5KP17A-TP Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The 5KP17A-TP is an active, ROHS3-compliant unidirectional Zener TVS diode manufactured by Micro Commercial Co, designed for general-purpose transient voltage suppression applications. This through-hole component features a 17V reverse standoff voltage with 27.6V maximum clamping voltage and 5000W peak pulse power rating. The part is currently in active production status with 1485 units in stock inventory.

Finding equivalent and substitute parts becomes necessary when the original component experiences supply constraints, when alternative packaging formats are required for manufacturing processes, or when design modifications call for different power dissipation or current handling characteristics within compatible electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP17A-TP is determined by the following critical electrical parameters:

• Voltage - Reverse Standoff (Typ): Must be 17V or within the 15.3V to 17.1V range to maintain circuit protection thresholds
• Voltage - Clamping (Max) @ Ipp: Must not exceed 29.3V to ensure adequate transient suppression
• Unidirectional Channels: Must equal 1 (single channel configuration)
• Type: Must be Zener TVS diode
• Mounting Type: Must be Through Hole
• Operating Temperature Range: Must support -55°C ~ 175°C minimum
• RoHS Status: Must be ROHS3 Compliant

The four substitute parts listed below meet these core electrical and compliance requirements. Variations in power dissipation (1500W to 15000W), peak pulse current (22A to 515.4A), and package format (R-6, DO-201, P600) represent acceptable design trade-offs based on application-specific requirements.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts maintain active product status and meet the core electrical requirements for TVS diode substitution. Selection between alternatives depends on application-specific power dissipation and current handling needs:

5KP17A (Littelfuse Inc.) provides electrical equivalence with identical voltage ratings (17V standoff, 27.6V clamping) and power dissipation (5000W). This part represents the closest functional match and differs only in package format (P600 vs. R-6) and manufacturer.

15KPA17A (MDE Semiconductor Inc) maintains matching voltage ratings while offering significantly higher power dissipation (15000W) and peak pulse current (515.4A). This part is suitable for applications requiring enhanced transient energy absorption.

1.5KE18A (Taiwan Semiconductor Corporation) operates within acceptable voltage parameters (15.3V standoff, 25.5V clamping) but provides reduced power dissipation (1500W) and peak pulse current (60A). This part is suitable for lower-energy transient suppression applications.

P6KE20A (Fairchild Semiconductor) operates within acceptable voltage parameters (17.1V standoff, 27.7V clamping) but provides reduced power dissipation (600W) and peak pulse current (22A). This part is suitable for minimal transient suppression requirements. Operating temperature range extends to -50°C minimum rather than -55°C.

All substitute parts carry ROHS3 compliance except P6KE20A, which does not specify RoHS status in the provided data.

Frequently Asked Questions (FAQ)

Q: Can the 1.5KE18A substitute for the 5KP17A-TP in all applications?

A: The 1.5KE18A operates within acceptable voltage parameters but provides only 1500W peak pulse power versus 5000W for the 5KP17A-TP. Substitution is valid only for applications where transient energy levels do not exceed 1500W. The lower reverse standoff voltage (15.3V vs. 17V) may affect circuit protection thresholds in sensitive applications.

Q: What is the primary difference between the 5KP17A-TP and the Littelfuse 5KP17A?

A: Both parts share identical electrical specifications (17V standoff, 27.6V clamping, 5000W power rating) and operating temperature range. The primary difference is manufacturer identity and package format designation (R-6 vs. P600). Both are ROHS3 compliant and active products.

Q: Is the 15KPA17A suitable as a direct replacement?

A: The 15KPA17A maintains matching voltage ratings (17V standoff, 18.99V breakdown minimum) and operates within acceptable clamping voltage (29.3V). However, it provides 15000W peak pulse power, which exceeds the 5KP17A-TP specification. This part is suitable for applications requiring higher transient energy absorption but may introduce unnecessary cost and board space considerations if the additional power rating is not required.

Q: Why does the P6KE20A have a different operating temperature minimum?

A: The P6KE20A specifies -50°C minimum operating temperature versus -55°C for the 5KP17A-TP. This represents a 5°C reduction in low-temperature performance. Substitution is valid only for applications where the operating environment does not require temperatures below -50°C.

Q: Are all substitute parts available in the same package format?

A: No. The 5KP17A-TP uses R-6 axial package. Substitute parts use alternative through-hole axial packages: 1.5KE18A (DO-201AA/DO-27), 15KPA17A (P600), 5KP17A Littelfuse (P600), and P6KE20A (DO-204AC/DO-15). Package format changes may require PCB layout modifications.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts except P6KE20A carry ROHS3 compliance certification. All parts carry EAR99 ECCN classification and HTSUS code 8541.10.0080. Moisture sensitivity level is 1 (Unlimited) for all parts where specified.
