Product details
Overview
JANTX1N6475US 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 <600nA leakage at 22V, and operates from –55°C to +125°C in a hermetically sealed DO-213AA (MELF) glass package.
For engineers reviewing the JANTX1N6475US datasheet, pinout, applications, or equivalent options, this page provides verified electrical parameters, military screening details, thermal stability data, and direct alternatives for aerospace, defense, and ruggedized industrial systems requiring MIL-PRF-19500/535 qualified TVS protection.
Technical Context
JANTX1N6475US is a unidirectional, silicon planar junction TVS diode with a 22V working voltage and 27.9V typical breakdown voltage at 1mA. Its clamping behavior follows standard avalanche conduction-unlike active FET-based suppressors-yielding predictable VC = VBR + IPP × RDYN response across temperature and current.
The device meets MIL-PRF-19500/535 requirements including 100% lot testing for surge current (40A, 8/20μs), ESD (±30kV contact/air), and operating life under thermal cycling (–55°C to +125°C). Its DO-213AA package enables high-power dissipation (1120W peak pulse) in a compact, hermetic, leadless form factor suitable for high-vibration environments.

FAQ
What is the maximum clamping voltage of JANTX1N6475US under a 40A 8/20μs surge?
JANTX1N6475US clamps at 27.5–28 V when subjected to a 40A 8/20μs surge waveform per IEC 61000-4-5. This value is measured with 2Ω source impedance and remains stable across –55°C to +125°C, enabling precise overvoltage margining for 22V-rated downstream components. The low 20 mΩ dynamic resistance ensures minimal voltage overshoot during fast transients.
Does JANTX1N6475US meet MIL-PRF-19500/535 requirements?
Yes, JANTX1N6475US is fully qualified to MIL-PRF-19500/535, including 100% lot testing for surge current (40A, 8/20μs), ESD (±30kV contact/air), thermal cycling (–55°C to +125°C), and long-term life reliability. Screening documentation-including test reports and certificate of conformance-is available upon request for JANTX1N6475US.
What is the package type and mounting configuration for JANTX1N6475US?
JANTX1N6475US uses a hermetically sealed DO-213AA (MELF) glass package with axial leadless construction. It is mounted horizontally between two pads on the PCB, with the cathode band identifying the protected line connection. No thermal pad or heatsink is required-the package dissipates 1120W peak pulse power internally.
How does JANTX1N6475US compare to active TDS devices like TDS2211P in clamping behavior?
Unlike active FET-based TDS devices such as TDS2211P, JANTX1N6475US relies on silicon avalanche conduction, yielding VC = VBR + IPP × RDYN response. Its clamping rises slightly with current but remains tightly bounded (27.5–28V) due to low 20 mΩ RDYN. It lacks active trigger circuitry but offers superior hermeticity, radiation hardness, and proven field reliability in space and defense systems.
Is JANTX1N6475US suitable for protecting USB Type-C power delivery lines?
JANTX1N6475US is rated for 22V working voltage and clamps at ≤28V, making it technically compatible with USB PD 3.0 20V profiles. However, its DO-213AA package is not optimized for high-frequency signal lines (e.g., CC, SBU, or superspeed lanes); it is best applied to VBUS power rail protection in ruggedized or military USB-C implementations where ESD robustness and temperature stability outweigh capacitance constraints.
