TVS diodes, or transient voltage suppression diodes, are widely used in the industry to protect against transients, or spikes of electrical energy, caused by events like lightning strikes. These devices are simple and effective, able to quickly clamp down on high voltage levels, ensuring that the sensitive downstream circuitry remains protected. The MASMBJ20AE3 is representative of these devices, offering unidirectional protection against transients up to 20Amps.

This specific device is designed for surface mount assembly, allowing it to quickly and easily be integrated into sophisticated circuitry designs. The MASMBJ20AE3 features low capacitance of about 0.25pF, making it ideal for applications wherein high frequencies need to be routed and are susceptible to damage from fast transients. In many of these applications, the MASMBJ20AE3 can reduce EMI noise below FCC compliance by as much as 30dB, allowing designers to maintain the highest levels of signal integrity .

The MASMBJ20AE3 is an excellent choice for applications where reliability and speed are both critical. Once draped across a circuit, it acts like an electrostatic shield, absorbing high-frequency shocks that could otherwise cause irreversible damage. Because the MASMBJ20AE3 is so fast, it can prevent transients from having any significant impact on the device or system it is protecting.

In addition to being fast, the MASMBJ20AE3 is also highly robust. It is rated at 20Amps, with a maximum peak pulse current of 200Amps, and a breakdown voltage of 15V. The device is constructed with a molded plastic outer shell, and features a quad design, which provides two sets of protection for surge events. Coupled with its low capacitance, this makes the MASMBJ20AE3 highly suited for high-speed applications where a rapid response to transients is vital.

The MASMBJ20AE3 is a great choice for numerous applications, from consumer electronics to automotive systems. This unidirectional TVS diode has a low capacitance and an extremely fast response time, making it highly reliable. It is an excellent choice for any system where sensitive circuitry must be protected from high-frequency transients.
