Overview
The EL3041S(TA) is a surface-mount Triac output optocoupler from Everlight Electronics. It integrates a GaAs infrared emitting diode with a zero-voltage crossing Triac driver. Key electrical parameters include a minimum off-state peak voltage of 400 V, an isolation voltage of 5000 Vrms, and a maximum forward current of 60 mA. The device operates within a temperature range of -55°C to +100°C and features a 6-SMD package.
Feature Summary
- Integrates zero-voltage crossing circuitry for reduced electromagnetic interference
- Provides high isolation voltage between input and output circuits
- Constructed with a GaAs infrared LED optically coupled to a Triac driver
Applications
- Solid-state relay control circuits
- Motor speed control systems
- Lighting dimmer applications
Procurement Notes
Verify the specific suffix (TA vs TB) against the required packaging format, as TA typically denotes tube packaging while TB indicates reel or cut tape options. Confirm RoHS compliance status and lead times directly with the manufacturer or authorized distributors, as availability may vary by region and production batch.
Selection Notes
Select this component when zero-crossing functionality is required to minimize switching noise in AC load control. Ensure the 400 V blocking voltage meets the peak line voltage requirements of the application. Verify that the 6-SMD surface mount footprint aligns with the PCB design constraints and thermal management needs.
Part Context
This part belongs to the EL304X series of zero-cross Triac driver photocouplers. The series includes variants with different voltage ratings such as 250V, 400V, 600V, and 800V. The EL3041 specifically denotes the 400V rating within this family of optically isolated TRIAC drivers designed for AC power switching applications.
Replacement Considerations
Check for direct pin-compatible substitutes within the EL304X series if voltage ratings differ. Verify functional equivalence regarding zero-crossing timing and holding current specifications before substituting with other manufacturers' TRIAC output optocouplers.
