Description and Introduction

BI-DIRECTIONAL GLASS PASSIVATED JUNCTION TRANSIENT VOLTAGE SUPPRESSOR 600 WATTS, 6.8 THRU 200 VOLTS # Introduction to the P6SMB6.8CA TVS Diode  

The **P6SMB6.8CA** is a surface-mount **transient voltage suppressor (TVS) diode** designed to protect sensitive electronic circuits from voltage spikes and electrostatic discharge (ESD). Manufactured by **FD (First Semiconductor)**, this component is part of the **P6SMB series**, offering robust surge protection in a compact **SMB (DO-214AA) package**.  

With a **standoff voltage of 6.8V** and a **breakdown voltage range of 7.5V to 8.4V**, the P6SMB6.8CA is optimized for low-voltage applications, such as **data lines, power supplies, and communication interfaces**. It features a **bidirectional configuration**, making it suitable for both positive and negative transient suppression.  

Key specifications include a **peak pulse power dissipation of 600W (10/1000μs waveform)** and a low clamping voltage, ensuring effective protection while minimizing stress on downstream components. Its fast response time helps divert transient surges before they can damage sensitive circuitry.  

Ideal for **automotive, industrial, and consumer electronics**, the P6SMB6.8CA provides reliable overvoltage protection in a cost-effective, space-saving form factor. Engineers often select this diode for its balance of performance, durability, and compliance with industry standards.  

For detailed application guidelines, refer to the manufacturer’s datasheet for precise electrical characteristics and layout recommendations.

Application Scenarios & Design Considerations

BI-DIRECTIONAL GLASS PASSIVATED JUNCTION TRANSIENT VOLTAGE SUPPRESSOR 600 WATTS, 6.8 THRU 200 VOLTS

Alternative Part Number

  • SMBJ6.8CA --: Same SMB (DO-214AA) package, 600W bidirectional TVS with 6.8V standoff, direct functional equivalent from a different series.
  • 1SMB6.8CA --: 600W bidirectional TVS in SMB package with matching 6.8V standoff voltage, widely available alternative.
  • SMAJ6.8CA --: Bidirectional 400W TVS in SMA package with same 6.8V standoff; lower power rating but usable in many clamping applications.
  • SMBJ6.8CA --: Same SMB (DO-214AA) package bidirectional TVS diode with matching 6.8V standoff voltage and comparable clamping performance; widely available and a direct drop-in replacement.
  • P6SMB6.8CA-E3/52 --: Vishay's P6SMB series bidirectional TVS in SMB package with identical 6.8V working voltage and 600W peak pulse rating; different manufacturer series naming makes it easy to distinguish.
  • 1SMB6.8CA --: Bidirectional 600W TVS diode in SMB package with 6.8V standoff voltage; different prefix/series from the source and electrically equivalent for most surge protection applications.
  • SMBJ6.8CA --: Same SMB (DO-214AA) package bidirectional TVS with 6.8V standoff, directly interchangeable in most designs.
  • 1SMB6.8CA --: Bidirectional 6.8V TVS in SMB package from a different series, electrically equivalent and widely available.
  • P6SMB6.8CA-E3 --: Vishay's P6SMB series bidirectional 6.8V TVS in SMB package, same ratings and footprint as the original.
