Product details

Overview

JANTXV1N5806US 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, 20mΩ dynamic resistance, and 175pF junction capacitance - deployed in USB PD, USB Type-C, and industrial load-switch input protection.

For engineers reviewing the JANTXV1N5806US datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, real-world clamping stability across temperature and current, and direct alternatives for 22V bus protection with low-voltage clamping integrity.

Technical Context

The JANTXV1N5806US 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) across 24–40A IPP and −40°C to +125°C due to decreasing R_DS(on) under surge conditions.

It operates as a bidirectional shunt device with three IN terminals (pins 4–6) and three GND terminals (pins 1–3), requiring all six pins to be connected for full 40A rating. Its 175pF capacitance at 22V and 1MHz supports high-speed interfaces without signal distortion, while 130–600nA reverse leakage ensures minimal standby power impact.

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TDS2211P.C	Same die, commercial-grade (−40°C to +85°C), identical electrical specs and pinout	Not qualified for military/aerospace extended temperature or reliability screening	Select for cost-sensitive industrial or consumer designs where MIL-PRF-19500 compliance is unnecessary
SMAJ22A	Standard unidirectional TVS diode; 35.1V clamping at 12.9A (8/20μs); higher dynamic resistance (~0.5Ω)	Lacks constant-clamp behavior - clamping rises to ~42V at 40A and degrades above 85°C	Choose only if board space allows larger SMA package and design can tolerate higher clamping voltage margin

Compared with TDS2211P.C and SMAJ22A, JANTXV1N5806US provides military-grade temperature range (−55°C to +150°C), enhanced reliability screening per MIL-PRF-19500, and guaranteed constant clamping performance - making it the sole option for avionics, defense electronics, and high-reliability industrial control systems requiring sustained 22V rail protection.

FAQ

What is the maximum continuous operating voltage for JANTXV1N5806US?

JANTXV1N5806US has a reverse stand-off voltage (V_RWM) of 22V, meaning it can continuously block up to 22V DC or RMS without entering conduction. This makes JANTXV1N5806US suitable for 20V USB PD systems and 22V industrial power rails where reliable non-triggering operation is required under nominal conditions.

How does JANTXV1N5806US achieve constant clamping voltage across varying surge currents?

JANTXV1N5806US achieves constant clamping via a surge-rated FET activated by a precision trigger circuit. As peak pulse current increases, the FET's R_DS(on) decreases, counteracting voltage rise - resulting in 27.5–28V clamping from 24A to 40A. This behavior is confirmed in the JANTXV1N5806US datasheet Figure 3 and differs fundamentally from TVS diodes governed by V_C = V_BR + I_PP × R_DYN.

Is JANTXV1N5806US pin-compatible with commercial TDS2211P.C?

Yes, JANTXV1N5806US shares identical 6-pin DFN 1.6mm × 1.6mm package, pin configuration (pins 1–3 = GND, pins 4–6 = IN), and footprint with TDS2211P.C. However, JANTXV1N5806US undergoes MIL-PRF-19500 screening for extended temperature (−55°C to +150°C) and reliability - no PCB changes are needed when upgrading from TDS2211P.C to JANTXV1N5806US in high-reliability designs.

What is the junction capacitance of JANTXV1N5806US and how does it affect signal integrity?

JANTXV1N5806US exhibits 175pF junction capacitance at 22V and 1MHz. This value is appropriate for protecting low-to-mid-speed power and control lines (e.g., USB 2.0, SMBus, GPIO), but not recommended for high-speed differential pairs like USB 3.x SuperSpeed or PCIe Gen4/5, where sub-1pF capacitance is required to avoid insertion loss and jitter.

Can JANTXV1N5806US protect bidirectional data lines such as USB CC or SBU?

No - JANTXV1N5806US is optimized for unidirectional or bidirectional power rail protection (e.g., V_Bus, load switch input), not low-capacitance data line protection. For CC/SBU lines, Semtech recommends uClamp2411ZA (24V, <15pF); JANTXV1N5806US's 175pF capacitance would severely degrade signal integrity on those differential or single-ended data paths.
