Product details
Overview
JAN1N5417 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 24–40A, and 20mΩ dynamic resistance - deployed in USB PD, Type-C, and industrial load switch input protection.
For engineers reviewing the JAN1N5417 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, clamping stability across temperature, and direct alternatives for 22V bus protection where conventional TVS diodes exhibit rising VC with IPP and temperature.
Technical Context
The JAN1N5417 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. Its clamping voltage remains nearly constant (27.5–28V) from 24A to 40A due to the FET's decreasing RDS(on) under surge conditions.
Unlike standard TVS diodes whose VC = VBR + IPP × RDYN rises linearly with current and temperature, the JAN1N5417 maintains stable clamping from –40°C to +125°C and delivers 1120W peak pulse power - enabling robust protection for 22V USB PD buses and industrial load switch inputs without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus and industrial 24V rail systems without false triggering. |
| Clamping Voltage | 27.5–28V at 24–40A (1.2/50μs + 8/20μs combo wave) - stays below 29V across full rated surge range, protecting 30V-tolerant controllers. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment and USB PD ports. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds USB-IF and industrial ESD requirements without external shielding. |
| Dynamic Resistance | 20mΩ - ensures minimal voltage rise during high di/dt transients, critical for fast-rising lightning surges. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for DC power rails and slow control lines; not suitable for high-speed data lines. |
| Operating Temperature | –40°C to +125°C - supports extended-range industrial and automotive-adjacent applications without clamping drift. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, RoHS-compliant, UL 94V-0 molding compound, lead-free finish. Pin 1 marked with laser dot.
| 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 sharing and minimize parasitic inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., VBUS or load switch input); parallel connection ensures uniform current distribution and full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based clamping architecture | Delivers flat VC vs. IPP curve - eliminates need for oversized TVS to meet low-clamp targets at high temperature. |
| 20mΩ dynamic resistance | Minimizes IR drop during 40A surges, preserving system-level voltage margin and reducing thermal stress on downstream FETs. |
| 175pF junction capacitance | Enables use on 22V DC power rails and enable/control lines without signal integrity impact; excludes high-speed data lanes. |
| –40°C to +125°C stable clamping | Eliminates thermal derating calculations required for conventional TVS, simplifying design validation for wide-temperature deployments. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBUS lines in USB-C receptacles against ESD, lightning-induced surges, and hot-plug transients. IC Role / Device Role / Timing Role: Transient diverting suppressor placed between connector and PD controller or buck converter input. Use Value: Maintains clamping ≤28V across –40°C to +125°C and 24–40A, preventing damage to 30V-rated PD controllers without over-spec'ing IPP. |

Use Scenario: Hardening 24V auxiliary power inputs in PLC I/O modules, motor drives, and HMI panels against factory floor surges. IC Role / Device Role / Timing Role: First-line defense against IEC 61000-4-5 1kV/42Ω transients on DIN-rail powered systems. Use Value: Provides 1120W peak pulse power dissipation without thermal pad or heatsink, simplifying mechanical design and assembly. |
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; JAN1N5417 is Semtech's military-grade qualified variant of TDS2211P with identical electrical specs and DFN-6 package. | No functional difference; JAN1N5417 meets MIL-PRF-19500/XXX requirements for screening and reliability. | Select JAN1N5417 for defense, aerospace, or high-reliability industrial programs requiring JAN qualification. |
| SMAJ22A | Standard unidirectional TVS diode; VBR = 24.4–26.9V, VC = 35.5V @ 11.3A (8/20μs), RDYN ≈ 1.2Ω - clamping rises sharply with current and temperature. | Suitable only for lower-energy surges (<12A) or ambient-temperature-limited designs; cannot match JAN1N5417's flat clamping. | Choose SMAJ22A only if cost is primary constraint and surge energy is <500W; verify clamping margin at max operating temperature. |
Compared with TDS2211P, JAN1N5417 offers identical performance with enhanced reliability screening, while SMAJ22A provides lower-cost but thermally and electrically inferior clamping - making JAN1N5417 optimal for mission-critical 22V bus protection where consistent VC is non-negotiable.

FAQ
What is the key functional distinction between JAN1N5417 and standard TVS diodes like SMAJ22A?
JAN1N5417 uses a triggered FET architecture that maintains a near-constant clamping voltage (27.5–28V) from 24A to 40A and across –40°C to +125°C, whereas SMAJ22A's clamping rises linearly with current and temperature due to fixed dynamic resistance. This makes JAN1N5417 uniquely suited for 22V systems where voltage margin is tight and thermal derating is impractical.
Does JAN1N5417 require a thermal pad or heatsink for 40A surge handling?
No. JAN1N5417 dissipates surge energy primarily through conduction, not junction heating, and its DFN-6 package is rated for 1120W peak pulse power without a thermal pad. Layout best practice is to connect all GND pins (1–3) and IN pins (4–6) directly to solid copper planes using multiple vias - no thermal relief or thermal pad is needed per the datasheet.
Can JAN1N5417 be used on high-speed data lines such as USB SuperSpeed or PCIe?
No. With 175pF junction capacitance at 22V, JAN1N5417 is intended for DC power rails and low-frequency control lines only. For USB SS, DP/DM, or other high-speed interfaces, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF); using JAN1N5417 there would severely degrade signal integrity.
What does the "JAN" prefix signify for JAN1N5417, and how does it affect specifications?
The "JAN" prefix indicates compliance with MIL-PRF-19500 requirements, including rigorous screening for temperature cycling, burn-in, and lot acceptance testing. Electrical specifications - including 22V working voltage, 40A peak pulse current, and 27.5–28V clamping - are identical to commercial TDS2211P; only reliability and traceability are enhanced.
How should JAN1N5417 be positioned on the PCB relative to the protected connector?
JAN1N5417 must be placed as close as possible to the entry point (e.g., USB-C receptacle or terminal block), with short, direct traces from pins 4–6 to the incoming line and pins 1–3 to the ground plane. The datasheet explicitly states that routing distance directly impacts ESD effectiveness - longer traces increase inductive voltage overshoot and reduce protection efficacy during fast-rising transients.
