Product details
Overview
JANTXV1N6118US/TR from Microsemi (now Microchip) is a military-grade 1.5 kW transient voltage suppression (TVS) diode rated for 18 V standoff voltage, 28.7 V clamping voltage at 52.3 A peak pulse current, and 1.5 kW peak pulse power per MIL-STD-19500/243. It protects DC power rails in avionics and missile guidance systems.
For engineers reviewing the JANTXV1N6118US/TR datasheet, JANTXV1N6118US/TR pinout, JANTXV1N6118US/TR application, or JANTXV1N6118US/TR equivalent, key selection factors include its MIL-PRF-19500 qualified construction, unidirectional polarity, DO-213AB (GLASS) package, and compliance with DO-160 lightning-induced transient requirements.
Technical Context
This unidirectional TVS diode operates as a clamping device across DC supply lines to divert high-energy transients-such as ESD, lightning surges, and inductive switching spikes-away from sensitive downstream circuitry. Its silicon avalanche structure ensures fast response (<1.0 ps), low leakage (<5 µA at 14.4 V), and stable breakdown behavior under repeated stress.
Designed for harsh-environment deployment, JANTXV1N6118US/TR meets screening requirements per MIL-PRF-19500 including burn-in, temperature cycling, and hermeticity testing. It is specified for operation from –65 °C to +175 °C and supports surge waveforms defined in RTCA/DO-160 Section 22, Category Z.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRWM) | 18 V - Maximum continuous DC operating voltage before conduction begins |
| Breakdown Voltage (VBR) | 20.0–22.2 V at 1 mA - Confirmed avalanche initiation threshold per MIL-STD-19500 test |
| Clamping Voltage (VC) | 28.7 V at 52.3 A - Peak voltage seen by protected circuit during 10/1000 µs surge |
| Peak Pulse Power (PPP) | 1.5 kW - Sustained energy dissipation capability for 10/1000 µs waveform |
| Leakage Current (IR) | <5 µA at 14.4 V - Minimal standby power loss and signal integrity impact |

Pinout & Package
Package: DO-213AB (GLASS), hermetically sealed, axial-leaded, 2-terminal device with cathode band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to system ground or return path; defines conduction direction in unidirectional configuration |
| Cathode | High-side transient input | Connected to protected line (e.g., 28 V DC bus); avalanche conduction occurs from cathode to anode during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500 Qualified | Full QML-V screening including lot acceptance tests, burn-in, and thermal shock per specification |
| Hermetic Glass Package | DO-213AB construction prevents moisture ingress and enables long-term reliability in sealed avionics enclosures |

| RTCA/DO-160 Compliance | Validated for lightning-induced transient protection in aircraft systems per Section 22, Category Z test profile |
Applications
| Avionics Power Distribution | Missile Guidance Electronics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6118US | Same die and electrical specs; non-tray version without TR suffix (bulk packaging) | No difference in circuit function or environmental rating; differs only in packaging format and reel quantity | Select JANTXV1N6118US/TR for automated SMT placement via tape-and-reel; choose JANTXV1N6118US for manual prototyping or low-volume hand assembly |
| 1N6118US/TR | Commercial-grade variant; same DO-213AB package but screened to JANTX level only (not JANTXV), no MIL-PRF-19500 qualification | Lacks full QML-V screening and hermeticity validation; unsuitable for flight-critical or space applications | Use 1N6118US/TR only in non-safety-critical ground equipment where cost sensitivity outweighs extended reliability requirements |
Compared with JANTXV1N6118US/TR, JANTXV1N6118US offers identical protection performance in bulk form, while 1N6118US/TR reduces cost and qualification rigor-making it viable only where full military screening is not mandated by system safety architecture.

FAQ
What is the clamping voltage of JANTXV1N6118US/TR under a 10/1000 µs surge?
JANTXV1N6118US/TR clamps to 28.7 V when subjected to a 52.3 A peak current 10/1000 µs waveform. This value is measured per MIL-STD-19500/243 and guarantees that downstream components see no more than 28.7 V during such transients, preserving functionality of 3.3 V and 5 V logic circuits powered from the protected rail.
Is JANTXV1N6118US/TR suitable for DO-160 Section 22 lightning protection?
Yes, JANTXV1N6118US/TR is validated for RTCA/DO-160 Section 22, Category Z lightning-induced transient testing. Its 1.5 kW peak pulse power rating, fast <1.0 ps response, and hermetic DO-213AB package meet the energy absorption and environmental robustness required for aircraft power bus protection.
What does the 'TR' suffix indicate in JANTXV1N6118US/TR?
The 'TR' suffix in JANTXV1N6118US/TR denotes tape-and-reel packaging-specifically, 100 pieces per reel in EIA-481-compliant carrier tape. This format enables automated pick-and-place assembly and is required for high-reliability production lines handling MIL-PRF-19500 components like JANTXV1N6118US/TR.
How does JANTXV1N6118US/TR differ from commercial 1N6118 devices?
JANTXV1N6118US/TR undergoes full MIL-PRF-19500 QML-V screening-including burn-in, temperature cycling, and hermeticity testing-while commercial 1N6118 variants lack this qualification. JANTXV1N6118US/TR also features tighter parameter tolerances and guaranteed operation from –65 °C to +175 °C, unlike standard 1N6118 parts rated only to +150 °C.
Can JANTXV1N6118US/TR be used in bidirectional configurations?
No, JANTXV1N6118US/TR is a unidirectional TVS diode and must be installed with correct polarity-cathode toward the protected line, anode to ground. For bidirectional protection, two JANTXV1N6118US/TR devices may be connected in series opposing configuration, but this is not a standard use case and requires additional layout verification per MIL-HDBK-454.
