5KP75CA-B Equivalent & Substitute Parts

Part Overview

The 5KP75CA-B is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient protection applications. This through-hole component operates with a 75V reverse standoff voltage and provides 5000W peak pulse power dissipation. The part is currently in active production status with 829 units available in bulk packaging. Alternative equivalent parts may be required due to packaging format availability, lead time considerations, or inventory constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP75CA-B is determined by the following critical parameters:

• Voltage - Reverse Standoff: 75V (exact match required)
• Voltage - Clamping (Max) @ Ipp: 121V (exact match required)
• Power - Peak Pulse: 5000W (exact match required)
• Package / Case: P600, Axial (exact match required)
• Mounting Type: Through Hole (exact match required)
• Type: Zener, Bidirectional (exact match required)

The 5KP75CA manufactured by Diotec Semiconductor meets all critical substitution criteria. Minor variations in peak pulse current (41A vs. 42.1A) and operating temperature range remain within acceptable tolerance for general-purpose TVS applications while maintaining identical voltage protection characteristics and power dissipation capability.

Parameter Comparison

Engineering Selection Recommendations

Both the 5KP75CA-B and 5KP75CA are active production components with ROHS3 compliance certification. The Littelfuse 5KP75CA-B is supplied in bulk packaging with 829 units in stock. The Diotec 5KP75CA is supplied in Tape & Reel format with 3900 units available. Selection between these parts should be based on packaging requirements and inventory availability. Both components satisfy identical electrical specifications for 75V transient voltage suppression applications with 5000W peak pulse power handling.

Frequently Asked Questions (FAQ)

Q: Can the Diotec 5KP75CA replace the Littelfuse 5KP75CA-B in production assemblies?

A: Yes. Both components share identical voltage ratings (75V standoff, 121V clamping), power dissipation (5000W), and package geometry (P600 axial through-hole). The 1.1A difference in peak pulse current specification does not affect functional compatibility for general-purpose transient protection circuits.

Q: What is the significance of the packaging format difference (Bulk vs. Tape & Reel)?

A: Bulk packaging is suitable for manual assembly or small-volume applications. Tape & Reel packaging is optimized for automated pick-and-place assembly processes. The electrical and mechanical properties of the components are identical; packaging format selection depends on assembly methodology and volume requirements.

Q: Are there temperature range limitations when substituting the Diotec part?

A: The Diotec 5KP75CA operates from -50°C to 175°C, compared to -55°C to 175°C for the Littelfuse part. If your application requires operation below -50°C, the Littelfuse 5KP75CA-B is required. For applications within the -50°C to 175°C range, both parts are functionally equivalent.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the 5KP75CA-B and 5KP75CA are ROHS3 compliant. The Littelfuse part carries full REACH compliance status, while the Diotec part indicates REACH information is available upon request. Verify REACH documentation with the supplier if regulatory compliance documentation is required for your application.
