Low Profile 600W TVS Diode from Littelfuse Protects Sensitive Electronics from Voltage Transients
Press release date: January 24, 2013
CHICAGO, — 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 (PPPM) 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 testing.”
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 (PPPM) 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
