VOH1016AB-T2

Overview

The VOH1016AB-T2 is a high-speed optocoupler from Vishay Semiconductor Opto Division, housed in a 6-SMD package. It features a single channel with a phototransistor output and operates at data rates up to 1 Mb/s or 2 MHz (NRZ). The device provides robust electrical isolation with an insulation voltage of 5000 Vrms and a common mode transient immunity of 10 kV/µs. Key electrical parameters include a forward current of 4 mA, forward voltage of 1.1 V, reverse voltage of 6 V, and output current of 50 mA. Power dissipation is rated at 250 mW, with rise and fall times of 50 ns and 40 ns respectively. Operating temperature ranges from -40°C to +100°C.

Feature Summary

• Integrates a high-efficiency input LED coupled with an optical photodiode IC detector for enhanced signal integrity.
• Features Schmitt trigger logic compatibility to ensure latch-up and oscillation-free operation.
• Provides high common mode transient immunity to maintain performance in noisy environments.

Applications

• RS-232 bus system isolation
• Digital isolator circuits requiring high noise immunity
• Industrial communication interfaces

Procurement Notes

Verify the specific suffix 'T2' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the 6-SMD footprint matches the target PCB layout dimensions. Ensure compliance with RoHS directives if applicable to the final product regulations. Cross-reference the manufacturer part number against official Vishay documentation to validate the exact pinout and electrical characteristics before integration.

Selection Notes

Select this component when high-speed digital isolation is required alongside strong noise immunity. The integrated Schmitt trigger makes it suitable for applications where signal shaping is necessary to prevent false triggering. Consider the 5000 Vrms isolation rating for safety-critical designs. The SMD package facilitates surface-mount assembly, while the 2 MHz data rate supports faster communication protocols compared to standard optocouplers.

Part Context

This device belongs to the VOH1016 series of high-speed optocouplers designed for demanding industrial and commercial applications. The series emphasizes reliability through latch-up free operation and high CMTI. The T2 suffix typically denotes a specific reel packaging option for mass production. Vishay utilizes advanced semiconductor processes to achieve the balance between speed and isolation strength in this compact form factor.

Replacement Considerations

Direct substitutes within the same family include VOH1016AB-VT2 and VOH1016AD. Verify pin compatibility and electrical specifications before swapping. Other Vishay models like VOH1016AG offer similar performance in DIP packages but require different mounting considerations.
