【应用】基于硕凯电子半导体放电管和自恢复保险丝的CAN总线防护方案，可通过10/700μS浪涌测试
汽车上各种电子控制单元的数目不断增加，连接导线显著增加，因浪涌损害的情况加剧。本文将介绍使用硕凯电子的半导体放电管P0300SA、P0300SB、P0300SC和自恢复保险丝JK250-120U设计的CAN总线防护方案。
1、应用背景
A、汽车上各种电子控制单元的数目不断增加，连接导线显著增加，因浪涌损害的情况加剧。
B、总线的通信介质可以是双绞线、同轴电缆或光导纤维，通信速率可达1Mbps/40m，距离可达10km/40Kbps。
2、应用产品
A、车身电子控制系统（包括照明指示和车窗、刮雨器等）
B、废气再循环系统、巡航系统和空调系统
C、电控燃油喷射系统、电控传动系统
D、防抱死制动系统（ABS）
E、防滑控制系统（ASR）
3、应用方案
4、方案说明及注意事项
A、本方案采用残压很低的TSS，有效保护RS485/232芯片，满足IEC61000-4-5等浪涌标准。
B、方案中的TSS反应时间为ns级，既可防浪涌，又可防静电，满足IEC61000-4-2等静电标准。
C、方案中的TSS结电容小，信号无衰减，不影响控制线的传输。
D、本方案在差模、共模均采用的是同型号的TSS，防护无死角。
E、可通过10/700μS（等效内阻40ohm）浪涌测试，静电测试。

【经验】自恢复保险丝和TVS的结合使用，可防止四种情况造成的损坏
单独使用自恢复保险丝，或者与TVS二极管结合起来使用，都能防止负载电流过大、转换器出现故障、发动机激活时产生的瞬变电压以及汽车电池极性接反导致器件损坏。在选择PPTC自恢复保险丝器件时，必须考虑到最大负载电流、最高环境温度以及进入高阻抗状态所需要的时间。
