Product details
Overview
JAN1N6469US 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 JAN1N6469US datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, real-world clamping behavior vs. conventional TVS, and validated alternatives for 22V bus protection in USB PD, IoT, and industrial equipment designs.
Technical Context
The JAN1N6469US uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events and rapidly shunts transient current to ground. Unlike standard TVS diodes, its clamping voltage remains nearly constant due to ultra-low dynamic resistance (20mΩ) and decreasing RDS(on) under surge conditions.
It operates across –40°C to +125°C with reverse stand-off voltage of 22V, breakdown at 25–27.9V, and junction capacitance of 175pF at 22V/1MHz - enabling robust protection without signal integrity degradation on moderate-speed power/data lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold during surge events. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD immunity standards for connector-facing protection. |
| Dynamic Resistance | 20mΩ - enables flat clamping response and minimal voltage rise under increasing surge current. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for USB PD VBUS and load switch inputs, but not suitable for high-speed data lanes. |
| Leakage Current | 130–600nA at 22V - negligible power loss and thermal impact in always-on 22V supply rails. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS-compliant, UL 94V-0 molding compound. Exposed pad not present; all six terminals are signal/ground pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to maximize current handling and minimize inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., VBUS or load switch VIN); parallel connection ensures uniform current sharing and full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage stays within 27.5–28V from 24A to 40A and –40°C to +125°C - eliminates derating uncertainty in thermal design. |
| FET-based shunt topology | Replaces PN-junction TVS with <0.1Ω effective RDS(on), reducing energy dissipation in silicon junction and improving reliability under repeated surges. |
| Low dynamic resistance | 20mΩ measured between 1A–40A (8/20μs) - ensures minimal IR drop and predictable voltage limiting independent of surge magnitude. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz) - protects against burst noise in industrial control and motor drive environments. |
| Space-optimized footprint | 1.6mm × 1.6mm DFN saves >60% board area vs. comparable SO-8 or SOT-23 TVS solutions - critical for compact USB-C and IoT modules. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Front-End Protection |
|---|---|
|
Use Scenario: Protecting the VBUS line of a USB-C port supporting up to 20V/5A PD negotiation, exposed to ESD from hot-plug and lightning-induced surges on factory floor equipment. IC Role / Device Role / Timing Role: Transient diverting suppressor placed directly at the connector, clamping overvoltage before it reaches the PD controller and buck converter. Use Value: Maintains 27.5–28V clamping across temperature - avoids false OVP trips and guarantees controller survival where standard TVS would exceed 35V at 125°C. |
Use Scenario: Securing the input of an industrial-grade load switch (e.g., HS2950P) powering sensors or actuators in remote metering or robotics systems. IC Role / Device Role / Timing Role: Primary EOS barrier absorbing 40A surges from inductive kickback or AC-coupled transients on 22V supply rails. Use Value: Prevents internal FET failure in the load switch by holding clamp voltage well below its absolute maximum drain-source rating (typically 30–36V). |
| IoT Edge Device Power Bus Protection | Storage Device 22V Auxiliary Rail Protection |
|
Use Scenario: Safeguarding the main 22V input rail of a battery-backed smart gateway exposed to ESD during field servicing and conducted surges via PoE-derived supplies. IC Role / Device Role / Timing Role: Standalone transient suppressor on the primary power entry point, coordinated with upstream fuse and downstream LDO. Use Value: Delivers ±30kV ESD and 40A surge capability in 2.56mm² footprint - enabling ruggedized enclosure design without external heatsinking or oversized TVS arrays. |
Use Scenario: Protecting auxiliary 22V rails in NVMe SSD enclosures or enterprise HDD backplanes subjected to hot-swap transients and system-level ESD coupling. IC Role / Device Role / Timing Role: Point-of-load suppressor placed adjacent to connector or power multiplexer IC to limit voltage overshoot during insertion/removal. Use Value: 175pF capacitance avoids resonance with typical PCB trace inductance (<10nH), ensuring clean clamping response without ringing on 22V bias networks. |
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 (T22); JAN1N6469US is military-grade screened version per MIL-PRF-19500/560. | Qualified for extended temperature (-55°C to +150°C storage) and enhanced reliability screening (burn-in, lot acceptance tests). | Select JAN1N6469US for aerospace, defense, or high-reliability industrial programs requiring MIL-spec conformance; TDS2211P.C suffices for commercial USB-C and IoT use. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.3A; higher clamping, no constant-voltage behavior, 10× higher dynamic resistance (~200mΩ). | Limited to lower-energy transients; unsuitable for 40A surges or high-temperature operation where clamping rises above 40V. | Use SMAJ22A only in cost-sensitive, non-critical 22V applications with <15A surge requirement and ambient <85°C - not a functional replacement. |
Compared with JAN1N6469US, TDS2211P.C offers identical protection performance with commercial qualification, while SMAJ22A provides basic TVS-level clamping at lower cost but fails to meet 40A/125°C requirements - making JAN1N6469US the sole solution for high-reliability 22V surge immunity with flat clamping.

FAQ
What is the key functional distinction between JAN1N6469US and standard TVS diodes?
JAN1N6469US uses a triggered FET shunt architecture instead of a PN junction, delivering near-constant 27.5–28V clamping from 24A to 40A and –40°C to +125°C - unlike TVS diodes whose clamping voltage rises linearly with current and temperature. This makes JAN1N6469US uniquely suited for protecting sensitive 22V ICs like USB PD controllers under worst-case thermal and surge conditions.
Does JAN1N6469US require a thermal pad or heatsink for 40A surge handling?
No. JAN1N6469US dissipates surge energy primarily through its low-RDS(on) FET channel rather than a thermally limited PN junction, and its DFN-6 package is rated for full 40A (8/20μs) without external thermal relief. The datasheet explicitly states "no thermal pad is needed," and layout guidelines emphasize low-inductance grounding over copper pour area.
Can JAN1N6469US protect high-speed data lines such as USB SuperSpeed or PCIe?
No. With 175pF junction capacitance at 22V, JAN1N6469US is intended for power or low-speed signal lines (e.g., VBUS, CC, SBU, load switch inputs). For USB SS or PCIe lanes, Semtech recommends sub-0.25pF devices like RClamp3371ZC - using JAN1N6469US on those lines would severely degrade signal integrity.
What is the significance of the "JAN" prefix in JAN1N6469US?
The "JAN" prefix denotes Joint Army-Navy specification compliance - indicating JAN1N6469US is manufactured and tested to MIL-PRF-19500/560 for enhanced reliability, extended temperature range (–55°C to +150°C storage), and rigorous screening including burn-in and lot acceptance testing. It is the military-grade variant of the commercial TDS2211P.C.
How should the six pins of JAN1N6469US be routed on PCB for optimal surge performance?
All three GND pins (1, 2, 3) must connect to a solid ground plane using multiple vias; all three IN pins (4, 5, 6) must tie together with a short, wide trace directly from the protected connector. Separating or omitting any pin reduces peak current rating and increases clamping voltage - the datasheet mandates full pin connection to achieve the rated 40A capability.
