EL1012(TB)-V

Overview

The EL1012(TB)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features an NPN phototransistor output and provides electrical isolation with an insulation voltage of 5000 Vrms. The component is housed in a 4-pin SOP package with long creepage distance, designated by the (TB) suffix. It is designed for applications requiring reliable signal transmission across isolated circuits.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Utilizes an NPN phototransistor for signal output
• Features a 4-pin SOP package with extended creepage distance

Applications

• Precision sensing systems
• Measurement equipment
• Industrial control circuits

Procurement Notes

Verify the specific (TB) suffix to confirm the long creepage SOP package variant. Ensure compatibility with moisture sensitivity levels if storage conditions are uncontrolled. Confirm that the 5000 Vrms isolation rating meets the safety requirements of the target application environment before integration.

Selection Notes

Select this component when high isolation voltage is required in a compact surface-mount form factor. The long creepage design enhances reliability in high-noise or high-voltage environments. Compare against standard SOP optocouplers if enhanced insulation performance is critical for the system design.

Part Context

This part belongs to the EL1012 family of transistor output optocouplers from Everlight. Variants such as EL1012(TA)-G and EL1012(TA)-VG share similar core functionalities but differ in packaging specifications. The (TB) designation specifically indicates the long creepage SOP package configuration.

Replacement Considerations

Direct substitutes include other EL1012 variants like EL1012(TA)-G, provided the package and creepage requirements align. Verify pinout compatibility and isolation voltage ratings when considering alternative manufacturers' equivalents.
