SMAJ13A-TR Transient Voltage Suppressor Diode from STMicroelectronics
The SMAJ13A-TR is a robust and highly efficient Transient Voltage Suppressor (TVS) diode designed by STMicroelectronics. This protective component is engineered to safeguard sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. The SMAJ13A-TR is an ideal choice for a wide range of applications where reliability and stability are paramount.
Constructed with STMicroelectronics' state-of-the-art technology, the SMAJ13A-TR TVS diode is housed in a compact SMA (DO-214AC) package, which not only saves valuable board space but also ensures ease of implementation in various circuit designs. Its small footprint is complemented by its high surge capability, making it an excellent choice for space-constrained applications that require robust protection against voltage spikes.
The SMAJ13A-TR offers a stand-off voltage of 13V, which means it maintains a high impedance state until the threshold voltage is exceeded. Upon reaching the breakdown voltage, the diode switches to a low impedance state, clamping the transient voltage and shunting excess current away from the sensitive components it is designed to protect. It has a peak pulse power dissipation of 400W for a 10/1000μs waveform, which allows it to handle significant power surges without performance degradation.
With its fast response time, the SMAJ13A-TR reacts almost instantaneously to transient voltage spikes, ensuring that the connected devices are shielded effectively. The diode's bidirectional design provides symmetrical protection, making it suitable for AC applications or where the polarity of the transient could be either positive or negative.
The SMAJ13A-TR is also characterized by its low incremental surge resistance and excellent clamping capability, which further contributes to its effectiveness in protecting electronic circuits. Designed to meet IEC 61000-4-2 and IEC 61000-4-5 standards, this TVS diode is a reliable choice for applications such as telecommunications systems, computer interfaces, industrial equipment, and consumer electronics that require high-level protection against voltage transients.
In summary, the SMAJ13A-TR from STMicroelectronics is a high-quality, versatile component that offers superior transient voltage suppression capabilities, ensuring the safety and longevity of electronic systems in a variety of demanding environments.
