Product details
Overview
JAN1N6470US 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 JAN1N6470US datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (DFN 1.6×1.6×0.55mm, 6-lead), confirmed electrical parameters (VRWM = 22V, VBR = 25–27.9V, VC = 27.5–28V @ 24–40A), thermal stability (–40°C to +125°C), and real-world use context in USB PD and load switch protection.
Technical Context
The JAN1N6470US 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 due to decreasing RDS(on) under surge, not fixed dynamic resistance.
It operates with three parallel input terminals (Pins 4–6) and three ground terminals (Pins 1–3), requiring all six pins to be connected for full 40A surge capability; its low 20mΩ dynamic resistance and 175pF junction capacitance at 22V support high-speed, low-distortion protection without signal integrity compromise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V reverse stand-off - defines maximum continuous bus voltage before conduction begins. |
| Breakdown Voltage | 25–27.9V at 1mA - precise threshold triggering the FET-based shunt mechanism. |
| Clamping Voltage | 27.5–28V at 24–40A (1.2/50μs + 8/20μs combo wave) - ensures protected ICs (e.g., USB PD controllers) stay below damage thresholds. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD requirements. |
| Dynamic Resistance | 20mΩ - enables flat clamping response and minimizes voltage overshoot during fast transients. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for USB PD power line protection without degrading rise/fall times. |
Pinout & Package
Package: DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead, Pb-free, RoHS-compliant, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path - all three must be connected to minimize inductance and maximize surge current handling. |
| Pins 4, 5, 6 | IN | Parallel-connected input terminals for protected bus - required for full 40A rating and optimal thermal distribution. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based shunt architecture | Enables near-constant clamping voltage over 24–40A and –40°C to +125°C - eliminates thermal derating uncertainty in industrial environments. |
| Triple-terminal input & ground | Distributes surge current across three parallel paths - reduces trace heating and PCB layout sensitivity vs. single-pin alternatives. |
| Low dynamic resistance (20mΩ) | Minimizes voltage overshoot during sub-microsecond ESD events - critical for protecting sensitive USB PD controller inputs. |
| 175pF junction capacitance | Preserves signal integrity on 22V power rails without filtering or bandwidth limitation - suitable for USB PD up to 100W. |
| UL 94V-0 flammability rating | Ensures safe operation under sustained overvoltage fault conditions - required for industrial and medical-grade power systems. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Front-End Protection |
|---|---|
Use Scenario: Protecting the VBUS line of a USB Type-C port supporting up to 20V/5A (100W) power delivery against lightning-induced surges and connector ESD. IC Role / Device Role / Timing Role: Transient diverting suppressor placed directly at the connector, clamping transients before they reach the PD controller and e-fuse. Use Value: Maintains clamping at ≤28V across temperature and current - prevents damage to 30V-rated PD controllers where conventional TVS would exceed 35V at 125°C. |
Use Scenario: Safeguarding the input of high-side load switches (e.g., HS2950P) in remote meters, robotics, and IoT gateways exposed to 1kV/42Ω surges per IEC 61000-4-5. IC Role / Device Role / Timing Role: Primary front-end protector absorbing >95% of surge energy, preventing gate oxide rupture and drain-source avalanche in the load switch FET. Use Value: 40A surge rating and 20mΩ RDS(on) ensure <100ns response and minimal voltage overshoot - avoids false OVP triggering and system reset. |
| IoT Device DC Power Rail Protection | Storage Device 22V Backup Power Line Protection |
Use Scenario: Securing 22V auxiliary power inputs in battery-backed smart sensors and edge nodes operating in electrically noisy factory environments. IC Role / Device Role / Timing Role: Solid-state EOS suppressor replacing bulkier MOV+TVS stacks - handles repetitive 24A surges without degradation. Use Value: Stable 27.5V clamping at –40°C ensures reliable protection during cold-start conditions where TVS devices exhibit elevated VC. |
Use Scenario: Protecting the 22V backup supply rail feeding NVMe SSD controllers and DRAM retention circuits in enterprise storage enclosures. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor preserving power-rail stability during hot-plug and EFT events. Use Value: 175pF capacitance avoids resonant peaking with bulk input capacitors - maintains clean 22V rail during 4kV EFT bursts (IEC 61000-4-4). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Same device - JAN1N6470US is the military-spec (JAN) variant of TDS2211P with identical electrical specs, DFN package, and pinout. | No functional difference; JAN1N6470US qualified to MIL-PRF-19500/560 for enhanced reliability screening. | Select JAN1N6470US for defense/aerospace programs requiring JAN-level qualification; TDS2211P suffices for commercial industrial use. |
| SMAJ22A | Standard unidirectional TVS diode; higher clamping (≈38V @ 24A, 125°C), fixed RDYN (~0.5Ω), no FET-based regulation. | Limited to lower-temperature or lower-surge applications where clamping voltage margin allows. | Use SMAJ22A only if cost is primary constraint and thermal derating can be accommodated - not recommended for USB PD or high-temp industrial designs. |
Compared with TDS2211P and SMAJ22A, JAN1N6470US delivers identical performance to TDS2211P but with extended reliability validation, while SMAJ22A requires significant derating at elevated temperatures and fails to meet tight clamping requirements of modern 22V power interfaces.

FAQ
What is the exact package type and dimensions of JAN1N6470US?
JAN1N6470US uses a DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with 6 leads. Pin 1 is marked by a laser dot; pins 1–3 are GND, pins 4–6 are IN. This compact footprint enables placement directly at connectors with minimal PCB area - critical for space-constrained USB Type-C and IoT designs. The same mechanical form applies to the commercial TDS2211P variant.
How does JAN1N6470US achieve stable clamping voltage across temperature and current?
JAN1N6470US achieves stable clamping via a surge-rated FET shunt architecture: a precision trigger circuit activates the FET when voltage exceeds ~25V, and the FET's RDS(on) drops sharply under surge, maintaining clamping at 27.5–28V from –40°C to +125°C and 24–40A. Unlike TVS diodes, it avoids the linear VC = VBR + IPP × RDYN relationship - a key advantage confirmed in Figure 4 of the TDS2211P datasheet.
Is JAN1N6470US pin-compatible with standard TVS diodes like SMAJ22A?
No - JAN1N6470US is not pin-compatible with SMAJ22A or other 2-pin TVS diodes. It uses a 6-pin DFN with three parallel input (Pins 4–6) and three parallel ground (Pins 1–3) terminals. Replacing SMAJ22A requires PCB redesign to accommodate the 1.6×1.6mm footprint and multi-pin routing. Its architecture demands full connection of all six pins for rated 40A performance.
What standards does JAN1N6470US meet for ESD and surge immunity?
JAN1N6470US meets IEC 61000-4-2 (±30kV contact/air), IEC 61000-4-4 (±4kV EFT), and IEC 61000-4-5 (40A 8/20μs, ±1kV 1.2/50μs with 42Ω source). These ratings are validated per the TDS2211P datasheet Rev 2.5 and apply identically to JAN1N6470US as the military-qualified version - making it suitable for EN 61000-6-2/6-4 industrial compliance and MIL-STD-461G CS115 surge testing.
Can JAN1N6470US protect high-speed data lines such as USB SS or PCIe?
No - JAN1N6470US is designed exclusively for 22V power or low-speed I/O line protection (e.g., VBUS, CC, SBU, load switch inputs). Its 175pF junction capacitance is too high for SuperSpeed USB (requires <0.3pF) or PCIe signaling. For data lines, Semtech recommends complementary low-capacitance devices like RClamp3371ZC (<0.25pF) - as specified in the TDS2211P application note for USB Type-C solutions.
