5KP11AE3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP11AE3/TR13 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This component features an 11V reverse standoff voltage with an 18.2V maximum clamping voltage and 275A peak pulse current capability. The device is housed in a P600 axial through-hole package and is supplied in Tape & Reel (TR) packaging format. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified based on matching electrical performance parameters and mechanical compatibility within the TVS diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP11AE3/TR13 are identified based on strict electrical and mechanical parameter matching within the TVS diode category. The substitution criteria are:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 11V
• Voltage - Breakdown (Min): 12.2V
• Voltage - Clamping (Max) @ Ipp: 18.2V
• Package / Case: P600, Axial (Through Hole)
• Type: Zener, Unidirectional
• Operating Temperature Range: -55°C to 175°C (TJ)
• RoHS3 Compliance Status

Allowable Variation Parameters:

• Current - Peak Pulse (10/1000µs): Within 5% tolerance of 275A
• Power - Peak Pulse: 5000W (5kW) rating maintained
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) formats are interchangeable for component selection purposes

The 5KP11A from Littelfuse Inc. qualifies as a substitute part based on identical voltage specifications, clamping characteristics, package type, and compliance certifications. Peak pulse current variation of 280.2A (versus 275A) falls within acceptable engineering tolerance for this device category.

Parameter Comparison

Engineering Selection Recommendations

The 5KP11A from Littelfuse Inc. is a direct electrical and mechanical substitute for the 5KP11AE3/TR13. Both components maintain identical voltage specifications, thermal operating ranges, and package configurations. The peak pulse current specification of 280.2A in the substitute part exceeds the original 275A rating, providing equivalent or superior performance in transient suppression applications.

Both parts carry Active product status and full RoHS3 compliance certification, ensuring regulatory alignment for current manufacturing and deployment standards. REACH compliance status is identical across both components. The primary distinction between the two parts is the packaging format: the original part is supplied in Tape & Reel format, while the substitute is available in Cut Tape format. This packaging difference does not affect electrical performance or mechanical compatibility in circuit applications.

Selection between these parts should be based on packaging availability, supplier inventory, and procurement requirements rather than electrical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can the 5KP11A replace the 5KP11AE3/TR13 in existing circuit designs?

A: Yes. The 5KP11A provides identical electrical performance across all critical parameters: reverse standoff voltage, breakdown voltage, clamping voltage, and operating temperature range. The P600 axial through-hole package is mechanically identical, allowing direct board-level substitution.

Q: What is the significance of the different peak pulse current ratings (275A vs. 280.2A)?

A: The 280.2A rating in the 5KP11A exceeds the 275A specification of the original part. This represents a performance enhancement rather than a limitation. Both parts are rated for 5000W peak pulse power, and the voltage clamping characteristics remain identical.

Q: Does the packaging format difference (Tape & Reel vs. Cut Tape) affect component performance?

A: No. Packaging format differences relate to supply and handling methods only. Tape & Reel and Cut Tape formats contain identical components with no electrical or mechanical performance variation. Format selection is determined by assembly equipment compatibility and procurement preferences.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 5KP11AE3/TR13 and 5KP11A maintain ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements for electronic component manufacturing and deployment.

Q: What parameters must remain identical for a valid TVS diode substitution?

A: For TVS diode substitution within this category, the following parameters must match: reverse standoff voltage, breakdown voltage, clamping voltage, package type, mounting configuration, and operating temperature range. Peak pulse current and power ratings may vary within acceptable engineering tolerance provided the substitute rating meets or exceeds the original specification.
