CDBP0130R-G Schottky Diode 30V 100mA SOD-723 Equivalent & Substitute Parts

Part Overview

The CDBP0130R-G is a Schottky rectifier diode manufactured by Comchip Technology, rated for 30V DC reverse voltage and 100mA average rectified current in a surface mount SOD-723 package. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. Equivalent parts must maintain identical electrical performance characteristics and mechanical compatibility to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDBP0130R-G is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 100 mA
• Speed Classification: Small Signal ≤ 200mA (Io), Any Speed
• Mounting Type: Surface Mount
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variations:

• Voltage - Forward (Vf) (Max) @ If: Within component specification limits
• Current - Reverse Leakage @ Vr: Within component specification limits
• Package / Case: SOD-723 or equivalent mechanical footprint (SOD-523, EMD2)
• Operating Temperature - Junction (Max): Equal to or greater than 125°C
• Product Status: Active preferred for long-term availability

Three substitute parts meet these criteria and are grouped as follows:

Group 1 - Parametric Equivalent (Identical Package): RB520G-30 RLG by Taiwan Semiconductor Corporation maintains identical SOD-723 packaging and electrical characteristics.

Group 2 - Manufacturer Recommended Substitutes (Alternative Package): RB510SM-30T2R and RB511SM-30T2R by Rohm Semiconductor provide electrical equivalence with alternative EMD2 packaging (SC-79, SOD-523 mechanical compatibility).

Engineering Selection Recommendations

For Direct Package Replacement (SOD-723): RB520G-30 RLG by Taiwan Semiconductor Corporation is the preferred substitute when PCB layout and mechanical constraints require SOD-723 packaging. This part maintains identical electrical specifications and package geometry, enabling direct substitution without PCB redesign. The part is currently in active production status with ROHS3 compliance and 3654 units in stock inventory.

For Alternative Package Designs (EMD2/SOD-523): RB510SM-30T2R and RB511SM-30T2R by Rohm Semiconductor provide electrical equivalence with alternative surface mount packaging. These parts are suitable for new designs or redesigns where EMD2 (SC-79, SOD-523) packaging is acceptable. Both parts are in active production status with ROHS3 compliance.

RB510SM-30T2R offers superior reverse leakage performance (300 nA @ 10 V) and extended junction temperature rating (150°C maximum), providing enhanced thermal margin in high-temperature applications.

RB511SM-30T2R features reduced forward voltage drop (370 mV @ 10 mA) compared to the original part, resulting in lower power dissipation in rectification circuits.

All substitute parts maintain REACH Unaffected status and EAR99 export classification consistent with the original component.

Frequently Asked Questions (FAQ)

Q: Can RB520G-30 RLG be used as a direct replacement for CDBP0130R-G without PCB modification?

A: Yes. RB520G-30 RLG maintains identical SOD-723 package geometry and electrical specifications (30V, 100mA, 450mV forward voltage, 500nA reverse leakage). No PCB layout changes are required.

Q: What is the difference between RB510SM-30T2R and RB511SM-30T2R?

A: Both parts share identical voltage and current ratings (30V, 100mA). RB510SM-30T2R has lower reverse leakage (300 nA @ 10 V) and higher junction temperature rating (150°C). RB511SM-30T2R has lower forward voltage drop (370 mV @ 10 mA) and standard junction temperature (125°C). Selection depends on circuit requirements for leakage performance or power dissipation.

Q: Are the Rohm parts (RB510SM-30T2R, RB511SM-30T2R) mechanically compatible with SOD-723 PCB footprints?

A: No. Rohm parts use EMD2 packaging (SC-79, SOD-523 mechanical footprint), which differs from SOD-723. PCB redesign is required for these substitutes. Use RB520G-30 RLG for direct SOD-723 footprint compatibility.

Q: What is the inventory status of substitute parts?

A: RB520G-30 RLG: 3654 units in stock. RB510SM-30T2R: 56300 units in stock. RB511SM-30T2R: 16300 units in stock. All parts are in active production.

Q: Do all substitute parts meet RoHS compliance?

A: Yes. RB520G-30 RLG, RB510SM-30T2R, and RB511SM-30T2R are all ROHS3 compliant. The original CDBP0130R-G RoHS status was not specified.

Q: Are there any temperature rating differences between the original and substitute parts?

A: The original CDBP0130R-G and RB511SM-30T2R both have 125°C maximum junction temperature. RB520G-30 RLG also has 125°C maximum. RB510SM-30T2R offers extended rating at 150°C maximum, providing additional thermal margin for high-temperature environments.
