Product details
Overview
JANTX1N6081 from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 22V-rated I/O or power lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, 20mΩ dynamic resistance, and 175pF junction capacitance - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the JANTX1N6081 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, temperature-stable clamping behavior, and direct alternative options for 22V bus protection in high-reliability embedded and industrial systems.
Technical Context
JANTX1N6081 implements a surge-rated FET-based shunt architecture with a precision trigger circuit that activates the low-RDS(on) FET during overvoltage events, enabling near-constant clamping voltage across 0–40A and −40°C to +125°C. Unlike conventional TVS diodes, its clamping voltage remains stable due to decreasing FET on-resistance under increasing current.
The device operates as a bidirectional, single-line protector with pins 4–6 as the protected input path and pins 1–3 as ground terminals. Its 1.6mm × 1.6mm × 0.55mm DFN-6 package requires all six pins to be connected for full 40A surge rating and minimal parasitic inductance - critical for fast-rising ESD and lightning surge suppression.

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 +85°C) vs. JANTX1N6081's military-extended temperature range (−55°C to +150°C). | Not qualified to MIL-PRF-19500/560; lacks JANTX screening for burn-in, hermeticity, and lot traceability. | Select JANTX1N6081 for aerospace, defense, or high-reliability industrial programs requiring MIL-spec qualification. |
| Littelfuse SP3022-01WTG | TVS diode (not FET-based); 24V working voltage, 33V clamping at 12A, 12pF capacitance - higher clamping, lower current, much lower capacitance. | Better suited for high-speed data lines (e.g., USB 2.0 DM/DP), not power rails requiring >20A surge handling. | Choose SP3022-01WTG only when ultra-low capacitance (<15pF) is mandatory and peak current demand is <15A. |
Compared with TDS2211P.C and SP3022-01WTG, JANTX1N6081 uniquely combines military-grade temperature range, FET-based constant-clamp performance, and 40A surge capacity - making it the sole option for ruggedized 22V power rail protection where both reliability and electrical consistency are non-negotiable.

FAQ
What is the maximum clamping voltage of JANTX1N6081 at 40A surge current?
JANTX1N6081 clamps at 27.5–28 V under 40A peak pulse current (8/20μs waveform, 2Ω source impedance), as confirmed in the Semtech datasheet Absolute Maximum Ratings and Electrical Characteristics tables. This value remains stable across −40°C to +125°C, distinguishing it from conventional TVS diodes whose clamping rises with temperature and current.
Does JANTX1N6081 require external biasing or control signals to operate?
No, JANTX1N6081 is a fully passive, self-triggering device. It contains an integrated precision trigger circuit and surge-rated FET - no external voltage, enable pin, or configuration is needed. The device automatically activates when input voltage exceeds its 25–27.9V breakdown threshold, diverting surge current to ground without any user intervention or power supply.
Can JANTX1N6081 be used on high-speed data lines like USB 3.2 or PCIe?
No, JANTX1N6081 is not suitable for high-speed data lines. Its 175pF junction capacitance at 22V would severely degrade signal integrity above ~10 MHz. It is specifically designed for DC or low-frequency power rails (e.g., USB PD VBus, load switch inputs). For data line protection, Semtech recommends RClamp3371ZC (0.25pF) or similar low-capacitance TVS devices.
What is the meaning of "JANTX" prefix in JANTX1N6081?
The "JANTX" prefix indicates compliance with MIL-PRF-19500/560, denoting a military-qualified version of the commercial TDS2211P with enhanced screening: extended temperature range (−55°C to +150°C), 100% lot testing, burn-in, hermetic packaging options, and full traceability. JANTX1N6081 meets requirements for aerospace, defense, and high-reliability industrial applications.
How should PCB layout be optimized for JANTX1N6081 to achieve full 40A surge rating?
To achieve the full 40A rating, connect all three GND pins (1, 2, 3) to a solid ground plane using multiple vias, and tie all three IN pins (4, 5, 6) together with a short, wide copper trace directly at the protected connector. Place JANTX1N6081 within 5 mm of the entry point. Avoid stubs or narrow traces - parasitic inductance degrades clamping response and reduces effective surge current handling.
