5KP60C-B Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The 5KP60C-B is a bidirectional Zener transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This through-hole P600 axial package component operates across a temperature range of -55°C to 175°C and provides 5000W peak pulse power dissipation. The 5KP60C-B is currently classified as obsolete, necessitating identification of active equivalent and substitute components that maintain functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP60C-B is determined by the following critical parameters:

Primary Compatibility Criteria:

• Voltage - Reverse Standoff (Typ): 60V
• Bidirectional Channels: 1
• Mounting Type: Through Hole
• Package / Case: P600 or R-6 Axial
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• Type: Zener
• RoHS Status: ROHS3 Compliant

Secondary Electrical Parameters:

• Voltage - Breakdown (Min): 63.18V to 68.4V range
• Voltage - Clamping (Max) @ Ipp: 96.8V to 107V range
• Power - Peak Pulse: 5000W minimum

Substitute parts are grouped into two categories based on package compatibility and power rating:

Group 1 - P600 Package, 5kW Rating: 5KP60CA, 5KP60CA-B, SLD60-018-B, 5KP60CE3/TR13. These maintain identical package geometry and power dissipation specifications.

Group 2 - R-6 Package, Higher Power Ratings: 15KP60CA-TP (15kW), 30KP60CA-TP (30kW). These offer increased power handling capability with alternative axial package geometry.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (P600 Package, 5kW Rating):

5KP60CA and 5KP60CA-B are functionally equivalent to the 5KP60C-B with active product status. Both maintain identical 60V reverse standoff voltage, P600 axial package geometry, 5000W peak pulse power rating, and -55°C to 175°C operating temperature range. Voltage clamping values (96.8V) are within acceptable substitution parameters. 5KP60CA is available in Cut Tape packaging, while 5KP60CA-B is supplied in Bulk packaging.

SLD60-018-B, manufactured by Littelfuse Inc., provides equivalent electrical performance with automotive-grade qualification (AEC-Q101) and active product status. This component is suitable for applications requiring automotive-level reliability assurance.

5KP60CE3/TR13, manufactured by Microchip Technology, offers equivalent 60V standoff voltage and 5000W power rating in P600 package with slightly elevated clamping voltage (107V). This component is available in Tape & Reel packaging.

Higher Power Alternative (R-6 Package):

15KP60CA-TP and 30KP60CA-TP, manufactured by Micro Commercial Co, provide increased power dissipation capability (15kW and 30kW respectively) while maintaining 60V reverse standoff voltage and -55°C to 175°C operating temperature range. These components use R-6 axial package geometry and are suitable for applications requiring enhanced transient energy absorption. Selection of higher power ratings depends on circuit-level transient energy requirements.

All substitute parts maintain ROHS3 compliance and are currently in active production status.

Frequently Asked Questions (FAQ)

Q: Can 5KP60CA directly replace 5KP60C-B in existing PCB designs?

A: Yes. Both components share identical P600 axial through-hole package geometry, 60V reverse standoff voltage, 5000W peak pulse power rating, and -55°C to 175°C operating temperature range. PCB footprints and lead spacing are compatible. Voltage clamping characteristics (96.8V vs 101.64V) fall within acceptable substitution parameters for general-purpose overvoltage protection applications.

Q: What is the difference between 5KP60CA and 5KP60CA-B?

A: Both components are electrically identical with matching 60V standoff voltage, 96.8V clamping voltage, and 5000W power rating. The primary difference is packaging: 5KP60CA is supplied in Cut Tape (CT) format, while 5KP60CA-B is supplied in Bulk packaging. Selection depends on procurement and assembly process requirements.

Q: Why would I select 15KP60CA-TP or 30KP60CA-TP over 5KP60CA?

A: Higher power-rated alternatives (15kW and 30kW) are selected when circuit transient energy exceeds 5000W peak pulse capability. These components maintain 60V reverse standoff voltage and -55°C to 175°C operating temperature range but use R-6 axial package geometry instead of P600. PCB layout modifications are required to accommodate the different package footprint.

Q: Is SLD60-018-B suitable for automotive applications?

A: Yes. SLD60-018-B carries AEC-Q101 automotive qualification and is manufactured by Littelfuse Inc. with active product status. This component is appropriate for automotive-grade overvoltage protection requirements while maintaining electrical equivalence to 5KP60C-B.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute components (5KP60CA, 5KP60CA-B, SLD60-018-B, 5KP60CE3/TR13, 15KP60CA-TP, 30KP60CA-TP) are ROHS3 compliant and suitable for applications with RoHS regulatory requirements.

Q: What is the impact of different clamping voltages among substitute parts?

A: Clamping voltage determines the maximum voltage level at which the TVS diode conducts during transient events. The 5KP60C-B specifies 101.64V maximum clamping, while most substitutes range from 96.8V to 107V. Selection depends on protected circuit voltage tolerance specifications. Lower clamping voltages provide tighter voltage regulation; higher clamping voltages allow greater voltage excursion before conduction.
