P6KE62A Equivalent & Substitute Parts

Part Overview

The P6KE62A is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection applications. This component operates with a 53V reverse standoff voltage and provides 85V maximum clamping voltage with 7.1A peak pulse current capability in a through-hole DO-15 package. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications requiring identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6KE62A are qualified based on strict electrical and mechanical parameter matching within acceptable tolerances for TVS diode applications. The substitution criteria are:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 53V
• Voltage - Breakdown (Min): 58.9V
• Voltage - Clamping (Max) @ Ipp: 85V
• Current - Peak Pulse (10/1000µs): 7.1A minimum
• Power - Peak Pulse: 600W
• Type: Unidirectional Zener
• Package: DO-15 / DO-204AC through-hole configuration

Acceptable Variation Ranges: Peak pulse current may vary within ±5% of the specified 7.1A value. Clamping voltage and standoff voltage must remain within the specified limits. All substitute parts must maintain identical package form factor and through-hole mounting compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain identical critical electrical specifications for voltage clamping, standoff voltage, and power dissipation. Peak pulse current ratings show minor variation (7.1A to 7.4A), all within acceptable tolerance for general-purpose TVS applications.

P6KE62A (Diodes Incorporated): Primary reference part with full RoHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating. Operating temperature range -55 to 175°C.

P6KE62A (Diotec Semiconductor): Electrically equivalent with 7.4A peak pulse current. RoHS status not applicable. Operating temperature range -50 to 175°C. Suitable for applications where the upper temperature limit of -50°C minimum is acceptable.

TP6KE62A (Littelfuse Inc.): Automotive-grade component with AEC-Q101 qualification. Peak pulse current 7.2A. Full RoHS3 compliance and REACH unaffected status. Operating temperature range -55 to 175°C. Recommended for automotive and mission-critical applications requiring automotive-grade qualification.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Diotec P6KE62A for the Diodes Incorporated P6KE62A? A: Yes. Both parts share identical voltage specifications (53V standoff, 85V clamping) and power rating (600W). The Diotec variant provides 7.4A peak pulse current, which exceeds the 7.1A requirement. Operating temperature minimum differs by 5°C (-50°C vs -55°C); verify this meets your application requirements.

Q: Is the Littelfuse TP6KE62A suitable for non-automotive applications? A: Yes. The TP6KE62A meets all electrical and mechanical requirements for general-purpose TVS applications. The automotive-grade designation and AEC-Q101 qualification provide additional quality assurance but do not restrict use in non-automotive circuits.

Q: What is the significance of the DO-15 and DO-204AC package designations? A: DO-15 and DO-204AC refer to the same through-hole axial package form factor. These designations are equivalent and interchangeable for PCB layout and component placement purposes.

Q: Are there any compliance differences between the three parts? A: The Diodes Incorporated and Littelfuse parts carry ROHS3 compliance and REACH unaffected status. The Diotec part lists RoHS status as not applicable. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: Can I use these parts interchangeably in existing designs? A: Yes, provided the application does not depend on specific manufacturer certifications or compliance documentation. All three parts maintain identical package form factor, mounting type, and critical electrical parameters within acceptable engineering tolerances.
