30KPA96C-B Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The 30KPA96C-B is a bidirectional Zener-type transient voltage suppressor diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component features a 96V reverse standoff voltage rating with a 163.8V maximum clamping voltage and 194.2A peak pulse current capability in a through-hole P600 axial package. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for continued system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 30KPA96C-B is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): Must equal 96V
• Current - Peak Pulse (10/1000µs): Must equal 194.2A
• Power - Peak Pulse: Must equal 30000W
• Operating Temperature Range: Must span -55°C to 175°C
• Mounting Type: Must be Through Hole
• Bidirectional Channels: Must equal 1
• Type: Must be Zener

The identified substitute parts maintain these core electrical specifications while offering active product status and improved availability. Variations in voltage breakdown minimum and clamping voltage maximum are permissible within the functional operating envelope of the application circuit, provided the reverse standoff voltage remains constant at 96V.

Parameter Comparison

Engineering Selection Recommendations

30KPA96CA-B (Littelfuse) is the primary substitute for the 30KPA96C-B. This part maintains identical electrical specifications, operates across the same temperature range, and is packaged in the P600 axial format. The component is manufactured by the original equipment supplier, carries active product status, and holds ROHS3 compliance with REACH Unaffected designation. This option provides direct mechanical and electrical compatibility with existing PCB layouts and assembly processes.

30KPA96CA (MDE Semiconductor Inc) offers equivalent electrical performance with active product status and ROHS3 compliance. The part shares the P600 axial package footprint and all critical electrical parameters. This alternative provides supply chain diversification while maintaining full functional compatibility.

30KP96CA-TP (Micro Commercial Co) is a manufacturer-recommended substitute with active product status. This part maintains all core electrical specifications and operates within the identical temperature envelope. The primary distinction is the R-6 axial package designation, which represents a mechanical variant of the through-hole axial form factor. Physical lead spacing and package dimensions should be verified against PCB design specifications prior to implementation, as the R-6 package may require layout adjustments compared to the P600 package.

Frequently Asked Questions (FAQ)

Q: Can the 30KPA96CA-B be used as a direct replacement for the 30KPA96C-B in existing designs?

A: Yes. The 30KPA96CA-B maintains identical reverse standoff voltage (96V), peak pulse current (194.2A), peak pulse power (30000W), operating temperature range (-55 to 175°C), and through-hole P600 axial package configuration. The component is electrically and mechanically compatible with existing PCB layouts.

Q: What is the difference between the P600 and R-6 package designations?

A: Both are through-hole axial package formats. The P600 and R-6 represent different package outline specifications. The 30KP96CA-TP uses the R-6 designation. Physical lead spacing, body diameter, and overall length may differ between these package types. PCB footprint compatibility must be confirmed before substitution.

Q: Are all substitute parts RoHS compliant?

A: The 30KPA96CA-B and 30KPA96CA are explicitly ROHS3 compliant. The 30KP96CA-TP RoHS status is not specified in the provided data. Compliance verification should be obtained from the manufacturer if RoHS certification is a design requirement.

Q: What is the significance of the voltage clamping difference between the main part and substitutes?

A: The 30KPA96C-B specifies a maximum clamping voltage of 163.8V, while the substitute parts specify 156V. Both values represent the maximum voltage at peak pulse current (Ipp). The lower clamping voltage in the substitutes indicates improved transient suppression performance. The 96V reverse standoff voltage remains constant across all parts, ensuring consistent circuit protection thresholds.

Q: Can I use the 30KPA96CA from MDE Semiconductor as an alternative to the Littelfuse options?

A: Yes. The 30KPA96CA maintains all critical electrical parameters and operates across the same temperature range. The part is manufactured by MDE Semiconductor Inc and carries active product status. Selection between Littelfuse and MDE Semiconductor options may be based on supply availability, lead time, or procurement preferences.
