EL817(M)-VG

Overview

The EL817(M)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output and operates within a temperature range of -55°C to +110°C. The device provides high isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 35 V, a maximum forward current of 60 mA, and a typical rise/fall time of 6 µs/8 µs. The unit is housed in a DIP-4 package with 0.4-inch lead spacing.

Feature Summary

• Provides high electrical isolation between input and output circuits
• Features compact dual-in-line package design for through-hole mounting
• Includes certified safety approvals including UL, VDE, and SEMKO

Applications

• Power supply feedback loops
• Industrial control systems
• Appliance signal transmission

Procurement Notes

Verify the specific CTR bin (A, B, or C) required for your application, as performance varies significantly across bins. Confirm the suffix VG indicates RoHS compliance and halogen-free status. Ensure the M-type lead spacing matches your PCB footprint requirements before ordering.

Selection Notes

Select this component when high isolation voltage and standard switching speeds are required. Compare CTR specifications against circuit gain requirements. Verify thermal dissipation capabilities within the operating temperature range. Ensure compatibility with logic levels driving the input LED.

Part Context

This part belongs to the EL817 series of transistor output optocouplers. The series is widely used for general-purpose signal isolation. The M designation indicates specific lead form and spacing characteristics suitable for standard through-hole assembly processes.

Replacement Considerations

Check datasheets for equivalent parts from other manufacturers offering similar isolation voltages and pin configurations. Verify that substitute components meet the same safety certification requirements.
