Part Overview

The 5KP30AE3/TR13 is a unidirectional transient voltage suppressor diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This through-hole axial component operates across a wide temperature range (-55°C to 175°C) and is RoHS3 compliant with unlimited moisture sensitivity rating. The part is currently in active production status with 792 pieces available in new original inventory.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits selection from multiple qualified manufacturers offering identical or functionally compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP30AE3/TR13 are classified into two categories based on electrical and mechanical compatibility:

Direct Substitutes maintain identical electrical specifications (30V reverse standoff, 33.3V minimum breakdown, 48.4V maximum clamping voltage, 103A peak pulse current, 5000W peak pulse power) and P600 axial through-hole packaging. These parts differ only in manufacturer, packaging format (tape & reel versus cut tape), or automotive-grade qualification. Direct substitutes are interchangeable without circuit redesign.

Similar Substitutes share the same 30V reverse standoff voltage and P600 axial through-hole package but differ in one or more electrical parameters: peak pulse current, clamping voltage, or peak pulse power rating. These parts are functionally compatible for applications where higher power dissipation or current handling is acceptable, or where lower ratings do not compromise circuit protection requirements.

Key Parameters Determining Substitution:

• Voltage - Reverse Standoff: 30V (fixed requirement)
• Voltage - Clamping (Max) @ Ipp: 48.4V ±tolerance
• Current - Peak Pulse (10/1000µs): 103A minimum
• Power - Peak Pulse: 5000W minimum
• Mounting Type: Through Hole
• Package / Case: P600 Axial

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Electrically Identical):

The 5KP30A-E3/54 (Vishay General Semiconductor) and 5KP30A (Diotec Semiconductor) are direct electrical equivalents with identical voltage and current ratings. Both are RoHS3 compliant and active production status. The 5KP30A-E3/54 is available in higher inventory (8100 pieces) in cut tape packaging. The 5KP30A from Diotec offers 4345 pieces in tape & reel format. Selection between these options depends on packaging preference and supply availability.

The 5KP30AHE3/54 (Vishay General Semiconductor) is an automotive-grade variant (AEC-Q101 qualified) with identical electrical specifications. This part is suitable for applications requiring automotive qualification and is available with 1636 pieces in inventory.

Higher Power Alternatives:

The 15KPA30A (Good-Ark Semiconductor) and 30KPA30A (MDE Semiconductor Inc) provide higher peak pulse power ratings (15kW and 30kW respectively) while maintaining the 30V reverse standoff voltage. These parts accommodate higher transient energy levels and are suitable for applications with more severe overvoltage conditions. Both maintain P600 axial through-hole packaging and RoHS3 compliance. The 30KPA30A extends to 175°C maximum junction temperature, matching the main part specification.

Lower Power Alternative:

The LCE28A (Littelfuse Inc.) operates at 28V reverse standoff with reduced peak pulse current (33A) and power (1500W). This part is suitable only for applications where lower protection levels are acceptable and is packaged in DO-201AA format rather than P600.

Packaging Consideration:

The 5KP30A-TP (Micro Commercial Co) uses R-6 axial packaging instead of P600. Verify mechanical fit in the target application before selection.

Frequently Asked Questions (FAQ)

Q: Can I use 5KP30A-E3/54 as a direct replacement for 5KP30AE3/TR13?

A: Yes. Both parts share identical electrical specifications: 30V reverse standoff, 33.3V minimum breakdown, 48.4V maximum clamping voltage, 103A peak pulse current, and 5000W peak pulse power. The primary difference is packaging format (cut tape versus tape & reel) and manufacturer. Verify tape format compatibility with your assembly equipment.

Q: What is the difference between 5KP30AHE3/54 and 5KP30A-E3/54?

A: The 5KP30AHE3/54 is automotive-grade (AEC-Q101 qualified) while 5KP30A-E3/54 is general-purpose. Electrical specifications are identical. Select the automotive variant only if your application requires automotive qualification.

Q: Can I substitute 15KPA30A or 30KPA30A for the 5KP30AE3/TR13?

A: These parts are functionally compatible for overvoltage protection at 30V standoff voltage but provide higher peak pulse power ratings (15kW and 30kW versus 5kW). Use these substitutes only when circuit analysis confirms that higher clamping voltage (50.7V and 55.2V respectively) and higher peak pulse current do not compromise circuit protection requirements. These parts are suitable for applications with more severe transient conditions.

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

A: LCE28A operates at 28V reverse standoff versus 30V for the main part. This represents a lower protection threshold and reduced peak pulse handling (33A versus 103A, 1500W versus 5000W). This part is listed as a similar substitute only for applications where lower protection levels are acceptable. Verify circuit requirements before selection.

Q: Does package type affect electrical performance?

A: No. P600 and R-6 axial packages are mechanically different but electrically equivalent for the same part number. Package selection depends on PCB layout and assembly equipment compatibility. Verify mechanical fit and lead spacing in your specific application.

Q: Are all listed substitutes RoHS3 compliant?

A: Yes. All parts listed maintain RoHS3 compliance status. Verify REACH compliance status with your supplier if required for your application region.

Q: What is the minimum peak pulse current requirement for substitution?

A: The main part 5KP30AE3/TR13 specifies 103A peak pulse current at 10/1000µs waveform. Direct substitutes must maintain this specification. Higher-rated parts (15KPA30A at 297.8A, 30KPA30A at 548.9A) exceed this requirement and are acceptable. Lower-rated parts (LCE28A at 33A) do not meet this requirement and are suitable only for reduced-protection applications.

Q: Can I mix different manufacturers in the same circuit?

A: Yes, provided all selected parts meet the electrical specifications required by your circuit design. Mixing manufacturers is acceptable from an engineering standpoint. Verify procurement and quality assurance procedures with your supply chain management.
