Product details
Overview
JANTX1N5552US.TR 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 DFN 1.6×1.6×0.55mm 6-lead package - deployed in USB Type-C PD input protection and industrial load switch inputs.
For engineers reviewing the JANTX1N5552US.TR datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability across temperature and peak current, dynamic resistance under surge, junction capacitance for signal integrity, and validated performance in ±1kV IEC 61000-4-5 unsymmetrical line testing.
Technical Context
The JANTX1N5552US.TR 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 breakdown threshold. Unlike conventional TVS diodes, its clamping voltage remains nearly constant due to decreasing RDS(on) under increasing IPP.
It operates with reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V at 1mA, and maintains stable clamping (27.5–28V) across –40°C to +125°C and 24–40A IPP range. Its 20mΩ dynamic resistance and 175pF junction capacitance at 22V/1MHz support robust surge handling without signal degradation in high-speed bus interfaces.
Key Specifications

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 silicon die, commercial-grade temperature range (–40°C to +85°C) and qualification level; identical electrical specs and pinout. | Not qualified for extended temperature or military screening; unsuitable for aerospace or defense programs requiring JANTX screening. | Select JANTX1N5552US.TR when MIL-PRF-19500/565 Class H screening, extended temp validation, or traceable lot documentation is required. |
| SMAJ22A | Standard unidirectional TVS diode; 38V clamping at 24A/125°C; higher dynamic resistance (~0.5Ω); no FET-based regulation. | Lacks constant-clamp behavior - clamping rises with temperature and current; requires larger derating margin in thermally constrained designs. | Choose SMAJ22A only if cost sensitivity outweighs clamping stability, and design allows ≥10V margin above protected IC's absolute max rating. |
Compared with TDS2211P.C and SMAJ22A, JANTX1N5552US.TR provides military-grade reliability and consistent 27.5–28V clamping across temperature and current - critical for mission-critical industrial and defense systems where surge response predictability cannot be compromised.

FAQ
What is the clamping voltage specification for JANTX1N5552US.TR at maximum rated surge current?
JANTX1N5552US.TR clamps at 27.5–28V when subjected to 40A peak pulse current (8/20μs + 1.2/50μs combination waveform, RS = 2Ω). This value is guaranteed across –40°C to +125°C and reflects the device's FET-based architecture, which maintains near-constant clamping unlike traditional TVS diodes whose voltage rises with current and temperature.
Is JANTX1N5552US.TR pin-compatible with standard TVS diodes like SMAJ22A?
No, JANTX1N5552US.TR is not pin-compatible with SMAJ22A. JANTX1N5552US.TR uses a 6-pin DFN package with three parallel input pins (4–6) and three parallel ground pins (1–3), whereas SMAJ22A is a 2-pin DO-214AC package. PCB layout, trace routing, and grounding strategy must be redesigned to accommodate the DFN footprint and multi-pin configuration of JANTX1N5552US.TR.
Does JANTX1N5552US.TR meet IEC 61000-4-5 Level 4 surge immunity requirements?
Yes, JANTX1N5552US.TR is rated for 40A (8/20μs) and ±1kV (1.2/50μs, RS = 42Ω) per IEC 61000-4-5, satisfying Level 4 requirements for unsymmetrical lines. Its 27.5–28V clamping voltage ensures protected downstream components remain within safe operating limits during such events, making it suitable for industrial equipment and outdoor infrastructure.
What is the junction capacitance of JANTX1N5552US.TR and how does it affect high-speed signal lines?
JANTX1N5552US.TR has a junction capacitance of 175pF at 22V and 1MHz. While this value is appropriate for 22V power rails and low-to-medium speed control lines, it is not intended for direct placement on high-speed differential pairs (e.g., USB SS, PCIe, SATA). For those, Semtech recommends pairing JANTX1N5552US.TR with ultra-low-capacitance devices like RClamp3371ZC on data lanes.
How does the FET-based architecture of JANTX1N5552US.TR improve protection compared to standard TVS diodes?
JANTX1N5552US.TR replaces the pn-junction of standard TVS diodes with a surge-rated FET and precision trigger circuit. This yields 20mΩ dynamic resistance and flat clamping voltage (27.5–28V) across 24–40A and –40°C to +125°C - eliminating the linear VC = VBR + IPP × RDYN rise seen in TVS diodes. As a result, JANTX1N5552US.TR delivers predictable, temperature-stable protection without derating.
