Part Overview

The 5KP28CE3/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 28V reverse standoff voltage and provides 50V clamping at peak pulse current, delivering 5kW peak pulse power dissipation. The component is housed in a P600 axial through-hole package and is supplied in Tape & Reel packaging format.

The 5KP28CE3/TR13 maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating. Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, and support alternative sourcing strategies while maintaining electrical and mechanical compatibility within specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP28CE3/TR13 are qualified based on the following critical parameters that determine functional equivalence:

Voltage Parameters: Reverse standoff voltage of 28V (typical), breakdown voltage minimum of 31.1V, and clamping voltage maximum of 50V at peak pulse current establish the primary voltage protection window. Substitute parts must operate within these voltage specifications to ensure proper transient suppression without affecting circuit operation during normal conditions.

Current and Power Ratings: Peak pulse current of 100A at 10/1000µs pulse width and 5kW peak pulse power dissipation define the transient energy handling capability. Substitute parts meeting or exceeding these ratings maintain equivalent protection performance.

Package and Mounting: The P600 axial through-hole package and physical form factor are mandatory for mechanical compatibility with existing printed circuit board layouts and assembly processes.

Electrical Type: Bidirectional Zener diode configuration with single channel operation ensures identical circuit behavior and protection characteristics.

Compliance and Environmental: ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and operating temperature range of -55°C to 175°C (TJ) establish regulatory and environmental compatibility requirements.

Parameter Comparison

Engineering Selection Recommendations

30KPA28CA (MDE Semiconductor Inc): This substitute part maintains identical voltage specifications (28V reverse standoff, 31.3V breakdown minimum, 50V clamping maximum) and operating temperature range (-55°C to 175°C). The 30KPA28CA exceeds the current and power ratings of the main part, providing 606A peak pulse current and 30kW peak pulse power dissipation compared to 100A and 5kW respectively. This higher rating capability ensures equivalent or superior transient suppression performance. The part is ROHS3 compliant with unlimited MSL rating. Packaging is supplied in Bulk format rather than Tape & Reel, which may require consideration for automated assembly processes. The 30KPA28CA is suitable for applications requiring enhanced transient energy handling or where supply chain availability of the main part is constrained.

5KP28CA (Diotec Semiconductor): This substitute part matches the main part's voltage standoff (28V) and breakdown specifications (31.1V minimum). The clamping voltage is specified at 45.4V maximum, which is lower than the main part's 50V specification. Peak pulse current is 110A, slightly exceeding the main part's 100A rating, with identical 5kW peak pulse power dissipation. Operating temperature range extends to -50°C minimum (compared to -55°C for the main part), representing a narrower low-temperature specification. RoHS compliance status is listed as Not applicable, and MSL rating is Not Applicable, indicating potential differences in regulatory documentation or manufacturing standards. The 5KP28CA is supplied in Tape & Reel packaging, matching the main part's format. This substitute is appropriate for applications where the lower clamping voltage specification is acceptable and where regulatory compliance documentation aligns with vendor-defined standards.

Both substitute parts maintain P600 axial through-hole package compatibility, ensuring direct mechanical and electrical interchangeability in existing circuit designs. Selection between substitutes depends on specific application requirements regarding transient energy handling, regulatory compliance documentation, and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can the 30KPA28CA be used as a direct replacement for the 5KP28CE3/TR13?

A: The 30KPA28CA is electrically compatible as a substitute. Both parts share identical 28V reverse standoff voltage, 31V+ breakdown voltage, and 50V clamping voltage specifications. The 30KPA28CA's higher current rating (606A vs. 100A) and power rating (30kW vs. 5kW) provide equivalent or superior transient suppression. However, the 30KPA28CA is supplied in Bulk packaging rather than Tape & Reel format, which may require process adjustments for automated assembly operations.

Q: What is the primary difference between the 5KP28CA and the main part 5KP28CE3/TR13?

A: The 5KP28CA has a clamping voltage specification of 45.4V maximum, compared to 50V for the main part. This represents a 4.6V lower clamping point. Both parts maintain the same 28V reverse standoff voltage and 31.1V breakdown minimum. The 5KP28CA's operating temperature minimum is -50°C versus -55°C for the main part. Both are supplied in Tape & Reel packaging and deliver 5kW peak pulse power.

Q: Are all three parts (main and two substitutes) housed in the same P600 axial package?

A: Yes. The 5KP28CE3/TR13, 30KPA28CA, and 5KP28CA are all specified with P600 axial through-hole package configuration. This ensures mechanical compatibility and direct board-level interchangeability without layout modifications.

Q: What compliance certifications apply to each part?

A: The 5KP28CE3/TR13 and 30KPA28CA are both ROHS3 compliant with unlimited MSL rating (MSL 1). The 5KP28CA lists RoHS status as Not applicable and MSL as Not Applicable, indicating different compliance documentation standards. All three parts are classified under ECCN EAR99 for export control purposes.

Q: Which substitute part should be selected for maximum transient energy handling?

A: The 30KPA28CA provides the highest transient energy handling capability with 30kW peak pulse power dissipation and 606A peak pulse current, compared to 5kW and 100A for the main part. This part is suitable for applications requiring enhanced overvoltage protection margin or where transient events exceed the main part's specifications.

Q: Can the 5KP28CA be used in applications requiring operation below -50°C?

A: No. The 5KP28CA specifies a minimum operating temperature of -50°C (TJ), whereas the main part 5KP28CE3/TR13 operates to -55°C. Applications requiring operation at -55°C must use the main part or the 30KPA28CA, both of which support this lower temperature specification.

Q: Are there packaging format differences between the substitutes?

A: Yes. The 5KP28CE3/TR13 and 5KP28CA are supplied in Tape & Reel (TR) format, suitable for automated pick-and-place assembly. The 30KPA28CA is supplied in Bulk format, which may require manual handling or alternative feeder systems for automated assembly processes.
