Overview
The EL817(S1)(B)(TA)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with an NPN phototransistor in a surface-mount SMD package, specifically the S1 type designed for tape and reel handling. The device provides high isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a collector-emitter breakdown voltage of 35 V, maximum forward current of 60 mA, and a typical current transfer ratio range associated with the B suffix classification. It operates within a temperature range of -55°C to +110°C.
Feature Summary
- High isolation voltage capability between input and output sections
- Surface-mount compatible S1 package configuration for automated assembly
- RoHS compliant construction with halogen-free materials
- Recognized by major safety agencies including UL, VDE, and CSA
Applications
- Industrial control systems requiring galvanic isolation
- Automation equipment signal transmission
- Noise-sensitive circuit interfaces
- Power supply feedback loops
Procurement Notes
Verify the specific suffix VG against the manufacturer's latest datasheet to confirm material composition and compliance status. Ensure the S1 package dimensions match the target PCB footprint. Confirm availability as distribution channels may vary due to lifecycle status. Cross-reference the B suffix CTR bin requirements with design specifications before ordering.
Selection Notes
Select this component when surface-mount technology is required for the EL817 series functionality. The S1 suffix indicates a specific lead bend suitable for reflow soldering on reels. Verify that the 5000 Vrms isolation rating meets the system's safety clearance requirements. Ensure the NPN phototransistor output configuration aligns with the downstream logic or driver interface needs.
Part Context
This part belongs to the EL817 family of photocouplers from Everlight. The family offers various packaging options including through-hole DIP and surface-mount variants. The EL817 series is widely used for general-purpose isolation applications. The specific model combines the standard EL817 electrical characteristics with specialized packaging and compliance attributes defined by its suffixes.
Replacement Considerations
Direct substitutes include other EL817 series variants such as EL817(S1)(B)(TA) or EL817(S1)(C)(TA), provided the current transfer ratio bin matches the application requirements. Generic replacements must maintain the same DIP-4 footprint and pinout compatibility.
