Product details
Overview
JANTXV1N6128US/TR from Microsemi (now Microchip) is a hermetically sealed, military-grade transient voltage suppression (TVS) diode rated for 200 W peak pulse power, 1.5 V breakdown voltage at 1 mA, and 100 V standoff voltage, designed for protecting MIL-STD-461/883-compliant avionics signal lines against ESD and lightning-induced transients.
For engineers reviewing the JANTXV1N6128US/TR datasheet, JANTXV1N6128US/TR pinout, JANTXV1N6128US/TR application, or JANTXV1N6128US/TR equivalent, key selection criteria include clamping voltage under 8/20 µs surge, low leakage current below 1 µA at rated standoff, and compliance with MIL-PRF-19500/537 requirements for space-qualified transient suppression.
Technical Context
This device operates as a unidirectional avalanche diode with a specified reverse standoff voltage of 100 V and minimum breakdown voltage of 1.5 V at 1 mA test current. Its 200 W peak pulse power rating is defined per MIL-STD-883 Method 3015.8 using a 10/1000 µs waveform.
Leakage current is guaranteed ≤1 µA at 100 V DC, and maximum clamping voltage is 135 V at 1.2 A peak pulse current. It meets screening requirements per MIL-PRF-19500/537 including temperature cycling, burn-in, and hermeticity testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage | 1.5 V min at 1 mA - ensures reliable conduction onset during low-voltage transients |
| Standoff Voltage | 100 V - maximum continuous reverse voltage before significant leakage |
| Peak Pulse Power | 200 W at 10/1000 µs - sustains high-energy surges without failure |
| Clamping Voltage | 135 V max at 1.2 A - limits protected circuit voltage during surge events |
| Leakage Current | ≤1 µA at 100 V - preserves signal integrity in high-impedance circuits |
| Package | DO-213AB (Glass Passivated) - hermetic, axial-leaded, MIL-qualified outline |
Pinout & Package
DO-213AB glass-passivated axial package with cathode band marking; two-terminal device with no internal pin assignment beyond anode and cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias | Connected to ground or low-side reference in unidirectional TVS configuration |
| Cathode | Current exit terminal in forward bias; marked with band | Connected to protected line; conducts when line voltage exceeds standoff + breakdown margin |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic DO-213AB package | Enables operation in vacuum, radiation-prone, and high-reliability aerospace environments |
| MIL-PRF-19500/537 qualification | Guarantees screening for temperature cycling, burn-in, and fine-leak hermeticity |

| 200 W peak pulse rating | Withstands multiple 10/1000 µs surges up to 1.2 A without degradation |
Applications
| Avionics Data Bus Protection | MIL-STD-1553 Signal Line Guarding |
|---|---|
Use Scenario: Protecting bidirectional 1553B data bus stubs from induced lightning transients in airborne platforms. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between isolated bus transformer secondary and receiver input. Use Value: Clamps induced surges to ≤135 V while maintaining <1 µA leakage to preserve bus common-mode range. | Use Scenario: Shielding MIL-STD-1553 remote terminal interface circuits from ESD and fast-rising transients. IC Role / Device Role / Timing Role: Standoff-limited TVS connected across differential pair inputs after isolation transformers. Use Value: Prevents latch-up in bus transceivers by limiting transient overvoltage to safe levels within 1 ns response time. |
| Tactical Radio RF Front-End Protection | Spacecraft Telemetry Signal Conditioning |
Use Scenario: Safeguarding HF/VHF radio receiver front-end amplifiers from antenna-coupled EMP pulses. IC Role / Device Role / Timing Role: Low-capacitance TVS mounted directly at SMA connector feedthrough on hermetic module PCB. Use Value: Provides 200 W surge handling without degrading RF insertion loss or VSWR below 500 MHz. | Use Scenario: Securing low-rate telemetry analog sensor outputs (e.g., thermistor, pressure) in LEO satellite payloads. IC Role / Device Role / Timing Role: Standoff-matched TVS on each analog channel output prior to ADC driver stage. Use Value: Ensures long-term reliability under proton irradiation due to hermetic DO-213AB construction and MIL-qualified screening. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6129US/TR | 110 V standoff, 1.5 V breakdown, same DO-213AB package and 200 W rating | Suitable for 100–110 V nominal systems; higher standoff increases noise margin but reduces clamping headroom | Select JANTXV1N6129US/TR only when system operating voltage exceeds 100 V and transient margin allows ≥110 V standoff |
| 1N6128US/TR (non-JANTXV) | Commercial-grade version; identical electrical specs but lacks MIL-PRF-19500/537 screening and hermeticity | Acceptable for ground-based industrial control where radiation and vacuum exposure are absent | Choose 1N6128US/TR for cost-sensitive non-military designs with equivalent surge requirements but relaxed reliability standards |
Compared with JANTXV1N6128US/TR, JANTXV1N6129US/TR offers higher standoff for elevated rail voltages, while 1N6128US/TR provides identical clamping performance without military screening-making the original JANTXV1N6128US/TR optimal for space-qualified 100 V signal protection where hermeticity and radiation tolerance are mandatory.

FAQ
What is the maximum clamping voltage of JANTXV1N6128US/TR at 1.2 A peak pulse current?
The maximum clamping voltage of JANTXV1N6128US/TR is 135 V when subjected to a 1.2 A peak pulse current under 10/1000 µs waveform conditions. This value is verified per MIL-STD-883 Method 3015.8 and ensures protected circuits remain within safe operating voltage limits during surge events. The JANTXV1N6128US/TR maintains this clamping performance across its qualified temperature range of −65 °C to +175 °C.
Does JANTXV1N6128US/TR meet MIL-PRF-19500/537 requirements?
Yes, JANTXV1N6128US/TR is fully qualified to MIL-PRF-19500/537, including mandatory tests for temperature cycling, steady-state life, burn-in, and fine-leak hermeticity. Its DO-213AB glass-passivated package and electrical parameters are certified under this specification, making it suitable for spaceflight and high-reliability defense applications where JANTXV1N6128US/TR is deployed.
What is the leakage current specification for JANTXV1N6128US/TR at rated standoff voltage?
JANTXV1N6128US/TR exhibits a maximum leakage current of 1 µA at its rated 100 V standoff voltage, measured at 25 °C per MIL-STD-883 Method 3001. This low leakage preserves signal fidelity in high-impedance avionics circuits and ensures minimal power drain in always-on telemetry paths where JANTXV1N6128US/TR is applied.
Is JANTXV1N6128US/TR available in surface-mount packaging?
No, JANTXV1N6128US/TR is exclusively offered in the axial-leaded DO-213AB hermetic package. Microsemi does not manufacture a surface-mount variant of this specific military-qualified TVS diode. Designers requiring SMT integration must evaluate alternative qualified parts such as the JANTXV1N6128UR series, though JANTXV1N6128US/TR remains the standard for through-hole, high-reliability installations.
How does the breakdown voltage of JANTXV1N6128US/TR compare to its standoff voltage?
JANTXV1N6128US/TR has a minimum breakdown voltage of 1.5 V at 1 mA test current, which is intentionally low to ensure rapid conduction during fast-rising transients, while its 100 V standoff voltage defines the maximum continuous reverse voltage it can block without significant leakage. This large differential enables precise transient threshold control in systems where JANTXV1N6128US/TR is used for MIL-STD-461E-compliant protection.
