【应用】Littelfuse压敏电阻V175SM20用于大功率开关电源作防浪涌保护,钳位电压达455V
某大功率开关电源的电路保护部分原理框图如下,需求MOV(压敏电阻)和TVS(瞬态电压抑制器),应对突发的大电压浪涌,防止其电路中的电子元器产生破坏。
其中,MOV的大致参数要求为要求VRMS参数能达到170V,Vdc能达到220V,功率80J以上,钳位电压450V。据此给客户推荐了LITTELFUSE(力特)的SM20金属氧化物压敏电阻器(MOV)系列。该系列包括一个尼龙模压封装,和焊接到板的折叠镀锡金属引线,SMD系列基于径向20毫米内变阻器元件,特征如下:
直流电压额定值26-420VDC
交流电压额定值20Vac-320AC
85°C环境下性能无降级
无铅、无卤素、符合RoHS标准
适用于汽车卸载能量的低压设备
可采用“华夫饼”托盘封装
该系列的典型电参数如下:
再查如下的选型表,根据客户要求的VRMS参数能达到170V,Vdc能达到220V,功率WTM80J以上,钳位电压VC可达450V,可以很容易的看到V175SM20符合要求。
其中V175SM20的VRMS参数能达到175V,大于要求的170V;Vdc达到了230V,超过要求的220V;功率WTM为90J,大于要求的80J;钳位电压VC达595V,远超要求的450V。因而V175SM20完全满足客户要求,起到很好的防浪涌保护。
