Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP58A-G is determined by the following critical electrical parameters:

• Voltage - Reverse Standoff (Typ): 58V
• Voltage - Clamping (Max) @ Ipp: 93.6V nominal range
• Current - Peak Pulse (10/1000µs): minimum 53.42A
• Mounting Type: Through Hole configuration
• Package Type: Axial lead format

The 15KPA58A from MDE Semiconductor Inc qualifies as a direct substitute based on matching reverse standoff voltage (58V), clamping voltage specification (93.8V), and through-hole axial mounting configuration. The substitute part exceeds the peak pulse current requirement (161A vs. 53.42A) and provides higher peak pulse power handling (15000W vs. 5000W), making it suitable for applications requiring enhanced transient protection capability.

Parameter Comparison

Engineering Selection Recommendations

Both the 5KP58A-G and 15KPA58A are active production components with ROHS3 compliance and EAR99 export classification. Selection between these parts should be based on the following criteria:

Select 5KP58A-G when:

• Application requires the R-6 axial package form factor
• Peak pulse current requirement is limited to 53.42A or less
• Thermal dissipation is constrained to 5000W peak pulse power
• Operating temperature does not exceed 150°C

Select 15KPA58A when:

• Higher peak pulse current handling (161A) is required
• Application demands greater transient energy absorption (15000W)
• Operating temperature range extends to 175°C
• P600 axial package is compatible with circuit board layout
• Enhanced protection margin is desired for high-stress transient environments

Both parts maintain identical reverse standoff voltage (58V) and clamping voltage characteristics (93.6V to 93.8V), ensuring functional equivalence in voltage regulation performance.

Frequently Asked Questions (FAQ)

Q: Can the 15KPA58A directly replace the 5KP58A-G in existing designs?

A: Yes, from an electrical standpoint. Both parts share the same 58V reverse standoff voltage and nearly identical clamping voltage specifications (93.6V vs. 93.8V). However, the physical package differs (R-6 vs. P600 axial), so mechanical fit on the circuit board must be verified before substitution.

Q: What is the primary difference between these two TVS diodes?

A: The 15KPA58A provides significantly higher peak pulse current (161A vs. 53.42A) and peak pulse power (15000W vs. 5000W), along with an extended operating temperature range (-55 to 175°C vs. -55 to 150°C). The 5KP58A-G is suitable for standard transient protection, while the 15KPA58A is designed for high-energy transient suppression applications.

Q: Are both parts RoHS compliant?

A: Yes, both the 5KP58A-G and 15KPA58A are ROHS3 compliant and suitable for applications requiring environmental compliance.

Q: Does the axial package difference affect circuit board compatibility?

A: Yes. The 5KP58A-G uses an R-6 package while the 15KPA58A uses a P600 package. Although both are axial through-hole formats, the physical dimensions and lead spacing may differ. Verify package dimensions against your circuit board layout and hole spacing before substitution.

Q: What applications are these TVS diodes suitable for?

A: Both parts are classified for general-purpose transient voltage protection. They are used in circuits requiring protection against voltage spikes and transient overvoltage events across a 58V nominal protection level.
