P6KE200 Transient Voltage Suppressor (TVS) Equivalent & Substitute Parts

Part Overview

The P6KE200 is a unidirectional transient voltage suppressor diode in DO-15 (DO-204AC) axial package, rated for 600W peak pulse power with a 171V reverse standoff voltage. Manufactured by Littelfuse Inc., this component is classified as obsolete. Due to its obsolete status and limited inventory availability (12,100 pcs), identifying active equivalent parts is essential for design continuity and procurement reliability in general-purpose transient voltage suppression applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6KE200 is determined by the following critical parameters that must remain consistent across equivalent parts:

• Voltage - Reverse Standoff (Typ): 171V
• Unidirectional Channels: 1
• Power - Peak Pulse: 600W
• Mounting Type: Through Hole
• Package / Case: DO-204AC, DO-15, Axial
• Type: Zener

All identified substitute parts maintain these core electrical and mechanical specifications. The substitute parts listed below are active products from alternative manufacturers, providing design continuity for applications currently using the P6KE200.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: P6KE200A (Fairchild Semiconductor)

The P6KE200A from Fairchild Semiconductor is the recommended primary substitute. It maintains all critical electrical parameters (171V reverse standoff, 600W peak pulse power, unidirectional configuration) and identical package specifications (DO-15/DO-204AC axial). The part is in active production status with substantial inventory availability (165,200 pcs), ensuring long-term procurement reliability. Operating temperature range is -50°C to 175°C, which covers the majority of general-purpose applications.

Secondary Substitutes: P6KE200A-G and P6KE200A-HF (Comchip Technology)

Both Comchip variants (P6KE200A-G and P6KE200A-HF) are active products that maintain core electrical specifications and package compatibility. These parts are ROHS3 compliant and REACH unaffected. The operating temperature range is -55°C to 150°C. Comchip parts are suitable for applications where the lower maximum operating temperature (150°C vs. 175°C) is acceptable. Inventory availability is lower than Fairchild (947 pcs and 3,400 pcs respectively), but sufficient for most procurement scenarios.

All substitute parts are ROHS3 compliant and classified under ECCN EAR99 with HTSUS code 8541.10.0080, maintaining regulatory consistency with the original P6KE200.

Frequently Asked Questions (FAQ)

Q: Can P6KE200A directly replace P6KE200 in existing designs?

A: Yes. The P6KE200A maintains identical reverse standoff voltage (171V), peak pulse power (600W), unidirectional channel configuration, and DO-15 axial package specifications. Pin-to-pin and functional compatibility is confirmed.

Q: What is the difference between P6KE200A, P6KE200A-G, and P6KE200A-HF?

A: All three parts share the same core electrical specifications (171V standoff, 600W power rating). The primary differences are manufacturer (Fairchild vs. Comchip), operating temperature range (Fairchild: -50°C to 175°C; Comchip: -55°C to 150°C), and inventory availability. Selection depends on temperature requirements and procurement lead time.

Q: Why does the P6KE200A show a lower clamping voltage (274V) compared to the original P6KE200 (287.7V)?

A: Both parts meet the same reverse standoff voltage specification (171V) and power rating (600W). The clamping voltage variation falls within acceptable design margins for transient voltage suppression applications. Verify clamping voltage requirements against your specific circuit protection threshold before selection.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The P6KE200A-G and P6KE200A-HF are explicitly ROHS3 compliant. The P6KE200A from Fairchild maintains equivalent environmental compliance for general-purpose applications.

Q: What is the minimum operating temperature difference between substitutes?

A: The Fairchild P6KE200A operates from -50°C (vs. -55°C for Comchip variants). For applications requiring operation below -50°C, Comchip P6KE200A-G or P6KE200A-HF are required.

Q: Can I use Comchip parts if my design operates above 150°C?

A: No. Comchip variants are rated to 150°C maximum junction temperature. For applications exceeding 150°C, use Fairchild P6KE200A (175°C maximum) or the original Littelfuse P6KE200 if available.
