Product details
Overview
JANTXV1N5811US from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), and stable 27.5–28V clamping across temperature and current range - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the JANTXV1N5811US datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under 40A surge, DFN-6 thermal and layout performance, low 20mΩ dynamic resistance, and compatibility with 22V bus systems requiring robust EOS resilience without TVS-like voltage drift.
Technical Context
The JANTXV1N5811US uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that turns on the shunt path when transient voltage exceeds breakdown - enabling near-constant clamping voltage independent of peak pulse current magnitude. Its operation avoids the linear VC = VBR + IPP × RDYN behavior typical of conventional TVS diodes.
Unlike standard TVS devices, the JANTXV1N5811US maintains clamping voltage within 27.5–28V from −40°C to +125°C and across 24A–40A surge currents (1.2/50μs voltage + 8/20μs current combination waveform, RS = 2Ω), due to decreasing RDS(on) under increasing current and minimal temperature coefficient of the trigger threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage of protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave, RS = 2Ω) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| Peak Pulse Current | 40A (tp = 8/20μs) - supports compliance with IEC 61000-4-5 Level 4 (±1kV, RS = 42Ω) on unsymmetrical lines. |
| ESD Withstand | ±30kV contact & air per IEC 61000-4-2 - enables direct interface with exposed connectors in handheld and portable equipment. |
| Dynamic Resistance | 20mΩ (measured 1A–40A, tp = 8/20μs) - contributes to flat clamping curve and low voltage overshoot during fast transients. |
| Junction Capacitance | 175pF at VR = 22V, f = 1MHz - suitable for DC/low-speed power rail protection; not intended for high-speed data lines. |
| Operating Temperature | −40°C to +125°C - supports deployment in industrial and automotive under-hood environments without derating. |
Pinout & Package
Package: DFN-6 (1.6mm × 1.6mm × 0.55mm), RoHS-compliant, Pb-free, UL 94V-0 molding compound, tape-and-reel packaging (3,000 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return for surge current; all three pins must be connected to maximize current handling and minimize parasitic inductance. |
| 4, 5, 6 | IN | Input terminal for protected bus (e.g., VBUS in USB PD); parallel connection of all three pins required for full 40A rating and optimal thermal distribution. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based shunt architecture | Enables constant clamping voltage over full 24–40A surge range - eliminates design margin inflation needed with traditional TVS diodes. |
| Low dynamic resistance | 20mΩ ensures minimal IR drop during high-current transients, preserving clamping accuracy and reducing localized heating. |
| Stable clamping vs. temperature | 27.5–28V clamping maintained from −40°C to +125°C - removes thermal derating calculations for industrial ambient conditions. |
| High-energy EOS protection | Rated for 1120W peak pulse power (8/20μs) - exceeds requirements for IEC 61000-4-5 Level 4 and MIL-STD-1275E transient suppression. |
| Compact DFN footprint | 1.6mm × 1.6mm area saves >60% board space versus SOT-23 or SOIC alternatives - critical for USB-C connector proximity placement. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20V–22V VBUS lines in USB-C receptacles against lightning-induced surges and hot-plug ESD events. IC Role / Device Role / Timing Role: Primary front-end EOS suppressor placed immediately after the connector, before the PD controller and load switch. Use Value: Maintains clamping at ≤28V across temperature and 40A surge - prevents latch-up or gate oxide damage in 24V-tolerant PD controllers like TUSB73x or CYPD3177. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P, TPS25982) in remote meters and robotics. IC Role / Device Role / Timing Role: Transient energy diversion device that limits voltage stress on the load switch's internal FET during 1.2/50μs surges. Use Value: Prevents overvoltage failure of the load switch's gate oxide and drain-source junction by clamping to 28V - extends reliability in ungrounded or floating supply environments. |
| IoT Edge Node Power Rail Protection | Storage Device DC Input Protection |
Use Scenario: Securing 12–24V DC inputs of battery-powered IoT gateways exposed to field ESD and induced surges. IC Role / Device Role / Timing Role: Standalone transient suppressor on main power entry point, upstream of DC-DC converters and PMICs. Use Value: Delivers ±30kV ESD immunity and 40A surge capability in <2.6mm² footprint - enables compact, ruggedized enclosure designs without external spark gaps or MOVs. |
Use Scenario: Protecting SATA or NVMe storage module 12V/19V inputs against power supply transients and backfeed surges in enterprise servers. IC Role / Device Role / Timing Role: High-power transient clamp on primary DC input rail, coordinated with low-capacitance TVS on signal lines. Use Value: Limits rail overshoot to 28V during 8/20μs surges - prevents overvoltage shutdown or latch-up in storage controller ICs such as ASM1083 or PCIe switch buffers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P.C | Same die, commercial-grade variant (−40°C to +85°C), identical electrical specs and pinout. | Lacks extended temperature qualification; not rated for industrial or automotive under-hood use. | Select JANTXV1N5811US for military/aerospace or extended-temp industrial deployments where 125°C operation is required. |
| SMAJ22A | Standard unidirectional TVS diode; clamping rises to ~42V at 40A; higher dynamic resistance (~0.5Ω); no temperature stability. | Higher clamping voltage risks damage to 24V-rated ICs at elevated ambient temperatures. | Only consider SMAJ22A if cost is primary constraint and system operates below 60°C with lower surge exposure. |
Compared with TDS2211P.C and SMAJ22A, JANTXV1N5811US delivers guaranteed 125°C operation, flat 28V clamping across full current and temperature range, and superior surge survivability - making it the only option qualified for mission-critical 22V rail protection where thermal and electrical margins are non-negotiable.

FAQ
What is the maximum continuous operating voltage for JANTXV1N5811US?
JANTXV1N5811US has a reverse stand-off voltage (VRWM) of 22V, meaning it remains non-conductive and exhibits ≤600nA leakage up to this DC or RMS voltage. Operation above 22V risks premature conduction and accelerated degradation; it is not rated for sustained overvoltage conditions beyond this limit.
Does JANTXV1N5811US require a thermal pad on the PCB?
No, JANTXV1N5811US does not require a thermal pad. Energy during transients is dissipated via the FET channel and package leads, not junction-to-case conduction. The datasheet explicitly states "no thermal pad is needed," and recommended layout focuses on low-inductance GND vias and direct IN trace routing instead.
Can JANTXV1N5811US be used on high-speed data lines like USB SS or PCIe?
No, JANTXV1N5811US is not suitable for high-speed data lines. Its 175pF junction capacitance would severely degrade signal integrity on SuperSpeed (5–10Gbps), PCIe, or DisplayPort channels. It is designed exclusively for DC or low-frequency power and control lines - low-capacitance devices like RClamp3371ZC must be used for data line protection alongside JANTXV1N5811US.
How does JANTXV1N5811US achieve constant clamping voltage across 40A surge current?
JANTXV1N5811US achieves constant clamping by using a surge-rated FET whose RDS(on) decreases under high current, counteracting the rise in voltage drop. Combined with a precision trigger circuit that activates at ~27.9V, the resulting clamping stays tightly bounded between 27.5V and 28V - unlike TVS diodes whose VC increases linearly with IPP due to fixed RDYN.
Is JANTXV1N5811US pin-compatible with standard SOT-23 or SOIC transient suppressors?
No, JANTXV1N5811US uses a proprietary 6-pin DFN-1616 package (1.6mm × 1.6mm) with dual 3-pin groupings (IN and GND). It is not pin-compatible with SOT-23, DO-214AC, or SOIC packages. Layout requires dedicated land pattern per Semtech's outline drawing - migration from legacy packages demands PCB redesign.
