P6KE82CA-B Equivalent & Substitute Parts

Part Overview

The P6KE82CA-B is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This through-hole component operates with a reverse standoff voltage of 70.1V and provides clamping at 113V maximum, making it suitable for protecting sensitive electronic circuits from transient voltage events. The part is currently in active production status with 1,044 units available in bulk packaging. Alternative equivalent parts may be required due to packaging availability, lead time considerations, or specific supply chain requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P6KE82CA-B is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Requirements:

• Voltage - Reverse Standoff (Typ): 70.1V
• Voltage - Breakdown (Min): 77.9V
• Voltage - Clamping (Max) @ Ipp: 113V
• Current - Peak Pulse (10/1000µs): within acceptable tolerance
• Power - Peak Pulse: 600W
• Bidirectional Channels: 1
• Type: Zener

Mechanical Compatibility Requirements:

• Mounting Type: Through Hole
• Package / Case: DO-204AC, DO-15, or Axial equivalent
• Operating Temperature Range: -55°C ~ 175°C (TJ) or equivalent

Compliance Requirements:

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

The P6KE82CA part from Taiwan Semiconductor Corporation meets all electrical and mechanical substitution criteria, with the primary difference being packaging format (Tape & Reel versus Bulk) and a marginally lower peak pulse current specification (5.3A versus 5.4A).

Parameter Comparison

Engineering Selection Recommendations

Both the P6KE82CA-B and P6KE82CA are active production components with ROHS3 compliance and unlimited moisture sensitivity ratings, making them suitable for equivalent substitution in general-purpose transient voltage suppression applications. The P6KE82CA from Taiwan Semiconductor Corporation maintains electrical parity across all critical voltage parameters and offers significantly higher inventory availability in Tape & Reel packaging format. The marginal difference in peak pulse current (5.3A versus 5.4A) remains within the 600W power dissipation envelope for both devices. Selection between these parts should be based on packaging requirements, supply chain lead times, and inventory availability rather than electrical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can the P6KE82CA substitute for the P6KE82CA-B in all applications?

A: Yes, provided the application does not require the specific bulk packaging format of the P6KE82CA-B. Both parts share identical electrical specifications for voltage standoff, breakdown, and clamping characteristics. The primary difference is packaging format (Tape & Reel versus Bulk) and a 0.1A variance in peak pulse current, which does not affect the 600W power dissipation rating.

Q: What is the significance of the DO-204AC and DO-15 package designations?

A: DO-204AC and DO-15 are equivalent designations for the same axial through-hole package format used in this TVS diode series. Both the main part and substitute maintain compatibility with this package standard, ensuring mechanical interchangeability in PCB designs.

Q: Are there compliance differences between the two parts?

A: No. Both the P6KE82CA-B and P6KE82CA maintain identical ROHS3 compliance status, unlimited moisture sensitivity level (MSL 1), and equivalent REACH and ECCN classifications. Both are suitable for applications requiring regulatory compliance in these areas.

Q: Why is the peak pulse current specification different between the two parts?

A: The P6KE82CA specifies 5.3A peak pulse current compared to 5.4A for the P6KE82CA-B. This 0.1A difference does not affect the maximum power dissipation rating of 600W for either device and remains within acceptable tolerance for general-purpose transient voltage suppression applications.

Q: What factors should determine part selection between these two options?

A: Selection should be based on packaging format requirements (Bulk versus Tape & Reel), supply chain availability, lead time considerations, and inventory levels. The P6KE82CA offers significantly higher stock availability (16,750 units) compared to the P6KE82CA-B (1,044 units), making it preferable for high-volume procurement scenarios.
