Product details
Overview
JANTXV1N5802US 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 Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the JANTXV1N5802US datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance for minimal voltage overshoot, DFN-6 package layout constraints, and compatibility with 22V bus systems requiring robust surge immunity per IEC 61000-4-5.
Technical Context
The JANTXV1N5802US implements a precision-triggered shunt FET architecture: a dedicated trigger circuit senses overvoltage events and activates a low-RDS(on) MOSFET to divert transients to ground. Unlike conventional TVS diodes, its clamping voltage remains nearly constant (27.5–28V) from 24A to 40A due to decreasing FET on-resistance under surge conditions.
It 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 1120W peak pulse power rating support high-speed data line integration while maintaining robust energy handling.
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 conduction. |
| 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. |
| Dynamic Resistance | 20mΩ - enables flat clamping response; limits voltage rise to ≤0.8V per 40A increase, critical for tight voltage margin designs. |
| Junction Capacitance | 175pF at 22V/1MHz - compatible with USB Type-C VBUS protection where signal integrity on adjacent high-speed lanes is preserved. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Level 4 ESD immunity for handheld and industrial interfaces. |
| Operating Temp | –40°C to +125°C - supports deployment in automotive cabin, industrial control, and outdoor IoT enclosures without derating. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, RoHS-compliant, UL 94V-0 molding compound, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three pins must be connected to minimize inductance and maximize 40A capability. |
| 4, 5, 6 | IN | Protected line input (e.g., VBUS); parallel connection of all three pins ensures uniform current sharing and thermal distribution during 40A transients. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A - eliminates need for over-spec'ing IPP to meet voltage margin, reducing BOM cost and board space. |
| FET-based shunt topology | 20mΩ dynamic resistance enables sub-1V voltage rise per 50A - superior to TVS diodes whose VC rises linearly with IPP × RDYN. |
| Temperature-stable clamping | Clamps at 27.5–28V from –40°C to +125°C - removes thermal derating uncertainty in industrial and automotive ambient environments. |
| Low-leakage protection | ≤600nA reverse leakage at 22V - prevents battery drain in always-on IoT and metering applications with long standby life requirements. |
| Compact DFN footprint | 1.6mm × 1.6mm area - saves >60% board space vs. SO-8 or SOT-23 TVS solutions rated for equivalent 40A surge performance. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Front-End Protection |
|---|---|
|
Use Scenario: Protecting 20–22V VBUS lines in USB-C PD ports against lightning-induced surges and connector hot-plug ESD. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed directly at connector, clamping transients before they reach PD controller and buck-boost ICs. Use Value: Maintains 27.5V clamping at full 40A surge and 125°C - prevents latch-up or gate oxide damage in 24V-tolerant PD controllers without thermal derating. |

IC Role / Device Role / Timing Role: High-current transient diverter that limits voltage across load switch FET's drain-source during 1kV/42Ω surges. Use Value: Keeps clamping voltage below 28V across –40°C to +125°C - avoids internal FET avalanche failure and ensures reliable OVP/UVLO operation during repeated surges. |
| IoT Edge Device Power Bus Protection | Storage Device 12–24V Rail Protection |
|
Use Scenario: Securing 22V auxiliary power inputs in battery-backed smart sensors and gateway devices exposed to EFT and ESD in factory environments. IC Role / Device Role / Timing Role: Low-capacitance, low-leakage EOS suppressor enabling multi-year battery life while meeting IEC 61000-4-4 ±4kV EFT immunity. Use Value: 175pF capacitance minimizes signal distortion on shared power/data rails; 600nA max leakage preserves >10-year shelf life in sealed enclosures. |
Use Scenario: Hardening 12V/24V power inputs of NVMe SSD enclosures and enterprise HDD backplanes against system-level surges and hot-swap transients. IC Role / Device Role / Timing Role: High-energy transient clamp on primary power rail, coordinated with low-capacitance TVS on data lanes (e.g., RClamp3371ZC). Use Value: 1120W peak pulse power rating handles multiple 40A surges without degradation - extends field reliability beyond 100,000 insertion cycles in datacenter infrastructure. |
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.C | Identical electrical specs, same DFN-6 package, commercial-grade (–40°C to +125°C), non-military marking. | Approved for commercial USB-C, IoT, and storage applications; lacks MIL-PRF-19500 screening and JANTXV suffix. | Select JANTXV1N5802US when MIL-STD-883 Class V screening, extended reliability testing, or defense/aerospace qualification is required. |
| Littelfuse SP3022-01WTG | TVS diode (not FET-based); 24V VRWM, 35.5V VC @ 20A, higher clamping, no current-flatness, 22pF capacitance. | Lower-cost alternative for less demanding 22V systems where 35.5V clamping is acceptable and temperature stability is secondary. | Choose only if design tolerates ≥7.5V higher clamping and does not require stable VC across temperature or current range. |
Compared with TDS2211P.C and SP3022-01WTG, JANTXV1N5802US delivers military-grade reliability with identical clamping performance, while SP3022-01WTG trades clamping accuracy and thermal stability for lower unit cost in non-critical commercial deployments.

FAQ
What is the exact package type and dimensions of JANTXV1N5802US?
JANTXV1N5802US uses a DFN package measuring 1.6mm × 1.6mm × 0.55mm with six leads. Pins 1–3 are ground terminals and pins 4–6 are input terminals. The package is Pb-free, halogen-free, RoHS/WEEE compliant, and carries UL 94V-0 flammability rating. This compact footprint enables high-density PCB layouts in space-constrained USB-C and industrial modules.
How does JANTXV1N5802US achieve constant clamping voltage across varying surge currents?
JANTXV1N5802US achieves constant clamping via a precision-triggered shunt FET architecture. When an overvoltage event occurs, the internal trigger circuit activates a low-RDS(on) MOSFET, whose on-resistance decreases as surge current increases - counteracting the typical VC = VBR + IPP × RDYN rise seen in TVS diodes. As a result, JANTXV1N5802US maintains 27.5–28V clamping from 24A to 40A.
Is JANTXV1N5802US suitable for protecting USB Type-C VBUS lines operating up to 20V?
Yes - JANTXV1N5802US has a 22V reverse stand-off voltage and clamps at 27.5–28V under full 40A surge, making it ideal for USB Type-C PD applications where VBUS reaches 20V nominal and must withstand 22V transients. Its 175pF capacitance avoids interference with SuperSpeed data lanes when placed on VBUS only, as confirmed in Semtech's reference design.
What is the maximum operating temperature range for JANTXV1N5802US?
JANTXV1N5802US is rated for continuous operation from –40°C to +125°C. Its clamping voltage remains stable across this full range - unlike standard TVS diodes, which exhibit rising VC with temperature. This makes JANTXV1N5802US suitable for under-hood automotive, industrial control cabinets, and outdoor IoT deployments where ambient extremes are expected.
Does JANTXV1N5802US require a thermal pad or heatsink for 40A surge handling?
No - JANTXV1N5802US dissipates surge energy through its internal FET structure without requiring an exposed thermal pad. Semtech's datasheet explicitly states "no thermal pad is needed" and recommends connecting all GND pins (1–3) and IN pins (4–6) directly to solid copper planes using multiple vias to minimize parasitic inductance. Thermal management relies on PCB copper mass, not external heatsinking.
