血糖仪，可以实时检测及记录糖尿病人的血糖浓度，一般来说，血糖仪不会每时每刻都要检测及记录血糖浓度，可以根据病情记录某些时间段内的血糖浓度即可。因此，血糖仪内部都集成有定时器电路，以确保血糖仪能够在特定的时间点上检测及记录血糖浓度。由于血糖仪的检测结果与病人的生命安全息息相关，这也就要求其定时器电路必须选择性能优异的元器件。

图1 Central的血糖仪解决方案中的定时器模块

在定时器电路的器件选型上，Central推荐使用的电子元器件类型和型号分别为：高速开关二极管(CMLD4448/CMAD4448)；肖特基二极管(CTLSH01-30L/CMASH-4/CFSH01-30)和齐纳二极管(CMOZ3V3C thru CMOZ12VC)，这些元器件可以保证定时器有较好的开关速度，和瞬态电压防护能力，保证定时器稳定工作。具体的电气参数如表1~表3所示。

表1 高速开关二极管(CMLD4448/CMAD4448)的电气参数

表2 肖特基二极管(CTLSH01-30L/CMASH-4/CFSH01-30)的电气参数

表3 齐纳二极管(CMOZ3V3C~CMOZ12VC)的电气参数
