DSEC16-02A Equivalent & Substitute Parts

Part Overview

The DSEC16-02A is a diode array rectifier manufactured by IXYS, configured as a 1 Pair Common Cathode design with 200 V reverse voltage rating and 8 A average rectified current per diode. The device is packaged in TO-220-3 through-hole format and operates across a junction temperature range of -55°C to 175°C. This part is classified as obsolete, necessitating identification of equivalent substitute components that maintain functional compatibility within modern supply chains while preserving circuit performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DSEC16-02A is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Voltage - DC Reverse (Vr) (Max): 200 V minimum
• Current - Average Rectified (Io) (per Diode): 8 A minimum
• Mounting Type: Through Hole
• Package / Case: TO-220-3

Allowable Variation Parameters:

• Voltage - Forward (Vf): Substitute values must not exceed the original specification under equivalent test conditions
• Reverse Recovery Time (trr): Substitute values up to 35 ns are acceptable within fast recovery classification
• Current - Reverse Leakage @ Vr: Lower values indicate improved performance
• Operating Temperature - Junction: Extended ranges are acceptable; minimum upper limit of 175°C required
• Product Status: Active status preferred for ongoing availability

All four substitute parts meet these mandatory criteria and are therefore electrically and mechanically compatible with the DSEC16-02A.

Parameter Comparison

Engineering Selection Recommendations

STTH1602CT (STMicroelectronics) is the primary substitute candidate. This part exceeds the current rating of the original device (10 A versus 8 A), provides improved forward voltage characteristics (1.1 V @ 8 A versus 1.3 V @ 8 A), and maintains reverse recovery time within acceptable limits (26 ns versus 25 ns). The device carries ROHS3 compliance certification and active product status, ensuring long-term availability and regulatory alignment.

STTH1002CT (STMicroelectronics) provides an exact current rating match (8 A) with identical reverse recovery time (25 ns) and improved reverse leakage characteristics (5 µA versus 50 µA). Forward voltage performance is equivalent at the specified test current. ROHS3 compliance and active status support modern supply chain requirements.

MUR1620CTG (onsemi) delivers current and voltage specifications matching the original device with superior forward voltage performance (975 mV @ 8 A). Extended operating temperature range (-65°C to 175°C) provides additional thermal margin. Reverse recovery time of 35 ns remains within fast recovery classification. ROHS3 compliance and active status confirm suitability for new designs.

BYV32-200G (onsemi) maintains identical electrical specifications to the DSEC16-02A with matching current rating (8 A) and reverse leakage (50 µA @ 200 V). Extended operating temperature range (-65°C to 175°C) and ROHS3 compliance support deployment in modern applications. Reverse recovery time of 35 ns remains within acceptable fast recovery parameters.

All four substitute parts are electrically and mechanically compatible with the DSEC16-02A. Selection should be based on circuit-specific requirements regarding forward voltage drop, reverse recovery characteristics, and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can STTH1602CT replace DSEC16-02A in all applications?

A: STTH1602CT is electrically compatible with DSEC16-02A. The higher current rating (10 A versus 8 A) and lower forward voltage (1.1 V @ 8 A versus 1.3 V @ 8 A) represent performance improvements. Mechanical compatibility is confirmed through identical TO-220-3 packaging and through-hole mounting. Verify circuit design does not depend on the original forward voltage specification.

Q: What is the difference between STTH1002CT and STTH1602CT?

A: Both devices are STMicroelectronics products with identical reverse voltage (200 V) and reverse recovery time (25-26 ns). STTH1602CT provides higher current capacity (10 A versus 8 A). STTH1002CT matches the original DSEC16-02A current rating exactly (8 A). Forward voltage specifications differ due to different test conditions. Both are ROHS3 compliant and active products.

Q: Are MUR1620CTG and BYV32-200G interchangeable?

A: Both devices are onsemi products with identical reverse voltage (200 V), current rating (8 A), and TO-220-3 packaging. MUR1620CTG provides superior forward voltage performance (975 mV @ 8 A versus 1.15 V @ 20 A for BYV32-200G). Reverse recovery time differs (35 ns for both), but MUR1620CTG exhibits lower reverse leakage (5 µA versus 50 µA). Both support extended operating temperature range (-65°C to 175°C).

Q: Does package type affect substitution compatibility?

A: All substitute parts utilize TO-220-3 through-hole packaging, identical to the DSEC16-02A. Pin configuration and mechanical dimensions are compatible. Supplier device package designations (Tube packaging) do not affect electrical or mechanical compatibility. PCB layout and thermal management considerations remain unchanged.

Q: What compliance certifications apply to substitute parts?

A: STTH1602CT, STTH1002CT, MUR1620CTG, and BYV32-200G all carry ROHS3 compliance certification. All parts are REACH Unaffected and classified under ECCN EAR99. These certifications confirm suitability for deployment in regulated markets and modern manufacturing environments.

Q: How do reverse recovery time differences affect circuit performance?

A: All substitute parts maintain fast recovery classification (≤ 500ns, > 200mA). STTH1602CT and STTH1002CT provide reverse recovery times of 25-26 ns, matching the original specification. MUR1620CTG and BYV32-200G specify 35 ns, representing acceptable variation within fast recovery parameters. Circuit switching frequency and EMI characteristics may be marginally affected; verify through application-specific testing if EMI performance is critical.

Q: Which substitute offers the best thermal performance?

A: MUR1620CTG and BYV32-200G provide extended operating temperature range (-65°C to 175°C) compared to STTH1602CT and STTH1002CT (175°C maximum). Lower reverse leakage characteristics (5 µA for MUR1620CTG and STTH1002CT versus 50 µA for DSEC16-02A and BYV32-200G) indicate reduced power dissipation in reverse bias conditions. Forward voltage performance also influences thermal behavior; MUR1620CTG exhibits the lowest forward voltage (975 mV @ 8 A).
