TVS (Transient Voltage Suppressors)-Diodes are a type of semiconductor device which is used for protecting against high surge voltages. The 3KASMC24AHE3_B/I is one such device and is particularly suitable for high current applications and harsh environmental conditions. This paper will discuss the application field and working principle of the 3KASMC24AHE3_B/I.

The 3KASMC24AHE3_B/I is a bidirectional dual chip transient voltage suppressor diode that has a breakdown voltage of 24 V. It has an operating temperature range of - 40 ˚C to 85 ˚C and has a typical clamping voltage of 42.2 V. The diode has a peak current capacity of 8 A, a maximum power dissipation of 150 mW, and a maximum surge current of 32 A. The diode is housed in an 8 Pin SOT-223 package type and is Lead (Pb)-free for RoHS compliance.

The 3KASMC24AHE3_B/I is mainly used for the protection of components from voltage transients generated by power related discharges such as lightning strikes, electrostatic discharges, and inductive switching. The device is designed to clamp transient voltages to a safe level which is below the device\'s Peak Pulse Power dissipation rating. If an overvoltage occurs due to some external source, the diode will start conducting current and limit the voltage. The diode can protect a wide range of devices like I/O ports, voltage regulator, power transistors, etc., by providing voltage surge protection.

The 3KASMC24AHE3_B/I utilizes a unique bidirectional configuration which allows the device to effectively suppress transients in both directions. This eliminates the need for two devices in order to provide protection from both positive and negative transients. The diode has a low dynamic resistance which helps to reduce clamping time and helps to keep voltage levels and transients in very tight limits.

As for the working principle of the 3KASMC24AHE3_B/I, it is based on the Avalanche Breakdown Principle. Under normal conditions, the diode acts as an open switch, which is a blocked state. If the voltage applied to the diode exceeds the breakdown voltage (Vbd), the diode will enter its conductive state, delivering a large current to the circuit by allowing electrons to avalanche across the junction. This current surge is limited to the device\'s Peak Pulse Power dissipation (Ppp). After the current surge, the diode will return to its blocked state.

The 3KASMC24AHE3_B/I is an ideal choice for applications that require protection from high surge voltages in demanding environments. It has a low dynamic resistance which helps to reduce clamping time and keep voltage levels and transients in tight limits. The device offers excellent protection from various power-related discharges like lightning strikes, electrostatic discharges, and inductive switching. The bidirectional configuration eliminates the need for two devices and provides protection from both positive and negative transients.
