Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S1GL RUG are identified based on the following electrical and mechanical criteria:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 400 V minimum
• Package / Case: DO-219AB (Sub SMA or equivalent)
• Mounting Type: Surface Mount
• Technology: Standard recovery rectifier diode
• RoHS Status: ROHS3 Compliant

Secondary Compatibility Factors:

• Current - Average Rectified (Io): Equal or greater rating
• Reverse Recovery Time (trr): 1.8 µs or faster
• Operating Temperature Range: Minimum -55°C to 150°C or higher
• Voltage - Forward (Vf): 1.1 V or lower at rated current

The S1GL part number from Taiwan Semiconductor Corporation is classified as a parametric equivalent with identical electrical specifications. The S07G-GS08 and S07G-GS18 from Vishay General Semiconductor are classified as similar alternatives with reduced current rating (700 mA versus 1 A) but equivalent voltage and recovery characteristics.

Parameter Comparison

Engineering Selection Recommendations

S1GL (Parametric Equivalent): The S1GL part number is electrically and mechanically identical to the S1GL RUG main part. Both components share identical voltage, current, and thermal specifications. The S1GL carries a "Not For New Designs" product status designation, indicating it is in mature or declining production phase. Selection of this substitute is appropriate for legacy system maintenance and repair applications where component continuity is required. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level.

S07G-GS08 and S07G-GS18 (Similar Alternatives): The S07G-GS08 and S07G-GS18 from Vishay General Semiconductor are similar alternatives with reduced average rectified current rating of 700 mA compared to the 1 A rating of the S1GL RUG. These components are suitable for applications where the circuit current requirement does not exceed 700 mA. Both Vishay alternatives carry Active product status and include AEC-Q101 automotive qualification. The operating temperature range is reduced to -55°C to 150°C compared to the S1GL RUG range of -55°C to 175°C. All three substitute options maintain identical 400 V reverse voltage rating, 1.8 µs reverse recovery time, and DO-219AB package compatibility.

Selection between S07G-GS08 and S07G-GS18 depends on reverse leakage current specifications at different voltage levels. The S07G-GS08 specifies 10 µA @ 400 V, while the S07G-GS18 specifies 10 µA @ 200 V.

Frequently Asked Questions (FAQ)

Q: Can the S1GL substitute directly for the S1GL RUG in new designs?

A: The S1GL is electrically identical to the S1GL RUG but carries a "Not For New Designs" product status. For new designs, the S1GL RUG (Active status) is the appropriate selection. The S1GL is suitable for replacement and repair of existing systems.

Q: What is the primary difference between the S1GL RUG and the Vishay S07G-GS08 / S07G-GS18 alternatives?

A: The primary difference is the average rectified current rating. The S1GL RUG is rated for 1 A, while the S07G-GS08 and S07G-GS18 are rated for 700 mA. All three components share identical 400 V reverse voltage rating and 1.8 µs reverse recovery time. The Vishay alternatives include automotive qualification (AEC-Q101) and have a reduced maximum operating temperature of 150°C versus 175°C for the S1GL RUG.

Q: Are the S07G-GS08 and S07G-GS18 interchangeable with each other?

A: The S07G-GS08 and S07G-GS18 are mechanically and electrically similar. The difference lies in the reverse leakage current specification: S07G-GS08 specifies 10 µA @ 400 V, while S07G-GS18 specifies 10 µA @ 200 V. Both are suitable for identical applications where 700 mA current rating is sufficient.

Q: Can I use a 700 mA rated diode (S07G-GS08 or S07G-GS18) in place of a 1 A rated diode (S1GL RUG)?

A: Substitution is possible only if the circuit design current requirement does not exceed 700 mA. The 700 mA rated alternatives cannot be used in applications requiring sustained current above 700 mA. Circuit analysis must confirm that maximum operating current remains below the 700 mA limit.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The S1GL, S07G-GS08, and S07G-GS18 are all ROHS3 compliant. All parts maintain unlimited moisture sensitivity level (MSL 1).

Q: What is the package compatibility between the main part and substitutes?

A: All parts use the DO-219AB package in surface mount configuration. The S1GL RUG specifies "Sub SMA" as the supplier device package, while the Vishay alternatives specify "DO-219AB (SMF)". These designations refer to the same physical package and are mechanically compatible for PCB assembly.

Q: Which substitute should I select for automotive applications?

A: The S07G-GS08 and S07G-GS18 carry AEC-Q101 automotive qualification. If automotive qualification is a requirement, these Vishay alternatives are appropriate selections, provided the 700 mA current rating is sufficient for the application.
