Substitute Part Grouping Explanation

Substitution eligibility for the 5KP36CE3/TR13 is determined by the following critical parameters:

Voltage Class Compatibility: All substitute parts maintain a 36V nominal reverse standoff voltage with breakdown voltages between 40V and 40.9V, ensuring operation within the same protection threshold.

Clamping Voltage Range: Substitute parts exhibit clamping voltages between 49.9V and 64.3V at peak pulse current, providing equivalent transient suppression characteristics.

Mounting and Package: Substitutes are classified into two groups: P600 axial Through Hole packages (direct mechanical equivalents) and DO-15 axial Through Hole packages (alternative form factor).

Power Dissipation: Substitute parts range from 600W to 30000W peak pulse power. Parts with equal or greater power ratings (5000W or higher) provide direct functional equivalence. Parts with lower power ratings (600W) are suitable for lower-energy transient environments.

Bidirectional Operation: All substitutes maintain single-channel bidirectional Zener diode topology for symmetric overvoltage protection.

Compliance and Status: All substitute parts are Active status with ROHS3 compliance, ensuring regulatory alignment with the main part.

Engineering Selection Recommendations

Direct P600 Package Equivalents (Recommended for Pin-Compatible Replacement):

The 5KP36CA (Diotec Semiconductor) provides the closest functional match with identical 5000W power rating, P600 axial package, and 36V voltage class. Operating temperature range extends to 175°C, matching the main part specification.

The 15KPA36CA (MDE Semiconductor Inc) and 30KPA36CA (Good-Ark Semiconductor) maintain P600 package compatibility with elevated power ratings (15000W and 30000W respectively), suitable for applications requiring enhanced transient energy absorption. The 30KPA36CA operates to 150°C maximum junction temperature, which is 25°C lower than the main part.

Higher Power Density Alternative:

The 15KP36CA-TP (Micro Commercial Co) delivers 15000W peak pulse power in an R-6 axial package. This part requires mechanical board layout modification due to different package geometry but maintains full voltage class compatibility and -55°C to 175°C operating range.

Lower Power Applications:

The P6KE36CA (Taiwan Semiconductor Corporation) and P6KE43CA (Fairchild Semiconductor) are DO-15 package devices rated at 600W peak pulse power. These parts are suitable only for low-energy transient suppression applications and require PCB footprint redesign. The P6KE43CA exhibits a slightly elevated reverse standoff voltage (36.8V) within acceptable tolerance.

Compliance Verification:

All substitute parts maintain Active product status and ROHS3 compliance. The 15KPA36CA lists REACH status as "info available upon request," requiring confirmation before procurement for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the 5KP36CA directly replace the 5KP36CE3/TR13 without board modification?

A: Yes. The 5KP36CA shares identical P600 axial Through Hole package geometry, 36V voltage class, and 5000W power rating. Functional performance is equivalent. Packaging format differs (Cut Tape versus Tape & Reel), which affects supply chain handling but not component operation.

Q: What is the difference between P600 and R-6 package formats?

A: Both are axial Through Hole packages for 36V TVS diodes. P600 and R-6 represent different physical dimensions and lead spacing. The 15KP36CA-TP uses R-6 format, requiring PCB footprint verification before substitution. Electrical performance is independent of package format.

Q: Can I use the 30KPA36CA in place of the 5KP36CE3/TR13?

A: The 30KPA36CA is electrically compatible with 36V voltage class and P600 package matching. However, the maximum operating temperature is 150°C versus 175°C for the main part. Substitution is valid for applications operating below 150°C junction temperature. The 30000W power rating exceeds application requirements but does not create functional incompatibility.

Q: Why do the P6KE36CA and P6KE43CA have lower power ratings?

A: These parts use DO-15 package format, which has lower thermal dissipation capability than P600 packages. The 600W rating reflects this physical constraint. These parts are suitable only for low-energy transient environments and require complete PCB redesign due to different lead spacing and package dimensions.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant certification, matching the main part's regulatory status. The 15KPA36CA requires REACH status confirmation from the manufacturer before use in regulated applications.

Q: What is the significance of clamping voltage differences between substitutes?

A: Clamping voltage determines the peak voltage presented to protected circuitry during transient events. The main part clamps at 64.3V maximum. Substitute parts range from 49.9V to 61.8V. Lower clamping voltages provide tighter protection margins; higher values allow greater transient voltage before suppression. Selection depends on downstream component voltage ratings and application transient severity.

Q: Can I substitute a 15000W part for a 5000W requirement?

A: Yes. Higher power rating indicates greater transient energy absorption capacity. The 15KPA36CA and 15KP36CA-TP both deliver 15000W, providing design margin for unexpected transient events. No functional degradation occurs from oversizing power dissipation capability.

Q: What packaging considerations apply to the 15KP36CA-TP?

A: The 15KP36CA-TP uses Cut Tape packaging and R-6 axial format. Cut Tape requires manual component handling during assembly, unlike Tape & Reel automation. The R-6 package has different lead spacing than P600, necessitating PCB footprint verification. Electrical performance is unaffected by these supply and packaging differences.
