30KPA96 Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The 30KPA96 is a unidirectional 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 with a maximum clamping voltage of 163.8V at peak pulse current, housed in a P600 axial through-hole package. The 30KPA96 is classified as obsolete, making identification of functionally equivalent active alternatives essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 30KPA96 is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 96V
• Current - Peak Pulse (10/1000µs): 194.2A
• Power - Peak Pulse: 30000W
• Package / Case: P600, Axial (Through Hole)
• Type: Zener, Unidirectional (1 channel)
• Operating Temperature Range: -55°C to 175°C (TJ)

The 30KPA96A qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Variations in voltage breakdown and clamping specifications remain within acceptable tolerance ranges for the same functional class and application category.

Engineering Selection Recommendations

The 30KPA96A (MDE Semiconductor Inc.) is a direct functional equivalent to the obsolete 30KPA96. Selection between these parts should be based on the following criteria:

• The 30KPA96A carries Active product status, ensuring continued availability and manufacturing support, whereas the 30KPA96 is obsolete.
• Both components maintain ROHS3 compliance and equivalent electrical performance within specified tolerance ranges.
• The 30KPA96A is available in bulk packaging with 2048 units in stock, compared to 885 units of the original part.
• Identical mechanical compatibility: both use P600 axial through-hole packaging, permitting direct board-level substitution without layout modification.
• Voltage clamping performance of the 30KPA96A (156V) is superior to the original specification (163.8V), providing enhanced transient suppression characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 30KPA96A be used as a direct replacement for the 30KPA96 on existing circuit boards?

A: Yes. Both components share identical P600 axial through-hole packaging and mounting footprint. No PCB layout changes are required for substitution.

Q: What is the significance of the voltage clamping difference between the two parts?

A: The 30KPA96A exhibits a lower maximum clamping voltage (156V vs. 163.8V). This represents improved transient suppression performance and remains within acceptable tolerance for the 96V standoff voltage class. Both parts are rated for identical peak pulse current (194.2A) and power dissipation (30kW).

Q: Why is the 30KPA96 listed as obsolete?

A: Obsolescence indicates the part is no longer in active production. The 30KPA96A provides equivalent functionality with active manufacturing status, ensuring long-term supply chain reliability.

Q: Are there compliance differences between the two parts?

A: Both components are ROHS3 compliant. The 30KPA96A includes REACH compliance information available upon request, providing additional regulatory documentation for applications requiring extended compliance verification.

Q: What packaging options are available for the 30KPA96A?

A: The 30KPA96A is supplied in bulk packaging. The original 30KPA96 packaging specification was not provided in the technical data.
