Overview
The EL3H7(E)(TB)-G is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with an NPN phototransistor detector, encapsulated in a green compound within a 4-SSOP package. The device provides an isolation voltage of 3750 Vrms and supports a maximum collector-emitter voltage of 80V. It operates within a temperature range of -55°C to +110°C, featuring a typical forward voltage of 1.2V and a maximum power dissipation of 200mW.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using optical coupling technology.
- Features a compact surface-mount 4-SSOP package designed for automated assembly processes.
- Utilizes an NPN phototransistor output stage for reliable signal transmission across isolation barriers.
Applications
- Industrial control systems requiring signal isolation
- Consumer appliances with mains interface requirements
- Communication equipment needing ground loop elimination
Procurement Notes
Verify the specific Current Transfer Ratio (CTR) binning associated with the (E) suffix against project requirements, as performance varies within the series. Confirm the tape-and-reel packaging format matches automated handling capabilities. Ensure the 4-SSOP footprint aligns with the designated PCB layout. Cross-reference the RoHS compliance status with current regulatory standards before finalizing procurement orders.
Selection Notes
Select this component when a standard NPN phototransistor output is sufficient for the application logic levels. The 3750 Vrms isolation rating makes it suitable for basic insulation requirements in low-to-medium speed digital interfaces. Consider the thermal characteristics and operating temperature range to ensure reliability under expected environmental conditions.
Part Context
This part belongs to the EL3H7-G series of transistor output optocouplers from Everlight Electronics. The series is characterized by its use of green encapsulant and availability in various package configurations including SOIC and SSOP. The (TB) suffix indicates tape-and-reel packaging, while the (E) denotes a specific CTR grouping within the product line.
Replacement Considerations
Direct substitutes include other parts within the EL3H7-G family such as EL3H7(B)(TB)-G or EL3H7(C)(TB)-G, provided their respective CTR bins meet the design specifications. Verify pinout compatibility and package dimensions before substitution.
