optocoupler series designed for reliable signal transfer across isolated boundaries. The EL4502M-V variant specifically denotes the transistor output version in an 8-pin DIP package. It serves as a critical interface component in systems demanding noise immunity and electrical separation between control and load sides.

Replacement Considerations

Cross-reference with EL4502 or EL4502M variants if pin-compatible alternatives are needed. Verify that substitute parts maintain identical isolation voltage and data rate specifications. Ensure output type matches the original transistor configuration to avoid circuit redesign.
