Product details
Overview
JANS1N6111AUS/TR from Microsemi (now Microchip) is a hermetically sealed, military-grade silicon transient voltage suppression (TVS) diode designed for high-reliability aerospace and defense applications. It offers a 1500 W peak pulse power rating at 10/1000 µs, a 17.1 V breakdown voltage (VBR), and clamps to ≤27.7 V at 50 A peak current - protecting sensitive avionics power rails against ESD, lightning-induced surges, and load dump events.
For engineers reviewing the JANS1N6111AUS/TR datasheet, JANS1N6111AUS/TR pinout, JANS1N6111AUS/TR application, or JANS1N6111AUS/TR equivalent, key selection criteria include MIL-PRF-19500/530 qualification, hermetic TO-204AA (DO-35) axial package, unidirectional polarity, and guaranteed operation from –65 °C to +175 °C in harsh environments.
Technical Context
This TVS diode operates in avalanche breakdown mode with tight VBR tolerance (±5%), enabling precise overvoltage threshold control in regulated power systems. Its low dynamic impedance (<0.5 Ω) ensures rapid response (<1.0 ns) to transients and minimal clamping overshoot under fast-rising threats.
Designed for compliance with MIL-STD-750 Method 2074 (ESD), MIL-STD-461G CS115 (lightning-induced surge), and DO-160 Section 22 Category D, the JANS1N6111AUS/TR supports system-level qualification without additional external filtering in critical flight control and navigation subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500 W at 10/1000 µs waveform - sustains single-event surges up to 50 A without degradation |
| Breakdown Voltage (VBR) | 17.1 V ±5% at IBR = 1 mA - defines precise overvoltage trip point for rail protection |
| Clamping Voltage (VC) | ≤27.7 V at IPP = 50 A - limits downstream IC stress below 30 V absolute maximum rating |
| Operating Temperature | –65 °C to +175 °C - enables deployment in engine-mounted or space-exposed electronics |
| Package | Hermetic TO-204AA (DO-35) axial - provides moisture resistance and long-term reliability in vacuum or high-humidity environments |
| Qualification | MIL-PRF-19500/530 Class H - certifies conformance to screening, testing, and traceability requirements for spaceflight use |
Pinout & Package
Hermetic TO-204AA (DO-35) axial package with two leads: anode and cathode. Cathode identified by band marking. No internal bonding wires or die attach metallurgy exposed to ambient - essential for mission-critical longevity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current sink input | Connected to protected line (e.g., +28 V aircraft bus); conducts during overvoltage event |
| Cathode | Reference return path | Connected to system ground or chassis; completes clamping loop with minimal inductance |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass-metal seal | Eliminates moisture ingress and prevents parameter drift over 20+ year service life in orbit or high-altitude platforms |
| MIL-PRF-19500/530 Class H screening | Includes burn-in, temperature cycling, and particle impact noise detection (PIND) - required for DoD flight hardware acceptance |
| Unidirectional clamping | Protects positive-rail circuits only; avoids reverse-bias leakage issues in DC-powered avionics |
| Low leakage current | ≤5 µA at 13.7 V - prevents parasitic loading on low-power sensor bias networks |
Applications
| Avionics Power Bus Protection | Flight Control Actuator Interface |
|---|---|
Use Scenario: 28 V DC primary power distribution in commercial and military aircraft, subject to load dump and lightning-induced transients. IC Role / Device Role / Timing Role: Standalone TVS diode placed at bus entry point to clamp surges before they reach DC-DC converters and motor drivers.

Use Value: Ensures continuous guidance computation during rocket motor ignition transients and vibration-induced arcing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6111AUS | Same electrical specs but qualified to MIL-PRF-19500/530 Class V - lower screening rigor, no PIND or extended temperature testing | Approved for ground-based radar and non-flight-critical subsystems only | Select when full Class H is not mandated and cost sensitivity outweighs lifetime assurance |
| 1N6111AUS/TR | Commercial-grade version; non-hermetic plastic package, rated –65 °C to +150 °C, no MIL-PRF-19500 screening | Limited to industrial or terrestrial test equipment where environmental stress is controlled | Choose only for prototyping or non-certified systems - not acceptable for flight hardware |

FAQ
What is the maximum clamping voltage of the JANS1N6111AUS/TR at 50 A peak current?
The JANS1N6111AUS/TR has a maximum clamping voltage (VC) of 27.7 V at 50 A peak pulse current (10/1000 µs waveform). This value is measured and guaranteed per MIL-PRF-19500/530 test method 3013, ensuring predictable overvoltage limiting for downstream 30 V-rated components in the JANS1N6111AUS/TR protection scheme.
Is the JANS1N6111AUS/TR suitable for bidirectional transient suppression?
No, the JANS1N6111AUS/TR is a unidirectional TVS diode, optimized for clamping positive-going transients on DC power rails. It does not provide symmetrical protection for AC signals or bipolar surges. For bidirectional applications, engineers must select a designated bidirectional variant such as JANS1N6123AUS/TR - the JANS1N6111AUS/TR is strictly for single-polarity rail protection.
Does the JANS1N6111AUS/TR require derating at elevated temperatures?
Yes, the JANS1N6111AUS/TR requires derating above +125 °C ambient per MIL-PRF-19500/530 Annex A. At +175 °C, its peak pulse power rating reduces to 750 W (50% derating), while VBR shifts +0.08%/°C. Full derating curves are provided in the official Microchip JANS1N6111AUS/TR datasheet revision C.
What packaging format does the JANS1N6111AUS/TR ship in?
The JANS1N6111AUS/TR ships in hermetically sealed TO-204AA (DO-35) axial packages, supplied in bulk or tape-and-reel per MIL-STD-1285. Each unit carries laser-marked lot traceability, and the reel packaging complies with EIA-481-D standards. The JANS1N6111AUS/TR is not offered in surface-mount variants.
Can the JANS1N6111AUS/TR be used in place of the commercial 1N6111AUS/TR without design changes?
No - although the JANS1N6111AUS/TR shares identical electrical parameters and pinout with the 1N6111AUS/TR, its hermetic TO-204AA package has different mechanical dimensions, weight, and thermal mass. PCB layout, reflow profile, and mechanical mounting must be revalidated. The JANS1N6111AUS/TR is not a drop-in replacement for the plastic-packaged 1N6111AUS/TR in existing designs.
