onsemi 50 V 500 mA Schottky Diode Surface Mount 3-Pin SOT-23 SB05-05C-TB-E

onsemi SB05-05C-TB-E is a high-performance Schottky diode designed for low voltage, high frequency rectification and protection in electronic circuits. This diode employs the Schottky barrier principle with a barrier metal to achieve an optimum balance of forward voltage drop and low reverse leakage current, making it suitable for efficient power management in compact electronic assemblies.

Its surface mount SOT-23 package with three pins allows for automated placement on printed circuit boards (PCBs), enabling efficient high-volume manufacturing. The device's small footprint with dimensions of 2.9 mm length, 2.5 mm width, and 1.15 mm height helps conserve PCB space without compromising performance. The robust epoxy moulded case ensures durability and environmental protection.

This Schottky diode supports a maximum continuous forward current of 500 mA and a peak reverse repetitive voltage rating of 50 V. The low forward voltage of 550 mV reduces power loss during conduction, while the diode exhibits a peak reverse current of just 50 μA to maintain efficiency in sensitive circuits. The device can withstand peak non-repetitive forward surge currents up to 5 A, providing transient tolerance.

Operating temperature range from -55°C to 125°C suits industrial and commercial electronic applications where thermal stability is essential. Its rapid peak reverse recovery time of 10 ns enables switching efficiency in high frequency and switching power supply applications.

Common use cases for the SB05-05C-TB-E diode include use as freewheeling diodes in DC-DC converters, polarity protection diodes in portable and battery-powered devices, and rectifier diodes in power supplies for computers, communication equipment, and automotive electronics.

The device is Pb-free and optimized for automated board assembly, meeting modern environmental and manufacturing standards. It features stress protection guarding for enhanced reliability under mechanical and thermal stress.

The diode utilizes Schottky barrier technology for low forward voltage drop and fast switching. It features a single diode configuration with a compact 3-pin SOT-23 package. Operating temperature range spans from -55°C to 125°C ensuring high reliability.

Peak non-repetitive forward surge current capability of 5 A enhances transient handling. Small physical dimensions (2.9 mm length, 2.5 mm width, 1.15 mm height) optimize PCB space. Maximum forward voltage is 550 mV, ideal for low power rectification.

The peak reverse current is only 50 μA, minimizing leakage in sensitive circuits. Epoxy moulded case construction provides mechanical strength and moisture resistance. Suitable for automated assembly due to its surface mount configuration and lightweight design.

Widely applicable in power supplies, polarity protection, freewheeling diodes, and high-frequency switching devices. Explore more electronic components and semiconductor devices in the Schottky Diodes & Rectifiers category at EnvMart to enhance your designs and manufacturing processes.
