PDR5K-13 Equivalent & Substitute Parts

Part Overview

The PDR5K-13 is a general-purpose rectifier diode manufactured by Diodes Incorporated, rated for 750 V DC reverse voltage and 5 A average rectified current in a PowerDI™ 5 surface mount package. This part is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PDR5K-13 is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - DC Reverse (Vr) rating must equal or exceed 750 V
• Current - Average Rectified (Io) must equal or exceed 5 A
• Voltage - Forward (Vf) must not exceed 990 mV @ 5 A
• Reverse Recovery Time (trr) must not exceed 3 µs
• Current - Reverse Leakage must not exceed 10 µA @ rated voltage

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package / Case: PowerDI™ 5

Compliance Requirements:

• RoHS3 Compliant status required
• Active product status preferred for ongoing availability

The substitute parts S5KP5-13 and S5KP5M-13 meet these criteria with enhanced voltage ratings (800 V) and active product status, providing superior performance margins and manufacturing continuity.

Parameter Comparison

Engineering Selection Recommendations

S5KP5-13 Selection Criteria: The S5KP5-13 is an active product offering 800 V reverse voltage rating with identical forward voltage and recovery time characteristics. This part provides a direct functional upgrade with enhanced voltage margin. ROHS3 compliance and active manufacturing status support long-term supply chain continuity. Selection is appropriate for applications where bulk packaging is acceptable.

S5KP5M-13 Selection Criteria: The S5KP5M-13 is functionally equivalent to S5KP5-13 with the addition of Tape & Reel packaging, AEC-Q101 automotive qualification, and automotive-grade designation. This part is suitable for high-volume production environments and applications requiring automotive-grade components. Active product status and ROHS3 compliance ensure manufacturing availability and regulatory compliance.

Substitution Feasibility: Both substitute parts satisfy all critical electrical parameters of the PDR5K-13. The 800 V rating provides a 50 V margin above the original 750 V specification. Forward voltage, recovery time, and leakage current remain identical or superior. PowerDI™ 5 package compatibility ensures mechanical interchangeability without PCB redesign.

The primary trade-off involves operating temperature range: substitute parts operate to 150°C maximum junction temperature compared to 155°C for the original part. This 5°C reduction is acceptable for most applications operating within standard industrial temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can S5KP5-13 or S5KP5M-13 directly replace PDR5K-13 without circuit modification?

A: Yes. Both substitute parts maintain identical electrical performance in the critical parameters: 5 A current rating, 990 mV forward voltage at 5 A, and 3 µs recovery time. The 800 V reverse voltage rating exceeds the original 750 V specification, providing additional safety margin. PowerDI™ 5 package dimensions are identical, requiring no PCB layout changes.

Q: What is the difference between S5KP5-13 and S5KP5M-13?

A: S5KP5-13 is supplied in bulk packaging, while S5KP5M-13 is supplied in Tape & Reel format. S5KP5M-13 includes AEC-Q101 automotive qualification and automotive-grade designation. Both parts are electrically identical. Selection depends on packaging requirements and whether automotive-grade certification is necessary for the application.

Q: Why do the substitute parts have a higher voltage rating (800 V vs. 750 V)?

A: The S5KP5 series represents the current active product line from Diodes Incorporated for this performance class. The 800 V rating provides improved voltage margin and is standard for modern rectifier designs. This enhancement does not affect circuit compatibility and improves reliability in applications with voltage transients or marginal supply conditions.

Q: Are there any temperature range limitations when substituting?

A: The substitute parts operate to -55°C to 150°C junction temperature, compared to -65°C to 155°C for the original PDR5K-13. The lower minimum temperature (-55°C vs. -65°C) and maximum temperature (-150°C vs. 155°C) represent minor restrictions. For applications operating within standard industrial temperature ranges (-40°C to 125°C), this difference is not significant.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both S5KP5-13 and S5KP5M-13 are ROHS3 compliant, matching the original part. S5KP5M-13 additionally carries AEC-Q101 automotive qualification. Both parts carry EAR99 ECCN classification and HTSUS code 8541.10.0080, identical to the original part.

Q: Which substitute part should be selected for new production designs?

A: S5KP5M-13 is recommended for new production designs due to active product status, Tape & Reel packaging suitable for automated assembly, and AEC-Q101 qualification providing additional quality assurance. S5KP5-13 is suitable if bulk packaging is preferred or automotive qualification is not required.
