P4KE180A-B Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The P4KE180A-B is an active Zener-type Transient Voltage Suppressor diode manufactured by Littelfuse Inc., designed for general-purpose voltage transient protection applications. This through-hole component operates across a temperature range of -55°C to 175°C and is RoHS3 compliant. The part is currently in active production status with 1,107 units available in bulk packaging. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or packaging format preferences.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P4KE180A-B is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 154V
• Voltage - Breakdown (Min): 171V
• Voltage - Clamping (Max) @ Ipp: 246V
• Current - Peak Pulse (10/1000µs): 1.7A
• Power - Peak Pulse: 400W
• Operating Temperature Range: -55°C to 175°C
• Package / Case: DO-204AL (DO-41) axial through-hole
• Type: Zener, Unidirectional (1 channel)

The P4KE180A manufactured by Taiwan Semiconductor Corporation qualifies as a direct substitute. This part maintains identical electrical specifications and mechanical compatibility while differing only in packaging format (Tape & Reel versus Bulk) and manufacturer origin.

Parameter Comparison

Engineering Selection Recommendations

Both the P4KE180A-B (Littelfuse Inc.) and P4KE180A (Taiwan Semiconductor Corporation) are active production components with RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Packaging requirements: Bulk packaging is suitable for high-volume manufacturing or reel-fed assembly processes; Tape & Reel format is optimized for automated pick-and-place equipment.
• Inventory availability: The Littelfuse variant offers higher stock levels (1,107 units) compared to the Taiwan Semiconductor variant (641 units).
• Supply chain strategy: Either manufacturer may be selected based on established vendor relationships, lead time requirements, or cost considerations.

Both parts satisfy identical electrical and thermal performance criteria for general-purpose transient voltage suppression applications.

Frequently Asked Questions (FAQ)

Q: Can P4KE180A (Taiwan Semiconductor) be used as a direct replacement for P4KE180A-B (Littelfuse)?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, power dissipation, and operating temperature range. The primary difference is packaging format (Bulk versus Tape & Reel) and manufacturer.

Q: What is the significance of the "-B" suffix in P4KE180A-B?

A: The "-B" designation indicates the specific packaging format (Bulk) and manufacturer variant. The base part number P4KE180 defines the electrical specifications. Variants with different suffixes may indicate different packaging or manufacturer sources while maintaining the same core electrical performance.

Q: Are there any thermal or reliability differences between manufacturers?

A: Both parts operate across the identical temperature range (-55°C to 175°C) and share the same power dissipation rating (400W peak pulse). Reliability and thermal performance are equivalent based on the provided specifications.

Q: Which packaging format should be selected for automated assembly?

A: Tape & Reel (TR) packaging is standard for automated pick-and-place assembly equipment. Bulk packaging is typically used for manual assembly, kit distribution, or high-volume reel-fed processes with custom handling equipment.

Q: Are both parts compliant with environmental and trade regulations?

A: Yes. Both P4KE180A-B and P4KE180A are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.10.0080. Moisture sensitivity level is 1 (Unlimited) for both variants.
