Engineering Selection Recommendations

Group 1 - P600 Package Direct Substitutes:

The 5KP40CA (Diotec Semiconductor) provides the closest electrical equivalence to the 5KP40CE3/TR13, maintaining identical reverse standoff voltage (40V), breakdown voltage (44.4V), and peak pulse power rating (5000W) within the same P600 axial package format. This part is suitable for direct replacement in existing circuit designs. Operating temperature range extends to -50°C minimum, which covers standard industrial applications.

The 15KPA40CA (MDE Semiconductor Inc) offers enhanced transient energy handling with 15000W peak pulse power and 229.5A peak pulse current, maintaining the 40V reverse standoff specification and P600 package compatibility. This part is applicable in applications requiring higher transient suppression capacity while preserving the same voltage protection threshold.

Group 2 - DO-15 Package Alternatives:

The P6KE47CA (Diotec Semiconductor) and SA48CA (Taiwan Semiconductor Corporation) utilize DO-15 (DO-204AC) axial packaging with reduced power dissipation (500W to 600W) and lower peak pulse current ratings (6.7A to 9.7A). These parts are suitable for low-energy transient protection applications where the primary device's 5000W capability exceeds circuit requirements.

All substitute parts maintain RoHS3 compliance and Active product status, ensuring regulatory alignment and continued manufacturing availability. Selection between Group 1 and Group 2 depends on circuit transient energy requirements and available board space for component packaging.

Frequently Asked Questions (FAQ)

Q: Can the 15KPA40CA replace the 5KP40CE3/TR13 in all applications?

A: The 15KPA40CA maintains identical reverse standoff voltage (40V) and package format (P600), with enhanced power dissipation capability (15000W versus 5000W). Substitution is valid for applications where the higher transient energy rating does not create circuit design conflicts. Verify that the increased peak pulse current (229.5A) does not exceed circuit current-limiting specifications.

Q: What is the primary difference between P600 and DO-15 package substitutes?

A: P600 and DO-15 are both through-hole axial package formats with identical mechanical footprints. The primary distinction lies in power dissipation capability: P600 packages support 5000W to 15000W peak pulse power, while DO-15 packages are rated for 500W to 600W. Package selection depends on transient energy requirements and thermal management considerations.

Q: Are the DO-15 package alternatives (P6KE47CA, SA48CA) suitable for high-energy transient protection?

A: No. DO-15 package alternatives are rated for 500W to 600W peak pulse power, compared to the main device's 5000W rating. These parts are applicable only in low-energy transient protection circuits. For applications requiring 5000W or greater transient suppression, P600 package substitutes (5KP40CA or 15KPA40CA) are required.

Q: Does the 5KP40CA have any temperature range limitations compared to the main part?

A: The 5KP40CA operates across -50°C to 175°C, while the 5KP40CE3/TR13 operates across -55°C to 175°C. The 5KP40CA has a 5°C higher minimum operating temperature. Substitution is valid for applications where the -50°C minimum temperature specification is acceptable.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain RoHS3 compliance, ensuring regulatory alignment with environmental and hazardous substance restrictions.

Q: What is the significance of the voltage parameters (Reverse Standoff, Breakdown, Clamping)?

A: Reverse Standoff voltage (40V) defines the normal operating voltage threshold below which the TVS diode remains non-conducting. Breakdown voltage (44.4V to 44.7V) specifies the voltage at which the device begins conducting. Clamping voltage (64.5V to 77.4V) represents the maximum voltage across the device during transient suppression at peak pulse current. These parameters must remain within acceptable ranges for circuit protection specifications.

Q: Can P6KE56CA and SA48CA be used interchangeably?

A: Both parts utilize DO-15 packaging and provide similar low-power transient suppression (500W to 600W). However, P6KE56CA operates at 47.8V reverse standoff with 77V clamping voltage, while SA48CA operates at 48V reverse standoff with 77.4V clamping voltage. Selection depends on specific circuit voltage protection requirements. Operating temperature data for P6KE56CA is not specified in available documentation.
