RB751V40T1G Description

Short technical summary and product information.

The RB751V40T1G is a Schottky barrier diode from On Semiconductor, optimized for high-speed switching applications, circuit protection, and voltage clamping. It offers an extremely low forward voltage of 0.28 V typical at 1 mA, reducing conduction loss in low-voltage designs. The diode is rated for a maximum reverse voltage of 30 V DC and a forward continuous current of 30 mA, with a peak forward surge current capability of 500 mA.

 

This device is housed in a miniature surface-mount SOD-323 package, making it ideal for space-constrained handheld and portable electronics. It features extremely fast switching speed and low reverse leakage current (300 nA typical at 30 V). The RB751V40T1G is Pb-Free, Halogen Free/BFR Free, and RoHS compliant, meeting environmental standards. It also carries ESD ratings of Class 1C (HBM) and Class A (MM) for robust handling.

 

Thermal characteristics include a maximum power dissipation of 200 mW on an FR-5 board at 25°C, with a derating factor of 1.57 mW/°C above 25°C. The junction-to-ambient thermal resistance is 635 °C/W. Operating temperature range is -55°C to +150°C. The device is supplied in tape and reel packaging with 3000 units per reel.
