VOH1016AG

Overview

The VOH1016AG is a high-speed optocoupler manufactured by Vishay Semiconductor Opto Division. It features a single channel with a phototransistor output and operates at data rates up to 2 MHz (NRZ). The device provides 5000 Vrms isolation voltage and includes Schmitt trigger input circuitry for noise immunity. Key electrical parameters include a forward current of 4 mA, forward voltage of 1.1 V, rise time of 50 ns, fall time of 40 ns, reverse voltage of 6 V, output current of 50 mA, and power dissipation of 250 mW. It functions within a temperature range of -40°C to +100°C and is housed in a DIP-6 package.

Feature Summary

• High data rate capability up to 2 MHz (NRZ) for fast signal transmission
• Integrated Schmitt trigger input ensures latch-up and oscillation-free operation
• Provides robust galvanic isolation with 5000 Vrms insulation voltage
• Wide power supply range supports isolated level shifting across different voltage domains

Applications

• RS-232 bus system optical isolation
• Isolated level shifting between different voltage domains
• Digital communication interfaces requiring high common mode transient immunity

Procurement Notes

Verify the specific suffix designation when ordering, as variations such as VOH1016AG-V may indicate different packaging or minor specification adjustments compared to the standard VOH1016AG. Confirm RoHS compliance status through official datasheets or manufacturer documentation prior to final procurement decisions. Ensure compatibility with existing DIP-6 footprint requirements in the target design.

Selection Notes

Select this component for applications demanding high-speed digital isolation with noise immunity. The integrated Schmitt trigger makes it suitable for noisy environments where clean logic transitions are critical. Consider the 5000 Vrms isolation rating for safety-critical systems. Verify that the 2 MHz data rate meets the system's bandwidth requirements and that the DIP-6 package fits the available board space.

Part Context

The VOH1016AG belongs to Vishay's high-speed optocoupler family, designed for reliable digital signal transmission across isolated barriers. It shares core performance characteristics with related models like the VOH1016AB and VOH1016AD, differing primarily in pinout configuration or packaging options. This series addresses the need for compact, high-performance isolation in modern electronic designs.

Replacement Considerations

Direct substitutes within the same Vishay series include VOH1016AB and VOH1016AD. Verify pin compatibility and package dimensions before substitution. Other manufacturers' high-speed optocouplers with similar isolation ratings and data rates may serve as alternatives if pinouts match.
