Product Description
Littelfuse SMAJ58A is a high-performance 1-element uni-directional transient voltage suppression (TVS) diode designed for protecting sensitive electronic components from voltage spikes and electrostatic discharge (ESD). This diode is rated for 400 W peak pulse power dissipation, making it suitable for demanding industrial, automotive, and telecommunications applications.
The device features a compact surface mount DO-214 package with a 2-pin configuration that eases integration into modern printed circuit boards (PCBs). With a minimum breakdown voltage of 64.4 V and a maximum reverse stand-off voltage of 58 V, it provides robust protection while maintaining minimal leakage currents of just 1 μA.
Engineered to operate reliably across a wide temperature range from -65 °C to 150 °C, the SMAJ58A diode ensures durability in harsh environments. It supports a maximum peak pulse current of 4.3 A and clamps voltage surges at 93.6 V, protecting circuits from damage due to transient events.
This TVS diode is ideal for industrial control panels, power supplies, telecommunications equipment, and automotive electronics where transient suppression is critical. The product is RoHS compliant, ensuring environmentally responsible manufacturing.
Protects against voltage transients and ESD events effectively. Compact 2-pin surface mount package simplifies PCB layout. Wide operational temperature range enhances versatility. Low leakage current reduces power consumption and heat.
