S1M-F Equivalent & Substitute Parts

Part Overview

The S1M-F is a general-purpose rectifier diode rated for 1000 V DC reverse voltage and 1 A average rectified current in a surface mount SMA (DO-214AC) package. Manufactured by SMC Diode Solutions, this component is classified as obsolete. Due to its obsolete status and limited availability from the original manufacturer, identifying equivalent substitute parts with matching electrical and mechanical specifications is necessary for design continuity and procurement flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S1M-F are qualified based on the following critical parameters:

• Voltage Rating: DC reverse voltage of 1000 V (maximum)
• Current Rating: Average rectified current of 1 A
• Forward Voltage: Maximum 1.1 V at 1 A forward current
• Package Type: Surface mount DO-214AC (SMA) form factor
• Mounting Compatibility: Surface mount technology
• Temperature Range: Operating junction temperature capability

Substitute parts must meet or exceed these electrical specifications and maintain mechanical compatibility with the DO-214AC/SMA package footprint. Parts are grouped as parametric equivalents when all critical parameters align within the specified tolerances.

Parameter Comparison

Engineering Selection Recommendations

GS1M (SURGE): This part is an active product with all critical electrical parameters matching the S1M-F. The GS1M demonstrates improved performance characteristics including lower reverse recovery time (1 µs versus 2.5 µs) and reduced reverse leakage current (1 µA versus 5 µA). The operating temperature range is narrower (-55°C to 150°C versus -65°C to 175°C). The GS1M carries RoHS3 compliance certification. Selection of the GS1M is appropriate for applications where the narrower temperature range is acceptable and where improved switching characteristics provide system benefits.

S1M (EVVO Semi): This part is an active product with all critical electrical parameters matching the S1M-F. The S1M maintains identical reverse leakage current (5 µA) and capacitance (15 pF) specifications. The operating temperature range is narrower (-55°C to 150°C versus -65°C to 175°C). The S1M carries RoHS3 compliance certification. Selection of the S1M is appropriate for applications where the narrower temperature range is acceptable and where parameter alignment with the original part is prioritized.

Both substitute parts are surface mount compatible with the DO-214AC/SMA package and maintain the same voltage and current ratings. The choice between GS1M and S1M depends on application-specific requirements regarding reverse recovery time, leakage current performance, and operating temperature constraints.

Frequently Asked Questions (FAQ)

Q: Can the GS1M or S1M be used as direct replacements for the S1M-F?

A: Both the GS1M and S1M meet the critical electrical specifications of the S1M-F: 1000 V reverse voltage rating, 1 A average rectified current, 1.1 V forward voltage at 1 A, and DO-214AC/SMA surface mount package compatibility. Both are qualified as parametric equivalents. However, the operating temperature range is reduced from -65°C to 175°C to -55°C to 150°C. Verify that your application does not require operation below -55°C or above 150°C.

Q: What is the difference between the GS1M and S1M?

A: Both parts share identical voltage and current ratings. The GS1M offers superior switching performance with a reverse recovery time of 1 µs compared to the S1M-F specification of 2.5 µs, and lower reverse leakage current of 1 µA versus 5 µA. The S1M maintains the same reverse leakage current as the S1M-F (5 µA) and does not specify reverse recovery time. Both have identical capacitance and package specifications.

Q: Are there any packaging differences between these parts?

A: All three parts use the DO-214AC/SMA surface mount package. The S1M-F and S1M are supplied in Cut Tape (CT) and Digi-Reel® packaging. The GS1M is supplied in Bag packaging. The physical component footprint and land pattern are identical across all three parts, ensuring PCB compatibility.

Q: What compliance certifications apply to the substitute parts?

A: The GS1M carries RoHS3 compliance certification. The S1M carries RoHS3 compliance certification. Both parts have MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling.

Q: How do the temperature ranges compare?

A: The S1M-F operates from -65°C to 175°C junction temperature. Both the GS1M and S1M operate from -55°C to 150°C junction temperature. If your application requires operation below -55°C or above 150°C, the substitute parts are not suitable.

Q: Are there inventory considerations for these parts?

A: The S1M-F has 60,300 pieces in stock but is classified as obsolete. The GS1M has 77,200 pieces in stock and is active. The S1M has 5,394 pieces in stock and is active. For long-term procurement, the active status of GS1M and S1M provides greater supply chain stability.
