Overview
The ELD207(TA)-V is a dual-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features an isolation voltage of 3750Vrms and operates within a temperature range of -55°C to 110°C. The device utilizes an 8-SOP surface mount package. Key electrical parameters include a maximum collector-emitter voltage of 80V, a typical forward voltage of 1.2V, and a maximum DC forward current of 60 mA. The current transfer ratio ranges from 100% to 200% at 10mA input. Saturation voltage is limited to 400mV, with typical switching times of 5µs on and 4µs off.
Feature Summary
- Dual-channel configuration for simultaneous signal isolation
- High insulation capability rated at 3750Vrms
- Extended operating temperature range suitable for harsh environments
- Low power consumption design optimized for portable applications
Applications
- Portable electronic devices requiring low power isolation
- Industrial control systems needing high isolation voltage
- Signal transmission between isolated circuits in automation equipment
Procurement Notes
Verify the specific suffix TA-V against the official Everlight datasheet to confirm pinout and packaging specifications. Ensure compliance with RoHS3 standards as indicated in distributor documentation. Confirm that the 8-SOP package dimensions match the target PCB layout requirements before finalizing procurement decisions.
Selection Notes
Select this component when dual-channel isolation is required within a compact surface-mount footprint. The high current transfer ratio ensures reliable switching performance. Consider the 80V output voltage limit and 60mA input current constraints during circuit design to ensure operation remains within safe electrical boundaries for the intended application environment.
Part Context
This part belongs to the ELD20x series of phototransistor output optocouplers. The series is characterized by low power consumption and high isolation ratings. The ELD207 variant specifically provides two independent channels in a single 8-pin SOP package, distinguishing it from single-channel counterparts in the same family.
Replacement Considerations
Consult the official Everlight datasheet for confirmed substitute part numbers within the ELD20x or ELD21x series. Verify pin compatibility and electrical parameter equivalence before substituting.
