Product Description

onsemi RB751S40T1G Schottky Diode is a surface mount discrete semiconductor device engineered for high-frequency, low voltage rectification applications. Housed in a compact SOD-523 package, this diode integrates the Schottky barrier principle using barrier metal to deliver optimal forward voltage drop and reduced reverse current, ideal for enhanced power efficiency and thermal performance.

This diode supports a maximum continuous forward current of 30 mA and can withstand a peak reverse repetitive voltage of 40 V, making it suitable for freewheeling, polarity protection, and switching power supply circuits. Its low forward voltage drop of 370 mV minimizes conduction losses.

The device complies with automotive-grade AEC-Q101 standards, qualifying it for automotive and industrial environments. Its wide operating temperature range from -55°C to 150°C ensures stable operation across varying ambient conditions. The epoxy moulded case safeguards against mechanical stress while maintaining a lightweight profile of about 11.7 mg.

The SOD-523 package dimensions are 1.3 mm length, 0.9 mm width, and 0.7 mm height, allowing for efficient PCB space utilization. With a peak reverse current limited to 500 nA, leakage is minimized, enhancing overall circuit reliability.

Maximum continuous forward current: 30 mA. Peak reverse repetitive voltage: 40 V. Low forward voltage drop: 370 mV. Automotive compliant to AEC-Q101 standard. Suitable for high-frequency rectification and polarity protection.

Epoxy moulded, lightweight SOD-523 package. Extended operating temperature range from -55°C to 150°C. Compact dimensions fit modern circuit board layouts. Low peak reverse current for minimal leakage.

This onsemi Schottky diode is ideal for industrial electronics, automotive systems, consumer electronics, and telecommunications applications requiring efficient, reliable low voltage rectification in compact form factors.
