Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS23LHRVG are qualified based on the following electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 30 V
• Technology: Must be Schottky diode type
• Speed: Must maintain Fast Recovery ≤ 500ns, > 200mA (Io)
• Package / Case: Must be DO-219AB (mechanical and thermal compatibility)
• Mounting Type: Must be Surface Mount

Mechanical Compatibility Criteria:

• Supplier Device Package: Must be compatible with DO-219AB (SMF) footprint
• Mounting Type: Surface Mount requirement

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• Product Status: Active

The substitute parts SL03-GS18 and SL03-M-08 meet these criteria. Both are Vishay General Semiconductor Schottky diodes rated for 30 V DC reverse voltage with DO-219AB packaging and Fast Recovery characteristics. Current rating differences (1.1 A versus 2 A) represent a derating condition where the substitute operates within reduced current specifications, which is acceptable for applications not requiring the full 2 A capacity of the main part.

Parameter Comparison

Engineering Selection Recommendations

SS23LHRVG Selection Criteria: The SS23LHRVG is appropriate for applications requiring 2 A average rectified current at 30 V DC reverse voltage with automotive-grade reliability. The part carries AEC-Q101 qualification and operates across the extended temperature range of -55°C to 150°C, suitable for demanding automotive and industrial environments.

SL03-GS18 and SL03-M-08 Selection Criteria: Both Vishay substitute parts are appropriate for applications where current requirements do not exceed 1.1 A at 30 V DC reverse voltage. These parts maintain equivalent voltage ratings, Schottky technology, and Fast Recovery characteristics. Both are ROHS3 compliant and REACH unaffected. The primary difference between SL03-GS18 and SL03-M-08 is packaging format: SL03-GS18 is supplied in Tape & Reel (TR), while SL03-M-08 is supplied in Cut Tape (CT) & Digi-Reel®.

Substitution Limitations: The substitute parts operate at reduced maximum junction temperature (125°C versus 150°C) and lower average rectified current (1.1 A versus 2 A). These characteristics must be evaluated against application thermal and current requirements. The substitute parts exhibit lower reverse leakage current (130 µA versus 400 µA at 30 V) and lower forward voltage drop (430 mV versus 500 mV at rated current), which may provide performance benefits in specific circuit topologies.

Frequently Asked Questions (FAQ)

Q: Can SL03-GS18 or SL03-M-08 be used as direct replacements for SS23LHRVG in all applications?

A: Direct substitution is limited by current rating. The substitute parts are rated for 1.1 A average rectified current, while the SS23LHRVG is rated for 2 A. Substitution is valid only for applications where the actual circuit current does not exceed 1.1 A. Additionally, the maximum junction temperature of the substitutes is 125°C compared to 150°C for the main part, which must be considered in thermal design.

Q: What is the difference between SL03-GS18 and SL03-M-08?

A: Both parts are electrically identical Vishay Schottky diodes with 30 V rating and 1.1 A current capacity. The difference is packaging format: SL03-GS18 is supplied in Tape & Reel (TR) format, while SL03-M-08 is supplied in Cut Tape (CT) & Digi-Reel® format. Selection between these two depends on manufacturing process requirements and inventory management practices.

Q: Are the substitute parts automotive qualified?

A: The provided data does not specify automotive qualification or AEC-Q101 status for the substitute parts. The SS23LHRVG carries explicit AEC-Q101 automotive qualification. Applications requiring automotive-grade components must confirm qualification status with the manufacturer before substitution.

Q: What are the implications of lower reverse leakage current in the substitute parts?

A: The substitute parts exhibit 130 µA reverse leakage at 30 V compared to 400 µA for the main part. Lower reverse leakage current generally reduces power dissipation in reverse bias conditions and may improve circuit performance in applications sensitive to leakage current, such as precision analog circuits or low-power standby modes.

Q: Are both substitute parts RoHS and REACH compliant?

A: Yes. Both SL03-GS18 and SL03-M-08 are ROHS3 compliant and REACH unaffected, matching the compliance status of the SS23LHRVG.

Q: What is the significance of the DO-219AB package designation?

A: DO-219AB is the standardized package designation for surface mount Schottky diodes in the SMF (Sub Miniature Flat) form factor. All three parts (main and substitutes) use this package, ensuring mechanical and thermal compatibility on printed circuit boards. The Sub SMA designation for the SS23LHRVG refers to the same physical package.
