Product details
Overview
JANS1N6160US/TR from Microsemi is a hermetically sealed, voidless, bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANS level for space and defense applications. It features a 42.6 V working peak standoff voltage (VWM), 77.0 V clamping voltage (VC) at 19.5 A peak pulse current (IPP), and 1500 W peak pulse power (PPP) for 10/1000 µs waveform.
For engineers reviewing the JANS1N6160US/TR datasheet, JANS1N6160US/TR pinout, JANS1N6160US/TR application, or JANS1N6160US/TR equivalent, key selection criteria include military-grade reliability, bidirectional ESD/EFT/IEC61000-4-5 secondary lightning protection capability, hard-glass package robustness, and thermal resistance of 5.0 °C/W junction-to-end cap.
Technical Context
This JANS-level TVS operates bidirectionally with no polarity marking and uses internal Category 1 metallurgical bonds for radiation-hardened, high-reliability performance in harsh environments. Its voidless hermetic glass construction ensures long-term stability under thermal cycling and vacuum exposure.
The device delivers 1500 W peak pulse power at 25 °C with linear derating above 150 °C end-cap temperature, and supports IEC61000-4-2 (ESD), -4-4 (EFT), and select levels of -4-5 (lightning surge) protection. Standby current is ≤5 µA at VWM = 42.6 V.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6160US | Same electrical specs but qualified to JANTXV level; lower screening rigor than JANS; no radiation hardness validation | Suitable for ground-based military systems where full space qualification is not required | Select when cost and lead time are prioritized over TID tolerance and extended temperature lifetime validation |
| 1N6160AUS | Commercial-grade version; lacks MIL-PRF-19500/516 qualification; RoHS-compliant matte-tin plating available | Applicable only in non-safety-critical commercial aerospace or industrial prototypes | Choose only for early-stage design validation where JANS-level reliability is not yet mandated |
Compared with JANS1N6160US/TR, JANTXV1N6160US offers faster procurement and reduced cost but omits radiation hardness verification and extended temperature lifecycle testing, while 1N6160AUS provides RoHS compliance and lower unit price at the expense of military screening and hermeticity assurance.

FAQ
What is the clamping voltage of JANS1N6160US/TR and how is it measured?
The clamping voltage (VC) of JANS1N6160US/TR is 77.0 V, measured at 19.5 A peak pulse current (IPP) using a standardized 10/1000 µs double-exponential waveform. This value represents the maximum voltage seen across the device during surge conduction and is critical for ensuring downstream circuit protection margins. The JANS1N6160US/TR maintains this VC specification across its full qualified temperature range and after MIL-PRF-19500/516 screening.
Is JANS1N6160US/TR unidirectional or bidirectional, and does it require polarity-aware PCB layout?
JANS1N6160US/TR is a bidirectional TVS with no polarity marking on the SQ-MELF package. It conducts equally in both directions once the breakdown voltage is exceeded, making it ideal for AC-coupled or floating signal paths. No polarity-aware layout is needed-either end may connect to either side of the protected line, simplifying routing in high-density aerospace PCBs.
What does "JANS" qualification mean for JANS1N6160US/TR, and how does it differ from commercial versions?
"JANS" qualification means JANS1N6160US/TR meets the highest reliability tier of MIL-PRF-19500/516, including full lot acceptance testing, radiation hardness assurance per MicroNote 050, extended temperature lifetime validation, and 100% electrical screening. Unlike commercial 1N6160AUS, JANS1N6160US/TR undergoes hermeticity leak testing, thermal shock cycling, and radiation exposure verification-mandatory for flight-critical systems.
Can JANS1N6160US/TR be used for IEC61000-4-5 lightning surge protection?
Yes, JANS1N6160US/TR is explicitly rated for protection against the secondary effects of lightning per select levels of IEC61000-4-5. Its 1500 W peak pulse power rating and 77.0 V clamping voltage enable effective suppression of combination wave surges (1.2/50 µs voltage, 8/20 µs current) up to 19.5 A, meeting Level 3 and Level 4 requirements when properly mounted with low-inductance traces and adequate thermal coupling.
What is the thermal resistance specification for JANS1N6160US/TR, and why is it important in system design?
JANS1N6160US/TR has a junction-to-end cap thermal resistance (RθJEC) of 5.0 °C/W. This parameter is essential for calculating safe steady-state power dissipation and transient thermal rise during repeated surges. In high-reliability systems, end-cap soldering to thermally enhanced pads or heatsinks is required to maintain junction temperature below 175 °C-especially critical in sealed enclosures or vacuum environments where convection cooling is absent.
