DSP25-16AR Equivalent & Substitute Parts

Part Overview

The DSP25-16AR is a diode array rectifier manufactured by IXYS, configured as a 1 Pair Series Connection rated for 1600 V DC reverse voltage with 28 A average rectified current per diode. This component is packaged in a TO-247-3 through-hole configuration and is designed for general-purpose rectification applications requiring high voltage and moderate current handling. The part maintains Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when inventory constraints require component alternatives that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DSP25-16AR are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Voltage - DC Reverse (Vr) (Max): 1600 V
• Current - Average Rectified (Io) (per Diode): 28 A
• Voltage - Forward (Vf) (Max) @ If: 1.6 V @ 55 A
• Current - Reverse Leakage @ Vr: 2 mA @ 1600 V
• Operating Temperature - Junction: -40°C to 180°C
• Diode Configuration: 1 Pair Series Connection
• Technology: Standard
• Speed: Standard Recovery >500ns, > 200mA (Io)
• Package / Case: TO-247-3
• Mounting Type: Through Hole

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. The DSP25-16A qualifies as a substitute part under this framework, differing only in the supplier device package designation (TO-247AD versus ISOPLUS247™) while maintaining identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the DSP25-16AR and DSP25-16A are Active products manufactured by IXYS with identical electrical specifications and mechanical compatibility. Selection between these parts is based on availability and sourcing requirements rather than technical performance differences.

The DSP25-16AR features the ISOPLUS247™ supplier device package designation and maintains 2163 pieces in current inventory stock. The DSP25-16A features the TO-247AD supplier device package designation and maintains 1619 pieces in current inventory stock. Both parts carry ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications.

The TO-247-3 through-hole mounting configuration is identical between both parts, ensuring mechanical interchangeability in PCB layouts and thermal management designs. Forward voltage characteristics, reverse leakage specifications, and operating temperature ranges are equivalent, confirming functional equivalence for circuit design purposes.

Frequently Asked Questions (FAQ)

Q: Can DSP25-16A be used as a direct replacement for DSP25-16AR in existing designs?

A: Yes. The DSP25-16A is a parametric equivalent with identical electrical specifications and mechanical compatibility. Both parts feature the TO-247-3 package, 1600 V reverse voltage rating, 28 A average rectified current, and equivalent forward voltage and reverse leakage characteristics. The difference in supplier device package designation (TO-247AD versus ISOPLUS247™) does not affect functional performance or PCB mounting.

Q: What are the critical parameters that define substitution eligibility for DSP25-16AR?

A: Substitution eligibility is determined by matching all of the following parameters: 1600 V DC reverse voltage rating, 28 A average rectified current per diode, 1.6 V forward voltage at 55 A, 2 mA reverse leakage at 1600 V, -40°C to 180°C operating temperature range, 1 Pair Series Connection configuration, Standard technology, Standard recovery speed >500ns, TO-247-3 package, and through-hole mounting type. Any deviation from these specifications disqualifies a part from substitution.

Q: Are there differences in thermal performance between DSP25-16AR and DSP25-16A?

A: No thermal performance differences exist between these parts. Both components share identical operating temperature ranges (-40°C to 180°C junction temperature) and equivalent electrical characteristics that determine thermal behavior in circuit applications.

Q: What is the significance of the supplier device package designation difference?

A: The supplier device package designation (ISOPLUS247™ for DSP25-16AR and TO-247AD for DSP25-16A) represents different naming conventions for mechanically and electrically equivalent TO-247-3 packages. This designation difference does not affect pin configuration, thermal characteristics, or electrical performance.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both DSP25-16AR and DSP25-16A are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What inventory considerations should guide part selection?

A: DSP25-16AR maintains 2163 pieces in stock, while DSP25-16A maintains 1619 pieces in stock. Selection should be based on immediate availability requirements and project lead time constraints, as both parts are functionally equivalent.
