Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP75AE3/TR13 are classified based on electrical parameter equivalence and mechanical compatibility. The primary substitution criteria are:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 75V
• Voltage - Clamping (Max) @ Ipp: 121V (±1V tolerance acceptable)
• Current - Peak Pulse (10/1000µs): 41.3A (±5% tolerance acceptable)
• Power - Peak Pulse: 5000W (5kW)
• Operating Temperature Range: -55°C to 175°C
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Type: Zener, Unidirectional (1 channel)

Direct Equivalents maintain all critical electrical parameters and identical package specifications. These parts are interchangeable without circuit redesign.

Similar Equivalents maintain voltage and temperature specifications but may differ in peak pulse current or power ratings. These parts require application-level verification to confirm suitability for specific transient energy levels.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Interchangeable without circuit modification):

The 5KP75A-E3/54 (Vishay General Semiconductor - Diodes Division) is a direct electrical and mechanical equivalent. This part maintains identical voltage specifications (75V standoff, 121V clamping), peak pulse current (41.3A), and power rating (5000W). Both parts utilize the P600 axial package and operate across the same temperature range (-55°C to 175°C). The Vishay part is ROHS3 compliant with unlimited MSL rating. The primary difference is packaging format (Cut Tape versus Tape & Reel), which does not affect electrical performance or board-level compatibility.

The 5KP75A (Littelfuse Inc.) is functionally equivalent with negligible parameter variance. Peak pulse current specification is 42.1A, representing a 1.9% increase from the 41.3A baseline. All other electrical parameters, temperature range, and package specifications are identical. This part is ROHS3 compliant and available in Cut Tape format.

Similar Equivalents (Application-level verification required):

The 15KPA75A (MDE Semiconductor Inc) maintains voltage specifications within acceptable tolerance (75V standoff, 122V clamping) and temperature range compatibility. However, this part features significantly higher peak pulse current (123.8A) and power dissipation capability (15000W versus 5000W). This part is suitable for applications requiring enhanced transient energy absorption but should be selected only when the higher performance envelope is required or beneficial. The 15KPA75A is ROHS3 compliant and available in Bulk packaging.

The 5KP75A-TP (Micro Commercial Co) maintains voltage and power specifications but uses an R-6 axial package variant instead of the standard P600. Peak pulse current specification is not provided in available documentation. This part is ROHS3 compliant and available in Cut Tape format. Package compatibility must be verified for specific board layouts.

Compliance Status:

All identified substitute parts maintain ROHS3 compliance and unlimited MSL rating (Level 1), ensuring compatibility with standard manufacturing and storage environments. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Frequently Asked Questions (FAQ)

Q: Can the 5KP75A-E3/54 (Vishay) be used as a direct replacement for the 5KP75AE3/TR13 (Microchip)?

A: Yes. The 5KP75A-E3/54 is a direct electrical equivalent with identical voltage specifications (75V standoff, 121V clamping), peak pulse current (41.3A), power rating (5000W), and operating temperature range (-55°C to 175°C). Both parts use the P600 axial through-hole package. The only difference is packaging format (Cut Tape versus Tape & Reel), which does not affect circuit performance or board-level installation.

Q: What is the difference between the 5KP75A (Littelfuse) and the 5KP75AE3/TR13 (Microchip)?

A: The 5KP75A differs only in peak pulse current specification (42.1A versus 41.3A), representing a 1.9% increase. All other parameters—voltage ratings, power dissipation, temperature range, and package type—are identical. This minor variance is within typical engineering tolerance and does not affect circuit functionality.

Q: When should the 15KPA75A (MDE) be selected instead of the 5KP75AE3/TR13?

A: The 15KPA75A should be selected when the application requires higher transient energy absorption capability. This part provides 123.8A peak pulse current and 15000W power dissipation, compared to 41.3A and 5000W for the 5KP75AE3/TR13. Selection depends on the specific transient voltage event magnitude and duration in the target application. Both parts maintain identical voltage specifications and temperature range.

Q: Is the 5KP75A-TP (Micro Commercial Co) compatible with the 5KP75AE3/TR13?

A: The 5KP75A-TP maintains identical voltage and power specifications but uses an R-6 axial package instead of the standard P600 package. Physical dimensions and lead spacing may differ. Compatibility depends on specific board layout and footprint requirements. Peak pulse current specification is not documented for this variant. Mechanical fit verification is required before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts—5KP75A-E3/54 (Vishay), 5KP75A (Littelfuse), 5KP75A-TP (Micro Commercial Co), and 15KPA75A (MDE)—are ROHS3 compliant with unlimited MSL rating (Level 1). All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: What packaging formats are available for these TVS diodes?

A: The 5KP75AE3/TR13 is supplied in Tape & Reel (TR) format. Substitute parts are available in multiple formats: Cut Tape (CT) for 5KP75A-E3/54, 5KP75A, and 5KP75A-TP; and Bulk for 15KPA75A. Packaging format selection depends on manufacturing process requirements and volume needs but does not affect electrical performance.

Q: What is the operating temperature range for all these parts?

A: All identified parts operate across the same temperature range: -55°C to 175°C (junction temperature). This specification is consistent across all manufacturers and variants.
