EL3082S1(TA)

Triac, SCR Output Optoisolators Overview

The EL3082S1(TA) is a surface-mount zero-crossing triac driver optocoupler manufactured by Everlight Electronics. It integrates an aluminum gallium arsenide infrared emitting diode with a sensitive gate triac output in a 6-pin SMD package. The device provides high isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a peak repetitive off-state voltage (VDRM) of 800 V, a maximum forward current (IF) of 60 mA, and a forward voltage (VF) of 1.5 V. The unit operates within a temperature range of -55°C to +100°C and features zero-voltage crossing capability for reduced electromagnetic interference.

Triac, SCR Output Optoisolators Procurement Notes

Verify component authenticity through authorized Everlight distributors or certified agents. Request official datasheets and certification documents to confirm compliance with RoHS standards and safety approvals such as UL and VDE. Ensure storage conditions meet moisture sensitivity level requirements prior to surface mount assembly processes.

Triac, SCR Output Optoisolators Selection Notes

Select this component for applications requiring precise phase-angle control with minimal switching transients. The 800 V blocking voltage suits most standard AC line voltages. Confirm that the 6-pin SMD footprint aligns with PCB layout constraints and thermal management requirements for the specific enclosure design.

Triac, SCR Output Optoisolators Part Context

This part belongs to the EL308X series of zero-crossing triac driver optocouplers. The series shares common architectural features including GaAs LED inputs and sensitive gate triac outputs. Variants within the family differ primarily by peak off-state voltage ratings, ranging from 250 V to 800 V, while maintaining consistent isolation and package specifications.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes include other EL308X series variants such as EL3083S1(TA) if voltage ratings permit. Cross-brand equivalents require matching isolation voltage, zero-crossing functionality, and SMD pinout compatibility. Verify trigger current requirements to ensure adequate drive signal margins.
