Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1N6471US are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

Electrical Parameters (Must Match):

• Voltage - Reverse Standoff (Typ): 12V
• Voltage - Breakdown (Min): 13.6V
• Voltage - Clamping (Max) @ Ipp: 22.6V
• Current - Peak Pulse (10/1000µs): 374A (8/20µs)
• Power - Peak Pulse: 1500W (1.5kW)
• Operating Temperature Range: -55°C to 175°C (TJ)

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package / Case: SQ-MELF, G
• Supplier Device Package: G-MELF (D-5C)

Functional Parameters (Must Match):

• Type: Zener
• Unidirectional Channels: 1
• Applications: General Purpose

Substitute parts may differ in product grade (commercial versus military), qualification standards, and inventory availability, provided all electrical and mechanical parameters remain identical.

Engineering Selection Recommendations

1N6471US (Commercial Grade)

The 1N6471US is suitable for general-purpose transient voltage suppression applications where commercial-grade components are acceptable. This part carries active product status and maintains standard RoHS non-compliant and REACH Unaffected compliance posture. Selection of this part is appropriate for applications without military qualification requirements.

JANTXV1N6471US (Military Grade)

The JANTXV1N6471US is the military-qualified equivalent of the 1N6471US, qualified to MIL-PRF-19500/552 specification. This part is selected for applications requiring military-grade components, enhanced reliability screening, or compliance with military procurement standards. The JANTXV1N6471US maintains identical electrical and mechanical parameters to the commercial 1N6471US while providing military-grade qualification and higher inventory availability (1123 pieces versus 703 pieces).

Both parts are manufactured by Microchip Technology, carry active product status, and are functionally interchangeable within the specified electrical and mechanical parameters. Selection between these parts depends on application requirements for commercial versus military-grade qualification.

Frequently Asked Questions (FAQ)

Q: Can the JANTXV1N6471US be used as a direct replacement for the 1N6471US?

A: Yes. The JANTXV1N6471US is a direct substitute for the 1N6471US. Both parts share identical electrical parameters (12V reverse standoff, 13.6V breakdown minimum, 22.6V clamping maximum, 374A peak pulse current, 1500W peak pulse power), identical operating temperature range (-55°C to 175°C), and identical mechanical packaging (G-MELF surface mount). The JANTXV1N6471US carries military-grade qualification to MIL-PRF-19500/552, whereas the 1N6471US is commercial grade.

Q: What is the difference between the 1N6471US and JANTXV1N6471US?

A: The primary difference is product grade and qualification. The 1N6471US is a commercial-grade TVS diode. The JANTXV1N6471US is the military-qualified variant of the same part, qualified to MIL-PRF-19500/552 specification. All electrical and mechanical specifications are identical. The JANTXV1N6471US also has higher inventory availability.

Q: Are both parts suitable for the same circuit applications?

A: Yes. Both the 1N6471US and JANTXV1N6471US are suitable for identical general-purpose transient voltage suppression applications. The choice between them depends on whether military-grade qualification is required by the application specification or procurement standard.

Q: What is the G-MELF package?

A: The G-MELF package is a surface mount package designation (SQ-MELF, G) with supplier device package code G-MELF (D-5C). Both substitute parts use this identical package, ensuring mechanical and thermal compatibility in PCB layouts and reflow soldering processes.

Q: Can these parts be used in power line protection applications?

A: No. Both the 1N6471US and JANTXV1N6471US are designated for general-purpose applications and do not carry power line protection capability.

Q: What is the moisture sensitivity level for these parts?

A: Both parts carry Moisture Sensitivity Level (MSL) 1, which indicates unlimited moisture sensitivity—no special moisture control measures are required during storage or handling.

Q: Are these parts RoHS compliant?

A: No. Both the 1N6471US and JANTXV1N6471US are RoHS non-compliant. Both parts carry REACH Unaffected status and are classified under ECCN EAR99 with HTSUS code 8541.10.0080.
