Low-power voltage regulator diodes in a small SOD323 (SC-76) Surface-Mounted Device (SMD) plastic package.
The diodes are available in the normalized E24 ±1 % (BZX384-A), ±2 % (BZX384-B) and approximately ±5 % (BZX384-C) tolerance range. The series includes 37 breakdown voltages with nominal working voltages from 2.4 V to 75 V.
Total power dissipation: ≤300 mW
Three tolerance series: ±1 %, ±2 % and approximately ±5 %
Working voltage range: nominal 2.4 V to 75 V (E24 range)
Non-repetitive peak reverse power dissipation: ≤ 40 W

Description The NX-HB-GAN3R2-BSC half-bridge evaluation board provides the elements of a simple buck or boost converter. This enables the basic study of the switching characteristics and efficiency achievable with Nexperia’s 100V E-Mode GaN FETs. The circuit is configured for synchronous rectification, in either buck or boost mode. Selection jumpers allow the use of a single logic input or separate high / low level inputs. The voltage input and output can operate at up to 60 VDC, with a power output > 350 W

As a Nexperia customer you can order samples via our sales organization.
If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples. Check out the list of official distributors.
The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
