Overview
The EL3H7(H)-G is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output with a maximum collector-emitter voltage of 80V and a continuous collector current of 50mA. The device provides 3750Vrms isolation voltage between input and output circuits. It operates within a temperature range of -55°C to +110°C. The component is housed in a tube package.
Feature Summary
- Provides electrical isolation via infrared LED and NPN phototransistor interface
- Supports high insulation voltage for safety barrier applications
- Operates across extended industrial temperature ranges
Applications
- General purpose signal isolation
- Microcontroller interface circuits
- Power supply feedback loops
Procurement Notes
Verify the specific CTR bin, as the (H) suffix denotes a particular Current Transfer Ratio range. Confirm package type and RoHS compliance status through official manufacturer documentation before procurement. Check availability status as this part may be subject to lifecycle changes or limited distribution channels.
Selection Notes
Select this component when high isolation voltage and wide operating temperature are required. Ensure the NPN output configuration matches the load requirements. Verify that the 50mA collector current limit is sufficient for the application. Compare CTR specifications against other variants in the EL3H7 series to match circuit gain needs.
Part Context
This part belongs to the EL3H7-G series of ultra-small SSOP optocouplers from Everlight. The series offers various CTR bins and packaging options. The EL3H7(H)-G specifically utilizes a tube package format. It is designed for surface mount assembly in compact electronic designs requiring galvanic isolation.
Replacement Considerations
Check for direct substitutes within the EL3H7 family with different CTR bins or packaging. Verify pinout compatibility with alternative brands offering similar 4-pin SSOP transistor output optocouplers. Ensure replacement parts meet the same 3750Vrms isolation and temperature rating requirements.
