Overview
The EL3012S(TA) is a single-channel Triac output optocoupler manufactured by Everlight Electronics. It integrates a Gallium Arsenide infrared emitting diode with a monolithic silicon random phase photo Triac. The device provides an isolation voltage of 5000 Vrms and supports a peak breakdown voltage (VDRM) of 250 V. Key electrical parameters include a maximum forward current of 60 mA, a forward voltage of 1.18 V, and a power dissipation of 330 mW. It operates within a temperature range of -55°C to +100°C and is housed in a PDIP-6 Gull Wing package.
Feature Summary
- Integrates a GaAs infrared LED with a monolithic silicon random phase photo Triac for robust signal isolation.
- Provides high insulation capability with a rated isolation voltage of 5000 Vrms between input and output circuits.
- Features a compact surface-mount compatible PDIP-6 Gull Wing package design suitable for automated assembly.
Applications
- Interfacing electronic controls with power triacs for AC load management
- Solenoid and valve control systems
- Lamp ballast driver circuits
Procurement Notes
Verify the specific suffix designation against the manufacturer's latest documentation to ensure correct packaging and compliance status. Confirm availability through authorized distributors as supply may be restricted. Cross-reference the component marking with the official datasheet to prevent substitution errors during procurement.
Selection Notes
Select this component when random phase triggering is acceptable for the application, as it lacks zero-crossing circuitry. Ensure the load voltage does not exceed the 250 V peak breakdown rating. Verify that the required isolation voltage meets or exceeds 5000 Vrms for safety compliance in mains-connected designs.
Part Context
This part belongs to the EL301X series of Triac output optocouplers from Everlight. It shares the same functional architecture as variants like the EL3011S1-V but differs in specific electrical ratings and packaging configurations. The series is designed for general-purpose AC switching applications requiring galvanic isolation.
Replacement Considerations
Direct substitutes within the same family include the EL3011S1-V and EL3012S1-V. Verify pinout compatibility and electrical ratings before substitution. Alternative packages such as SMD versions require careful review of thermal and mechanical constraints.
