CHICAGO -- January 24, 2013

Littelfuse, Inc., the global leader in circuit protection, has introduced the
TPSMA6L Series of Transient Voltage Suppression (TVS) Diodes. This new series
can provide secondary transient voltage protection from transients induced by
load dump and other transient voltage events for automotive electronic control
units, sensors, entertainment systems, and other applications that require
high reliability. This SMA device’s low profile DO-221AC package is less than
1.1 mm high, but it offers the same peak pulse power dissipation (P[PPM])
rating (600W) as standard SMB devices. The TPSMA6L Series offers superior
electrical performance in a small footprint package, allowing designers to
upgrade their circuit protection without altering their existing design
footprint or provide more robust protection in new circuit layouts.

“The TPSMA6L Series’ low-profile, small-footprint design and 600W rating make
these TVS diodes a great solution for secondary protection in high
reliability, automotive, and portable device applications,” said Charlie Cai,
Global Product Manager for Littelfuse TPSMA6L product line. “They are also
AEC-Q101 qualified, which is a critical consideration for automakers because
components that meet this specification are suitable for use in the harsh
automotive environment without additional component level qualification

More AEC-Q101 qualified automotive TVS protection products will be available
after Q1, 2013.

The TPSMA6L Series TVS Diode offers these key features and benefits:


  *600W peak pulse power dissipation (P[PPM]) rating
  *Low profile (less than 1 mm) surface mount package (DO-221AC) and small
    footprint design
  *AEC-Q101 qualified
  *Compliant with IEC 61000-4-2 and IEC 61000-4-4 standards


  *Provides same power rating as a standard SMB device
  *Compatible with standard SMA and SMB devices
  *Suitable for use in harsh automotive environments
  *Provides superior surge and ESD protection
