P4KE62A-B Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The P4KE62A-B is an active Zener-type transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose voltage clamping applications. This through-hole component operates across a temperature range of -55°C to 175°C and is ROHS3 compliant. The part is currently in active production status with 998 units in stock. Equivalent and substitute parts are identified when they maintain identical electrical performance parameters and mechanical compatibility within the DO-204AL (DO-41) axial package format.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P4KE62A-B is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 53V
• Voltage - Breakdown (Min): 58.9V
• Voltage - Clamping (Max) @ Ipp: 85V
• Package / Case: DO-204AL (DO-41) axial through-hole
• Operating Temperature Range: -55°C to 175°C
• RoHS Compliance: ROHS3 Compliant
• Unidirectional Channels: 1

The P4KE62A manufactured by Taiwan Semiconductor Corporation qualifies as a direct substitute. Both parts share identical voltage specifications, thermal operating range, and package format. Minor variations in peak pulse current (4.8A vs. 5A) and packaging configuration (Bulk vs. Tape & Reel) do not affect functional interchangeability in circuit applications where the P4KE62A-B is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the P4KE62A-B (Littelfuse Inc.) and P4KE62A (Taiwan Semiconductor Corporation) are active production components with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Availability and lead time requirements
• Packaging preference (Bulk vs. Tape & Reel)
• Supplier qualification and procurement procedures
• Current inventory levels (P4KE62A-B: 998 units; P4KE62A: 1,063 units)

Both parts meet identical electrical and thermal specifications and are suitable for direct substitution in applications requiring 53V standoff voltage TVS diodes in DO-204AL axial packages.

Frequently Asked Questions (FAQ)

Q: Can the P4KE62A (Taiwan Semiconductor) replace the P4KE62A-B (Littelfuse) in existing designs?

A: Yes. Both parts maintain identical voltage clamping characteristics (85V max @ Ipp), reverse standoff voltage (53V), and operating temperature range (-55°C to 175°C). The DO-204AL axial package format is mechanically and electrically interchangeable.

Q: What is the difference between the Bulk and Tape & Reel packaging options?

A: Bulk packaging is supplied loose for manual handling and small-quantity applications. Tape & Reel packaging is configured for automated assembly processes. Both contain identical components; packaging selection depends on manufacturing process requirements.

Q: Does the 0.2A difference in peak pulse current (4.8A vs. 5A) affect substitution eligibility?

A: No. The P4KE62A's 5A peak pulse rating exceeds the P4KE62A-B specification of 4.8A, providing equivalent or superior performance in transient suppression applications. This represents a compatible variation within the P4KE series.

Q: Are both parts RoHS compliant?

A: Yes. Both the P4KE62A-B and P4KE62A are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What applications are these TVS diodes suitable for?

A: Both parts are rated for general-purpose transient voltage suppression. They are not designated for power line protection applications.
