The SMAJ4460CE3/TR13 is a ~600V, 4 Watt, unidirectional Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. It is available in a small SMA package and offers high transient protection, with a low typical stand-off voltage of ~20V, making it an ideal solution for applications where a low clamping voltage is desirable.The SMAJ4460CE3/TR13 is specifically designed for use in applications that require high surge current and low clamping voltage. It can be used in a variety of different applications such as automotive, consumer electronics, industrial, and telecommunications.In automotive applications, the SMAJ4460CE3/TR13 can be used to protect against voltage transients induced by lightning and other sources of electromagnetic interference. It is designed to withstand high inrush currents and transients up to 600V. The low typical stand-off voltage of ~20V makes it well suited for use in circuits with sensitive components, such as microcontrollers.For consumer electronics applications, the SMAJ4460CE3/TR13 can be used to protect against high energy over-voltage transients. It is well suited for use in consumer electronics circuits, such as power supplies and cellular phones, where high transient energy levels are likely to be encountered. The device is able to withstand high inrush currents and transients up to 600V.In industrial applications, the SMAJ4460CE3/TR13 can be used to protect against voltage transients induced by lightning, EMI/RFI, and other sources of over-voltage current. It offers over-voltage protection in applications such as high voltage motors and transformers. The device offers a low standby current, which minimizes power losses in the system.In telecommunications applications, the SMAJ4460CE3/TR13 can be used to protectlines against inductive and capacitive transients. It is designed to withstand high inrush currents and transients up to 600V. The low typical stand-off voltage of ~20V also makes it well suited for use in circuits where high transient energy levels are likely to be encountered.The SMAJ4460CE3/TR13 works on the principle of abrupt voltage clamping, which means that it limits the voltage across the sensing junction to a predetermined level during a transient. The device is constructed from two back-to-back Zener diodes in series, with the junction of the two diodes connected to the two terminals of the device.When a voltage transient above a predetermined threshold is applied to the SMAJ4460CE3/TR13, the avalanche breakdown occurs in one of the diodes and conducts the excess current to the other diode. This clamps the voltage across the sensing junction to a predetermined level. The device is designed to handle transients up to ~600V.The SMAJ4460CE3/TR13 is an ideal solution for applications where a low standby voltage is required, such as automotive, consumer electronics, industrial and telecommunications. It offers superior surge protection up to ~600V and a low typical stand-off voltage of ~20V. The device is constructed from two back-to-back Zener diodes in series, which provides effective over-voltage protection for sensitive components and circuits.
