P6KE47A Equivalent & Substitute Parts

Part Overview

The P6KE47A is an active Transient Voltage Suppressor (TVS) diode manufactured by Taiwan Semiconductor Corporation, designed for general-purpose transient voltage protection applications. This unidirectional zener diode operates with a reverse standoff voltage of 40.2V and provides clamping protection at 64.8V with a peak pulse current rating of 9.3A. The component is packaged in DO-15 (DO-204AC) through-hole configuration and is ROHS3 compliant with unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching electrical performance parameters, mechanical compatibility, and regulatory compliance. Alternative sources provide identical or functionally equivalent protection characteristics for circuit design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6KE47A are qualified based on the following critical parameters that determine functional equivalence:

Electrical Performance Matching:

• Voltage - Reverse Standoff (Typ): 40.2V
• Voltage - Breakdown (Min): 44.7V
• Voltage - Clamping (Max) @ Ipp: 64.8V
• Current - Peak Pulse (10/1000µs): 9.3A (±0.1A tolerance acceptable)
• Power - Peak Pulse: 600W

Mechanical Compatibility:

• Mounting Type: Through Hole
• Package / Case: DO-204AC, DO-15, Axial (equivalent physical form factors)

Regulatory Compliance:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Parts meeting all electrical parameters and mechanical compatibility criteria are classified as direct substitutes. Variations in manufacturer series designation, packaging format (tape vs. bulk), or operating temperature range do not affect substitution eligibility when core electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed—P6KE47A (Taiwan Semiconductor), P6KE47A-E3/54 (Vishay), and TP6KE47A (Littelfuse)—are active products with ROHS3 compliance and REACH unaffected status, qualifying them for equivalent substitution in general-purpose transient voltage suppression applications.

P6KE47A-E3/54 (Vishay General Semiconductor) provides direct electrical and mechanical equivalence with specified operating temperature range of -55°C to 175°C (TJ). This part is supplied in cut tape packaging format.

TP6KE47A (Littelfuse) meets all electrical specifications with peak pulse current of 9.4A (within acceptable tolerance of the 9.3A specification) and includes automotive-grade qualification per AEC-Q101 standard. Operating temperature range is -55°C to 175°C (TJ). This part is supplied in cut tape packaging format and is suitable for applications requiring automotive-level reliability.

Selection between these substitutes depends on supply chain availability, packaging format requirements (cut tape vs. bulk), and application-specific qualification needs. All parts maintain identical voltage protection characteristics and mechanical compatibility with through-hole PCB mounting.

Frequently Asked Questions (FAQ)

Q: Can P6KE47A-E3/54 be used as a direct replacement for P6KE47A?

A: Yes. Both parts share identical electrical specifications: 40.2V reverse standoff voltage, 44.7V minimum breakdown voltage, 64.8V clamping voltage, and 9.3A peak pulse current. Both are packaged in DO-204AC (DO-15) through-hole configuration and are ROHS3 compliant. The primary difference is packaging format (cut tape vs. standard packaging) and specified operating temperature range for the Vishay part.

Q: Is TP6KE47A compatible with circuits designed for P6KE47A?

A: Yes. TP6KE47A meets all critical electrical parameters with 9.4A peak pulse current (0.1A above the 9.3A specification), maintaining functional equivalence. The part is packaged identically in DO-204AC (DO-15) through-hole configuration. The automotive-grade qualification (AEC-Q101) and specified operating temperature range (-55°C to 175°C) provide additional reliability assurance for demanding applications.

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 form factor. Both refer to a two-lead diode package with identical physical dimensions and PCB mounting characteristics. Parts specified as either DO-15 or DO-204AC are mechanically interchangeable.

Q: Are there operating temperature considerations when substituting parts?

A: The original P6KE47A does not specify an operating temperature range. Substitute parts P6KE47A-E3/54 and TP6KE47A both specify -55°C to 175°C (TJ) operating range. For applications operating within this temperature range, substitution is valid. Applications with temperature requirements outside this range require verification against the original part's undocumented specifications.

Q: Do all three parts have identical moisture sensitivity ratings?

A: Yes. All three parts—P6KE47A, P6KE47A-E3/54, and TP6KE47A—carry Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture-related handling restrictions during storage or assembly.

Q: What regulatory compliance applies to all substitute parts?

A: All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations. ECCN classification is EAR99 for all parts, and HTSUS code is 8541.10.0080.
