Detailed Description

Ultra-small SOD-323 Schottky barrier diode in TE-17 tape-and-reel. RB751VM-40 denotes a 40 V reverse-voltage class device, widely known within the ROHM Group RB751 family. Compact, low-loss, and fast-switching for space-constrained designs and specialized modules. Main Category: Integrated Circuits (ICs). Small Classification: Specialized ICs. Package/Case code: 645. In-stock quantity at Y-IC: 5569 (subject to change).

Key Features

Schottky barrier technology for low forward voltage and fast switching

Reverse voltage class up to 40 V

SOD-323 footprint, 2-lead, surface-mount

TE-17 tape-and-reel packaging for automated SMT lines

Low capacitance and low leakage for clean signal paths

RoHS compliant, lead-free terminals

Stable performance in high-speed, low-current applications

Key Advantages

Lower power loss due to reduced forward drop

Faster transitions for improved efficiency in switching and rectification

Tiny footprint saves PCB area and enables placement close to IC pins

Simple protection/OR-ing/rectification with minimal parts count

Broad SMT process compatibility (pick-and-place, Pb-free reflow)

Cost-effective solution for portable and IoT designs

Packaging

Type: SOD-323 (JEDEC SOD-323, vendor case code 645)

Material: Molded epoxy/plastic package; tin-plated, lead-free terminations

Size: Approx. 2.6 mm x 1.3 mm x 1.1 mm (typical SOD-323 outline)

Pin configuration: 2 pins (Anode, Cathode). Polarity indicated by cathode marking band

Mounting: Surface-mount; TE-17 tape-and-reel for high-speed assembly

Thermal characteristics: Small thermal mass; ensure adequate copper area for heat spreading; apply derating at elevated ambient temperatures

Electrical properties: Schottky diode behavior (low VF, low capacitance, low leakage); reverse voltage class 40 V. Refer to the datasheet for exact maximum ratings, curves, and test conditions

Lifecycle

Expected active within ROHM Group/LAPIS Technology portfolios; not publicly flagged as near discontinuation at the time of writing. For second-source or alternatives, consider similar SOD-323 Schottky diodes in the 40 V class. Examples to evaluate: ROHM RB751 series variants; Nexperia BAS40 series; onsemi MMSD301 family; Diodes Inc. SD103 series. Always confirm electrical and mechanical equivalence (VF vs IF, IR, capacitance, surge current, footprint) against the original datasheet. If you need formally approved equivalents or the latest EOL/PCN status, please contact our sales team via the Y-IC website for detailed guidance.
