稳压二极管(Zener diode)已经非常广泛的应用在各种电子设备中,比如开关电源,工业机器人,个人电脑,投影仪,汽车电子等等。既然这么多产品都会用到稳压二极管,那怎么能快速准确地选择出自己需要的那一款呢?笔者此前负责的多个项目中,为了MOSFET的稳压驱动,采用Central Semi 的稳压二极管,积累了一定的选型和应用经验,借此分享给大家,希望对在一般选型应用中提供一些帮助。

笔者在隔离开关电源设计项目中,需要选用一款稳压二极管用于对MOSFET的门级驱动电压进行稳压保护。结合项目,选用稳压二极管的基本条件为:额定稳定电压达到12V,额定输出功率大于200mW,封装尺寸要小,为贴片封装,而且精度高,温度系数好,工作温度范围广。


结合隔离开关电源设计项目需求,按照以下步骤进行稳压二极管的选型设计:

1、确定稳压二极管在电路中的位置和作用;

2、选择合适的稳压二极管参数;

3、确认供货周期和价格。


1)确定稳压二极管在电路中的位置和作用

根据笔者设计的一个隔离开关电源设计项目,需要对电源输出的电压时序进行约束,采用MOSFET作为开关器件,并选用稳压二极管对MOSFET的门级驱动电压进行稳压保护。开关电源时序控制电路的工作原理图如图1所示。

图1时序控制电路工作原理图



在电路中,VIN输入电压通过电阻分压进行MOSFET的开关驱动,稳压二极管D4在MOSFET管Q3的G基电压处,作用是保证MOSFET的驱动电压在安全工作范围内。

通过手册可以得知MOSFET的驱动电压在5-20V之间,如果驱动电压超过20V就会损坏,因此采用稳压二极管限制电压对MOSFET进行保护。


2)选择合适的稳压二极管参数

已经得知稳压二极管的位置和作用是保护MOSFET不超过安全工作电压,对其进行保护。接下来就是怎么选择稳压二极管的参数。


图2稳压二极管工作示意图


根据手册得知,稳压二极管的关键参数主要有以下几点:

1)稳定电压

稳定电压指稳压管通过额定电流时两端产生的稳定电压值。MOSFET的G基一般要求小于20V,正常情况下的驱动电压选用12V。在隔离开关电源设计项目中,选用Central Semi 公司的1个BZX84C12TR作为MOSFET的G基的稳压保护,稳定电压为12V,可实现MOSFET的稳态正常运行,保护MOSFET的驱动电压不会超过额定范围,满足项目需求。

2)额定功耗

稳压二极管的额定功耗为稳定电压和允许最大电流的乘积,也由芯片允许温升决定。MOSFET的驱动电流很小,满足200mW就可工作,稳压二极管BZX84C12TR的功耗可达到350mW,可完全满足在开关电源设计项目中电路的稳压使用,并可以抗击浪涌功率损耗。

3)温度系数

如果稳压管的温度变化,它的稳定电压也会发生微小变化,温度变化1℃所引起管子两端电压的相对变化量即是温度系数。温度系数好的稳压二极管稳定电压会更稳定。BZX84C12TR的温度系数只有0.05%/℃,温度系数很稳定,在电路中稳定电压也很精准,满足项目的高精度要求。

4)温度范围、封装形式与尺寸

笔者设计开关电源设计项目,最高的环境温度为85℃,稳压二极管BZX84C12TR的工作温度范围-65℃到150℃,可见其工作温度范围很宽,从而能够降低由于系统发热带来的故障风险,效率更高。

其封装形式为标准的SOT-23贴片封装,这个封装为标准封装,在画PCB时可以直接借用此封装,占用PCB空间小,不用自己动手画封装,带来很大方便,在项目设计时也节省很多时间。

3)确认供货周期和价格

最后跟厂家沟通,Central Semi 公司的产品在能源,照明,工业,消费,网络,医疗等市场广泛应用;而且供货周期短,价格合适。最终选用Central Semi 公司的稳压二极管BZX84C12TR作为电路的保护器件。

在开关电源设计项目中,采用MOSFET管和光耦进行时序电路设计,选用稳压二极管作为MOSFET的驱动稳压保护,为系统的稳定运行带来保护作用。
