P6KE62-B Equivalent & Substitute Parts
Part Overview
The P6KE62-B is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component features a 53V reverse standoff voltage with 89.25V maximum clamping voltage and 600W peak pulse power rating in a through-hole DO-204AC (DO-15) axial package. The P6KE62-B is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation
Substitution eligibility for the P6KE62-B is determined by the following critical parameters:
- Voltage - Reverse Standoff (Typ): 53V
- Voltage - Clamping (Max) @ Ipp: Maximum 89.25V
- Power - Peak Pulse: 600W
- Unidirectional Channels: 1
- Package / Case: DO-204AC / DO-15 Axial
- Mounting Type: Through Hole
The identified substitute parts maintain the same reverse standoff voltage (53V) and peak pulse power rating (600W), with clamping voltages at or below the original specification. Both substitute parts are available in the identical DO-204AC (DO-15) axial through-hole package, ensuring mechanical and electrical compatibility in existing circuit designs.

Engineering Selection Recommendations
Both P6KE62A-B and P6KE62A are functionally equivalent substitutes for the obsolete P6KE62-B. The P6KE62A-B (Littelfuse Inc.) is the preferred substitute, maintaining identical manufacturer lineage, ROHS3 compliance, and operating temperature range (-55°C ~ 175°C). This part is currently in active production status with 1054 units in stock.
The P6KE62A (Diotec Semiconductor) provides an alternative from a different manufacturer with active product status and higher inventory availability (6300 units). This part meets all critical electrical parameters and package requirements. The operating temperature minimum is -50°C versus -55°C for the Littelfuse variant, which may be a consideration for applications requiring extended low-temperature performance.
Both substitutes feature improved clamping voltage performance (85V maximum versus 89.25V) compared to the original part, providing enhanced transient suppression characteristics within the same power envelope.
Frequently Asked Questions (FAQ)
Q: Can P6KE62A-B and P6KE62A be used interchangeably with P6KE62-B?
A: Yes. Both parts maintain the critical electrical parameters: 53V reverse standoff voltage, 600W peak pulse power, and identical DO-204AC (DO-15) axial through-hole packaging. The clamping voltage specifications of both substitutes (85V maximum) are superior to the original part (89.25V maximum).
Q: What is the difference between P6KE62A-B and P6KE62A?
A: P6KE62A-B is manufactured by Littelfuse Inc. with ROHS3 compliance and operating temperature range of -55°C to 175°C. P6KE62A is manufactured by Diotec Semiconductor with an operating temperature range of -50°C to 175°C. Both are electrically equivalent for the specified parameters.
Q: Are there any package compatibility concerns?
A: No. All three parts use the identical DO-204AC (DO-15) axial through-hole package. Direct board-level substitution is possible without circuit layout modifications.
Q: Why is the clamping voltage lower in the substitute parts?
A: The substitute parts (P6KE62A-B and P6KE62A) specify 85V maximum clamping voltage compared to 89.25V for the original P6KE62-B. This represents improved performance characteristics within the same power rating and is not a limitation for substitution purposes.
Q: Which substitute should be selected for new designs?
A: Selection should be based on procurement availability, supply chain considerations, and compliance requirements. P6KE62A-B maintains Littelfuse manufacturer continuity and ROHS3 compliance. P6KE62A offers higher inventory availability from Diotec Semiconductor.
