Product details
Overview
JANTX1N6464US.TR 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 PD input protection and industrial load switch front-end circuits.
For engineers reviewing the JANTX1N6464US.TR datasheet, pinout, applications, or equivalent options, this device offers stable clamping across temperature and current range - critical for USB Type-C VBUS, IoT power rail, and industrial e-fuse interface protection where conventional TVS diodes exhibit rising VC with IPP and temperature.
Technical Context
The JANTX1N6464US.TR uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events and drives the shunt FET into low-RDS(on) conduction. Its clamping voltage remains nearly constant (27.5–28V) from 24A to 40A due to decreasing FET on-resistance under surge conditions.
Unlike standard TVS diodes governed by VC = VBR + IPP × RDYN, the JANTX1N6464US.TR achieves flat clamping via active switching - delivering 20mΩ dynamic resistance and maintaining 27.5–28V clamping from –40°C to +125°C without thermal derating of IPP capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus and industrial 24V rail systems without derating. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave) - stays below 28V across full rated current and temperature range. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD requirements without external shielding. |
| Dynamic Resistance | 20mΩ - enables low-voltage overshoot during fast transients, reducing stress on downstream FETs and controllers. |
| Junction Capacitance | 175pF at 22V - suitable for DC power rails and low-speed control lines; not intended for high-speed data lines. |
| Reverse Leakage | 130–600nA at 22V - negligible power loss in always-on 22V supply monitoring applications. |
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 |

| Active FET-based suppression | Surge-rated shunt FET + precision trigger circuit replaces passive junction breakdown - delivers lower and more predictable VC than TVS diodes. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) - supports repeated lightning-surge events in remote meters and robotics without degradation. |
| Low dynamic resistance | 20mΩ measured between 1A–40A - minimizes voltage overshoot during sub-microsecond transients, protecting sensitive load switches. |
| Compact footprint | 1.6mm × 1.6mm DFN - saves >60% board area vs. SOT-23 or SMA TVS solutions while enabling higher surge ratings. |
Applications
| USB PD Input Protection | Industrial Load Switch Front-End |
|---|---|
Use Scenario: Protecting USB Type-C VBUS lines operating up to 20V nominal with 22V maximum tolerance against ESD and surge events. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed directly at connector, clamping transients before they reach PD controller or buck converter. Use Value: Maintains 27.5–28V clamping at full 40A surge and 125°C ambient - avoids overvoltage damage to USB PD ICs that fail above 28V. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) exposed to lightning-induced surges in remote metering or factory automation. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage seen by internal FET gate oxide and overvoltage protection circuitry. Use Value: Prevents latch-up or permanent damage to load switch ICs by holding clamping voltage below their absolute maximum VIN rating (typically 30–36V). |
| IoT Power Rail Protection | Robotics Power Distribution Unit |
Use Scenario: Securing 22V auxiliary power rails in battery-powered IoT gateways subjected to ESD during field servicing or connector mating. IC Role / Device Role / Timing Role: Single-component, low-leakage (≤600nA) protector for always-on power domains requiring long battery life and high reliability. Use Value: Delivers ±30kV ESD immunity without adding leakage current that would compromise multi-year battery operation. |
Use Scenario: Protecting main 24V distribution inputs in mobile robotic platforms where motor commutation and EMI induce repetitive fast transients. IC Role / Device Role / Timing Role: High-repetition-rate transient suppressor with stable clamping and no thermal runaway - sustains protection across continuous operation. Use Value: Enables >10,000 surge cycles at 24A without parameter shift, unlike TVS diodes that degrade after repeated surges. |
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 clamping at 12.5A (8/20μs); 1.5Ω dynamic resistance; 100pF capacitance. | Higher clamping voltage rises further with temperature and current; limited to ≤12.5A surge; unsuitable for 40A industrial surges. | Use only where cost is primary constraint and surge energy is low (e.g., consumer USB ports without PD). |
| TDS2211P.C | Same die, identical electrical specs, but commercial-grade (–40°C to +85°C) and non-military screened; same DFN package and pinout. | No military qualification (MIL-PRF-19500/560); lacks JANTX screening for radiation hardness and extended temperature testing. | Select JANTX1N6464US.TR for aerospace, defense, or high-reliability industrial deployments requiring MIL-STD-883 compliance. |

FAQ
What is the clamping voltage behavior of JANTX1N6464US.TR across temperature and current?
JANTX1N6464US.TR maintains a clamping voltage of 27.5–28V from –40°C to +125°C and across its full 24A–40A peak pulse current range. This flat response results from its active FET-based architecture, unlike TVS diodes whose clamping rises linearly with both current and temperature. The JANTX1N6464US.TR datasheet confirms this stability via test data across all operating conditions.
Is JANTX1N6464US.TR pin-compatible with standard TVS diodes like SMAJ22A?
No, JANTX1N6464US.TR is not pin-compatible with SMAJ22A or other two-terminal TVS diodes. It uses a 6-pin DFN package with three dedicated GND pins (1–3) and three parallel IN pins (4–6), requiring specific PCB layout with wide copper pours and multiple vias. SMAJ22A uses a DO-214AC package with anode/cathode configuration - direct replacement is electrically and mechanically invalid.
Can JANTX1N6464US.TR be used on high-speed data lines such as USB SuperSpeed or PCIe?
No, JANTX1N6464US.TR is not suitable for high-speed data lines. Its 175pF junction capacitance at 22V would severely degrade signal integrity on differential pairs operating above 100MHz. It is designed exclusively for DC power rails and low-speed control lines. For USB SS or DP/DM protection, Semtech recommends RClamp3371ZC (<0.25pF) instead of JANTX1N6464US.TR.
What is the significance of the "JANTX" prefix in JANTX1N6464US.TR?
The "JANTX" prefix indicates that JANTX1N6464US.TR is a military-qualified version per MIL-PRF-19500/560, including extended temperature screening (–55°C to +150°C storage, –40°C to +125°C operation), radiation hardness assurance, and lot-level traceability. This distinguishes it from commercial variants like TDS2211P.C and validates its use in aerospace, defense, and critical infrastructure applications.
How does JANTX1N6464US.TR protect load switches in industrial equipment?
JANTX1N6464US.TR protects load switches by clamping transient voltages to ≤28V before they reach the switch's input terminal - well below typical absolute maximum ratings (e.g., 30–36V). Its 20mΩ dynamic resistance ensures minimal overshoot during fast transients, preventing gate oxide damage or overvoltage lockout. Real-world validation shows JANTX1N6464US.TR enables reliable operation of HS2950P and similar switches in remote metering and robotics applications.
