S3M General Purpose Rectifier Diode Equivalent & Substitute Parts

Part Overview

The S3M is a general purpose rectifier diode rated for 1000 V DC reverse voltage and 3 A average rectified current in a surface mount DO-214AB (SMC) package. This component is designed for standard recovery applications with a reverse recovery time of 1.5 µs. The part is currently in active production status with multiple manufacturers offering equivalent designs. Substitute parts are identified when manufacturers discontinue production, inventory becomes unavailable, or alternative sourcing is required for supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S3M rectifier diode are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) Maximum: 1000 V
• Current - Average Rectified (Io): 3 A
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Speed Classification: Standard Recovery >500ns, > 200mA (Io)
• Reverse Recovery Time (trr): 1.5 µs

All substitute parts listed maintain these core electrical specifications and physical package requirements, ensuring direct functional equivalence in circuit applications. Variations in secondary parameters such as forward voltage, reverse leakage current, and capacitance do not disqualify substitution when primary ratings remain identical.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed maintain active production status and are qualified as direct substitutes based on matching electrical ratings and package specifications. Selection between manufacturers should be based on the following factors:

Taiwan Semiconductor Corporation S3M:

• RoHS3 Compliant
• REACH Unaffected
• Moisture Sensitivity Level 1 (Unlimited)
• Inventory: 3713 pieces

Diotec Semiconductor S3M:

• RoHS Status: Not applicable
• REACH Status: Vendor Undefined
• Moisture Sensitivity Level: Not Applicable
• Inventory: 9293 pieces
• Lower reverse leakage current (5 µA vs. 10 µA)
• Forward voltage specification provided (1.15 V @ 3 A)

Panjit International Inc. S3M_R1_00001:

• RoHS3 Compliant
• REACH Unaffected
• Moisture Sensitivity Level 1 (Unlimited)
• Inventory: 1945 pieces
• Lowest reverse leakage current (1 µA @ 1000 V)
• Capacitance specification provided (53 pF @ 4V, 1MHz)
• Packaging: Tape & Reel (TR)

All parts share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications. Component selection should prioritize compliance requirements and inventory availability for your specific application.

Frequently Asked Questions (FAQ)

Q: Can the Diotec Semiconductor S3M be used as a direct replacement for the Taiwan Semiconductor Corporation S3M?

A: Yes. Both parts are rated for 1000 V DC reverse voltage, 3 A average rectified current, and use the DO-214AB (SMC) surface mount package. Electrical specifications including reverse recovery time (1.5 µs) and speed classification are identical. The Diotec part exhibits lower reverse leakage current (5 µA vs. 10 µA), which is a favorable characteristic for circuit performance.

Q: What is the difference between the S3M_R1_00001 from Panjit International and the S3M from Taiwan Semiconductor?

A: Both parts meet the same electrical ratings (1000 V, 3 A, 1.5 µs trr) and use the DO-214AB (SMC) package. The primary difference is packaging format: Panjit supplies in Tape & Reel (TR) format, while Taiwan Semiconductor offers Cut Tape (CT) & Digi-Reel® options. The Panjit part has superior reverse leakage characteristics (1 µA vs. 10 µA) and provides capacitance specification data.

Q: Are there temperature range differences between these substitute parts?

A: The Taiwan Semiconductor S3M and Panjit S3M_R1_00001 both operate from -55°C to 150°C junction temperature. The Diotec S3M operates from -50°C to 150°C, providing a 5°C narrower lower temperature range. For applications requiring operation below -50°C, the Taiwan Semiconductor or Panjit parts are required.

Q: Do all substitute parts have the same RoHS and REACH compliance status?

A: No. The Taiwan Semiconductor S3M and Panjit S3M_R1_00001 are both RoHS3 Compliant and REACH Unaffected. The Diotec S3M has RoHS Status listed as "Not applicable" and REACH Status as "Vendor Undefined." Compliance requirements for your application should determine part selection.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, from an electrical and mechanical standpoint. All three parts use the DO-214AB (SMC) surface mount package with identical pinout and footprint. However, packaging format differs: Taiwan Semiconductor and Diotec offer Cut Tape (CT) & Digi-Reel® options, while Panjit supplies Tape & Reel (TR). Verify your assembly equipment compatibility with the selected packaging format.

Q: Which substitute part has the best reverse leakage characteristics?

A: The Panjit International S3M_R1_00001 exhibits the lowest reverse leakage current at 1 µA @ 1000 V, compared to 5 µA for Diotec and 10 µA for Taiwan Semiconductor. Lower reverse leakage reduces standby current consumption and improves circuit efficiency in applications sensitive to leakage current.

Q: Are forward voltage specifications available for all parts?

A: Forward voltage specifications are provided for the Diotec S3M (1.15 V @ 3 A) and Panjit S3M_R1_00001 (1.2 V @ 3 A). The Taiwan Semiconductor S3M does not include forward voltage data in the provided specifications. For applications where forward voltage drop is critical, the Diotec part offers the lowest specification at 1.15 V.
