In a zener diode with high breakdown voltage
WebThe key difference between a Zener diode and a normal diode is that the Zener diode has a low breakdown voltage - typically in the few volts range. The breakdown voltage is low because the heavy doping means the depletion layer is very thin, and even at a low voltage the field strength over this thin depletion layer is very high. WebTwo tolerance series: ±2 % and approximately ±5 %. Wide working voltage range: nominal 2.4 V to 75 V (E24 range) Small plastic package suitable for surface-mounted design. Low differential resistance. Qualified according to AEC-Q101 and recommended for use in automotive applications.
