SMA6L Series SMA TVS Diode

The Littelfuse SMA6L series TVS diodes are ideal for applications such as battery chargers, industrial equipment, and switch-mode power supplies

Image of Littelfuse's SMA6L Series Low-Profile 600 W SMA TVS DiodeThe SMA6L Series, an addition to the Littelfuse SMA family of TVS diodes, is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. The SMA6L series can handle the same level of power as a standard Littelfuse SMB series TVS diode (600 W) when operated within its peak pulse power rating. The low-profile SMA package provides the same surge capability as the industrial standard SMB but with the lowest height profile (1.1 mm vs. 2 mm) available in the industry. This small form factor makes the SMA6L series TVS diode ideal for use in applications such as ultra-slim notebook computers, hard disk drives, telecom equipment, battery chargers, industrial equipment and switch mode power supplies.


  • SMA low profile package: less than 1.1 mm
  • Same power as standard SMB devices (600 W)
  • Footprint compatibility with standard SMA and SMB products
  • Typical failure mode is short from over-specified voltage or current
  • Low inductance, excellent clamping capability
  • Fast response time: typically less than 1.0 ns from 0 V to VBR min
  • High temperature soldering: 260°C/40 seconds at terminals
  • Built-in strain relief
  • Glass passivated junction
  • Typical IR less than 1 µA above 12 V
  • Matte tin lead–free plated
  • Halogen-free and RoHS compliant
