STMicroelectronics 1-Element Uni-Directional TVS Diode 400 W, 2-Pin DO-214 SMAJ48A-TR

STMicroelectronics SMAJ48A-TR is a high-performance 1-element uni-directional Transient Voltage Suppressor (TVS) diode designed for protecting sensitive electronic circuits from transient voltage spikes. With a peak pulse power dissipation rating of 400 W, this diode efficiently clamps high-voltage transients, providing robust surge protection in demanding electronic environments.

Manufactured in a compact DO-214 package with 2 pins for surface mounting, this TVS diode offers easy PCB integration, suitable for industrial, consumer electronics, telecommunications, and power supply applications. Its single-element configuration and unidirectional operation ensure effective voltage suppression on one polarity, ideal for unilateral transient suppression needs.

The diode features a minimum breakdown voltage (Vbr) of 53.3 V and a maximum reverse stand-off voltage (Vwm) of 48 V, ensuring protection is activated only above designated voltage thresholds. With a clamping voltage (Vc) of 100 V, the device limits voltage surges effectively. Able to withstand peak pulse currents (Ippm) up to 23 A, the diode maintains performance during transient events.

Designed for operational reliability, the SMAJ48A-TR functions across a temperature range of -55°C to 150°C. It also exhibits a minimal maximum reverse leakage current of 200 nA, contributing to low power dissipation during standby. Although it does not carry an automotive standard certification, it provides ESD protection for enhanced circuit robustness.

The compact physical dimensions of 4.6 mm length, 2.95 mm width, and 2.03 mm height make it suitable for space-constrained electronic applications. Its robust design is especially relevant in industrial, laboratory, telecommunications, power management, and manufacturing sectors where transient suppression is critical.

Overall, the STMicroelectronics SMAJ48A-TR presents a reliable, compact solution for transient voltage suppression, ensuring protection of electronics against voltage spikes and surges to improve device longevity and performance.
