Product Description
STMicroelectronics SMAJ33A-TR is a 1-element uni-directional Transient Voltage Suppressor (TVS) diode designed for protecting sensitive electronic circuits against transient voltage spikes. It features a surface mount DO-214 package with two pins, making it ideal for compact PCB layouts and automated assembly.
This device offers a peak pulse power dissipation of 400 W with excellent transient voltage clamping capabilities. The minimum breakdown voltage is 36.7 V and the maximum reverse stand-off voltage is 33 V, providing robust protection for components against overvoltage conditions. The clamping voltage is 69.7 V, which limits transient voltages to protect downstream semiconductor devices.
Designed to operate under harsh environmental conditions, the SMAJ33A-TR supports a wide operating temperature range from -55°C to 150°C. The device also has a maximum peak pulse current rating of 33 A, allowing it to absorb high energy transient surges.
The diode features low maximum reverse leakage current of 200 nA ensuring minimal power loss during normal operation. Its compact physical dimensions of 4.6 mm length, 2.95 mm width, and 2.03 mm height allow high-density circuit design. The surface mount DO-214 package facilitates easy integration into automated manufacturing environments.
Applications include transient voltage protection in industrial electronics, consumer electronics, automotive electrical systems, and telecommunications equipment. The SMAJ33A-TR provides efficient ESD protection and enhances device reliability against voltage transients.
