P4KE130CA-B Equivalent & Substitute Parts

Part Overview

The P4KE130CA-B is an active Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This bidirectional Zener diode operates in the DO-204AL (DO-41) axial through-hole package and provides 400W peak pulse power dissipation with a 179V maximum clamping voltage. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1), making it suitable for standard industrial and commercial environments. Equivalent and substitute parts are identified based on matching electrical specifications and package compatibility to ensure direct functional replacement in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P4KE130CA-B is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 111V
• Voltage - Breakdown (Min): 124V
• Voltage - Clamping (Max) @ Ipp: 179V
• Current - Peak Pulse (10/1000µs): 2.3A
• Power - Peak Pulse: 400W
• Package / Case: DO-204AL (DO-41) Axial
• Mounting Type: Through Hole
• Type: Zener, Bidirectional, Single Channel

The substitute part P4KE130CA, manufactured by Taiwan Semiconductor Corporation, matches all electrical specifications and package requirements. The primary difference is packaging format: the original part is supplied in Bulk, while the substitute is supplied in Tape & Reel (TR) format. This packaging difference does not affect electrical performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both P4KE130CA-B and P4KE130CA are active products with identical electrical performance and mechanical compatibility. Selection between these parts should be based on:

• Packaging Requirements: Choose Bulk packaging (P4KE130CA-B) for low-volume applications or manual assembly. Select Tape & Reel format (P4KE130CA) for automated pick-and-place assembly or high-volume production runs.
• Compliance: Both parts meet ROHS3 compliance and carry REACH Unaffected status, suitable for regulated markets.
• Availability: Verify current inventory levels with your supplier, as stock quantities may vary between manufacturers and packaging formats.

No electrical or thermal performance trade-offs exist between these parts. Direct substitution is valid for all circuit applications requiring 111V standoff voltage TVS protection.

Frequently Asked Questions (FAQ)

Q: Can P4KE130CA (Taiwan Semiconductor) directly replace P4KE130CA-B (Littelfuse) in existing designs?

A: Yes. All electrical parameters, thermal ratings, and mechanical dimensions are identical. The parts are pin-compatible and functionally equivalent in all circuit applications.

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

A: Bulk packaging supplies individual components loose or in bags, suitable for manual assembly and low-volume builds. Tape & Reel packaging places components on continuous carrier tape in reels, optimized for automated assembly equipment. Electrical performance is identical; packaging choice depends on assembly method and production volume.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both P4KE130CA-B and P4KE130CA operate across -55°C to 175°C junction temperature range, supporting industrial and automotive thermal environments.

Q: Do these parts require any design modifications when substituting?

A: No. Both parts use identical DO-204AL (DO-41) axial through-hole package with the same pin spacing and lead configuration. No PCB layout or schematic changes are necessary.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting environmental and hazardous substance restrictions for EU and global markets.
