FOD070LR2

Overview

The onsemi FOD070LR2 is a single-channel high-speed optocoupler housed in an 8-SOIC package. It features a Darlington transistor output with base control, providing 2500 Vrms isolation voltage. The device supports a data rate of 1 Mb/s and operates within a temperature range of -40°C to +85°C. Key electrical parameters include a forward current of 16 mA, a typical forward voltage of 1.45 V, and a maximum power dissipation of 100 mW. The output type is configured as a phototransistor with base connection, suitable for logic interface applications requiring galvanic isolation.

Feature Summary

• Integrates a Darlington output stage with dedicated base control pin for enhanced switching speed and noise immunity
• Provides robust 2500 Vrms insulation barrier between input and output circuits for safety compliance
• Delivers high current transfer ratio characteristics suitable for driving low-current loads directly

Applications

• Industrial communication bus isolation
• Logic-level signal interfacing in noisy environments
• Power supply feedback loop isolation

Procurement Notes

Verify the specific suffix 'R2' corresponds to the reel packaging configuration required for your assembly line. Confirm that the 8-SOIC narrow body dimensions match your PCB footprint design. Ensure the 2500 Vrms isolation rating meets the safety standards applicable to your final equipment classification. Cross-reference the RoHS status with environmental regulations for your target market before placing orders.

Selection Notes

Select this component when a high current transfer ratio is needed without external pull-up resistors. The integrated base control allows for faster turn-off times compared to standard phototransistors. Consider the 1 Mb/s data rate limit for signal integrity requirements. Evaluate the 8-SOIC package size against available board space constraints relative to wider SOIC options.

Part Context

This part belongs to the FOD070L series of high-speed optocouplers from onsemi. It shares the same internal architecture as other variants in the family but differs in packaging and tape-and-reel specifications. The series is designed for applications requiring reliable digital signal transmission across isolated boundaries with minimal propagation delay.
