Product details
Overview
JANTXV1N6464US from Microsemi (now Microchip) is a military-grade transient voltage suppression diode designed for high-reliability EOS/ESD protection of 22V-rated 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 equipment, and aerospace avionics interfaces.
For engineers reviewing the JANTXV1N6464US datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DFN-6 package layout guidance, clamping stability across temperature, and direct alternatives for MIL-PRF-19500/563-compliant designs requiring 22V working voltage and low-inductance surge diversion.
Technical Context
JANTXV1N6464US implements a transient diverting architecture using a surge-rated FET as the primary shunt element, activated by a precision trigger circuit that senses overvoltage events above 25V breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant (27.5–28V) from 24A to 40A due to decreasing RDS(on) under surge conditions.
The device operates across –55°C to +150°C junction temperature, maintains stable 22V reverse stand-off voltage, and achieves <600nA leakage at VRWM. Its 175pF capacitance at 22V/1MHz and 20mΩ dynamic resistance support high-speed line protection without signal integrity degradation in USB Type-C and industrial bus applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - limits transient voltage seen by downstream ICs to safe levels during lightning/surge events. |
| Peak Pulse Current | 40A (8/20μs) - supports compliance with IEC 61000-4-5 Level 4 industrial surge immunity testing. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - protects against human-body-model and system-level electrostatic discharge. |
| Dynamic Resistance | 20mΩ - ensures minimal voltage rise under high-current transients, enabling tighter clamping control than TVS diodes. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for USB PD and industrial data lines without signal distortion or bandwidth loss. |
| Operating Temperature | –55°C to +150°C - qualified for extended-range military, aerospace, and harsh-environment embedded systems. |
Pinout & Package
Package: DFN-6 (1.6mm × 1.6mm × 0.55mm), RoHS-compliant, UL 94V-0 molding compound, lead-free finish, tape-and-reel packaging (3,000 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to minimize inductance and maximize 40A capability. |
| Pins 4, 5, 6 | IN | Protected line input - connects directly to VBus or signal line; parallel connection ensures uniform current sharing and thermal distribution. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A - eliminates design margin inflation required with traditional TVS diodes. |
| Temperature-stable protection | Clamping remains 27.5–28V from –40°C to +125°C - enables reliable operation in uncontrolled thermal environments. |
| Low dynamic resistance | 20mΩ measured between 1A–40A - reduces power dissipation and localized heating during multi-pulse surge events. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) - exceeds MIL-STD-1275E and DO-160 Section 22 surge requirements. |
| Small-footprint DFN | 1.6mm × 1.6mm area - saves >60% board space vs. SO-8 or SMC packages while maintaining full 40A surge handling. |
Applications
| USB Type-C Power Delivery | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20V–22V VBus lines in USB-C receptacles exposed to ESD, hot-plug transients, and fault-induced surges. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed adjacent to connector, diverting surge energy to ground before reaching PD controller or load switch. Use Value: Maintains 27.5V clamping at full 40A even at 125°C - prevents damage to USB PD controllers rated for ≤28V absolute maximum. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and factory automation systems. IC Role / Device Role / Timing Role: Front-end transient diverter that clamps voltage below the internal FET's drain-source breakdown rating during lightning-induced surges. Use Value: Enables use of lower-cost, higher-integration load switches by eliminating need for external series impedance or oversized TVS devices. |
| Avionics Data Bus Interfaces | IoT Edge Node Power Rails |
Use Scenario: Hardening ARINC 429, MIL-STD-1553, or CAN FD power rails in airborne electronics subject to DO-160 Section 22 induced transients. IC Role / Device Role / Timing Role: Single-device solution for 22V rail protection with guaranteed performance across –55°C to +125°C operational range. Use Value: Meets MIL-PRF-19500/563 screening requirements and eliminates derating concerns in high-temperature avionics bays. |
Use Scenario: Securing 12–24V power inputs of battery-powered IoT gateways and sensor nodes deployed in unshielded outdoor enclosures. IC Role / Device Role / Timing Role: Standalone surge protector replacing multi-component TVS+filter networks on compact PCBs with limited real estate. Use Value: Reduces BOM count by 2–3 components while improving clamping consistency and long-term reliability under repeated EFT exposure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Commercial-grade, same 22V/40A/27.5V spec, DFN-6 package, non-military screening. | Qualified per AEC-Q200; suitable for automotive infotainment and industrial IoT but not MIL-PRF-19500. | Select when commercial qualification and cost sensitivity outweigh military screening requirements. |
| SMCJ22A | Standard TVS diode; 22V VRWM, 35.5V VC @ 32.4A, higher clamping, larger SMC package. | Larger footprint, higher clamping voltage increases risk of downstream IC damage at elevated temperatures. | Choose only if legacy design reuse or availability constraints prevent adoption of FET-based TDS architecture. |
Compared with TDS2211P and SMCJ22A, JANTXV1N6464US provides military-grade reliability, tighter clamping (27.5V vs. 35.5V), and smaller DFN-6 footprint - making it optimal for space-constrained, high-assurance systems where surge consistency across temperature and lifetime is critical.

FAQ
What is the exact package type and dimensions of JANTXV1N6464US?
JANTXV1N6464US uses a DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed pad-less construction. Pins 1–3 are GND terminals and pins 4–6 are IN terminals; all six pins must be soldered to achieve full 40A surge rating and thermal performance. The package is RoHS-compliant and UL 94V-0 rated.
How does JANTXV1N6464US differ from standard TVS diodes in clamping behavior?
JANTXV1N6464US uses a FET-based transient diverting architecture instead of a pn-junction, resulting in near-constant clamping voltage (27.5–28V) across its entire 24–40A surge range and from –55°C to +150°C. Standard TVS diodes exhibit linear clamping rise (e.g., VC = VBR + IPP × RDYN), increasing risk of downstream IC damage at high currents or temperatures.
Is JANTXV1N6464US suitable for protecting USB PD 3.0 VBus lines?
Yes - JANTXV1N6464US is explicitly validated for USB PD applications with up to 22V nominal VBus. Its 27.5V clamping at 40A ensures protected PD controllers remain within their 28V absolute maximum rating, even under worst-case 125°C ambient conditions and full IEC 61000-4-5 surge stress.
What is the maximum junction temperature and thermal derating profile for JANTXV1N6464US?
JANTXV1N6464US has a maximum junction temperature of +150°C and storage temperature range of –55°C to +150°C. Electrical parameters including clamping voltage and leakage current are characterized across this full range; no thermal derating of peak pulse current is required - the 40A rating holds from –55°C to +125°C ambient.
Does JANTXV1N6464US require external biasing or control signals to operate?
No - JANTXV1N6464US is a fully passive, self-triggering device. It requires no external power, enable signals, or configuration. The integrated precision trigger circuit activates the shunt FET automatically when input voltage exceeds ~25V, providing immediate protection without firmware or timing dependencies.
