5KP48E3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP48E3/TR13 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This component features a 48V reverse standoff voltage with an 85.5V maximum clamping voltage and 58.5A peak pulse current capability. The device is rated for 5000W peak pulse power dissipation and operates across a temperature range of -55°C to 175°C. The part is supplied in Tape & Reel packaging with P600 axial through-hole mounting. Substitute parts are necessary when addressing inventory constraints, lead time requirements, or when higher power dissipation capabilities are required for specific circuit protection designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP48E3/TR13 is determined by the following critical electrical and mechanical parameters:

Voltage Compatibility: All substitute parts maintain the 48V reverse standoff voltage specification, ensuring equivalent circuit protection thresholds. Breakdown voltage minimums range from 53.3V to 53.6V, maintaining functional equivalence within the TVS diode operating window.

Clamping Voltage: Substitute parts exhibit clamping voltages between 77.4V and 85.5V at peak pulse current. This parameter range ensures that transient suppression occurs within acceptable limits for protected circuitry.

Peak Pulse Current and Power Dissipation: Substitute parts are grouped into three power classes: 5000W (5KP48A, 5KP48A-TP), 15000W (15KPA48A), and 30000W (30KPA48A). Selection within these classes depends on the circuit's transient energy requirements.

Mechanical Compatibility: All substitute parts feature through-hole mounting with P600 or R-6 axial packages, enabling direct board-level replacement. The 5KP48A-TP variant uses R-6 package geometry, which remains mechanically compatible with standard through-hole footprints.

Temperature Rating: All substitute parts operate across the identical -55°C to 175°C temperature range, ensuring thermal performance equivalence.

Compliance and Regulatory Status: All parts maintain ROHS3 compliance and EAR99 ECCN classification, with moisture sensitivity level 1 (unlimited).

Parameter Comparison

Engineering Selection Recommendations

5KP48A and 5KP48A-TP: These parts are direct electrical equivalents to the 5KP48E3/TR13, maintaining identical 5000W peak pulse power ratings and 48V standoff voltage specifications. Both are ROHS3 compliant with EAR99 classification. The 5KP48A is supplied by Littelfuse Inc. in Cut Tape packaging with 8800 pieces in stock. The 5KP48A-TP is supplied by Micro Commercial Co in Cut Tape packaging with R-6 package geometry and 1121 pieces in stock. Selection between these options depends on packaging format availability and supplier lead time requirements.

15KPA48A: This part maintains voltage compatibility with the main part while providing 15000W peak pulse power dissipation, triple the original specification. Manufactured by MDE Semiconductor Inc with 1800 pieces in stock, this substitute is suitable for applications requiring enhanced transient energy absorption. The 77.7V clamping voltage remains within acceptable protection parameters.

30KPA48A: This part provides the highest power dissipation capability at 30000W, six times the original specification. Manufactured by MDE Semiconductor Inc with 1415 pieces in stock, this substitute addresses high-energy transient protection requirements. The 81.6V clamping voltage remains compatible with circuit protection thresholds.

P6KE51A: This part is listed as a substitute option but lacks complete electrical parameter documentation in the provided data. Fairchild Semiconductor manufacture with 18576 pieces in stock. This part should be cross-referenced against detailed datasheets to confirm voltage and power rating compatibility before selection.

All substitute parts maintain ROHS3 compliance, EAR99 ECCN classification, and unlimited moisture sensitivity level (MSL 1), ensuring regulatory and environmental equivalence to the original part.

Frequently Asked Questions (FAQ)

Q: Can the 5KP48A directly replace the 5KP48E3/TR13 in existing designs?

A: Yes. The 5KP48A maintains identical electrical specifications including 48V reverse standoff voltage, 5000W peak pulse power rating, and -55°C to 175°C operating temperature range. Both parts feature through-hole P600 axial mounting and are ROHS3 compliant. The primary difference is packaging format (Cut Tape versus Tape & Reel) and manufacturer (Littelfuse Inc. versus Microchip Technology).

Q: What is the difference between the 5KP48A and 5KP48A-TP?

A: Both parts maintain identical electrical specifications and 5000W power ratings. The 5KP48A-TP uses R-6 axial package geometry, while the 5KP48A uses P600 package geometry. Both are through-hole mounted and mechanically compatible with standard board footprints. Selection depends on specific PCB layout requirements and package availability.

Q: When should the 15KPA48A or 30KPA48A be selected instead of the 5KP48A?

A: The 15KPA48A and 30KPA48A are selected when circuit transient energy requirements exceed 5000W peak pulse power. The 15KPA48A provides 15000W capability, while the 30KPA48A provides 30000W capability. Both maintain the 48V reverse standoff voltage and -55°C to 175°C operating temperature range. Selection is based on calculated transient energy absorption requirements for the protected circuit.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (5KP48A, 5KP48A-TP, 15KPA48A, 30KPA48A) are ROHS3 compliant with EAR99 ECCN classification and MSL 1 (unlimited) moisture sensitivity level, matching the regulatory status of the 5KP48E3/TR13.

Q: What is the significance of clamping voltage differences between substitute parts?

A: Clamping voltage determines the maximum voltage transient suppression level. The 5KP48E3/TR13 clamps at 85.5V, while the 5KP48A and 15KPA48A clamp at 77.4V and 77.7V respectively, and the 30KPA48A clamps at 81.6V. All values remain within acceptable protection parameters for 48V standoff voltage applications. Lower clamping voltages provide tighter transient suppression, while higher values allow greater transient voltage before clamping occurs.

Q: Can the P6KE51A be used as a substitute?

A: The P6KE51A is listed as a substitute option but lacks complete electrical parameter documentation in available data. Direct substitution requires verification of voltage rating, clamping voltage, and power dissipation specifications against detailed manufacturer datasheets to confirm compatibility with the 5KP48E3/TR13 application requirements.

Q: What inventory considerations apply to substitute selection?

A: The 5KP48A has the highest inventory availability at 8800 pieces in stock. The 5KP48E3/TR13 has 1009 pieces, the 30KPA48A has 1415 pieces, the 5KP48A-TP has 1121 pieces, and the 15KPA48A has 1800 pieces. The P6KE51A has the highest inventory at 18576 pieces. Inventory levels should be considered alongside electrical compatibility when selecting substitutes for production requirements.
