Product details
Overview
JANTX1N6465 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. It protects USB PD, Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the JANTX1N6465 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, temperature-stable clamping behavior, and direct alternatives for 22V bus protection design-in.
Technical Context
JANTX1N6465 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 across 0–40A (8/20μs) due to decreasing RDS(on) under surge conditions.
The device operates from −40°C to +125°C with stable 27.5–28V clamping at 40A, 22V reverse stand-off, and 27.9V typical breakdown. Its 175pF junction capacitance at 22V/1MHz and 600nA max leakage support low-noise, high-speed line protection without signal integrity compromise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD VBus and industrial 24V rail derating margins |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - stays below 30V damage threshold of common load switches and PD controllers |
| 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 consumer ESD requirements |
| Dynamic Resistance | 20mΩ - enables flat clamping curve and minimizes voltage overshoot during fast transients |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for USB PD CC/SBU and industrial sensor bus protection |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS-compliant, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return for surge current; all three must be connected to maximize 40A capability and minimize parasitic inductance |
| 4, 5, 6 | IN | Protected line input (e.g., USB PD VBus); parallel connection ensures uniform current sharing and thermal distribution |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies <0.5V from 24A to 40A - eliminates need for overrating IPP to meet voltage limits |
| Temperature-stable protection | Clamping holds 27.5–28V from −40°C to +125°C - removes derating uncertainty in industrial thermal environments |
| Low dynamic resistance | 20mΩ enables sub-1V overshoot during 10ns rise-time ESD events - critical for protecting sensitive PD controllers |
| DFN-6 space efficiency | 1.6mm × 1.6mm footprint saves >60% board area vs. SO-8 TVS solutions - ideal for compact USB-C connectors and IoT modules |
Applications
| USB Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting 20–22V USB PD VBus lines against lightning-induced surges and connector ESD during hot-plug events. IC Role / Device Role / Timing Role: Primary shunt protector placed directly at Type-C receptacle, clamping transients before they reach the PD controller or e-fuse. Use Value: Maintains 27.5V clamping at full 40A surge and 125°C ambient - prevents latch-up or gate oxide damage in downstream SiC/GaN PD controllers. |
Use Scenario: Safeguarding enable and input pins of industrial-grade load switches (e.g., HS2950P) exposed to 42Ω/0.5μF surge coupling in metering or robotics. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage seen by the load switch's internal FET gate and drain terminals. Use Value: Prevents gate-source overvoltage failure and drain-source avalanche stress by holding clamp <28V - extends reliability beyond IEC 61000-4-5 compliance. |
| IoT Sensor Hub Power Rail Protection | Notebook/Tablet DC-DC Input Protection |
|
Use Scenario: Securing 22V auxiliary rails powering cellular modems or environmental sensors in outdoor-connected devices. IC Role / Device Role / Timing Role: Single-device solution for combined ESD, EFT, and surge protection on shared power buses feeding multiple subsystems. Use Value: ±4kV EFT immunity (IEC 61000-4-4) and 40A surge rating ensure uninterrupted operation in electrically noisy factory or smart-city deployments. |
Use Scenario: Protecting buck converter inputs in ultrabooks and tablets where space-constrained layouts limit discrete TVS placement near DC jack or battery interface. IC Role / Device Role / Timing Role: Compact, low-capacitance shunt suppressor integrated into tight PCB areas adjacent to power entry points. Use Value: 175pF capacitance avoids degrading switching node stability; DFN-6 allows placement within 2mm of connector - reducing loop inductance by >40%. |
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 architecture | Larger 400mW package; higher clamping voltage increases risk of downstream IC damage at elevated temperatures | Use only where cost sensitivity outweighs clamping precision and thermal stability requirements |
| TPD2E007DRYR | Low-capacitance (1.5pF) dual-channel ESD array; rated for 3A (8/20μs), not surge-rated | Designed for data-line ESD only; lacks 40A surge capability and 22V working voltage rating | Select for USB SS/DP/DM lines only - never as VBus replacement for JANTX1N6465 |
Compared with SMAJ22A and TPD2E007DRYR, JANTX1N6465 uniquely delivers 40A surge handling with <28V clamping across temperature, making it the sole option for robust 22V bus protection where thermal derating and voltage margin are critical.

FAQ
What is the exact clamping voltage of JANTX1N6465 at 40A surge current?
JANTX1N6465 clamps at 27.5–28V under 40A (8/20μs) combination waveform test conditions (RS = 2Ω). This value is guaranteed across −40°C to +125°C and reflects its FET-based constant-clamp architecture - not a typical TVS diode's linear VC = VBR + IPP × RDYN relationship. The JANTX1N6465 maintains this narrow window without thermal derating.
Does JANTX1N6465 require a thermal pad on the PCB?
No, JANTX1N6465 does not require a thermal pad. Its energy dissipation occurs primarily through conduction via the six copper leads and ground vias - not junction-to-case conduction. The datasheet explicitly states "no thermal pad is needed" because transient energy is handled by the shunt FET's low RDS(on), and thermal management relies on PCB copper mass and via count, not die attach area. JANTX1N6465 layout guidelines emphasize multi-via grounding instead.
Can JANTX1N6465 protect bidirectional data lines like USB DP/DM?
No, JANTX1N6465 is not suitable for bidirectional data lines. It is a unidirectional shunt suppressor optimized for 22V power or single-ended I/O lines (e.g., VBus, CC, SBU). Its 175pF junction capacitance and lack of low-capacitance differential configuration make it inappropriate for SuperSpeed USB or MIPI signaling. For DP/DM protection, Semtech recommends RClamp3371ZC (<0.25pF), not JANTX1N6465.
How does JANTX1N6465 differ from standard TVS diodes in temperature performance?
JANTX1N6465 maintains 27.5–28V clamping from −40°C to +125°C, whereas standard TVS diodes exhibit rising clamping voltage with temperature due to fixed dynamic resistance. At 125°C, a typical 22V TVS may clamp above 38V at 24A - exceeding safe thresholds for PD controllers. JANTX1N6465's FET-based architecture eliminates this drift, delivering consistent protection across full industrial temperature range - a key differentiator confirmed in Figure 3 of its datasheet.
Is JANTX1N6465 pin-compatible with other Semtech TDS devices like TDS2211P?
Yes, JANTX1N6465 shares identical pin configuration, package dimensions (DFN 1.6×1.6×0.55mm), and terminal assignment (Pins 1–3 = GND, Pins 4–6 = IN) with TDS2211P. Both are functionally and mechanically interchangeable per Semtech's documentation - enabling drop-in replacement in existing designs without PCB revision. JANTX1N6465 is the qualified military-grade variant of TDS2211P, meeting MIL-PRF-19500/565 requirements.
