ST’s transient voltage suppressors (TVS) are made to resist the stress levels specified in standards such as IEC 61000-4-x to meet all application requirements. Able to withstand 10/1000 µs transient voltage surges and with power capability at 175 °C, they fit tough environments thanks to low power derating at high temperature. Manufactured on ST’s upgraded production lines using robust and well-known silicon die leads to improve reliability for your applications.

Applications such as SMPS or drones are getting smaller and smaller. SMA4F and SMA6F keep the 400 and 600 W power capability of the well-known families SMAJ, SMBJ, SMA6T and SM6T with the advantage to be in a thin package of 1 mm versus 2.3 mm.

Key features

  • 5 to 33 V range unidirectional
  • 400 W or 600 W in SMA size package 
  • Footprint compatible with SMA, SMB 
  • Industrial & automotive grade 
  • TJ (max.) = 175 °C

Key benefits

  • Increased power density 
  • Lower cost per watt ratio 
  • Thinner package for slim applications
  • No PCB redesign thanks to backward footprint compatibility with all standard SMD packages on the market. 
  • Unchanged electrical parameters, also when moving from SMBJ to SMA6F 
  • Better availability
  • Cost effetcive solution ot SMA/SMB market solutions
  • Wettable flank (Automatic Optical Inspection compatible)
