Product details
Overview
JANTX1N3614 from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection on 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 - deployed in USB Type-C PD input protection and industrial load switch front-end surge suppression.
For engineers reviewing the JANTX1N3614 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specifications, DFN-6 package layout guidance, real-world clamping stability across temperature and current, and direct alternative options for 22V bus protection with constant-voltage shunt behavior.
Technical Context
JANTX1N3614 implements a precision-triggered, surge-rated FET as its primary protection element - unlike conventional TVS diodes - enabling near-constant clamping voltage over 24–40A peak pulse current and −40°C to +125°C operating temperature. Its trigger circuit activates the shunt FET when transient voltage exceeds breakdown, bypassing energy to ground via sub-0.1Ω RDS(on).
The device 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 rating. It exhibits 175pF junction capacitance at 22V and <600nA reverse leakage, making it suitable for DC-bus protection where low capacitance is secondary to robust clamping stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage before leakage or triggering onset. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures protected ICs (e.g., USB PD controllers) remain below damage threshold under worst-case surge. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds standard system-level ESD test requirements without degradation. |
| Dynamic Resistance | 20mΩ - enables flat clamping curve; clamping voltage rise ≤0.5V from 1A to 40A. |
| Junction Capacitance | 175pF at 22V, 1MHz - compatible with 20V DC power rails; not intended for high-speed data line protection. |
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; thermal dissipation occurs through copper traces and vias to internal ground planes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Low-inductance ground return path; all three must be connected to maximize surge current handling and minimize voltage overshoot. |
| Pins 4, 5, 6 | IN | Parallel-connected input terminals for protected bus; equal current sharing ensures full 40A rating and balanced thermal distribution. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V across full 1–40A surge range - eliminates design margin inflation needed with conventional TVS. |
| Temperature-stable protection | Clamping remains 27.5–28V from −40°C to +125°C - removes derating calculations for industrial ambient conditions. |
| High-energy surge capability | 1120W peak pulse power (8/20μs) - supports repeated lightning-surge events without parametric shift or failure. |
| Low-leakage standby | ≤600nA at 22V - avoids battery drain or bias errors in always-on industrial monitoring circuits. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Front-End Protection |
|---|---|
Use Scenario: Protecting VCONN/VBUS lines in USB-C receptacles supporting up to 20V/5A PD negotiation. IC Role / Device Role / Timing Role: Shunt-based transient diverter placed between connector and PD controller or e-fuse IC. Use Value: Maintains 27.5V clamping at 40A and 125°C - prevents overvoltage latch-up in TI TPS6598x or STUSB4500 controllers during surge events. |

Use Scenario: Protecting supercapacitor-charged 22V backup supplies in NVMe SSDs and enterprise HDD controllers. IC Role / Device Role / Timing Role: Clamping element on backup power path to prevent overvoltage damage to charge management ICs. Use Value: 20mΩ dynamic resistance minimizes voltage drop during normal operation while ensuring fast, low-overshoot clamping during capacitor discharge transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Semtech TDS2211P | Identical die, same DFN-6 package, identical electrical specs - JANTX1N3614 is the MIL-PRF-19500/566 qualified version with extended screening. | Qualified for military/aerospace use per JANTX level; includes lot traceability, burn-in, and radiation hardness testing. | Select JANTX1N3614 for defense, avionics, or space-qualified systems requiring MIL-spec reliability; TDS2211P suffices for commercial industrial designs. |
| Littelfuse SP3022-01FTG | Unidirectional TVS diode; 24V working voltage; 30A (8/20μs); clamping rises to ~42V at 30A; no active trigger circuit. | Lacks constant-clamp behavior; requires larger voltage margin for same surge rating; higher temperature drift. | Use only where cost sensitivity outweighs clamping precision; unsuitable for 22V systems with tight controller VDS(max) margins. |
Compared with TDS2211P, JANTX1N3614 adds military-grade screening without altering electrical performance; versus SP3022-01FTG, JANTX1N3614 provides 14V lower clamping at rated current and stable performance across temperature - critical for protecting 22V-rated silicon with narrow overvoltage tolerance.

FAQ
What is the key functional difference between JANTX1N3614 and standard TVS diodes?
JANTX1N3614 uses an actively triggered FET-based shunt architecture instead of a passive PN-junction. This yields near-constant 27.5–28V clamping from 1A to 40A and −40°C to +125°C - unlike TVS diodes whose clamping voltage rises linearly with current and temperature due to fixed dynamic resistance. The result is tighter voltage margin control for sensitive 22V-rated ICs.
Does JANTX1N3614 require external bias or control signals to operate?
No. JANTX1N3614 is fully autonomous: its internal precision trigger circuit detects overvoltage events above ~25V breakdown and automatically activates the shunt FET without any external power, enable pin, or configuration. It functions as a 2-terminal device - simply connect Pins 4–6 to the protected line and Pins 1–3 to ground.
Can JANTX1N3614 be used on high-speed data lines like USB SuperSpeed or PCIe?
No. With 175pF junction capacitance at 22V, JANTX1N3614 is intended exclusively for DC or low-frequency power and control lines. For USB SS, DP/DM, or PCIe lanes, Semtech recommends low-capacitance TVS devices such as RClamp3371ZC (<0.25pF). JANTX1N3614's role is strictly power-rail and robust I/O protection.
What is the significance of the "JANTX" prefix in JANTX1N3614?
The "JANTX" prefix indicates compliance with MIL-PRF-19500/566 - a U.S. military specification covering screening, testing, and quality assurance for discrete semiconductors. JANTX1N3614 undergoes additional tests including burn-in, thermal shock, and lot traceability beyond commercial-grade TDS2211P, making it suitable for aerospace, defense, and high-integrity industrial systems.
How should PCB layout be optimized for JANTX1N3614 to achieve full 40A surge rating?
To achieve rated 40A performance, connect all three IN pins (4–6) via a single low-inductance trace to the protected line, and tie all three GND pins (1–3) directly to a solid ground plane using ≥3 thermal vias per pin. Place JANTX1N3614 within 5mm of the connector entry point to minimize parasitic inductance - layout deviations reduce effective surge current handling and increase clamping overshoot.
