Overview

The onsemi BAT54 is a high-performance silicon Schottky diode designed for efficient rectification and signal switching in low-power applications. Its critical operational characteristic is the exceptionally low forward voltage drop (Vf) of 800 mV at 200 mA, enabling reduced power dissipation and improved system efficiency. A key design consideration when implementing the BAT54 is managing its relatively low repetitive reverse voltage rating (Vrrm) of 30V; exceeding this threshold can lead to increased leakage current (Ir) and potential device failure, necessitating careful circuit design to prevent overvoltage transients.

Key Features

Forward Current (If): 200 mA
Repetitive Reverse Voltage (Vrrm): 30 V
Forward Voltage (Vf): 800 mV (at If = 200 mA)
Forward Surge Current (Ifsm): 600 mA
Reverse Current (Ir): 2 µA (at Vr = 25 V)
Package: SOT-23-3 (SMD/SMT)

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
High-frequency signal demodulation in RF circuits
Voltage clamping for sensitive digital interfaces
