5KP26E3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP26E3/TR13 is an active-status Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology. This unidirectional zener-type TVS diode is designed for general-purpose transient voltage protection in through-hole applications. The device features a 26V reverse standoff voltage, 46.6V maximum clamping voltage, and 107A peak pulse current capability with 5kW peak pulse power handling. The part is supplied in tape and reel packaging with P600 axial package configuration and is ROHS3 compliant with unlimited moisture sensitivity level. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and application continuity when the primary part number becomes unavailable or when alternative sourcing is required.

Substitute Part Grouping Explanation

Substitution of the 5KP26E3/TR13 is determined by alignment of critical electrical and mechanical parameters within the TVS diode category. The primary substitution criteria are:

Voltage Parameters: The reverse standoff voltage, breakdown voltage minimum, and clamping voltage maximum establish the protection threshold and response characteristics. Substitute parts must operate within compatible voltage ranges to ensure equivalent transient suppression performance.

Current and Power Handling: Peak pulse current (10/1000µs) and peak pulse power ratings define the device's ability to absorb transient energy. Substitutes must meet or exceed the application's current and power requirements.

Temperature Operating Range: The -55°C to 175°C junction temperature range must be maintained across substitute selections to ensure reliability across the full operating environment.

Mounting and Package Configuration: Through-hole mounting type and axial package geometry are mechanical requirements for circuit board integration. Substitute parts must be compatible with existing PCB layouts and assembly processes.

Compliance and Regulatory Status: ROHS3 compliance, REACH status, and moisture sensitivity level (MSL) ensure substitutes meet applicable regulatory and environmental standards.

The identified substitute part LCE28A from Littelfuse Inc. shares the same device type (unidirectional zener TVS), mounting method (through-hole), temperature range (-55°C to 175°C), and regulatory compliance (ROHS3, REACH Unaffected, MSL 1). Electrical parameters differ in standoff voltage (28V vs. 26V), clamping voltage (45.5V vs. 46.6V), and current/power ratings (33A, 1.5kW vs. 107A, 5kW), reflecting different protection profiles within the general-purpose TVS category.

Parameter Comparison

Engineering Selection Recommendations

Both the 5KP26E3/TR13 and LCE28A are active-status products with ROHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity level (MSL 1), confirming regulatory and environmental qualification for industrial applications.

Primary Selection (5KP26E3/TR13): Use when the application requires 107A peak pulse current and 5kW peak pulse power handling with 26V reverse standoff voltage and 46.6V clamping voltage. The P600 axial package provides the specified mechanical footprint.

Substitute Selection (LCE28A): Use when the application tolerates reduced peak pulse current (33A) and peak pulse power (1.5kW) with slightly elevated standoff voltage (28V) and comparable clamping voltage (45.5V). The DO-201AA axial package is mechanically compatible with through-hole PCB layouts. This substitute is suitable for lower-energy transient suppression requirements or when Littelfuse sourcing is preferred.

Selection between these parts is determined by the specific transient energy levels present in the application circuit and the mechanical package compatibility with existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can the LCE28A directly replace the 5KP26E3/TR13 in all applications?

A: Direct replacement depends on application transient energy requirements. The LCE28A has lower peak pulse current (33A vs. 107A) and power rating (1.5kW vs. 5kW). If the application generates transients exceeding 33A or 1.5kW, the LCE28A is not suitable. The higher standoff voltage (28V vs. 26V) may also affect protection threshold timing in sensitive circuits.

Q: Are the package configurations interchangeable?

A: Both parts use axial through-hole packages. The 5KP26E3/TR13 uses P600 package, while the LCE28A uses DO-201AA package. Both are axial configurations compatible with through-hole PCB assembly. Physical lead spacing and body dimensions should be verified against PCB layout requirements before substitution.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 5KP26E3/TR13 and LCE28A are ROHS3 compliant, REACH unaffected, and have MSL 1 (unlimited moisture sensitivity). Both are suitable for applications requiring these regulatory certifications.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -55°C to 175°C junction temperature range, ensuring equivalent thermal performance across the full operating environment.

Q: How do the voltage parameters differ between these parts?

A: The 5KP26E3/TR13 has 26V reverse standoff and 28.9V minimum breakdown voltage. The LCE28A has 28V reverse standoff and 31.1V minimum breakdown voltage. The clamping voltages are similar (46.6V vs. 45.5V). The higher standoff voltage of the LCE28A means it remains non-conducting at higher voltages before triggering protection.

Q: Which part should be selected for high-energy transient environments?

A: The 5KP26E3/TR13 is specified for high-energy transients due to its 107A peak pulse current and 5kW power rating. The LCE28A is suitable for lower-energy transient suppression applications.
