Product details
Overview
JANTX1N6165 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 ultra-low 20mΩ dynamic resistance - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the JANTX1N6165 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DFN-6 package layout guidance, real-world clamping stability across temperature and current, and direct alternative options for 22V bus protection with constant-voltage surge suppression.
Technical Context
JANTX1N6165 uses 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 (27.5–28V) from 24A to 40A due to decreasing RDS(on) under surge conditions.
The device operates across –40°C to +125°C with stable 22V reverse stand-off voltage and <600nA leakage at VRWM; its 175pF junction capacitance at 22V/1MHz and 20mΩ dynamic resistance enable low-loss, high-fidelity protection without signal distortion in DC-biased power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or degradation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD robustness standards without derating. |
| Dynamic Resistance | 20mΩ - enables minimal voltage rise under high di/dt transients, critical for protecting low-tolerance FET-based load switches. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for DC power rail protection without affecting load switch response or feedback loop stability. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, RoHS-compliant, UL 94V-0 molding compound, lead-free finish, tape-and-reel packaging (3,000 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return 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 in USB PD); all three pins are internally paralleled and must be shorted externally for full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A - eliminates need for over-specifying IPP to meet voltage margin, simplifying selection. |
| Temperature-stable clamping | 27.5–28V clamping maintained from –40°C to +125°C - removes thermal derating calculations required for standard TVS diodes. |
| Low dynamic resistance | 20mΩ enables sub-1V IR drop at 40A - preserves voltage headroom for 22V systems with tight regulation margins. |
| High-energy ESD immunity | ±30kV contact/air per IEC 61000-4-2 - protects against human-body-model events without external shielding or layout constraints. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Front-End Protection |
|---|---|
Use Scenario: Protecting VBUS line in USB-C receptacles supporting up to 20V/5A PD negotiation, exposed to lightning-induced surges and hot-plug ESD. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed between connector and upstream load switch or PD controller. Use Value: Maintains 27.5V clamping at 40A and 125°C - prevents latch-up or gate oxide damage in 24V-rated PD controllers where standard TVS would exceed 35V. |
Use Scenario: Safeguarding input of programmable load switches (e.g., HS2950P) in remote meters, robotics, and IoT edge nodes subject to 1kV/42Ω surges. IC Role / Device Role / Timing Role: First-line transient diverter before the load switch's internal FET, limiting drain-source voltage during surge. Use Value: 20mΩ RDYN limits voltage overshoot to <1V above clamping level - avoids exceeding the 30V absolute max rating of typical integrated load switch FETs. |
| 22V Industrial Power Rail Protection | High-Voltage IoT Sensor Bus Protection |
Use Scenario: Securing 22V auxiliary power rails in PLC I/O modules and motor drive control boards against field-wiring transients. IC Role / Device Role / Timing Role: Standalone transient suppressor on DC input stage, replacing multi-stage TVS+MOV solutions. Use Value: 1120W peak pulse power rating supports single-device compliance with IEC 61000-4-5 Level 4 - reduces BOM count and PCB area vs. discrete alternatives. |
Use Scenario: Protecting analog sensor supply lines (e.g., 22V bias for industrial pressure transducers) in battery-powered wireless nodes. IC Role / Device Role / Timing Role: Low-leakage (≤600nA) shunt protector preserving microamp-level sleep current integrity. Use Value: 130–600nA reverse leakage at 22V ensures <1μA total added system quiescent current - critical for 10-year battery life in LPWAN sensors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | Standard unidirectional TVS diode; 35.1V min clamping at 12.3A (8/20μs); no constant-clamp behavior; 1.5× higher clamping voltage at rated current. | Requires higher IPP rating to achieve comparable clamping; unsuitable for 24V ICs with narrow voltage margins. | Select only if cost sensitivity outweighs clamping precision and thermal stability requirements. |
| TPD2E007DRYR | Low-capacitance (3.5pF) dual-channel TVS; 24V working voltage; 1A peak pulse rating; not rated for 40A surges or industrial IEC 61000-4-5. | Limited to data-line ESD protection (e.g., USB D+/D−); cannot replace JANTX1N6165 on power rails. | Use exclusively for signal-line protection; never as a power-rail substitute for JANTX1N6165. |
Compared with SMAJ22A and TPD2E007DRYR, JANTX1N6165 uniquely delivers 27.5V clamping at 40A with <0.5V variation across temperature and current - enabling robust 22V system protection without overdesign, while the alternatives either overclamp or lack surge energy handling capability.

FAQ
What is the exact clamping voltage of JANTX1N6165 at 40A surge current?
JANTX1N6165 clamps at 27.5–28V under IEC 61000-4-5 combination waveform (1.2/50μs voltage + 8/20μs current, RS = 2Ω) at 40A peak pulse current. This value is guaranteed across –40°C to +125°C and reflects the device's constant-clamp architecture enabled by its surge-rated FET topology - a key differentiator from standard TVS diodes whose clamping rises linearly with current.
Does JANTX1N6165 require external bias or control signals to operate?
No, JANTX1N6165 is fully autonomous and requires no external bias, enable signals, or configuration. It operates passively: the internal trigger circuit activates the shunt FET only when transient voltage exceeds its breakdown threshold (~25–27.9V), then returns to high-impedance standby mode after event clearance. This makes JANTX1N6165 drop-in compatible with existing PCB layouts designed for 2-pin TVS devices, despite its 6-pin DFN package.
Can JANTX1N6165 be used on AC-coupled signal lines like USB SuperSpeed differential pairs?
No, JANTX1N6165 is not suitable for AC-coupled high-speed data lines. Its 175pF junction capacitance at 22V would severely degrade signal integrity on >5Gbps links. For USB SuperSpeed (TX/RX), Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF). JANTX1N6165 is specifically intended for DC-biased power rails and low-frequency I/O lines where capacitance is non-critical.
How does JANTX1N6165's thermal performance compare to standard TVS diodes at 125°C ambient?
At 125°C, JANTX1N6165 maintains 27.5–28V clamping voltage across its full 40A rating, whereas standard TVS diodes (e.g., SMAJ22A) exhibit ≥35V clamping at same current due to positive temperature coefficient of dynamic resistance. This stability eliminates thermal derating and ensures consistent protection margin for 24V-rated ICs in enclosed industrial enclosures - a documented advantage confirmed in Semtech's Figure 3 clamping comparison.
Is JANTX1N6165 pin-compatible with any industry-standard TVS packages?
JANTX1N6165 uses a proprietary 6-pin DFN (1.6mm × 1.6mm) with three parallel input pins (4–6) and three parallel ground pins (1–3); it has no direct pin-to-pin replacement among standard DO-214AC (SMA), SOD-123, or SOT-23 TVS packages. Layout adaptation is required: all six pins must be routed - GND pins to solid ground plane via multiple vias, IN pins shorted together near the connector - to achieve rated 40A performance.
