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

Part Overview

The P6KE200A is an active Transient Voltage Suppressor (TVS) diode designed for general-purpose overvoltage protection in through-hole applications. This unidirectional Zener diode operates with a reverse standoff voltage of 171V and provides clamping at 274V maximum, making it suitable for protecting sensitive electronic circuits from transient voltage spikes. The part is actively manufactured and widely available across multiple suppliers, with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Alternative models are necessary when specific packaging requirements, inventory constraints, or manufacturer preferences necessitate sourcing from different suppliers while maintaining identical electrical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6KE200A are qualified based on the following electrical and mechanical parameters:

Critical Matching 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

Allowable Variations:

• Manufacturer: Different suppliers provide equivalent parts under the same base product number (P6KE200)
• Packaging format: Cut Tape (CT) or standard packaging
• Operating Temperature Range: Minor variations within -55°C to -65°C lower bound are acceptable; upper bound fixed at 175°C
• Supplier Device Package designation: DO-15 or DO-204AC (DO-15) are equivalent

Parts that deviate from the critical matching parameters are excluded from direct substitution.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain identical electrical specifications for the critical parameters: reverse standoff voltage (171V), breakdown voltage (190V), clamping voltage (274V), peak pulse current (2.2A), and peak pulse power (600W). Selection among these equivalents should be based on the following factors:

Compliance & Certification: All substitute parts carry ROHS3 compliance and MSL 1 (unlimited) ratings where specified. The Vishay P6KE200A-E3/54 and Central Semiconductor P6KE200A TR PBFREE variants explicitly document these certifications. Fairchild Semiconductor P6KE200A does not specify compliance documentation in the provided data.

Operating Temperature Range: The Central Semiconductor P6KE200A TR PBFREE extends the lower operating temperature to -65°C, providing enhanced performance in colder environments compared to the standard -55°C minimum. The Fairchild variant operates from -50°C, which is the most restrictive lower bound. For applications requiring operation below -50°C, the Central Semiconductor or Diodes Incorporated variants are required.

Inventory Availability: Fairchild Semiconductor P6KE200A offers the highest inventory (165,300 pcs), followed by Vishay P6KE200A-E3/54 (65,300 pcs). These options provide supply chain stability for high-volume applications.

Packaging Format: All parts are available in DO-15 or DO-204AC (DO-15) equivalent packages suitable for through-hole PCB assembly. Packaging selection depends on specific board layout requirements and assembly equipment compatibility.

Frequently Asked Questions (FAQ)

Q: Can I substitute P6KE200A-E3/54 (Vishay) for P6KE200A-B (Diodes Incorporated)?

A: Yes. Both parts share identical electrical specifications: 171V reverse standoff, 190V breakdown, 274V clamping, 2.2A peak pulse current, and 600W peak pulse power. Both are Zener-type unidirectional TVS diodes in DO-15/DO-204AC packages. Operating temperature ranges differ slightly (-55°C to 175°C vs. -55°C to 175°C), but this does not affect substitution compatibility for standard applications.

Q: What is the difference between P6KE200A TR PBFREE and P6KE200A-TP?

A: Both parts are electrically equivalent with identical voltage and current ratings. The primary difference is the manufacturer: Central Semiconductor Corp (P6KE200A TR PBFREE) versus Micro Commercial Co (P6KE200A-TP). The Central Semiconductor variant specifies an extended lower operating temperature of -65°C compared to -55°C for the Micro Commercial variant. Both are packaged in Cut Tape (CT) format and carry ROHS3 compliance.

Q: Is the Fairchild P6KE200A suitable as a direct replacement?

A: Yes, the Fairchild P6KE200A maintains all critical electrical parameters. However, its operating temperature range begins at -50°C (versus -55°C for most alternatives), which may be a constraint in applications requiring operation below -50°C. Verify your application's minimum operating temperature requirement before selection.

Q: Why does P6KE200ARL appear in the substitute list but has different electrical specifications?

A: P6KE200ARL is not a direct substitute. This part exhibits different clamping voltage (353V vs. 274V) and peak pulse current (11.3A vs. 2.2A) specifications. It is excluded from the direct substitution group and should not be used as a replacement for P6KE200A applications.

Q: Are all substitute parts available in the same package?

A: Yes. All qualified substitute parts are available in DO-204AC, DO-15, and Axial package configurations. The supplier device package designation may vary (DO-15 or DO-204AC (DO-15)), but these are equivalent designations for the same physical package suitable for through-hole PCB assembly.

Q: What compliance certifications apply to all substitute parts?

A: All listed substitute parts carry ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings. REACH status is listed as REACH Unaffected for all parts. ECCN classification is EAR99 and HTSUS code is 8541.10.0080 across all variants.
