Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP26AE3/TR13 is determined by electrical parameter compatibility and mechanical form factor alignment. The critical parameters governing substitution are:

Electrical Parameters:

• Voltage - Reverse Standoff (Typ): 26V
• Voltage - Breakdown (Min): 28.9V
• Voltage - Clamping (Max) @ Ipp: 42.1V
• Current - Peak Pulse (10/1000µs): 119A minimum
• Power - Peak Pulse: 5000W (5kW)

Mechanical Parameters:

• Mounting Type: Through Hole
• Package / Case: P600, Axial

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Operating Temperature: -55°C to 175°C (TJ)

Parts are classified as direct equivalents when all electrical parameters match exactly and the package form factor is identical. Parts are classified as similar alternatives when electrical parameters remain within acceptable tolerance ranges for the application category (General Purpose TVS protection) but may differ in peak pulse current or packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

5KP26A-E3/54 (Vishay General Semiconductor - Direct Equivalent)

The 5KP26A-E3/54 is a direct electrical and mechanical equivalent to the 5KP26AE3/TR13. Both parts share identical voltage ratings (26V standoff, 28.9V breakdown minimum, 42.1V clamping maximum), peak pulse current (119A), and power dissipation (5kW). Both are housed in P600 axial through-hole packages with identical operating temperature ranges (-55°C to 175°C). The primary difference is packaging format: the main part is supplied in Tape & Reel configuration while the substitute is supplied in Cut Tape format. Both maintain ROHS3 compliance and unlimited moisture sensitivity rating. This part is suitable for direct substitution in applications where packaging format flexibility is acceptable.

5KP26A (Littelfuse Inc. - Similar Alternative)

The 5KP26A maintains electrical compatibility with the main part across all critical voltage parameters (26V standoff, 28.9V breakdown, 42.1V clamping) and power rating (5kW). Peak pulse current is marginally higher at 121.1A compared to 119A, providing equivalent or superior transient protection capability. The package form factor (P600 axial) and operating temperature range (-55°C to 175°C) are identical. This part is suitable for substitution in applications where the slightly elevated peak pulse current specification does not create design constraints.

LCE28A (Littelfuse Inc. - Limited Compatibility)

The LCE28A differs from the main part in multiple electrical parameters: reverse standoff voltage is 28V (versus 26V), breakdown voltage is 31.1V (versus 28.9V), and clamping voltage is 45.5V (versus 42.1V). Peak pulse current is significantly lower at 33A compared to 119A, and power dissipation is reduced to 1500W versus 5000W. The package form factor is DO-201AA (versus P600), requiring different board layout accommodation. This part is suitable only for applications with lower transient current requirements and higher voltage tolerance margins. Direct substitution in circuits designed for the 5KP26AE3/TR13 is not recommended without circuit re-evaluation.

All substitute parts maintain active product status, ROHS3 compliance, and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the 5KP26A-E3/54 be used as a direct replacement for the 5KP26AE3/TR13?

A: Yes. The 5KP26A-E3/54 is a direct electrical and mechanical equivalent. Both parts have identical voltage ratings (26V standoff, 28.9V breakdown, 42.1V clamping), peak pulse current (119A), power dissipation (5kW), and P600 axial package form factor. The only difference is the packaging format (Cut Tape versus Tape & Reel), which does not affect circuit performance.

Q: What is the difference between the 5KP26A and the main part 5KP26AE3/TR13?

A: The 5KP26A has identical voltage ratings and package form factor but features a slightly higher peak pulse current specification (121.1A versus 119A). This represents a marginal improvement in transient current handling capability. All other electrical and mechanical parameters are equivalent. The part is suitable for direct substitution.

Q: Why is the LCE28A listed as a substitute if it has different voltage ratings?

A: The LCE28A is listed as a similar alternative rather than a direct equivalent. It maintains the same zener diode type, unidirectional channel configuration, through-hole mounting, and operating temperature range. However, the higher voltage ratings (28V standoff, 31.1V breakdown, 45.5V clamping) and significantly lower peak pulse current (33A versus 119A) and power rating (1500W versus 5000W) make it suitable only for applications with different transient protection requirements. Direct substitution in circuits designed for the 5KP26AE3/TR13 requires circuit re-evaluation.

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

A: The 5KP26AE3/TR13 is supplied in Tape & Reel (TR) format for automated assembly. The 5KP26A-E3/54 and 5KP26A are supplied in Cut Tape (CT) format for manual or semi-automated assembly. The LCE28A is also supplied in Cut Tape format. All parts are through-hole mounted components with axial lead configuration.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The main part 5KP26AE3/TR13 and all listed substitute parts (5KP26A-E3/54, 5KP26A, and LCE28A) are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), ensuring regulatory compliance and environmental compatibility.

Q: What is the operating temperature range for these TVS diodes?

A: All listed parts operate across the temperature range of -55°C to 175°C (junction temperature). This range is identical across the main part and all direct and similar substitute parts, ensuring thermal compatibility in circuit applications.

Q: Can the LCE28A be used in a circuit designed for the 5KP26AE3/TR13?

A: The LCE28A has different electrical specifications and package form factor (DO-201AA versus P600). While it maintains the same zener diode type and operating temperature range, the higher voltage ratings and significantly lower peak pulse current and power dissipation make it unsuitable for direct substitution without circuit re-evaluation and potential redesign.
