SS23LHRTG Equivalent & Substitute Parts

Part Overview

The SS23LHRTG is an active 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 designed for fast recovery applications with forward voltage of 500 mV at 2A and operates across a junction temperature range of -55°C to 150°C. The part carries AEC-Q101 automotive qualification and is ROHS3 compliant.

Equivalent and substitute parts are identified when alternative components share identical or compatible electrical ratings, mechanical packaging, and thermal specifications, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS23LHRTG is determined by strict equivalence across the following critical parameters:

Voltage Rating: The substitute part must maintain a DC reverse voltage rating of 30V or greater to ensure safe operation under maximum reverse bias conditions.

Current Rating: The substitute part must support the required average rectified current. The SS23LHRTG is rated for 2A; substitute parts with equal or higher current capacity are acceptable.

Package and Mounting: Both the main part and substitute must use the DO-219AB package with surface mount technology to ensure mechanical and electrical compatibility with existing PCB layouts.

Technology Type: Both components must be Schottky diodes to maintain identical switching characteristics and forward voltage behavior.

Recovery Speed: Fast recovery characteristics (≤ 500ns for currents > 200mA) must be preserved in substitute parts.

Compliance Standards: Substitute parts must maintain ROHS3 compliance and automotive-grade qualification where applicable.

The SL03-GS18 from Vishay General Semiconductor meets the voltage, package, technology, and recovery speed requirements. However, its current rating of 1.1A is lower than the SS23LHRTG's 2A rating, which restricts its application scope.

Parameter Comparison

Engineering Selection Recommendations

Primary Application Suitability: The SS23LHRTG is the specified component for applications requiring 2A rectified current capacity. Selection of this part is appropriate for designs operating within the -55°C to 150°C junction temperature range and requiring AEC-Q101 automotive qualification.

Substitute Applicability: The SL03-GS18 is suitable as a substitute only in applications where the required average rectified current does not exceed 1.1A. This substitute part maintains equivalent voltage ratings, package compatibility, and fast recovery characteristics. The SL03-GS18 operates to a maximum junction temperature of 125°C, which is acceptable for applications not requiring the full -55°C to 150°C range of the main part.

Compliance Considerations: Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard manufacturing and storage protocols. The main part carries explicit AEC-Q101 automotive qualification; the substitute part's automotive qualification status should be verified for safety-critical automotive applications.

Thermal Performance: The SL03-GS18 exhibits lower reverse leakage current (130 µA versus 400 µA at 30V), which may provide improved thermal performance in low-current standby conditions. However, the reduced maximum junction temperature rating limits its use in high-temperature environments.

Frequently Asked Questions (FAQ)

Q: Can the SL03-GS18 directly replace the SS23LHRTG in all applications?

A: The SL03-GS18 is a direct mechanical and electrical substitute only for applications where the average rectified current requirement does not exceed 1.1A. The SS23LHRTG's 2A rating cannot be matched by the SL03-GS18. Additionally, applications requiring operation above 125°C junction temperature must use the SS23LHRTG.

Q: What are the key differences between these two parts?

A: The primary differences are current rating (2A versus 1.1A), maximum junction temperature (150°C versus 125°C), and reverse leakage current (400 µA versus 130 µA at 30V). Both parts share identical voltage ratings, package type, and fast recovery characteristics.

Q: Are both parts in the same package?

A: Yes. Both the SS23LHRTG and SL03-GS18 use the DO-219AB surface mount package, ensuring identical PCB footprint and mounting compatibility.

Q: Does the SL03-GS18 have automotive qualification?

A: The SL03-GS18 is manufactured by Vishay General Semiconductor and carries ROHS3 compliance. The specific AEC-Q101 automotive qualification status of the SL03-GS18 is not provided in the available technical parameters and must be confirmed through the manufacturer's documentation.

Q: What is the significance of the lower reverse leakage current in the SL03-GS18?

A: Lower reverse leakage current (130 µA versus 400 µA) indicates reduced parasitic current flow under reverse bias conditions. This characteristic may reduce power dissipation and heat generation in standby or low-current operating modes.

Q: Can I use the SS23LHRTG as a substitute for the SL03-GS18?

A: Yes. The SS23LHRTG can be used as a substitute for the SL03-GS18 in all applications. The SS23LHRTG provides higher current capacity (2A versus 1.1A) and extended temperature range (-55°C to 150°C versus maximum 125°C), making it suitable for more demanding operating conditions.

Q: What is the difference between Sub SMA and DO-219AB package designations?

A: Sub SMA and DO-219AB refer to the same physical package form. Sub SMA is the supplier device package designation used by Taiwan Semiconductor Corporation, while DO-219AB is the standardized industry package classification. Both designations describe an identical surface mount package footprint.
