Transient Voltage Suppressor (TVS) diodes are a type of semiconductor device used to protect sensitive semiconductor circuits from electrical overstress (EOS) that can occur due to a sudden increase in the voltage that is applied to the device’s input. The MAP4KE39AE3 is a diode specifically designed to protect automotive systems from short-term spikes in voltage. This diode is designed to clamp the input voltage at a safe level and protect system components from electrical stress that can be caused by such spikes.

The MAP4KE39AE3 has a maximum breakdown voltage of 39 volts and a maximum clamping voltage of 50.5 volts. It has a maximum power dissipation rating of 250mW with a maximum pulsed current rating of 27.3A. The diode is available in a SOD-323 package size, which is a 0.1” leaded discrete SMD package. The device has an operating temperature range of -55°C to +125°C.

The application field for the MAP4KE39AE3 diode is in automotive applications that require a short-term voltage spike protection for integrated circuits. These systems typically require protection from electro-static discharge (ESD) and from load dump. An example of a system that this diode would be used in is an electrical powertrain system, which requires protection from both ESD and load dump.

The working principle behind the MAP4KE39AE3 involves using the diode to act as a voltage clamp. When a voltage spike occurs, the diode acts as a short-circuit and the voltage is then clamped until the spike dissipates. The voltage is held safely at a level below the breakdown voltage of the diode and hence the components of the system are protected from the overvoltage.

The MAP4KE39AE3 offers excellent protection against load dump and ESD and provides a superior clamping performance compared to other similar devices. It is an ideal device for use in automotive applications that require short-term voltage spike protection.
