TVS diodes, or transient voltage suppressors, are designed for protecting sensitive electrical components from destructive voltage transients, which are surges in voltage significantly above normal. The 1KSMB22CAHM4G is a type of TVS diode specifically designed to protect circuit boards from damaging surge voltages. This article will explain the application field and working principle of the 1KSMB22CAHM4G.

Application Field of 1KSMB22CAHM4G

The 1KSMB22CAHM4G is designed to protect low-voltage circuits from high voltage transients. The maximum surge voltage of the 1KSMB22CAHM4G is 22 V, with a peak pulse current of 18 A. This makes it ideal for protecting sensitive communication systems, such as computers, communications systems, and internal control systems. It is commonly used in military and aerospace applications, as well as medical and instrumentation systems.

Working Principle of 1KSMB22CAHM4G

The 1KSMB22CAHM4G is a Zener diode designed to absorb high voltage transients. The diode is made up of two p-type and two n-type layers, which form a PN junction. When a high voltage transient is present, the diode will conduct and divert the current away from the protected circuit. This prevents the sensitive components in the circuit from being damaged by the large amount of energy in the transient.

The 1KSMB22CAHM4G is designed to absorb up to 18 A of peak pulse current without being damaged itself. After the transient is over, the diode will block the current and return to its original state. This allows the protected circuit to remain unaffected by the transient.

Conclusion

In conclusion, the 1KSMB22CAHM4G is a type of TVS diode designed to protect low-voltage circuits from high voltage transients. It is commonly used in military and aerospace applications, as well as medical and instrumentation systems. The diode is designed to absorb up to 18 A of peak pulse current without being damaged, and after the transient is over, the diode will block the current and return to its original state. This ensures that sensitive components in the protected circuit are not damaged by the surge.
