Description and Introduction

400W Zener Suppressor The **1SMA54AT3** from ON Semiconductor is a high-performance **surface-mount TVS (Transient Voltage Suppressor) diode** designed to protect sensitive electronic circuits from voltage transients and electrostatic discharge (ESD). This component is part of the **SMA series**, known for its robust surge-handling capabilities and fast response time.  

With a **standoff voltage of 54V** and a **breakdown voltage ranging from 60V to 66.5V**, the 1SMA54AT3 effectively clamps transient voltages, safeguarding downstream components. It offers a **peak pulse power dissipation of 400W** (10/1000μs waveform) and features a low clamping voltage, ensuring reliable protection in demanding environments.  

The **unidirectional** configuration of the 1SMA54AT3 makes it ideal for DC applications where transient suppression is required in one polarity. Its compact **SMA (DO-214AC) package** allows for easy integration into space-constrained PCB designs while maintaining high thermal efficiency.  

Common applications include **power supplies, communication systems, automotive electronics, and industrial controls**, where protection against voltage spikes is critical. The 1SMA54AT3 meets industry standards for reliability and performance, making it a trusted choice for engineers seeking robust transient voltage protection.  

By combining high surge capability with a compact form factor, this TVS diode ensures enhanced circuit durability without compromising design flexibility.
