Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P4KE200 is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 171V
• Voltage - Breakdown (Min): 180V minimum
• Current - Peak Pulse (10/1000µs): 1.5A nominal
• Power - Peak Pulse: 400W
• Mounting Type: Through Hole
• Package / Case: DO-204AL, DO-41, Axial
• Type: Zener, Unidirectional (1 channel)
• Operating Temperature Range: -55°C to 175°C minimum

All identified substitute parts maintain these electrical specifications and physical form factors, enabling direct functional replacement in existing designs. Voltage clamping characteristics may vary within acceptable engineering tolerances (274V to 287.7V range) while preserving circuit protection performance.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are classified as active products, ensuring ongoing availability and manufacturing support. Selection among equivalents should prioritize the following factors:

Compliance & Certification: P4KE200AHE3/54 carries AEC-Q101 automotive qualification, suitable for applications requiring automotive-grade component reliability. All alternatives maintain ROHS3 compliance and REACH unaffected status, meeting environmental regulatory requirements.

Manufacturer Continuity: Vishay General Semiconductor variants (BZW04-171-E3/54, P4KE200A-E3/54, P4KE200AHE3/54) provide established supply chain stability through a major semiconductor manufacturer. Good-Ark Semiconductor P4KE200A offers high inventory availability (300,300 units). Micro Commercial Co variants (P4KE200A-AP, P4KE200A-BP, P4KE200A-TP) provide alternative sourcing with active product status.

Packaging Considerations: Vishay and Good-Ark parts maintain DO-204AL (DO-41) axial packaging identical to the original P4KE200. Micro Commercial Co and Comchip Technology variants are supplied in DO-41 form factor. Tape & Reel (TR) packaging from Vishay suits high-volume manufacturing; Cut Tape (CT) and Bulk options accommodate lower-volume requirements.

Temperature Range: P4KE200A-G operates to 150°C maximum junction temperature, compared to 175°C for all other alternatives. Applications requiring full -55°C to 175°C operation should exclude this variant.

Frequently Asked Questions (FAQ)

Q: Can P4KE200A directly replace the obsolete P4KE200?

A: Yes. P4KE200A maintains identical reverse standoff voltage (171V), peak pulse current (1.5A), and power rating (400W). Voltage clamping differs slightly (274V vs. 287.7V), remaining within acceptable protection margins for general-purpose applications. Both use DO-204AL (DO-41) through-hole packaging.

Q: What is the difference between Vishay BZW04-171-E3/54 and P4KE200A-E3/54?

A: Both are Vishay products with identical electrical specifications and operating temperature range (-55°C to 175°C). BZW04-171-E3/54 carries the TransZorb® series designation, while P4KE200A-E3/54 uses the P4KE base product number. Selection depends on design documentation requirements and supplier preference.

Q: Is P4KE200A-G suitable for all applications?

A: P4KE200A-G operates to 150°C maximum junction temperature, compared to 175°C for other alternatives. Applications with sustained high-temperature operation or thermal margin requirements should use alternatives with 175°C ratings. Peak pulse current is 1.46A versus 1.5A nominal, a negligible difference for most protection circuits.

Q: What packaging options are available?

A: Vishay variants supply Tape & Reel (TR) packaging for automated assembly. Good-Ark Semiconductor P4KE200A uses Cut Tape (CT). Micro Commercial Co offers Bulk packaging. All maintain DO-204AL or DO-41 axial through-hole form factors compatible with existing PCB layouts.

Q: Does P4KE200AHE3/54 require special handling for automotive applications?

A: P4KE200AHE3/54 carries AEC-Q101 automotive qualification, meeting automotive reliability standards. It maintains identical electrical performance to non-automotive variants. Use this part when design specifications explicitly require automotive-grade component certification.

Q: Are all substitutes ROHS3 compliant?

A: All listed alternatives maintain ROHS3 compliance and REACH unaffected status, meeting current environmental regulations. Compliance documentation is available from respective manufacturers.
