5KP90AE3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP90AE3/TR13 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose transient voltage protection applications. This through-hole component operates with a 90V reverse standoff voltage and provides 146V maximum clamping voltage at peak pulse current. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified to address inventory availability, supply chain continuity, and application-specific performance requirements while maintaining electrical and mechanical compatibility within the TVS diode category.

Substitute Part Grouping Explanation

Substitute parts for the 5KP90AE3/TR13 are classified into two categories based on electrical parameter alignment:

Direct Equivalents maintain identical electrical specifications across all critical parameters: 90V reverse standoff voltage, 100V minimum breakdown voltage, 146V maximum clamping voltage, and 5000W peak pulse power rating. These parts are interchangeable in applications where the original specification must be preserved exactly.

Similar Alternatives share the core voltage protection characteristics (90V standoff, 100V breakdown, 146V clamping) but differ in peak pulse current capacity and/or power dissipation rating. These parts are suitable for applications where higher power handling or current capacity provides additional design margin, or where lower current ratings are acceptable for reduced transient stress conditions.

Substitution eligibility is determined by the following parameters:

Voltage - Reverse Standoff (Typ): 90V
Voltage - Breakdown (Min): 100V
Voltage - Clamping (Max) @ Ipp: 146V (±1V tolerance acceptable)
Mounting Type: Through Hole
Package Category: Axial (P600 or R-6 compatible footprints)
Type: Zener, Unidirectional
Operating Temperature: -55°C to 175°C minimum

Engineering Selection Recommendations

5KP90A-E3/54 (Vishay General Semiconductor - Diodes Division) is the primary direct equivalent. This part maintains identical electrical specifications to the 5KP90AE3/TR13 across all critical parameters and operates within the same temperature range. Both parts are ROHS3 compliant with unlimited moisture sensitivity rating. The part is available in Cut Tape packaging with 8400 units in stock, providing reliable supply continuity.

5KP90A (Littelfuse Inc.) is a direct functional equivalent with marginally higher peak pulse current (34.9A versus 34.2A) and identical power dissipation rating. This part is ROHS3 compliant and available in Cut Tape packaging with 4400 units in stock. The slight current increase provides additional design margin without affecting voltage protection characteristics.

15KPA90A (MDE Semiconductor Inc) is a higher-power alternative suitable for applications requiring increased transient energy absorption. This part maintains the 90V standoff and 146V clamping voltage while providing 15000W peak pulse power and 103.7A peak pulse current. The breakdown voltage is 100.5V, within acceptable tolerance. This part is available in P600 package matching the original footprint, with 1900 units in stock.

15KP90A-TP (Micro Commercial Co) provides 15000W peak pulse power in an R-6 axial package. While voltage specifications are identical, the different package footprint (R-6 versus P600) requires mechanical verification before substitution. This part is available in Cut Tape packaging with 1218 units in stock.

P6KE100A (Fairchild Semiconductor) is not recommended as a direct substitute. Although it provides similar voltage protection, the 100V reverse standoff voltage, 137V clamping voltage, 4.4A peak pulse current, and 600W power rating represent significant deviations from the original specification. The DO-15 package is mechanically incompatible with P600 footprints. This part is suitable only for applications with substantially different transient protection requirements.

Frequently Asked Questions (FAQ)

Q: Can 5KP90A-E3/54 be used as a direct replacement for 5KP90AE3/TR13?

A: Yes. The 5KP90A-E3/54 maintains identical electrical specifications across all critical parameters: 90V reverse standoff, 100V breakdown, 146V clamping voltage, 34.2A peak pulse current, and 5000W power dissipation. Both parts are ROHS3 compliant and operate across the same temperature range (-55°C to 175°C). The P600 axial package is mechanically identical.

Q: What is the difference between 5KP90A and 15KPA90A?

A: Both parts share the same 90V reverse standoff and 146V clamping voltage. The primary differences are power rating and peak pulse current. The 5KP90A is rated for 5000W peak pulse power with 34.9A peak pulse current, suitable for standard transient protection. The 15KPA90A is rated for 15000W peak pulse power with 103.7A peak pulse current, providing three times the energy absorption capacity. Selection depends on the magnitude of transient events in the application.

Q: Are 15KP90A-TP and 15KPA90A interchangeable?

A: Both parts provide 15000W peak pulse power and 90V standoff voltage. However, they use different package styles: 15KP90A-TP uses R-6 axial package while 15KPA90A uses P600 axial package. Mechanical compatibility with the PCB footprint must be verified before substitution. Electrical performance is equivalent for transient protection purposes.

Q: Why is P6KE100A not recommended as a substitute?

A: The P6KE100A has significantly different electrical specifications: 100V reverse standoff (versus 90V), 137V clamping voltage (versus 146V), 4.4A peak pulse current (versus 34.2A), and 600W power rating (versus 5000W). These differences represent a substantially lower protection capability. Additionally, the DO-15 package is mechanically incompatible with P600 footprints. This part is suitable only for applications with different transient protection requirements.

Q: What packaging options are available for substitute parts?

A: Direct equivalents are available in Cut Tape (CT) packaging: 5KP90A-E3/54 and 5KP90A. Higher-power alternatives are available in Cut Tape (15KP90A-TP) and Bulk (15KPA90A) packaging. All parts maintain through-hole axial mounting compatibility, though package footprints differ between P600 and R-6 styles. Verify PCB footprint compatibility before selection.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant. The 5KP90A-E3/54, 5KP90A, 15KP90A-TP, and 15KPA90A all meet ROHS3 requirements. Moisture sensitivity level is 1 (Unlimited) for all parts, matching the original specification.

Q: What is the operating temperature range for substitute parts?

A: All substitute parts operate across the temperature range -55°C to 175°C (TJ), matching the original 5KP90AE3/TR13 specification. This ensures thermal compatibility in applications with wide operating temperature requirements.
