Overview
The EL3021S(TA)-V is a Triac & SCR Output Optocoupler manufactured by Everlight Electronics. It features a GaAs infrared emitting diode optically coupled to a zero-crossing triac output detector. The device provides high isolation voltage of 5000 Vrms and supports an operating temperature range from -55°C to +100°C. Key electrical parameters include a minimum breakover voltage of 400 V, a maximum forward current of 60 mA, and a peak surge current of 1 A.
Feature Summary
- Integrates a GaAs infrared LED with a zero-voltage crossing triac output for precise switching control.
- Provides high insulation voltage capability between input and output circuits.
- Compliant with RoHS standards and lead-free manufacturing processes.
Applications
- Solid-state relay driver circuits
- Motor control systems requiring zero-crossing detection
- AC power switching applications
Procurement Notes
Verify the specific suffix (TA) indicates the tape-and-reel packaging format when ordering. Confirm compliance requirements such as UL and VDE approvals against the latest official datasheet revision. Ensure the selected variant matches the required package type and thermal specifications for the target application environment.
Selection Notes
Select this component for applications requiring random-phase triggering with zero-crossing output characteristics. Compare the 400 V breakover voltage rating against the system's peak line voltage to ensure adequate margin. Consider the surface-mount package dimensions for PCB layout constraints and verify the operating temperature range meets environmental demands.
Part Context
This part belongs to the EL302X series of Triac & SCR Output Optocouplers from Everlight. The series includes variants with different breakover voltages and package options. The EL3021S(TA)-V specifically denotes the surface-mount version with tape-and-reel packaging, designed for automated assembly processes in consumer and industrial electronics.
Replacement Considerations
Check for direct substitutes within the EL302X family or equivalent offerings from other manufacturers that match the 6-pin SMD package, 5000 Vrms isolation, and 400 V breakover voltage specifications. Verify pinout compatibility and thermal performance before substitution.
