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

STMicroelectronics SMAJ48A-TR is a robust 1-element uni-directional transient voltage suppressor (TVS) diode designed to protect electronic circuits from voltage transient events such as electrostatic discharge or inductive load switching. This diode supports peak pulse power dissipation of 400 W, enabling it to handle high energy surges and protect sensitive devices effectively.

The device features a minimum breakdown voltage of 53.3 V and a maximum reverse stand-off voltage of 48 V. The clamping voltage is specified at 100 V, allowing rapid response to voltage spikes by limiting voltage to safe levels. Its low maximum reverse leakage current of 200 nA ensures minimal power loss during normal operation.

The SMAJ48A-TR comes in a compact DO-214 surface mount package with 2 pins, facilitating easy integration on printed circuit boards (PCBs) in industrial, automotive, and consumer electronics applications. It operates reliably from -55°C up to 150°C, making it suitable for harsh environments.

Its maximum peak pulse current of 23 A ensures effective clamping during transient conditions with a test current of 1 mA specifying its operational testing parameters. The single-element per chip design allows precise and reliable transient voltage suppression.

With dimensions of 4.6 mm length, 2.95 mm width, and 2.03 mm height, this diode fits compact designs requiring strong electrostatic discharge protection. The TVS Diode is a critical component in electronic component protection used broadly in semiconductor, electronic components, power & connectors industries.
