Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PR1504-T are identified based on the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 400 V minimum
• Current - Average Rectified (Io): 1.5 A minimum
• Current - Reverse Leakage @ Vr: 5 µA @ 400 V maximum
• Mounting Type: Through Hole
• RoHS3 Compliance: Required

Mechanical Compatibility Criteria:

• Package / Case: DO-204AC (DO-15) or DO-204AL (DO-41) axial packages
• Supplier Device Package: Compatible through-hole axial configurations

Substitute parts must satisfy all electrical parameters at or above the main part specifications and maintain through-hole axial mounting compatibility. Forward voltage, recovery time, and operating temperature variations are acceptable provided the substitute meets minimum electrical ratings.

Parameter Comparison

Engineering Selection Recommendations

PR1504-T (Diodes Incorporated)

The PR1504-T is the primary component specification. It delivers fast recovery characteristics with 150 ns reverse recovery time, suitable for applications requiring rapid switching performance. The part is Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Current inventory of 668 pieces supports immediate availability.

1N5395-E3/54 (Vishay General Semiconductor - Diodes Division)

The 1N5395-E3/54 is a direct electrical substitute meeting all voltage and current requirements. This part features standard recovery characteristics (2 µs trr) and is packaged in DO-204AL (DO-41) configuration. The higher forward voltage (1.4 V @ 1.5 A) compared to the PR1504-T results in increased power dissipation. Operating temperature range is -50°C to 150°C, which is narrower at the lower bound than the main part. RoHS3 compliance and unlimited MSL rating are maintained. Inventory availability is 25,278 pieces.

GP15G-E3/54 (Vishay General Semiconductor - Diodes Division)

The GP15G-E3/54 is a direct electrical substitute with identical package configuration (DO-204AC, DO-15) to the PR1504-T. This part features the lowest forward voltage (1.1 V @ 1.5 A) among the three options, resulting in reduced power dissipation. Standard recovery time is 3.5 µs. The operating temperature range extends to 175°C at the upper limit, providing enhanced thermal margin. RoHS3 compliance and unlimited MSL rating are maintained. Inventory availability is 10,959 pieces.

All three parts satisfy the core electrical and mechanical substitution criteria. Selection between substitutes depends on application-specific requirements for recovery speed, forward voltage characteristics, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the 1N5395-E3/54 be used as a direct replacement for the PR1504-T?

A: The 1N5395-E3/54 meets all electrical requirements (400 V, 1.5 A, 5 µA leakage) and is RoHS3 compliant. However, the package differs: 1N5395-E3/54 uses DO-204AL (DO-41) while PR1504-T uses DO-204AC (DO-15). Both are axial through-hole packages with different physical dimensions. PCB layout compatibility must be verified before substitution.

Q: What is the primary difference between the GP15G-E3/54 and PR1504-T?

A: Both parts use identical DO-204AC (DO-15) packaging and meet all electrical specifications. The GP15G-E3/54 has lower forward voltage (1.1 V vs. 1.2 V) and slower recovery time (3.5 µs vs. 150 ns). The GP15G-E3/54 also supports higher maximum junction temperature (175°C vs. 150°C).

Q: Why does the 1N5395-E3/54 have higher forward voltage than the PR1504-T?

A: Forward voltage variation is a normal characteristic difference between different diode designs and manufacturing processes. The 1N5395-E3/54 specification of 1.4 V @ 1.5 A is within acceptable limits for general-purpose rectifier applications. Circuit designers must account for this difference in power dissipation calculations.

Q: Are all three parts suitable for high-speed switching applications?

A: The PR1504-T with 150 ns reverse recovery time is optimized for fast switching. The 1N5395-E3/54 (2 µs) and GP15G-E3/54 (3.5 µs) have standard recovery characteristics. Application requirements for switching speed determine which part is appropriate.

Q: Do all substitute parts maintain the same operating temperature range?

A: No. The PR1504-T operates from -65°C to 150°C. The 1N5395-E3/54 operates from -50°C to 150°C (narrower lower bound). The GP15G-E3/54 operates from -65°C to 175°C (extended upper bound). Application temperature requirements must be verified against each part's specifications.

Q: Are all parts RoHS3 compliant?

A: Yes. The PR1504-T, 1N5395-E3/54, and GP15G-E3/54 are all RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).
