S3D General Purpose Rectifier Diode 200V 3A DO-214AB

Part Overview

The S3D is a general purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 200V DC reverse voltage and 3A average rectified current in a surface mount DO-214AB (SMC) package. This component is currently in active production status with 3953 units in stock. The S3D serves as a standard recovery diode suitable for general rectification applications requiring moderate voltage and current ratings.

Substitute parts become necessary when the primary manufacturer part becomes unavailable, when alternative sourcing is required for supply chain continuity, or when design flexibility across multiple qualified suppliers is needed. The substitute identified in this reference maintains electrical and mechanical compatibility within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S3D is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) Maximum: 200V
• Current - Average Rectified (Io): 3A
• Package / Case: DO-214AB, SMC (surface mount)
• Mounting Type: Surface Mount
• Technology: Standard Recovery

Acceptable Variation Parameters:

• Reverse Recovery Time (trr): Substitute values must not exceed the main part specification to ensure switching performance compatibility
• Current - Reverse Leakage @ Vr: Substitute values must not exceed the main part specification
• Capacitance @ Vr: Substitute values must not exceed the main part specification
• Operating Temperature - Junction: Substitute range must encompass or exceed the main part range
• RoHS and REACH Compliance: Substitute must maintain equivalent compliance status

The S3D manufactured by Diodes Incorporated qualifies as a direct substitute based on matching voltage, current, and package specifications. Compliance certifications (ROHS3, REACH Unaffected, EAR99 ECCN) are equivalent between the main part and substitute.

Engineering Selection Recommendations

Primary Selection: S3D (Taiwan Semiconductor Corporation)

The Taiwan Semiconductor Corporation S3D is the recommended primary selection. This part maintains active production status with 3953 units currently in stock, ensuring supply availability and long-term support. All electrical and mechanical parameters meet application requirements for 200V, 3A rectification in surface mount form factor.

Substitute Selection: S3D (Diodes Incorporated)

The Diodes Incorporated S3D qualifies as a direct electrical and mechanical substitute. This part is rated for identical voltage (200V) and current (3A) specifications with the same DO-214AB SMC package. The substitute exhibits improved reverse recovery time (2µs versus 1.5µs) and lower junction capacitance (40pF versus 60pF), both favorable characteristics for switching performance. Operating temperature range extends to -65°C, exceeding the main part specification.

However, the Diodes Incorporated S3D carries obsolete product status with 1076 units in stock. Selection of this substitute should be limited to applications where supply chain continuity from this specific manufacturer is required or where the improved electrical characteristics provide measurable design benefit. For new designs, the active Taiwan Semiconductor Corporation part is preferred.

Both parts maintain equivalent RoHS3 compliance and REACH unaffected status, suitable for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the Diodes Incorporated S3D directly replace the Taiwan Semiconductor Corporation S3D in existing designs?

A: Yes. Both parts are rated for 200V reverse voltage and 3A average rectified current in identical DO-214AB SMC packages. Electrical parameters are compatible within specified tolerances. PCB layout and thermal management requirements remain unchanged.

Q: What is the significance of the reverse recovery time difference (1.5µs versus 2µs)?

A: Reverse recovery time affects switching speed and switching losses in rectification circuits. The Taiwan Semiconductor part exhibits faster recovery (1.5µs), which reduces reverse recovery charge and associated switching losses. The Diodes Incorporated substitute at 2µs remains within standard recovery classification (>500ns) and is suitable for general purpose applications. Applications with stringent switching loss requirements should specify the faster recovery time.

Q: Why does the Diodes Incorporated part show obsolete status?

A: Product status reflects current manufacturing availability from the supplier. Obsolete designation indicates the manufacturer has discontinued active production. Existing inventory (1076 units) may remain available through distribution channels, but long-term supply cannot be guaranteed. New designs should utilize the active Taiwan Semiconductor Corporation part.

Q: Are the capacitance values (60pF versus 40pF) significant for circuit design?

A: Capacitance at reverse voltage affects high-frequency performance and switching characteristics. The lower capacitance of the Diodes Incorporated substitute (40pF) provides improved performance at higher switching frequencies. For DC or low-frequency rectification applications, this difference is negligible. For switching power supplies or high-frequency circuits, the lower capacitance may provide measurable benefits.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the Taiwan Semiconductor Corporation S3D and Diodes Incorporated S3D are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification and identical HTSUS codes (8541.10.0080). Regulatory and environmental compliance requirements are equivalent.

Q: What is the moisture sensitivity level, and does it affect handling?

A: The Taiwan Semiconductor Corporation S3D carries MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling procedures for surface mount components apply. No special moisture control measures are required during storage or assembly.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Both parts are rated to 150°C junction temperature maximum. The Diodes Incorporated substitute extends the lower temperature limit to -65°C versus -55°C for the Taiwan Semiconductor part. For applications operating within -55°C to 150°C, both parts are suitable. Applications requiring operation below -55°C require the Diodes Incorporated substitute.
