【应用】汽车级TVS管UAT4P系列,用于车载供电系统的抛负载保护,能抗350ms脉冲功率
在汽车电子系统上,由于不同原因造成各种的脉冲中,抛负载是常见而且也是危害比较大的一种现象。所谓抛负载,就是当汽车引擎正在运转,发电机正向汽车的电源线输送电流时,如果电池突然断开,就会产生较高的浪涌电压。其特点是浪涌电压高、脉冲宽度宽、持续时间长,如果不加以有效防护,会对后极电路产生致命的损坏。
如图1所示,就是对抛负载保护原理的直观的模拟,即通过在电源上并专用的抛负载保护 TVS实现。如果不对电路做出相应的防浪涌整改,很容易造成电路回路中的电子器件因过压导致损坏。由于抛负载的浪涌最大脉宽一般在350-400ms左右,同时对应脉冲峰值电压也比较高,12V系统最大高达87V左右,24V系统最大高达174V左右,所以市场上常见TVS(只能抗10/1000us的瞬间脉冲)不能满足其保护要求,需要在电源端口并联一颗针对抛负载保护的专用TVS,其能抗宽脉冲浪涌(350毫秒的脉宽),功率也比较大且满足车规要求。
图1
针对以上抛负载保护需求,电安科技推出单双向、宽脉冲功率、车规级TVS UAT4P系列。其应用优势如下:
1、专门针对抛负载保护的设计,能抗350ms脉冲功率,插件P600封装,功率6600W;
2、有单/双向产品可供选择,满足不同电路应用需求;
3、峰值电流高,最高可达204A,耐冲击能力更强;
4、具有漏电流小,响应时间快等优点,同时满足AEC-Q101认证要求;
5、国产器件,交期价格有优势;
