【选型】音频模块电路中适用的Central高增益低噪声小信号晶体管选型
Central Semi(美国中央半导体公司)是世界顶级分立半导体制作商,公司总部位于美国纽约。公司生产的元器件产品具有高品质高可靠性;其与顶级OEM设计师合作,可为客户提供创新解决方案。其产品线包括:二极管、晶体管、整流器、场效应管、保护器件、多分立元器件等。
在平板电脑模块系统中,音频模块作为重要组成部分,分为扬声器模块,麦克风模块,耳机模块等。在各个模块的电路系统中,高增益、低噪声特性的小信号晶体管是系统高效工作的保障,Central Semi公司作为优秀的半导体制造商,推出了非常适用于音频模块电路的小信号晶体管器件,用于实现信号的放大增益功能。现对Central Semi此类小信号三极管的选型做如下说明。
CMUT5087E(PNP型)、CMUT5088E(NPN型)晶体管:
Central Semi生产的CMUT5087E和CMUT5088E是采用ULTRAmini™表面贴装封装的互补硅晶体管,具有增强的规格,专为需要高增益和低噪声的应用而设计。
两款小信号晶体管在室温(25℃)工作条件下,其集电极-基极电压为50V,最大集电极-发射极电压50V,最大发射极-基极电压为5.0V,集电极连续电流为100mA;其最大功率损耗为350mW。两者器件的最大工作和存储结温范围为-65℃~150℃,够很好保证平板电脑在极端环境下的正常工作;器件的热阻抗为357 ℃/W。两晶体管器件具体的电气参数如下:

图2 CMUT5087E、CMUT5088E晶体管实物图
CMPT3904E(NPN型)、CMPT3906E(PNP型)晶体管:
CMPT3904E和CMPT3906E是一对互补的硅晶体管,分别是CMPT3904和CMPT3906的增强型产品,专为小信号交换、接口电路和驱动程序电路应用而设计。其最主要的区别是封装形式不同,CMPT3904E和CMPT3906E采用SOT-23封装,封装尺寸为2.80mm*1.19mm*0.89mm。而上文所述的CMUT5087E和CMUT5088E采用SOT-523封装,封装尺寸为1.50mm*0.78mm*0.58mm。CMPT3904E和CMPT3906E的封装尺寸更小,对于更为紧凑的PCB设计,是非常理想的选择。
在电气参数方面。两者在室温(25℃)工作条件下,其最大集电极-基极电压为60V,最大集电极-发射极电压40V;最大发射极-基极电压为6.0V, 集电极连续电流为200mA;其最大功率损耗为350mW。两者器件的最大工作和存储结温范围为-65℃~150℃,能够很好满足设备在极端环境下的正常工作;器件的热阻抗为357 ℃/W。两晶体管器件具体的电气参数如下:
图3 CMPT3904E、CMPT3906E晶体管电气参数列表
图4 CMPT3904E、CMPT3906E晶体管实物图
CET3904E(NPN型)、CET3906E(PNP型)晶体管:
Central Semi生产的CET3904E和CET3906E互补硅晶体管,其采用Tiny Leadless Package TLP™封装(SOT-883L),封装尺寸为0.95mm*0.55mm*0.30mm,超小的封装适合尺寸要求最苛刻的约束应用。另外,该产品的集电极-射极饱和压降VCE(SAT)仅为0.1V,具有超低的饱和压降。因此,相较上两款产品,该产品设计适用于对尺寸和功耗有严格要求的应用场景。
在电气参数方面。两款小信号晶体管在室温(25℃)工作条件下,其最大集电极-基极电压为60V,最大集电极-发射极电压40V;最大发射极-基极电压为6.0V, 集电极连续电流为200mA;标准安装条件下其最大功率损耗仅为250mW。两者器件的最大工作和存储结温范围为-65℃~150℃,符合军品级器件的温度要求;标准安装条件下,器件的热阻抗为500 ℃/W。两晶体管器件具体的电气参数如下:
