Product Description

Taiwan Semiconductor SMAJ45CA R3 is a 1-element bi-directional transient voltage suppressor (TVS) diode with a peak pulse power dissipation of 400 W, specifically designed for surface mount applications in a 2-pin DO-214 package.

This device provides robust ESD protection and transient voltage suppression in electronic circuits, helping prevent damage from voltage spikes. The bi-directional configuration makes it highly suitable for AC and DC voltage transient protection.

The diode features a minimum breakdown voltage (Vbr) of 50 V and can withstand up to 45 V maximum reverse stand-off voltage (Vwm). It clamps transient voltages at 72.7 V, while in operation it supports a maximum peak pulse current of 5.5 A, ensuring durability in demanding conditions.

Operating temperature ranges from a minimum of -55°C to a maximum of 150°C, making it suitable for a wide variety of industrial, manufacturing, and electronic equipment environments.

Its compact physical dimensions (length 4.6 mm, width 2.83 mm, height 2.3 mm) facilitate integration into densely packed printed circuit boards. The device exhibits a minimal maximum reverse leakage current of 5 μA to promote energy efficiency and reduce power loss.

The diode is configured as a single element with 2 pins, optimized for surface mount technology (SMT) applications. Typical uses include transient voltage suppression in power supplies, telecommunication systems, and automotive electronics.

TVS diodes like the SMAJ45CA R3 are critical in safeguarding sensitive semiconductor components against voltage spikes and electrostatic discharges. Explore more related TVS Diodes and semiconductor components in EnvMart’s Electronics & Electricals category.
