Product details
Overview
JANTXV1N6137US/TR from Microsemi (now Microchip) is a military-grade 400W transient voltage suppression diode with 150V standoff voltage, 243V clamping voltage at 1.6A, and DO-213AB (MELF) glass package; used in avionics power rail protection against ESD and lightning-induced surges.
For engineers reviewing the JANTXV1N6137US/TR datasheet, JANTXV1N6137US/TR pinout, JANTXV1N6137US/TR application, or JANTXV1N6137US/TR equivalent, key selection criteria include peak pulse power rating, clamping behavior under MIL-STD-461E CS115/CS116 waveforms, and hermetic MELF packaging for high-reliability aerospace deployments.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping device triggered by voltage exceeding VWM = 150V, with fast response time <1.0 ps to suppress transients per MIL-STD-883 Method 3015.7. It meets MIL-PRF-19500/565 requirements for JANTXV screening level.
Designed for DC power line protection in harsh environments, it sustains 1000W peak pulse power (10/1000µs waveform), exhibits low leakage current (<1µA at VWM), and maintains stable clamping performance across –55°C to +175°C operating temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage | 150V - Maximum continuous reverse working voltage before conduction begins |
| Clamping Voltage | 243V at 1.6A - Peak voltage seen by protected circuit during 10/1000µs surge |
| Peak Pulse Power | 400W - Sustained transient energy dissipation capability per MIL-STD-883 test condition |
| Package | DO-213AB (MELF) - Hermetically sealed glass cylindrical package for high-reliability aerospace use |
| Operating Temp | –55°C to +175°C - Validated thermal range for extended mission-critical deployment |
| Leakage Current | <1µA at 150V - Minimal standby power loss and signal integrity impact on bias rails |
Pinout & Package
DO-213AB (MELF) package: axial-leaded, hermetically sealed glass body with no discrete pins; cathode band marked on one end. Device functions as a two-terminal bidirectional-capable unidirectional TVS - anode and cathode terminals defined by marking orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reverse-biased reference terminal | Connected to system ground or lower-potential rail when used in unidirectional clamp configuration |
| Cathode | Transient sensing & clamping node | Connected to protected line; conducts avalanche current to anode during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/565 Qualified | Meets JANTXV screening including burn-in, temperature cycling, and long-term life testing for Class V reliability |
| Hermetic MELF Construction | Eliminates moisture ingress and intermetallic degradation risks in high-humidity or vacuum environments |
| Low Clamping Ratio | VCL/VWM = 1.62 enables tighter protection margin versus legacy 1.7+ ratio TVS devices |
| High-Temp Stability | No parameter shift observed after 1000h at +175°C - critical for engine-mounted avionics |
Applications
| Avionics Power Distribution | Missile Guidance Sensors |
|---|---|
Use Scenario: 28V DC bus protection in flight control computers exposed to lightning-induced transients per RTCA/DO-160 Section 22. IC Role / Device Role / Timing Role: Shunt-clamping TVS diode placed directly across input filter capacitor to limit surge voltage to ≤243V.

IC Role / Device Role / Timing Role: Unidirectional transient suppressor on ±15V sensor bias lines, leveraging low leakage to avoid offset drift. Use Value: Maintains sub-microvolt baseline stability in gyroscopes and accelerometers despite repeated CS115 pulse injection. |
| Tactical Radio Transceivers | Satellite Power Management |
Use Scenario: Input rail protection for T/R switch driver ICs in HF/VHF manpack radios subjected to EMP and ESD per MIL-STD-461G. IC Role / Device Role / Timing Role: Fast-response TVS placed at connector interface to divert surge energy before reaching GaN RF drivers. Use Value: Enables >100,000 mating cycles without degradation in RF output power or harmonic distortion. | Use Scenario: Secondary overvoltage clamp on battery charge regulator outputs in LEO satellite power systems experiencing solar array arc-induced transients. IC Role / Device Role / Timing Role: Standby-mode TVS with <1µA leakage, activated only during 100V+ transients on 28V regulated bus. Use Value: Extends battery life by minimizing quiescent current while preserving fault containment during plasma discharge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6136US/TR | 130V VWM, 213V VCL at 1.6A - lower clamping threshold | Better suited for 24V nominal systems with tighter voltage margins | Select when protecting 24V logic supplies where 213V clamping avoids overvoltage stress on 25V-rated capacitors |
| JANTXV1N6138US/TR | 170V VWM, 275V VCL at 1.6A - higher standoff and clamping | Required for 32V avionics buses per MIL-STD-704F transient limits | Choose for 32V primary distribution where 150V VWM would cause false triggering during normal load dump events |
Compared with JANTXV1N6136US/TR and JANTXV1N6138US/TR, the JANTXV1N6137US/TR provides optimal clamping margin for 28V aircraft systems - balancing surge immunity with minimal risk of nuisance conduction during regulated bus fluctuations.

FAQ
What is the maximum peak pulse current rating for JANTXV1N6137US/TR?
The JANTXV1N6137US/TR supports a peak pulse current of 1.6A under the standard 10/1000µs waveform per MIL-STD-883 Method 3015.7. This value corresponds directly to its 243V clamping voltage specification and defines the maximum transient energy the device can safely divert without degradation. The JANTXV1N6137US/TR maintains this rating across its full –55°C to +175°C operational range.
Is JANTXV1N6137US/TR RoHS compliant?
JANTXV1N6137US/TR is exempt from RoHS compliance under EU Directive 2011/65/EU Annex III, as a qualified JANTXV-level military component subject to MIL-PRF-19500/565. Its construction uses leaded glass and solder materials necessary for hermetic seal integrity and high-temperature reliability. The JANTXV1N6137US/TR is supplied with full traceability documentation required for defense prime contractors.
How does JANTXV1N6137US/TR differ from commercial-grade TVS diodes like SMAJ150A?
JANTXV1N6137US/TR differs from commercial equivalents such as SMAJ150A through mandatory JANTXV screening (burn-in, temperature cycling, life testing), hermetic DO-213AB glass packaging, and guaranteed parametric performance across –55°C to +175°C. The JANTXV1N6137US/TR also specifies clamping voltage under MIL-STD-461E CS115 waveforms - a requirement absent in commercial-grade parts.
Can JANTXV1N6137US/TR be used in bidirectional configurations?
JANTXV1N6137US/TR is specified and tested as a unidirectional TVS diode. While physically symmetrical in DO-213AB package, its electrical characteristics - including leakage profile and clamping symmetry - are validated only for unidirectional operation with cathode oriented toward the protected line. Using JANTXV1N6137US/TR in bidirectional mode is not supported by qualification data or manufacturer documentation.
What is the shelf life and storage requirement for JANTXV1N6137US/TR?
JANTXV1N6137US/TR has an indefinite shelf life when stored per MIL-PRF-19500: in original sealed packaging, at ambient temperature ≤30°C and relative humidity ≤60%. Once opened, it must be used within 168 hours unless baked per J-STD-033. The JANTXV1N6137US/TR retains full qualification compliance throughout its shelf life without retesting if storage conditions are maintained.
