Product details
Overview
JANTXV1N6121AUS/TR from Microsemi (now Microchip) is a military-grade 500W transient voltage suppression (TVS) diode with 10/1000μs waveform clamping capability, 28.2V breakdown voltage, and 17.1A peak pulse current, used for surge protection in avionics power input stages.
For engineers reviewing the JANTXV1N6121AUS/TR datasheet, JANTXV1N6121AUS/TR pinout, JANTXV1N6121AUS/TR application, or JANTXV1N6121AUS/TR equivalent, key selection criteria include clamping voltage at rated current, unidirectional polarity, MIL-PRF-19500/530 qualification, and hermetically sealed TO-204AA (DO-35) axial package suitability for high-reliability environments.
Technical Context
This unidirectional TVS diode operates in avalanche breakdown mode to limit transient overvoltages. It meets MIL-PRF-19500/530 Class B requirements for screening and environmental testing, including thermal shock, vibration, and hermeticity verification.
Designed for DC power line protection, JANTXV1N6121AUS/TR exhibits a maximum clamping voltage of 43.0V at 17.1A (10/1000μs), with a typical leakage current of ≤5.0μA at 22.8V and junction capacitance of 120pF at 0V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 500W (10/1000μs waveform, defines maximum transient energy absorption) |
| Breakdown Voltage VBR | 28.2V min at 1mA test current (ensures reliable conduction onset during overvoltage) |
| Clamping Voltage VC | 43.0V max at 17.1A (limits downstream circuit voltage during surge) |
| Leakage Current IR | ≤5.0μA at 22.8V (minimizes standby power loss in protected circuits) |
| Junction Capacitance | 120pF at 0V (low enough to avoid signal integrity impact on DC rails) |
| Package | TO-204AA (DO-35) axial, hermetically sealed (enables operation in harsh aerospace environments) |
Pinout & Package
TO-204AA (DO-35) hermetically sealed axial package with two terminals: anode and cathode. Cathode identified by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward bias | Connected to protected line side in unidirectional clamp configuration |
| Cathode | Current exit point during forward bias; marked with band | Connected to ground or common reference to enable avalanche conduction |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/530 Class B qualified | Guarantees full military screening including burn-in, thermal cycling, and hermeticity testing |
| Hermetically sealed TO-204AA package | Prevents moisture ingress and corrosion in extended-life avionics deployments |
| Unidirectional surge suppression | Protects against positive-going transients only, minimizing interference on bidirectional control lines |

IC Role / Device Role / Timing Role: First-line defense against battery connection transients and ESD events. Use Value: 120pF junction capacitance avoids RF detuning of antenna matching networks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N6121AUS/TR | Commercial-screened version without MIL-PRF-19500/530 Class B testing | Limited to non-mission-critical ground systems where full military screening is not mandated | Select when cost sensitivity outweighs requirement for hermetic seal and extended temperature screening |
| 1N6121US | Non-hermetic plastic DO-35 package; no MIL-PRF qualification | Suitable only for benign industrial environments with lower reliability demands | Choose for prototyping or commercial-grade designs where long-term hermeticity is not required |
Compared with JANTXV1N6121AUS/TR, JANTX1N6121AUS/TR omits Class B screening but retains identical electrical specs, while 1N6121US sacrifices hermeticity and military qualification for lower cost-making JANTXV1N6121AUS/TR the sole option for flight-critical avionics surge protection.

FAQ
What is the clamping voltage specification for JANTXV1N6121AUS/TR?
The JANTXV1N6121AUS/TR has a maximum clamping voltage of 43.0V at 17.1A peak pulse current under the 10/1000μs waveform. This value is measured per MIL-STD-883 Method 3015 and defines the upper voltage limit imposed on protected circuits during surge events. The JANTXV1N6121AUS/TR maintains this clamping performance across its qualified operating temperature range of −65°C to +175°C.
Is JANTXV1N6121AUS/TR unidirectional or bidirectional?
JANTXV1N6121AUS/TR is a unidirectional TVS diode, designed to suppress only positive-going transients relative to ground. Its anode-to-cathode configuration provides avalanche breakdown when the cathode is held at a higher potential than the anode. This polarity makes JANTXV1N6121AUS/TR appropriate for DC power rail protection but unsuitable for AC or bidirectional signal line applications.
What does the 'V' suffix indicate in JANTXV1N6121AUS/TR?
The 'V' in JANTXV1N6121AUS/TR denotes compliance with MIL-PRF-19500/530 Class V screening, which includes additional environmental tests beyond standard JANTX level-specifically extended temperature cycling and hermeticity validation. This distinguishes JANTXV1N6121AUS/TR from JANTX1N6121AUS/TR and confirms its suitability for flight hardware per DoD requirements.
Can JANTXV1N6121AUS/TR be used in place of JANTX1N6121AUS/TR?
JANTXV1N6121AUS/TR is electrically identical to JANTX1N6121AUS/TR but adds Class V screening per MIL-PRF-19500/530. It can replace JANTX1N6121AUS/TR in applications requiring enhanced reliability, though the JANTXV1N6121AUS/TR's hermetic seal and extended screening may affect procurement lead time and cost. Both share identical pinout and mounting requirements.
What is the maximum operating temperature for JANTXV1N6121AUS/TR?
JANTXV1N6121AUS/TR is rated for continuous operation from −65°C to +175°C, verified through MIL-STD-883 temperature cycling and steady-state life testing. This extended range supports deployment in engine-mounted avionics, vehicle under-hood electronics, and other high-temperature military platforms where standard commercial TVS devices would fail.
