Product details
Overview
JTXV1N5822US from Semtech is a transient diverting suppressor designed for high-energy EOS protection on 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A (8/20μs) peak pulse current handling, 27.5–28V clamping voltage at 40A, and DFN 1.6×1.6×0.55mm 6-lead package - deployed in USB Type-C PD input protection and industrial load switch front-end surge suppression.
For engineers reviewing the JTXV1N5822US datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability across temperature and current, dynamic resistance ≤20mΩ, junction capacitance of 175pF at 22V, and verified 6-pin DFN layout compatibility with high-current ground and input routing per Semtech's PCB guidelines.
Technical Context
JTXV1N5822US 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 (27.5–28V) from 24A to 40A due to decreasing RDS(on) under surge conditions.
The device operates over –40°C to +125°C, maintains stable clamping across temperature (±0.2V variation), and achieves 1120W peak pulse power rating with 20mΩ dynamic resistance measured between 1A and 40A (8/20μs). Its 175pF junction capacitance at 22V and 1MHz is optimized for 22V bus protection without signal integrity compromise in DC/low-frequency applications.
Key Specifications

FAQ
What is the maximum continuous operating voltage for JTXV1N5822US?
JTXV1N5822US has a reverse stand-off voltage (VRWM) of 22V, meaning it can reliably block up to 22V DC or RMS voltage in normal operation without significant leakage. This makes JTXV1N5822US ideal for protecting 22V power buses such as USB-C PD VBus and industrial 24V nominal systems operating within derated margins.
How does JTXV1N5822US achieve stable clamping voltage across temperature?
JTXV1N5822US uses a precision-triggered FET shunt architecture instead of a pn-junction diode. When an EOS event occurs, the trigger circuit activates the low-RDS(on) FET, whose on-resistance decreases with increasing current - counteracting thermal voltage drift. As a result, JTXV1N5822US maintains clamping within 27.5–28V from –40°C to +125°C, unlike conventional TVS devices whose VC rises with temperature.
Can JTXV1N5822US be used on high-speed data lines like USB SuperSpeed?
No - JTXV1N5822US is not suitable for high-speed data lines. Its 175pF junction capacitance at 22V is optimized for DC and low-frequency power rail protection. For USB SuperSpeed (TX/RX), USB 3.x, or DisplayPort lines, Semtech recommends low-capacitance TVS devices such as RClamp3371ZC (<0.25pF). JTXV1N5822US should be applied only to VBus, CC, SBU, or other low-bandwidth 22V signals.
What is the recommended PCB layout for JTXV1N5822US to achieve full 40A rating?
To achieve the full 40A (8/20μs) rating, all three GND pins (1, 2, 3) and all three IN pins (4, 5, 6) of JTXV1N5822US must be connected in parallel using short, wide copper traces. Ground connections should route to a solid ground plane via ≥3 vias per GND pin. Place JTXV1N5822US within 5mm of the protected connector to minimize inductive coupling - layout guidance is validated in Semtech's TDS2211P reference design.
Is JTXV1N5822US RoHS and REACH compliant?
Yes - JTXV1N5822US is Pb-free, halogen-free, and fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Its molding compound meets UL 94V-0 flammability rating, and lead finish is matte tin. Compliance documentation, including test reports and declarations, is available through Aetrix Electronics' component traceability portal for JTXV1N5822US.
