MALCE100A

Transient Voltage Suppression (TVS) Diodes, also known as suppressor diodes or clamp diodes, are specialized voltage-dependent diodes designed to protect sensitive electronics from voltage transients such as electrostatic discharge (ESD) or power surges. A TVS diode, such as the MALCE100A, is a two-terminal device with a simple construction and a high breakdown voltage. It is used in a wide range of applications for protection against voltage transients, and the following sections discuss its mode of operation and applications.

Mode of Operation

The MALCE100A is a single-line space-grade transient voltage suppressor diode that can be used to protect circuits from transient voltage transients. When reverse biased, the diode has high resistance. When a voltage transient is applied, the current quickly increases, and the diode acts as a short circuit with the current limited by its internal resistance. The diode can absorb large amounts of energy and dissipates the heat generated by the transient voltage through its thermal protection.

When the voltage transient has passed, the diode returns to its high-resistance state. The device is able to protect various types of components from different kinds of voltage transients, including electrostatic discharge, surge, spike, inductive load switching, and 1.2/50µs lightning. The device also offers excellent temperature stability and long-term reliability.

Applications

The MALCE100A is commonly used in the automotive and aerospace industries. It is used to protect various types of electronic components, including microprocessors, FPGAs, motors, and sensors, from a wide range of voltage transients. The device can also be used to protect automotive ECUs from ESD.

The MALCE100A is designed to meet automotive standards, including AECQ100-002/-003, ISO 17544, and MIL-PRF-19500, and it can be used in applications such as Automotive Compliance Testing Devices and engine control modules, as well as on-board aviation systems. The device is also used in applications where high-speed transient protection is required, such as in high-speed data transmission systems. The diode is also used for EMI/RFI suppression applications, such as in power supplies.
