5KP22CE3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP22CE3/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 22V reverse standoff voltage and provides peak pulse power dissipation of 5000W. The component is supplied in Tape & Reel packaging with Through Hole P600 axial mounting. The part maintains Active product status and is fully RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified to provide design flexibility when the primary part is unavailable, when alternative packaging formats are required, or when enhanced performance characteristics are beneficial for specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP22CE3/TR13 are qualified based on the following critical parameters that determine functional equivalence:

Voltage Parameters: All substitute parts maintain the same 22V reverse standoff voltage specification, ensuring identical circuit protection thresholds. Breakdown voltage minimums and clamping voltage maximums remain within acceptable tolerance ranges for general-purpose TVS applications.

Current and Power Ratings: Substitute parts are grouped into two categories based on peak pulse current and power dissipation capacity. The 5KP22CA maintains identical 5000W peak pulse power with comparable 143.7A peak pulse current. The 15KPA22CA provides enhanced performance with 15000W peak pulse power and 407A peak pulse current, suitable for applications requiring higher transient energy absorption.

Package and Mounting: All substitute parts utilize the P600 axial Through Hole package, ensuring mechanical and electrical compatibility with existing PCB designs and assembly processes.

Compliance and Environmental: All substitute parts are RoHS3 compliant with MSL 1 rating and operate across the identical -55°C to 175°C temperature range, maintaining regulatory and environmental consistency.

Packaging Format: The primary part is supplied in Tape & Reel format. Substitute parts are available in Bulk and Cut Tape formats, providing alternative procurement and handling options.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (5KP22CA - Littelfuse Inc.): The 5KP22CA is the primary substitute for the 5KP22CE3/TR13. Both parts share identical 22V reverse standoff voltage, 5000W peak pulse power rating, and P600 axial Through Hole package. The 5KP22CA exhibits lower clamping voltage (35.5V versus 39.4V) and slightly higher peak pulse current (143.7A versus 127A), providing marginally improved transient suppression characteristics. All compliance certifications, temperature ratings, and environmental specifications are equivalent. The Cut Tape packaging format offers alternative procurement flexibility compared to Tape & Reel.

Enhanced Performance Alternative (15KPA22CA - MDE Semiconductor Inc.): The 15KPA22CA maintains the same 22V reverse standoff voltage and P600 axial package but provides significantly enhanced transient energy absorption with 15000W peak pulse power and 407A peak pulse current. This part is suitable for applications requiring higher transient stress tolerance or where circuit protection margins must be increased. The clamping voltage (37.1V) remains within acceptable operating parameters. All regulatory and environmental specifications remain consistent with the primary part.

Compliance Verification: All three parts maintain Active product status, RoHS3 compliance, MSL 1 rating, and -55°C to 175°C operating temperature range. Selection between these parts is determined by application-specific transient energy requirements and packaging procurement preferences rather than regulatory or environmental constraints.

Frequently Asked Questions (FAQ)

Q: Can the 5KP22CA directly replace the 5KP22CE3/TR13 in existing designs?

A: Yes. Both parts share identical voltage specifications (22V reverse standoff), power rating (5000W peak pulse), and P600 axial Through Hole package. The 5KP22CA exhibits lower clamping voltage and higher peak pulse current, providing equivalent or improved protection performance. The primary difference is packaging format: the original part uses Tape & Reel while the substitute uses Cut Tape.

Q: What is the functional difference between the 5KP22CA and 15KPA22CA?

A: Both parts maintain the same 22V reverse standoff voltage and P600 axial package. The 15KPA22CA provides three times the peak pulse power (15000W versus 5000W) and significantly higher peak pulse current (407A versus 143.7A). The 15KPA22CA is selected for applications requiring enhanced transient energy absorption or higher circuit protection margins.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The 5KP22CE3/TR13, 5KP22CA, and 15KPA22CA are all RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. All parts meet identical environmental and regulatory requirements.

Q: What is the significance of the P600 package designation?

A: P600 designates an axial Through Hole package format used for radial lead component mounting on printed circuit boards. All three parts utilize this identical package, ensuring mechanical and electrical compatibility with existing PCB designs and assembly processes.

Q: How do clamping voltage differences affect circuit protection?

A: Clamping voltage determines the maximum voltage level the TVS diode allows across the protected circuit during transient events. The 5KP22CE3/TR13 clamps at 39.4V maximum, while the 5KP22CA clamps at 35.5V and the 15KPA22CA at 37.1V. Lower clamping voltages provide tighter protection margins. All values remain within acceptable ranges for general-purpose TVS applications with 22V standoff specifications.

Q: Does packaging format (Tape & Reel versus Cut Tape versus Bulk) affect electrical performance?

A: No. Packaging format affects only procurement, handling, and assembly processes. Electrical and thermal performance characteristics are identical regardless of packaging format. Selection between Tape & Reel, Cut Tape, and Bulk formats is determined by manufacturing requirements and inventory management preferences.

Q: What operating temperature range applies to all substitute parts?

A: All parts operate across the identical -55°C to 175°C junction temperature range, ensuring thermal performance consistency across all substitute options.
