VOH1016AD

Overview

The VOH1016AD is a high-speed optocoupler manufactured by Vishay Semiconductor Opto Division. It features a single channel with a phototransistor output and operates at a data rate of 1 Mb/s, supporting up to 2 MHz NRZ. The device provides 5000 Vrms insulation voltage and includes Schmitt trigger input for noise immunity. Key electrical parameters include a forward current of 4 mA, forward voltage of 1.1 V, rise time of 50 ns, and fall time of 40 ns. It supports an output current of 50 mA with power dissipation of 250 mW. Operating temperature ranges from -40°C to +100°C.

Feature Summary

• Integrates Schmitt trigger input to eliminate oscillation and latch-up issues during signal transitions.
• Provides high common-mode transient immunity (CMTI) of 10 kV/µs for reliable operation in noisy environments.
• Supports isolated level shifting across different voltage domains due to wide power supply range.

Applications

• Isolated digital communication interfaces
• Microcontroller input isolation
• Industrial control systems requiring noise immunity

Procurement Notes

Verify the specific suffix and package type against the official datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status and operating temperature range specifications before integration. Cross-reference manufacturer part numbers with distributor listings to avoid counterfeit components. Ensure proper handling procedures are followed for ESD-sensitive devices during assembly.

Selection Notes

Select this component when high-speed digital isolation with built-in noise filtering is required. The integrated Schmitt trigger simplifies circuit design by removing external hysteresis components. Consider the 5000 Vrms isolation rating for safety-critical applications. Evaluate the 2 MHz NRZ capability if higher data throughput than standard 1 Mb/s is needed within the same package constraints.

Part Context

This device belongs to Vishay's high-speed optocoupler family designed for robust digital isolation. It shares functional similarities with the VOH1016AB and VOH1016AG models, differing primarily in packaging and minor electrical characteristics. The series emphasizes reliability in industrial and automotive environments through enhanced CMTI and latch-up protection.

Replacement Considerations

Direct substitutes include VOH1016AB and VOH1016AG, which share identical electrical performance but differ in package style. Verify pinout compatibility and thermal characteristics when swapping between SMD and DIP variants. Ensure replacement parts meet the same isolation voltage and speed requirements.
