Product details
Overview
JANS1N6163AUS/TR from Microsemi is a voidless hermetically sealed, bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANS reliability level. It provides 56.0 V working standoff voltage (VWM), 71.3 V minimum breakdown voltage (V(BR)) at 20 mA, 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 aerospace power bus protection and avionics interface circuits.
For engineers reviewing the JANS1N6163AUS/TR datasheet, JANS1N6163AUS/TR pinout, JANS1N6163AUS/TR application, or JANS1N6163AUS/TR equivalent, key selection criteria include its JANS-level military qualification, bidirectional clamping behavior, 103.1 V VC under 14.5 A surge, -55°C to +175°C operating junction temperature range, and SQ-MELF "C" package compatibility with automated surface-mount assembly.
Technical Context
This device operates as a bidirectional avalanche diode-based TVS, leveraging hard-glass hermetic construction with internal Category 1 metallurgical bonds to ensure radiation hardness and long-term reliability in high-reliability environments. Its clamping action begins at V(BR) ≥71.3 V and limits transient energy to ≤103.1 V across the protected line when subjected to 14.5 A (10/1000 µs).
The JANS1N6163AUS/TR exhibits a temperature coefficient of breakdown voltage (αV(BR)) of 0.100 %/°C and supports steady-state off-state power dissipation up to 3.0 W at 25 °C ambient, derating linearly to zero at 175 °C junction temperature. Thermal resistance from junction to end cap is 5.0 °C/W, enabling effective heat transfer in constrained board layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 56.0 V - maximum continuous reverse standoff voltage before conduction begins; defines safe operating margin below clamping threshold. |
| V(BR) min | 71.3 V @ 20 mA - guaranteed avalanche onset voltage; ensures predictable turn-on during overvoltage events. |
| VC @ IPP | 103.1 V @ 14.5 A - clamped voltage during 10/1000 µs surge; determines maximum stress on downstream circuitry. |
| PPP | 1500 W - peak pulse power rating for 10/1000 µs waveform; quantifies transient energy absorption capability. |
| TJ Range | -55°C to +175°C - operational junction temperature range; supports deployment in extreme environmental conditions. |
| RθJEC | 5.0 °C/W - thermal resistance from junction to end cap; enables direct thermal path design into metal-core PCBs or heatsinks. |
| ID @ VWM | 5 µA - maximum leakage current at rated standoff voltage; ensures minimal standby power loss and signal integrity. |
Pinout & Package
Package: SQ-MELF "C" (hermetically sealed voidless hard glass with tungsten slugs; tin/lead-plated copper terminals; no polarity marking; weight ≈1100 mg).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Transient conduction path | No designated anode/cathode; symmetric bidirectional clamping allows placement without orientation constraints. |
| End Cap (both ends) | Thermal and mechanical interface | Direct thermal path to PCB pad or heatsink; requires full-surface solder contact for rated RθJEC = 5.0 °C/W. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6163AUS (commercial) | No JANS qualification; same electrical specs but not tested to MIL-PRF-19500/516 screening requirements. | Suitable for non-mission-critical industrial prototypes where cost and lead time outweigh radiation hardness needs. | Select only if JANS-level screening, burn-in, and lot traceability are not required. |
| JANS1N6162AUS/TR | Lower VWM (51.7 V), lower VC (97.1 V), higher IPP (15.4 A); identical package and qualification level. | Better suited for 24–48 V systems needing tighter clamping margin below 100 V. | Choose when system nominal voltage is ≤48 V and clamping headroom must be minimized. |
Compared with JANS1N6163AUS/TR, the commercial 1N6163AUS lacks military screening but offers identical electrical performance, while JANS1N6162AUS/TR trades 4.3 V higher VWM for improved clamping headroom in lower-voltage rails - both require revalidation of surge margin and thermal layout.

FAQ
What is the maximum clamping voltage of JANS1N6163AUS/TR under standard test conditions?
The JANS1N6163AUS/TR has a maximum clamping voltage (VC) of 103.1 V when subjected to a 10/1000 µs surge current pulse of 14.5 A, as specified in the Microsemi T4-LDS-0278-1 datasheet. This value is measured at the device terminals with proper PCB layout and thermal mounting, and defines the upper voltage limit imposed on protected circuitry during transient events. The JANS1N6163AUS/TR maintains this clamping performance across its full -55°C to +175°C junction temperature range.
Is JANS1N6163AUS/TR compatible with lead-free reflow processes?
JANS1N6163AUS/TR is rated for a maximum solder temperature of 260°C for 10 seconds, making it compatible with standard SnAgCu lead-free reflow profiles. However, its terminations are tin/lead plated per the datasheet, so full RoHS compliance requires the commercial-grade e3-marked variant. The JANS1N6163AUS/TR itself is not RoHS compliant but remains suitable for legacy aerospace assemblies using Pb-based soldering processes.
Does JANS1N6163AUS/TR have polarity markings, and how should it be oriented during placement?
No - JANS1N6163AUS/TR is a bidirectional TVS with no polarity markings, as confirmed in the "MECHANICAL and PACKAGING" section of the datasheet. Its symmetrical construction allows placement in either orientation on the PCB without affecting clamping performance. This eliminates orientation errors during automated placement and simplifies layout for differential or AC-coupled signal lines.
What is the temperature coefficient of breakdown voltage for JANS1N6163AUS/TR?
The temperature coefficient of breakdown voltage (αV(BR)) for JANS1N6163AUS/TR is 0.100 %/°C, meaning its V(BR) increases by approximately 0.071 V per °C rise in junction temperature (based on 71.3 V nominal). This parameter is critical for predicting clamping behavior across wide temperature ranges in aerospace applications, and is verified per MIL-PRF-19500/516 test requirements for the JANS grade.
How does JANS1N6163AUS/TR differ from the non-A suffix version (e.g., JANS1N6163US/TR)?
The "A" suffix in JANS1N6163AUS/TR indicates tighter voltage tolerances: it guarantees minimum V(BR) ≥71.3 V, whereas the non-A version has 5% lower minimum V(BR), 5% higher VC, and 5% lower IPP. This makes JANS1N6163AUS/TR more predictable in clamping threshold and energy handling - essential for deterministic protection design in safety-critical systems where margin analysis must be precise.
