Features

The B340-13-F is a Schottky barrier diode with the following key features:
- Low forward voltage drop (~0.45V at 1A) for efficient power handling.
- High current capability (3A average forward current).
- Fast switching speed due to Schottky construction, reducing switching losses.
- Low reverse leakage current for improved efficiency.
- Surge current tolerance (up to 80A non-repetitive).
- Compact SOD-123FL package for space-saving PCB designs.
- Operating temperature range: -65°C to +125°C.
Ideal for power rectification, DC-DC converters, and reverse polarity protection in consumer electronics, automotive, and industrial applications.

Pinout

The B340-13-F is a Schottky barrier diode with 3 pins (anode, cathode, and common pin for dual-diode configuration).
Functions:
- Anode (A) & Cathode (K): Conducts current in forward bias with low voltage drop (~0.45V).
- Common Pin: Connects to both diodes in the package for shared cathode/anode setups.
- Applications: Rectification, reverse polarity protection, and high-efficiency switching.
Key Specs:
- Voltage: 40V (reverse).
- Current: 3A (forward).
- Package: SMB (surface-mount).
Concise and functional for circuit design.
