P6KE62A-B Equivalent & Substitute Parts

Part Overview

The P6KE62A-B is a unidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This through-hole component operates with a 53V reverse standoff voltage and provides 85V maximum clamping voltage with 7.2A peak pulse current capability. The device is currently in active production status and widely stocked, with 1054 units available in inventory. Alternative equivalent parts may be required due to supply chain considerations, regional availability, or specific procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Equivalent substitution for the P6KE62A-B is determined by strict electrical and mechanical parameter matching within the P6KE series. The following parameters establish substitution validity:

• Voltage - Reverse Standoff (Typ): 53V
• Voltage - Clamping (Max) @ Ipp: 85V
• Power - Peak Pulse: 600W
• Package / Case: DO-204AC (DO-15) axial through-hole
• Type: Unidirectional Zener TVS diode
• Applications: General Purpose

The P6KE62A from Diotec Semiconductor meets all critical electrical specifications and maintains identical package geometry, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The P6KE62A from Diotec Semiconductor is a direct equivalent to the P6KE62A-B. Both devices share identical voltage specifications, power ratings, and package geometry. The Diotec variant demonstrates a marginally higher peak pulse current rating (7.4A versus 7.2A), which provides additional design margin without compromising circuit compatibility.

The Littelfuse P6KE62A-B maintains ROHS3 compliance and REACH unaffected status. The Diotec P6KE62A does not carry equivalent compliance documentation in the provided specifications. Component selection should consider compliance requirements specific to the end application and regional regulations.

Both devices are actively produced and maintain substantial inventory levels, supporting reliable procurement for production and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the Diotec P6KE62A replace the Littelfuse P6KE62A-B in existing designs?

A: Yes. Both devices are electrically and mechanically equivalent. The Diotec variant meets or exceeds all critical electrical parameters and uses the identical DO-204AC (DO-15) package. Direct substitution is valid for general-purpose TVS applications.

Q: What is the significance of the 7.2A versus 7.4A peak pulse current difference?

A: The Diotec device provides 0.2A higher peak pulse current capability. This represents additional design margin and does not create compatibility issues. Both ratings support the same 600W peak pulse power specification.

Q: Are there temperature range differences between these parts?

A: The Littelfuse device operates from -55°C to 175°C, while the Diotec device operates from -50°C to 175°C. The Diotec lower temperature limit is 5°C higher. For applications requiring operation below -50°C, the Littelfuse part is required.

Q: Do package dimensions differ between manufacturers?

A: No. Both devices use the DO-204AC (DO-15) axial through-hole package with identical mechanical specifications, supporting direct board-level substitution without layout modifications.

Q: What compliance certifications apply to each part?

A: The Littelfuse P6KE62A-B carries ROHS3 compliance and REACH unaffected status. The Diotec P6KE62A compliance status is not specified in available documentation. Verify compliance requirements for your specific application before selection.
