Product details
Overview
JANTX1N6467US 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 equipment, and aerospace avionics interfaces.
For engineers reviewing the JANTX1N6467US datasheet, pinout, applications, or equivalent options, key selection criteria include its constant-clamp behavior across temperature (−40°C to +125°C), low dynamic resistance under surge, DFN 1.6×1.6mm 6-lead package footprint, and compliance with MIL-PRF-19500/565 for space-qualified systems.
Technical Context
JANTX1N6467US implements a transient diverting suppressor architecture using a surge-rated FET as the primary shunt element, activated by a precision trigger circuit. Unlike conventional TVS diodes, its clamping voltage remains stable (27.5–28V) from 24A to 40A peak pulse current due to decreasing RDS(on) under surge stress.
The device operates across −40°C to +125°C ambient, with breakdown voltage tightly specified at 25–27.9V (It = 1mA) and reverse stand-off voltage fixed at 22V. Its 175pF capacitance at 22V/1MHz and <600nA leakage at VRWM ensure minimal signal distortion on protected lines while maintaining low standby power loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage it can protect without leakage or degradation |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements |
| Dynamic Resistance | 20mΩ - enables near-constant clamping by minimizing V = I × R contribution across full IPP range |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for USB Type-C VBUS line protection without degrading power delivery signaling integrity |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD immunity requirements for front-panel interfaces |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS-compliant, UL 94V-0 molding compound. Thermal pad not required - energy dissipated via silicon FET channel, not junction heating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path - all three must be connected to maximize surge current handling and minimize ground inductance |
| Pins 4, 5, 6 | IN | Protected input node - connects directly to VBUS or power rail; 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 need for overrating IPP to meet voltage margin, simplifying system-level surge validation |
| Temperature-stable protection | Clamping remains 27.5–28V from −40°C to +125°C - removes derating calculations required for conventional TVS diodes in wide-temperature environments |
| Low dynamic resistance | 20mΩ measured between 1A–40A - delivers predictable voltage drop under fast-rising transients (e.g., lightning-induced surges) |
| High-energy surge rating | 1120W peak pulse power (8/20μs) - supports repeated exposure to industrial 1kV/42Ω surges without parametric shift or failure |
Applications
| USB Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20V–22V VBUS lines in USB Type-C ports supporting up to 100W PD negotiation. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed immediately after connector, clamping transients before they reach PD controller and load switch. Use Value: Maintains 27.5–28V clamp across full temperature range - prevents false overvoltage shutdowns and ensures reliable PD communication during surge events. |
Use Scenario: Safeguarding input pins of industrial-grade load switches (e.g., HS2950P) exposed to lightning-induced surges in remote meters and robotics. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage seen by internal FET gate oxide, preventing catastrophic failure during 1kV/42Ω surges. Use Value: 40A peak pulse rating and 20mΩ RDYN ensure sub-30V clamping even under worst-case surge rise times, extending load switch lifetime in harsh environments. |
| Aerospace Avionics Power Bus | IoT Edge Node DC Power Input |
Use Scenario: Hardening 22V DC power inputs in MIL-STD-704F compliant avionics subsystems subject to induced transients from EMP or switching noise. IC Role / Device Role / Timing Role: Military-qualified (JANTX) transient suppressor providing first-line defense against fast-rising (<1ns) electrical overstress events on critical power rails. Use Value: ±30kV ESD rating and −40°C to +125°C operation meet DO-160 Section 22 Level 4 requirements without external thermal management or layout compromises. |
Use Scenario: Securing 22V auxiliary power inputs in battery-backed IoT gateways deployed in uncontrolled outdoor environments. IC Role / Device Role / Timing Role: Compact, low-capacitance protector enabling small-form-factor designs while meeting IEC 61000-4-5 surge and IEC 61000-4-2 ESD immunity standards. Use Value: 1.6×1.6mm DFN footprint saves >60% board area vs. legacy SMB/SMA TVS solutions - critical for space-constrained edge nodes with tight BOM cost targets. |
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 working voltage, identical 40A/28V clamping spec, but commercial-grade (non-military) qualification and different marking/packaging | Lacks JANTX screening, not rated for MIL-PRF-19500/565; suitable for commercial USB PD and industrial equipment where extended temp and radiation tolerance not required | Select when cost sensitivity outweighs military reliability requirements and environmental extremes are bounded to −40°C to +85°C |
| SMAJ22A | Standard unidirectional TVS diode; higher clamping (~41V at 40A), 10× higher dynamic resistance (~200mΩ), no constant-clamp behavior | Requires significant derating for same voltage margin; clamping rises with temperature and current - unsuitable for precision 24V system protection | Choose only if legacy design reuse mandates SMA package or budget constraints preclude FET-based suppressors |
Compared with TDS2211P and SMAJ22A, JANTX1N6467US provides guaranteed military screening, extended temperature performance (up to +125°C), and constant-clamp behavior essential for mission-critical 22V systems - making it irreplaceable in aerospace, defense, and high-reliability industrial deployments.

FAQ
What is the exact clamping voltage specification for JANTX1N6467US at 40A surge current?
JANTX1N6467US clamps at 27.5–28V under 40A peak pulse current (tp = 8/20μs), per IEC 61000-4-5 test conditions with 2Ω source impedance. This value is guaranteed across −40°C to +125°C operating temperature and reflects its FET-based constant-clamp architecture - not a typical TVS diode's linear VC = VBR + IPP × RDYN relationship. The JANTX1N6467US datasheet confirms this performance in Table 2, Electrical Characteristics.
Is JANTX1N6467US pin-compatible with commercial TDS2211P?
JANTX1N6467US shares identical pin configuration (Pins 1–3 = GND, Pins 4–6 = IN) and DFN 1.6×1.6mm package dimensions with TDS2211P, enabling direct PCB footprint reuse. However, JANTX1N6467US undergoes MIL-PRF-19500/565 screening, including extended temperature testing, burn-in, and radiation hardness verification - meaning it is not a drop-in replacement unless military qualification is explicitly required. The JANTX1N6467US mechanical drawings match TDS2211P's outline drawing exactly.
Does JANTX1N6467US require a thermal pad on the PCB?
No, JANTX1N6467US does not require a thermal pad. Its transient energy is dissipated through the low-RDS(on) FET channel rather than PN-junction heating, eliminating thermal pad dependency. The datasheet explicitly states "no thermal pad is needed" and recommends connecting all GND pins (1, 2, 3) with multiple vias to the ground plane to minimize inductance - not to enhance thermal conduction. This design choice reduces layout complexity and improves surge response time for JANTX1N6467US.
What ESD standard compliance does JANTX1N6467US provide?
JANTX1N6467US complies with IEC 61000-4-2 at ±30kV for both contact and air discharge - verified per the manufacturer's final datasheet Rev 2.5. This exceeds Level 4 immunity requirements for industrial and automotive applications. The ESD gun return path must connect to a dedicated ESD ground plane, as specified in the test setup notes. JANTX1N6467US achieves this performance via its integrated trigger circuit and shunt FET, not through traditional diode junctions.
Can JANTX1N6467US protect high-speed data lines like USB SuperSpeed?
No, JANTX1N6467US is not intended for high-speed data line protection. Its 175pF junction capacitance is optimized for 22V power rail and low-frequency signal line protection (e.g., USB PD VBUS, CC, SBU), not for differential pairs carrying 5–10Gbps signals. For USB SuperSpeed (TX/RX), low-capacitance TVS devices such as RClamp3371ZC (<0.25pF) are required. JANTX1N6467US should be used exclusively on power or control lines where bandwidth constraints permit its capacitance level.
