MPLAD30KP130A/TR Circuit Protection

MPLAD30KP130A/TR is typically used in a variety of applications such as PLC (programmable logic controllers), access control systems, automation applications, telephone/video communication systems, signal transmission systems, and portable/mobile devices. It is also frequently used in systems where harsh environment conditions require high levels of reliability. The device offers excellent ESD (electrostatic discharge) protection and uses avalanche breakdown for maximum speed of response. This makes it suitable for applications in which matching of rise and fall times of the ESD protection is critical. MPLAD30KP130A/TR is typically used in applications that require wide temperature ranges (-55°C to +150°C) and high surge current ratings (up to 17A peak). The device features a low thermal resistance and can be connected either parallel or in series to meet different voltage requirements.

The MPLAD30KP130A/TR is an unidirectional silicon avalanche diode designed to protect integrated circuits from electrostatic discharge (ESD) and transient overvoltage caused by lightning strikes. The diode is very fast responding and is ideal for use in high-isolation ESD protection circuits. The device features a wide operating temperature range of -55°C to +150°C and is able to handle overvoltage events up to 17A peak. The device works by creating a low resistance path for high voltage overshoot during transient events. This quickly relays the surge to ground while clamping the voltage of the protected device. The diode then returns to its normal state and resumes protection after the transient event is over. The device is also able to tolerate momentary overvoltage up to 4.2kV, which makes it suitable for use in high-voltage circuits.
