Overview

The VO14642AT is a high-speed, SPST-NO (1 Form A) solid-state relay designed for efficient AC/DC switching. It features a photo-coupled architecture that provides high isolation and clean, bounce-free performance in a standard 6-DIP package. This relay is capable of handling load currents up to 1 A (or 2 A in DC-only mode) with a maximum load voltage of 60 V.

Why Choose This Part

The VO14642AT offers high-speed switching and a very low maximum on-state resistance of 250 mOhms, minimizing power dissipation in high-current applications. Its TTL/CMOS compatible input allows it to be driven directly by microcontrollers with just 1.3 VDC input voltage. Furthermore, its solid-state construction ensures a much longer operating life than mechanical relays by eliminating contact pitting and mechanical fatigue.

Applications

Industrial Control Systems
Used for driving solenoid valves and small actuators where bounce-free switching is critical for system longevity.
Automatic Test Equipment (ATE)
Ideal for high-speed signal routing and measurement switching due to its low 250 mOhm on-state resistance.
Security and Alarm Systems
Provides silent, reliable switching for sensor loops and alert indicators without the mechanical wear of traditional relays.
Instrumentation Front-Ends
Used in data acquisition systems to provide galvanic isolation between sensitive digital logic and external analog signals.

Getting Started

To integrate the VO14642AT, design a current-limiting resistor for the input LED side to ensure the forward current stays within specifications, typically targeting the 1.3 VDC nominal drop. For DC-only operation, pins 4, 5, and 6 can be configured in parallel to increase the load current capacity to 2 A. Ensure proper PCB layout clearance between the input and output pins to maintain the isolation voltage rating.
