5KP6.5E3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP6.5E3/TR13 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose transient voltage protection applications. This component features a 6.5V reverse standoff voltage with a 12.3V maximum clamping voltage and peak pulse current capability of 407A at 5000W peak pulse power. The device is housed in a P600 axial through-hole package and maintains active product status with full RoHS3 compliance and REACH unaffected designation.

Equivalent and substitute parts are identified based on matching or compatible electrical characteristics within the TVS diode category, specifically considering reverse standoff voltage, clamping voltage, peak pulse current ratings, and through-hole mounting compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP6.5E3/TR13 are identified based on the following critical electrical and mechanical parameters:

Primary Matching Criteria:

• Reverse standoff voltage within the 6.5V to 7.0V range
• Unidirectional channel configuration (single channel)
• Through-hole axial mounting type
• Zener diode type classification
• General-purpose application suitability
• Active product status with current availability

Secondary Compatibility Factors:

• Clamping voltage performance (11.2V to 12.3V range acceptable)
• Peak pulse current capability (100A minimum to 407A)
• Peak pulse power rating (1500W to 5000W)
• Operating temperature range (-55°C to 175°C)
• RoHS3 compliance and REACH unaffected status

The substitute parts listed below meet these criteria with variations in package form factor (DO-201 or DO-15 versus P600) and current handling capacity, which are acceptable trade-offs for equivalent circuit protection functionality.

Parameter Comparison

Engineering Selection Recommendations

LCE6.5A (Littelfuse Inc.) is the closest electrical equivalent to the 5KP6.5E3/TR13, matching the 6.5V reverse standoff voltage and 7.22V minimum breakdown voltage. This substitute maintains identical operating temperature range and RoHS3 compliance. The primary trade-off is reduced peak pulse current (100A versus 407A) and peak pulse power (1500W versus 5000W), making this substitute suitable for lower-energy transient protection applications. Package form factor differs (DO-201 versus P600), requiring PCB layout adjustment.

LCE7.0A (Littelfuse Inc.) provides a higher reverse standoff voltage of 7.0V with comparable clamping voltage (12.0V) and identical current/power ratings to the LCE6.5A. This part is appropriate for circuits requiring slightly elevated voltage thresholds while maintaining the same thermal and compliance characteristics. DO-201 package compatibility applies.

P6KE6V8A (Fairchild Semiconductor) operates at a lower reverse standoff voltage of 5.8V with higher clamping voltage (13.4V) and moderate peak pulse current (298A). This part is suitable for applications tolerating lower standoff thresholds with intermediate current handling. Operating temperature range and RoHS compliance status are not specified in available data. DO-15 package form factor differs from the original P600.

All substitute parts maintain active product status and are available in current inventory quantities. Selection should be based on specific circuit voltage thresholds, transient energy levels, and PCB package compatibility requirements.

Frequently Asked Questions (FAQ)

Q: Can the LCE6.5A directly replace the 5KP6.5E3/TR13 in all applications?

A: The LCE6.5A matches the reverse standoff voltage and breakdown characteristics but provides reduced peak pulse current (100A versus 407A) and peak pulse power (1500W versus 5000W). Direct substitution is valid only for applications where transient energy levels do not exceed 1500W peak pulse power. PCB layout modification is required due to different package form factors (DO-201 versus P600).

Q: What is the difference between the LCE6.5A and LCE7.0A?

A: Both parts are manufactured by Littelfuse with identical current and power ratings. The LCE7.0A has a higher reverse standoff voltage (7.0V versus 6.5V) and slightly higher breakdown voltage (7.78V versus 7.22V). Selection between these parts depends on the circuit's required voltage threshold. Both use DO-201 package form factor.

Q: Why does the P6KE6V8A have a lower reverse standoff voltage than the original part?

A: The P6KE6V8A operates at 5.8V reverse standoff voltage, which is lower than the 6.5V specification of the 5KP6.5E3/TR13. This part is suitable only for circuits designed to tolerate lower voltage thresholds. The higher clamping voltage (13.4V) and moderate peak pulse current (298A) make it appropriate for specific transient protection scenarios where lower standoff voltage is acceptable.

Q: Are all substitute parts RoHS3 compliant?

A: The LCE6.5A and LCE7.0A are explicitly RoHS3 compliant. The P6KE6V8A RoHS compliance status is not specified in the available technical data. Compliance verification is required before selection for applications with RoHS3 mandates.

Q: What package form factors are available for these TVS diodes?

A: The original 5KP6.5E3/TR13 uses P600 axial through-hole package. The LCE6.5A and LCE7.0A use DO-201AA (DO-27) axial through-hole package. The P6KE6V8A uses DO-204AC (DO-15) axial through-hole package. All are through-hole mounted but require different PCB pad layouts.

Q: Can these parts be used interchangeably on the same PCB without modification?

A: No. While all parts are through-hole axial devices, the different package form factors (P600, DO-201, DO-15) require distinct PCB pad spacing and hole diameter specifications. PCB layout modification is necessary for any package substitution.

Q: What is the operating temperature range for all substitute parts?

A: The LCE6.5A and LCE7.0A operate across -55°C to 175°C (TJ), matching the original 5KP6.5E3/TR13. The P6KE6V8A operating temperature range is not specified in available documentation.
