MP6KE82CAE3 Equivalent & Substitute Parts

Part Overview

The MP6KE82CAE3 is an active Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This bidirectional Zener-type TVS diode operates with a reverse standoff voltage of 70.1V and provides clamping at 113V maximum, with a peak pulse current rating of 5.3A and peak pulse power of 600W. The device is packaged in a T-18 axial through-hole configuration and meets MIL-PRF-19500 military qualification standards.

Equivalent and substitute parts are necessary when the original MP6KE82CAE3 becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when compliance requirements differ between applications. Substitute parts must maintain identical electrical performance parameters while potentially offering different packaging, availability, or compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MP6KE82CAE3 is determined by strict equivalence of the following electrical and mechanical parameters:

Critical Electrical Parameters (Must Match):

• Voltage - Reverse Standoff (Typ): 70.1V
• Voltage - Breakdown (Min): 77.9V
• Voltage - Clamping (Max) @ Ipp: 113V
• Current - Peak Pulse (10/1000µs): 5.3A
• Power - Peak Pulse: 600W
• Bidirectional Channels: 1
• Type: Zener

Mechanical Parameters (May Vary):

• Package / Case format (T-18 vs. DO-15)
• Packaging type (Bulk vs. Tape & Reel)

Compliance Parameters (May Vary):

• RoHS status
• Operating temperature range specifications
• Manufacturer and supplier

The P6KE82CA manufactured by Taiwan Semiconductor Corporation qualifies as a direct electrical substitute, sharing the identical base product number (P6KE82) and all critical electrical parameters. The primary difference is the package format: P6KE82CA uses DO-15 (DO-204AC) axial packaging instead of T-18, and is supplied in Tape & Reel format with RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

MP6KE82CAE3 (Microchip Technology):

• Primary selection for applications requiring MIL-PRF-19500 military qualification
• Suitable for military-grade or aerospace applications where military certification is mandatory
• T-18 axial package format for through-hole PCB assembly
• RoHS non-compliant status requires verification against application environmental requirements
• Bulk packaging format appropriate for high-volume manufacturing or component stocking

P6KE82CA (Taiwan Semiconductor Corporation):

• Direct electrical equivalent with identical performance parameters
• RoHS3 compliance suitable for applications with environmental or regulatory compliance requirements
• DO-15 package format compatible with standard through-hole PCB assembly processes
• Tape & Reel packaging format optimized for automated assembly and pick-and-place equipment
• Higher inventory availability (16,750 pcs vs. 910 pcs) supports shorter lead times
• Appropriate for commercial and industrial applications where military qualification is not required

Both parts share identical electrical specifications and are suitable for general-purpose transient voltage suppression applications. Selection between them depends on packaging format requirements, compliance certifications, and manufacturing process compatibility.

Frequently Asked Questions (FAQ)

Q: Can P6KE82CA be used as a direct replacement for MP6KE82CAE3 in the same circuit?

A: Yes. Both devices have identical electrical parameters: 70.1V reverse standoff voltage, 77.9V minimum breakdown voltage, 113V maximum clamping voltage, 5.3A peak pulse current, and 600W peak pulse power. The electrical performance in circuit operation is equivalent.

Q: What is the difference between T-18 and DO-15 package formats?

A: Both are axial through-hole packages for PCB mounting. T-18 and DO-15 (DO-204AC) are different physical package designations. The choice between them depends on PCB footprint design, assembly equipment compatibility, and manufacturing process specifications. Verify PCB layout and assembly equipment compatibility before substitution.

Q: Does the RoHS compliance difference affect substitution?

A: RoHS compliance status depends on application requirements. MP6KE82CAE3 is RoHS non-compliant; P6KE82CA is RoHS3 compliant. Applications subject to RoHS regulations (EU Directive 2011/65/EU or equivalent) require the RoHS3-compliant P6KE82CA. Applications without RoHS requirements can use either part.

Q: Why is P6KE82CA available in higher quantities?

A: Inventory levels reflect current market demand and supplier stocking practices. Higher availability of P6KE82CA (16,750 pcs) compared to MP6KE82CAE3 (910 pcs) may indicate broader commercial market adoption or different distribution channels. Verify current availability with suppliers for specific procurement timelines.

Q: Are there operating temperature differences between the two parts?

A: MP6KE82CAE3 specifies operating temperature range of -65°C to 150°C (TJ). P6KE82CA does not provide operating temperature specifications in the available data. For applications with specific temperature requirements, verify P6KE82CA temperature specifications with the manufacturer before substitution.

Q: What is the significance of the base product number P6KE82?

A: The base product number P6KE82 indicates the core electrical specification: 82V series TVS diode. Both MP6KE82CAE3 and P6KE82CA share this base designation, confirming they are designed to the same electrical specification. Suffix variations (CAE3, CA) indicate manufacturer, package, and compliance differences.

Q: Can these parts be used interchangeably in military applications?

A: MP6KE82CAE3 carries MIL-PRF-19500 military qualification. P6KE82CA does not list military qualification. Military applications requiring MIL-PRF-19500 certification must use MP6KE82CAE3. For non-military applications, P6KE82CA is electrically equivalent.

Q: What packaging format should be selected for automated assembly?

A: P6KE82CA supplied in Tape & Reel (TR) format is optimized for automated pick-and-place assembly equipment. MP6KE82CAE3 supplied in Bulk format is suitable for manual assembly or high-volume stocking. Verify assembly equipment compatibility with selected packaging format.
