Product details
Overview
JANTX1N3613 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, 20mΩ dynamic resistance, and 175pF junction capacitance - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the JANTX1N3613 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance for flat VC vs. IPP behavior, DFN-6 package layout constraints, and compatibility with 22V bus systems requiring robust ±1kV surge (IEC 61000-4-5) and ±4kV EFT (IEC 61000-4-4) immunity.
Technical Context
JANTX1N3613 implements a surge-rated FET-based shunt architecture with a precision trigger circuit that activates the low-RDS(on) FET during overvoltage events, enabling near-constant clamping voltage independent of peak pulse current magnitude. Unlike conventional TVS diodes, its clamping voltage remains stable from −40°C to +125°C due to active switching rather than passive junction conduction.
The device operates as a bidirectional, single-line protector 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. Its solid-state design eliminates thermal runaway risks associated with silicon avalanche diodes under repeated transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage degradation. |
| Clamping Voltage | 27.5–28V at 24–40A (1.2/50μs + 8/20μs combo wave, RS = 2Ω) - ensures downstream 22V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| Peak Pulse Current | 40A (8/20μs) - supports compliance with IEC 61000-4-5 Level 4 (±1kV, RS = 42Ω) on unsymmetrical lines. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds industrial and consumer interface ESD requirements without derating. |
| Dynamic Resistance | 20mΩ (measured 1–40A, 8/20μs) - enables flat clamping curve and minimizes voltage overshoot during fast-rising transients. |
| Junction Capacitance | 175pF @ 22V, 1MHz - suitable for <22V power rail and low-speed signal line protection; not intended for >100MHz data paths. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Low-inductance ground return path; all three must be connected to PCB ground plane via multiple vias for full 40A surge capability. |
| Pins 4, 5, 6 | IN | Parallel-connected input terminals for protected bus; all three required to distribute surge current and minimize trace inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage across IPP and temperature | VC varies ≤0.5V from −40°C to +125°C and 1A–40A - eliminates need for derating at high ambient or high-current conditions. |
| Surge-rated FET shunt architecture | Replaces avalanche junction with actively triggered MOSFET - avoids thermal runaway and enables repeatable surge endurance. |
| Low dynamic resistance | 20mΩ enables <1V overshoot during 10A/μs dI/dt transients - critical for protecting sensitive load switches and e-fuses. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz bursts) - protects against repetitive switching noise in industrial motor drives and PLCs. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Front-End Protection |
|---|---|
Use Scenario: Protecting VBus lines in USB-C receptacles supporting up to 20V/5A PD negotiation, exposed to ESD from hot-plug and lightning-induced surges on attached cables. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed between connector and USB PD controller or load switch input, activated within nanoseconds of overvoltage detection. Use Value: Maintains 27.5–28V clamping across full temperature range and 40A surge, preventing latch-up or gate oxide damage in 22V-tolerant PD controllers like TUSB73x or CYPD3177. |

Use Value: 130–600nA reverse leakage at 22V ensures minimal standby power loss - critical for multi-year battery life in LPWAN nodes. |
Use Scenario: Protecting 22V backup supplies in enterprise SSDs and NAS enclosures where sudden voltage spikes from shared PSUs or hot-swap events threaten NAND controller integrity. IC Role / Device Role / Timing Role: Standby-mode protector on VCC rail feeding PMICs and flash memory controllers, activated only during transients. Use Value: 1120W peak pulse power rating (8/20μs) absorbs energy from capacitor discharge events without degradation over >1000 surges. |
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 | Same die, identical electrical specs and package; JANTX1N3613 is the MIL-PRF-19500/566 qualified version with extended screening and traceability. | Qualified for military/aerospace use per JANTX level; includes lot traceability, burn-in, and radiation hardness testing not present in commercial TDS2211P. | Select JANTX1N3613 when DO-160, MIL-STD-461, or MIL-PRF-19500 compliance is mandatory; otherwise TDS2211P suffices for commercial industrial designs. |
| Littelfuse SP3022-01WTG | TVS diode (not FET-based); 22V VRWM, 33.6V VC @ 24A, higher clamping (+6V), no temperature stability - clamping rises with temperature and current. | Lower cost, smaller footprint (0201), but cannot match JANTX1N3613's flat clamping or 40A rating; limited to ≤12A surges in practice. | Use SP3022-01WTG only for space-constrained, cost-sensitive, low-energy (<12A) applications where ±1kV surge margin is acceptable. |
Compared with TDS2211P, JANTX1N3613 adds military-grade reliability screening without altering electrical performance; versus SP3022-01WTG, it delivers 6V lower clamping, 3.3× higher surge rating, and stable voltage control across temperature - essential for protecting 22V-tolerant PD controllers and load switches in harsh environments.

FAQ
What is the primary function of JANTX1N3613 in a circuit?
JANTX1N3613 functions as a transient diverting suppressor that actively shunts high-energy EOS events-such as ESD, lightning surges, and EFT-to ground using a precision-triggered FET. It maintains a stable 27.5–28V clamping voltage across 1–40A surge currents and −40°C to +125°C, protecting 22V-rated components like USB PD controllers and load switches. The JANTX1N3613 achieves this through low 20mΩ dynamic resistance and eliminates the voltage rise typical of standard TVS diodes.
How does JANTX1N3613 differ from standard TVS diodes like SMAJ22A?
JANTX1N3613 uses a surge-rated FET with a precision trigger circuit instead of a passive PN-junction, resulting in near-constant clamping voltage (27.5–28V) across its full 40A rating and temperature range. In contrast, SMAJ22A exhibits rising clamping (e.g., ~38V at 24A/125°C) due to fixed dynamic resistance. JANTX1N3613 also offers ±30kV ESD, ±4kV EFT, and 1120W peak power-capabilities beyond most unidirectional TVS diodes. The JANTX1N3613 is thus suited for mission-critical 22V rail protection where voltage margin is tight.
What are the PCB layout requirements for optimal performance of JANTX1N3613?
For optimal JANTX1N3613 performance, all three IN pins (4–6) must connect via a single short, wide trace to the protected line, and all three GND pins (1–3) must connect to a solid ground plane using ≥3 vias each. The device must be placed within 5mm of the connector or surge entry point to minimize parasitic inductance. Avoid thermal pads or isolated copper islands under the package - energy is dissipated internally, and grounding vias provide the sole thermal path. This layout ensures full 40A surge handling and preserves the JANTX1N3613's low-inductance shunt path.
Is JANTX1N3613 compatible with automated SMT assembly processes?
Yes, JANTX1N3613 is fully compatible with standard SMT reflow processes. Its DFN-6 package (1.6mm × 1.6mm × 0.55mm) meets IPC-7351B footprint standards, and the lead-free, halogen-free construction supports Pb-free solder profiles (peak temp ≤260°C). The device has been qualified per MIL-PRF-19500/566 for mechanical shock, vibration, and thermal cycling - confirming robustness during board assembly and field operation. JANTX1N3613's marking ("T22" + date code) is laser-etched for post-reflow readability.
Does JANTX1N3613 require external biasing or control signals to operate?
No, JANTX1N3613 is a fully autonomous, passive-acting protector requiring no external power, biasing, or control signals. Its internal trigger circuit senses overvoltage across the IN-to-GND path and activates the shunt FET within nanoseconds. Once the transient subsides, the device automatically resets to high-impedance standby mode with only 130–600nA leakage at 22V. This self-contained operation makes JANTX1N3613 ideal for always-on protection in battery-powered or safety-critical systems where reliability cannot depend on auxiliary circuitry.
