1N6380 Equivalent & Substitute Parts

Part Overview

The 1N6380 is a 36V Transient Voltage Suppressor (TVS) diode manufactured by onsemi, designed for general-purpose overvoltage protection in through-hole axial applications. This component features a 65.2V maximum clamping voltage and 1500W peak pulse power rating. The 1N6380 is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the 1N6380 is determined by the following critical parameters:

Voltage - Reverse Standoff (Typ): Must equal 36V
Unidirectional Channels: Must equal 1
Mounting Type: Must be Through Hole
Type: Must be Zener TVS diode
Applications: General Purpose

Substitute parts are grouped into two categories based on power rating and package compatibility:

Category A - Low Power (1.5kW): Parts with 1500W peak pulse power in DO-201 or equivalent axial packages. These maintain the original power specification and are suitable for direct replacement in space-constrained applications.

Category B - Higher Power (5kW and above): Parts with 5000W, 15000W, or 30000W peak pulse power ratings in P600 or R-6 packages. These provide enhanced transient protection capability and are suitable where increased surge handling is acceptable and physical space permits.

All substitute parts maintain the 36V reverse standoff voltage and single-channel unidirectional configuration required for functional equivalence.

Engineering Selection Recommendations

For Direct Replacement (Same Power Rating)

The LCE36A from Littelfuse Inc. is the primary equivalent for the 1N6380. Both devices share identical 1500W peak pulse power ratings and compatible DO-201 series axial packages. The LCE36A is active and ROHS3 compliant, addressing the obsolescence and compliance limitations of the original part. Operating temperature range matches the 1N6380 specification (-65°C ~ 175°C).

For Enhanced Protection (Higher Power Ratings)

When circuit design permits package size changes, the 5KP36A series (5000W), 15KPA36A series (15000W), and 30KPA36A series (30000W) from Littelfuse Inc. provide increased transient suppression capability. All are active, ROHS3 compliant, and maintain the 36V reverse standoff voltage. The 5KP36A-HR and 5KP36A-HRA variants support the full -55°C ~ 175°C operating range. Higher-power variants (15KPA and 30KPA series) are suitable for applications requiring robust surge protection in industrial or power distribution environments.

For Compact Applications (Lower Power)

The P5KE36A-AP and P5KE36A-BP from Micro Commercial Co offer 500W peak pulse power in DO-15 packages, suitable for space-constrained designs where lower transient energy is acceptable. Both maintain the 36V reverse standoff voltage and -65°C ~ 175°C operating temperature range.

For Comchip Technology Sourcing

The 5KP36A-G from Comchip Technology provides 5000W peak pulse power in R-6 axial package with ROHS3 compliance. Operating temperature range is -55°C ~ 150°C, which is narrower than the 1N6380 specification.

Frequently Asked Questions (FAQ)

Q: Can the LCE36A directly replace the 1N6380 without circuit modification?

A: Yes. The LCE36A maintains the same 36V reverse standoff voltage, 1500W peak pulse power rating, and compatible DO-201 series axial package. Both are single-channel unidirectional Zener TVS diodes for general-purpose applications. The primary difference is that LCE36A is active and ROHS3 compliant, whereas 1N6380 is obsolete and RoHS non-compliant.

Q: What is the difference between 5KP36A-HR and 5KP36A-HRA?

A: Both variants are functionally equivalent with identical electrical specifications: 36V reverse standoff, 40V breakdown minimum, 58.1V clamping maximum, 5000W peak pulse power, and 87.8A peak pulse current. The primary distinction is the series designation (5KP-HR versus 5KP-HRA). Both are active, ROHS3 compliant, and support -55°C ~ 175°C operating temperature.

Q: Can I use a higher power-rated part like 15KPA36A-HR as a substitute?

A: Yes, provided physical space accommodates the P600 package. The 15KPA36A-HR maintains the 36V reverse standoff voltage and is functionally compatible. The 15000W peak pulse power rating provides enhanced transient suppression compared to the 1N6380's 1500W rating. This is suitable for applications requiring increased surge handling capability.

Q: What are the package differences between substitute parts?

A: The 1N6380 uses DO-201AD axial package. Equivalent parts use: DO-201AA/DO-27 (LCE36A), DO-204AC/DO-15 (P5KE36A series), R-6 (5KP36A-G), and P600 (5KP36A-HR/HRA, 15KPA36A series, 30KPA36A series). All are through-hole axial configurations. Package selection depends on PCB layout constraints and available mounting space.

Q: Are all substitute parts RoHS compliant?

A: Most active substitutes are ROHS3 compliant (LCE36A, 5KP36A-G, 5KP36A-HR/HRA, 15KPA36A series, 30KPA36A series). The P5KE36A-AP and P5KE36A-BP do not specify RoHS status in the provided data. The original 1N6380 is RoHS non-compliant.

Q: What is the temperature range consideration for substitute selection?

A: The 1N6380 operates from -65°C ~ 175°C. Most substitutes support -55°C ~ 175°C (Littelfuse 5KP and KPA series, P5KE series) or -65°C ~ 175°C (LCE36A, P5KE series). The 5KP36A-G from Comchip operates -55°C ~ 150°C, which is narrower. Verify application temperature requirements before selection.

Q: Can I use P5KE36A parts as direct replacements?

A: P5KE36A-AP and P5KE36A-BP are functionally compatible but have reduced power rating (500W versus 1500W). They are suitable only for applications where lower transient energy is acceptable. The DO-15 package is more compact than DO-201AD, making these parts useful for space-constrained designs with lower surge requirements.
