5KP6.5CE3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP6.5CE3/TR13 is a transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This bidirectional Zener diode operates with a reverse standoff voltage of 6.5V and provides peak pulse power handling of 5000W (5kW). The component is supplied in Tape & Reel packaging with P600 axial through-hole mounting configuration and maintains Active product status with full RoHS3 compliance.

Substitute parts are identified when equivalent electrical performance can be achieved within the allowed parameter ranges for TVS diode applications, accounting for variations in package type, peak pulse current ratings, and clamping voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of TVS diodes is determined by compatibility across the following critical parameters:

Voltage Compatibility: The reverse standoff voltage and breakdown voltage must fall within acceptable ranges for the protected circuit. Substitute parts with reverse standoff voltages of 5.8V remain functionally equivalent to the 6.5V main part within general-purpose protection applications.

Current and Power Handling: Peak pulse current (Ipp) and peak pulse power ratings define the transient energy absorption capability. Substitute parts with lower peak pulse current ratings (57.1A to 746A) represent reduced protection capacity but remain valid for applications with lower transient stress levels.

Clamping Voltage: The maximum clamping voltage at peak pulse current determines the voltage level at which the diode clamps transients. Variations in clamping voltage (10.5V to 13.4V) are acceptable within TVS diode substitution logic, as they reflect different device geometries and current ratings.

Package and Mounting: Through-hole axial packages (P600, DO-201, DO-15) are mechanically and electrically interchangeable in PCB designs that accommodate axial lead spacing and hole diameter variations.

Compliance and Status: All substitute parts maintain Active product status, RoHS3 compliance, and REACH unaffected designation, ensuring regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

1.5KE6V8CA (STMicroelectronics)

This substitute part is suitable for applications requiring higher peak pulse current handling (746A at 8/20µs pulse width) compared to the main part. The lower reverse standoff voltage (5.8V) and higher clamping voltage (13.4V) position this device for circuits with tighter voltage regulation requirements. The DO-201 package accommodates standard through-hole PCB layouts. Active product status and full RoHS3 compliance ensure long-term availability and regulatory alignment.

P6KE6V8CA (Taiwan Semiconductor Corporation)

This substitute part operates with reduced peak pulse current (57.1A) and power handling (600W), making it suitable for low-energy transient protection applications. The lower clamping voltage (10.5V) provides tighter voltage clamping compared to the main part. The DO-15 package is the smallest axial form factor among the three options, enabling space-constrained designs. Active product status and RoHS3 compliance are maintained.

Selection Basis

All substitute parts share identical bidirectional Zener diode topology, single-channel configuration, through-hole axial mounting, and regulatory compliance status. Selection between the main part and substitutes depends on specific application requirements for peak pulse current, power dissipation capacity, and package form factor constraints. No substitute part introduces regulatory or compliance risk.

Frequently Asked Questions (FAQ)

Q: Can the 1.5KE6V8CA replace the 5KP6.5CE3/TR13 in all applications?

A: The 1.5KE6V8CA is electrically compatible for general-purpose TVS applications. However, the lower peak pulse current (746A vs. 407A) and different pulse width specification (8/20µs vs. 10/1000µs) indicate different transient stress profiles. Application-specific transient energy levels determine compatibility. The DO-201 package requires PCB layout adjustment from the P600 package.

Q: What is the difference between the clamping voltages listed for each part?

A: Clamping voltage varies with peak pulse current and device geometry. The 5KP6.5CE3/TR13 clamps at 12.3V at 407A, the 1.5KE6V8CA clamps at 13.4V at 746A, and the P6KE6V8CA clamps at 10.5V at 57.1A. Lower clamping voltage at lower current indicates different internal resistance characteristics. Selection depends on the maximum allowable voltage in the protected circuit during transient events.

Q: Are the package differences between P600, DO-201, and DO-15 significant?

A: All three packages are through-hole axial configurations and are mechanically interchangeable in standard PCB designs. P600 and DO-201 are larger packages with higher current ratings. DO-15 is the smallest package and is suitable for space-constrained applications. PCB hole diameter and lead spacing must be verified for each package type during layout design.

Q: Do all substitute parts maintain the same operating temperature range?

A: The 5KP6.5CE3/TR13 specifies -55°C to 175°C operating temperature. The 1.5KE6V8CA and P6KE6V8CA do not provide explicit operating temperature specifications in the supplied data. Operating temperature range should be confirmed with manufacturer datasheets before final selection for temperature-critical applications.

Q: What is the significance of the different pulse width specifications (10/1000µs vs. 8/20µs)?

A: Pulse width specifications define the transient waveform used to characterize peak pulse current and power ratings. The 10/1000µs waveform (main part) represents a slower transient rise and fall, while the 8/20µs waveform (1.5KE6V8CA) represents a faster transient. These specifications reflect different application standards and do not affect functional substitution, but they indicate the transient environment for which each device is optimized.

Q: Are all parts RoHS3 compliant and suitable for regulated markets?

A: Yes. The 5KP6.5CE3/TR13, 1.5KE6V8CA, and P6KE6V8CA are all RoHS3 compliant and REACH unaffected. All parts carry Active product status, ensuring continued availability and regulatory support for current and future applications.
