The Diodes Incorporated BZT52C27Q-7-F is a 27V automotive surface-mount Zener diode designed for voltage regulation, reference, clamping, and general overvoltage-protection applications. The Q version is automotive qualified to AEC-Q101 and uses a compact SOD123 package.
The device has a nominal 27V Zener voltage. At IZT = 2mA, the specified Zener-voltage range is 25.1V to 28.9V. Maximum Zener impedance is 80Ω at 2mA, while maximum low-current impedance is 300Ω at IZK = 0.5mA.
Maximum reverse leakage current is 0.1µA at 18.9V, and maximum forward voltage is 0.9V at 10mA. These characteristics make the device suitable for automotive control units, sensor interfaces, supply monitoring, and general-purpose voltage protection.
Diodes Incorporated rates the device as a 500mW Zener diode. The datasheet specifies 500mW at TL = 75°C, while power dissipation is 370mW at TA = 25°C on the specified FR-4 PCB layout, so thermal derating should be considered in real designs.
The exact BZT52C27Q-7-F orderable part is supplied in SOD123 on 3,000-piece tape-and-reel packaging. It is MSL Level 1, operates from -65°C to +150°C, and is lead-free, RoHS compliant, halogen-free, and antimony-free.
