Overview
The ELD213(TA) is a dual-channel phototransistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode and a phototransistor in an 8-pin SOP package to provide electrical isolation between input and output circuits. The device offers an insulation voltage of 3750Vrms and supports a maximum collector-emitter voltage of 80V per channel. It operates within a temperature range of -55°C to 110°C, with a typical turn-on time of 5µs and turn-off time of 4µs. The current transfer ratio is specified at a minimum of 100% when driven by a forward current of 10mA.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using infrared LED and phototransistor technology.
- Features dual independent channels for simultaneous signal transmission or power control applications.
- Designed for robust performance across extended industrial temperature ranges.
Applications
- Digital logic signal transmission and level shifting
- Power supply control and switching circuits
- Electrical isolation between different system grounds
Procurement Notes
Verify the specific suffix (e.g., TA, V) against the manufacturer's latest datasheet to ensure compatibility with required packaging and compliance standards. Confirm availability status as product lifecycles may change. Cross-reference pinout configurations with official documentation before integration into PCB designs to prevent installation errors.
Selection Notes
Select this component when dual-channel isolation is required within a compact surface-mount footprint. Ensure the application voltage does not exceed the 80V collector-emitter rating. Verify that the required isolation voltage meets or exceeds the 3750Vrms specification. Consider the operating temperature range if the environment exceeds standard commercial limits.
Part Context
This part belongs to the ELD series of transistor output optocouplers from Everlight. These devices are designed for general-purpose isolation tasks where moderate speed and high reliability are necessary. The SOP-8 package allows for automated assembly and space-efficient board layouts compared to through-hole alternatives.
Replacement Considerations
Check for direct substitutes such as the ELD213(TA)-V variant, which shares similar electrical characteristics. Verify pin compatibility and isolation ratings before substituting with other dual-channel optocouplers from different manufacturers.
