DSEC16-06A Equivalent & Substitute Parts

Part Overview

The DSEC16-06A is a general-purpose diode array manufactured by IXYS, featuring a 1 Pair Common Cathode configuration rated for 600 V DC reverse voltage and 10 A average rectified current per diode. This component is packaged in a Through Hole TO-220-3 case and belongs to the HiPerFRED™ series. The part is Active in product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the critical parameters that define this diode array category. Alternative sources become necessary due to inventory availability, supply chain considerations, or specific application requirements such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DSEC16-06A is determined by strict equivalence across the following parameters:

Primary Substitution Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io) (per Diode): 10 A
• Package / Case: TO-220-3
• Mounting Type: Through Hole
• Technology: Standard
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Secondary Compliance Criteria:

• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The substitute parts STTH16L06CT and STTH16L06CTY, both manufactured by STMicroelectronics, meet all primary substitution criteria. Both parts maintain identical voltage, current, configuration, and package specifications. The STTH16L06CTY variant includes automotive-grade qualification (AEC-Q101) and extended temperature range (-40°C to 175°C), while the STTH16L06CT is rated to 175°C maximum junction temperature.

Parameter Comparison

Engineering Selection Recommendations

STTH16L06CT (STMicroelectronics)

This substitute maintains full electrical and mechanical compatibility with the DSEC16-06A across all critical parameters. The part is Active in product status with RoHS3 compliance and REACH Unaffected status. The STTH16L06CT is suitable for general-purpose applications where the maximum junction temperature rating of 175°C is acceptable. This variant offers higher inventory availability (7300 pcs) compared to the main part.

STTH16L06CTY (STMicroelectronics)

This automotive-grade variant is qualified to AEC-Q101 and extends the operating temperature range to -40°C to 175°C, providing broader thermal coverage than the DSEC16-06A (-55°C to 175°C lower bound). The STTH16L06CTY is Active in product status with identical RoHS3 and REACH compliance. This variant is appropriate for automotive applications or systems requiring AEC-Q101 qualification. Inventory availability is 3200 pcs.

Both substitute parts demonstrate lower reverse leakage current (8 µA versus 60 µA) and longer reverse recovery time (55 ns versus 35 ns) compared to the main part, representing acceptable trade-offs within the Fast Recovery diode classification.

Frequently Asked Questions (FAQ)

Q: Can STTH16L06CT and STTH16L06CTY be used interchangeably with DSEC16-06A?

A: Both STMicroelectronics parts are electrically and mechanically compatible substitutes. They share identical voltage ratings (600 V), current ratings (10 A per diode), diode configuration (1 Pair Common Cathode), and TO-220-3 package specifications. Selection between them depends on application temperature requirements and automotive qualification needs.

Q: What are the key differences between STTH16L06CT and STTH16L06CTY?

A: The primary difference is operating temperature range. STTH16L06CT is rated to 175°C maximum junction temperature, while STTH16L06CTY extends to -40°C to 175°C and includes AEC-Q101 automotive qualification. Both parts are otherwise electrically identical.

Q: Are there any performance differences I should consider?

A: The DSEC16-06A exhibits faster reverse recovery time (35 ns versus 55 ns) and higher reverse leakage current (60 µA versus 8 µA) compared to both STMicroelectronics substitutes. These differences remain within the Fast Recovery diode classification and do not affect functional substitution. Forward voltage specifications are measured at different current levels (10 A for DSEC16-06A, 8 A for STTH16L06CT/CTY), making direct comparison inappropriate.

Q: Do all three parts have the same compliance certifications?

A: All three parts are RoHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. The STTH16L06CTY additionally carries AEC-Q101 automotive qualification, which is not applicable to the DSEC16-06A or STTH16L06CT.

Q: Is the TO-220-3 package identical across all three parts?

A: Yes. All three parts use Through Hole TO-220-3 packaging with identical mechanical specifications, enabling direct board-level substitution without layout modifications.

Q: Which substitute should I select for a new design?

A: Selection depends on application requirements. For general-purpose applications with standard temperature ranges, either STTH16L06CT or STTH16L06CTY is suitable. For automotive applications or systems requiring AEC-Q101 qualification, STTH16L06CTY is the appropriate choice. For extended low-temperature operation below -40°C, the DSEC16-06A remains the only option among these three parts.
