5KP100C-B Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The 5KP100C-B is a bidirectional Zener TVS diode manufactured by Littelfuse Inc., designed for general-purpose transient voltage suppression applications. This component features a 100V reverse standoff voltage rating and 5000W peak pulse power handling capability in a through-hole P600 axial package. The product is currently classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP100C-B is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 100V
• Bidirectional Channels: 1
• Power - Peak Pulse: 5000W (5kW)
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Operating Temperature Range: -55°C ~ 175°C (TJ)

Acceptable Variation Parameters:

• Voltage - Breakdown (Min): Range 104.85V to 111V
• Voltage - Clamping (Max) @ Ipp: Range 162V to 179V
• Current - Peak Pulse (10/1000µs): 27.9A to 31.5A

The substitute parts listed maintain identical standoff voltage, power rating, package configuration, and thermal operating range. Variations in breakdown voltage and clamping voltage remain within acceptable engineering tolerances for general-purpose transient suppression applications. All substitute parts are manufactured by Littelfuse Inc. or Microchip Technology and maintain active product status with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Littelfuse Inc., Active Status):

The 5KP100CA and 5KP100CA-B represent direct functional equivalents manufactured by the original equipment supplier. Both parts maintain identical electrical specifications within acceptable tolerances and are currently in active production status. The 5KP100CA is supplied in Cut Tape packaging, while the 5KP100CA-B is supplied in Bulk packaging. Selection between these two depends on procurement and assembly requirements.

Alternative Substitutes (Microchip Technology, Active Status, MFR Recommended):

The 5KP100CAE3/TR13 and 5KP100CE3/TR13 are manufacturer-recommended alternatives supplied by Microchip Technology in Tape & Reel packaging. Both maintain the 100V standoff voltage and 5000W power rating. The 5KP100CAE3/TR13 provides clamping voltage of 162V with 30.9A peak pulse current. The 5KP100CE3/TR13 provides higher clamping voltage of 179V with 27.9A peak pulse current. Selection between these alternatives depends on specific circuit clamping voltage requirements.

All substitute parts maintain ROHS3 compliance, identical thermal operating range, and through-hole P600 axial package configuration. Inventory availability is confirmed for all listed alternatives.

Frequently Asked Questions (FAQ)

Q: Can the 5KP100C-B be directly replaced with 5KP100CA or 5KP100CA-B?

A: Yes. Both parts maintain identical reverse standoff voltage (100V), power rating (5000W), package configuration (P600 axial), and thermal operating range (-55°C to 175°C). The primary difference is packaging format: 5KP100CA uses Cut Tape, while 5KP100CA-B uses Bulk packaging. Both are manufactured by Littelfuse Inc. and hold active product status.

Q: What is the difference between the Littelfuse and Microchip alternatives?

A: All alternatives maintain the same 100V standoff voltage and 5000W power rating. Littelfuse alternatives (5KP100CA, 5KP100CA-B) are supplied by the original manufacturer. Microchip alternatives (5KP100CAE3/TR13, 5KP100CE3/TR13) are manufacturer-recommended substitutes. The Microchip parts are supplied in Tape & Reel format and differ in clamping voltage specifications: 5KP100CAE3/TR13 at 162V and 5KP100CE3/TR13 at 179V.

Q: Are there differences in clamping voltage between substitute options?

A: Yes. The 5KP100C-B specifies 170.1V maximum clamping voltage. The 5KP100CA and 5KP100CA-B specify 162V. The 5KP100CAE3/TR13 specifies 162V. The 5KP100CE3/TR13 specifies 179V. All values remain within acceptable engineering tolerances for general-purpose transient suppression. Circuit-specific requirements determine the appropriate selection.

Q: What packaging options are available for substitutes?

A: The 5KP100CA is supplied in Cut Tape (CT) format. The 5KP100CA-B is supplied in Bulk format. The 5KP100CAE3/TR13 and 5KP100CE3/TR13 are supplied in Tape & Reel (TR) format. All maintain identical through-hole P600 axial package configuration for circuit board assembly.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). All maintain identical operating temperature range of -55°C to 175°C (TJ). All are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: Why is the 5KP100C-B classified as obsolete?

A: The 5KP100C-B has been discontinued by Littelfuse Inc. Active alternatives with identical electrical and mechanical specifications are available from both Littelfuse and Microchip Technology, ensuring continued system support and component availability.
