TVS - Diodes: PACDN042Y3R Application Field and Working Principle

A transient voltage surge suppressor, or TVS diode, is an electronic component used to absorb transient voltage surge spikes present in the primary power supply or output of a power source, providing protection from over-voltage conditions on equipment and devices. The PACDN042Y3R is a unidirectional axial leaded TVS diode, designed to protect against Electro Magnetic Interference / Radio Frequency Interference (EMI/RFI) and lightning-induced voltage transients.

Principle of Operation

The PACDN042Y3R is a diode-based protection device which operates by conducting stored electrical energy during a surge event, offering circuit protection from a destructive transient. Its full unidirectional capabilities allow it to be used for ESD protection and negative pulse protection. Whenever over-voltage or high current flows back into the circuit, the diode triggers and draws the current away from the port, thus preventing any damage.

Application Field

The PACDN042Y3R is used for protecting a wide variety of electronic products and systems, including consumer electronics, communication networks, motor drives, automotive, sensors, industrial and medical applications.The PACDN042Y3R is an ideal choice for protection against power supply surges, ESD, transients, and electrostatic discharges. It provides excellent protection against Electro Magnetic Interference / Radio Frequency Interference (EMI/RFI) and lightning-induced voltage transients. This device has excellent transient performance in surges up to 420V and can be used up to 6kV in surge life applications.The PACDN042Y3R provides superior over-voltage protection, low clamping voltage and fast turn-on time with low capacitance and low leakage current. Its bidirectional capability allows it to be used for both over-voltage and under-voltage protection. Additionally, the device has low leakage current over temperature and features a high current carrying capacity.
