5KP54CA-G Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The 5KP54CA-G is an active Zener-type transient voltage suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose overvoltage protection applications. This bidirectional TVS diode features a 54V reverse standoff voltage with an 87.1V maximum clamping voltage and 5000W peak pulse power rating. The component is mounted through-hole in an R-6 axial package and maintains active product status with full ROHS3 compliance. Equivalent and substitute parts are identified based on matching electrical parameters including reverse standoff voltage, clamping voltage range, peak pulse power capability, and through-hole mounting compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP54CA-G are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - Reverse Standoff (Typ): 54V (exact match required)
• Voltage - Breakdown (Min): 60V nominal range
• Voltage - Clamping (Max) @ Ipp: 87.1V ± tolerance band
• Bidirectional Channels: 1 (single channel)
• Type: Zener
• Mounting Type: Through Hole
• Applications: General Purpose
• RoHS Status: ROHS3 Compliant

Substitution Groups:

Group 1 - Direct Package Equivalent (R-6 Axial): The 5KP54CA (Littelfuse Inc.) maintains identical electrical specifications and R-6 axial package configuration, differing only in supplier device package designation (P600 vs. R-6).

Group 2 - Higher Power Rating Alternatives (P600 Package): The 15KP54CA-TP (Micro Commercial Co), 15KPA54CA (MDE Semiconductor Inc), and 30KPA54CA (MDE Semiconductor Inc) provide equivalent 54V standoff voltage protection with increased peak pulse power ratings (15kW and 30kW respectively). These parts utilize P600 axial packages and support higher current transient events while maintaining the same voltage protection window.

Parameter Comparison

Engineering Selection Recommendations

5KP54CA (Littelfuse Inc.) is the primary direct substitute, offering identical electrical performance and 5kW power rating with extended operating temperature range (-55°C to 175°C). This part maintains active product status and full ROHS3 compliance. Package transition from R-6 to P600 axial requires PCB layout verification for through-hole mounting hole spacing.

15KP54CA-TP (Micro Commercial Co) and 15KPA54CA (MDE Semiconductor Inc) provide 3x power capability (15kW) while maintaining the 54V protection voltage window. These parts support higher transient current events and extended temperature operation. Selection is appropriate for applications requiring increased energy dissipation capacity within the same voltage protection specification.

30KPA54CA (MDE Semiconductor Inc) delivers 6x power capability (30kW) with the highest peak pulse current rating (331.5A). This part accommodates the most severe transient events while maintaining 54V standoff voltage protection. Clamping voltage rises to 91.4V maximum, representing a 4.3V increase from the main part specification.

All substitute parts maintain active product status, ROHS3 compliance, and general-purpose application suitability. Selection between alternatives depends on application transient energy requirements and available PCB mounting space for package variants.

Frequently Asked Questions (FAQ)

Q: Can 5KP54CA replace 5KP54CA-G directly? A: Yes. Both parts share identical electrical specifications (54V standoff, 87.1V clamping, 5kW power rating) and through-hole mounting. The primary difference is package designation (P600 vs. R-6 axial), which requires verification of PCB hole spacing compatibility.

Q: What is the difference between R-6 and P600 packages? A: Both are through-hole axial packages for TVS diodes. R-6 and P600 designations refer to different package body dimensions and lead spacing. PCB layout must accommodate the specific package geometry; they are not interchangeable without board redesign.

Q: Can higher power-rated parts (15kW, 30kW) be used as drop-in replacements? A: Higher power-rated substitutes (15KP54CA-TP, 15KPA54CA, 30KPA54CA) maintain the 54V standoff voltage and provide equivalent or superior clamping performance. However, package changes (R-6 to P600) require PCB modification. Clamping voltage increases (87.5V to 91.4V) remain within acceptable tolerance for 54V protection circuits.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the main part specification.

Q: What determines whether a part qualifies as a substitute? A: Substitution is based on matching reverse standoff voltage (54V), maintaining clamping voltage within the protection window (87.1V ± tolerance), supporting through-hole mounting, and maintaining Zener-type bidirectional TVS functionality for general-purpose applications.

Q: Does operating temperature range affect substitution? A: The main part operates -55°C to 150°C; all substitutes extend to -55°C to 175°C. Extended temperature range does not prevent substitution but may provide additional design margin for thermal management.

Q: Can I use 30KPA54CA in a circuit designed for 5KP54CA-G? A: Yes, provided PCB layout accommodates the P600 package. The 30KPA54CA maintains 54V standoff voltage protection with superior transient energy handling. The 91.4V maximum clamping voltage represents a 4.3V increase, which remains acceptable for 54V protection specifications.
