Overview
The EL817(M)(D) is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an infrared emitting diode optically coupled to an NPN phototransistor detector in a DIP-4 package with 0.4-inch lead spacing. Key electrical parameters include a maximum collector-emitter voltage of 35 V, a maximum collector current of 50 mA, and a forward current of 20 mA. The device offers a minimum isolation voltage of 5000 Vrms and operates within a temperature range of -55 °C to +110 °C.
Feature Summary
- High isolation voltage between input and output
- Compact dual-in-line package with extended lead spacing
- RoHS compliant and lead-free construction
Applications
- General-purpose signal isolation
- Switching power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix codes against official datasheets to confirm lead form and packaging type. Ensure compliance requirements match project specifications. Confirm availability status through authorized channels as distribution varies by region.
Selection Notes
Select this component for applications requiring standard DIP mounting with wider lead pitch. Verify that the CTR range meets circuit gain requirements. Check thermal limits for high-temperature environments.
Part Context
This part belongs to the EL817 series of photocouplers. Variants exist in surface mount and different lead configurations. The M suffix specifically denotes the 0.4-inch lead spacing option.
Replacement Considerations
Check for direct equivalents from other manufacturers offering similar CTR ranges and isolation ratings. Verify pinout compatibility before substitution.
