P4KE62CA-B Equivalent & Substitute Parts

Part Overview

The P4KE62CA-B is an active Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This bidirectional Zener diode operates in the DO-204AL (DO-41) axial through-hole package and provides 85V clamping voltage with 4.8A peak pulse current capability. The component is ROHS3 compliant and maintains an unlimited moisture sensitivity level (MSL 1), making it suitable for standard industrial and commercial environments. Equivalent parts are identified based on matching electrical performance parameters and package compatibility to ensure direct functional replacement in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P4KE62CA-B are identified based on the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 53V
• Voltage - Breakdown (Min): 58.9V
• Voltage - Clamping (Max) @ Ipp: 85V
• Current - Peak Pulse (10/1000µs): 4.8A minimum
• Power - Peak Pulse: 400W
• Package / Case: DO-204AL (DO-41) axial through-hole
• Operating Temperature Range: -55°C to 175°C (TJ)
• RoHS Status: ROHS3 Compliant

The P4KE62CA manufactured by Taiwan Semiconductor Corporation qualifies as a direct substitute. This part maintains identical voltage specifications (53V standoff, 58.9V breakdown, 85V clamping) and equivalent thermal performance across the full operating temperature range. The peak pulse current rating of 5A exceeds the minimum 4.8A requirement, and power dissipation remains at 400W. Both components share the same DO-204AL package configuration and ROHS3 compliance status, enabling direct functional replacement without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The P4KE62CA manufactured by Taiwan Semiconductor Corporation is a qualified substitute for the P4KE62CA-B. Both components maintain active product status and full ROHS3 compliance, ensuring regulatory alignment for current and future applications. The substitute part's 5A peak pulse current rating provides additional margin above the 4.8A specification of the original part, while maintaining identical voltage clamping and thermal performance characteristics. The DO-204AL through-hole package configuration is identical, permitting direct board-level substitution without mechanical or electrical redesign. Selection between these parts should be based on availability, lead time, and procurement requirements, as both meet all specified electrical and compliance criteria.

Frequently Asked Questions (FAQ)

Q: Can the P4KE62CA (Taiwan Semiconductor) be used as a direct replacement for the P4KE62CA-B (Littelfuse)?

A: Yes. Both parts share identical voltage specifications (53V standoff, 58.9V breakdown, 85V clamping), power dissipation (400W), operating temperature range (-55°C to 175°C), and DO-204AL package configuration. The substitute part's 5A peak pulse current rating exceeds the 4.8A requirement, providing additional design margin.

Q: Are there packaging differences between these parts?

A: The P4KE62CA-B is supplied in Bulk packaging, while the P4KE62CA is supplied in Tape & Reel (TR) format. Both use the identical DO-204AL (DO-41) axial through-hole package. Packaging format does not affect electrical performance or board-level compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the P4KE62CA-B and P4KE62CA are ROHS3 compliant with REACH Unaffected status and EAR99 export classification. Moisture sensitivity level is MSL 1 (Unlimited) for both parts.

Q: What is the significance of the higher 5A peak pulse current rating on the substitute part?

A: The substitute part's 5A rating exceeds the original 4.8A specification, providing additional transient current handling capability. This represents a performance enhancement that maintains full compatibility with the original design while offering improved margin for overvoltage transient events.

Q: Are there any thermal performance differences?

A: No. Both parts operate across the identical temperature range of -55°C to 175°C (TJ) with matching 400W peak pulse power dissipation, ensuring equivalent thermal behavior in circuit applications.
