Product details
Overview
JANTXV1N6166US/TR from Microsemi is a voidless hermetically sealed surface-mount bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANTXV reliability level. It provides 76.0 V working peak standoff voltage (VWM), 137.6 V clamping voltage (VC) at 10.9 A peak pulse current (IPP), and 1500 W peak pulse power for 10/1000 µs waveform - deployed in avionics power bus protection and radar front-end surge suppression.
For engineers reviewing the JANTXV1N6166US/TR datasheet, JANTXV1N6166US/TR pinout, JANTXV1N6166US/TR application, or JANTXV1N6166US/TR equivalent, key selection criteria include military-grade reliability certification, bidirectional clamping behavior, glass-body thermal resistance (5.0 °C/W), and compatibility with high-energy lightning-induced transients per IEC61000-4-5.
Technical Context
This TVS operates as a bidirectional voltage-clamping device with no polarity marking, relying on symmetrical avalanche breakdown in both directions. Its hard-glass construction incorporates internal Category 1 metallurgical bonds and triple-layer passivation to ensure robustness under repeated surge stress and radiation-hardened operation per MicroNote 050.
It delivers 1500 W peak pulse power at 25 °C for 10/1000 µs waveform, with linear derating above 150 °C junction temperature and thermal resistance of 5.0 °C/W from junction to end cap. Standby current remains ≤5 µA at 76.0 V standoff, and clamping occurs at 137.6 V under 10.9 A transient current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 76.0 V - maximum continuous reverse/forward voltage before conduction begins; defines system operating margin before clamping activation. |
| V(BR) min | 95.0 V @ 12 mA - guaranteed minimum breakdown voltage ensures predictable turn-on threshold across temperature and lot variation. |
| VC @ IPP | 137.6 V @ 10.9 A - clamping voltage during 10/1000 µs surge; determines protected circuit's maximum transient overvoltage exposure. |
| PPP | 1500 W - peak pulse power handling capability for standardized lightning-surge waveforms; enables single-device protection of 28 V and 115 V AC/DC military buses. |
| TJ Range | −55 to +175 °C - extended junction temperature range supports operation in engine bay, radar transmitter, and space-qualified electronics. |
| RθJEC | 5.0 °C/W - low thermal resistance from junction to end cap allows efficient heat transfer to PCB copper or heatsink without external thermal vias. |
| IEC Compliance | ESD per IEC61000-4-2, EFT per IEC61000-4-4, lightning secondary effects per IEC61000-4-5 - validated immunity test coverage for MIL-STD-461G platforms. |
Pinout & Package
Package: Hermetically sealed voidless hard-glass "C" package (SQ-MELF style), with tungsten slugs and tin/lead-plated copper terminals. Dimensions: BD = 0.183–0.202 in (4.65–5.13 mm), BL = 0.205–0.245 in (5.21–6.22 mm), ECT = 0.019–0.028 in (0.48–0.71 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Common terminal pair | No polarity marking; symmetric terminals enable identical clamping in either direction - eliminates orientation errors during automated placement. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6166AUS | Commercial-grade version; same VWM (76.0 V), VC (137.6 V), and IPP (10.9 A), but not MIL-qualified or tested to JANTXV screening levels. | Lacks MIL-PRF-19500/516 qualification; unsuitable for DoD contracts requiring traceable reliability data or extended temperature validation. | Select only for non-military prototypes or cost-sensitive commercial derivatives where full JANTXV documentation is not required. |
| JANTXV1N6165US/TR | Lower VWM (69.2 V), lower VC (125.1 V), higher IPP (12.0 A); otherwise identical package, construction, and qualification level. | Better suited for 24 V systems with tighter clamping margin; requires layout review if replacing JANTXV1N6166US/TR in 28 V designs due to reduced standoff headroom. | Use when system VWM must be ≤70 V and clamping voltage budget is constrained below 130 V - verify transient margin with SPICE simulation. |
Compared with 1N6166AUS and JANTXV1N6165US/TR, JANTXV1N6166US/TR uniquely balances 76.0 V standoff with 137.6 V clamping in a JANTXV-qualified glass package - making it optimal for 28 V avionics where both voltage margin and certified reliability are mandatory.

FAQ
What is the clamping voltage of JANTXV1N6166US/TR under a 10/1000 µs surge?
The JANTXV1N6166US/TR has a maximum clamping voltage (VC) of 137.6 V when subjected to a 10.9 A peak pulse current (IPP) with a 10/1000 µs waveform. This value is measured per MIL-STD-750 Method 3013 and is guaranteed across the full −55 to +175 °C operating junction temperature range. The JANTXV1N6166US/TR achieves this clamping performance using symmetrical avalanche breakdown in its voidless hard-glass structure.
Is JANTXV1N6166US/TR RoHS compliant?
No, JANTXV1N6166US/TR is not RoHS compliant. It uses tin/lead plating on copper terminals, consistent with MIL-PRF-19500/516 requirements for high-reliability military applications. RoHS-compliant matte-tin versions are available only in commercial-grade variants (e.g., 1N6166AUS), which lack JANTXV qualification and screening.
Does JANTXV1N6166US/TR have polarity markings?
No, JANTXV1N6166US/TR has no polarity marking because it is a bidirectional TVS. Its symmetrical construction ensures identical clamping behavior in both forward and reverse directions. This eliminates orientation errors during automated placement and simplifies PCB layout - the device may be mounted in either direction without functional impact.
What is the thermal resistance of JANTXV1N6166US/TR?
The thermal resistance from junction to end cap (RθJEC) of JANTXV1N6166US/TR is 5.0 °C/W. This low value results from tungsten slug construction and direct end-cap thermal contact, enabling efficient heat transfer to the PCB during repetitive surge events. Derating follows a linear curve from 100% at 150 °C to zero at 175 °C, per datasheet Figure 4.
How does JANTXV1N6166US/TR differ from JANTXV1N6166US?
JANTXV1N6166US/TR is the tape-and-reel packaging variant of JANTXV1N6166US, conforming to EIA-481-B standards. Both share identical electrical specifications, MIL-PRF-19500/516 qualification, and mechanical construction. The "/TR" suffix denotes automated assembly readiness, while the bare part number refers to bulk or ammo-pack formats - no parametric or reliability differences exist between them.
