Diodes Incorporated SMAJ120A-13-F TVS Diode

The SMAJ120A-13-F from Diodes Incorporated is a robust transient voltage suppressor (TVS) diode designed to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. This TVS diode is a favored choice for a wide range of applications, including consumer electronics, industrial systems, and automotive circuits, where reliable protection against voltage spikes is critical.

With its SMA (DO-214AC) package, the SMAJ120A-13-F offers a compact footprint that is suitable for high-density circuit board designs. It is capable of handling pulses as defined by the IEC 61000-4-5 standard, providing a peak pulse power dissipation of 400W for 10/1000μs waveforms. This ensures that devices are shielded from sudden surges in power, maintaining the integrity and longevity of the electronic components.

The SMAJ120A-13-F features a stand-off voltage of 120V, which is the maximum voltage that the diode can withstand without conducting significant current. Its breakdown voltage ranges from 133V to 147V, offering a margin of safety above the stand-off voltage to accommodate voltage spikes. The clamping voltage, which is the maximum voltage drop across the diode during a surge event, is specified at 193V for this component, ensuring that the protected circuitry is not exposed to damaging voltage levels.

This TVS diode is also characterized by its fast response time, typically in the order of picoseconds, which means it can react almost instantaneously to transient events, providing immediate protection to the connected devices. The SMAJ120A-13-F is also compliant with RoHS and REACH environmental standards, making it a suitable choice for use in green and sustainable technology designs.

In summary, the SMAJ120A-13-F from Diodes Incorporated is a high-quality, surface-mount TVS diode that offers excellent transient voltage suppression capabilities. Its small size, high surge capability, and fast response time make it an ideal solution for protecting sensitive electronics from voltage spikes and surges in a variety of applications.
