Product details
Overview
JANTXV1N6161AUS 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 features ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping at 40A, 20mΩ dynamic resistance, and 175pF junction capacitance - enabling robust protection in USB PD, industrial IoT, and aerospace power bus applications.
For engineers reviewing the JANTXV1N6161AUS datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, real-world clamping stability across temperature, and validated alternatives for MIL-PRF-19500/563-compliant designs.
Technical Context
JANTXV1N6161AUS implements a solid-state transient diverting architecture using a surge-rated FET as the primary shunt element, activated by a precision trigger circuit - unlike conventional TVS diodes, its clamping voltage remains nearly constant (27.5–28V) from 24A to 40A and across −40°C to +125°C due to sub-0.1Ω RDS(on) collapse under surge.
The device operates with a 22V reverse stand-off voltage (VRWM) and 25–27.9V breakdown (VBR at 1mA), supports unsymmetrical line protection per IEC 61000-4-5 (±1kV, 1.2/50μs), and delivers 1120W peak pulse power handling while maintaining low leakage (<600nA at 22V) and stable 175pF capacitance at 1MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-Off Voltage | 22 V - defines maximum continuous operating voltage before conduction begins; matches 20V USB PD bus with 10% margin. |
| Clamping Voltage @ 40A | 27.5–28 V - ensures protected ICs (e.g., USB PD controllers) remain below 30V damage threshold during worst-case surges. |
| Peak Pulse Current | 40 A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements without derating. |
| Dynamic Resistance | 20 mΩ - enables flat clamping curve; reduces voltage rise per amp vs. TVS diodes (which exhibit linear VC = VBR + IPP×RDYN). |
| Junction Capacitance | 175 pF @ 22V, 1MHz - compatible with DC power rails and low-speed I/O; avoids signal integrity issues on USB CC/SBU lines. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds Level 4 ESD immunity for ruggedized industrial and aerospace interfaces. |
| Operating Temperature | −40°C to +125°C - supports extended-range operation in avionics, motor drives, and outdoor IoT edge nodes. |
Pinout & Package
Package: DFN-6 (1.6 mm × 1.6 mm × 0.55 mm), RoHS/WEEE compliant, UL 94V-0 molding compound, lead-free finish, tape-and-reel packaging (3,000 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground terminals - all three must be connected to minimize parasitic inductance and maximize 40A surge current path to PCB ground plane. |
| 4, 5, 6 | IN | Protected line input - pins electrically parallel; single straight trace from connector required to preserve low-inductance path for fast transients. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies <0.5V from 24A to 40A - eliminates need for over-specifying IPP to meet voltage limits. |
| Temperature-stable protection | Clamping remains 27.5–28V from −40°C to +125°C - removes thermal derating calculations required for standard TVS diodes. |
| Low dynamic resistance | 20mΩ enables <1V additional drop at 40A - critical for protecting 22V-rated load switches and e-fuses without overvoltage stress. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) - sustains repeated lightning-induced surges in industrial fieldbus and remote metering systems. |
| MIL-PRF-19500/563 qualified | Meets JANTXV screening for vibration, shock, hermeticity, and lot traceability - required for defense and spaceflight power rail protection. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|

Use Scenario: Securing RS-485 and power input lines of utility smart meters installed in outdoor substations subject to lightning-induced surges. IC Role / Device Role / Timing Role: First-line defense against 8/20μs surges coupled via long cable runs into meter's DC input stage. Use Value: 40A rating and 1120W peak power dissipation prevent catastrophic failure during repeated 10kA lightning current injections per IEC 61000-4-5. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Commercial-grade DFN-6 variant; same 22V VRWM, 27.5–28V clamping, 40A rating, but not MIL-screened. | Lacks JANTXV qualification; suitable for commercial USB PD and IoT where cost and volume outweigh military reliability needs. | Select TDS2211P for non-military production with identical electrical performance and smaller footprint. |
| SMCJ22A | Standard unidirectional TVS diode; higher clamping (36.5V @ 40A), 1.5× larger SMC package, 10× higher dynamic resistance (~200mΩ). | Exhibits rising clamping with temperature and current - requires derating for high-temp industrial use. | Choose SMCJ22A only when legacy board space allows larger package and design can tolerate 36.5V clamping at 125°C. |
Compared with JANTXV1N6161AUS, TDS2211P offers identical protection performance in a commercial-grade package, while SMCJ22A trades clamping precision and thermal stability for broad industry familiarity and higher surge energy tolerance in a larger form factor.

FAQ
What is the clamping voltage of JANTXV1N6161AUS at 40A surge current?
JANTXV1N6161AUS clamps at 27.5–28V under 40A peak pulse current (8/20μs waveform), measured with 2Ω source impedance. This value remains stable across −40°C to +125°C, distinguishing it from conventional TVS diodes whose clamping rises with temperature and current. The consistent 27.5V ceiling ensures downstream 30V-rated ICs like USB PD controllers operate safely even under worst-case surge conditions.
Is JANTXV1N6161AUS pin-compatible with TDS2211P?
Yes, JANTXV1N6161AUS and TDS2211P share identical DFN-6 (1.6 mm × 1.6 mm) package dimensions, pin numbering, and terminal assignment: pins 1–3 are GND, pins 4–6 are IN. Both require all six pins to be soldered for full 40A surge capability. However, JANTXV1N6161AUS undergoes MIL-PRF-19500/563 screening including burn-in, thermal shock, and hermeticity testing - making it suitable for defense and space applications where TDS2211P is not qualified.
Does JANTXV1N6161AUS support bidirectional or unidirectional protection?
JANTXV1N6161AUS provides unidirectional protection optimized for positive-going transients on 22V DC rails. Its functional architecture uses a precision-triggered shunt FET activated only when voltage exceeds the 25–27.9V breakdown threshold - it does not conduct under reverse bias beyond VRWM. For bidirectional data-line protection (e.g., USB DP/DM), complementary low-capacitance TVS devices like RClamp3371ZC must be used alongside JANTXV1N6161AUS on power lines.
What is the maximum junction temperature rating for JANTXV1N6161AUS?
JANTXV1N6161AUS has a junction and storage temperature range of −55°C to +150°C, with continuous operating temperature specified from −40°C to +125°C. This extended range supports deployment in engine compartments, avionics bays, and outdoor industrial enclosures. The device's clamping voltage remains stable across this full operating span - a key advantage over standard TVS diodes whose VC increases significantly above 85°C.
Can JANTXV1N6161AUS replace SMCJ22A in existing designs?
JANTXV1N6161AUS can replace SMCJ22A electrically but requires PCB layout revision due to its DFN-6 (1.6 mm × 1.6 mm) footprint versus SMCJ22A's SMC (7.11 mm × 6.22 mm) package. While both handle 40A surges, JANTXV1N6161AUS clamps at 27.5V vs. SMCJ22A's 36.5V - offering tighter voltage control. Designers must verify thermal relief and ground plane connectivity for the smaller DFN package, especially in high-reliability applications where JANTXV screening adds value.
