5KP48A-TP Equivalent & Substitute Parts

Part Overview

The 5KP48A-TP is an active Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This unidirectional zener diode operates across a temperature range of -55°C to 175°C and provides 5000W peak pulse power dissipation with a 48V reverse standoff voltage. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1), making it suitable for standard industrial and commercial circuit protection requirements. Equivalent and substitute parts are identified based on matching electrical performance parameters and mechanical compatibility within the TVS diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP48A-TP are qualified based on the following critical parameters:

• Voltage - Reverse Standoff (Typ): 48V
• Voltage - Breakdown (Min): 53.3V or 53.6V
• Voltage - Clamping (Max) @ Ipp: 77.4V to 81.6V range
• Mounting Type: Through Hole, Axial package
• Type: Zener, Unidirectional
• Operating Temperature: -55°C ~ 175°C (TJ)
• RoHS Status: ROHS3 Compliant

Substitutes are grouped into two categories: direct equivalents (matching 5000W power rating and R-6/P600 package variants) and higher-power alternatives (15kW and 30kW ratings for applications requiring enhanced transient protection).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (5KP48A by Littelfuse Inc.): This part matches the 5KP48A-TP across all critical electrical parameters including 48V reverse standoff voltage, 77.4V clamping voltage, and 5000W peak pulse power. Both parts are ROHS3 compliant and active products. The primary difference is the package variant (P600 versus R-6), which remains compatible for through-hole mounting applications. This substitute is suitable for direct replacement in existing designs.

Higher-Power Alternatives (15KPA48A and 30KPA48A by MDE Semiconductor Inc): These parts maintain the same 48V reverse standoff voltage and comparable clamping voltage characteristics (77.7V and 81.6V respectively) but provide increased peak pulse power ratings of 15kW and 30kW. Both are ROHS3 compliant and active products. These substitutes are applicable in applications requiring enhanced transient suppression capability or where higher peak current handling is necessary.

P6KE51A (Fairchild Semiconductor): This part is listed as an active product but lacks complete electrical parameter specification in the provided data. Substitution suitability cannot be determined based on available information.

Frequently Asked Questions (FAQ)

Q: Can the 5KP48A by Littelfuse be used as a direct replacement for the 5KP48A-TP?

A: Yes. Both parts share identical electrical specifications: 48V reverse standoff voltage, 53.3V minimum breakdown voltage, and 77.4V maximum clamping voltage at peak pulse current. Both are rated for 5000W peak pulse power and operate across -55°C to 175°C. The package designation differs (P600 versus R-6), but both are through-hole axial configurations suitable for standard PCB mounting.

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

A: The 15KPA48A and 30KPA48A provide increased peak pulse power dissipation (15kW and 30kW respectively) compared to the 5kW rating of the 5KP48A-TP. The reverse standoff voltage remains 48V across all three parts. Higher-power variants are selected when circuit transient events exceed the 5kW dissipation capability of the base 5KP48A-TP.

Q: Are all substitute parts ROHS3 compliant?

A: The 5KP48A (Littelfuse), 15KPA48A, and 30KPA48A are all ROHS3 compliant. The P6KE51A compliance status is not specified in the available data.

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

A: The 5KP48A-TP, 5KP48A, 15KPA48A, and 30KPA48A all operate across -55°C to 175°C junction temperature. Operating temperature range for the P6KE51A is not specified.

Q: Can package differences affect circuit compatibility?

A: The 5KP48A-TP uses R-6 axial packaging while the Littelfuse 5KP48A and MDE alternatives use P600 axial packaging. Both are through-hole configurations with compatible lead spacing for standard PCB layouts. Physical dimensions may vary slightly, requiring verification against PCB footprint specifications.
