30KPA160 Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The 30KPA160 is a unidirectional Zener-type transient voltage suppressor diode manufactured by Littelfuse, designed for general-purpose voltage clamping applications. This component features a 160V reverse standoff voltage rating with a maximum clamping voltage of 265.23V at peak pulse current, delivering 30kW peak pulse power dissipation capability in a through-hole P600 axial package.

The 30KPA160 is classified as obsolete. Identifying suitable substitute components is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 30KPA160 is determined by the following critical parameters:

• Reverse Standoff Voltage (Typ): Must equal 160V to maintain circuit protection thresholds
• Unidirectional Configuration: Must be single-channel Zener-type TVS diode
• Peak Pulse Current Rating: Must support minimum 120A (10/1000µs pulse)
• Peak Pulse Power Dissipation: Must support minimum 30kW
• Package Type: Must be P600 axial through-hole configuration for mechanical and electrical compatibility
• Operating Temperature Range: Must support -55°C to 175°C junction temperature
• Clamping Voltage Performance: Clamping voltage at Ipp must be within acceptable circuit design margins

The 30KPA160A meets all substitution criteria and is classified as an active product with equivalent electrical performance and identical mechanical packaging.

Parameter Comparison

Engineering Selection Recommendations

The 30KPA160A is a direct substitute for the obsolete 30KPA160. Both components share identical reverse standoff voltage, peak pulse current rating, peak pulse power dissipation, operating temperature range, and P600 axial package configuration. The 30KPA160A maintains ROHS3 compliance and is currently in active production status, ensuring long-term availability and supply chain continuity.

The 30KPA160A exhibits a lower maximum clamping voltage (252.6V versus 265.23V), which represents improved clamping performance and is acceptable for general-purpose transient voltage suppression applications where the original design margin accommodates this variation.

Frequently Asked Questions (FAQ)

Q: Can the 30KPA160A be used as a direct replacement for the 30KPA160?

A: Yes. Both components maintain identical reverse standoff voltage (160V), peak pulse current (120A), peak pulse power (30kW), operating temperature range (-55°C to 175°C), and P600 axial through-hole package configuration. The 30KPA160A is actively manufactured and available.

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

A: The 30KPA160A exhibits a maximum clamping voltage of 252.6V compared to the 30KPA160's 265.23V. This represents tighter clamping performance. Circuit designs that accommodate the original 265.23V specification will operate within acceptable margins with the improved 252.6V clamping characteristic.

Q: Are there any compliance or certification differences?

A: Both the 30KPA160 and 30KPA160A are ROHS3 compliant. The 30KPA160A includes REACH compliance information available upon request. Both components carry EAR99 ECCN classification and identical HTSUS codes.

Q: Does the package configuration remain identical?

A: Yes. Both components use the P600 axial through-hole package, ensuring mechanical and electrical compatibility in existing PCB designs without layout modifications.

Q: Why is the 30KPA160 classified as obsolete?

A: The 30KPA160 has been discontinued by Littelfuse. The 30KPA160A, manufactured by MDE Semiconductor Inc, provides equivalent electrical performance and is the recommended active alternative for new designs and component replenishment.
