MMSZ52 Surface Mount Zener Diodes

Taiwan Semiconductor MMSZ52 Surface Mount Zener Diodes are AEC-Q101 qualified diodes that are ideally suited for automated assembly processes. These diodes feature a 2.4V to 75V Zener voltage selection range with ±5% tolerance and exhibit 500mW power dissipation. The MMSZ52 diodes offer a -55°C to 150°C storage temperature range and come in an SOD-123 package. These MMSZ52 surface mount Zener diodes are used in applications that require general regulation functions.
