P6KE62 Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The P6KE62 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., housed in a DO-204AC (DO-15) axial through-hole package. This component is designed for general-purpose transient voltage protection applications with a peak pulse power rating of 600W and a reverse standoff voltage of 53V. The P6KE62 is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6KE62 is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Unidirectional channel configuration (1 channel required)
• Reverse standoff voltage: 53V nominal
• Peak pulse power rating: 600W
• Voltage clamping characteristics within acceptable operational range
• Zener diode type classification

Mechanical Equivalence Criteria:

• Through-hole mounting type
• DO-204AC (DO-15) axial package configuration

The P6KE62A from Diotec Semiconductor meets all specified electrical and mechanical parameters for direct substitution. Both parts maintain identical reverse standoff voltage (53V), peak pulse power (600W), unidirectional channel count (1), and package form factor (DO-15 axial through-hole).

Parameter Comparison

Engineering Selection Recommendations

The P6KE62A from Diotec Semiconductor is a direct functional equivalent for the obsolete P6KE62 from Littelfuse Inc. Both components share identical electrical specifications for reverse standoff voltage (53V) and peak pulse power rating (600W), with compatible voltage clamping characteristics. The P6KE62A maintains active product status, ensuring ongoing availability and supply chain continuity.

The P6KE62A exhibits a lower maximum clamping voltage (85V versus 89.25V) and a narrower operating temperature range (-50°C to 175°C versus -55°C to 175°C). These parameter variations remain within acceptable substitution tolerances for general-purpose transient voltage protection applications. The identical DO-15 axial through-hole package configuration ensures mechanical compatibility without PCB redesign.

Selection of the P6KE62A is appropriate for applications requiring direct replacement of the obsolete P6KE62 without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the P6KE62A be used as a direct replacement for the P6KE62 without PCB modifications?

A: Yes. Both components use the DO-15 axial through-hole package configuration with identical pin spacing and mounting requirements. No PCB layout changes are necessary.

Q: What are the key electrical differences between the P6KE62 and P6KE62A?

A: The primary differences are the maximum clamping voltage (P6KE62: 89.25V; P6KE62A: 85V) and the minimum breakdown voltage (P6KE62: 55.8V; P6KE62A: 58.9V). Both maintain the same 53V reverse standoff voltage and 600W peak pulse power rating. The P6KE62A also specifies a peak pulse current of 7.4A.

Q: Are there temperature range considerations when substituting the P6KE62A for the P6KE62?

A: The P6KE62A operates from -50°C to 175°C, compared to the P6KE62 range of -55°C to 175°C. Applications requiring operation below -50°C ambient temperature should be evaluated for compatibility.

Q: What is the product status difference between these parts?

A: The P6KE62 is classified as obsolete, while the P6KE62A maintains active product status. This ensures long-term availability and supply chain support for the P6KE62A.

Q: Are both parts RoHS compliant?

A: The P6KE62 is ROHS3 compliant. The P6KE62A RoHS status is listed as not applicable by the manufacturer.
