Wurth Elektronik 1-Element Uni-Directional TVS Diode, 400 W, 2-Pin DO-214 824500301 / SMAJ30A

Wurth Elektronik 824500301 / SMAJ30A is a 1-element uni-directional Transient Voltage Suppressor (TVS) diode designed for industrial and electronic protection applications. It offers a robust 400 W peak pulse power dissipation rating suitable for defending circuits against voltage spikes and transient surges. The diode has a low profile DO-214 surface mount package with 2 pins, making it ideal for modern PCB assembly where space efficiency is critical.

This TVS diode features a single diode configuration with a uni-directional voltage suppression capability, delivering a minimum breakdown voltage of 35.05 volts and a clamping voltage of 48.4 volts. It ensures fast response times through a glass passivated junction and exhibits a very low leakage current of 1 microampere, maintaining circuit efficiency.

The device operates reliably under a wide temperature range from -65°C up to 150°C, making it suitable for harsh environmental conditions often encountered in industrial, automotive, and commercial electronics applications. The maximum peak pulse current rating is 40 amperes, allowing it to absorb large transient surges and safeguard connection points, power supplies, and sensitive semiconductor devices.

Its compact dimensions of 4.24 mm length, 2.67 mm width, and 2.14 mm height make it practical for dense circuit designs. The TVS diode series WE-TVSP from Wurth Elektronik ensures compliance with modern electronic standards while offering durable and high-quality performance.
