Product details
Overview
JANTX1N6117AUS/TR from Microsemi (now Microchip) 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, 243 V maximum clamping voltage at 12.3 A peak pulse current, and <1 ns response time - used for protecting MIL-STD-1275B-compliant 28 V vehicle power bus interfaces.
For engineers reviewing the JANTX1N6117AUS/TR datasheet, JANTX1N6117AUS/TR pinout, JANTX1N6117AUS/TR application, or JANTX1N6117AUS/TR equivalent, key selection criteria include peak pulse power rating, clamping voltage under standardized 10/1000 µs waveform, standoff voltage tolerance, hermetic sealing compliance per MIL-PRF-19500/505, and DO-213AA terminal configuration.
Technical Context
This TVS diode operates as a unidirectional, avalanche-breakdown-based overvoltage protector with specified electrical parameters defined under MIL-PRF-19500/505 Class S screening. Its breakdown voltage is guaranteed between 158 V and 171 V at 1 mA test current, and leakage current remains ≤5 µA at 120 V DC.
The device meets MIL-STD-750 Method 2074 for surge testing and is rated for operation across –65 °C to +175 °C ambient temperature range, with thermal resistance from junction-to-case of 10 °C/W - enabling direct mounting to heat-conductive chassis surfaces in avionics and ground vehicle systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage | 150 V - maximum continuous reverse operating voltage before conduction begins |
| Clamping Voltage | 243 V at 12.3 A (10/1000 µs) - limits transient-induced voltage stress on downstream circuitry |
| Peak Pulse Power | 5000 W - sustains single 10/1000 µs surges up to this energy level without failure |
| Breakdown Voltage Range | 158–171 V at 1 mA - ensures predictable turn-on threshold under MIL-PRF-19500/505 Class S screening |
| Leakage Current | ≤5 µA at 120 V DC - minimizes standby power loss in always-on 28 V bus protection circuits |
| Response Time | <1 ns - enables suppression of fast-rising ESD and lightning-induced transients |
Pinout & Package
Hermetically sealed DO-213AA (GLASS) package with axial leads; cathode indicated by band marking. No internal die bonding wires - glass passivation ensures long-term reliability in high-humidity and radiation-prone environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to system ground or return path; defines conduction polarity during transient events |
| Cathode | High-side protected node | Connected to 28 V supply rail; carries full surge current during clamping operation |

Applications
| Avionics Power Bus Protection | Ground Vehicle Electrical Systems |
|---|---|
Use Scenario: Protecting 28 V DC power distribution networks in fighter jet subsystems against load dump and lightning-induced surges. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed across main bus rails to clamp transients before they reach mission-critical flight control electronics. Use Value: Prevents latch-up and permanent damage in FPGAs and ADCs powered from the same 28 V bus by limiting clamped voltage to 243 V. | Use Scenario: Safeguarding electronic control units (ECUs) in armored personnel carriers subjected to MIL-STD-1275B-compliant 28 V bus transients. IC Role / Device Role / Timing Role: Primary overvoltage suppressor mounted directly at ECU input terminals to absorb 5000 W surge pulses.

| Tactical Radio Power Inputs | Missile Guidance System Interfaces |
Use Scenario: Securing RF power amplifier supply lines in man-portable radios exposed to electromagnetic pulse (EMP) threats. IC Role / Device Role / Timing Role: Fast-response TVS element integrated into front-end power conditioning stage to shunt EMP-induced voltage spikes. Use Value: Maintains radio operability after simulated nuclear EMP events by limiting transient voltage to below 243 V within <1 ns. | Use Scenario: Protecting inertial measurement unit (IMU) analog sensor inputs connected to 28 V vehicle bus in guided munitions. IC Role / Device Role / Timing Role: Standoff-rated TVS diode placed at IMU power entry point to prevent transient coupling into precision analog signal paths. Use Value: Preserves sensor accuracy by suppressing sub-µs transients that would otherwise saturate low-noise op-amps in signal conditioning circuitry. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6117AUS/TR | Higher screening level (Class V vs. Class S); tighter parameter tolerances and extended environmental testing | Required for space-qualified systems and DoD programs mandating Class V per MIL-PRF-19500/505 | Select JANTXV1N6117AUS/TR when radiation hardness, extended temperature validation, or zero-defect screening is mandated |
| 1N6117AUS/TR | Commercial-grade version; no MIL-PRF-19500 screening, wider parameter spreads, non-hermetic package | Suitable only for non-military industrial prototypes or cost-sensitive ground-test equipment | Choose 1N6117AUS/TR only for lab evaluation or non-flight hardware where MIL-spec compliance is not required |
Compared with JANTXV1N6117AUS/TR, the JANTX1N6117AUS/TR offers verified Class S screening at lower cost and smaller qualification scope - ideal for airborne platforms requiring proven reliability but not full space-level assurance. Against 1N6117AUS/TR, it delivers guaranteed hermeticity and military environmental robustness essential for deployed field systems.

FAQ
What is the clamping voltage specification for JANTX1N6117AUS/TR under standard surge conditions?
The JANTX1N6117AUS/TR has a maximum clamping voltage of 243 V when subjected to a 12.3 A peak pulse current with a 10/1000 µs waveform. This value is measured per MIL-STD-750 Method 2074 and ensures downstream circuitry remains within safe operating limits during load dump or lightning-induced transients on 28 V systems.
Is JANTX1N6117AUS/TR compliant with MIL-STD-1275B?
Yes, the JANTX1N6117AUS/TR is designed and tested to meet MIL-STD-1275B Section 4.5.2 surge immunity requirements. Its 5000 W peak pulse power rating, 243 V clamping voltage, and sub-1 ns response time enable direct compliance when installed per recommended layout guidelines for 28 V vehicle power systems.
What does the "JANTX" prefix indicate for JANTX1N6117AUS/TR?
The "JANTX" prefix denotes that JANTX1N6117AUS/TR is a military-qualified part meeting MIL-PRF-19500/505 Class S screening requirements. It signifies full lot acceptance testing, extended environmental stress screening, and traceable manufacturing per Defense Logistics Agency (DLA) standards - distinguishing it from commercial or JANTXV-grade variants.
Can JANTX1N6117AUS/TR be used in place of JANTXV1N6117AUS/TR?
JANTX1N6117AUS/TR is not a drop-in replacement for JANTXV1N6117AUS/TR. While both share identical electrical parameters, the JANTXV variant undergoes Class V screening - including radiation testing and enhanced burn-in - required for spaceflight and certain DoD programs. Use JANTX1N6117AUS/TR only where Class S qualification suffices.
What is the operating temperature range of JANTX1N6117AUS/TR?
The JANTX1N6117AUS/TR is rated for continuous operation from –65 °C to +175 °C ambient temperature. This wide range supports deployment in extreme environments such as aircraft engine bays, desert-ground vehicles, and high-altitude avionics enclosures without thermal derating or additional heatsinking.
