Overview
The EL817(M)(C) is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with an NPN phototransistor detector, providing electrical isolation between input and output circuits. The device features a maximum collector-emitter breakdown voltage of 35 V and supports a continuous forward current of up to 50 mA. It offers a high isolation voltage rating of 5000 Vrms and operates within a temperature range of -55 °C to +110 °C. The component is housed in a DIP-4 package with a lead spacing of 10.16 mm (0.4 inches), designated by the 'M' suffix.
Feature Summary
- High isolation voltage capability between input and output terminals
- Compact dual-in-line package with extended lead spacing for through-hole mounting
- Compliance with international safety standards including UL, VDE, and CSA approvals
Applications
- Signal isolation in industrial control systems
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix against the manufacturer datasheet to confirm lead form and spacing requirements. Ensure the procurement source provides valid certification documentation for UL, VDE, and RoHS compliance. Confirm that the component matches the specified DIP-4 package dimensions and electrical ratings before integration into the design.
Selection Notes
Select this component when a standard 4-pin DIP footprint with 10.16 mm lead spacing is required for through-hole assembly. Consider the CTR specifications and isolation voltage ratings relative to the application's noise immunity needs. Verify compatibility with the target operating temperature range and ensure the phototransistor output characteristics meet the load requirements.
Part Context
The EL817 series represents a widely used family of general-purpose optocouplers from Everlight. The EL817(M)(C) variant specifically denotes the M-type package configuration, which distinguishes it from standard or surface-mount variants. This series is recognized for its reliability in providing galvanic isolation in various electronic applications.
Replacement Considerations
Cross-reference with other EL817 series variants such as EL817(C) or EL817(S)(C) only if package type and lead spacing requirements are compatible. Verify pinout and electrical parameters match exactly before substitution.
