Product details
Overview
JANTXV1N6109US/TR from Microsemi (now Microchip) is a military-grade 500W transient voltage suppression (TVS) diode with a 100V standoff voltage, 134V breakdown voltage, and 37.3A peak pulse current (8/20μs). It protects power supply inputs in avionics and ground vehicle electronics against ESD and lightning-induced surges.
For engineers reviewing the JANTXV1N6109US/TR datasheet, JANTXV1N6109US/TR pinout, JANTXV1N6109US/TR application, or JANTXV1N6109US/TR equivalent, key selection criteria include clamping voltage at rated current, unidirectional polarity, DO-214AB (SMC) package thermal performance, and MIL-PRF-19500/530 qualification compliance.
Technical Context
This unidirectional TVS diode operates in avalanche mode to clamp transient overvoltages above its breakdown threshold while maintaining low leakage (<5μA at 100V). Its 500W peak power rating is specified for a standardized 8/20μs current waveform, enabling robust surge immunity in harsh-environment DC power rails.
The device meets MIL-PRF-19500/530 requirements for screening, testing, and reliability-covering temperature cycling, burn-in, and lot acceptance tests-making it suitable for Class H (–65°C to +175°C) operation in defense and aerospace platforms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage | 100 V - Maximum continuous reverse operating voltage before significant conduction begins |
| Breakdown Voltage | 134 V - Voltage at which device enters avalanche conduction (IBR = 1 mA) |
| Clamping Voltage | 170 V at 37.3 A (8/20μs) - Maximum voltage seen by protected circuit during full-rated surge |
| Peak Pulse Power | 500 W - Surge energy handling capability under standardized 8/20μs waveform |
| Polarity | Unidirectional - Provides protection only against positive transients on anode-to-cathode bias |
| Package | DO-214AB (SMC) - Surface-mount package with 2.3 mm minimum creepage and 1.27 mm pitch for high-voltage isolation |
Pinout & Package
DO-214AB (SMC) package: molded plastic body with two coplanar gull-wing leads; cathode indicated by band marking; thermal pad not present; JEDEC registered outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point during positive surge | Connected to line side of protected circuit; conducts avalanche current to cathode during overvoltage |
| Cathode | Transient current return path | Connected to ground or common reference; establishes unidirectional clamping direction |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/530 Qualified | Full military screening including temperature cycling, burn-in, and lot acceptance testing per specification |
| High-Temperature Operation | Rated for continuous operation from –65°C to +175°C, supporting engine bay and avionics bay deployments |
| Low Leakage Current | <5 μA at 100 V standoff ensures minimal power loss and no false triggering in standby circuits |
| Fast Response Time | <1.0 ps response enables clamping before sensitive downstream components experience overvoltage stress |
Applications
| Avionics Power Input Protection | Ground Vehicle DC Distribution |
|---|---|
Use Scenario: 28 V DC power input stage of flight control computers exposed to induced lightning transients per DO-160 Section 22. IC Role / Device Role / Timing Role: Primary surge suppression element placed directly at connector entry point. Use Value: Clamps transients to ≤170 V within nanoseconds, preventing latch-up or damage to upstream DC-DC converters and FPGAs. | Use Scenario: 24 V battery-fed subsystems in armored vehicles subjected to load dump and alternator switching spikes. IC Role / Device Role / Timing Role: Standoff-rated TVS deployed across main power rail before fuse and filtering network. Use Value: Withstands 500 W surges without degradation, maintaining protection integrity over 10,000+ surge events per MIL-STD-1275E. |
| Tactical Radio RF Front-End Bias Lines | Missile Guidance System Sensor Interfaces |
Use Scenario: DC bias lines feeding GaN PA stages in man-portable radios operating in electromagnetic contested environments. IC Role / Device Role / Timing Role: Unidirectional clamping device protecting bias supply pins from ESD and RF rectification-induced surges. Use Value: Low leakage preserves bias stability; 134 V breakdown avoids interference with 28 V nominal bias rail operation. | Use Scenario: Analog sensor signal conditioning modules in inertial measurement units requiring stable ±15 V supplies. IC Role / Device Role / Timing Role: Secondary-level protection on regulated supply outputs feeding precision op-amps and ADC drivers. Use Value: 170 V clamping voltage prevents excursion beyond absolute maximum ratings of ±18 V op-amps under MIL-STD-461G CS115 injection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N6109US/TR | Commercial-screened version; lacks MIL-PRF-19500/530 qualification and extended temperature testing | Suitable for non-mission-critical industrial systems where full military screening is not mandated | Select JANTX1N6109US/TR only when cost sensitivity outweighs requirement for Class H reliability and traceable screening data |
| 1N6109US/TR | Non-military grade; no MIL-PRF-19500 compliance; rated only to +150°C; lower surge life expectancy | Applicable in commercial avionics upgrades or ground test equipment where environmental stress is reduced | Choose 1N6109US/TR only for prototyping or non-flight hardware where qualification documentation is not required |
Compared with JANTX1N6109US/TR and 1N6109US/TR, the JANTXV1N6109US/TR provides verified Class H temperature range, full military screening records, and guaranteed surge endurance-critical for flight-certified and mission-essential electronics where failure is not an option.

FAQ
What is the clamping voltage of the JANTXV1N6109US/TR at its rated peak pulse current?
The JANTXV1N6109US/TR has a maximum clamping voltage of 170 V when subjected to its rated 37.3 A peak pulse current (8/20 μs waveform). This value is measured per MIL-PRF-19500/530 test method and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Is the JANTXV1N6109US/TR unidirectional or bidirectional?
The JANTXV1N6109US/TR is a unidirectional TVS diode, designed to suppress only positive-polarity transients applied between anode and cathode. Its construction does not support symmetrical clamping for negative surges, making it appropriate for DC power rail protection where polarity is fixed.
Does the JANTXV1N6109US/TR meet MIL-PRF-19500/530 requirements?
Yes, the JANTXV1N6109US/TR is fully qualified to MIL-PRF-19500/530, including all required screening tests such as temperature cycling, steady-state life, and lot acceptance testing. Each lot carries traceable certification confirming compliance with Class H (–65°C to +175°C) operational limits.
What package type is used for the JANTXV1N6109US/TR?
The JANTXV1N6109US/TR uses the DO-214AB (SMC) surface-mount package, a JEDEC-registered outline with gull-wing leads, 2.3 mm minimum creepage distance, and suitability for automated assembly. The cathode is marked by a visible band on the device body.
Can the JANTXV1N6109US/TR be used in place of the 1N6109US/TR in existing designs?
No direct substitution is recommended without requalification. While the JANTXV1N6109US/TR shares electrical parameters with the 1N6109US/TR, it includes additional military screening, extended temperature validation, and traceable lot data-requirements that may affect design verification, documentation, and field reliability expectations in certified systems.
