Description and Introduction

400 Watt Unidirectional Transient Voltage Suppresor **Introduction to the P4SMA18A from VISHAY**  

The P4SMA18A is a high-performance surface-mount transient voltage suppressor (TVS) diode designed to protect sensitive electronic circuits from voltage spikes and transients. Manufactured by VISHAY, this component offers reliable clamping performance with a standoff voltage of 18V and a peak pulse power dissipation of 400W (10/1000μs).  

Featuring a compact SMA (DO-214AC) package, the P4SMA18A is ideal for space-constrained applications, including telecommunications, industrial controls, and consumer electronics. Its low clamping voltage ensures robust protection against electrostatic discharge (ESD), lightning-induced surges, and other transient events.  

Key specifications include a reverse standoff voltage of 18V, a breakdown voltage range of 20.0V to 22.1V, and a fast response time, making it suitable for high-speed data lines and power supply protection. The diode’s bidirectional configuration allows it to handle both positive and negative transient voltages efficiently.  

Engineers value the P4SMA18A for its durability, consistent performance, and compliance with industry standards. Whether used in automotive systems, power management circuits, or portable devices, this TVS diode provides a dependable safeguard against electrical overstress, enhancing system reliability.  

For detailed application guidance, consult the datasheet to ensure proper integration in circuit designs.
