BAT54

BAT54 Description

The BAT54 is a Schottky barrier diode from Rectron USA, designed for high-efficiency switching applications. This surface-mount (SMD/SMT) device features a single-diode configuration in a compact 3-pin SOT-23 package, supplied in tape and reel (T/R) for automated assembly. With a maximum DC reverse voltage of 40V and a forward current rating of 200mA, it offers low forward voltage drop (1V @ 0.1A) and ultra-fast 5ns reverse recovery time, minimizing switching losses. Its silicon (Si) technology ensures reliable performance in high-speed circuits.

BAT54 Features

• Low Power Dissipation: 200mW maximum power dissipation for energy-efficient operation.
• High Surge Current Handling: 600mA peak non-repetitive surge current (Ifsm) for transient protection.
• Low Leakage Current: 2µA reverse current (Ir) at 25V enhances efficiency.
• Wide Temperature Range: Operates from -55°C to +150°C, suitable for harsh environments.
• RoHS & EU RoHS Compliant: Meets environmental and safety standards.
• Compact SOT-23 Package: 3mm x 1.4mm x 1.05mm dimensions save PCB space.

BAT54 Applications

• High-Speed Switching: Ideal for DC-DC converters, voltage clamping, and reverse polarity protection due to fast recovery.
• Signal Demodulation: Used in RF and mixer circuits for low-loss rectification.
• Portable Electronics: Fits battery-powered devices (e.g., smartphones, wearables) thanks to low Vf and minimal leakage.
• Automotive & Industrial: Despite non-automotive grading, it suits low-voltage industrial controls and sensor interfaces.

Conclusion of BAT54

The BAT54 stands out for its fast switching, low forward voltage, and compact form factor, making it a versatile choice for high-frequency and power-sensitive designs. Its balance of performance and cost is ideal for consumer electronics, power management, and signal processing. Engineers favor it for space-constrained applications where efficiency and reliability are critical.
