Overview
The EL3021S(TB) is a random-phase triac driver photocoupler manufactured by Everlight Electronics Co., Ltd. It features a compact 6-SMD surface-mount package designed for small footprint applications and low power consumption. The device provides electrical isolation with a 5000Vrms isolation voltage rating and supports an operating temperature range of -55°C to +100°C. It is classified as a Triac & SCR Output Optocoupler intended for high-reliability signal isolation in power control circuits.
Feature Summary
- Compact 6-SMD surface-mount package design
- High reliability triac and SCR output capability
- Random-phase triac driver functionality
Applications
- Triac driver circuits requiring random-phase triggering
- SCR output isolation interfaces
- Power control systems with limited board space
Procurement Notes
Verify component authenticity through authorized channels due to potential availability constraints. Confirm specific suffix variations against official Everlight documentation to ensure correct packaging and pin configuration. Check current lifecycle status as some variants may be obsolete or restricted in certain regions.
Selection Notes
Select this component when a surface-mount solution is required for triac isolation. Ensure the 6-SMD form factor fits the target PCB layout. Verify that the random-phase characteristic aligns with the load requirements, as it differs from zero-crossing drivers. Confirm thermal limits meet the application's operational environment.
Part Context
This part belongs to the EL3021 family of optocouplers from Everlight. It serves as the surface-mount equivalent to through-hole DIP versions, offering similar electrical performance in a smaller profile. The series is designed for industrial and consumer power switching applications where galvanic isolation is critical.
Replacement Considerations
EL3042S1(TB) is listed as a related module for isolating triac and SCR signals up to 5kVrms. Verify functional compatibility before substitution, as pinouts and internal circuitry may differ between specific model numbers within the manufacturer's portfolio.
