Product details
Overview
JANTX1N6461US.TR 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), 27.5–28V clamping voltage at 40A, and 20mΩ dynamic resistance - deployed in USB PD, Type-C, and industrial load-switch input protection.
For engineers reviewing the JANTX1N6461US.TR datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance for minimal voltage overshoot, DFN-6 package layout compatibility, and compliance with IEC 61000-4-2/4-4/4-5 surge standards.
Technical Context
The JANTX1N6461US.TR implements 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. 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.
It operates over –40°C to +125°C with stable junction capacitance (175pF @ 22V, 1MHz) and reverse leakage (<600nA @ 22V), and is rated for 1120W peak pulse power (8/20μs). Its functional architecture isolates protection energy dissipation into the FET channel rather than the junction, enabling superior thermal robustness versus standard TVS devices.
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 @ 40A (8/20μs) - ensures protected ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surge. |
| Peak Pulse Current | 40A (8/20μs) - supports compliance with IEC 61000-4-5 ±1kV (RS = 42Ω) industrial surge testing. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - eliminates need for secondary ESD stages in high-reliability interfaces. |
| Dynamic Resistance | 20mΩ - minimizes voltage rise ΔV = IPP × RDYN, critical for maintaining tight clamping across current range. |
| Junction Capacitance | 175pF @ 22V, 1MHz - low enough for 22V power rail protection without signal integrity impact on adjacent traces. |
Pinout & Package
Package: DFN-6 (1.6mm × 1.6mm × 0.55mm), RoHS-compliant, Pb-free, UL 94V-0 molding compound, tape-and-reel packaging.
| 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 inductance. |
| Pins 4, 5, 6 | IN | Protected line input (e.g., VBUS or load-switch input); parallel connection ensures uniform current sharing and optimal clamping performance. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage | 27.5–28V across full 24–40A IPP range and –40°C to +125°C - eliminates derating uncertainty in thermal design. |
| FET-based shunt architecture | Surge energy dissipated in low-RDS(on) channel instead of PN junction - enables higher reliability and longer lifetime under repeated surges. |
| Low dynamic resistance | 20mΩ - reduces clamping voltage rise under fast-rising transients, critical for protecting sensitive 22V-rated controllers. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz) - ensures robust operation in electrically noisy industrial environments. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load-Switch Input Protection |
|---|---|
Use Scenario: Protecting VBUS lines in USB-C ports supporting up to 20V PD, where transient overvoltage could damage PD controllers or port partner negotiation ICs. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed directly at connector, clamping surges before they reach downstream silicon. Use Value: Maintains 27.5–28V clamping across temperature and current - avoids over-clamping that risks PD controller latch-up or under-clamping that permits damage. |
Use Scenario: Safeguarding input pins of industrial-grade load switches (e.g., HS2950P) exposed to lightning-induced surges in remote meters, robotics, or factory automation. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage seen by the load switch's internal FET gate oxide and drain-source junction. Use Value: Prevents permanent degradation of the load switch by holding clamping voltage well below its absolute maximum ratings (e.g., <30V). |
| IoT Device Power Rail Protection | Storage Device 22V Bus Protection |
Use Scenario: Securing 22V auxiliary rails in battery-powered IoT gateways or edge nodes subject to ESD during field servicing or connector mating. IC Role / Device Role / Timing Role: Single-component, low-capacitance (175pF) protector for compact PCBs where space and BOM count are constrained. Use Value: Delivers ±30kV ESD immunity without requiring additional RC filtering or layout compromises typical of multi-stage TVS solutions. |
Use Scenario: Shielding 22V power inputs of NVMe SSD enclosures or enterprise storage backplanes from system-level surges during hot-swap or power sequencing events. IC Role / Device Role / Timing Role: High-power transient suppressor rated for 1120W peak pulse power, placed at board edge before bulk capacitance. Use Value: Handles 40A surge current without thermal runaway - sustains protection integrity during repetitive surge exposure in datacenter environments. |
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 | Same die, commercial-grade temperature range (–40°C to +85°C) vs. JANTX1N6461US.TR's military-grade (–55°C to +150°C junction temp). | Not qualified to MIL-PRF-19500/565; lacks JANTX screening, traceability, and extended temperature validation. | Select JANTX1N6461US.TR for aerospace, defense, or high-reliability industrial programs requiring MIL-spec qualification and lot traceability. |
| Littelfuse SP3022-01ETG | Standard TVS diode (not FET-based); clamping rises with current (VC ≈ VBR + IPP × RDYN); 33V min breakdown, 55V max clamping @ 40A. | Higher clamping voltage increases risk of downstream IC damage; less stable over temperature. | Choose JANTX1N6461US.TR where clamping stability, low dynamic resistance, and military screening are mandatory. |
Compared with TDS2211P.C and SP3022-01ETG, JANTX1N6461US.TR delivers constant 27.5–28V clamping across 40A and –55°C to +150°C, backed by MIL-PRF-19500/565 screening - making it uniquely suited for mission-critical 22V rail protection where thermal and surge margin cannot be compromised.

FAQ
What is the operating voltage rating of the JANTX1N6461US.TR?
The JANTX1N6461US.TR has a reverse stand-off voltage (VRWM) of 22V, meaning it remains non-conductive under normal 22V DC operation while providing protection against transients exceeding this threshold. This matches common USB PD and industrial 22V bus requirements, and the device begins clamping only when voltage surpasses its 25–27.9V breakdown range.
How does the JANTX1N6461US.TR achieve constant clamping voltage across varying surge currents?
The JANTX1N6461US.TR uses a surge-rated FET as its main protection element, triggered by an internal precision circuit. As surge current increases, the FET's RDS(on) decreases, counteracting voltage rise - resulting in stable 27.5–28V clamping from 24A to 40A. This differs fundamentally from TVS diodes, whose clamping rises linearly with current.
What is the package type and pin configuration of the JANTX1N6461US.TR?
JANTX1N6461US.TR is housed in a 1.6mm × 1.6mm × 0.55mm DFN-6 package with pins 1–3 assigned to GND and pins 4–6 assigned to IN. All six pins must be soldered - no floating terminals - to ensure full 40A surge capability and minimal parasitic inductance in the ground return path.
Is the JANTX1N6461US.TR compliant with international surge immunity standards?
Yes, JANTX1N6461US.TR meets IEC 61000-4-2 (±30kV ESD), IEC 61000-4-4 (±4kV EFT), and IEC 61000-4-5 (40A 8/20μs, ±1kV 1.2/50μs) standards. Its 1120W peak pulse power rating and stable clamping enable direct compliance without external components in most 22V system-level tests.
What distinguishes JANTX1N6461US.TR from commercial-grade TDS devices like TDS2211P.C?
JANTX1N6461US.TR is the JANTX-qualified version of Semtech's TDS2211P, screened per MIL-PRF-19500/565 with extended junction temperature range (–55°C to +150°C), enhanced lot traceability, and rigorous environmental stress testing - unlike TDS2211P.C, which is rated only for –40°C to +85°C and lacks military screening.
