Overview
The EL816(S1)(TA)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode optically coupled to an NPN phototransistor detector. The device provides high isolation voltage of 5000 Vrms between input and output circuits. It features a compact surface-mount DIP-4 package design compliant with RoHS standards. Key electrical parameters include a collector-emitter breakdown voltage of 80 V minimum, maximum forward current of 50 mA, and maximum on-state current of 50 mA. The unit operates within a temperature range of -55°C to +110°C.
Feature Summary
- High isolation voltage capability between input and output circuits
- Compact surface-mount small outline package design
- RoHS compliant and lead-free construction
- Wide operating temperature range for industrial environments
Applications
- Signal isolation in microprocessor systems
- Switching power supply feedback loops
- Solid-state relay driver circuits
- Level shifting between different voltage domains
Procurement Notes
Verify the specific suffix TA against the manufacturer's latest datasheet to confirm pinout orientation and tape-and-reel specifications. Ensure compliance with regional environmental regulations such as RoHS. Confirm availability status as distribution channels may vary. Cross-reference the part number with official Everlight documentation to avoid counterfeit components during sourcing.
Selection Notes
Select this component when surface-mount assembly is required for space-constrained designs. The NPN phototransistor output suits applications needing standard switching characteristics. Verify that the 5000 Vrms isolation rating meets the safety requirements of the target application. Consider the -55°C to +110°C operating range for extreme environment deployments.
Part Context
This part belongs to the EL816 series of transistor output optocouplers from Everlight. The series offers various packaging options including through-hole and surface-mount configurations. The S1 designation typically indicates a specific surface-mount footprint variant within the broader EL816 family, designed for automated PCB assembly processes.
Replacement Considerations
Direct replacements must match the 4-pin SMD form factor and NPN phototransistor output type. Verify equivalent isolation voltage ratings and current transfer ratio specifications. Check for compatible pin assignments to ensure board-level interchangeability without redesign.
