Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP85AE3/TR13 are classified into two categories based on electrical parameter compatibility:

Direct Equivalents maintain identical electrical specifications across all critical parameters: 85V reverse standoff voltage, 137V clamping voltage, 36.5A peak pulse current, and 5000W peak pulse power. These parts are functionally interchangeable with the main part number.

Similar Alternatives share the same voltage class (85V standoff, 137V+ clamping) and Through Hole P600 axial package but differ in peak pulse current and power dissipation ratings. These parts provide enhanced performance capability in the same physical form factor.

Substitution eligibility is determined by the following parameters:

• Voltage - Reverse Standoff (Typ): 85V
• Voltage - Clamping (Max) @ Ipp: 137V or greater
• Package / Case: P600, Axial
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C to 175°C or broader
• Type: Zener, Unidirectional

Engineering Selection Recommendations

5KP85A-E3/54 (Vishay General Semiconductor - Direct Equivalent)

The 5KP85A-E3/54 is a direct electrical and mechanical equivalent to the 5KP85AE3/TR13. Both parts maintain identical voltage specifications (85V standoff, 137V clamping), peak pulse current (36.5A), and power dissipation (5000W). The primary difference is packaging format: the main part is supplied in Tape & Reel configuration while the substitute is supplied in Cut Tape. Both are ROHS3 compliant with MSL 1 rating and Active product status. This part is suitable for direct substitution where packaging format is not a constraint.

15KPA85A (MDE Semiconductor Inc - Enhanced Performance Alternative)

The 15KPA85A provides enhanced transient suppression capability with 109.7A peak pulse current and 15000W peak pulse power, compared to 36.5A and 5000W in the main part. Voltage specifications remain compatible (85V standoff, 137.6V clamping). The P600 axial Through Hole package and operating temperature range (-55 to 175°C) are identical. This part is suitable for applications requiring higher transient energy absorption while maintaining the same physical footprint and voltage class. ROHS3 compliance and MSL 1 rating are maintained.

5KP85A (Diotec Semiconductor - Equivalent Performance Alternative)

The 5KP85A from Diotec Semiconductor matches the main part across voltage specifications (85V standoff, 137V clamping) and power rating (5000W). Peak pulse current is specified as 36A, which is within the tolerance band of the main part's 36.5A specification. The P600 axial Through Hole package is identical. Operating temperature range extends to -50°C minimum (compared to -55°C), providing a slightly narrower low-temperature specification. ROHS3 compliance is maintained. This part is suitable for direct substitution in applications where the -50°C minimum temperature is acceptable.

All substitute parts maintain Active product status and ROHS3 compliance, confirming ongoing manufacturer support and environmental regulatory conformance.

Frequently Asked Questions (FAQ)

Q: Can the 5KP85A-E3/54 be used as a direct replacement for the 5KP85AE3/TR13?

A: Yes. Both parts are electrically identical with 85V reverse standoff voltage, 137V clamping voltage, 36.5A peak pulse current, and 5000W peak pulse power. The difference is packaging format: Tape & Reel versus Cut Tape. If the application accommodates Cut Tape packaging, this part provides direct functional replacement.

Q: What is the difference between the 15KPA85A and the main part?

A: The 15KPA85A provides higher transient energy handling with 109.7A peak pulse current and 15000W peak pulse power, compared to 36.5A and 5000W in the 5KP85AE3/TR13. Voltage specifications (85V standoff, 137.6V clamping) remain compatible. The physical package (P600 axial) is identical. This part is suitable for applications requiring enhanced overvoltage suppression capability.

Q: Are all substitute parts compatible with the same circuit board layout?

A: Yes. All substitute parts use the P600 axial Through Hole package with identical mechanical dimensions. Board layout and mounting hole spacing remain unchanged across all listed parts.

Q: What is the operating temperature difference between the 5KP85A and the main part?

A: The 5KP85A from Diotec Semiconductor specifies a minimum operating temperature of -50°C, compared to -55°C for the main part. The maximum temperature (175°C) is identical. Applications requiring operation below -50°C must use the main part or the 5KP85A-E3/54 substitute.

Q: Do all substitute parts meet the same compliance standards?

A: All listed substitute parts are ROHS3 compliant and maintain Active product status. The main part and direct equivalent (5KP85A-E3/54) both carry MSL 1 (Unlimited) moisture sensitivity rating. The 15KPA85A also carries MSL 1 rating. The 5KP85A from Diotec lists MSL as Not Applicable. All parts carry EAR99 ECCN classification.

Q: Which substitute part should be selected for maximum design margin?

A: The 15KPA85A provides the highest transient energy absorption capability with 15000W peak pulse power and 109.7A peak pulse current. This part is suitable for applications where enhanced protection margin is required while maintaining the same voltage class and physical package.

Q: Can packaging format affect part selection?

A: Yes. The main part is supplied in Tape & Reel format suitable for automated assembly. The 5KP85A-E3/54 is supplied in Cut Tape format. The 15KPA85A is supplied in Bulk format. Selection depends on assembly process requirements and inventory management practices.
