Diodes Incorporated announces the introduction of their Zener diode series, housed in the compact SOD123F package. This high-performance, small footprint, flat-lead package is designed with lower thermal resistance (RΘJA=150°C/W) which enables higher power dissipation and better heat transfer properties, compared to the legacy BZT52C series in the traditional SOD123 package.

The BZT52HCxxWF series comprises 32 Zener diodes, with nominal Zener voltage ranging from 2.4 V to 47 V. These diodes are excellent for precise voltage reference functions, due to the sharp Zener breakdown characteristics and around ±5% voltage tolerance. In addition, with a low leakage current of 50 nA for some devices, energy efficiency is greatly improved. This series is an exact pin-for-pin, drop-in replacement to NXP’s BZT52H-C series.

These devices are ideally suited for general regulation purposes. The SOD123F package is fully green and RoHS-compliant.

Features

• Exceptional thermal transfer characteristics: The flat-lead design of the SOD123F package (3.5 mm x 1.8 mm typical) supports high power dissipation and improved stability.
• Good voltage tolerance and low leakage current: The voltage tolerance is ±5% from nominal, which means the voltage variations are kept to a minimum. Furthermore, low leakage current, as low as 50 nA, ensures good energy efficiency is achieved.
• Wide selection of Zener voltages: The BZT52HCxxWF series has a large selection of Zener voltages, ranging from 2.4 V to 47 V, which covers most design specification requirements.
• Low Zener impedance: With a low Zener impedance rating, these diodes are more stable and accurate. The voltage stays constant irrespective of current or loading.
