TVS (Transient Voltage Suppressor) diodes are designed to provide electrical protection from electrostatic discharges, inductive load switching, lightning and other forms of transient voltage. The MAP5KE22A is a unidirectional diode specifically designed for effective protection against transients in automotive environments. It was developed to protect against transients in excess of 5 kilovolts and 22 amperes.

MAP5KE22A’s use a silicon avalanche junction design to ensure maximum transient absorption and reliable protection. It has an easy-to-mount SOT669 (SC-59) package and its surface mounted design reduces the circuit board space required. It’s bidirectional and can provide protection regardless of polarity.

MAP5KE22A is used in a wide range of automotive environments. It’s typically used to protect electronic circuits from transients due to inductive load switching and power-on surge. It’s also used to protect against electrostatic discharges (ESD), surge protection in power bus systems, battery protection, and protection from lightning.

The working principle of MAP5KE22A is quite simple. When a transient voltage is applied, the diodes avalanche breakdown voltage is reached, thus initiating an avalanche current which is then rapidly inverted into heat, dissipating the energy of the transient. The device has a positive temperature coefficient that ensures stablility and a low dynamic resistance allowing for lower device clamping voltage.

MAP5KE22A also exhibits excellent surge performance characteristics. It has an avalanche energy rating of 64mJ, a high peak pulse power of 16kW and a peak pulse current of 22A. It has a nominal breakdown voltage of 5kV, a forward voltage of 1.2V at 25°C, and a thermal resistance rating of 65 ̊C/W.

MAP5KE22A is an effective protection device in automotive environment when dealing with transients. Its easy-to-mount package and reliable protection makes it a useful tool for protecting various electrical components. Its high peak power and current rating combined with its low dynamic resistance allows for a stable protection solution and its excellent surge performance makes it an ideal choice for automotive applications.
