1.5KE130A-B Equivalent & Substitute Parts

Part Overview

The 1.5KE130A-B is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, rated for 1500W peak pulse power with a 111V reverse standoff voltage and 179V maximum clamping voltage. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The part operates across a temperature range of -55°C to 175°C and is housed in a DO-201 through-hole package suitable for general-purpose transient protection applications.

Substitute Part Grouping Explanation

Substitution eligibility for the 1.5KE130A-B is determined by strict equivalence across the following critical parameters:

Voltage - Reverse Standoff (Typ): 111V
Voltage - Breakdown (Min): 124V (±tolerance)
Voltage - Clamping (Max) @ Ipp: 179V
Current - Peak Pulse (10/1000µs): 8.4A (±tolerance)
Power - Peak Pulse: 1500W
Operating Temperature Range: -55°C to 175°C minimum
Mounting Type: Through Hole
Type: Zener, Unidirectional

Substitute parts are grouped into two categories:

Category A - Direct Electrical Equivalents (Same Power Rating, Same Voltage Class): Parts maintaining identical 1500W power dissipation, 111V standoff voltage, and 179V clamping voltage with peak pulse currents between 8.4A and 8.7A. These parts are interchangeable in applications where the original DO-201 package footprint is preserved.

Category B - Functional Equivalents with Package Variation: Parts meeting all electrical specifications but utilizing alternative through-hole packages (DO-13, DO-15, P600) or higher power ratings. These require mechanical and thermal design review before substitution.

Engineering Selection Recommendations

Primary Substitutes (Direct Replacement):

The following parts are recommended as direct replacements for the obsolete 1.5KE130A-B:

1.5KE130A-E3/54 (Vishay General Semiconductor): Active status, identical electrical specifications, DO-201 package, ROHS3 compliant, REACH unaffected. Suitable for immediate substitution without design modification.
1.5KE130AHE3_A/C (Vishay General Semiconductor): Active status, AEC-Q101 automotive qualified, identical electrical specifications, DO-201 package. Recommended for automotive and high-reliability applications.
1.5KE130A (Taiwan Semiconductor Corporation): Active status, marginally higher peak pulse current (8.7A vs 8.4A), DO-201 package, ROHS3 compliant. Acceptable substitute with thermal margin improvement.
1.5KE130A-B (Littelfuse Inc.): Active status, identical electrical specifications, DO-201 package, ROHS3 compliant. Direct equivalent from alternative manufacturer.

Secondary Substitutes (Package Variation):

1V5KE130A (Taiwan Semiconductor Corporation): Active status, identical electrical specifications, DO-201AD package variant. Suitable if DO-201AD footprint compatibility is confirmed.
1.5KE130A-TP (Micro Commercial Co): Active status, AEC-Q101 automotive qualified, DO-201AE package variant. Requires PCB footprint verification for DO-201AE compatibility.
1N5660A (Solid State Inc.): Active status, identical electrical specifications, DO-13 package. Substitution requires PCB redesign due to different package footprint.

Frequently Asked Questions (FAQ)

Q: Can I substitute 1.5KE130A-E3/54 for the obsolete 1.5KE130A-B without design changes?

A: Yes. The 1.5KE130A-E3/54 maintains identical voltage specifications (111V standoff, 179V clamping), peak pulse current (8.4A), power rating (1500W), and DO-201 package footprint. No circuit or PCB modifications are required.

Q: What is the difference between 1.5KE130A and 1.5KE130A-B?

A: Both parts share identical electrical specifications and DO-201 packaging. The primary difference is manufacturer: 1.5KE130A is manufactured by Taiwan Semiconductor Corporation, while 1.5KE130A-B is manufactured by Littelfuse Inc. The peak pulse current specification shows minor variation (8.7A vs 8.5A), both within acceptable tolerance.

Q: Is the 1N5660A a suitable replacement?

A: The 1N5660A meets all electrical specifications but uses a DO-13 package instead of DO-201. Direct PCB substitution is not possible without footprint redesign. Electrical performance is equivalent.

Q: Can I use the 5KP100E3/TR13 as a substitute?

A: The 5KP100E3/TR13 has a lower standoff voltage (100V vs 111V) and significantly higher power rating (5000W vs 1500W). Substitution is only appropriate if the application can tolerate a lower voltage threshold and the P600 package footprint is compatible. This is not a direct equivalent.

Q: What does AEC-Q101 qualification mean?

A: AEC-Q101 is an automotive electronics qualification standard. Parts bearing this certification (1.5KE130AHE3_A/C, 1.5KE130A-TP, 1N6298A-E3/54) meet automotive reliability and quality requirements and are suitable for automotive applications.

Q: Are all substitute parts ROHS3 compliant?

A: Most substitute parts listed are ROHS3 compliant. Verify compliance status in the component datasheet for specific procurement requirements.

Q: What is the difference between DO-201, DO-201AA, DO-201AD, and DO-201AE packages?

A: These are axial through-hole package variants with minor dimensional differences. DO-201 is the standard designation; DO-201AA, DO-201AD, and DO-201AE are manufacturer-specific variants. Verify PCB footprint compatibility before substitution.

Q: Can I use the P6KE130A-G as a substitute?

A: The P6KE130A-G has a lower power rating (600W vs 1500W) and lower peak pulse current (3.35A vs 8.4A). Substitution is only appropriate in applications with reduced transient energy requirements. This is not a direct equivalent for high-energy transient protection.
