5KP17CE3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP17CE3/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 17V reverse standoff voltage and provides 30.5V clamping at peak pulse current. The device is packaged in P600 axial through-hole configuration and is supplied on tape and reel. The part maintains active product status and is RoHS3 compliant with unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching electrical performance parameters, package compatibility, and operational specifications. Substitution candidates must maintain compatible reverse standoff voltage, clamping voltage, peak pulse current ratings, and thermal operating ranges to ensure functional equivalence in circuit protection applications.

Substitute Part Grouping Explanation

Substitution of the 5KP17CE3/TR13 is determined by alignment of critical electrical parameters: reverse standoff voltage, breakdown voltage, clamping voltage, and peak pulse current rating. The primary substitution criterion is the 17V reverse standoff voltage specification, which defines the protection threshold for the application circuit.

Substitute parts are grouped into two categories based on package compatibility:

Category 1: P600 Axial Package (Direct Package Match) Parts maintaining the P600 axial through-hole package allow direct board-level substitution without layout modification. The 15KPA17CA from MDE Semiconductor Inc. matches the P600 package and 17V standoff voltage specification, with enhanced peak pulse current capability (515.4A versus 164A) and higher power dissipation (15kW versus 5kW).

Category 2: DO-15 (DO-204AC) Axial Package (Package Variant) Parts utilizing the DO-15 (DO-204AC) axial through-hole package provide functional substitution with package footprint differences. The P6KE18CA from Diotec Semiconductor and SA15CA-B from Littelfuse Inc. operate in the 15V to 15.3V standoff voltage range with reduced peak pulse current ratings (25A and 20.9A respectively) and lower power dissipation (600W and 500W respectively).

Substitution logic is based on the following allowed parameters: reverse standoff voltage tolerance, breakdown voltage range, clamping voltage specification, peak pulse current capability, power dissipation rating, operating temperature range, package type, and compliance certifications.

Engineering Selection Recommendations

15KPA17CA (MDE Semiconductor Inc.)

The 15KPA17CA provides direct electrical and package compatibility with the 5KP17CE3/TR13. Both devices maintain identical 17V reverse standoff voltage and P600 axial through-hole packaging. The 15KPA17CA demonstrates superior performance characteristics with 515.4A peak pulse current and 15kW power dissipation, compared to the main part's 164A and 5kW ratings. Clamping voltage is marginally lower at 29.3V versus 30.5V. Both parts maintain -55 to 175°C operating temperature range and RoHS3 compliance. This substitute is suitable for applications requiring enhanced transient energy absorption capacity within the same package footprint.

P6KE18CA (Diotec Semiconductor)

The P6KE18CA operates with a 15.3V reverse standoff voltage and utilizes the DO-15 (DO-204AC) axial through-hole package. This represents a package variant substitution with reduced electrical performance specifications. Peak pulse current is 25A and power dissipation is 600W, substantially lower than the main part. Clamping voltage is 25.2V. The operating temperature range extends to -50°C minimum, compared to -55°C for the main part. RoHS compliance status is not applicable. This substitute is applicable only in applications where reduced transient current handling is acceptable and package footprint modification is feasible.

SA15CA-B (Littelfuse Inc.)

The SA15CA-B operates with a 15V reverse standoff voltage and utilizes the DO-15 (DO-204AC) axial through-hole package. This represents a package variant substitution with reduced electrical performance specifications. Peak pulse current is 20.9A and power dissipation is 500W, substantially lower than the main part. Clamping voltage is 24.4V. The operating temperature range matches the main part at -55 to 175°C. RoHS3 compliance and REACH unaffected status align with the main part. This substitute is applicable only in applications where reduced transient current handling is acceptable and package footprint modification is feasible.

Frequently Asked Questions (FAQ)

Q: Can the 15KPA17CA directly replace the 5KP17CE3/TR13 without circuit board modification?

A: Yes. The 15KPA17CA maintains identical P600 axial through-hole package configuration and 17V reverse standoff voltage specification. Direct board-level substitution is possible without layout changes. The enhanced current and power ratings provide improved transient suppression capability.

Q: What is the primary difference between the 5KP17CE3/TR13 and the P6KE18CA?

A: The primary differences are package type and electrical performance. The P6KE18CA uses DO-15 (DO-204AC) package versus P600 for the main part. The P6KE18CA operates at 15.3V reverse standoff voltage with 25A peak pulse current and 600W power dissipation, compared to 17V, 164A, and 5000W for the main part. Package footprint modification is required for substitution.

Q: Are the DO-15 package substitutes (P6KE18CA and SA15CA-B) suitable for high-current transient protection?

A: No. Both DO-15 package options provide significantly reduced peak pulse current ratings (25A and 20.9A respectively) compared to the main part's 164A specification. These substitutes are applicable only in low-current transient protection applications. High-current applications require the P600 package options.

Q: What compliance certifications should be verified when substituting parts?

A: Verify RoHS3 compliance status and REACH regulatory status for your application requirements. The 5KP17CE3/TR13, 15KPA17CA, and SA15CA-B are RoHS3 compliant with REACH unaffected status. The P6KE18CA has not applicable RoHS status and vendor undefined REACH status, requiring additional compliance verification.

Q: Can the SA15CA-B substitute for the 5KP17CE3/TR13 in a 17V protection circuit?

A: The SA15CA-B operates at 15V reverse standoff voltage, which is 2V lower than the 5KP17CE3/TR13's 17V specification. This voltage difference affects circuit protection threshold and may result in premature device activation. Substitution is not recommended for applications requiring precise 17V standoff voltage specification.

Q: What is the temperature operating range difference between substitutes?

A: The 5KP17CE3/TR13, 15KPA17CA, and SA15CA-B all operate across -55 to 175°C. The P6KE18CA has a minimum operating temperature of -50°C, which is 5°C higher than the other options. For applications requiring -55°C operation, the P6KE18CA is not suitable.

Q: How do peak pulse current ratings affect substitute selection?

A: Peak pulse current rating determines the maximum transient current the device can suppress. The 5KP17CE3/TR13 handles 164A, the 15KPA17CA handles 515.4A, while the P6KE18CA and SA15CA-B handle 25A and 20.9A respectively. Select a substitute with peak pulse current rating equal to or greater than the application requirement.
