Overview
The EL3H7(C)(EB)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode and an NPN phototransistor within a compact surface-mount package to provide electrical isolation between input and output circuits. The device features a high isolation voltage of 3750 Vrms, ensuring robust safety standards for signal transmission across potential differences. It operates reliably within a wide temperature range from -55°C to +110°C. Key electrical parameters include a maximum collector-emitter voltage of 80V and a continuous collector current of 50mA. The component supports DC input signals and offers a typical forward voltage of 1.2V at a maximum forward current of 50mA.
Feature Summary
- Provides galvanic isolation between input and output circuits using optical coupling technology.
- Features a high insulation voltage rating suitable for demanding safety applications.
- Designed for surface-mount assembly with a compact footprint.
- Capable of operating in extreme ambient temperature environments.
Applications
- Digital logic signal transmission and level shifting
- Power supply control and switching circuits
- Electrical isolation between distinct system sections
Procurement Notes
Verify the specific suffix configuration against official Everlight documentation to ensure compatibility with required CTR grades and packaging formats. Confirm RoHS compliance status and lead times through authorized distributors, as availability may vary by region. Ensure storage conditions adhere to moisture sensitivity levels specified in the datasheet prior to reflow soldering.
Selection Notes
Select this component when high-voltage isolation is required in space-constrained designs. Consider the NPN phototransistor output characteristics and saturation voltage for load driving capabilities. Evaluate the thermal management requirements given the wide operating temperature range and power dissipation limits during continuous operation.
Part Context
This part belongs to the EL3H7 series of transistor output optocouplers from Everlight. The series is widely used for general-purpose isolation tasks. Variations in suffixes typically denote different Current Transfer Ratio (CTR) bins or packaging options such as tape and reel quantities rather than fundamental functional changes.
Replacement Considerations
Cross-reference with other EL3H7 variants like EL3H7(B)(TA)-VG or EL3H7(TA)-VG for alternative CTR specifications. Verify pinout compatibility and package dimensions before substitution to ensure mechanical fit on existing PCB layouts.
