MA5KP48A

TVS (Transient Voltage Suppressors) diodes are designed to protect sensitive electronic components from transient voltage events such as electrostatic discharge, voltage spikes, and lightning strikes. They are an important element in the modern electronic circuit protection landscape and continue to evolve to meet the demands of the ever-changing technology environment. The MA5KP48A is a double-diode TVS diode from Littelfuse, designed to protect sensitive electronics from transients in automotive, industrial, and consumer applications.

MA5KP48A features a 5-kelvin peak pulse power rating and a breakdown voltage of 48 volts. The diode features low clamping voltage, <3-volt threshold voltage, and low dynamic resistance (<0.5-ohm) for excellent clamping performance. In addition, the diode features an internal shield for improved ESD immunity, and a lightning pulse protection of up to 40 kA.

One of the main applications of the MA5KP48A series is the protection of power converters and motors from transient voltage events due to their low clamping voltage, low dynamic resistance, and excellent ESD immunity. With its 5-K peak pulse power rating, this series is well suited for protecting more power-sensitive electronics from power surge events. The low threshold voltage and low dynamic resistance also enables it to be used in consumer and automotive applications as a transmitter protection diode. The MA5KP48A is also well suited for use as a protection circuit for Ethernet or USB ports.

When it comes to the actual working of the MA5KP48A, it is quite similar to the traditional TVS diodes. Whenever a surge occurs, and the voltage exceeds the threshold voltage of the device, a current will flow through the diode, thus clamping the voltage. This clamping action will reduce the voltage level and limit the current flow, thus protecting the device. This series of TVS diodes, however, features an internal shield, which provides improved ESD immunity. This means that the diode can more effectively suppress transient voltage events with improved response time.

In conclusion, the MA5KP48A is a double-diode TVS diode from Littelfuse, designed to protect sensitive electronics from transients in automotive, industrial, and consumer applications. This series of diodes features a 5-kelvin peak pulse power rating, a breakdown voltage of 48 volts, low clamping voltage, and low dynamic resistance, making it an ideal choice for power converters, motors, and consumer and automotive applications. The device also features an internal shield for improved ESD immunity, and a lightning pulse protection of up to 40 kA. Overall, the MA5KP48A is an excellent choice for a wide range of device protection applications.
