下文介绍了BRT的关键电气特性。
在数据表中,除非另有说明,否则均按25°C的环境温度(Ta)指定数据表中的电气特性。除了电气特性表中显示的数值外,还请务必参考各个图表。
1.输入电压(导通),VI(ON)
VI(ON)是指晶体管在额定工况下让额定电流通过所需的输入电压。为顺利导通BR,必须在基极(B)和发射极(E)端子上施加高于最大输入电压(导通)(VI(ON))的电压。
IC–VI(ON)曲线表明VI(ON)随着温度升高而降低。
特性 | 符号 | 测试电路 | 测试条件 | 最小值 | 典型值 | 最大值 | 单位 | ||
---|---|---|---|---|---|---|---|---|---|
输入电压(导通) | RN1401 | VI(ON) | — | VCE=0.2V,IC=5mA | 1.1 | — | 2.0 | V | |
RN1402 | 1.2 | — | 2.4 | ||||||
RN1403 | 1.3 | — | 3.0 | ||||||
RN1404 | 1.5 | — | 5.0 | ||||||
RN1405 | 0.6 | — | 1.1 | ||||||
RN1406 | 0.7 | — | 1.3 |
2.输入电压(关断),VI(OFF)
VI(OFF)是指满足将BRT定义为关断的条件所需的输入电压。为顺利地关断BRT的关断,必须在基极(B)和发射极(E)端子上施加低于最小输入电压(关断)(VI(OFF))的电压。与VI(ON)一样,VI(OFF)随温度升高而降低。
特性 | 符号 | 测试电路 | 测试条件 | 最小值 | 典型值 | 最大值 | 单位 | ||
---|---|---|---|---|---|---|---|---|---|
输入电压(关断) | RN1401至1404 | VI(OFF) | — | VCE=5V,IC=0.1mA | 1.0 | — | 1.5 | V | |
RN1405,1406 | 0.5 | — | 0.8 |
3.集电极-发射极饱和电压,VCE(sat)
VCE(sat)是指BRT在额定电流下在饱和区内工作时的集电极-发射极电压。VCE(sat)–IC曲线表明,VCE(sat)随着温度升高而增大。
特性 | 符号 | 测试电路 | 测试条件 | 最小值 | 典型值 | 最大值 | 单位 | ||
---|---|---|---|---|---|---|---|---|---|
集电极-发射极 饱和电压 |
RN1401至1406 | VCE(SAT) | — | IC=5mA,IB=0.25mA | — | 0.1 | 0.3 | V |
4.输入电阻,R1
R1是与BRT的基极端子串联的电阻的值。对于以下所示的BRT,R1的变化为±30%。R1会影响VI(ON)和其它特性。R1以大约0.2%/℃的速率降低。
特性 | 符号 | 测试电路 | 测试条件 | 最小值 | 典型值 | 最大值 | 单位 | ||

RN1403 | 15.4 | 22 | 28.6 | ||||||
RN1404 | 32.9 | 47 | 61.1 | ||||||
RN1405 | 1.54 | 2.2 | 2.86 | ||||||
RN1406 | 3.29 | 4.7 | 6.11 |
5.电阻比,R1/R2
电阻比(R1/R2)是指R1电阻与R2电阻之比。对于以下所示的BRT,R1/R2的变化为±10%。未单独指定基极-发射极电阻(R2)的值,但指定了电阻比(R1/R2),因为它更重要。
特性 | 符号 | 测试电路 | 测试条件 | 最小值 | 典型值 | 最大值 | 单位 | ||
---|---|---|---|---|---|---|---|---|---|
阻值比 | RN1401至1404 | R1/R2 | — | — | 0.9 | 1.0 | 1.1 | — | |
