Product Description
The Littelfuse SMAJ5.0A is a 1-element, uni-directional transient voltage suppression (TVS) diode designed to protect sensitive electronic circuits from voltage spikes and transient surges. This device is packaged in a compact DO-214 surface mount package with two pins, making it easy to integrate into modern circuit boards.
With a peak pulse power dissipation rating of 400 W, this TVS diode can effectively clamp high energy transients, thereby safeguarding components against damage. It offers a minimum breakdown voltage of 6.4 V and a clamping voltage of 9.2 V, ensuring precise suppression characteristics. The maximum reverse stand-off voltage is 5 V, which prevents unwanted conduction under normal operation.
The device operates reliably across a wide temperature range from -65°C up to 150°C, making it suitable for demanding industrial and automotive environments. The device has a test current rating of 10 mA and can handle a maximum peak pulse current of 43.5 A during surge conditions, demonstrating excellent robustness. It also features ESD protection and maintains a low maximum reverse leakage current of 800 μA, preserving circuit efficiency.
This SMAJ series TVS diode contains a single diode element per chip, providing consistent and repeatable protection performance. The diode's compact physical dimensions of 4.5 mm in length, 2.79 mm in width, and 2.087 mm in height enable flexible PCB layout options.
