5KP70 Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The 5KP70 is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. The device features a 70V reverse standoff voltage rating, 5000W peak pulse power capability, and through-hole P600 axial packaging. The 5KP70 is classified as obsolete, necessitating identification of active equivalent and substitute parts that maintain functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP70 is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 70V
• Voltage - Breakdown (Min): 77.8V or higher
• Power - Peak Pulse: 5000W (5kW)
• Type: Zener, Unidirectional
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• RoHS Status: ROHS3 Compliant

Substitute parts must maintain identical reverse standoff voltage, peak pulse power rating, unidirectional channel configuration, through-hole mounting, and P600 axial package specifications. Voltage clamping characteristics may vary within acceptable limits for the application category.

Parameter Comparison

Engineering Selection Recommendations

The 5KP70 is obsolete; active substitutes are required for new designs and component replenishment.

5KP70A (Littelfuse Inc.) is a direct manufacturer equivalent in active production status. It maintains identical reverse standoff voltage, peak pulse power rating, and package specifications. The part is ROHS3 compliant and available in Cut Tape packaging. Voltage clamping is 113V, which is lower than the original 118.65V specification.

5KP70E3/TR13 (Microchip Technology) is an active manufacturer-recommended substitute. It maintains identical reverse standoff voltage, peak pulse power rating, and package specifications. The part is ROHS3 compliant and available in Tape & Reel packaging. Voltage clamping is 125V, which is higher than the original 118.65V specification. REACH status is unaffected.

Both substitutes satisfy the core electrical and mechanical requirements for P600 axial through-hole TVS diode applications with 70V standoff voltage and 5000W peak pulse power capability.

Frequently Asked Questions (FAQ)

Q: Can 5KP70A be used as a direct replacement for 5KP70?

A: Yes. Both parts share identical reverse standoff voltage (70V), peak pulse power rating (5000W), unidirectional channel configuration, through-hole mounting, and P600 axial package specifications. The 5KP70A is in active production status, whereas the 5KP70 is obsolete.

Q: What is the difference between 5KP70A and 5KP70E3/TR13?

A: Both are functionally equivalent substitutes for the 5KP70. The primary differences are manufacturer (Littelfuse vs. Microchip Technology), packaging format (Cut Tape vs. Tape & Reel), and voltage clamping characteristics (113V vs. 125V). Both maintain the 70V reverse standoff voltage and 5000W peak pulse power rating.

Q: Does packaging format affect electrical performance?

A: No. Cut Tape (CT) and Tape & Reel (TR) packaging formats are supply chain and assembly process considerations only. Electrical performance and device specifications remain identical.

Q: Are both substitutes RoHS compliant?

A: Yes. Both 5KP70A and 5KP70E3/TR13 are ROHS3 compliant, matching the original 5KP70 specification.

Q: What is the operating temperature range for substitute parts?

A: Both substitute parts operate across -55°C to 175°C (TJ), identical to the original 5KP70 specification.
