Product Overview

B540C-13-F is a high-performance 5A surface-mount Schottky barrier rectifier diode with SMC package, featuring core parameters of 40V repetitive peak reverse voltage and 5A average rectified output current. It has a maximum forward voltage drop of only 0.55V at 5A operating current and can withstand 100A non-repetitive peak forward surge current. Certified to JEDEC high-reliability standards and compliant with RoHS and halogen-free environmental requirements, this product incorporates a guard ring chip structure for transient protection. It is an excellent choice for medium-to-high power scenarios such as low-voltage high-frequency inverters, freewheeling protection, and polarity protection, and is widely used in industrial power supplies and consumer electronics fast chargers.

• High-reliability design: Adopts guard ring chip structure for transient voltage protection and complies with JEDEC high-reliability standards
• Eco-friendly and production-line compatible: Lead-free plating meets the full range of RoHS directives, and SMC package is compatible with automated SMT production lines to improve production efficiency

Technical Specifications

Typical Applications

• 1. Fast Charging Power Supplies for Consumer Electronics : In the rectifier circuits of high-power desktop fast chargers and energy storage power banks, the 5A high-current capability of B540C-13-F can meet the high-power transmission needs of fast charging. The 0.55V low forward voltage drop can reduce heat generation and power consumption during power conversion, helping fast charging devices achieve high conversion efficiency and miniaturized design. Meanwhile, the SMC package is suitable for the compact PCB layout inside the device.
• 2. Industrial High-Frequency Inverters : For the rectifier circuits of industrial low-voltage high-frequency inverters, the Schottky characteristics of this device can adapt to high-frequency switching conditions, avoiding efficiency attenuation at high frequencies. The wide temperature range of -55℃~+150℃ can cope with temperature fluctuations in industrial environments, and the guard ring structure can also resist circuit transient interference, ensuring the long-term stable operation of the inverter.
• 3. Motor Drive Freewheeling Circuits : In the drive freewheeling protection circuits of small industrial motors and smart home motors, B540C-13-F can quickly discharge inductive energy storage. The 100A surge withstand capability can resist instantaneous large current shocks during motor start and stop, preventing damage to the drive circuit due to overcurrent and improving the safety and reliability of the motor system.
• 4. Power Interface Polarity Protection : In the power interface polarity protection scenarios of various high-power electronic devices, the low forward voltage drop of this diode can reduce energy loss during normal power supply, and the 40V reverse voltage resistance can effectively block the current of reverse power connection, avoiding device burnout due to incorrect power polarity and providing reliable polarity protection for the device.
• 5. DC-DC Converters : In industrial and automotive DC-DC conversion circuits (non-automotive grade auxiliary circuits), its high-current carrying capacity and low-power consumption characteristics can achieve efficient voltage conversion. The excellent thermal resistance parameters can ensure the heat dissipation performance of the device under high load, adapting to the continuous high-power working needs of the converter.

Why Choose B540C-13-F ?
