【选型】智能门锁项指纹识别ESD防护设计推荐双向TVS管TPA1006L,接触放电能力达10kV
为避免智能门锁指纹识别器因人体接触造成的ESD振击导致相关敏感的电子器件被打死,一般需要在指纹识别器和主控MCU通信的信号上做ESD防护,通常加一款小型化TVS管做ESD防护即可,典型应用电路示意图参考如下图1所示。
图1:智能门锁指纹识别ESD防护应用电路示意图
其中TVS管选型一般需要考虑如下几点因素:
1、高的抗ESD能力,至少满足IEC 61000-4-2 (ESD) ±15kV (Air)、±8kV (Contact);
2、小尺寸,满足智能门锁空间结构紧张的设计
3、低成本
针对如上设计考量,推荐选择电安科技的TVS管TPA1006L,是一款低电容瞬态抑制器,典型结电容低至0.6pF,采用DFN1006封装,最大反向工作电压5V,最小击穿电压6V,最大反向漏电流0.5μA,最大钳位电压20V@ IPP=4A,工作温度范围-55℃~125℃,相关电性参数如下图2所示。
图2:电安科技TVS管TPA1006L相关电性参数示意图
推荐电安科技TVS管TPA1006L理由如下:
1、低容值:0.6pF低的典型结电容,有助于维护信号完整性,并最大限度地减少数据丢失,同时提供免受电气威胁的更强大设备。
2、高抗ESD能力:满足IEC 61000-4-2 (ESD) ±15kV (Air)、±10kV (Contact),具有出色的抗ESD能力;
3、小尺寸:采用DFN1006封装,典型封装尺寸为1.0mm x 0.6mm,可满足小型化设计需求;
4、世强常备库存,具有更好的供货周期,可快速支持样品和后续量产服务;

【选型】商用车空调压缩机控制器24V电源输入过抛负载防护,推荐8000W双向TVS管SM8T36C
为保证商用车空调压缩机控制器24V电源输入,可通过新标准ISO16750-2 5a抛负载测试,要求10分钟做10次测试,每两次间隔1分钟,一般需要通过高功率TVS管并联在电源输入端做过压防护,推荐选择电安科技车规级8000W双向TVS管SM8T36C,最大反向工作电压36V,最大钳位电压58.1V,最大峰值脉冲电流137.7A,有通过车规级AEC-Q101认证。
【选型】ESD抑制器TPA1006L1用于I²C接口静电防护,结电容0.5pF,ESD等级±15kV
I²C总线接口广泛用于各类电子产品中,为提高产品可靠性和保护后端器件,通常会在I2C总线接口处增加ESD防护方案,本文推荐国产电安科技的ESD抑制器TPA1006L,工作电压5.0V,结电容0.5pF,反向漏电流0.1μA,峰值脉冲功率100W。
【选型】可pin to pin替代Bourns CG0402MLC-24LG的国产ESD保护器件,结电容0.3pF
