Description and Introduction

ARK Electronics - Surface Mount Transient Voltage Suppressors Peak Pulse Power 400W Breakdown Voltage 6.8 to 550V **Introduction to the P4SMA220A TVS Diode from Vishay**  

The **P4SMA220A** is a surface-mount **Transient Voltage Suppression (TVS) diode** manufactured by **Vishay**, designed to protect sensitive electronic circuits from voltage transients and electrostatic discharge (ESD). This bidirectional diode offers robust clamping performance, making it suitable for applications requiring reliable overvoltage protection.  

With a **standoff voltage of 220V** and a **peak pulse power rating of 400W (10/1000μs)**, the P4SMA220A efficiently suppresses high-energy surges. Its fast response time ensures minimal voltage overshoot, safeguarding components in power supplies, communication systems, and industrial electronics.  

The **SMA (DO-214AC) package** provides a compact footprint, ideal for space-constrained designs while maintaining high thermal efficiency. The device meets industry standards for reliability, including **AEC-Q101 qualification** for automotive applications, ensuring performance in harsh environments.  

Key features include **low leakage current** and **high surge capability**, making it a dependable choice for surge protection in AC/DC lines, data lines, and other high-voltage circuits. Whether used in consumer electronics, automotive systems, or industrial controls, the P4SMA220A delivers robust transient protection with minimal impact on system performance.  

For engineers seeking a high-performance TVS diode, the **P4SMA220A** offers a balance of power handling, compact size, and reliability.

Alternative Part Number

  • SMAJ220A --: Same SMA package unidirectional TVS diode with 220V standoff voltage and comparable clamping performance; widely available alternative.
  • SMBJ220A --: Unidirectional TVS diode with matching 220V standoff voltage; SMB package offers higher surge rating and is a common cross-reference.
  • 1SMA220A --: SMA-packaged unidirectional TVS diode with 220V standoff voltage, electrically similar and suitable drop-in replacement.
  • SMAJ220A --: Same SMA package unidirectional TVS with 220V standoff voltage and similar clamping, widely available from a major brand.
  • SMBJ220A --: Equivalent 220V unidirectional TVS in SMB package offering higher surge rating; can replace SMA part where board space allows.
  • 1SMA220A --: SMA-packaged 220V unidirectional TVS with comparable electrical characteristics and a different series naming.
