PTVS6-380C-TH Equivalent & Substitute Parts

Part Overview

The PTVS6-380C-TH is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection applications. This bidirectional zener diode operates with a reverse standoff voltage of 380V and provides clamping at 520V with a peak pulse current rating of 6000A (8/20µs). The part is currently active in production and widely stocked. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Parameter Comparison

Engineering Selection Recommendations

All three parts—PTVS6-380C-TH, AK6-380C, and AK6-380C-BP—are active products with ROHS3 compliance and equivalent electrical specifications for the critical parameters: reverse standoff voltage, breakdown voltage, clamping voltage, and peak pulse current.

PTVS6-380C-TH (Bourns Inc.): Primary choice with established inventory (1076 pcs). REACH Affected status applies.

AK6-380C (Littelfuse): Direct substitute with superior inventory availability (500100 pcs). REACH Unaffected status. Operating temperature range matches the primary part. Packaging is Tray.

AK6-380C-BP (Micro Commercial Co): Direct substitute with extended operating temperature range (-55°C ~ 150°C). Bulk packaging. REACH Unaffected status. Inventory: 1053 pcs.

Selection between these parts depends on supply availability, packaging requirements (Tray vs. Bulk), and operating temperature requirements. All three parts are electrically interchangeable for applications within the -55°C ~ 125°C range.

Frequently Asked Questions (FAQ)

Q: Can AK6-380C replace PTVS6-380C-TH in my circuit?

A: Yes. Both parts share identical electrical specifications for reverse standoff voltage (380V), breakdown voltage (401V), clamping voltage (520V), and peak pulse current (6000A). Both are through-hole axial components with the same package dimensions (24.15mm center). Operating temperature ranges are equivalent at -55°C ~ 125°C.

Q: What is the difference between AK6-380C and AK6-380C-BP?

A: The primary differences are packaging and operating temperature range. AK6-380C is supplied in Tray packaging, while AK6-380C-BP is supplied in Bulk packaging. AK6-380C-BP supports an extended operating temperature range of -55°C ~ 150°C compared to -55°C ~ 125°C for AK6-380C. Electrical specifications are identical.

Q: Are there any compliance differences between these parts?

A: All three parts are ROHS3 compliant. PTVS6-380C-TH is REACH Affected, while both AK6-380C and AK6-380C-BP are REACH Unaffected. ECCN and HTSUS classifications are identical across all three parts.

Q: Which part should I select if my application operates above 125°C?

A: AK6-380C-BP is the appropriate choice, as it supports operating temperatures up to 150°C (TJ). PTVS6-380C-TH and AK6-380C are rated to 125°C maximum.

Q: Do these parts have the same capacitance characteristics?

A: Capacitance values differ. PTVS6-380C-TH specifies 650pF @ 10kHz, while AK6-380C specifies 1400pF @ 10kHz. AK6-380C-BP does not provide a capacitance specification. Verify capacitance requirements for your specific application before selection.
