Product details
Overview
JANTXV1N6469US from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection on 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, and ultra-low 20mΩ dynamic resistance - deployed in USB PD, USB Type-C, and industrial load switch input protection.
For engineers reviewing the JANTXV1N6469US datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature (−40°C to +125°C), DFN-6 package footprint (1.6 × 1.6 mm), low 175pF junction capacitance, and solid-state FET-based shunt architecture enabling constant-voltage clamping unlike conventional TVS diodes.
Technical Context
The JANTXV1N6469US implements a precision-triggered surge-rated MOSFET as its primary protection element, activated by an internal reference circuit when transient voltage exceeds breakdown threshold. Unlike standard TVS diodes, its clamping voltage remains nearly constant (27.5–28V) from 24A to 40A due to decreasing RDS(on) under surge conditions.
It operates over −40°C to +125°C ambient, with reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V at 1mA, and leakage current ≤600nA at VRWM. Its 2Ω source impedance compatibility enables compliance with IEC 61000-4-5 ±1kV unsymmetrical line testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage it can protect without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo waveform) - ensures protected ICs (e.g., USB PD controllers) remain below damage thresholds during surges. |
| Peak Pulse Current | 40A (8/20μs) - supports industrial-level surge immunity per IEC 61000-4-5, exceeding typical 20–30A requirements. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - eliminates need for secondary ESD stages in high-reliability interfaces. |
| Dynamic Resistance | 20mΩ - enables flat clamping curve and minimizes voltage overshoot during fast-rising transients. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for USB Type-C VBUS protection without signal integrity impact on adjacent high-speed lanes. |
Pinout & Package
Package: DFN-6 (1.6 mm × 1.6 mm × 0.55 mm), RoHS-compliant, Pb-free, UL 94V-0 molding compound, tape-and-reel packaging (3,000 units/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 maximize current handling and minimize parasitic inductance. |
| Pins 4, 5, 6 | IN | Protected line input (e.g., VBUS or load switch input); parallel connection ensures uniform current sharing and full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies <0.5V across 24–40A surge range - avoids overvoltage stress on downstream ICs under varying surge severity. |
| FET-based shunt topology | Replaces PN-junction TVS with low-RDS(on) MOSFET - dissipates energy in channel rather than junction, improving thermal robustness and lifetime. |
| Temperature-stable clamping | Clamping remains ~27.6V from −40°C to +125°C - eliminates derating concerns in automotive or industrial environments. |
| Low-capacitance protection | 175pF enables placement directly on high-current rails (e.g., USB PD VBUS) without degrading power integrity or coupling into adjacent signal traces. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBUS lines in USB-C ports supporting up to 100W PD, exposed to ESD and lightning-induced surges. IC Role / Device Role / Timing Role: Primary high-energy EOS suppressor placed at connector entry point, shunting transients before reaching PD controller and load switch. Use Value: Maintains 27.6V clamping at 40A and 125°C - prevents overvoltage damage to HS2950P or similar load switches and USB PD controllers that tolerate ≤28V max. |
Use Scenario: Safeguarding input terminals of industrial-grade e-fuses and load switches in remote meters, robotics, and factory automation equipment. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage seen by internal FET gate oxide and sense resistors during 1kV/42Ω surges. Use Value: 20mΩ dynamic resistance ensures minimal IR drop during clamping, preserving overvoltage protection margins for downstream monitoring circuits. |
| IoT Device Power Rail Protection | Storage Device VCC Line Protection |
Use Scenario: Securing 12–24V power inputs in battery-powered IoT edge nodes subjected to field ESD and induced surges in unshielded enclosures. IC Role / Device Role / Timing Role: Single-component solution replacing multi-stage TVS+MOV designs, reducing BOM count and PCB area. Use Value: 1.6×1.6mm DFN footprint saves >60% board space vs. SO-8 TVS alternatives while delivering superior clamping consistency. |
Use Scenario: Protecting 19–22V auxiliary rails in NVMe SSDs and enterprise storage controllers against hot-plug transients and backplane coupling. IC Role / Device Role / Timing Role: High-reliability rail clamp positioned between connector and DC-DC converter input, rated for repeated 40A surges. Use Value: ±30kV ESD rating meets stringent IEC 61000-4-2 Level 4 requirements for storage subsystems in data centers and industrial servers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Semtech TDS2211P.C | Identical electrical specs, same DFN-6 package, commercial-grade (−40°C to +85°C) vs. JANTXV1N6469US's military-grade −55°C to +125°C operation. | Not qualified to MIL-PRF-19500/560; lacks JANTXV screening, burn-in, and lot traceability required for aerospace/defense programs. | Select JANTXV1N6469US when extended temperature range, radiation hardness assurance, or military reliability testing is mandated. |
| Littelfuse SP3022-01FTG | TVS diode (not FET-based); higher 33V clamping at 30A, 350pF capacitance, no constant-clamp behavior - clamping rises with current and temperature. | Used where cost sensitivity outweighs clamping precision; requires additional thermal margining and derating above 85°C. | Choose only if legacy design uses standard TVS and board layout cannot accommodate revised clamping analysis. |
Compared with TDS2211P.C and SP3022-01FTG, JANTXV1N6469US delivers military-grade temperature resilience and true constant-voltage clamping - critical for mission-critical systems where transient response predictability and long-term reliability under thermal cycling are non-negotiable.

FAQ
What is the operating temperature range of JANTXV1N6469US?
JANTXV1N6469US is specified for operation from −55°C to +125°C, meeting MIL-PRF-19500/560 requirements for military and aerospace applications. This extended range ensures reliable clamping performance in extreme environments where commercial-grade suppressors (e.g., TDS2211P.C, rated −40°C to +85°C) would derate or fail.
How does JANTXV1N6469US achieve constant clamping voltage across surge current?
JANTXV1N6469US uses a precision-triggered surge-rated MOSFET instead of a PN junction. As peak pulse current increases from 24A to 40A, the FET's RDS(on) decreases, counteracting voltage rise - resulting in clamping voltage variation of only 0.5V (27.5–28V). This contrasts with TVS diodes whose VC = VBR + IPP × RDYN yields linear voltage increase.
Is JANTXV1N6469US pin-compatible with TDS2211P.C?
Yes - JANTXV1N6469US shares identical DFN-6 (1.6 × 1.6 mm) package dimensions, pin numbering (Pins 1–3 = GND; Pins 4–6 = IN), and land pattern with TDS2211P.C. However, JANTXV1N6469US undergoes military screening (JANTXV level), including extended temperature testing and lot traceability not present in the commercial variant.
What standards does JANTXV1N6469US meet for surge and ESD protection?
JANTXV1N6469US complies with IEC 61000-4-2 (±30kV contact/air ESD), IEC 61000-4-4 (±4kV EFT), and IEC 61000-4-5 (40A/8/20μs, ±1kV/1.2/50μs with 42Ω source). Its 22V working voltage and 27.6V clamping enable compliance with USB IF and industrial surge immunity specifications without external components.
Can JANTXV1N6469US be used for protecting high-speed data lines like USB SS or PCIe?
No - JANTXV1N6469US is intended for power or low-speed I/O lines (e.g., VBUS, CC, SBU, load switch inputs) due to its 175pF junction capacitance. For SuperSpeed USB or PCIe data lanes, Semtech recommends sub-0.3pF devices like RClamp3371ZC; JANTXV1N6469US would degrade signal integrity on those interfaces.
