BZT52C51-7 Description

Short technical summary and product information.

The BZT52C51-7 is a planar Zener diode from Diodes Incorporated, designed for general purpose voltage regulation applications. It features a nominal zener voltage of 51V with a tolerance of ±6%. The device is capable of dissipating up to 500mW at a lead temperature of +75°C and 370mW at an ambient temperature of +25°C. The maximum forward voltage is 0.9V at 10mA, and reverse leakage current is limited to 100nA at 38V. The typical zener impedance is 100Ω. The device is housed in a compact SOD-123 surface mount package, weighing approximately 0.010 grams, with matte tin finish terminals and a cathode band polarity marking. It operates over a junction temperature range of -65°C to +150°C and is qualified to AEC-Q101 standards. This component is ideal for automated assembly processes and comes in tape and reel packaging (3000 pcs per reel) for commercial applications.
