Infineon BAS3010B03WE6327HTSA1 Schottky Barrier Diode: Datasheet, Specifications, and Application Notes

The Infineon BAS3010B03WE6327HTSA1 is a high-performance Schottky Barrier Diode (SBD) designed for a wide range of modern electronic applications. As surface-mount technology (SMT) components become increasingly dominant, this diode offers an optimal blend of efficiency, speed, and miniaturization, making it a preferred choice for designers.

Key Specifications and Datasheet Overview

A thorough review of the datasheet reveals the component's core electrical characteristics, which are critical for circuit design:

Maximum Repetitive Reverse Voltage (VRRM): 30 V

Average Forward Rectified Current (IO): 0.5 A

Forward Voltage (VF): Typically 380 mV at IF = 0.1 A, a low value that minimizes power loss and improves efficiency.

Reverse Leakage Current (IR): 50 µA at VR = 30 V (typical at 25°C).

Operating Junction Temperature (Tj): -65 °C to +125 °C.

Package: The device is housed in an industry-standard SOD-323 (SC-76) plastic package, which is extremely compact and suitable for high-density PCB designs.

Advantages of the Schottky Barrier Design

This diode leverages the metal-semiconductor junction principle of Schottky diodes, which provides two significant advantages over conventional PN-junction diodes:

1. Very Fast Switching Speed: The absence of minority charge carriers eliminates reverse recovery time (trr), enabling operation in high-frequency circuits without significant switching losses.

2. Low Forward Voltage Drop: The lower VF leads to higher system efficiency, as less energy is dissipated as heat across the diode.

Primary Application Notes

The BAS3010B03WE6327HTSA1 is exceptionally versatile. Its primary applications include:

High-Frequency Rectification: Ideal for switching power supplies (SMPS), DC-DC converters, and AC-DC adapters where efficiency and speed are paramount.

Polarity Protection: Used as a reverse polarity protection diode in battery-powered devices and DC input circuits to prevent damage from incorrect power supply connection.

Signal Demodulation: Its fast switching characteristics make it suitable for RF and mixer circuits.

Clamping and Freewheeling Diodes: Used to suppress voltage spikes across inductive loads, such as relays and motors.

When integrating this diode, designers should consider:

Thermal Management: While the low VF reduces heating, ensuring adequate PCB copper area or a small heatsink is necessary when operating near its current limit at elevated temperatures.

Voltage Derating: For improved reliability, especially in harsh environments, operating the diode significantly below its 30 V maximum rating is recommended.
