AK6-380C Equivalent & Substitute Parts

Part Overview

The AK6-380C is a bidirectional Zener transient voltage suppressor (TVS) diode manufactured by Littelfuse, designed for general-purpose overvoltage protection applications. This through-hole axial component features a 380V reverse standoff voltage with 520V maximum clamping voltage and 6000A peak pulse current capability. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options while maintaining equivalent electrical and mechanical performance characteristics.

Substitute Part Grouping Explanation

Substitution eligibility for the AK6-380C is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 380V
• Voltage - Breakdown (Min): 401V
• Voltage - Clamping (Max) @ Ipp: 520V
• Current - Peak Pulse (10/1000µs): 6000A (6kA) (8/20µs)
• Bidirectional Channels: 1
• Type: Zener
• Mounting Type: Through Hole
• Package / Case: Axial, Right Angle Bend (24.15mm Center)

The substitute part AK6-380C-BP, manufactured by Micro Commercial Co, meets all critical electrical parameters and maintains identical mechanical form factor and mounting specifications. Both parts share the same base product designation (AK6-380) and are cross-referenced within manufacturer documentation.

Parameter Comparison

Engineering Selection Recommendations

Both the AK6-380C and AK6-380C-BP are active production components with full regulatory compliance. Selection between these parts is based on availability, packaging preference, and application temperature requirements. The AK6-380C-BP offers an extended operating temperature range to 150°C compared to the primary part's 125°C maximum, providing additional thermal margin in high-temperature environments. Both parts maintain identical electrical performance, mechanical form factor, and compliance certifications (RoHS3, REACH Unaffected). Packaging differs between tray (primary part) and bulk (substitute), which may influence procurement and handling procedures but does not affect functional equivalence.

Frequently Asked Questions (FAQ)

Q: Are the AK6-380C and AK6-380C-BP electrically interchangeable?

A: Yes. Both parts share identical voltage ratings (380V reverse standoff, 520V clamping), peak pulse current (6000A), and bidirectional channel configuration. Electrical performance is equivalent across all specified parameters.

Q: What is the difference between tray and bulk packaging?

A: Packaging format affects storage, handling, and procurement logistics but does not impact component performance or functionality. Tray packaging provides organized component arrangement, while bulk packaging offers cost efficiency for high-volume applications.

Q: Can the AK6-380C-BP be used in applications requiring -55°C to 125°C operation?

A: Yes. The AK6-380C-BP operates across -55°C to 150°C, which encompasses the -55°C to 125°C range of the primary part. The extended upper temperature limit provides additional operational margin.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the AK6-380C and AK6-380C-BP are RoHS3 compliant with REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: What determines substitution eligibility for TVS diodes in this category?

A: Substitution is based on matching reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current rating, channel configuration, and mechanical form factor. All these parameters must align for functional equivalence in overvoltage protection circuits.
