BAT54

BAT54 Description

The BAT54 from NXP Semiconductors is a Schottky diode designed for high-efficiency, low-power applications. Packaged in a 3-pin SOT-23 surface-mount form factor, it offers a compact footprint (max dimensions: 3mm length × 1.4mm width × 1mm height) ideal for space-constrained designs. With a maximum DC reverse voltage of 30V and a continuous forward current of 0.2A, it balances performance and power handling. The diode features a low peak forward voltage of 0.8V at 0.1A, minimizing power loss, and a fast reverse recovery time of 5ns, enhancing switching efficiency.

BAT54 Features

• Low Power Dissipation: Max 250mW power dissipation ensures reliability in energy-sensitive circuits.
• Fast Switching: 5ns recovery time and 10pF max capacitance optimize high-frequency performance.
• Robust Protection: Withstands 0.6A surge current and operates up to 150°C, suitable for harsh environments.
• Compliance: EU RoHS compliant and EAR99 (ECCN), facilitating global deployment.
• Low Leakage: 2µA max reverse current at 25V reduces standby power consumption.
