30KPA96-B Equivalent & Substitute Parts

Part Overview

The 30KPA96-B is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This unidirectional Zener diode features a 96V reverse standoff voltage with a 163.8V maximum clamping voltage and 194.2A peak pulse current capability in a through-hole P600 axial package. The part is currently listed as obsolete, necessitating identification of functionally equivalent alternatives from active product lines to maintain circuit protection performance in new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 30KPA96-B is determined by the following critical parameters:

• Voltage - Reverse Standoff: 96V (exact match required)
• Voltage - Breakdown (Min): 101.3V minimum
• Current - Peak Pulse (10/1000µs): 194.2A (exact match required)
• Power - Peak Pulse: 30000W (exact match required)
• Operating Temperature Range: -55°C to 175°C (exact match required)
• Type: Zener, Unidirectional
• Mounting Type: Through Hole
• Applications: General Purpose

The substitute parts identified maintain identical electrical performance specifications for voltage standoff, peak pulse current, and power dissipation. Variations in clamping voltage (156V to 163.8V) and breakdown voltage remain within acceptable tolerance ranges for general-purpose transient suppression. Package variations (P600 versus R-6) represent mechanical alternatives suitable for equivalent circuit board integration.

Parameter Comparison

Engineering Selection Recommendations

30KPA96A (MDE Semiconductor Inc) and 30KPA96A-B (Littelfuse Inc.) are direct functional equivalents to the obsolete 30KPA96-B. Both maintain identical P600 axial package geometry, electrical performance specifications, and operating temperature range. Both are ROHS3 compliant and active products with confirmed inventory availability. The 30KPA96A-B, manufactured by the original equipment supplier Littelfuse Inc., provides continuity with the original design source.

30KP96A-TP (Micro Commercial Co) is a manufacturer-recommended substitute with identical electrical specifications and active product status. The primary distinction is the R-6 axial package variant, which maintains equivalent through-hole mounting compatibility but differs in physical form factor. This option is suitable for applications where package geometry flexibility is acceptable.

All three substitute parts satisfy the electrical requirements for general-purpose transient voltage suppression with 96V standoff voltage, 194.2A peak pulse current, and 30kW peak power dissipation. Selection should prioritize product availability, supply chain continuity, and package compatibility with existing circuit board layouts.

Frequently Asked Questions (FAQ)

Q: Can 30KPA96A replace 30KPA96-B directly? A: Yes. The 30KPA96A maintains identical reverse standoff voltage (96V), peak pulse current (194.2A), power dissipation (30kW), operating temperature range (-55 to 175°C), and P600 axial package configuration. The lower clamping voltage (156V versus 163.8V) represents improved performance for transient suppression.

Q: What is the difference between 30KPA96A and 30KPA96A-B? A: Both parts are functionally equivalent with identical electrical specifications and P600 packaging. The primary difference is manufacturer: 30KPA96A is supplied by MDE Semiconductor Inc, while 30KPA96A-B is supplied by Littelfuse Inc. (the original manufacturer of the 30KPA96-B).

Q: Is 30KP96A-TP compatible with the original 30KPA96-B circuit design? A: Yes, with package consideration. The 30KP96A-TP provides identical electrical performance and through-hole mounting capability. The R-6 axial package differs physically from the P600 package but maintains equivalent lead spacing for standard through-hole circuit board integration.

Q: Are all substitute parts ROHS3 compliant? A: The 30KPA96A and 30KPA96A-B are confirmed ROHS3 compliant. RoHS compliance status for 30KP96A-TP is not specified in available documentation.

Q: What is the significance of the clamping voltage difference (163.8V versus 156V)? A: The lower clamping voltage in substitute parts (156V) indicates faster transient suppression response. Both values remain within acceptable operating parameters for general-purpose overvoltage protection. The 96V reverse standoff voltage and 194.2A peak pulse current remain identical across all parts.

Q: Can these parts be used interchangeably in production? A: Yes, provided package geometry compatibility is confirmed for your specific circuit board layout. The 30KPA96A and 30KPA96A-B use identical P600 packaging and are direct substitutes. The 30KP96A-TP uses R-6 packaging and requires verification of lead spacing compatibility with existing through-hole footprints.
