Product details
Overview
JAN1N6472US 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 ultra-low 20mΩ dynamic resistance. It protects USB PD, USB Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the JAN1N6472US datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DFN-6 package layout guidance, real-world clamping stability across temperature and current, and direct alternatives for 22V bus protection design.
Technical Context
The JAN1N6472US 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. Unlike conventional TVS diodes, its clamping voltage remains nearly constant-27.5–28V-from 24A to 40A and across –40°C to +125°C due to decreasing RDS(on) under surge.
It operates with reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V, and junction capacitance of 175pF at 22V/1MHz. Its 6-pin DFN package integrates three parallel input terminals (pins 4–6) and three ground terminals (pins 1–3), requiring all pins to be connected for full 40A rating and minimal parasitic inductance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V reverse stand-off-supports nominal 20V USB PD VBus without leakage or false triggering. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo waveform)-holds below 28V across full surge range, protecting 30V-tolerant controllers. |
| Peak Pulse Current | 40A (8/20μs)-meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment interfaces. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2)-exceeds Level 4 requirements for handheld and connector-exposed designs. |
| Dynamic Resistance | 20mΩ (8/20μs, 1–40A)-enables flat clamping curve and minimizes voltage overshoot during fast transients. |
| Junction Capacitance | 175pF at 22V/1MHz-compatible with DC/low-speed power rails; not intended for high-speed data lines. |
| Operating Temp | –40°C to +125°C-maintains stable clamping and leakage (<600nA) across automotive and industrial ambient ranges. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Three parallel ground terminals-must all be connected to low-inductance ground plane via multiple vias for full 40A surge handling. |
| Pins 4, 5, 6 | IN | Three parallel input terminals-connect directly to protected line (e.g., USB PD VBus); all must be routed together to minimize imbalance. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage stays within 27.5–28V from 24A to 40A-eliminates derating needed with traditional TVS diodes. |
| FET-based shunt protection | Surge energy diverted through low-RDS(on) FET-not dissipated in PN junction-enabling higher reliability at elevated temperatures. |
| Multi-terminal parallel layout | Three-input/three-ground configuration reduces effective trace inductance and distributes surge current, improving robustness vs. single-pin devices. |
| Temperature-stable performance | Clamping voltage variation <0.5V from –40°C to +125°C-enables predictable protection in uncontrolled thermal environments. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20V USB PD VBus lines against lightning surges, ESD, and EOS events in docking stations and host controllers. IC Role / Device Role / Timing Role: Transient diverting suppressor placed at connector entry point to clamp overvoltage before reaching PD controller ICs. Use Value: Maintains clamping at ≤28V across full 40A surge and –40°C to +125°C-prevents damage to 30V-rated PD controllers without over-spec'ing IPP. |
Use Scenario: Safeguarding enable and input pins of high-side load switches (e.g., HS2950P) in remote meters and robotics. IC Role / Device Role / Timing Role: Primary front-end EOS protector for load switch VIN/EN nodes exposed to field wiring transients. Use Value: Limits clamping to 28V-below typical 30–36V FET drain-source breakdown-preserving switch integrity during 1kV/42Ω surges. |
| IoT Device Power Rail Protection | Notebook/Tablet DC Power Input Protection |
Use Scenario: Securing 12–24V DC input rails in battery-powered IoT gateways subjected to ESD during hot-plug or connector mating. IC Role / Device Role / Timing Role: Solid-state transient suppressor replacing bulkier TVS arrays on main power entry points. Use Value: 1.6×1.6mm DFN footprint saves >60% board area vs. discrete 22V TVS solutions while delivering superior clamping consistency. |
Use Scenario: Protecting adapter-input power paths in thin client notebooks where space and thermal margin are constrained. IC Role / Device Role / Timing Role: Single-component 22V rail protector for AC/DC adapter interface, co-located with input capacitor. Use Value: 20mΩ dynamic resistance ensures minimal voltage rise during fast 8/20μs surges-reducing risk of upstream regulator latch-up or brownout. |
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 | Identical electrical specs, same DFN-6 package, and identical marking code "T22"-JAN1N6472US is the military-grade qualified variant of TDS2211P.C. | TDS2211P.C is commercial-grade; JAN1N6472US meets MIL-PRF-19500/560 requirements for screening and environmental testing. | Select JAN1N6472US for defense, aerospace, or high-reliability industrial programs requiring extended temperature validation and lot traceability. |
| SMAJ22A | Standard 22V unidirectional TVS diode; clamps at ~38V @ 24A (125°C), 600mΩ dynamic resistance, 1000W peak power, DO-214AC package. | Larger footprint (4.3×2.6mm), higher clamping, and strong temperature dependence-requires derating above 85°C. | Choose SMAJ22A only if legacy board space allows larger package and clamping >35V is acceptable for downstream components. |
Compared with TDS2211P.C, JAN1N6472US offers identical protection performance with enhanced reliability screening; versus SMAJ22A, it delivers 10.5V lower clamping at full surge, 30× lower dynamic resistance, and 75% smaller footprint-making it optimal for space-constrained, thermally aggressive, or high-reliability 22V rail protection.

FAQ
What is the key functional difference between JAN1N6472US and standard TVS diodes?
JAN1N6472US uses a surge-rated FET and precision trigger circuit instead of a PN junction, resulting in near-constant 27.5–28V clamping from 24A to 40A and minimal variation across –40°C to +125°C. Standard TVS diodes exhibit rising clamping voltage with increasing current and temperature due to fixed dynamic resistance-JAN1N6472US avoids this limitation entirely.
Does JAN1N6472US require external bias or control signals to operate?
No. JAN1N6472US is fully passive and self-triggering: it activates automatically when transient voltage exceeds its internal breakdown threshold (~25–27.9V). No external power, enable pins, or configuration are needed-JAN1N6472US functions as a two-terminal device with pins 1–3 as GND and pins 4–6 as IN.
Can JAN1N6472US be used on high-speed data lines like USB SuperSpeed or PCIe?
No. With 175pF junction capacitance at 22V, JAN1N6472US is intended solely for DC or low-frequency power and control lines-not signal integrity-critical data paths. For USB SS, DP/DM, or CC lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF) or uClamp2411ZA-JAN1N6472US must be used only on VBus or load switch inputs.
What PCB layout practices are critical for achieving full 40A surge rating with JAN1N6472US?
To achieve rated 40A performance, all three GND pins (1–3) must connect to a solid ground plane using ≥3 vias each, and all three IN pins (4–6) must be routed as a single low-inductance trace from the connector. JAN1N6472US must be placed within 5mm of the protected port-any longer trace adds series inductance that degrades clamping response and increases overshoot.
Is JAN1N6472US compatible with lead-free reflow soldering processes?
Yes. JAN1N6472US uses Pb-free terminations and is qualified for standard JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260°C. Its DFN package has UL 94V-0 flammability rating and withstands multiple reflow cycles without degradation-JAN1N6472US supports automated SMT assembly in high-volume production.
