5KP12AE3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP12AE3/TR13 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose transient voltage protection applications. This component features a 12V reverse standoff voltage with a 19.9V maximum clamping voltage and peak pulse current rating of 251A at 5000W peak pulse power. The device is packaged in P600 axial through-hole configuration and supplied on tape and reel. The part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity level rating. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when specific packaging or inventory requirements necessitate component substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitution of TVS diodes is determined by electrical parameter equivalence and mechanical compatibility. The primary criteria for substitution are:

Electrical Parameters:

• Voltage - Reverse Standoff (Typ): 12V
• Voltage - Breakdown (Min): 13.3V
• Voltage - Clamping (Max) @ Ipp: 19.9V
• Current - Peak Pulse (10/1000µs): 251A minimum
• Power - Peak Pulse: 5000W minimum

Mechanical Parameters:

• Mounting Type: Through Hole
• Package / Case: P600 Axial or equivalent axial configuration
• Operating Temperature Range: -55°C to 175°C (TJ)

Compliance Parameters:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts are classified into two categories:

Direct Equivalent (5KP12A-E3/54): Identical electrical specifications and P600 axial package with alternative packaging format (Cut Tape vs. Tape & Reel).

Functional Equivalent (5KP12A, LCE12A): Parts meeting core voltage and temperature specifications with variations in peak pulse current rating or package configuration. The 5KP12A variant provides higher peak pulse current (256.3A) in P600 package. The LCE12A provides reduced peak pulse current (75A) with DO-201 package configuration, suitable for lower-current applications.

Parameter Comparison

Engineering Selection Recommendations

5KP12A-E3/54 (Vishay General Semiconductor): This part is the direct electrical equivalent to the 5KP12AE3/TR13, matching all voltage specifications, peak pulse current, and power ratings. The primary difference is packaging format (Cut Tape versus Tape & Reel). This substitute is suitable for applications requiring identical electrical performance with alternative supply format. The part maintains active product status, ROHS3 compliance, and unlimited moisture sensitivity rating. Selection of this part is appropriate when tape and reel packaging is not a requirement.

5KP12A (Littelfuse Inc.): This part meets all core electrical specifications with a marginally higher peak pulse current rating (256.3A versus 251A), providing equivalent or superior performance in the 12V protection class. The P600 axial package maintains mechanical compatibility with the original design. This substitute is suitable for direct replacement in applications where the higher current rating provides additional design margin. The part maintains active product status and full compliance certifications.

LCE12A (Littelfuse): This part provides identical voltage specifications and operating temperature range but with reduced peak pulse current (75A) and power rating (1500W). The DO-201 package differs from the P600 configuration, requiring mechanical board layout verification. This substitute is suitable only for applications with lower transient current requirements or where space constraints favor the DO-201 package form factor. Selection requires confirmation that the 75A peak pulse current is adequate for the intended application.

Frequently Asked Questions (FAQ)

Q: Can the 5KP12A-E3/54 be used as a direct replacement for the 5KP12AE3/TR13?

A: Yes. The 5KP12A-E3/54 is electrically identical to the 5KP12AE3/TR13, with matching voltage specifications (12V standoff, 19.9V clamping), peak pulse current (251A), and power rating (5000W). The only difference is packaging format: the substitute is supplied in Cut Tape format rather than Tape & Reel. Both parts use the P600 axial through-hole package and maintain identical compliance certifications.

Q: What is the difference between the 5KP12A and the 5KP12AE3/TR13?

A: The 5KP12A provides a marginally higher peak pulse current rating (256.3A compared to 251A) while maintaining identical voltage specifications and 5000W power rating. Both parts use the P600 axial package and operate across the same temperature range (-55°C to 175°C). The 5KP12A is suitable for applications where the additional current margin provides design flexibility.

Q: Can the LCE12A replace the 5KP12AE3/TR13 in all applications?

A: The LCE12A matches the voltage specifications but has reduced peak pulse current (75A versus 251A) and power rating (1500W versus 5000W). Additionally, the LCE12A uses a DO-201 package rather than P600. This substitute is suitable only for applications with lower transient current requirements and where the DO-201 package is mechanically compatible with the board design. Verification of current requirements is necessary before substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (5KP12A-E3/54, 5KP12A, and LCE12A) are ROHS3 compliant with unlimited moisture sensitivity level rating, matching the compliance status of the 5KP12AE3/TR13.

Q: What is the significance of the P600 versus DO-201 package difference?

A: The P600 and DO-201 are both axial through-hole packages but have different physical dimensions and lead spacing. The P600 package is larger and accommodates higher power dissipation. The DO-201 package is more compact. Board layout and PCB hole spacing must be verified before substituting between these package types. The LCE12A (DO-201) is not mechanically interchangeable with the P600-packaged parts without board redesign.

Q: What does the peak pulse current rating indicate?

A: The peak pulse current rating (measured at 10/1000µs pulse duration) indicates the maximum transient current the TVS diode can safely suppress. The 5KP12AE3/TR13 and its direct equivalent (5KP12A-E3/54) are rated for 251A peak pulse current. Higher ratings indicate greater transient suppression capability. Applications with higher transient currents require parts with correspondingly higher peak pulse current ratings.

Q: Can packaging format (Tape & Reel versus Cut Tape) affect component performance?

A: No. Packaging format affects only supply and handling logistics, not electrical or thermal performance. The 5KP12AE3/TR13 (Tape & Reel) and 5KP12A-E3/54 (Cut Tape) are electrically and functionally identical. Packaging format selection depends on assembly process requirements and inventory management practices.
