Transient voltage suppressor diodes (TVS) are an important component in the electronic market, capable of protecting delicate circuits. SMAJ16A-TP devices are a special type of TVS diodes designed for transient voltage suppressance in sensitive applications.These unidirectional devices are non-polarized and fabricated in a specialized SMAJ series. Designed to prevent highly transient voltage pulses from damaging sensitive circuits, this device offers excellent current and clamping capability.

Application Field

SMAJ16A-TP devices are used widely in the electronics industry due to their high performance. They are most commonly used in the telecommunications and automotive fields. The devices have a breakdown voltage of 16 volts and are able to withstand transient voltage pulses up to 600 volts. The SMAJ16A-TP devices can be used as supplements in the automotive industry, as they can provide protection against high voltage transients due to load dump events. Similarly, telecommunications systems utilize these devices to protect against ac line transients due to lightning.

Working Principle

These TVS diodes operate by clamping the supply voltage to a predetermined voltage (VD). Once the current through the device reaches a high enough level, the zener diode will turn on, effectively clamping the incoming voltage to the breakdown voltage of the device (VBR). This helps reduce the transient voltage, allowing the downstream components to remain within the voltage and current limits. When the transient voltage increases, the current through the device increases as well. This increase in current is limited, as it is now flowing through the zener diode breakdown region. This limits the amount of voltage available, thus helping to protect the downstream components from excessively high voltage transients.

SMAJ16A-TP devices offer optimal protection in a variety of applications due to their fast response time, excellent clamping capabilities, and wide operating temperature range. While their protection level will depend on the application and the external components used, these devices are ideal for protecting sensitive electronics against transient voltage pulses.
