P6KE130CA-T Equivalent & Substitute Parts

Part Overview

The P6KE130CA-T is a transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection in through-hole applications. This bidirectional Zener diode operates with a reverse standoff voltage of 111V and provides clamping at 179V maximum, with a peak pulse current rating of 3.3A at 600W peak pulse power. The component is currently classified as obsolete, necessitating identification of active equivalent parts that maintain identical electrical and mechanical specifications for continued system support and new designs.

Substitute Part Grouping Explanation

Substitution of the P6KE130CA-T is determined by strict equivalence across the following critical parameters:

Voltage - Reverse Standoff: 111V (±tolerance)
Voltage - Breakdown (Min): 124V
Voltage - Clamping (Max) @ Ipp: 179V
Current - Peak Pulse (10/1000µs): 3.3A minimum
Power - Peak Pulse: 600W
Mounting Type: Through Hole
Package / Case: DO-15 or DO-204AC compatible
Type: Zener, Bidirectional, Single Channel

Substitute parts are grouped into two categories: direct electrical equivalents with identical specifications, and manufacturer-recommended alternatives that maintain all critical electrical parameters while offering active product status and improved availability.

Engineering Selection Recommendations

Direct Electrical Equivalents (Identical Specifications):

P6KE130CA-AP, P6KE130CA-BP, and P6KE130CA-TP from Micro Commercial Co are direct substitutes with identical electrical parameters (111V standoff, 179V clamping, 3.3A peak pulse current) and matching operating temperature range (-55°C ~ 175°C). These parts are currently active and available in bulk or cut tape packaging. All three maintain ROHS3 compliance and are suitable for immediate replacement in existing designs.

Manufacturer-Recommended Alternatives (Enhanced Current Rating):

P6KE130CA from Taiwan Semiconductor Corporation and P6KE130CA-B from Littelfuse Inc. provide enhanced peak pulse current ratings of 3.4A while maintaining all other critical electrical parameters. Both are active products with ROHS3 compliance. The Taiwan Semiconductor part is available in tape & reel packaging with the highest inventory (2276 Pcs). The Littelfuse part is supplied in bulk packaging with DO-204AC (DO-15) package designation.

Axial Package Alternative:

P6KE130CAE3/TR13 from Microsemi Corporation maintains identical electrical specifications but uses an axial through-hole package (T-18) instead of DO-15. This part is suitable only for applications where axial package geometry is acceptable. Operating temperature range is -65°C ~ 150°C, which is narrower than the original specification.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance and EAR99 ECCN classification. Moisture sensitivity level is 1 (Unlimited) for all parts. REACH status varies: Diodes Incorporated original is REACH Affected; all substitutes are REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can P6KE130CA-AP, P6KE130CA-BP, and P6KE130CA-TP be used interchangeably with P6KE130CA-T?

A: Yes. These three parts from Micro Commercial Co are direct electrical equivalents with identical voltage ratings (111V standoff, 179V clamping), current ratings (3.3A peak pulse), power dissipation (600W), and operating temperature range (-55°C ~ 175°C). The differences are packaging format (bulk, cut tape) and supplier designation suffix. All are suitable for direct replacement in existing designs.

Q: What is the difference between P6KE130CA-T and P6KE130CA-B?

A: Both parts maintain identical voltage and power specifications. The primary difference is the peak pulse current rating: P6KE130CA-T is rated at 3.3A, while P6KE130CA-B is rated at 3.4A. This higher current capability in the Littelfuse part provides additional margin in transient protection applications. Both operate across -55°C ~ 175°C and are ROHS3 compliant.

Q: Is the Taiwan Semiconductor P6KE130CA suitable as a replacement?

A: Yes, with consideration of the enhanced current rating. The Taiwan Semiconductor part provides 3.4A peak pulse current compared to the original 3.3A specification, offering improved transient handling capability. All voltage parameters are identical. Operating temperature range is not specified in the datasheet, which may require verification for temperature-critical applications.

Q: Can the axial package P6KE130CAE3/TR13 replace the DO-15 package P6KE130CA-T?

A: Electrical substitution is valid; however, mechanical compatibility must be confirmed. The P6KE130CAE3/TR13 uses an axial through-hole package (T-18) instead of the DO-15 radial package. This requires different PCB footprint and lead spacing. Additionally, the operating temperature range (-65°C ~ 150°C) is narrower than the original (-55°C ~ 175°C), which may be limiting in high-temperature applications.

Q: What packaging options are available for P6KE130 series substitutes?

A: Substitute parts are available in three packaging formats: Bulk (loose components), Cut Tape (CT), and Tape & Reel (TR). Bulk packaging is suitable for small-quantity assembly or repair. Cut tape is appropriate for semi-automated pick-and-place operations. Tape & reel is standard for high-volume automated assembly. The axial variant (P6KE130CAE3/TR13) uses a different physical package format entirely.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance. The original P6KE130CA-T is also ROHS3 compliant. REACH status differs: the original part is REACH Affected, while all substitute parts are REACH Unaffected, which may be advantageous for certain supply chain requirements.

Q: Which substitute offers the best availability?

A: Taiwan Semiconductor Corporation's P6KE130CA offers the highest inventory at 2276 Pcs. Micro Commercial Co's P6KE130CA-TP provides 1109 Pcs in cut tape format. For bulk packaging, Littelfuse's P6KE130CA-B has 843 Pcs available. Selection should balance availability with packaging requirements for your assembly process.
