Overview
The EL1018(TB) is a single-channel phototransistor output optocoupler manufactured by Everlight Electronics. It features an infrared emitting diode coupled to an NPN silicon phototransistor within a compact 4-pin SOP package with long creepage distance. Key electrical specifications include a collector-emitter voltage of 80 V, a forward current of 60 mA, and a high isolation voltage of 5000 Vrms. The device operates within a temperature range of -55°C to 110°C and has a power dissipation rating of 250 mW.
Feature Summary
- High isolation voltage capability between input and output circuits
- Compact surface-mount SOP-4 package design with extended creepage distance
- NPN phototransistor output configuration for digital signal isolation
Applications
- Signal isolation in microprocessor systems
- Switching power supply feedback loops
- Solid-state relay driver circuits
Procurement Notes
Verify the specific suffix (TB vs TA) against the Bill of Materials, as it denotes internal binning or testing variations rather than functional differences. Confirm RoHS compliance status via the latest manufacturer datasheet revision. Ensure the SOP-4 footprint matches the PCB layout dimensions precisely. Check for halogen-free certification if required by environmental regulations.
Selection Notes
Select this component when high isolation voltage is required in a small form factor. The NPN output is suitable for sinking current applications. Consider the 80V collector voltage limit for load compatibility. The wide operating temperature range supports industrial environments. Verify that the CTR requirements align with the driving circuit capabilities.
Part Context
This part belongs to the EL1018 family of general-purpose optocouplers. The EL1018 series is widely used for basic isolation tasks. The TB suffix typically indicates specific Current Transfer Ratio (CTR) bins or testing conditions defined by Everlight. It serves as a cost-effective solution for isolating low-power control signals from higher voltage loads.
Replacement Considerations
Direct pin-compatible replacements may include other generic 4-pin transistor-output optocouplers such as PC817 or ILD200, provided isolation voltage and CTR specifications are met. Verify package dimensions and creepage distances carefully. Functional equivalence depends on matching electrical parameters rather than exact model substitution.
