3KP60C Equivalent & Substitute Parts

Part Overview

The 3KP60C is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient voltage protection applications. This component features a 60V reverse standoff voltage rating and 3000W peak pulse power handling capability in a through-hole P600 axial package. The 3KP60C is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3KP60C is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff (Typ): 60V (exact match required)
• Voltage - Breakdown (Min): within acceptable tolerance range
• Voltage - Clamping (Max) @ Ipp: within acceptable tolerance range
• Bidirectional Channels: 1 (single channel required)
• Type: Zener (TVS diode technology)

Mechanical Compatibility Criteria:

• Package / Case: P600 or R-6 axial through-hole packages (pin-compatible)
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C to 175°C (TJ) minimum

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The identified substitute parts maintain the 60V reverse standoff voltage specification and operate within the same temperature range. Variations in peak pulse current and power ratings reflect different product series within the TVS diode family, with higher-rated alternatives providing enhanced transient protection capability.

Parameter Comparison

Engineering Selection Recommendations

5KP60CA (Littelfuse Inc.): This part is the primary active substitute for the obsolete 3KP60C. Both components share identical reverse standoff voltage (60V), operating temperature range (-55°C to 175°C), and through-hole axial package configuration (P600). The 5KP60CA maintains ROHS3 compliance and unlimited moisture sensitivity rating. The higher peak pulse power rating (5000W versus 3000W) and increased peak pulse current (52.7A versus 31A) provide enhanced transient protection capability while maintaining electrical compatibility within the 60V protection class. The 5KP60CA is actively manufactured and readily available.

30KP60CA-TP (Micro Commercial Co): This part offers the highest power dissipation capability (30000W) among the substitute options while maintaining the 60V reverse standoff voltage specification. The 30KP60CA-TP is manufactured by Micro Commercial Co and carries active product status with ROHS3 compliance. The package designation (R-6 axial) differs from the original P600, but both are through-hole axial configurations with compatible pin spacing for direct substitution. This part is suitable for applications requiring maximum transient energy absorption.

Both substitute parts satisfy the core electrical and mechanical requirements for 3KP60C replacement and maintain full regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the 5KP60CA directly replace the 3KP60C in existing designs?

A: Yes. The 5KP60CA maintains the critical electrical parameters: 60V reverse standoff voltage, identical operating temperature range (-55°C to 175°C), and compatible through-hole P600 axial package. The increased power rating (5000W versus 3000W) provides enhanced protection without compromising compatibility.

Q: What is the difference between P600 and R-6 packages?

A: Both P600 and R-6 are through-hole axial package designations for TVS diodes. The R-6 package used by the 30KP60CA-TP is mechanically compatible with P600 footprints, allowing direct board-level substitution.

Q: Why does the 30KP60CA-TP have a significantly higher power rating?

A: The 30KP60CA-TP is designed for high-energy transient suppression applications. The 30000W peak pulse power rating reflects a different product series within the TVS diode family, offering superior energy absorption capability for demanding protection requirements while maintaining the same 60V voltage class.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 5KP60CA and 30KP60CA-TP are both ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), matching the compliance profile of the original 3KP60C.

Q: What determines whether a part can substitute for the 3KP60C?

A: Substitution is determined by: (1) identical 60V reverse standoff voltage, (2) compatible operating temperature range (-55°C to 175°C minimum), (3) through-hole axial package configuration, (4) single bidirectional channel, (5) Zener TVS diode technology, and (6) ROHS3 compliance. Variations in peak pulse current and power ratings are acceptable as they represent enhanced protection capability within the same voltage class.
