BAV99

BAV99 Description

The BAV99 from EIC Semiconductor, Inc. is a high-speed switching diode designed for precision applications requiring fast recovery and low power dissipation. This dual-series configuration diode features a maximum DC reverse voltage of 75V and a peak repetitive reverse voltage of 85V, making it suitable for moderate-voltage circuits. With a peak forward voltage of 1.25V at 0.15A and a maximum continuous forward current of 0.125A, it balances efficiency and performance. The ultra-fast reverse recovery time of 4ns ensures minimal switching losses, while the low peak reverse current (1µA) enhances reliability in sensitive applications. Packaged in a compact 3-pin SOT-23 with a footprint of 3.1mm x 1.65mm x 1.3mm, it is optimized for surface-mount PCB designs.
