Product details
Overview
JAN1N5418 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, USB Type-C, and industrial load switch input protection.
For engineers reviewing the JAN1N5418 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, temperature-stable clamping behavior, and real-world implementation context for surge-protected bus design.
Technical Context
The JAN1N5418 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 conventional TVS diodes, its clamping voltage remains nearly constant across 24–40A peak pulse currents due to decreasing RDS(on) under surge conditions.
It operates from −40°C to +125°C with stable 27.5–28V clamping at 40A (1.2/50μs + 8/20μs combination waveform, RS = 2Ω), 22V reverse stand-off voltage, and 175pF junction capacitance at 22V/1MHz - enabling robust protection without signal integrity compromise in high-speed interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-Off Voltage | 22 V - defines maximum continuous operating voltage before activation; matches USB PD 20V nominal + margin. |
| Clamping Voltage (40A) | 27.5–28 V - limits transient voltage seen by downstream ICs (e.g., USB PD controllers) during 40A surges. |
| Peak Pulse Current | 40 A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds standard human-body model requirements for rugged front-end protection. |
| Dynamic Resistance | 20 mΩ - enables low-voltage drop during high-current transients, minimizing energy dissipation in protected circuitry. |
| Junction Capacitance | 175 pF @ 22V, 1MHz - compatible with DC-biased power rails and low-speed control lines; not suitable for >100MHz data paths. |
Pinout & Package
Package: DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead, Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three pins must be connected to maximize current handling and minimize parasitic inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., VBUS, load switch input); all three pins are internally tied and must be shorted externally for full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage vs. IPP | 27.5–28 V across 24–40A range - eliminates need for oversized TVS to meet clamping targets at high temperature. |
| Temperature-stable clamping | Clamping remains flat from −40°C to +125°C - ensures consistent protection in automotive and industrial environments. |
| Low dynamic resistance | 20 mΩ - reduces voltage overshoot and thermal stress on protected FETs in load switches and e-fuses. |
| High-energy surge capability | 1120 W peak pulse power (8/20μs) - supports repeated lightning-surge events per IEC 61000-4-5. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting 20V USB PD bus against ESD and surge events near the Type-C connector. IC Role / Device Role / Timing Role: Transient diverting suppressor placed between VBUS and GND to clamp overvoltage before reaching PD controller. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents damage to PD controllers rated ≤30V absolute max. |
Use Scenario: Safeguarding HS2950P or similar load switches in remote meters and robotics against lightning-induced surges. IC Role / Device Role / Timing Role: Front-end EOS protector on VIN rail, limiting voltage seen by internal switch FET. Use Value: Keeps clamping below 30V across temperature - avoids gate oxide breakdown and ensures reliable OVP/UVLO operation. |

|
Use Scenario: Securing 22V-rated power inputs in battery-powered IoT gateways exposed to field ESD. IC Role / Device Role / Timing Role: Primary surge diverter on main DC input, coordinated with secondary low-capacitance TVS on signal lines. Use Value: Delivers ±30kV ESD immunity and 40A surge handling in 1.6×1.6mm footprint - saves board space vs. discrete TVS+MOV solutions. |
Use Scenario: Protecting notebook VBUS lines during hot-plug events and accidental shorts in docking stations. IC Role / Device Role / Timing Role: Solid-state shunt protector replacing traditional Zener-based clamps for tighter voltage control. Use Value: 22V working voltage and 27.5V clamping enable compatibility with 20V PD profiles while avoiding false triggering during normal operation. |
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, identical electrical specs, DFN-6 package, marked T22; JAN1N5418 is military-grade screened variant of TDS2211P.C. | Qualified to MIL-PRF-19500/560; specified for extended temperature and reliability testing beyond commercial grade. | Select JAN1N5418 for defense, aerospace, or high-reliability industrial programs requiring JAN screening. |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, 0.25pF capacitance - optimized for CC/SBU lines, not power rails. | Designed for low-capacitance data-line protection; lacks the power-handling capability and thermal stability of JAN1N5418. | Use uClamp2411ZA only on auxiliary signal lines; JAN1N5418 remains preferred for VBUS and load-switch input protection. |
Compared with TDS2211P.C, JAN1N5418 offers identical surge performance with enhanced reliability screening, while uClamp2411ZA serves complementary low-capacitance roles but cannot replace JAN1N5418 in high-current power-rail applications.

FAQ
What is the key functional difference between JAN1N5418 and standard TVS diodes?
JAN1N5418 uses a surge-rated FET with precision trigger circuitry instead of a pn-junction, delivering near-constant 27.5–28V clamping across 24–40A and −40°C to +125°C. Standard TVS diodes exhibit rising clamping voltage with both current and temperature - a limitation JAN1N5418 eliminates for robust power-rail protection.
Does JAN1N5418 require external bias or control signals to operate?
No. JAN1N5418 is fully passive and self-activating: it remains high-impedance below 22V reverse stand-off voltage and automatically triggers the internal shunt FET when overvoltage is detected. No external power, enable pins, or configuration are needed - simplifying integration into VBUS or load switch input paths.
Can JAN1N5418 be used on high-speed data lines like USB SuperSpeed or PCIe?
No. With 175pF junction capacitance at 22V, JAN1N5418 is intended for DC or low-frequency power and control lines - not high-speed differential pairs. For USB SS, DP/DM, or PCIe lanes, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF), while JAN1N5418 protects the associated VBUS or power rails.
What is the significance of the "JAN" prefix in JAN1N5418?
The "JAN" prefix indicates Joint Army-Navy qualification per MIL-PRF-19500/560, confirming JAN1N5418 has undergone extended environmental stress testing (e.g., temperature cycling, burn-in, hermeticity) beyond commercial-grade TDS2211P.C. This makes JAN1N5418 suitable for defense, avionics, and mission-critical industrial applications.
How should PCB layout be optimized for maximum surge performance with JAN1N5418?
Place JAN1N5418 within 5 mm of the protected connector. Connect all three IN pins (4,5,6) with a single low-inductance trace to the protected line, and tie all three GND pins (1,2,3) directly to a solid ground plane using ≥4 vias. Avoid stubs or splits - this minimizes impedance and ensures full 40A surge current sharing across parallel paths.
