Overview

The ESDA6V1L is a dual-channel unidirectional TVS diode array housed in a standard SOT-23-3L package. It is designed to protect sensitive equipment against electrostatic discharge (ESD) and peak pulse power events up to 300W at 8/20 microseconds. With a minimum breakdown voltage of 6.1V and low leakage current, it is an efficient solution for protecting 5V logic lines.

Why Choose This Part

This device offers a high ESD protection level of up to 30 kV and can handle peak pulse currents of 18A. Its low leakage current of 20uA and high integration of two diodes in a single SOT-23 package reduce component count and PCB area while maintaining robust protection.

Applications

Microcontroller Input Protection
Protects GPIO pins on MCUs from transient spikes and ESD events on external user interfaces.
5V Power Rail Clamping
Provides a 5.25V reverse standoff voltage suitable for clamping surges on regulated 5V power supply rails.
High-Density Logic Boards
Utilizes the small SOT-23 footprint to provide dual-line protection in space-constrained PCB layouts.
Keypad and Pushbutton ESD
Clamps high-voltage discharge from human interface components to prevent damage to internal logic.

Getting Started

When integrating the ESDA6V1L, place the component as close as possible to the connector or ESD source to minimize trace inductance. Ensure the ground pin is connected to a solid ground plane with short, wide traces to effectively shunt transients away from sensitive ICs.
