TVS (transient voltage suppressor) diodes are severely underrated components that are responsible for protection from transient, high-voltage surges. In most applications, they are used to protect sensitive semiconductors against power surges, such as those caused by waves, electrostatic discharges or other electrical disturbances. The 1.5KE22ARL type of TVS diode is designed for use in automotive electronics for overvoltage protection and active protective circuits.

The Max. Peak Pulse Power for the 1.5KE22ARL is rated at 1.5kW. The on-state resistance is typically around 0.45Ω during normal operating conditions. This low resistance allows it to pass high currents of up to 22A without damage, which makes it suitable for use in automotive electronics. The diode has a clamping voltage or breakdown voltage of 22V, and can withstand repeated high-voltage pulses up to a maximum of 1500W.

To work, the 1.5KE22ARL needs a protective circuit to divert the surge current away from the sensitive electronic device. The surge current will flow through one or more diodes in the circuit and is limited to the breakdown voltage of the diode. If the breakdown voltage is exceeded, the surge current will be safely diverted away from the protected electronic device. When the surge current is diverted to a safe path, the sensitive electronic device will not be damaged, which makes this type of TVS diode ideal for protecting sensitive automotive electronics.

The 1.5KE22ARL provides an additional advantage of a relatively low clamping voltage. This relatively low clamping voltage of 22V ensures that the sensitive electronic device or automotive electronic devices being protected will not be damaged during prolonged overvoltage conditions.

The 1.5KE22ARL is also used in active protective circuits. These active protective circuits detect any transient voltage rising from any source and provide a direct path to ground in order to protect the sensitive device. The 1.5KE22ARL is rated for up to 1500W, so it can safely and efficiently divert the excess current away from the sensitive device.

In conclusion, the 1.5KE22ARL is an excellent choice for protecting automotive electronics and other sensitive electronic devices from transient, high-voltage pulses. The diode has a maximum peak power rating of 1.5kW and a clamping voltage of 22V, which prevents damage during prolonged overvoltage conditions. The low on-state resistance of 0.45Ω allows for up to 22A to pass through without damage, making it suitable for protecting sensitive semiconductors. The 1.5KE22ARL can also be used in active protective circuits, as it is rated up to 1500W and provides a safe path for excess current.
