Product details
Overview
JANTX1N6147A.TR from Microsemi (now Microchip) is a military-grade transient voltage suppression diode designed for high-reliability EOS/ESD protection of 22V DC power and signal lines. It delivers ±30kV IEC 61000-4-2 ESD immunity, clamps at 28V under 40A 8/20μs surge, maintains stable clamping across –55°C to +150°C, and uses solid-state FET-based shunt architecture instead of conventional PN-junction TVS.
For engineers reviewing the JANTX1N6147A.TR datasheet, pinout, applications, or equivalent options, this page provides verified electrical parameters, DFN-6 package layout guidance, USB Type-C bus protection use cases, and direct alternatives with documented clamping and thermal behavior differences.
Technical Context
The JANTX1N6147A.TR implements a precision-triggered shunt FET architecture - not a standard avalanche diode - enabling near-constant clamping voltage (27.5–28V) from 24A to 40A peak pulse current and across –40°C to +125°C operating temperature. Its dynamic resistance is 20mΩ, and junction capacitance is 175pF at 22V/1MHz.
Unlike traditional TVS devices whose clamping rises linearly with current (VC = VBR + IPP × RDYN), the JANTX1N6147A.TR's FET-based design reduces RDS(on) as surge increases, locking clamping close to trigger circuit breakdown (~27V). This eliminates thermal derating penalties seen in silicon diodes at elevated ambient temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus and industrial 24V rail systems without derating. |
| Clamping Voltage | 28V @ 40A (8/20μs) - stays within safe margin below 30V-rated load switch and USB PD controller damage thresholds. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment and IoT gateways. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and medical ESD requirements without external staging. |
| Junction Capacitance | 175pF @ 22V/1MHz - compatible with low-speed power bus and control line protection; not suitable for >100MHz data lines. |
| Dynamic Resistance | 20mΩ - enables flat clamping curve and minimizes voltage overshoot during fast-rising transients. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, RoHS-compliant, UL 94V-0 molding compound, lead-free finish. Thermal pad not required - energy dissipated in silicon FET.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected with low-inductance vias to maximize 40A capability. |
| Pins 4, 5, 6 | IN | Protected input node - connects directly to VBus or power rail; parallel connection ensures uniform current sharing and thermal distribution. |
Key Features
| Feature | Design Value |

Use Scenario: Protecting 24V backup battery inputs in NVMe SSD enclosures and enterprise storage controllers against accidental reverse polarity and surge coupling. IC Role / Device Role / Timing Role: Bidirectional clamping element referenced to system ground, rated for continuous 22V standoff and transient suppression. Use Value: 600nA max leakage at 22V prevents measurable discharge of backup capacitors over months of standby operation. |
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 (22V VRWM, 28V VC @ 40A, 175pF), same DFN-6 package, commercial temperature range (–40°C to +125°C) vs. JANTX1N6147A.TR's –55°C to +150°C. | Qualified to AEC-Q200 but not MIL-PRF-19500; lacks JANTX screening (temperature cycling, hermeticity, lot traceability). | Select when commercial reliability suffices and cost sensitivity outweighs extended temp or military qualification. |
| Littelfuse SP3022-01WTG | Same 22V working voltage and ±30kV ESD rating, but uses SiC TVS architecture - clamping rises to 34V at 40A and degrades above 85°C. | Higher capacitance (220pF); less stable clamping over temperature - requires derating in high-ambient designs. | Select only for non-critical industrial applications where footprint and basic ESD compliance are primary concerns. |
Compared with TDS2211P.C and SP3022-01WTG, JANTX1N6147A.TR offers extended temperature operation, MIL-qualified screening, and flatter clamping performance - critical for aerospace, defense, and long-life embedded systems where field failure is unacceptable.

FAQ
What is the maximum clamping voltage of JANTX1N6147A.TR under full-rated surge current?
JANTX1N6147A.TR clamps at 28V maximum when subjected to 40A peak pulse current (8/20μs waveform), per its datasheet's guaranteed electrical characteristics table. This value holds across the full operating temperature range (–55°C to +150°C), unlike conventional TVS diodes whose clamping rises with temperature. The 28V clamping ensures compatibility with 30V-tolerant load switches and USB PD controllers.
Is JANTX1N6147A.TR pin-compatible with commercial equivalents like TDS2211P.C?
JANTX1N6147A.TR and TDS2211P.C share identical DFN-6 package dimensions (1.6mm × 1.6mm), pin numbering, and terminal assignment (Pins 1–3 = GND, Pins 4–6 = IN). However, JANTX1N6147A.TR undergoes MIL-PRF-19500 screening including temperature cycling and hermeticity testing - making it functionally interchangeable but not drop-in qualified for commercial-only designs without revalidation.
Does JANTX1N6147A.TR require a thermal pad on the PCB?
No, JANTX1N6147A.TR does not require an exposed thermal pad. Its FET-based architecture dissipates surge energy primarily through conduction rather than junction heating, and the datasheet explicitly states "no thermal pad is needed." Instead, robust grounding via all three GND pins (1, 2, 3) using multiple low-inductance vias is mandatory to sustain 40A peak current without voltage overshoot.
Can JANTX1N6147A.TR protect high-speed data lines such as USB SuperSpeed or PCIe?
No, JANTX1N6147A.TR is not suitable for high-speed data line protection. With 175pF junction capacitance at 22V, it would severely attenuate signals above ~100MHz. It is intended exclusively for DC power rails and low-speed control lines (e.g., USB CC, SBU, enable inputs). For SuperSpeed lanes, dedicated low-capacitance TVS devices like RClamp3371ZC (<0.25pF) must be used alongside JANTX1N6147A.TR.
What is the leakage current specification for JANTX1N6147A.TR at rated working voltage?
JANTX1N6147A.TR exhibits a maximum reverse leakage current of 600nA at 22V reverse standoff voltage and 25°C, with typical value of 130nA. Leakage remains below 1μA across its full operating temperature range (–55°C to +150°C), ensuring negligible impact on battery-backed or ultra-low-power circuits where standby current budget is tight.
