5KP70CE3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP70CE3/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 a 70V reverse standoff voltage and provides 5kW peak pulse power dissipation in a through-hole P600 axial package. The component is ROHS3 compliant and carries an active product status. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and application requirements where alternative manufacturers or enhanced performance specifications are acceptable within the electrical and mechanical constraints of the 70V TVS diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP70CE3/TR13 are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 70V
• Package / Case: P600, Axial
• Mounting Type: Through Hole
• Type: Zener
• Bidirectional Channels: 1
• Applications: General Purpose

Allowable Variation Parameters:

• Voltage - Breakdown (Min): Range 77.8V to 78.2V
• Voltage - Clamping (Max) @ Ipp: Range 109V to 125V
• Current - Peak Pulse (10/1000µs): 40A to 278A
• Power - Peak Pulse: 5000W to 30000W
• Operating Temperature Range: -55°C to -50°C (minimum), 175°C (maximum)

Substitute parts maintain identical reverse standoff voltage and package specifications while permitting variations in clamping voltage, peak pulse current, and power dissipation ratings. These variations reflect different product series and manufacturers within the 70V TVS diode category, all suitable for general-purpose transient suppression applications.

Parameter Comparison

Engineering Selection Recommendations

5KP70CE3/TR13 (Microchip Technology) Primary selection for applications requiring ROHS3 compliance and Microchip Technology sourcing. Active product status with established supply chain. Suitable for standard 5kW transient suppression requirements.

15KPA70CA (MDE Semiconductor Inc) Substitute for applications requiring enhanced peak pulse current handling (132.9A) and 15kW power dissipation. ROHS3 compliant. Provides improved transient energy absorption compared to the primary part while maintaining identical reverse standoff voltage and package form factor. REACH status available upon request.

30KPA70CA (MDE Semiconductor Inc) Substitute for high-energy transient suppression applications requiring maximum peak pulse current (278A) and 30kW power dissipation. ROHS3 compliant. Delivers superior overvoltage protection capability within the same P600 axial package. REACH status available upon request.

5KP70CA (Diotec Semiconductor) Substitute offering equivalent 5kW power dissipation and similar peak pulse current (44A) to the primary part. Maintains P600 axial package compatibility. Operating temperature minimum of -50°C (versus -55°C for primary part). RoHS and REACH status not applicable; verify compliance requirements for specific applications.

All substitute parts maintain the critical 70V reverse standoff voltage specification and P600 through-hole axial package, ensuring mechanical and electrical compatibility within the 70V TVS diode category.

Frequently Asked Questions (FAQ)

Q: What determines whether a part can substitute for the 5KP70CE3/TR13?

A: Substitute parts must maintain the 70V reverse standoff voltage, P600 axial through-hole package, zener type, and single bidirectional channel configuration. Variations in clamping voltage, peak pulse current, and power dissipation are acceptable provided the application requirements are met.

Q: Can the 15KPA70CA or 30KPA70CA be used in place of the 5KP70CE3/TR13?

A: Yes. Both parts share identical reverse standoff voltage (70V) and package specifications (P600, axial, through-hole). The 15KPA70CA and 30KPA70CA provide higher peak pulse current and power dissipation ratings, making them suitable for applications experiencing higher transient energy levels. Lower clamping voltages (113.6V and 109V respectively) offer improved voltage regulation compared to the primary part's 125V maximum.

Q: What is the difference between the 5KP70CA (Diotec) and the 5KP70CE3/TR13 (Microchip)?

A: Both parts deliver identical 5kW peak pulse power and similar peak pulse current specifications. The primary differences are manufacturer (Diotec versus Microchip), operating temperature minimum (-50°C versus -55°C), and compliance certifications. The Diotec part does not carry ROHS3 compliance designation.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts use the P600 axial through-hole package. The 5KP70CE3/TR13 is supplied in Tape & Reel (TR) packaging, while the MDE Semiconductor parts (15KPA70CA, 30KPA70CA) are supplied in Bulk packaging. The Diotec 5KP70CA packaging format is not specified in available data.

Q: Which substitute part should be selected for maximum transient protection?

A: The 30KPA70CA provides the highest peak pulse current (278A) and power dissipation (30kW), delivering maximum transient energy absorption capability. Selection depends on application transient voltage and current specifications.

Q: Are all substitute parts ROHS3 compliant?

A: The 5KP70CE3/TR13, 15KPA70CA, and 30KPA70CA are ROHS3 compliant. The 5KP70CA (Diotec) carries "Not applicable" RoHS status. Verify compliance requirements for your specific application before selection.

Q: What is the impact of different clamping voltages among substitute parts?

A: Clamping voltage determines the maximum voltage level during transient suppression. The 5KP70CE3/TR13 clamps at 125V maximum, while the 15KPA70CA clamps at 113.6V and the 30KPA70CA at 109V. Lower clamping voltages provide tighter voltage regulation and better protection for sensitive downstream components.
