Overview
The onsemi BAR43S is a dual-series Schottky diode housed in a compact SOT-23-3 package, primarily designed for low-power rectification and signal switching applications. Its critical operational characteristic is the low forward voltage drop (Vf) of 800 mV at 200 mA, which minimizes power dissipation and voltage loss in sensitive circuits. A key design consideration when utilizing this device is managing its relatively low reverse voltage rating (Vrrm) of 30V; exceeding this can lead to premature breakdown and device failure, necessitating careful circuit design to prevent transient overvoltage conditions.
Key Features
- Dual Series Configuration
- 200 mA Forward Current (If)
- 30 V Repetitive Reverse Voltage (Vrrm)
- 800 mV Forward Voltage (Vf)
- 500 nA Reverse Current (Ir)
- SOT-23-3 Package (2.92 mm x 1.3 mm x 0.93 mm)
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- Low-voltage power supply rectification
- Reverse polarity protection in battery-powered devices
- Signal demodulation in RF receiver front-ends
- Voltage clamping for sensitive analog signal paths
