PR1502-T Equivalent & Substitute Parts

Part Overview

The PR1502-T is a general-purpose rectifier diode manufactured by Diodes Incorporated, rated for 100 V DC reverse voltage and 1.5 A average rectified current in a DO-15 through-hole axial package. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical ratings and mechanical compatibility allow direct replacement in circuit applications while maintaining performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PR1502-T are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 100 V minimum
• Current - Average Rectified (Io): 1.5 A minimum
• Current - Reverse Leakage @ Vr: 5 µA @ 100 V maximum
• Mounting Type: Through Hole
• RoHS3 Compliance: Required

Mechanical Compatibility Criteria:

• Package / Case: DO-204AC (DO-15) or DO-204AL (DO-41) axial configurations
• Lead configuration: Axial through-hole

The substitute parts listed below meet or exceed these criteria and are therefore electrically and mechanically compatible with the PR1502-T in general-purpose rectification applications.

Engineering Selection Recommendations

GP15B-E3/54 (Vishay General Semiconductor - Diodes Division)

The GP15B-E3/54 is a direct mechanical and electrical substitute for the PR1502-T. Both components share identical voltage and current ratings (100 V, 1.5 A) and are packaged in DO-204AC (DO-15) axial configuration. The GP15B-E3/54 features a lower forward voltage drop (1.1 V versus 1.2 V) and an extended operating temperature range (-65°C to 175°C versus -65°C to 150°C). Both parts are RoHS3 compliant and carry Active product status. The GP15B-E3/54 is part of the SUPERECTIFIER® series and is available in higher inventory quantities (9002 pcs).

1N5392-E3/54 (Vishay General Semiconductor - Diodes Division)

The 1N5392-E3/54 is an electrical substitute with identical voltage and current ratings (100 V, 1.5 A) and equivalent reverse leakage characteristics (5 µA @ 100 V). This component is packaged in DO-204AL (DO-41) axial configuration, which differs mechanically from the PR1502-T DO-15 package. The 1N5392-E3/54 exhibits a higher forward voltage drop (1.4 V versus 1.2 V) and operates within the temperature range of -50°C to 150°C. Both parts are RoHS3 compliant and carry Active product status. Package substitution from DO-15 to DO-41 requires physical board layout verification.

Frequently Asked Questions (FAQ)

Q: Can the GP15B-E3/54 replace the PR1502-T without circuit modification?

A: Yes. The GP15B-E3/54 is electrically and mechanically equivalent to the PR1502-T. Both components are rated for 100 V reverse voltage and 1.5 A average rectified current and are packaged in identical DO-204AC (DO-15) axial configuration. No circuit modifications are required.

Q: What is the difference between the DO-15 and DO-41 packages?

A: DO-15 (DO-204AC) and DO-41 (DO-204AL) are both axial through-hole packages with different physical dimensions. The DO-15 package is more compact than the DO-41 package. The 1N5392-E3/54 uses DO-41 packaging, while the PR1502-T and GP15B-E3/54 use DO-15 packaging. Physical board layout must accommodate the larger DO-41 footprint if substituting with the 1N5392-E3/54.

Q: How do forward voltage drop differences affect circuit performance?

A: The PR1502-T has a maximum forward voltage drop of 1.2 V @ 1.5 A. The GP15B-E3/54 has 1.1 V @ 1.5 A, and the 1N5392-E3/54 has 1.4 V @ 1.5 A. Lower forward voltage drop results in reduced power dissipation and heat generation. Higher forward voltage drop increases power dissipation. Circuit design must account for these differences in power supply regulation and thermal management.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The PR1502-T, GP15B-E3/54, and 1N5392-E3/54 are all RoHS3 compliant and carry REACH Unaffected status.

Q: What is the significance of reverse recovery time differences?

A: The PR1502-T has a reverse recovery time (trr) of 150 ns, classified as fast recovery. The GP15B-E3/54 has 3.5 µs, and the 1N5392-E3/54 has 2 µs, both classified as standard recovery. Reverse recovery time affects switching speed and high-frequency performance. Applications requiring fast switching characteristics should account for these differences.

Q: Can the 1N5392-E3/54 be used in place of the PR1502-T?

A: The 1N5392-E3/54 is electrically equivalent but mechanically different. It is packaged in DO-41 (DO-204AL) instead of DO-15 (DO-204AC). Physical board layout compatibility must be verified before substitution. The higher forward voltage drop (1.4 V versus 1.2 V) and longer reverse recovery time (2 µs versus 150 ns) must be evaluated for the specific application.

Q: What is the operating temperature range difference between these parts?

A: The PR1502-T operates from -65°C to 150°C. The GP15B-E3/54 operates from -65°C to 175°C, providing a 25°C higher maximum junction temperature. The 1N5392-E3/54 operates from -50°C to 150°C, with a 15°C higher minimum junction temperature. Application thermal requirements determine which part is suitable.
