BZX84C51-7 Description

Short technical summary and product information.

The BZX84C51-7 is a 51V Zener diode from Diodes Incorporated, designed for voltage regulation and clamping in low-power circuits. It offers a nominal Zener voltage of 51V with a tolerance of ±6% (48V minimum, 54V maximum) at a test current of 2mA. The device features a maximum Zener impedance of 180Ω at IZT and 400Ω at IZK (0.5mA).

This Zener diode has a power dissipation rating of 300mW when mounted on an FR-4 PC board with recommended pad layout, or 350mW when the terminals are kept at ambient temperature. The forward voltage is 900mV at 10mA, and reverse leakage current is 100nA at 35.7V. The operating and storage temperature range spans -65°C to 150°C.

The BZX84C51-7 is housed in a surface-mount SOT-23-3 package, weighing approximately 0.008 grams. It features molded plastic case material rated UL 94V-0, matte tin terminal finish annealed over Alloy 42 leadframe, and is lead-free, halogen-free, and RoHS compliant. Moisture sensitivity level is 1 per J-STD-020D. This device is ideally suited for automated assembly processes.
