Overview
The EL3051S1(TB)-V is a surface-mount optoisolator featuring a single-channel random-phase triac output. It integrates a gallium arsenide infrared emitting diode with a monolithic silicon photo-triac. Key electrical parameters include a 5000 Vrms isolation voltage, a 600 V off-state voltage, and a minimum static dV/dt of 1 kV/µs. The device operates within a temperature range of -55°C to +100°C and complies with RoHS standards.
Feature Summary
- Random-phase triac output designed for zero-crossing noise immunity in AC control applications
- High isolation capability between input and output circuits for safety compliance
- Surface-mount packaging optimized for automated PCB assembly processes
Applications
- Solid-state relay interfaces
- AC motor speed control circuits
- Industrial valve and solenoid controls
Procurement Notes
Verify the specific suffix (TB-V) to confirm surface-mount tape-and-reel packaging and lead-free compliance. Ensure the procurement channel provides valid manufacturer documentation to confirm the component matches the EL305X series specifications rather than generic equivalents.
Selection Notes
Select this component when high dv/dt immunity is required for inductive loads. The 600V rating suits standard mains voltages. Verify that the surface-mount footprint aligns with the PCB design constraints compared to through-hole alternatives in the same series.
Part Context
This part belongs to the EL305X series from Everlight Electronics, which utilizes random-phase triacs. Unlike zero-crossing variants, these devices trigger immediately upon input signal activation, making them suitable for phase-angle control applications such as dimmers or precise power regulation.
Replacement Considerations
Direct replacements include other EL305X series variants like EL3052 or EL3053 if voltage ratings differ. Cross-reference pinouts and thermal characteristics carefully when substituting with components from different manufacturers offering similar triac output optocouplers.
