Description and Introduction

Unidirectional and Bidirectional Transient Voltage Suppressor diodes The **P6SMB400CA** from **VISHAY** is a high-performance **surface-mount transient voltage suppressor (TVS) diode** designed to protect sensitive electronic circuits from voltage spikes and transient events. With a **standoff voltage of 400V** and a **peak pulse power dissipation of 600W**, this component provides robust overvoltage protection in a compact **DO-214AA (SMB) package**.  

Engineered for reliability, the **P6SMB400CA** features a **low clamping voltage**, ensuring fast response times to divert harmful transients away from critical components. Its **bidirectional configuration** makes it suitable for AC or DC applications, including power supplies, telecommunications equipment, and industrial control systems.  

Key specifications include a **breakdown voltage range of 444V to 490V** and an **operating temperature range of -55°C to +150°C**, making it suitable for harsh environments. The device complies with **RoHS standards**, ensuring environmental safety.  

For designers seeking dependable surge protection, the **P6SMB400CA** offers a balance of high power handling and compact form factor, making it an ideal choice for modern electronics requiring robust transient suppression. Its performance and durability align with industry demands for high-reliability circuit protection solutions.

Application Scenarios & Design Considerations

Unidirectional and Bidirectional Transient Voltage Suppressor diodes

Alternative Part Number

  • SMBJ400CA --: Same SMB (DO-214AA) package, 400V bidirectional standoff voltage, 600W peak pulse power; direct functional equivalent from a different series.
  • 1SMB400CA --: 400V bidirectional TVS in SMB package with 600W peak pulse rating, matching the original's clamping and surge capability.
  • P6SMB440CA --: Same 600W SMB bidirectional TVS family with slightly higher 440V standoff, usable where a small voltage margin is acceptable.
  • SMBJ400CA --: Same SMB (DO-214AA) package, 400V bidirectional standoff voltage and similar clamping performance; widely available industry-standard equivalent.
  • 1SMB400CA --: Bidirectional 400V TVS diode in SMB package with comparable peak pulse power and clamping voltage; direct functional replacement.
  • SMAJ400CA --: Bidirectional 400V TVS in SMA package; slightly lower power rating but suitable for many surge protection designs where board space allows.
