5KP64A-G Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The 5KP64A-G is an active-status unidirectional Zener-type transient voltage suppressor manufactured by Comchip Technology. This through-hole axial R-6 package TVS diode is designed for general-purpose transient voltage suppression applications with a 64V reverse standoff voltage and 5kW peak pulse power rating. Substitute parts are identified to address inventory availability, extended temperature operating ranges, higher power dissipation requirements, or alternative packaging preferences while maintaining electrical compatibility within the specified parameter tolerances.

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP64A-G is determined by the following critical parameters:

Voltage - Reverse Standoff (Typ): Must equal 64V
Voltage - Breakdown (Min): Must fall within 71.1V to 71.5V range
Voltage - Clamping (Max) @ Ipp: Must fall within 103V to 104.2V range
Unidirectional Channels: Must equal 1
Type: Must be Zener
Mounting Type: Must be Through Hole
Applications: General Purpose
RoHS Status: ROHS3 Compliant preferred

Substitute parts are grouped into two categories:

Category A - Direct Electrical Equivalents (Same Power Rating): Parts maintaining 5kW peak pulse power with identical voltage parameters and R-6 or P600 axial packages.

Category B - Higher Power Alternatives: Parts with 15kW or 30kW peak pulse power ratings, suitable for applications requiring enhanced transient suppression capability while maintaining the same voltage specifications.

Engineering Selection Recommendations

Direct Substitutes (5KP64A, 5KP64A-E3/54): These parts maintain identical electrical specifications to the 5KP64A-G with 5kW peak pulse power. The 5KP64A-E3/54 from Vishay is ROHS3 compliant and rated to -55°C to 175°C, providing extended upper temperature operation. The 5KP64A from Diotec offers equivalent performance with extended temperature range (-50°C to 175°C) and higher inventory availability (38,400 units).

Higher Power Alternatives (15KPA64A, 30KPA64A): Both MDE Semiconductor parts maintain the 64V reverse standoff voltage with voltage breakdown and clamping parameters within acceptable tolerance. The 15KPA64A provides 15kW peak pulse power (3× the original rating), while the 30KPA64A provides 30kW peak pulse power (6× the original rating). Both are ROHS3 compliant and rated to -55°C to 175°C. These are suitable for applications requiring enhanced transient suppression margin or higher surge current handling.

Frequently Asked Questions (FAQ)

Q: Can I use the 5KP64A-E3/54 as a direct replacement for the 5KP64A-G?

A: Yes. Both parts share identical voltage specifications (64V reverse standoff, 71.1V breakdown minimum, 103V clamping maximum) and 5kW peak pulse power. The 5KP64A-E3/54 offers ROHS3 compliance and extended temperature range (-55°C to 175°C versus -55°C to 150°C). Package differences exist (P600 versus R-6 axial), but both are through-hole axial configurations suitable for standard PCB mounting.

Q: What is the difference between the 5KP64A-G and the 15KPA64A?

A: The primary difference is peak pulse power: 5kW versus 15kW. Both maintain 64V reverse standoff voltage with voltage breakdown and clamping parameters within specification tolerance. The 15KPA64A handles 144.9A peak pulse current compared to 48.54A for the 5KP64A-G. Selection depends on transient suppression margin requirements and circuit peak current exposure.

Q: Are the 15KPA64A and 30KPA64A interchangeable with the 5KP64A-G?

A: Electrically, yes, within the voltage parameter tolerances specified. Both maintain 64V reverse standoff voltage. The 30KPA64A provides 30kW peak pulse power (6× the original) and handles 291.3A peak pulse current. These higher-power variants are suitable for applications requiring enhanced transient suppression capability or higher surge current handling. Physical package compatibility (P600 axial through-hole) is maintained.

Q: Does package type affect substitution eligibility?

A: Package type does not affect electrical substitution eligibility provided both are through-hole axial configurations. The 5KP64A-G uses R-6 axial packaging, while most substitutes use P600 axial packaging. Both are standard through-hole axial packages compatible with conventional PCB mounting. Verify PCB footprint compatibility before selection.

Q: Which substitute offers the best compliance profile?

A: The 5KP64A-E3/54 from Vishay and both MDE Semiconductor parts (15KPA64A, 30KPA64A) are ROHS3 compliant with REACH unaffected or REACH information available upon request status. All three are suitable for applications with strict compliance requirements.
