Product details
Overview
JANTX1N6118AUS/TR from Microsemi (now part of Microchip Technology) is a military-grade 150 V, 5 W transient voltage suppression (TVS) diode in a hermetically sealed DO-213AA (GLASS) package, featuring 150 V standoff voltage, 170 V breakdown voltage, and 24.2 A peak pulse current (8/20 µs), used for surge protection in avionics power rails.
For engineers reviewing the JANTX1N6118AUS/TR datasheet, JANTX1N6118AUS/TR pinout, JANTX1N6118AUS/TR application, or JANTX1N6118AUS/TR equivalent, key selection criteria include clamping voltage at rated current, MIL-PRF-19500/530 qualification, unidirectional polarity, and glass-passivated junction reliability under thermal cycling.
Technical Context
This unidirectional TVS diode operates as a clamping device in parallel with sensitive circuitry, responding to transients within <1 ps. Its glass-passivated junction ensures stable leakage current (<1 µA at 120 V) and low capacitance (≤100 pF), critical for high-speed analog signal integrity in radar front-ends.
Qualified per MIL-PRF-19500/530, the JANTX1N6118AUS/TR supports operation from –65 °C to +175 °C and meets stringent screening including burn-in, temperature cycling, and hermeticity testing-enabling use in flight-critical subsystems where failure modes must be precluded.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage | 150 V - Maximum continuous reverse operating voltage before conduction begins |
| Breakdown Voltage | 170 V (min) - Voltage at which device enters avalanche conduction under specified test current |
| Clamping Voltage | 246 V @ 24.2 A (8/20 µs) - Peak voltage seen by protected circuit during worst-case surge |
| Peak Pulse Power | 5000 W - Maximum non-repetitive surge energy absorption capability |
| Leakage Current | <1 µA @ 120 V - Ensures minimal loading on high-impedance bias networks |
| Capacitance | ≤100 pF @ 0 V - Preserves signal fidelity in RF and timing-sensitive circuits |
Pinout & Package
Package: DO-213AA (GLASS), hermetically sealed, axial-leaded, 2-terminal device with cathode band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to ground or lower-potential rail in unidirectional clamp configuration |
| Cathode | Current exit point during forward conduction; marked with band | Connected to protected line; conducts avalanche current to anode during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/530 Qualified | Meets full military screening including 100% lot acceptance testing and hermeticity verification |
| Hermetic Glass Package | Eliminates moisture ingress risk and enables reliable operation at 175 °C ambient |
| Low Clamping Ratio | Clamping voltage is only 1.45× breakdown voltage - minimizes stress on downstream ICs |
| Fast Response Time | <1 ps - Limits transient energy penetration before clamping activates |
Applications
| Avionics Power Distribution | Radar Receiver Front-End |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6118AUS/TR | Higher screening level (JANTXV vs JANTX); includes additional radiation hardness assurance and extended temperature validation | Required for space-qualified payloads and nuclear-hardened platforms | Select JANTXV1N6118AUS/TR only when radiation tolerance or extended qualification beyond MIL-PRF-19500/530 is mandated |
| 1N6118US | Commercial-grade version; not MIL-qualified; no hermetic seal; wider parametric tolerances | Suitable for ground-based test equipment or non-safety-critical industrial controls | Use 1N6118US only in cost-sensitive, non-military environments where screening and hermeticity are not required |
Compared with JANTXV1N6118AUS/TR, the JANTX1N6118AUS/TR offers full MIL-PRF-19500/530 compliance at lower cost and weight, while the commercial 1N6118US lacks screening and environmental robustness-making JANTX1N6118AUS/TR the optimal balance for certified avionics hardware.

FAQ
What is the maximum clamping voltage of the JANTX1N6118AUS/TR under standard surge conditions?
The JANTX1N6118AUS/TR has a maximum clamping voltage of 246 V when subjected to a 24.2 A peak pulse current with an 8/20 µs waveform. This value is measured per MIL-STD-883 Method 3012 and defines the upper voltage limit imposed on protected circuitry during transient events.
Is the JANTX1N6118AUS/TR qualified to MIL-PRF-19500/530?
Yes, the JANTX1N6118AUS/TR is fully qualified to MIL-PRF-19500/530, including mandatory tests such as hermeticity, temperature cycling, burn-in, and lot acceptance testing. This qualification confirms its suitability for use in military and aerospace applications governed by strict reliability standards.
What is the operating temperature range for the JANTX1N6118AUS/TR?
The JANTX1N6118AUS/TR operates across –65 °C to +175 °C, validated per MIL-PRF-19500/530. This extended range supports deployment in engine-mounted electronics, radar housings, and other high-thermal-stress locations where commercial TVS devices would fail.
Does the JANTX1N6118AUS/TR have unidirectional or bidirectional polarity?
The JANTX1N6118AUS/TR is a unidirectional TVS diode, designed for DC or single-polarity signal line protection. Its cathode band identifies the terminal connected to the protected line, and it conducts only during reverse overvoltage events-making it ideal for 28 V and 270 V avionics power rails.
What package type does the JANTX1N6118AUS/TR use, and why is it significant?
The JANTX1N6118AUS/TR uses a hermetically sealed DO-213AA (GLASS) package. This construction prevents moisture ingress and enables stable performance at 175 °C ambient-critical for long-term reliability in sealed avionics enclosures where condensation or thermal cycling could compromise plastic-packaged alternatives.
