VOH1016AB-T

Overview

The VOH1016AB-T is a high-speed optocoupler manufactured by Vishay Semiconductor Opto Division. It features a single channel with an open collector phototransistor output and operates at data rates up to 2 MHz (NRZ). The device provides 5000 Vrms isolation voltage and supports a supply voltage of 16V. Key electrical parameters include a forward current of 50 mA, a forward voltage of 1.1 V, and a power dissipation of 250 mW. It is housed in a 6-SMD Gull Wing package and functions within a temperature range of -40°C to +100°C.

Feature Summary

• High data rate capability up to 2 MHz (NRZ) for fast signal transmission
• Latch-up and oscillation-free operation ensures stable performance
• Low turn-on threshold current of 2 mA for efficient drive requirements
• Logic-compatible output design simplifies interface integration

Applications

• RS-232 bus system optical isolation
• General-purpose digital signal isolation
• Microcontroller input/output isolation

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Ensure the 6-SMD Gull Wing package matches your PCB footprint requirements. Check for any regional certification marks such as VDE if required for your application safety standards.

Selection Notes

Select this component when high-speed digital isolation is required with low input current thresholds. The open collector output suits applications needing pull-up resistor configuration. Compare against standard logic outputs if direct driving is necessary without external components. Consider the 5000 Vrms isolation rating for noise immunity in industrial environments.

Part Context

This part belongs to Vishay's high-speed optocoupler family designed for robust digital communication interfaces. It complements other models like the VOH1016AG which offers DIP packaging. The series emphasizes reliability in noisy environments while maintaining compact surface-mount form factors suitable for modern electronics manufacturing.

Replacement Considerations

Direct substitutes may include other Vishay VOH series parts with similar pinouts and electrical characteristics. Verify compatibility regarding isolation voltage ratings and data speed specifications before substitution. Ensure replacement parts maintain the same package type to avoid PCB redesign efforts.
