S2DA-13 Equivalent & Substitute Parts

Part Overview

The S2DA-13 is a general-purpose rectifier diode manufactured by Diodes Incorporated, rated for 200 V DC reverse voltage and 1.5 A average rectified current in a surface mount SMA (DO-214AC) package. This part is discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design support and production requirements. Equivalent parts maintain identical electrical specifications, while substitute parts provide functional alternatives with modified parameters within acceptable application ranges.

Substitute Part Grouping Explanation

Substitution of the S2DA-13 is determined by the following critical parameters: voltage rating (200 V DC reverse), current rating (1.5 A average rectified), package type (DO-214AC/SMA surface mount), and forward voltage characteristics. Parts are grouped into three categories based on substitution relationship:

Parametric Equivalent (Identical Specifications): Parts maintaining 200 V, 1.5 A ratings with matching forward voltage and recovery characteristics.

Manufacturer Recommended - Avalanche Technology: Parts with 200 V, 1.5 A ratings but employing avalanche diode technology, resulting in modified forward voltage and faster recovery times.

Manufacturer Recommended - Current Variants: Parts with 200 V voltage rating but different current ratings (1 A or 2 A), suitable for applications where current requirements differ from the original specification.

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalent): The S2DA-13-F is the primary equivalent, manufactured by Diodes Incorporated with identical electrical specifications (200 V, 1.5 A, 1.15 V forward voltage). This part is active and ROHS3 compliant, addressing the RoHS non-compliance status of the original S2DA-13. The S2DA-13-F is available in Tape & Reel packaging and represents the most direct substitution path.

Active Alternatives with Modified Characteristics: The STTH1R02A (STMicroelectronics) maintains the 200 V, 1.5 A rating with improved forward voltage (1 V @ 1.5 A) and faster recovery characteristics (30 ns). This part is active and ROHS3 compliant. The BYG20D-E3/TR and BYG20D-E3/TR3 (Vishay) provide 200 V, 1.5 A ratings with avalanche technology, resulting in higher forward voltage (1.4 V @ 1.5 A) but superior reverse leakage performance (1 µA @ 200 V).

Current-Rated Alternatives: The STTH102A and STTH102AY are rated for 1 A average rectified current at 200 V, suitable for applications with reduced current requirements. The STTH2R02A is rated for 2 A at 200 V, applicable to designs requiring higher current capacity. All three are active and ROHS3 compliant.

Obsolete Parts: The CSA2D-E3/I (Vishay) is marked obsolete and should not be selected for new designs despite ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the S2DA-13-F be used as a direct replacement for the S2DA-13?

A: Yes. The S2DA-13-F is a parametric equivalent with identical voltage (200 V), current (1.5 A), forward voltage (1.15 V @ 1.5 A), and recovery characteristics. The primary difference is packaging format (Tape & Reel versus bulk) and improved RoHS compliance status. Both use the DO-214AC/SMA package.

Q: What is the difference between the S2DA-13 and STTH1R02A?

A: Both parts are rated 200 V, 1.5 A in DO-214AC/SMA packages. The STTH1R02A features lower forward voltage (1 V @ 1.5 A versus 1.15 V) and faster recovery time (30 ns versus >500ns standard recovery). The STTH1R02A is manufactured by STMicroelectronics and is active with ROHS3 compliance.

Q: Can I use a 1 A rated diode (STTH102A or STTH102AY) in place of the 1.5 A S2DA-13?

A: Only if the application circuit requires maximum 1 A average rectified current. The STTH102A and STTH102AY are rated for 1 A and will not safely handle 1.5 A continuous current. Both maintain the 200 V voltage rating and DO-214AC/SMA package compatibility.

Q: What is the difference between STTH102A and STTH102AY?

A: Both parts are electrically identical with 200 V, 1 A ratings, 970 mV forward voltage, and fast recovery characteristics. The STTH102AY is designated as automotive grade (Series Q) with operating temperature range -40°C to 175°C, compared to the standard STTH102A with maximum junction temperature of 175°C. Both are ROHS3 compliant and active.

Q: Why do the BYG20D-E3/TR and BYG20D-E3/TR3 have higher forward voltage than the original S2DA-13?

A: The BYG20D series employs avalanche diode technology, which results in higher forward voltage (1.4 V @ 1.5 A) compared to standard rectifier technology (1.15 V @ 1.5 A). This technology trade-off provides superior reverse leakage performance (1 µA versus 5 µA) and faster recovery characteristics (75 ns).

Q: Are all substitute parts available in the same package as the S2DA-13?

A: Yes. All listed substitute parts use the DO-214AC/SMA surface mount package, ensuring mechanical and electrical compatibility with existing PCB layouts. Packaging format variations (Cut Tape, Tape & Reel) do not affect component functionality.

Q: What is the significance of RoHS compliance for the S2DA-13 substitution?

A: The original S2DA-13 is RoHS non-compliant. All active substitute parts (S2DA-13-F, BYG20D series, STTH series) are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Can the STTH2R02A (2 A rated) be used in place of the S2DA-13 (1.5 A rated)?

A: Yes, from a current capacity perspective. The STTH2R02A is rated for 2 A at 200 V, exceeding the 1.5 A requirement of the original part. Both use DO-214AC/SMA packages. The STTH2R02A features lower forward voltage (1 V @ 2 A) and faster recovery (30 ns). This substitution is suitable for applications where higher current margin is acceptable.
