TVS (Transient Voltage Suppressor) diodes provide protection to delicate electronic circuits from the damage caused by electrical transients, or brief "spikes" of high-voltage electricity. The PGSMAJ20A series of TVS diodes is a particularly ideal choice for a wide range of applications, with a variety of features to meet the needs of many electronics designs.

In today’s electronic devices, transient voltages can be caused by various actions of nature, including lightning, EMP, ESD, and over-voltage. In these cases, extremely high voltages can cause destruction of the electronic components. The PGSMAJ20A series of TVS diodes protect against these transients before they can cause any damage.

The PGSMAJ20A diode is a low-capacitance, low-leakage diode that provides high surge capability. This makes the diode suitable for protecting various circuits, including but not limited to: automotive clocks, solutions for USB and I2C interfaces, analog-to-digital converters, and powerful computers.

The PGSMAJ20A’s low capacitance and high surge protection provide excellent protection to sensitive circuits. Its ESD protection also helps the device to meet the UL1449 4th edition standards. The diode is available in a variety of packages including: TSOP, SOT-23, 8-pin CSP packages and SMAJ20A surface mount packages.

The PGSMAJ20A is designed to provide an exceptionally high surge capability in a small package, making it ideal for applications where space may be limited. In terms of its operating environment, the diode is well-suited for use in a wide range of temperatures, including -55 to 125 ℃, and offers excellent ESD protection.

The working principle of the PGSMAJ20A series is similar to other TVS diodes. It works by providing a path for the over-voltage current to safely flow away from the circuit, rather than damaging it. The diode will signal the microcontroller when the voltage is too high, so that the microcontroller can redirect the current to a safer circuit or a diode junction to prevent further damage.

Overall, the PGSMAJ20A series of TVS diodes provides excellent protection for sensitive circuits in automotive, industrial, medical and consumer electronics applications. It does so at an incredibly small size, further enabling electronics designers to create devices that are even more compact and powerful.
