5KP85CE3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP85CE3/TR13 is a transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This bidirectional Zener diode operates with an 85V reverse standoff voltage and provides peak pulse power dissipation of 5000W. The component is housed in a P600 axial through-hole package and is supplied on tape and reel (TR) for automated assembly.

The 5KP85CE3/TR13 maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified based on matching electrical performance parameters, mechanical compatibility, and compliance certifications to ensure functional equivalence in circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP85CE3/TR13 are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 85V
• Voltage - Breakdown (Min): 94.4V
• Power - Peak Pulse: 5000W
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Type: Zener
• Bidirectional Channels: 1
• Applications: General Purpose

Allowable Variation Parameters:

• Voltage - Clamping (Max) @ Ipp: Substitute parts may vary within the TVS diode performance envelope
• Current - Peak Pulse (10/1000µs): Substitute parts may exceed the main part specification
• Operating Temperature Range: Substitute parts must support the application temperature requirements

The 5KP85CA from Diotec Semiconductor qualifies as a substitute part based on matching reverse standoff voltage, breakdown voltage, peak pulse power rating, package type, and through-hole mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the 5KP85CE3/TR13 and 5KP85CA are Active product status components with ROHS3 compliance, confirming their suitability for current design implementations and regulatory requirements.

5KP85CE3/TR13 (Microchip Technology):

• Primary selection for applications requiring the specified clamping voltage of 151V maximum
• Operating temperature range extends to -55°C, supporting extended low-temperature environments
• Moisture Sensitivity Level 1 (Unlimited) provides maximum handling flexibility
• REACH Unaffected status confirms no substance of concern restrictions

5KP85CA (Diotec Semiconductor):

• Substitute selection offering lower clamping voltage of 137V maximum
• Higher peak pulse current capability of 36A compared to 33.1A
• Operating temperature range minimum of -50°C is suitable for most industrial applications
• Equivalent 5000W peak pulse power rating maintains protection performance
• Identical P600 axial package and through-hole mounting ensure direct mechanical compatibility

Selection between these parts depends on circuit-specific clamping voltage requirements and temperature operating envelope. Both parts satisfy the core TVS diode functional requirements for general-purpose transient voltage suppression.

Frequently Asked Questions (FAQ)

Q: Can the 5KP85CA substitute for the 5KP85CE3/TR13 in all applications?

A: The 5KP85CA qualifies as a substitute based on matching reverse standoff voltage (85V), breakdown voltage (94.4V), peak pulse power (5000W), and package type (P600 axial through-hole). However, the lower clamping voltage (137V vs. 151V) must be evaluated against circuit protection requirements. Applications with strict clamping voltage specifications may require the original 5KP85CE3/TR13.

Q: What is the difference in clamping voltage between these parts?

A: The 5KP85CE3/TR13 specifies a maximum clamping voltage of 151V at peak pulse current, while the 5KP85CA specifies 137V. This 14V difference affects the peak transient voltage seen by protected circuitry. Circuit designs with sensitive components may require the lower clamping voltage of the 5KP85CA or the original specification of the 5KP85CE3/TR13.

Q: Are both parts mechanically compatible?

A: Yes. Both parts use the P600 axial through-hole package and are supplied on tape and reel (TR) for automated assembly. Direct mechanical substitution is possible without PCB layout modifications.

Q: What is the temperature operating range difference?

A: The 5KP85CE3/TR13 operates from -55°C to 175°C, while the 5KP85CA operates from -50°C to 175°C. Applications requiring operation below -50°C require the 5KP85CE3/TR13.

Q: Do both parts meet current compliance requirements?

A: Yes. Both parts are ROHS3 compliant and maintain Active product status, confirming compliance with current environmental and regulatory standards.

Q: What is the peak pulse current difference?

A: The 5KP85CA provides 36A peak pulse current compared to 33.1A for the 5KP85CE3/TR13. The higher current capability of the 5KP85CA does not affect substitution suitability, as it represents improved performance within the same 5000W power rating.
