Product details
Overview
JANTXV1N6475US 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 features ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping at 40A, 20mΩ dynamic resistance, and 175pF junction capacitance - enabling robust protection in USB PD, industrial IoT, and load switch input circuits.
For engineers reviewing the JANTXV1N6475US datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, clamping stability across temperature, functional comparison with conventional TVS diodes, and OEM supply support for aerospace, defense, and ruggedized embedded systems.
Technical Context
JANTXV1N6475US implements a transient diverting architecture using a surge-rated FET as the primary shunt element, activated by a precision trigger circuit - unlike standard PN-junction TVS diodes. Its clamping voltage remains nearly constant (27.5–28V) from 24A to 40A and across −40°C to +125°C due to decreasing RDS(on) under surge conditions.
The device operates with a 22V reverse stand-off voltage (VRWM) and 25–27.9V breakdown (VBR), supports unsymmetrical line protection per IEC 61000-4-5 (±1kV, 1.2/50μs), and delivers 1120W peak pulse power. Its 175pF capacitance at 22V/1MHz and 130–600nA leakage ensure compatibility with high-speed interfaces when used on power rails.
Key Specifications

|---|---|
|
Use Scenario: Protecting VBUS lines in USB-C ports supporting up to 20V/5A PD negotiation against lightning-induced surges and hot-plug ESD. IC Role / Device Role / Timing Role: Primary EOS suppressor placed between connector and load switch or PD controller - activates within nanoseconds upon overvoltage detection. Use Value: Maintains 27.5V clamping at 40A and 125°C, preventing damage to 24V-tolerant PD controllers where conventional TVS would clamp >38V at same conditions. |
Use Scenario: Shielding enable and input pins of high-side load switches (e.g., HS2950P) in programmable logic controllers and remote metering terminals. IC Role / Device Role / Timing Role: Front-end transient guard - diverts surge energy away from sensitive gate-drive circuitry and internal FETs during field wiring faults. Use Value: Limits voltage stress to <28V during ±1kV IEC 61000-4-5 surges, preserving load switch integrity and avoiding latch-up or gate oxide rupture. |
| IoT Edge Node Power Rail Protection | Robotic Actuator Control Interface |
|
Use Scenario: Securing 22V auxiliary power inputs in battery-backed wireless sensors deployed in outdoor or factory-floor environments. IC Role / Device Role / Timing Role: Standalone rail protector - installed directly at power entry point with minimal trace length to reduce inductive kick during fast transients. Use Value: Delivers ±30kV ESD immunity and stable clamping across −40°C to +85°C operating range, ensuring uptime in uncontrolled ambient conditions. |
Use Scenario: Safeguarding motor driver enable and feedback lines in collaborative robots exposed to EFT bursts from nearby switching loads. IC Role / Device Role / Timing Role: Signal-line transient limiter - placed on 22V-rated control bus segments carrying position/speed commands to servo drives. Use Value: Withstands ±4kV EFT (IEC 61000-4-4) without degradation, preventing spurious shutdowns or erroneous motion commands during electromagnetic noise events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Same 22V VRWM, identical 27.5–28V clamping at 40A, DFN-6 package, but commercial-grade (−40°C to +125°C, non-military screening) | Approved for industrial and consumer USB-C designs; lacks MIL-PRF-19500 qualification and JANTXV screening | Select for cost-sensitive, non-military programs requiring identical electrical performance and footprint. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V clamping at 40A, higher dynamic resistance (~0.5Ω), SO-201 package | Higher clamping voltage increases risk of downstream IC damage; larger footprint and lower surge endurance | Use only where legacy design constraints prevent DFN adoption and clamping margin >13V is acceptable. |
Compared with TDS2211P and SMAJ22A, JANTXV1N6475US provides identical clamping performance and compact packaging as TDS2211P but adds military-grade reliability screening, while offering significantly lower clamping voltage and superior thermal stability versus SMAJ22A's conventional TVS architecture.

FAQ
What is the clamping voltage specification for JANTXV1N6475US at maximum rated surge current?
JANTXV1N6475US clamps at 27.5–28 V when subjected to a 40 A peak pulse current with an 8/20 μs waveform. This value is guaranteed across the full operating temperature range (−40°C to +125°C) and reflects its FET-based constant-clamp architecture - a key differentiator from conventional TVS diodes whose clamping rises linearly with current.
Does JANTXV1N6475US meet IEC 61000-4-5 surge immunity requirements?
Yes, JANTXV1N6475US is rated for 40 A (8/20 μs) and ±1 kV (1.2/50 μs, RS = 42 Ω) per IEC 61000-4-5, making it suitable for Level 4 industrial surge protection. Its low dynamic resistance (20 mΩ) and stable clamping ensure compliance without derating at elevated temperatures - critical for DIN-rail mounted PLCs and outdoor IoT gateways.
How does JANTXV1N6475US differ from standard TVS diodes like SMAJ22A?
JANTXV1N6475US uses a surge-rated FET and precision trigger circuit instead of a PN junction, delivering near-constant clamping (27.5–28 V) across 24–40 A and −40°C to +125°C. In contrast, SMAJ22A exhibits rising clamping (>35 V at 40 A) and significant thermal drift - increasing risk of downstream IC damage in high-temperature or high-surge environments.
What is the recommended PCB layout for optimal performance of JANTXV1N6475US?
Place JANTXV1N6475US as close as possible to the protected connector. Connect all three GND pins (1, 2, 3) to a solid ground plane using multiple vias, and tie all three IN pins (4, 5, 6) together with a short, wide trace. Avoid thermal pads - energy is dissipated in the FET channel, not the junction. This layout minimizes inductance and ensures full 40 A surge capability.
Is JANTXV1N6475US suitable for protecting USB Type-C VBUS lines in PD applications?
Yes, JANTXV1N6475US is explicitly validated for USB Type-C VBUS protection in systems with up to 20 V PD negotiation. Its 22 V working voltage, 27.5 V clamping, and ±30 kV ESD rating meet USB-IF and IEC 61000-4-2 requirements. It protects PD controllers and load switches more reliably than standard TVS diodes, especially at elevated ambient temperatures.
