Description and Introduction

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors **Introduction to the P4SMA16CA TVS Diode from LITTELFUSE**  

The **P4SMA16CA** is a surface-mount **Transient Voltage Suppression (TVS) diode** designed to protect sensitive electronic circuits from voltage transients, electrostatic discharge (ESD), and other electrical surges. Manufactured by **LITTELFUSE**, this component is part of the **P4SMA series**, known for its robust performance in safeguarding power and signal lines.  

With a **standoff voltage of 16V** and a **breakdown voltage ranging from 17.8V to 19.7V**, the P4SMA16CA offers reliable clamping during overvoltage events. It features a **peak pulse power dissipation of 400W (10/1000μs waveform)** and a low clamping voltage, ensuring minimal stress on protected circuits.  

The device is housed in a **DO-214AC (SMA) package**, making it suitable for space-constrained applications. Its bidirectional configuration allows it to suppress both positive and negative transient voltages, enhancing versatility in DC power lines and communication interfaces.  

Common applications include **consumer electronics, industrial controls, automotive systems, and telecommunications equipment**, where transient protection is critical. The P4SMA16CA meets industry standards for reliability and performance, making it a trusted choice for engineers seeking robust circuit protection solutions.  

For detailed specifications, refer to the official datasheet to ensure proper integration into your design.

Application Scenarios & Design Considerations

Alternative Part Number

  • SMAJ16CA --: Same SMA package, 400W bidirectional TVS with 16V standoff voltage, direct functional equivalent.
  • SMBJ16CA --: Bidirectional 16V TVS in SMB package with higher 600W surge rating, suitable drop-in upgrade where board space allows.
  • 1SMA16CAT3G --: SMA-packaged 400W bidirectional TVS with 16V standoff, comparable clamping performance and widely available.
  • SMAJ16CA --: Same SMA package bidirectional 16V TVS diode with comparable clamping voltage and power rating, widely available and pin-compatible.
  • SMBJ16CA --: Bidirectional 16V TVS in SMB package offering higher surge power margin; usable if board space allows the slightly larger footprint.
  • 1SMA16CAT3G --: SMA-packaged bidirectional 16V TVS with similar electrical characteristics, suitable drop-in replacement from a major supplier.
  • SMAJ16CA --: Same SMA package bidirectional 16V TVS diode with comparable clamping voltage and power rating, direct functional drop-in.
  • SMBJ16CA --: Bidirectional 16V TVS in SMB package with higher 600W surge rating, suitable if slightly larger footprint is acceptable.
  • 1SMA16CAT3G --: Alternative vendor SMA bidirectional 16V TVS diode with similar electrical characteristics for cross-vendor sourcing.
