DSS16-01A Equivalent & Substitute Parts

Part Overview

The DSS16-01A is an IXYS Schottky rectifier diode rated for 100 V DC reverse voltage and 16 A average rectified current in a through-hole TO-220AC package. This component is designed for high-speed switching applications requiring fast recovery characteristics (≤500 ns). The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, application-specific requirements, or design optimization needs.

Substitute Part Grouping Explanation

Substitution of the DSS16-01A is permissible when the alternative component meets or exceeds the following critical electrical and mechanical parameters:

Mandatory Compatibility Criteria:

• Technology: Schottky rectifier diode
• Package / Case: TO-220-2 (through-hole mounting)
• Voltage - DC Reverse (Vr) (Max): Equal to or greater than 100 V
• Current - Average Rectified (Io): Equal to or greater than 16 A
• Speed: Fast Recovery ≤500 ns, >200 mA (Io)
• Operating Temperature - Junction: Minimum -55°C to maximum 175°C or higher
• RoHS Status: ROHS3 Compliant

The STPS20120D from STMicroelectronics satisfies all mandatory criteria with enhanced voltage and current ratings, making it a valid substitute for the DSS16-01A in applications where the original part is unavailable or where higher performance margins are required.

Engineering Selection Recommendations

DSS16-01A (IXYS): Select this part when the original design specification calls for 100 V / 16 A performance and inventory availability permits. The component is active in production with full RoHS3 compliance and REACH unaffected status. Current stock of 1650 units supports immediate procurement.

STPS20120D (STMicroelectronics): This substitute is suitable for applications where the DSS16-01A is unavailable or where enhanced voltage and current ratings provide design margin. The STPS20120D delivers 120 V / 20 A performance in the identical TO-220AC package with equivalent fast recovery characteristics. Both components maintain ROHS3 compliance and REACH unaffected status. The substitute exhibits lower reverse leakage current (20 µA vs. 500 µA at rated voltage), which may improve circuit efficiency in low-current standby conditions. Current stock of 1240 units is available.

Both parts are suitable for direct substitution in through-hole PCB applications without mechanical modification. Forward voltage characteristics differ at rated current levels; thermal design calculations should account for the higher forward voltage of the STPS20120D in high-current continuous operation.

Frequently Asked Questions (FAQ)

Q: Can the STPS20120D replace the DSS16-01A in all applications?

A: The STPS20120D is electrically compatible with the DSS16-01A for applications operating at or below 100 V and 16 A. The substitute's higher voltage and current ratings (120 V / 20 A) do not create incompatibility. Both components share identical TO-220AC packaging and fast recovery characteristics. Thermal performance may differ due to higher forward voltage; verify thermal design margins in high-current applications.

Q: What are the key differences between these two parts?

A: The primary differences are voltage rating (100 V vs. 120 V), current rating (16 A vs. 20 A), forward voltage drop (790 mV vs. 930 mV at rated current), and reverse leakage current (500 µA vs. 20 µA). Both parts employ Schottky technology with identical fast recovery speed and operating temperature range. The STPS20120D provides higher performance margins and lower leakage characteristics.

Q: Are there any package or mounting differences?

A: Both the DSS16-01A and STPS20120D use the TO-220-2 package with through-hole mounting. No PCB layout modifications or mechanical changes are required for substitution. Pin configuration and thermal pad alignment are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the DSS16-01A and STPS20120D are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. Moisture sensitivity level is 1 (unlimited) for both components, indicating no special storage or handling requirements.

Q: How does forward voltage affect circuit performance?

A: Forward voltage drop directly impacts power dissipation and thermal generation. The STPS20120D exhibits 140 mV higher forward voltage at its rated current (930 mV vs. 790 mV). In applications with continuous high current, this difference increases heat generation. Calculate power dissipation (P = Vf × I) for your specific operating current to determine thermal impact. At lower currents, the difference is proportionally reduced.

Q: Can I use the STPS20120D in a 100 V circuit designed for the DSS16-01A?

A: Yes. The STPS20120D is rated for 120 V reverse voltage, which exceeds the 100 V circuit requirement. The component operates safely at 100 V with additional voltage margin. This substitution is valid for all circuit topologies and operating conditions within the original 100 V / 16 A specification.
