P6KE200A Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The P6KE200A is a unidirectional Zener-type transient voltage suppressor diode designed for general-purpose overvoltage protection applications. Manufactured in DO-15 (DO-204AC) axial through-hole package, this component provides 274V clamping voltage at 2.2A peak pulse current with 600W peak pulse power dissipation capability.

The original manufacturer part P6KE200A-T (Diodes Incorporated) carries an Obsolete product status. Equivalent and substitute parts from active manufacturers are available to maintain design continuity and ensure supply chain reliability for new production and field replacements.

Substitute Part Grouping Explanation

Substitution eligibility for P6KE200A TVS diodes is determined by strict equivalence across the following critical parameters:

Voltage - Reverse Standoff (Typ): 171V
Voltage - Breakdown (Min): 190V
Voltage - Clamping (Max) @ Ipp: 274V
Current - Peak Pulse (10/1000µs): 2.2A
Power - Peak Pulse: 600W
Type: Zener
Unidirectional Channels: 1
Mounting Type: Through Hole
Package / Case: DO-204AC, DO-15, Axial

All substitute parts listed maintain identical electrical performance specifications. Packaging variants (Cut Tape, Bulk, Tape & Box, Tape & Reel) and manufacturer differences do not affect electrical equivalence. Operating temperature ranges may vary slightly between manufacturers; verify application requirements against specific part specifications.

Engineering Selection Recommendations

All listed substitute parts maintain electrical equivalence to the obsolete P6KE200A-T. Selection among active alternatives should be based on the following criteria:

Product Status & Availability: All substitute parts carry Active product status, ensuring continued manufacturing and supply chain support. The original P6KE200A-T (Obsolete) should be replaced with an active equivalent for new designs and production.

Compliance & Certifications: Parts from Littelfuse Inc., Vishay General Semiconductor, and Central Semiconductor Corp carry ROHS3 Compliant certification. Parts from Micro Commercial Co do not specify RoHS status in provided data; verify compliance requirements for your application before selection.

Automotive Grade Consideration: P6KE200AHE3/54 (Vishay) carries AEC-Q101 automotive qualification and Automotive Grade designation. Select this part for automotive or high-reliability applications requiring formal qualification documentation.

Operating Temperature Range: Central Semiconductor Corp P6KE200A TR PBFREE extends the lower operating temperature to -65°C compared to -55°C for most alternatives. Select this part if extended low-temperature operation is required.

Packaging Format: Choose packaging based on procurement and assembly requirements: Cut Tape (CT) for automated pick-and-place assembly, Bulk for manual assembly or reel consolidation, Tape & Box (TB) for mixed-volume orders, or Tape & Reel (TR) for high-volume automated production.

Frequently Asked Questions (FAQ)

Q: Can I substitute P6KE200A-T with any of the listed parts?

A: Yes. All listed parts maintain identical electrical specifications (171V standoff, 190V breakdown, 274V clamping, 2.2A peak pulse, 600W peak power) and are mechanically compatible in DO-15 (DO-204AC) through-hole applications. Verify packaging format and compliance certifications match your procurement requirements.

Q: What is the difference between DO-15 and DO-204AC packaging?

A: DO-15 and DO-204AC are equivalent designations for the same axial through-hole package. Both refer to a two-lead cylindrical component with axial leads suitable for through-hole PCB mounting. No physical or electrical difference exists between parts labeled with either designation.

Q: Does operating temperature range affect substitution eligibility?

A: Operating temperature range does not disqualify substitution if your application operates within the specified range of the substitute part. Most parts specify -55°C to 175°C; Central Semiconductor Corp extends to -65°C. Verify your application's temperature requirements fall within the selected part's range.

Q: Are there differences between manufacturers in electrical performance?

A: No. All substitute parts meet identical electrical specifications for voltage, current, and power parameters. Manufacturer differences relate to packaging format, compliance certifications, and supply chain availability, not electrical performance.

Q: What does ROHS3 Compliant mean for this component?

A: ROHS3 Compliant indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. Verify your application or regional requirements mandate RoHS compliance before selecting parts without this certification.

Q: Is AEC-Q101 qualification necessary for my application?

A: AEC-Q101 qualification is required only for automotive applications or designs subject to automotive quality standards. P6KE200AHE3/54 carries this qualification. For general-purpose, industrial, or consumer applications, AEC-Q101 is not necessary.

Q: Can I mix different manufacturers' parts in the same design?

A: Yes. All substitute parts are electrically equivalent and mechanically compatible. Mixing manufacturers is acceptable from a technical standpoint; however, verify procurement, traceability, and compliance documentation requirements for your specific application or industry standards.
