5KP9.0CE3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP9.0CE3/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 9V reverse standoff voltage and provides peak pulse current handling of 296A at a clamping voltage of 16.9V maximum. The component is housed in a P600 axial through-hole package and is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part number becomes unavailable or when alternative sourcing is required for cost optimization or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP9.0CE3/TR13 are identified based on electrical and mechanical compatibility within the transient voltage suppressor category. The substitution logic is based on the following critical parameters:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff (Typ): 9V
• Voltage - Breakdown (Min): 10V
• Operating Temperature Range: -55°C to 175°C (TJ)
• Type: Zener, Bidirectional
• Applications: General Purpose

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package Category: Axial

The SA9.0CA manufactured by Taiwan Semiconductor Corporation meets these core compatibility requirements. Both parts share identical reverse standoff voltage (9V), breakdown voltage (10V), operating temperature range, and through-hole axial mounting configuration. Differences in clamping voltage (16.9V vs. 15.4V) and peak pulse current (296A vs. 34A) reflect different power handling capabilities within the same voltage class, making the SA9.0CA suitable for applications with lower transient energy requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (5KP9.0CE3/TR13): The 5KP9.0CE3/TR13 is the specified component for applications requiring 296A peak pulse current handling and 5kW peak pulse power dissipation. This part is in active production status with full ROHS3 compliance and unlimited moisture sensitivity rating. Selection of this part is appropriate for high-energy transient suppression in general-purpose applications.

Substitute Part (SA9.0CA): The SA9.0CA is suitable as a substitute when the application transient energy profile is lower, specifically where peak pulse current does not exceed 34A and peak pulse power dissipation is limited to 500W. Both parts maintain identical voltage specifications (9V reverse standoff, 10V breakdown minimum) and operating temperature range (-55°C to 175°C). The SA9.0CA is in active production status with ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory equivalence.

Package Consideration: The primary part uses P600 axial packaging, while the substitute uses DO-204AC (DO-15) axial packaging. Both are through-hole axial configurations suitable for printed circuit board mounting. Physical dimensions and lead spacing differ between packages and must be verified for board layout compatibility.

Compliance Status: Both parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification, ensuring equivalent regulatory standing for procurement and deployment.

Frequently Asked Questions (FAQ)

Q: Can the SA9.0CA directly replace the 5KP9.0CE3/TR13 in all applications?

A: The SA9.0CA is electrically compatible for voltage specifications (9V reverse standoff, 10V breakdown) and operating temperature range. However, the SA9.0CA has reduced peak pulse current (34A vs. 296A) and peak pulse power (500W vs. 5000W). Substitution is valid only when the application transient energy does not exceed the SA9.0CA ratings. Circuit analysis must confirm that peak pulse current and power dissipation remain within SA9.0CA limits.

Q: Are there package compatibility issues between P600 and DO-204AC (DO-15)?

A: Both packages are through-hole axial configurations with different physical dimensions and lead spacing. The P600 package is larger and accommodates higher power dissipation. DO-204AC (DO-15) is a smaller package. PCB layout modifications may be required to accommodate the different package footprint. Lead spacing and hole diameter compatibility must be verified before substitution.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 5KP9.0CE3/TR13 and SA9.0CA are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Moisture sensitivity level is 1 (unlimited) for both parts, indicating no special handling requirements during storage or assembly.

Q: What is the primary difference between these two TVS diodes?

A: The primary difference is power handling capacity. The 5KP9.0CE3/TR13 handles 296A peak pulse current and 5kW peak pulse power, while the SA9.0CA handles 34A peak pulse current and 500W peak pulse power. Both maintain the same voltage protection characteristics (9V standoff, 10V breakdown). Selection depends on the magnitude of transient energy in the protected circuit.

Q: Can I use the 5KP9.0CE3/TR13 in place of the SA9.0CA?

A: Yes. The 5KP9.0CE3/TR13 provides higher power handling capacity and is electrically compatible with the same voltage specifications. However, the larger P600 package may not fit in PCB layouts designed for the smaller DO-204AC (DO-15) package. Physical footprint verification is required.

Q: What inventory status should I consider for procurement?

A: The 5KP9.0CE3/TR13 has 834 pieces in stock, while the SA9.0CA has 8300 pieces in stock. Both parts are in active production status. Availability and lead time should be evaluated based on current procurement requirements and supply chain conditions.
