Product details
Overview
JANTXV1N6121US/TR from Microsemi (now Microchip) is a military-grade 500W transient voltage suppression (TVS) diode rated for 180V standoff voltage, 200V breakdown voltage, and 270V clamping voltage at 20A peak pulse current, used in avionics power rail protection.
For engineers reviewing the JANTXV1N6121US/TR datasheet, JANTXV1N6121US/TR pinout, JANTXV1N6121US/TR application, or JANTXV1N6121US/TR equivalent, key selection factors include MIL-PRF-19500/534 compliance, unidirectional polarity, DO-213AB package, and 1μs response time under surge conditions.
Technical Context
This unidirectional TVS diode operates with a maximum leakage current of 5μA at 180V and exhibits a typical junction capacitance of 120pF at 0V, enabling effective ESD and lightning-induced surge suppression in high-reliability analog and power interfaces.
Designed for operation across –65°C to +175°C ambient range, it supports sustained DC bias up to 180V and delivers repeatable clamping performance under 10/1000μs waveform surges per MIL-STD-883 Method 3015.8.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage | 180V - Maximum continuous reverse operating voltage before conduction begins |
| Breakdown Voltage | 200V - Voltage at which device enters avalanche conduction (IBR = 1mA) |
| Clamping Voltage | 270V at 20A - Peak voltage seen by protected circuit during 10/1000μs surge |
| Peak Pulse Power | 500W - Maximum non-repetitive surge energy dissipation capability |
| Junction Capacitance | 120pF at 0V - Minimal signal distortion in high-speed analog sensing paths |
| Leakage Current | ≤5μA at 180V - Low standby power loss in always-on avionics subsystems |
Pinout & Package
Package: DO-213AB (Glass Passivated Axial Lead), hermetically sealed, axial-leaded metal-glass construction compliant with MIL-PRF-19500/534.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Cathode | Current exit point during forward conduction; cathode-bar marked end | Connected to protected line (e.g., 28V aircraft bus) to enable reverse-biased clamping |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/534 Qualified | Meets screening, testing, and traceability requirements for Class H military applications |
| Unidirectional Clamping | Protects against negative transients only; preserves positive signal integrity in DC-biased rails |
| 1μs Response Time | Activates within 1 microsecond of overvoltage onset, limiting energy delivery to downstream ICs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N6121US | No TR suffix - bulk packaged, not tape-and-reel; identical electrical specs and screening | Same MIL-PRF-19500/534 Class H qualification; suitable for manual assembly or low-volume prototyping | Select JANTX1N6121US when automated SMT placement is not required and traceability per lot is acceptable |
| 1N6121US/TR | Commercial-grade version - no MIL-PRF-19500 screening; same DO-213AB package and clamping parameters | Limited to non-mission-critical industrial systems where extended temperature range and radiation tolerance are not required | Choose 1N6121US/TR only for cost-sensitive ground-based test equipment with ambient < +125°C |
Compared with JANTXV1N6121US/TR, JANTX1N6121US offers identical protection performance but lacks tape-and-reel packaging for pick-and-place, while 1N6121US/TR omits military screening yet retains core clamping behavior for less demanding environments.

FAQ
What is the clamping voltage specification for JANTXV1N6121US/TR?
The JANTXV1N6121US/TR has a maximum clamping voltage of 270V at 20A peak pulse current under 10/1000μs waveform conditions. This value is verified per MIL-STD-883 Method 3015.8 and defines the upper voltage limit imposed on protected circuitry during surge events. The JANTXV1N6121US/TR maintains this clamping performance across its full qualified temperature range.
Is JANTXV1N6121US/TR suitable for bidirectional transient suppression?
No, JANTXV1N6121US/TR is a unidirectional TVS diode and provides clamping only for negative-going transients relative to its cathode connection. It must be installed with cathode toward the protected line and anode to ground. For bidirectional protection, two JANTXV1N6121US/TR devices in series-opposing configuration or a dedicated bidirectional part like JANTXV1N6122US/TR would be required.
What does the 'V' in JANTXV1N6121US/TR indicate?
The 'V' in JANTXV1N6121US/TR denotes compliance with the JAN (Joint Army-Navy) specification level under MIL-PRF-19500/534, specifically qualifying the device for Class V screening - the highest reliability tier for discrete semiconductors, including extended burn-in, thermal shock, and hermeticity testing. This distinguishes it from JANTX (Class X) and JANTXV (Class V) variants.
Does JANTXV1N6121US/TR require derating at elevated temperatures?
Yes, JANTXV1N6121US/TR requires power derating above +125°C ambient. Its peak pulse power rating decreases linearly from 500W at 25°C to approximately 250W at +175°C, per the manufacturer's derating curve. Designers must apply this derating when sizing JANTXV1N6121US/TR for high-temperature avionics bays or enclosed weapon system enclosures.
Can JANTXV1N6121US/TR be used in place of JANTX1N6121US in automated assembly?
Yes, JANTXV1N6121US/TR is supplied in tape-and-reel format (TR suffix) and is fully compatible with standard axial-lead pick-and-place equipment calibrated for DO-213AB components. Unlike JANTX1N6121US (bulk packaged), the JANTXV1N6121US/TR enables high-yield automated insertion while maintaining identical electrical and screening specifications.
