Overview
The EL1017(TB) is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output and provides high isolation voltage between input and output circuits. The device is housed in a compact 4-pin SOP package with tape and reel packaging options, including Cut Tape and MouseReel formats. It is RoHS compliant and designed for applications requiring electrical isolation.
Feature Summary
- Provides high isolation voltage between input and output circuits
- Features a compact dual-in-line or SOP package design
- Includes UL recognition and VDE approval certifications
Applications
- General purpose signal isolation
- Switching power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix requirements for your application, as variations such as TA or VG exist within the EL1017 family. Confirm that the TB suffix aligns with your preferred packaging format, typically tape and reel. Ensure compliance with current RoHS directives and check for any regional distribution restrictions before finalizing procurement plans.
Selection Notes
Select this component when a standard transistor output optocoupler with 5000Vrms isolation is required. Consider the SOP package for space-constrained PCB layouts. Verify that the NPN phototransistor output characteristics match your load requirements. Check if alternative suffixes like TA are needed for specific surface-mount reflow profiles.
Part Context
This part belongs to the EL1017 series of photocouplers from Everlight. The series includes variants with different lead spacing and mounting configurations. The EL1017(TB) specifically denotes the SOP package version with tape and reel packaging, distinguishing it from DIP versions like the EL817.
Replacement Considerations
Direct substitutes include other 4-pin SOP transistor output optocouplers with similar isolation ratings. Verify pinout compatibility and CTR specifications against alternatives. Cross-reference with EL1017 variants having different suffixes if packaging needs change.
