A TVS diode (transient voltage suppression diode) is a type of diode used to protect sensitive electronic equipment from voltage transients generated by lightning and other electrical fast transients. TVS diodes are typically used in the automotive industry, aerospace industry, telecom industry, and medical devices.This article will discuss the 1KSMB27CA M4G application field and working principle and how it applies to TVS diodes.The 1KSMB27CA M4G is a TVS diode designed to protect sensitive components from transient voltages caused by lightning and other transient voltages. The diode\'s operating voltage range is from 100V to 27V, with an operating current of 0.1A in any of its three configurations: bidirectional, unidirectional, and grounding.The 1KSMB27CA M4G has a breakdown voltage of 27V and a peak pulse current of 3.75A. The diode is designed to suppress transients in two ways: clamping and shunt. Clamping is the ability of the diode to limit the voltage, while shunt is the ability of the diode to reduce the voltage.When the 1KSMB27CA M4G is connected in a bidirectional configuration, it will clamp positive and negative transients. The clamping level is determined by the surge protection device (TVS diode). If the incoming transient voltage exceeds the breakdown voltage of the diode, a voltage clamping action will occur. The surge voltage will be limited at the voltage rating of the diode; thus, preventing the surge from reaching the components downstream.The 1KSMB27CA M4G is also capable of shunt protection. When connected in a unidirectional circuit, the 1KSMB27CA M4G will shunt away transients in order to protect sensitive components. The voltage is reduced across the diode when a transient occurs, thus protecting the components downstream.To summarize, the 1KSMB27CA M4G is a TVS diode designed to protect sensitive electronic components from transient voltages. The 1KSMB27CA M4G can be connected in either a bidirectional or unidirectional configuration to provide clamping or shunt protection respectively. The 1KSMB27CA M4G has a breakdown voltage of 27V and a peak pulse current of 3.75A. The 1KSMB27CA M4G is commonly used in the automotive, aerospace, telecom, and medical industries.
