S1FLB-GS08 Equivalent & Substitute Parts Reference

Part Overview

The S1FLB-GS08, manufactured by Vishay General Semiconductor - Diodes Division, is a surface mount general purpose diode rated for 100V and 700mA in a DO-219AB package. It features standard recovery characteristics, low reverse leakage, and is RoHS3 compliant. The active status of this diode and its role in rectification and general-purpose applications necessitate the identification of alternative models for cases where sourcing flexibility, inventory, or supply continuity across different distributors and manufacturers is required.

Key Parameters

Substitute Part Grouping Explanation

The substitute parts for S1FLB-GS08 are selected strictly based on alignment of the provided electrical and mechanical parameters: reverse voltage rating, average forward current, package, forward voltage, recovery speed, reverse leakage, capacitance, and compliance status (RoHS, REACH). Only components that match these key characteristics within the provided specifications, and maintain similar compliance or certification status, are included in the substitute group.

Key parameters for grouping:

• Voltage – DC Reverse (Vr) (Max)
• Current – Average Rectified (Io)
• Voltage – Forward (Vf) (Max) @ If
• Package / Case and Mounting Type
• Reverse Recovery Time (trr)
• Reverse Leakage Current
• Capacitance
• Compliance (RoHS, REACH)
• Operating Temperature – Junction (if provided)

Engineering Selection Recommendations

Selection of substitute rectifier diodes for S1FLB-GS08 should be based on part status and available compliance information. Both S1FLB-GS08 and S1FLB-M-08 are active products and feature ROHS3 compliance and REACH unaffected status, matching those of the target part. The S1BL is not for new designs, though it maintains the same compliance status. All listed products maintain an MSL of 1 (Unlimited), ensuring compatibility in typical electronic assembly environments.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to determine if a diode is a suitable substitute for S1FLB-GS08?
A1: Substitute diodes are determined by matching electrical parameters such as maximum reverse voltage, forward current, forward voltage drop, reverse recovery time, reverse leakage, capacitance, and maintaining the same package type and compliance status.

Q2: Are all suggested substitutes form-fit-function compatible?
A2: Only parts with the same DO-219AB package and surface mount configuration are included to ensure physical compatibility.

Q3: How does compliance (RoHS, REACH) affect substitute selection?
A3: Only diodes with the same or higher environmental compliance (ROHS3 Compliant, REACH Unaffected) are included to satisfy regulatory requirements.

Q4: Why is part status important when selecting a substitute?
A4: Active and in-production parts are favored to ensure long-term availability. Parts listed as not recommended for new designs may be suitable for maintenance but are generally excluded for new development.

Q5: Can differences in reverse leakage or capacitance affect substitution?
A5: Substitutes are only listed if their reverse leakage current and capacitance at rated voltage and test frequency are within the specified values provided.

Q6: What is the importance of matching MSL (Moisture Sensitivity Level)?
A6: A matching MSL ensures handling and storage requirements align with assembly and reliability processes, supporting direct interchangeability.
