TVS (Transient Voltage Suppressor) Diodes

Transient Voltage Suppressor (TVS) diodes are an important tool used in the protection of electrical systems, said to be particularly useful in industries ranging from automotive to consumer electronics. TVS devices are designed to protect electronic components from damages due to Electrostatic Discharge (ESD) which is caused when an electrical charge builds up quickly and discharges, disrupting the function of the components, including permanent damages. This is why TVS diodes are so important - they provide a sort of \'electrical buffer\' between the component they are protecting and the unexpected voltage of the ESD. The PGSMAJ16CAHR3G is one such device.

Application field & Working Principle of PGSMAJ16CAHR3G

The PGSMAJ16CAHR3G is a 16V bidirectional Transient Voltage Suppressor designed to protect against ESD, and is typically used in portable electronic devices and automotive microelectronics applications. It offers a high level of protection from ESD, with a low dynamic resistance, low leakage current and fast response time to disturbances. It can ideally be used in applications where fast response times and enhanced levels of protection are crucial, such as automotive and military communication systems.

The PGSMAJ16CAHR3G is also designed to be bidirectional, which means it is able to reduce the voltage transition both directions, from high to low and from low to high. In normal operation, it acts like a simple resistive element, with a small amount of current flowing through it. When a negative voltage transient is applied to the PGSMAJ16CAHR3G, it begins to conduct, and this increases the current flow until it reaches the clamping voltage. This reduces the voltage transition and ensures minimal disruption to the connected system.

The PGSMAJ16CAHR3G is also designed to be RoHS compliant, and it meets the AEC-Q101 standard requirements. It has a maximum break down voltage of 16V, a peak pulse power of 1000W, a peak pulse current of 40A, a clamping voltage of 27V, a capacitance of 5pF and an operating temperature range of -55 °C to 150 °C. All this makes it ideally suited for applications in ultra-low power consumer electronics and automotive microelectronics.

Conclusion

The PGSMAJ16CAHR3G is a 16V bidirectional Transient Voltage Suppressor that is designed to offer enhanced levels of protection from Electrostatic Discharge in consumer electronics and automotive microelectronic applications. It has a low dynamic resistance, a low leakage current, and a fast response time to disturbances, all of which make it uniquely suitable for applications where fast response and protection from ESD is required.
