Product details
Overview
JANTX1N6162AUS 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 ultra-low 20mΩ dynamic resistance - deployed in USB PD, Type-C, and industrial load-switch input protection.
For engineers reviewing the JANTX1N6162AUS datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature (-40°C to +125°C), constant VC under varying IPP, low junction capacitance (175pF), and DFN 1.6×1.6mm 6-lead package compatibility with space-constrained USB and IoT designs.
Technical Context
The JANTX1N6162AUS implements 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 VBR (~27.9V typ). Unlike conventional TVS diodes, its clamping voltage remains nearly flat (27.5–28V) from 24A to 40A due to decreasing RDS(on) under surge conditions.
It operates with reverse stand-off voltage (VRWM) of 22V, breakdown voltage (VBR) ≥25V at 1mA, and reverse leakage <600nA at 22V. Its functional architecture separates trigger sensing (voltage reference) from power handling (low-RDS(on) FET), enabling stable performance across -55°C to +150°C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage it can protect without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures protected ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surges. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial and USB PD applications. |

FAQ
What is the primary protection function of JANTX1N6162AUS?
JANTX1N6162AUS functions as a transient diverting suppressor that shunts high-energy electrical overstress (EOS) events-such as ESD, lightning-induced surges, and EFT-to ground using a precision-triggered FET. Unlike TVS diodes, it maintains a near-constant 27.5–28V clamping voltage across its full 40A peak pulse current range and operating temperature span, making JANTX1N6162AUS ideal for protecting sensitive 22V power rails in USB PD and industrial systems.
How does JANTX1N6162AUS differ from commercial TDS2211P?
JANTX1N6162AUS is the MIL-PRF-19500/616 qualified version of TDS2211P, undergoing rigorous Class H screening including extended burn-in, temperature cycling, and lot acceptance testing. Electrically identical, JANTX1N6162AUS provides full military traceability, certified test reports per MIL-STD-750, and guaranteed performance in defense and aerospace applications where commercial-grade parts are insufficient.
What is the recommended PCB layout for JANTX1N6162AUS?
Place JANTX1N6162AUS as close as possible to the protected connector (e.g., USB-C receptacle). Connect all three IN pins (4,5,6) via a single short, wide trace to the protected line, and tie all three GND pins (1,2,3) directly to a solid ground plane using multiple vias. Avoid thermal relief on GND pads and minimize trace inductance - this layout ensures JANTX1N6162AUS achieves its rated 40A surge capability and optimal clamping response.
Can JANTX1N6162AUS be used on data lines like USB 2.0 D+/D−?
No - JANTX1N6162AUS is optimized for power-line or high-energy I/O protection (e.g., VBUS, load switch inputs) with 175pF junction capacitance, which would distort high-speed signals. For USB 2.0 data lines, Semtech recommends low-capacitance TVS devices such as RClamp3371ZC (<0.25pF). JANTX1N6162AUS should only be applied to 22V-rated power or robust control lines where bandwidth is not critical.
What surge standards does JANTX1N6162AUS meet?
JANTX1N6162AUS meets IEC 61000-4-2 (±30kV contact/air ESD), IEC 61000-4-4 (±4kV EFT), and IEC 61000-4-5 (40A, 8/20μs; ±1kV, 1.2/50μs with 42Ω source) - covering the full spectrum of electromagnetic compatibility requirements for industrial, computing, and USB PD equipment. Its 1120W peak pulse power rating exceeds Level 4 surge immunity thresholds defined in EN 61000-4-5.
