PTVS6-380C Equivalent & Substitute Parts

Part Overview

The PTVS6-380C is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection applications. This axial through-hole component features a 380V reverse standoff voltage and 520V clamping voltage with 6000A peak pulse current capability. The product is currently obsolete, making identification of compatible substitute components essential for ongoing system maintenance, repairs, and legacy design support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PTVS6-380C is determined by strict equivalence across the following critical parameters:

• Voltage Rating: Reverse standoff voltage of 380V and breakdown voltage minimum of 401V
• Clamping Performance: Maximum clamping voltage of 520V at peak pulse current
• Peak Pulse Current: 6000A (6kA) capability at 8/20µs pulse duration
• Package Compatibility: Axial through-hole configuration with 24.15mm center spacing
• Electrical Type: Zener-type bidirectional TVS diode with single channel
• Compliance: ROHS3 compliance for environmental standards

The AK6-380C from Littelfuse meets all these substitution criteria, maintaining electrical equivalence while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The AK6-380C is a direct electrical and mechanical substitute for the PTVS6-380C. Both components maintain identical voltage ratings, peak pulse current specifications, and package geometry. The AK6-380C offers the advantage of active product status with significantly higher inventory availability (500,100 pieces versus 690 pieces), ensuring supply chain continuity for new designs and field replacements.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements. The operating temperature range difference (-55°C to 125°C for AK6-380C versus -55°C to 150°C for PTVS6-380C) is not a limiting factor for general-purpose applications within standard industrial temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can the AK6-380C directly replace the PTVS6-380C in existing designs?

A: Yes. Both components share identical voltage ratings (380V standoff, 401V breakdown minimum, 520V clamping), peak pulse current (6000A at 8/20µs), and axial through-hole package geometry with 24.15mm center spacing. No circuit modifications are required.

Q: What is the significance of the operating temperature range difference?

A: The PTVS6-380C operates to 150°C junction temperature, while the AK6-380C operates to 125°C. For applications operating within standard industrial temperature ranges (-40°C to 85°C ambient), this difference is not operationally significant. Applications requiring junction temperatures above 125°C should evaluate specific thermal requirements.

Q: Are there packaging differences between these components?

A: Both components use identical axial through-hole packaging with right-angle bend configuration and 24.15mm center spacing. The PTVS6-380C is supplied in standard packaging, while the AK6-380C is supplied in tray packaging. Both are suitable for through-hole PCB assembly.

Q: Why is the PTVS6-380C obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The AK6-380C from Littelfuse provides equivalent electrical performance with active product status and superior availability for ongoing applications.

Q: What is the difference in capacitance between these parts?

A: The PTVS6-380C has 650pF capacitance at 10kHz, while the AK6-380C has 1400pF at the same frequency. This difference does not affect substitution suitability for general-purpose transient voltage suppression applications, as both values are within acceptable ranges for TVS diode operation.
