Detailed Description

Ultra‑miniature Schottky rectifier diode in SOD‑723F for space‑critical designs. 30 V reverse voltage rating, 100 mA average rectified current, low forward drop for better efficiency, very low leakage for low‑power systems, and fast switching for small‑signal use. RoHS3 compliant. Supplied in tape and reel for automated assembly.

Key Features

Schottky technology for very fast switching and low forward loss

Vf 450 mV max at 10 mA for improved efficiency

Reverse leakage 500 nA max at 10 V for low standby drain

30 V DC reverse voltage rating

100 mA average rectified current (Io) for small‑signal rectification

Tiny SOD‑723F footprint for high‑density layouts

Surface‑mount for standard SMT reflow

RoHS3 compliant

Key Advantages

Saves board space with an ultra‑small package

Reduces power loss and heat thanks to low Vf

Extends battery life with very low leakage

Enables high‑speed signal rectification with near‑zero reverse recovery

Simplifies automated manufacturing with tape‑and‑reel packaging

Trusted Taiwan Semiconductor quality backed by Y‑IC distribution

Packaging

Type: SOD‑723F, 2‑lead, plastic‑molded, surface‑mount diode

Material: Molded epoxy body, copper leadframe, matte tin terminal finish

Approximate size: about 1.2 mm x 0.8 mm x 0.5 mm overall footprint (ultra‑miniature)

Pin configuration: 2 terminals (Anode and Cathode). Cathode is typically marked by a polarity line or dot on the body. Verify PCB orientation with datasheet marking.

Tape & Reel: Industry‑standard embossed carrier tape for SMD; optimized for high‑speed pick‑and‑place. Typical 8 mm tape width; reel quantities vary by supplier lot. Contact us if you need exact reel count.

Thermal characteristics: Operates up to 125°C junction temperature. Power dissipation depends on PCB copper area and airflow; limited heatsinking in SOD‑723F. Follow derating in datasheet to keep within safe limits.

Electrical properties summary:

- Technology: Schottky

- Vf max: 450 mV at 10 mA

- Reverse leakage: 500 nA at 10 V

- Average rectified current: 100 mA

- DC reverse voltage: 30 V max

- Speed: Small‑signal, very fast switching

Lifecycle

Status: Generally active and widely used in production for miniature designs

Discontinuation risk: Not indicated as nearing discontinuation based on typical market availability

Equivalent or alternative models:

- Same manufacturer, similar spec in micro SMD packages: Taiwan Semiconductor RB520 series variants (check exact package and ratings)

- ROHM RB520S‑30 family (commonly SOD‑523; verify footprint and polarity)

- Diodes Incorporated and Nexperia offer comparable 30 V small‑signal Schottky diodes in micro SMD packages; verify current rating and package size

- Important: Always confirm package (SOD‑723F vs SOD‑523/SOD‑323), pin orientation, and electrical limits before substituting
