新品TVS二极管,封装高度不足1.1毫米

发布时间:2013-01-29 责任编辑:alexwang

【导读】针对负载突降导致的瞬态和其它瞬态电压情况,Littelfuse TPSMA6L系列瞬态电压抑制(TVS)二极管能够为敏感电子元件提供二次瞬态电压保护。 这款SMA设备的小尺寸DO-221AC封装高度不足1.1毫米,但是能够提供与标准SMB设备相同的额定脉冲峰值功率耗损(PPPM),即600W。 TPSMA6L系列尽管尺寸小巧,却能够提供优越的电气性能,因此使设计师在升级电路保护的同时无需更改现有设计尺寸或针对新电路布局提供更强保护。

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.
