PDS540Q-13 Equivalent & Substitute Parts

Part Overview

The PDS540Q-13 is a Schottky rectifier diode manufactured by Diodes Incorporated, rated for 40 V DC reverse voltage and 5 A average rectified current in a PowerDI™ 5 surface mount package. The device is qualified to AEC-Q101 automotive standards and is actively produced. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when packaging configurations differ for specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PDS540Q-13 are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io): 5 A
• Voltage - Forward (Vf) (Max) @ If: 520 mV @ 5 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 250 µA @ 40 V
• Technology: Schottky

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Operating Temperature - Junction: -65°C ~ 150°C (or higher minimum)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitutes are grouped into two categories: parametric equivalents with different packaging configurations and manufacturer-recommended alternatives with different package types.

Parameter Comparison

Engineering Selection Recommendations

PDS540-13 (Diodes Incorporated): This part is a parametric equivalent to the PDS540Q-13, sharing identical electrical specifications and the same PowerDI™ 5 package footprint. The primary difference is the packaging configuration: PDS540-13 is supplied in Cut Tape (CT) and Digi-Reel® format, whereas PDS540Q-13 is supplied in Tape & Reel (TR). Both parts are manufactured by Diodes Incorporated, maintain ROHS3 compliance, and are actively produced. Selection between these two depends on procurement and assembly line requirements for packaging format.

SV540_R2_00001 (Panjit International Inc.): This part meets all electrical specifications of the PDS540Q-13 and is manufacturer-recommended as a substitute. The device uses a TO-277 (3-PowerDFN) package instead of PowerDI™ 5, requiring PCB layout and footprint modifications. The operating temperature range is -55°C ~ 150°C, which is narrower at the lower end compared to the PDS540Q-13 (-65°C ~ 150°C). This part is ROHS3 compliant and actively produced. Selection of this substitute is appropriate when package size or thermal characteristics of the TO-277 format provide design advantages, provided the -55°C minimum junction temperature meets application requirements.

All substitute parts maintain AEC-Q101 or equivalent automotive qualification status and ROHS3 compliance, ensuring suitability for automotive and industrial applications.

Frequently Asked Questions (FAQ)

Q: Can PDS540-13 be used as a direct replacement for PDS540Q-13?

A: Yes. Both parts are manufactured by Diodes Incorporated and share identical electrical parameters, technology (Schottky), and package type (PowerDI™ 5). The only difference is the packaging configuration: PDS540-13 uses Cut Tape (CT) and Digi-Reel® format, while PDS540Q-13 uses Tape & Reel (TR). Electrical and mechanical compatibility is complete. Selection depends on procurement and assembly requirements.

Q: What are the key differences between PDS540Q-13 and SV540_R2_00001?

A: Both parts meet identical electrical specifications (40 V, 5 A, 520 mV forward voltage, fast recovery). The primary differences are: (1) Manufacturer: Diodes Incorporated versus Panjit International Inc.; (2) Package type: PowerDI™ 5 versus TO-277 (3-PowerDFN), requiring different PCB footprints; (3) Operating temperature range: -65°C ~ 150°C versus -55°C ~ 150°C. PCB layout modification is required when switching to SV540_R2_00001.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. PDS540-13 and SV540_R2_00001 are both ROHS3 compliant, matching the compliance status of the PDS540Q-13. All parts also maintain Moisture Sensitivity Level (MSL) 1 (Unlimited) rating.

Q: What is the impact of the different package types on circuit design?

A: PDS540Q-13 and PDS540-13 use the same PowerDI™ 5 package footprint and are interchangeable without PCB modification. SV540_R2_00001 uses a TO-277 (3-PowerDFN) package, which has a different footprint and pin configuration. Switching to SV540_R2_00001 requires PCB layout redesign and re-qualification of thermal and electrical performance in the new package.

Q: Can SV540_R2_00001 be used in applications requiring -65°C operation?

A: No. SV540_R2_00001 has a minimum operating junction temperature of -55°C, whereas PDS540Q-13 operates down to -65°C. Applications requiring -65°C operation must use PDS540Q-13 or PDS540-13.

Q: Are there inventory differences between the substitute parts?

A: Yes. PDS540Q-13 has 16,084 pieces in stock, PDS540-13 has 39,200 pieces in stock, and SV540_R2_00001 has 4,074 pieces in stock. Availability may influence selection when lead time is a consideration.
