Overview
The EL1017-G is a single-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features an NPN phototransistor output and provides 5000 Vrms potential isolation voltage between input and output circuits. The device is housed in a compact 4-pin SOP package with long creepage distance, designed for signal isolation applications. It is RoHS compliant and halogen-free, ensuring environmental safety standards are met.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Utilizes an NPN phototransistor for reliable signal transmission
- Designed with a compact 4-pin SOP package for space-constrained boards
Applications
- Signal isolation in general-purpose electronic circuits
- Interface between microcontrollers and high-voltage loads
- Switching applications requiring galvanic isolation
Procurement Notes
Verify the specific suffix (e.g., -G) to confirm RoHS compliance status as indicated in official documentation. Confirm availability through authorized distributors, as some variants may have restricted supply or be marked obsolete. Ensure the packaging type matches production requirements.
Selection Notes
Select this component when 5000 Vrms isolation is required in a small footprint. The NPN phototransistor output suits digital switching interfaces. Verify that the input current requirements align with the driving circuit capabilities and that the SOP package fits the PCB layout constraints.
Part Context
This part belongs to the EL1017 family of transistor output optocouplers from Everlight. These devices are widely used for isolating low-voltage control signals from higher-voltage power stages. The family offers various packaging and compliance options to suit different manufacturing and regulatory needs.
Replacement Considerations
Check for direct substitutes like EL1017(TA)-VG or EL1012(TA)-G if pinout and isolation ratings match. Verify that alternative parts maintain the same NPN output type and 5000 Vrms isolation capability before substitution.
