【導(dǎo)讀】針對負(fù)載突降導(dǎo)致的瞬態(tài)和其它瞬態(tài)電壓情況,Littelfuse TPSMA6L系列瞬態(tài)電壓抑制(TVS)二極管能夠為敏感電子元件提供二次瞬態(tài)電壓保護(hù)。 這款SMA設(shè)備的小尺寸DO-221AC封裝高度不足1.1毫米,但是能夠提供與標(biāo)準(zhǔn)SMB設(shè)備相同的額定脈沖峰值功率耗損(PPPM),即600W。 TPSMA6L系列盡管尺寸小巧,卻能夠提供優(yōu)越的電氣性能,因此使設(shè)計師在升級電路保護(hù)的同時無需更改現(xiàn)有設(shè)計尺寸或針對新電路布局提供更強保護(hù)。

Littelfusehas 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-Q101qualified, which is a critical consideration for automakers because components that meet this specification are suitable for use in the harsh automotive environmentwithout additional component level qualification testing.”
 
More AEC-Q101 qualified automotive TVS protection products will be available after Q1, 2013.
