Key Parameters

Substitute Part Grouping Explanation

Substitution of the RB520G-30-TP is determined by the following critical parameters:

Voltage Rating: All substitute parts must maintain a maximum DC reverse voltage of 30 V or greater to ensure circuit protection and reliability.

Current Rating: Substitute parts must support the 100 mA average rectified current requirement or higher. Parts with higher current ratings remain compatible with circuits designed for 100 mA operation.

Technology: All substitutes are Schottky diodes, maintaining the same rectification characteristics and forward voltage behavior required for the application.

Mounting Type: All substitutes are surface mount devices compatible with automated assembly processes.

Package Compatibility: Substitutes are grouped into two package categories: SOD-723 (direct package equivalent) and EMD2/SOD-523 (alternative surface mount packages with compatible footprints for redesign scenarios).

Compliance: All substitutes maintain ROHS3 compliance and MSL 1 rating, ensuring environmental and moisture handling compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Parametric Match):

RB520G-30 RLG from Taiwan Semiconductor Corporation provides an identical parametric match to the RB520G-30-TP. This part maintains the same voltage rating, current rating, forward voltage characteristics, reverse leakage, SOD-723 package, and junction temperature rating. The part is currently active in production with established supply availability.

Alternative Substitutes (Functional Compatibility):

RB511SM-30T2R and RB510SM-30T2R from Rohm Semiconductor are functionally compatible substitutes with identical voltage and current ratings. Both parts are active and available in higher quantities. These parts utilize the EMD2 package (SOD-523 equivalent), requiring PCB layout modification. RB510SM-30T2R offers superior reverse leakage performance (300 nA) and higher junction temperature rating (150°C). RB511SM-30T2R provides lower forward voltage (370 mV @ 10 mA) compared to the original specification.

Higher Current Capacity Substitute:

CDBER0230R from Comchip Technology is rated for 200 mA average rectified current, providing increased current capacity while maintaining the 30 V voltage rating. This part is suitable for applications requiring design margin or future current expansion. The 0503 package requires PCB redesign. Forward voltage is specified at 200 mA operation (600 mV), differing from the 10 mA reference point of other parts.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with existing manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can RB520G-30 RLG be used as a direct replacement for RB520G-30-TP?

A: Yes. RB520G-30 RLG provides identical electrical parameters, package type (SOD-723), and thermal rating. No circuit or PCB modifications are required. This is the recommended direct equivalent.

Q: What is the difference between SOD-723 and EMD2 packages?

A: SOD-723 and EMD2 (SOD-523) are different surface mount package outlines with different footprints. Direct substitution between these packages requires PCB layout modification. RB520G-30 RLG maintains the SOD-723 package, eliminating this requirement.

Q: Can CDBER0230R replace RB520G-30-TP in existing designs?

A: CDBER0230R is electrically compatible (30 V rating, 100 mA minimum operation) but uses a 0503 package requiring PCB redesign. The higher 200 mA current rating provides design margin. Forward voltage is specified at different operating conditions (600 mV @ 200 mA versus 450 mV @ 10 mA), requiring circuit analysis for applications sensitive to forward voltage characteristics.

Q: What are the advantages of RB510SM-30T2R over the original part?

A: RB510SM-30T2R offers lower reverse leakage current (300 nA versus 500 nA), higher junction temperature rating (150°C versus 125°C), and higher production availability (56,300 units in stock). The EMD2 package requires PCB modification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with environmental regulations and manufacturing standards.

Q: Which substitute part has the lowest forward voltage?

A: RB511SM-30T2R specifies 370 mV @ 10 mA forward voltage, lower than the original 450 mV specification. This part is suitable for applications where minimizing forward voltage drop is beneficial.

Q: Can substitute parts be mixed in the same design?

A: Mixing different package types (SOD-723 versus EMD2/SOD-523) within a single PCB design is not recommended without separate footprint provisions. Electrical parameter variations between parts should be evaluated for circuit-specific requirements.
