Product Specification

BAT54T1G SOT-23 Schottky Barrier Diode Dual Series 30V Reverse Voltage 200mA Current Low VF 0.32V High-Speed Switching 125°C Junction RoHS Compliant Tape & Reel Packaging

Features

• Extremely Fast Switching Speed

• Low Forward Voltage − 0.35 Volts (Typ) @ IF = 10 mAdc

• S Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q101 Qualified and PPAP Capable

• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant

Applications

1. High-Frequency Rectification & Signal Processing

RF Detection: Used in small-signal RF detection and mixing circuits due to its low voltage drop and fast switching characteristics.

High-Frequency Rectification: Acts as a freewheeling or rectifier diode in switch-mode power supplies (SMPS) and DC-DC converters to reduce switching losses.

2. Logic Circuits & Signal Clamping

Digital Circuit Protection: Protects I/O ports of digital chips (e.g., MCUs, FPGAs) from voltage spikes or reverse connection (clamping

protection).

Bidirectional Signal Blocking: Provides level isolation and reverse current protection in communication interfaces (e.g., I²C, SPI).

3. Power Management & Low-Power Devices

Low-Dropout Rectification: Ideal for battery-powered devices (e.g., portable electronics) due to its low voltage drop (0.32V), minimizing energy loss.

Power Path Management: Enables automatic switching and isolation between multiple power sources in mobile devices.

4. High-Speed Switching Circuits

Pulse and Digital Switching: Used for high-speed data line switching and modulation with nanosecond-level response time.

Sample-and-Hold Circuits: Provides fast turn-on/off in ADCs or analog switches.

5. General-Purpose Diode Replacement

Upgrade for Traditional Diodes: Replaces standard PN-junction diodes (e.g., 1N4148) to reduce power consumption and improve switching speed.

Description

These Schottky barrier diodes are designed for high speed switching applications, circuit protection, and voltage clamping. Extremely low forward voltage reduces conduction loss. Miniature surface mount package is excellent for hand held and portable applications where space is limited.
