EL817(S1)(TA)-V

Overview

The EL817(S1)(TA)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output and operates with a DC input. The device provides high isolation voltage of 5000 Vrms between input and output terminals. It supports a current transfer ratio ranging from 50% to 600% at a forward current of 5mA and collector-emitter voltage of 5V. The component is designed for surface mount installation in a compact small outline package.

Feature Summary

High isolation voltage capability between input and output circuits
Wide current transfer ratio range for flexible signal transmission
Surface mount packaging for compact circuit board integration
Compliance with lead-free and RoHS environmental standards

Applications

Signal isolation in digital communication interfaces
Switching power supply feedback loops
Microcontroller input/output isolation
Industrial control system signal coupling

Procurement Notes

Verify the specific suffix TA indicates tape and reel packaging configuration when sourcing. Confirm UL approval number E214129 and VDE approval number 132249 are required for your region's safety compliance. Ensure the operating temperature range of -55°C to +110°C meets your thermal design requirements before finalizing procurement specifications.

Selection Notes

Select this component when surface mount technology is preferred over through-hole alternatives in the EL817 family. Consider the 5000 Vrms isolation rating for applications requiring robust galvanic separation. Verify that the NPN phototransistor output characteristics align with your load driving requirements and logic level compatibility needs.

Part Context

This part belongs to the EL817 series of transistor output optocouplers produced by Everlight Electronics. The series offers various packaging options including DIP and SMD configurations. The EL817(S1)(TA)-V specifically denotes the surface mount variant with tape and reel delivery, distinguishing it from tube-packed or through-hole versions within the same electrical specification family.
