BZT52HC11WFQ-7

Single Zener Diodes Overview

The BZT52HC11WFQ-7 is a surface mount Zener diode manufactured by Diodes Incorporated, designed for automotive applications requiring specific change control. It is AEC-Q101 qualified and PPAP capable. The device utilizes an SOD123F package with a flat lead design for low profile and high power dissipation. Key electrical parameters include a nominal Zener voltage of 11V with a range of 10.4V to 11.6V at a test current of 5mA. Maximum Zener impedance is 70 Ohms at Izt and 70 Ohms at Izk. Power dissipation reaches 375mW on FR-4 PCB with minimum pad layout or 830mW with a 1cm² cathode pad. Operating temperature ranges from -65°C to +150°C.
