Product details
Overview
JANTXV1N5811 from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection on 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 JANTXV1N5811 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 in USB Type-C, IoT, and industrial equipment designs.
Technical Context
The JANTXV1N5811 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 24–40A (8/20μs) due to decreasing RDS(on) under surge conditions.
It operates from −40°C to +125°C with stable 27.5–28V clamping up to 125°C, 22V reverse stand-off voltage, and 175pF junction capacitance at 22V/1MHz - enabling robust protection without thermal derating penalties seen in standard TVS devices.
Key Specifications

|---|---|
Use Scenario: Protecting VBUS lines in USB-C ports supporting up to 20V/5A PD negotiation against ESD and lightning-induced surges. IC Role / Device Role / Timing Role: Primary front-end transient suppressor placed directly at the connector, shunting EOS energy before it reaches the PD controller or buck converter. Use Value: Maintains 27.5–28V clamping across temperature and current range, preventing damage to 30V-rated PD controllers even at 125°C ambient. |
Use Scenario: Safeguarding the input of high-side load switches (e.g., HS2950P) in remote meters, robotics, and factory automation systems. IC Role / Device Role / Timing Role: Surge diverter placed upstream of the load switch FET to limit drain-source voltage during transients and avoid avalanche failure. Use Value: 20mΩ dynamic resistance limits overshoot to <1.1V at 40A, keeping VDS below 29V and preserving FET reliability under repeated surge stress. |
| IoT Edge Node Power Rails | Industrial Equipment DC Inputs |
Use Scenario: Securing 22V-rated auxiliary power inputs on battery-backed wireless sensors exposed to ESD during field servicing or lightning-coupled surges. IC Role / Device Role / Timing Role: Single-device EOS protector for unregulated DC inputs, replacing multi-component TVS+RC networks. Use Value: ±30kV ESD rating and 40A surge capacity eliminate need for external filtering, reducing BOM count and PCB area in space-constrained nodes. |
Use Scenario: Hardening 24V DC inputs on PLC modules, motor drives, and HMI panels against induced surges in factory floor environments. IC Role / Device Role / Timing Role: Industrial-grade transient suppressor compliant with IEC 61000-4-5 Level 4 (±1kV, 42Ω source) for mains-connected equipment. Use Value: Stable clamping at 125°C allows placement near heat-generating components without derating, simplifying thermal layout. |
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 specs, commercial-grade qualification (non-military). | Not qualified to MIL-PRF-19500/560; lacks JANTXV screening and extended temp testing. | Select when cost-sensitive commercial designs require identical performance without military screening. |
| Littelfuse SP3022-01FTG | TVS diode (not TDS architecture); 22V VRWM, 33.2V VC @ 24A, 300pF capacitance. | Higher clamping voltage (+5.7V), no temperature stability guarantee, unsuitable for 125°C sustained operation. | Acceptable only where clamping margin >33V exists and ambient stays ≤85°C. |
Compared with JANTXV1N5811, TDS2211P offers identical protection performance at lower cost but lacks military screening, while SP3022-01FTG requires larger voltage margin and cannot maintain clamping stability above 85°C - making JANTXV1N5811 the sole choice for extended-temperature, low-clamp industrial and aerospace-adjacent applications.

FAQ
What is the maximum operating temperature for JANTXV1N5811?
JANTXV1N5811 is rated for continuous operation from −40°C to +125°C. Its clamping voltage remains tightly controlled between 27.5V and 28V across this full range, confirmed by characterization data in the official Semtech datasheet Rev 2.5. This makes JANTXV1N5811 suitable for under-hood automotive auxiliary systems and sealed industrial enclosures where thermal management is constrained. The JANTXV1N5811 maintains full 40A surge capability at 125°C without derating.
How does JANTXV1N5811 differ from standard TVS diodes in clamping behavior?
JANTXV1N5811 uses a triggered FET-based architecture instead of a pn-junction diode, resulting in near-constant clamping voltage (27.5–28V) from 24A to 40A (8/20μs), unlike TVS diodes whose clamping rises linearly with current due to fixed dynamic resistance. This behavior is validated across −40°C to +125°C. The JANTXV1N5811 achieves this via decreasing RDS(on) under surge, delivering predictable protection margins impossible with conventional TVS devices.
What is the recommended PCB layout for JANTXV1N5811 to achieve full 40A surge rating?
To achieve the full 40A (8/20μs) rating, all three GND pins (1, 2, 3) and all three IN pins (4, 5, 6) must be connected with low-inductance traces - ideally using a solid ground plane and multiple vias beneath the GND pads. The device must be placed within 5mm of the protected connector. Splitting or omitting any pin connection reduces surge current handling and degrades clamping consistency. This layout requirement is explicitly defined in the JANTXV1N5811 datasheet Figure 7 and applies identically to the JANTXV1N5811.
Is JANTXV1N5811 suitable for protecting USB SuperSpeed differential pairs?
No, JANTXV1N5811 is not suitable for USB SuperSpeed (SS) TX/RX differential pairs. Its 175pF junction capacitance at 22V would severely distort >5Gbps signals. It is intended exclusively for DC power rails (e.g., VBUS) and low-speed control lines. For SS lane protection, Semtech recommends sub-0.25pF devices like RClamp3371ZC - a distinction clearly documented in the JANTXV1N5811 application note section on USB Type-C protection architecture.
Does JANTXV1N5811 require an external bias or control signal to operate?
No, JANTXV1N5811 is fully passive and requires no external bias, enable signal, or configuration. Its internal trigger circuit activates automatically when transient voltage exceeds the breakdown threshold, turning on the shunt FET to divert surge current to ground. This autonomous operation is inherent to the TDS architecture and confirmed across all test conditions in the JANTXV1N5811 datasheet - no external components or power are needed for JANTXV1N5811 to deliver full 40A protection.
