OPIA4N35ATRE

Overview

The OPIA4N35ATRE is a single-channel transistor output optocoupler manufactured by TT Electronics/Optek Technology. It features an NPN phototransistor output with a base terminal for enhanced switching control. The device provides 5000 Vrms isolation voltage between input and output circuits. It operates within a temperature range of -55°C to +125°C and dissipates up to 300 mW of power. The component is housed in a surface-mount 6-SMD package, specifically designed for through-hole or board mounting applications requiring high-voltage isolation.

Feature Summary

• Provides 5000 Vrms electrical isolation for signal transmission across potential barriers
• Integrates an NPN phototransistor with a dedicated base terminal for improved switching performance
• Supports operation in extreme ambient temperatures ranging from -55°C to +125°C

Applications

• Industrial automation systems requiring galvanic isolation
• Solid-state relay driver circuits
• Microcontroller interface modules for high-voltage protection

Procurement Notes

Verify the specific suffix and tape/reel packaging configuration against official datasheets before ordering. Confirm RoHS compliance status and lead times directly with authorized distributors, as this part may be subject to availability constraints. Ensure the selected variant matches the required pinout and isolation ratings for the target design.

Selection Notes

Select this component when high isolation voltage and fast switching are required in a compact surface-mount form factor. The integrated base allows for better control over saturation and storage time compared to standard phototransistors. Consider thermal dissipation limits and operating temperature ranges during circuit layout to ensure reliable long-term performance.

Part Context

This device belongs to the Optek transistor output optocoupler family, designed for general-purpose isolation applications. It complements other variants in the series that may offer different isolation levels or package types. The inclusion of a base terminal distinguishes it from basic phototransistor outputs, offering designers additional flexibility in circuit optimization.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by comparing pinouts, isolation ratings, and current transfer ratios with alternative components from the same manufacturer or other suppliers.
