5KP15CE3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP15CE3/TR13 is a bidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This zener-type TVS diode features a 15V reverse standoff voltage with a 26.9V maximum clamping voltage and 186A peak pulse current capability. The device is rated for 5000W peak pulse power dissipation and operates across a temperature range of -55°C to 175°C. The part is supplied in Tape & Reel packaging with a P600 axial through-hole package configuration.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the critical parameters that define TVS diode functionality: reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, power rating, package type, and operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP15CE3/TR13 are qualified based on matching the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Reverse standoff voltage: 15V (Typ)
• Breakdown voltage minimum: 16.7V
• Power rating: 5000W peak pulse
• Bidirectional operation: 1 channel
• Type: Zener TVS diode
• Operating temperature range: -55°C to 175°C

Mechanical Compatibility Criteria:

• Mounting type: Through hole
• Package family: Axial configuration (P600 or R-6)

Compliance Criteria:

• RoHS3 compliance
• REACH unaffected status
• Product status: Active

The identified substitute parts maintain electrical equivalence within the TVS diode functional class while accommodating minor variations in clamping voltage and peak pulse current that remain within acceptable operating parameters for general-purpose transient suppression applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed—5KP15CE3/TR13, 5KP15CA, and 5KP15CA-TP—are active products with full RoHS3 compliance and REACH unaffected status, qualifying them for use in regulated applications.

5KP15CA (Littelfuse Inc.) maintains identical reverse standoff and breakdown voltage specifications with the main part. The clamping voltage is 2.5V lower (24.4V versus 26.9V), and peak pulse current is 23A higher (209A versus 186A). Both parts share the P600 axial package configuration and identical power rating. This part is suitable for applications where the lower clamping voltage provides acceptable margin and higher current handling capacity is beneficial.

5KP15CA-TP (Micro Commercial Co) maintains identical reverse standoff and breakdown voltage specifications. The clamping voltage matches the 5KP15CA at 24.4V. Peak pulse current is not specified for this part. The package configuration is R-6 axial, which differs from the P600 package of the main part. Physical lead dimensions and PCB footprint compatibility must be evaluated for this substitution based on mechanical constraints of the application.

All parts operate across the identical temperature range (-55°C to 175°C) and maintain the 5000W peak pulse power rating required for general-purpose transient suppression.

Frequently Asked Questions (FAQ)

Q: What defines electrical equivalence for TVS diode substitution?

A: Electrical equivalence is established when reverse standoff voltage, breakdown voltage, power rating, and bidirectional operation specifications match between parts. Minor variations in clamping voltage and peak pulse current are acceptable when the substitute part maintains the same functional voltage protection class and power dissipation capability.

Q: Can the 5KP15CA substitute for the 5KP15CE3/TR13 in all applications?

A: The 5KP15CA is electrically equivalent with matching reverse standoff voltage (15V), breakdown voltage (16.7V), and power rating (5000W). The lower clamping voltage (24.4V versus 26.9V) and higher peak pulse current (209A versus 186A) are compatible with general-purpose transient suppression. Substitution is valid when the application circuit tolerates the 2.5V reduction in maximum clamping voltage.

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

A: Both P600 and R-6 are axial through-hole package configurations for TVS diodes. The package designation indicates physical lead diameter and spacing. Mechanical compatibility depends on PCB footprint design and lead hole sizing. The R-6 package used by the 5KP15CA-TP may not be directly interchangeable with P600 footprints without PCB modification.

Q: Are all three parts suitable for new designs?

A: All three parts carry active product status and full compliance certifications (RoHS3, REACH unaffected). Selection for new designs should prioritize the 5KP15CA or 5KP15CE3/TR13 based on package availability and clamping voltage requirements specific to the circuit design.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, suitable for lower-volume or manual assembly operations. Both packaging formats contain identical components; the difference is in supply format and handling method.

Q: How do I determine if clamping voltage differences affect my application?

A: Clamping voltage determines the maximum voltage that appears across the protected circuit during a transient event. The 5KP15CE3/TR13 clamps at 26.9V maximum, while substitute parts clamp at 24.4V. If your protected circuit components have voltage ratings between 24.4V and 26.9V, the lower clamping voltage of substitute parts provides additional safety margin. If components are rated below 24.4V, all parts provide equivalent protection.
