Overview
The EL817(S)(TB) is a single-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features an NPN phototransistor output and provides high isolation voltage of 5000 Vrms between input and output. The device is housed in a compact surface-mount 4-SMD package with gull-wing leads, specifically designed for tape and reel processing (Type II). Key electrical parameters include a collector-emitter breakdown voltage of 35V, a maximum forward current of 60mA, and a typical rise/fall time of 4µs/3µs. It operates within a temperature range of -55°C to 110°C.
Feature Summary
- High isolation voltage capability of 5000 Vrms ensures robust signal transmission across isolated circuits.
- Compact surface-mount 4-SMD package design facilitates automated assembly via tape and reel.
- Single-channel configuration with NPN phototransistor output for efficient DC signal coupling.
Applications
- Signal isolation in industrial control systems
- Interface circuits for microprocessors and logic devices
- Power supply feedback loops requiring galvanic isolation
Procurement Notes
Verify the specific suffix variants such as TA or VG against the required packaging type and compliance standards. Confirm that the surface-mount footprint matches the PCB layout requirements. Ensure the selected variant meets the necessary safety approvals like UL or VDE if required for the end application. Cross-reference the datasheet for exact CTR ranges and thermal specifications before finalizing the order.
Selection Notes
Select this component when a surface-mount solution is preferred over through-hole DIP packages for space-constrained designs. The EL817 series offers various lead spacing options; ensure the S-type designation aligns with the target PCB pad dimensions. Consider the current transfer ratio requirements and operating temperature range to ensure compatibility with the system's electrical environment and reliability standards.
Part Context
The EL817 series represents a family of photocouplers from Everlight Electronics, widely used for electrical isolation. The EL817(S)(TB) specifically denotes the surface-mount variant with gull-wing leads intended for tape and reel handling. This model continues the legacy of the standard EL817 while adapting to modern SMT manufacturing processes, maintaining the core performance characteristics of the original DIP version.
Replacement Considerations
Direct pin-to-pin replacements may include other EL817 surface-mount variants from Everlight, such as EL817(S)(C)(TB)-G, depending on the required Current Transfer Ratio (CTR) binning and specific safety certifications. Verify that substitute parts match the 4-SMD footprint and isolation voltage ratings.
