SS23LHRQG Equivalent & Substitute Parts

Part Overview

The SS23LHRQG is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 30V DC reverse voltage and 2A average rectified current in a Sub SMA surface mount package. This component is classified as Active product status with AEC-Q101 automotive qualification and ROHS3 compliance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to component availability, supply chain considerations, or design flexibility within specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS23LHRQG is determined by equivalence in the following critical parameters:

Electrical Compatibility Requirements:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 30V
• Technology: Must be Schottky diode type
• Speed: Must meet Fast Recovery specification ≤ 500ns, > 200mA (Io)
• Package / Case: Must be DO-219AB or equivalent Sub SMA form factor
• Mounting Type: Must be Surface Mount

Mechanical Compatibility Requirements:

• Package / Case: DO-219AB (Sub SMA)
• Mounting Type: Surface Mount

Compliance Requirements:

• RoHS Status: ROHS3 Compliant
• Technology: Schottky rectifier diode

The substitute part SL03-GS18 meets these criteria with equivalent reverse voltage rating (30V), Schottky technology, fast recovery speed characteristic, and identical DO-219AB package configuration. Current rating differences are noted in the parameter comparison table below.

Engineering Selection Recommendations

SS23LHRQG Selection Criteria: The SS23LHRQG is suitable for applications requiring 2A average rectified current at 30V reverse voltage with automotive-grade reliability. This part carries AEC-Q101 qualification, indicating compliance with automotive industry standards. ROHS3 compliance and unlimited moisture sensitivity level (MSL 1) support deployment in regulated manufacturing environments.

SL03-GS18 Selection Criteria: The SL03-GS18 is suitable for applications where current requirements do not exceed 1.1A at 30V reverse voltage. This substitute part maintains Schottky technology, fast recovery speed, and DO-219AB package compatibility. ROHS3 compliance and unlimited MSL rating provide equivalent environmental compliance. The lower reverse leakage current (130 µA versus 400 µA) and specified reverse recovery time (10 ns) represent measurable performance characteristics. Maximum junction temperature is rated at 125°C compared to 150°C for the main part.

Substitution Applicability: The SL03-GS18 functions as a substitute only in circuit designs where the average rectified current requirement does not exceed 1.1A. Both parts share identical reverse voltage rating, Schottky technology, fast recovery speed classification, and DO-219AB package configuration. Both maintain Active product status and ROHS3 compliance. Selection between these parts depends on circuit current requirements and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the SL03-GS18 directly replace the SS23LHRQG in all applications?

A: The SL03-GS18 is a direct substitute only in applications where the average rectified current does not exceed 1.1A. The SS23LHRQG is rated for 2A, while the SL03-GS18 is rated for 1.1A. If your circuit requires current above 1.1A, the SL03-GS18 is not suitable. Both parts share identical 30V reverse voltage rating, Schottky technology, fast recovery speed, and DO-219AB package configuration.

Q: Are the packages physically identical?

A: Both parts use the DO-219AB package in surface mount configuration. The SS23LHRQG is designated as Sub SMA, while the SL03-GS18 is designated as DO-219AB (SMF). These designations refer to the same physical package form factor and are mechanically compatible for PCB assembly.

Q: What is the difference in forward voltage drop?

A: The SS23LHRQG specifies 500 mV maximum forward voltage at 2A, while the SL03-GS18 specifies 430 mV maximum forward voltage at 1.1A. Forward voltage characteristics are current-dependent and cannot be directly compared across different current ratings. At equivalent current levels, the SL03-GS18 exhibits lower forward voltage drop.

Q: Do both parts meet automotive qualification requirements?

A: The SS23LHRQG carries AEC-Q101 automotive qualification. The SL03-GS18 does not list AEC-Q101 qualification in the provided specifications. If automotive qualification is a design requirement, the SS23LHRQG is the specified part. Both parts are ROHS3 compliant and REACH unaffected.

Q: What is the reverse leakage current difference?

A: The SS23LHRQG specifies 400 µA reverse leakage at 30V, while the SL03-GS18 specifies 130 µA reverse leakage at 30V. The SL03-GS18 exhibits lower reverse leakage current. This parameter affects power dissipation in reverse bias conditions and may be relevant in low-power or high-impedance circuit applications.

Q: Are there temperature rating differences?

A: The SS23LHRQG maximum junction temperature is 150°C, while the SL03-GS18 maximum junction temperature is 125°C. The SS23LHRQG supports higher thermal operating conditions. If your application operates near or above 125°C junction temperature, the SS23LHRQG is required.

Q: What does the reverse recovery time specification mean?

A: The SL03-GS18 specifies reverse recovery time (trr) of 10 ns. This parameter indicates the time required for the diode to transition from forward conduction to reverse blocking state. The SS23LHRQG does not provide a specific trr value but meets the Fast Recovery speed classification (≤ 500ns, > 200mA). Both parts are classified as fast recovery diodes suitable for high-frequency switching applications.
