Product details
Overview
JANTXV1N6163US/TR from Microsemi is a military-qualified, voidless hermetically sealed, bidirectional Transient Voltage Suppressor (TVS) in SQ-MELF package. It provides 56.0 V working standoff voltage (VWM), 71.3 V minimum breakdown voltage (V(BR)), 103.1 V clamping voltage (VC) at 14.5 A peak pulse current (IPP), and 1500 W peak pulse power for 10/1000 µs waveform - deployed in avionics power rail protection.
For engineers reviewing the JANTXV1N6163US/TR datasheet, JANTXV1N6163US/TR pinout, JANTXV1N6163US/TR application, or JANTXV1N6163US/TR equivalent, key selection criteria include MIL-PRF-19500/516 JANTXV qualification, bidirectional surge suppression capability, glass-body thermal resistance (5.0 °C/W), and compatibility with high-reliability ESD/EFT/IEC61000-4-5 secondary lightning protection requirements.
Technical Context
This TVS operates bidirectionally with no polarity marking and uses internal Category 1 metallurgical bonds for radiation-hardened reliability per MicroNote 050. Its hard-glass construction ensures voidless hermetic sealing and immunity to MIL-STD-750 Method 1020 ESD stress.
Rated for -55 °C to +175 °C junction temperature, it delivers stable clamping performance across military thermal extremes. The 5.0 °C/W junction-to-end-cap thermal resistance supports robust power dissipation during repetitive transients when mounted on thermally managed PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 56.0 V - maximum continuous DC or repetitive peak reverse voltage before conduction begins |
| V(BR) min | 71.3 V @ 20 mA - guaranteed minimum breakdown threshold under specified test current |
| VC @ IPP | 103.1 V @ 14.5 A - clamped voltage during 10/1000 µs transient, defining worst-case overvoltage seen by protected circuit |
| PPP | 1500 W - peak impulse power handling for standardized 10/1000 µs waveform, enabling robust lightning surge immunity |
| ID @ VWM | 5 µA - leakage current at rated standoff voltage, ensuring minimal standby power loss in high-impedance circuits |
| αV(BR) | 0.100 %/°C - temperature coefficient of breakdown voltage, critical for stability across -55 °C to +175 °C operating range |
| RθJEC | 5.0 °C/W - junction-to-end-cap thermal resistance, enabling accurate thermal design for pulsed power dissipation |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6163US/TR | Commercial-grade version; same VWM (56.0 V), VC (103.1 V), and IPP (14.5 A), but not MIL-PRF-19500/516 qualified | Lacks JANTXV screening; unsuitable for programs requiring traceable military reliability testing | Select only for cost-sensitive non-military designs where full MIL-spec screening is unnecessary |
| JANTXV1N6162US/TR | Lower VWM (51.7 V), lower VC (97.1 V), higher IPP (15.4 A); otherwise identical package, qualification, and construction | Better suited for 24 V nominal systems requiring tighter clamping margin below 100 V | Choose when protecting 24 V rails where lower clamping voltage reduces stress on downstream 100 V-rated components |
Compared with JANTXV1N6163US/TR, the commercial 1N6163US/TR omits military screening but retains identical electrical specs, while JANTXV1N6162US/TR offers lower clamping for 24 V systems - enabling precise voltage-tiered protection architecture without changing layout or thermal design.

FAQ
What is the clamping voltage of JANTXV1N6163US/TR and how is it measured?
The clamping voltage of JANTXV1N6163US/TR is 103.1 V, measured at 14.5 A peak pulse current (IPP) under the standardized 10/1000 µs double-exponential transient waveform. This value represents the maximum voltage that will appear across the device during a surge event, directly limiting overvoltage stress on downstream circuitry. The test condition is defined in MIL-STD-750 Method 3019 and confirmed in the official Microsemi T4-LDS-0278-1 datasheet for JANTXV1N6163US/TR.
Is JANTXV1N6163US/TR suitable for bidirectional signal line protection?
Yes, JANTXV1N6163US/TR is inherently bidirectional and requires no polarity marking during placement. Its symmetrical avalanche structure allows it to suppress positive and negative transients equally - making it ideal for protecting AC-coupled data lines (e.g., RS-485, ARINC 429), transformer-isolated interfaces, or floating power domains. This behavior is explicitly confirmed in the "Polarity" section of the T4-LDS-0278-1 datasheet for JANTXV1N6163US/TR.
Does JANTXV1N6163US/TR meet IEC61000-4-5 for lightning surge immunity?
JANTXV1N6163US/TR provides protection against the secondary effects of lightning per select levels of IEC61000-4-5, as stated in the Applications/Benefits section of its official datasheet. Its 1500 W peak pulse power rating at 10/1000 µs aligns with Level 3 and Level 4 combination wave test requirements (e.g., 2 Ω source impedance, 1 kV–4 kV). System-level compliance depends on PCB layout and upstream impedance, but JANTXV1N6163US/TR is a validated first-line defense component for such standards.
What is the thermal resistance specification for JANTXV1N6163US/TR and why does it matter?
JANTXV1N6163US/TR has a junction-to-end-cap thermal resistance (RθJEC) of 5.0 °C/W, measured from the silicon die to the outer surface of either end cap. This parameter is critical for predicting temperature rise during repetitive surge events and verifying safe operation within the -55 °C to +175 °C junction limit. Unlike ambient-based metrics, RθJEC enables accurate thermal modeling when the device is soldered directly to a heatsink or thermally enhanced pad - essential for high-duty-cycle avionics applications.
How does JANTXV1N6163US/TR differ from the commercial 1N6163US/TR variant?
JANTXV1N6163US/TR differs from 1N6163US/TR solely in reliability qualification: it is fully screened to MIL-PRF-19500/516 JANTXV level (including burn-in, temperature cycling, and life test), whereas 1N6163US/TR is commercial-grade with no military screening. Electrically and physically - including VWM (56.0 V), VC (103.1 V), package, and marking - both share identical specifications. The choice depends strictly on program-level reliability and traceability requirements for JANTXV1N6163US/TR.
