Description and Introduction

UNI-DIRECTIONAL GLASS PASSIVATED JUNCTION TRANSIENT VOLTAGE SUPPRESSOR 600 WATTS, 6.8 THRU 200 VOLTS The **P6SMB39A** from FAQOR is a surface-mount transient voltage suppressor (TVS) diode designed to protect sensitive electronic circuits from voltage spikes and transient events. This component is part of the **P6SMB series**, known for its robust surge-handling capabilities and fast response time, making it ideal for applications in power supplies, communication systems, and industrial electronics.  

With a **standoff voltage of 39V** and a **breakdown voltage range of 43.2V to 47.8V**, the P6SMB39A offers reliable clamping performance against overvoltage conditions. Its **peak pulse power dissipation of 600W (10/1000μs)** ensures effective suppression of high-energy transients, safeguarding downstream components. The device features a low clamping voltage, minimizing stress on protected circuits while maintaining high surge robustness.  

Encased in a **DO-214AA (SMB) package**, the P6SMB39A is compact and suitable for automated assembly processes. Its **bidirectional configuration** allows for versatile use in both AC and DC circuits. Engineers often integrate this TVS diode into designs requiring ESD protection, surge mitigation, or compliance with transient immunity standards.  

For applications demanding reliable overvoltage protection in a space-efficient form factor, the P6SMB39A presents a practical solution backed by proven performance.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • SMBJ39A --: Same SMB (DO-214AA) package, 39V standoff unidirectional TVS diode with comparable clamping voltage and power rating, widely available and pin-compatible.
  • 1SMB39AT3G --: SMB-packaged 39V unidirectional transient voltage suppressor with similar surge capability, a common drop-in replacement from a major supplier.
  • P6SMB39A-E3/52 --: Equivalent 600W 39V unidirectional TVS in SMB package from Vishay; note the different series prefix makes it distinguishable, though verify exact suffix ordering availability.
  • SMBJ39A --: Same SMB (DO-214AA) package, 39V standoff unidirectional TVS with similar 600W peak pulse power rating; widely available and a direct functional substitute.
  • 1SMB39AT3G --: SMB-packaged 39V unidirectional TVS diode with comparable clamping and power ratings, suitable drop-in replacement for transient suppression.
  • SMAJ39A --: 39V unidirectional TVS in SMA package with similar electrical characteristics; slightly smaller package but usable where board space allows and 400W rating is sufficient.
