Overview
The EL814S1(TU)-V is a single-channel optoisolator featuring an infrared emitting diode optically coupled to a phototransistor detector. It utilizes a surface-mount 4-SMD package and provides high isolation voltage of 5000 Vrms between input and output circuits. The device supports a maximum collector-emitter voltage of 80 V and operates within a temperature range of -55°C to +110°C. Key electrical parameters include a typical forward voltage of 1.2 V, a maximum forward current of 60 mA, and a current transfer ratio ranging from 50% to 150%. Rise and fall times are specified at 7 µs and 11 µs respectively under standard test conditions.
Feature Summary
- Features two infrared emitting diodes connected in inverse parallel for AC input response capability
- Provides high isolation voltage between input and output terminals
- Offers wide operating temperature range suitable for demanding environments
- Compliant with RoHS standards and free of lead
Applications
- AC signal detection circuits
- Industrial control systems requiring galvanic isolation
- Signal transmission across isolated boundaries
Procurement Notes
Verify the specific suffix TU indicates surface mount packaging distinct from DIP variants. Confirm RoHS compliance status and UL/VDE recognition numbers match current regulatory requirements. Ensure the CTR bin matches application sensitivity needs as ratios vary significantly between units.
Selection Notes
Select this component when AC input handling is required due to the inverse parallel diode configuration. Compare rise and fall times against switching speed requirements. Verify package dimensions fit PCB layout constraints compared to through-hole alternatives like the standard EL814.
Part Context
This part belongs to the EL814 series by Everlight Electronics, which includes various packages and performance grades. The S1 designation typically denotes specific Current Transfer Ratio bins. The TU suffix identifies the surface mount form factor, differentiating it from the traditional DIP-4 packaging found in other series members.
Replacement Considerations
EL814S1(A)(TU)-V offers similar specifications with potential variations in CTR grading or forward voltage tolerances. Verify pinout compatibility and isolation voltage ratings before substitution.
