1N6476US Equivalent & Substitute Parts

Part Overview

The 1N6476US is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose transient protection applications. This surface-mount component features a 51.6V reverse standoff voltage with a maximum clamping voltage of 78.5V and peak pulse current handling of 107A (8/20µs). The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement requirements.

Substitute Part Grouping Explanation

Substitution of the 1N6476US is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for voltage protection characteristics (reverse standoff, breakdown, and clamping voltages), current handling capacity, power dissipation rating, operating temperature range, and physical package configuration. The JANTXV1N6476US qualifies as a direct substitute based on complete parameter alignment across these criteria. This part shares the same base product number (1N6476) and maintains all electrical performance specifications while offering enhanced qualification status through military-grade certification.

Key Parameters for Substitution:

• Voltage - Reverse Standoff: 51.6V
• Voltage - Clamping (Max) @ Ipp: 78.5V
• Current - Peak Pulse: 107A (8/20µs)
• Power - Peak Pulse: 1500W
• Package: G-MELF (D-5C)
• Operating Temperature: -55°C to 175°C

Parameter Comparison

Engineering Selection Recommendations

The JANTXV1N6476US serves as the direct equivalent substitute for the discontinued 1N6476US. Both parts are manufactured by Microchip Technology and share identical electrical specifications and physical packaging. The JANTXV1N6476US maintains active product status with confirmed inventory availability, addressing the procurement limitation of the original part number.

The JANTXV1N6476US carries military-grade qualification under MIL-PRF-19500/552, providing enhanced reliability assurance compared to the commercial-grade 1N6476US. This qualification status does not alter the electrical or mechanical performance characteristics but indicates stricter manufacturing and testing protocols. Selection of the JANTXV1N6476US is appropriate for applications requiring either military-grade components or where the original part number is no longer available through standard distribution channels.

Both parts maintain identical RoHS non-compliance status and REACH unaffected classification, requiring equivalent compliance consideration in procurement and design documentation.

Frequently Asked Questions (FAQ)

Q: Can the JANTXV1N6476US directly replace the 1N6476US without circuit modification?

A: Yes. The JANTXV1N6476US is electrically and mechanically identical to the 1N6476US across all specified parameters. No circuit modifications are required for direct substitution.

Q: What is the difference between the 1N6476US and JANTXV1N6476US?

A: The primary difference is product status and qualification level. The JANTXV1N6476US is an active military-grade part qualified to MIL-PRF-19500/552, while the 1N6476US is a discontinued commercial-grade part. Electrical performance and package specifications are identical.

Q: Are there any package compatibility concerns when substituting these parts?

A: No. Both parts use the identical G-MELF (D-5C) surface-mount package configuration. PCB footprints and assembly processes remain unchanged.

Q: Why is the 1N6476US discontinued?

A: The provided data indicates discontinuation at DiGi Electronics. The JANTXV1N6476US remains in active production and is the recommended alternative for ongoing procurement.

Q: Does the military qualification of JANTXV1N6476US affect its performance in commercial applications?

A: No. Military qualification indicates enhanced manufacturing and testing standards but does not alter electrical or mechanical performance. The JANTXV1N6476US performs identically to the 1N6476US in all applications.

Q: What is the operating temperature range for both parts?

A: Both the 1N6476US and JANTXV1N6476US operate across -55°C to 175°C junction temperature range.

Q: Are there RoHS compliance considerations for these parts?

A: Both parts are RoHS non-compliant. Equivalent compliance documentation and procurement considerations apply to both part numbers.
