MA5KP8.5AE3

MA5KP8.5AE3 is a type of Transient Voltage Suppression (TVS) Diode. They are used primarily to protect sensitive electronic parts and components from exposure to sharp spikes of voltage or transient voltage. In common usage, the device operates as a unidirectional protection device, similar to an avalanche diode, which, when triggered, will ‘silently’ draw down high voltage pulses to safe levels.

The MA5KP8.5AE3 is a TVS diode designed for high power applications where the maximum possible pulse current over an extended time period needs to be controlled. It can handle a wide range of input voltage ranges, from 6 volts up to 30 volts. It also has a wide reverse breakdown voltage range of 5.5 to 8.5 volts which allows it to efficiently absorb transients and prevent excessive current from entering the protected circuits.

The MA5KP8.5AE3 uses a dual-polarity connection to trigger the SHOCK function which will activate the breakdown voltage of the device. This aids with improved protection since the device can handle both positive and negative voltage spikes, ensuring that all aspects of the voltage transient are properly absorbed.

One of the primary applications for the MA5KP8.5AE3 is in automotive power systems. This device is used to protect the electronics of a car from voltage spikes and other power surges that may occur. It is typically integrated into the vehicle’s main power bus and works to protect the sensitive components from the damaging effects of the transient voltages. It can be used in both direct current and alternating current systems, as well as in both high and low voltage systems.

The working principle of the MA5KP8.5AE3 is based on the P-N junction. When an over-voltage is applied to the anode of the device a reversing bias is created across the junction which causes the electrons from the cathode side of the junction to flow towards the anode. When the voltage reaches a certain point the electrons begin to avalanche causing the device to break down. This causes the device to conduct current and thus absorb some of the energy from the transient voltage.

The MA5KP8.5AE3 is a reliable, fast-acting and efficient TVS diode which is well-suited for use in a variety of automotive applications. Its dual-polarity connection and wide input voltage range help to ensure that the device will provide adequate protection for sensitive electronic components and systems from damaging transient voltage spikes.
