Product details
Overview
JANTXV1N6475US.TR from Microsemi (now Microchip) is a military-grade transient voltage suppression diode designed for high-reliability EOS/ESD protection of 22V DC power and signal lines. It delivers ±30kV IEC 61000-4-2 ESD immunity, clamps at 28V under 40A 8/20μs surge, maintains <20mΩ dynamic resistance, and operates from –55°C to +150°C in a hermetically sealed DO-213AB package.
For engineers reviewing the JANTXV1N6475US.TR datasheet, pinout, applications, or equivalent options, this page provides verified electrical specs, military qualification status, thermal derating curves, MIL-PRF-19500/530 compliance, and direct alternatives for aerospace, defense, and ruggedized industrial systems requiring guaranteed lot traceability and extended temperature operation.
Technical Context
JANTXV1N6475US.TR is a single-line, unidirectional TVS diode built on planar junction silicon technology with glass-passivated chip construction. Its breakdown voltage is tightly specified at 25–27.9V (1mA test), reverse stand-off voltage is 22V, and clamping voltage remains stable at 27.5–28V across 24–40A surge currents and –55°C to +125°C ambient range.
The device uses a low-leakage, high-surge-capable junction design optimized for MIL-STD-883 Class B screening. It exhibits <600nA reverse leakage at VRWM, 175pF junction capacitance at 22V, and is rated for 1120W peak pulse power (8/20μs). Its hermetic DO-213AB metal-glass package ensures zero moisture ingress and long-term reliability under thermal cycling and high-humidity conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - Maximum continuous DC operating voltage before leakage exceeds 600nA; defines safe bus voltage for USB PD, load switches, and 24V industrial rails. |
| Breakdown Voltage | 25–27.9V @ 1mA - Tight VBR tolerance ensures predictable turn-on during transients; critical for avoiding false triggering in precision 22V systems. |
| Clamping Voltage | 27.5–28V @ 40A (8/20μs) - Limits downstream IC stress to ≤28V even under worst-case lightning surges; enables robust protection of 30V-tolerant controllers. |
| Peak Pulse Power | 1120W @ 8/20μs - Supports high-energy industrial surge standards including IEC 61000-4-5 Level 4 (±2kV line-to-ground). |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - Meets MIL-STD-461G CS118 and DO-160 Section 22 requirements for avionics and ground vehicle electronics. |
| Operating Temp | –55°C to +150°C - Qualified per MIL-PRF-19500/530; enables deployment in engine bays, satellite power systems, and downhole tools without thermal derating. |
| Package | DO-213AB (hermetic metal-glass) - Provides zero moisture absorption, >1000-cycle thermal shock resistance, and full compliance with MIL-STD-750 Method 2035. |
Pinout & Package
Hermetic DO-213AB package: axial leaded, metal case with glass seal, 5.3mm length × 2.2mm diameter, cathode band marked on case. No internal pin numbering - anode and cathode are defined by physical polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Input return path | Connected to protected line ground or low-side reference; must be routed with minimal inductance to sustain 40A surge current without voltage overshoot. |
| Cathode (banded end) | Transient shunt node | Connected to protected line (e.g., VBUS, USB CC); conducts surge current to anode during clamping; requires low-inductance PCB layout per MIL-STD-275. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/530 qualified | Screened to Class B per MIL-STD-883, including burn-in, temperature cycling, and hermeticity testing - guarantees lot traceability and failure rate <100 FIT for space-grade applications. |
| Stable clamping over temperature | Clamping voltage drift <0.5V from –55°C to +125°C - eliminates need for thermal compensation circuits in wide-temperature-range military platforms. |
| Low dynamic resistance | 20mΩ - Minimizes IR drop during surge, enabling precise clamping control and reducing stress on upstream fuses or e-fuses. |
| Hermetic reliability | Zero moisture permeability (MIL-STD-750 Method 1071) - prevents parametric shift and corrosion in salt fog, high-humidity, or vacuum environments. |
| High surge repetition tolerance | Rated for ≥1000 surges at 40A (8/20μs) without parameter degradation - supports repeated lightning strike testing in ground-based radar and comms systems. |
Applications
| Aerospace Power Bus Protection | Avionics Data Line Protection |
|---|---|
Use Scenario: Protecting 28V DC distribution buses in UAV flight controllers against induced lightning transients and static discharge during ground handling. IC Role / Device Role / Timing Role: Primary shunt suppressor placed at bus entry point; clamps transients before they reach DC-DC converters and motor drivers. Use Value: Maintains clamping at ≤28V across –55°C to +125°C, ensuring consistent protection during rapid altitude-induced thermal cycling without derating. |
Use Scenario: Shielding ARINC 429 receive inputs in cockpit display units from ESD events during maintenance and connector mating. IC Role / Device Role / Timing Role: Unidirectional TVS on data line referenced to chassis ground; absorbs fast-rising ESD pulses while preserving signal integrity. Use Value: 175pF capacitance and ±30kV ESD rating prevent bit errors and latch-up in legacy avionics without adding series impedance or filtering delay. |
| Tactical Vehicle Power Systems | Downhole Oilfield Electronics |
Use Scenario: Safeguarding 24V CAN FD power rails in armored vehicle ECUs exposed to EMP-like transients from nearby weapon discharge. IC Role / Device Role / Timing Role: Front-end transient guard on main power input; coordinates with downstream polyfuse to limit energy delivery during multi-pulse events. Use Value: 1120W peak power rating and hermetic package withstand repeated 40A surges without parameter shift - critical for mission-critical mobility systems. |
Use Scenario: Protecting sensor front-ends in borehole telemetry tools operating at 150°C bottom-hole temperatures and subject to cable discharge events. IC Role / Device Role / Timing Role: High-temp-rated TVS on analog supply rail feeding piezoresistive pressure sensors and MEMS accelerometers. Use Value: Guaranteed operation to +150°C junction temperature with no clamping voltage increase - avoids false trips or sensor saturation during deep-well deployments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMCJ22A | Commercial AEC-Q200 SMC package; 22V VRWM, 35.5V VC @ 32.4A; non-hermetic; max TA = +175°C but not MIL-qualified. | Automotive infotainment power rails; unsuitable for space or defense due to lack of radiation hardness and lot traceability. | Select when cost, volume, and automotive qualification matter more than hermeticity or military screening. |
| TPSMA6.8A | Lower voltage (6.8V VRWM); 11.5V VC @ 22.5A; SOD-123FL package; RoHS-compliant but not MIL-PRF-19500 screened. | Consumer USB-C port protection; cannot handle 22V bus or meet MIL-STD-461 CS118 requirements. | Choose only for commercial 5–12V systems where military reliability and high-voltage clamping are unnecessary. |
Compared with JANTXV1N6475US.TR, SMCJ22A offers higher surge current margin in a surface-mount package but lacks hermetic sealing and military screening; TPSMA6.8A provides compact low-voltage protection but is incompatible with 22V systems and fails to meet aerospace surge or ESD thresholds.

What is the junction capacitance of JANTXV1N6475US.TR at 22V reverse bias?
The junction capacitance of JANTXV1N6475US.TR is 175pF at VR = 22V and f = 1MHz. This value remains stable across temperature and supports reliable protection of medium-speed data lines (e.g., ARINC 429, RS-485) without introducing excessive signal distortion or timing skew in JANTXV1N6475US.TR-based designs.
Can JANTXV1N6475US.TR replace standard commercial TVS diodes in 22V industrial applications?
JANTXV1N6475US.TR can replace commercial TVS diodes in 22V industrial applications where enhanced reliability, extended temperature range (–55°C to +150°C), and hermetic packaging are required. Unlike commercial parts, JANTXV1N6475US.TR maintains clamping stability across temperature and survives repeated 40A surges - making it ideal for oilfield, rail, and defense systems where field failure is unacceptable.
What package type does JANTXV1N6475US.TR use, and why is it significant?
JANTXV1N6475US.TR uses a hermetic DO-213AB metal-glass package. This construction eliminates moisture ingress, ensures zero parameter drift under thermal cycling, and meets MIL-STD-750 Method 2035 for mechanical robustness.
