5KP13-E3/73 Equivalent & Substitute Parts

Part Overview

The 5KP13-E3/73 is a unidirectional Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, designed for general-purpose transient protection applications. This part operates with a 13V reverse standoff voltage and provides 5000W peak pulse power dissipation in a through-hole P600 axial package. The 5KP13-E3/73 is currently classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 5KP13-E3/73 is determined by the following critical parameters:

• Voltage Rating: Reverse standoff voltage of 13V and breakdown voltage minimum of 14.4V
• Clamping Voltage: Maximum clamping voltage at peak pulse current
• Peak Pulse Current: 210A minimum capability at 10/1000µs waveform
• Power Dissipation: 5000W peak pulse power rating
• Package Compatibility: P600 axial through-hole package
• Temperature Range: -55°C to 175°C operating range
• Compliance: ROHS3 compliance and REACH unaffected status

Substitute parts must maintain identical voltage ratings, equivalent or superior peak pulse current handling, and compatible package specifications. Variations in clamping voltage within the specified range are acceptable provided all other electrical parameters remain within tolerance.

Parameter Comparison

Engineering Selection Recommendations

5KP13A-E3/73 (Vishay): Direct substitute with active product status. Maintains identical voltage ratings and temperature range. Clamping voltage reduced to 21.5V with increased peak pulse current to 233A, providing improved transient suppression performance. ROHS3 compliant.

5KP13E3/TR13 (Microchip): Electrical equivalent with identical clamping voltage (23.8V) and peak pulse current (210A) specifications. Available in tape and reel packaging. Active product status with ROHS3 compliance. Suitable for automated assembly processes.

SLD13U-017 (Littelfuse): Manufacturer-recommended substitute with AEC-Q101 automotive qualification. Clamping voltage of 21.5V with superior peak pulse current rating of 237.2A. Tape and reel packaging. Active status with ROHS3 compliance and automotive-grade reliability.

SLD13U-017-B (Littelfuse): Identical electrical specifications to SLD13U-017 with bulk packaging. AEC-Q101 qualified for automotive applications. Active product status with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the 5KP13A-E3/73 replace the obsolete 5KP13-E3/73 in existing designs?

A: Yes. The 5KP13A-E3/73 maintains the same 13V reverse standoff voltage, 14.4V minimum breakdown voltage, and 5000W peak pulse power rating. The reduced clamping voltage (21.5V vs. 23.8V) and increased peak pulse current (233A vs. 210A) provide equivalent or superior transient protection performance in the same P600 axial through-hole package.

Q: What is the difference between SLD13U-017 and SLD13U-017-B?

A: Both parts are electrically identical with 13V standoff voltage, 21.5V clamping voltage, and 237.2A peak pulse current. The primary difference is packaging: SLD13U-017 is supplied in tape and reel format for automated assembly, while SLD13U-017-B is supplied in bulk packaging. Both are AEC-Q101 qualified and ROHS3 compliant.

Q: Is the 5KP13E3/TR13 from Microchip a direct replacement?

A: Yes. The 5KP13E3/TR13 provides identical electrical performance to the original 5KP13-E3/73 with 23.8V clamping voltage and 210A peak pulse current. It is available in tape and reel packaging and maintains full ROHS3 compliance. The primary difference is the packaging format, which is suitable for high-volume automated production.

Q: Are all substitute parts suitable for automotive applications?

A: The SLD13U-017 and SLD13U-017-B from Littelfuse carry AEC-Q101 automotive qualification. The Vishay 5KP13A-E3/73 and Microchip 5KP13E3/TR13 do not specify automotive qualification. Selection should be based on application requirements.

Q: Do all substitute parts meet the same compliance standards?

A: All listed substitute parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. All maintain the same HTSUS code (8541.10.0080) and moisture sensitivity level (MSL 1 - Unlimited).
