P6KE82C Equivalent & Substitute Parts

Part Overview

The P6KE82C is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component is classified as obsolete, necessitating identification of equivalent substitute parts that maintain electrical and mechanical compatibility. The P6KE82C operates as a bidirectional Zener diode in a through-hole DO-15 package, providing 600W peak pulse power dissipation capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6KE82C are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 70V to 70.1V
• Voltage - Clamping (Max) @ Ipp: 113V to 118.65V
• Power - Peak Pulse: 500W to 600W
• Bidirectional Channels: 1
• Mounting Type: Through Hole
• Package / Case: DO-15 or DO-204AC (equivalent designations)
• Type: Zener diode

Compliance Parameters:

• RoHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts maintain functional equivalence when all critical electrical parameters fall within the specified ranges and mechanical compatibility is preserved through identical or cross-compatible package designations.

Parameter Comparison

Engineering Selection Recommendations

P6KE82CA (Direct Substitute): This part is an active product from Taiwan Semiconductor Corporation with identical reverse standoff voltage (70.1V) and matching peak pulse power rating (600W). The clamping voltage is 5.65V lower (113V vs. 118.65V), which represents improved performance within acceptable tolerance margins for TVS applications. This part maintains full RoHS3 compliance and unlimited moisture sensitivity rating. Availability is significantly higher (16,750 pcs in stock vs. 1,006 pcs for the original).

SA70CA (Manufacturer Recommended Substitute): This part is designated as the manufacturer-recommended alternative, also from Taiwan Semiconductor Corporation. It maintains the 70V reverse standoff voltage specification and identical clamping voltage (113V). The peak pulse power rating is 500W, which is 100W lower than the original specification. This part is active, RoHS3 compliant, and includes specified operating temperature range (-55°C ~ 175°C). Inventory availability is moderate (1,051 pcs in stock).

Both substitute parts satisfy the critical electrical parameters for TVS diode substitution and maintain mechanical compatibility through DO-15 package equivalence. Selection between P6KE82CA and SA70CA depends on application power dissipation requirements and inventory availability constraints.

Frequently Asked Questions (FAQ)

Q: Can P6KE82CA be used as a direct replacement for P6KE82C?

A: Yes. Both parts maintain identical reverse standoff voltage (70.1V), identical peak pulse power rating (600W), and equivalent DO-15 package specifications. The clamping voltage difference (113V vs. 118.65V) represents improved performance characteristics within acceptable TVS diode tolerance ranges.

Q: What is the difference between P6KE82CA and SA70CA?

A: The primary difference is peak pulse power rating: P6KE82CA provides 600W while SA70CA provides 500W. Both maintain 70V reverse standoff voltage and 113V clamping voltage. SA70CA includes specified operating temperature range (-55°C ~ 175°C), while P6KE82CA does not specify this parameter in available documentation.

Q: Are the DO-15 and DO-204AC package designations interchangeable?

A: Yes. DO-15 and DO-204AC are equivalent package designations for axial through-hole diodes. Both substitute parts are compatible with applications designed for the original P6KE82C DO-15 package.

Q: Do all substitute parts meet RoHS3 compliance requirements?

A: Yes. Both P6KE82CA and SA70CA are RoHS3 compliant with MSL rating of 1 (Unlimited), matching the original P6KE82C specifications.

Q: Which substitute part should be selected for new designs?

A: Selection depends on application power dissipation requirements. For applications requiring 600W peak pulse power, P6KE82CA is appropriate. For applications with lower power requirements (≤500W), SA70CA is suitable and is the manufacturer-recommended alternative.
