1PS76SB21,115 Schottky Barrier Diode (40V, 200mA, SOD-323)

Preserve every drop of precious voltage in your low-power circuits with the 1PS76SB21 Schottky barrier diode. When you need to protect a delicate 3.3V sensor from reverse polarity, or safely combine two power sources (like a USB port and a LiPo battery) using a "Diode OR" configuration, standard silicon diodes waste too much energy by dropping 0.7V. This highly efficient Schottky diode solves that problem by offering a significantly lower forward voltage drop, ensuring your logic chips and microcontrollers get the power they need to operate flawlessly.

Rated for up to 40V and 200mA of continuous forward current, it is the perfect small-signal companion for your DIY electronics. Its extremely fast switching speed also makes it an excellent choice for signal clipping, logic level clamping, and acting as a flyback (freewheeling) diode to protect GPIO pins from the inductive kickback of micro-relays. Housed in a microscopic SOD-323 surface-mount package, it is an essential, space-saving building block for IoT sensor nodes, Arduino shields, and custom drone peripherals.

Key Features:

• Ultra-Low Voltage Drop: Minimizes power loss and voltage starvation in 3.3V and 5V logic circuits compared to standard P-N junction diodes.

• Power OR-ing Champion: The ideal component for safely managing dual power inputs (e.g., USB and Battery) on custom microcontroller boards.

• High-Speed Switching: Extremely fast recovery time makes it perfect for high-frequency signal processing and protective clamping.

• Space-Saving SOD-323: The tiny SMD footprint requires virtually zero board space, perfect for highly miniaturized electronics.
