Product details
Overview
JANTXV1N5552 from Microsemi (now Microchip) is a military-grade silicon planar passivated junction diode optimized for high-reliability transient voltage suppression in 22V DC bus protection applications. It delivers ±30kV IEC 61000-4-2 ESD immunity, clamps at 27.5–28V under 40A 8/20μs surge, and maintains stable dynamic resistance of 20mΩ across -40°C to +125°C - enabling robust EOS protection for USB PD power rails and industrial load switch inputs.
For engineers reviewing the JANTXV1N5552 datasheet, pinout, applications, or equivalent options, key selection criteria include its constant-clamp behavior under high IPP, low leakage (<600nA at 22V), 175pF junction capacitance, DFN 1.6×1.6mm package with 6-pin symmetric I/O/GND layout, and compliance with MIL-PRF-19500/562 requirements for space-qualified surge protection.
Technical Context
JANTXV1N5552 implements a transient diverting architecture using a surge-rated FET as the primary shunt element, activated by a precision trigger circuit that fires when input voltage exceeds 25–27.9V breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly flat (27.5–28V) from 24A to 40A peak pulse current due to decreasing RDS(on) under surge stress.
The device operates across -55°C to +150°C junction temperature, supports ±1kV IEC 61000-4-5 unsymmetrical line surges (1.2/50μs voltage, 8/20μs current, RS=42Ω), and achieves ±4kV EFT immunity per IEC 61000-4-4 - all while maintaining <600nA reverse leakage at VRWM=22V and 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage before activation; matches USB PD 20V nominal + margin. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures protected ICs (e.g., load switches, PD controllers) remain below absolute max ratings during worst-case surge. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity without derating at full temperature range. |
| Dynamic Resistance | 20mΩ - enables flat clamping curve; reduces voltage overshoot vs. TVS diodes whose VC rises linearly with IPP. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for USB PD VBUS protection without signal integrity impact on power lines. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD immunity requirements for front-end connectors. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path; all three must be connected to minimize parasitic inductance during 40A surge discharge. |
| Pins 4, 5, 6 | IN | Protected line input (VBUS, power rail); parallel connection ensures current sharing and maximizes IPP handling capability. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V across 24–40A IPP range - eliminates need for over-spec'ing IPP to meet VC budget. |
| Temperature-stable protection | VC remains 27.5–28V from -40°C to +125°C - removes thermal derating uncertainty in industrial/automotive environments. |
| Low dynamic resistance | 20mΩ enables efficient energy diversion with minimal self-heating during multi-pulse surge events. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) supports repeated lightning-induced transients in remote metering and robotics. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20V USB PD power rails against connector ESD and hot-plug surges in notebooks and docking stations. IC Role / Device Role / Timing Role: Transient diverting suppressor placed directly at Type-C receptacle VBUS pin to clamp surges before reaching PD controller and load switch. Use Value: Maintains 27.5V clamping at 40A ensures PD controller ICs (e.g., FUSB302, TUSB7320) stay within 30V absolute max rating even at 125°C ambient. |
Use Scenario: Safeguarding enable and input pins of industrial-grade load switches (e.g., TPS229xx, NIS513x) against lightning-induced surges in remote meters and PLC I/O modules. IC Role / Device Role / Timing Role: Front-end EOS protector on VIN and EN lines to prevent gate oxide damage and latch-up in integrated FETs. Use Value: 20mΩ dynamic resistance limits voltage overshoot during fast-rising surges, preventing premature failure of internal switch FETs under repeated 1.2/50μs transients. |
| IoT Edge Node Power Bus Protection | Storage Device 12–24V Rail Protection |
Use Scenario: Securing 22V auxiliary power rails in battery-backed IoT gateways exposed to ESD during field maintenance or environmental EOS. IC Role / Device Role / Timing Role: Single-device solution for DC bus protection replacing multi-component TVS+MOV stacks in space-constrained edge nodes. Use Value: 1.6×1.6mm DFN footprint saves >60% board area vs. discrete TVS + series resistor solutions while delivering superior clamping consistency. |
Use Scenario: Protecting SATA/M.2 NVMe storage module 12V/19V/24V power inputs from surges induced by hot-swap events or shared chassis grounding. IC Role / Device Role / Timing Role: Primary surge diverter on main power input to SSD controller and PMIC, coordinated with low-capacitance TVS on data lanes. Use Value: 175pF capacitance avoids resonance with bulk input capacitors, eliminating risk of ringing-induced overvoltage on downstream regulators. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Semtech TDS2211P | Same functional architecture, identical 22V VRWM, 27.5–28V clamping, and 40A IPP rating; DFN 1.6×1.6mm package with identical 6-pin GND/IN layout. | Commercial-grade AEC-Q200 qualified part; lacks MIL-PRF-19500 screening but offers same electrical performance and footprint. | Select for cost-sensitive industrial or consumer designs where extended temperature screening is not required. |
| Littelfuse SP3022-01UTG | TVS diode (not TDS architecture); higher clamping (33V at 24A), greater VC drift with temperature (+15% from -40°C to +125°C), 25pF capacitance. | Better suited for low-capacitance data-line protection; less effective for high-current power rail clamping where flat VC is critical. | Select only if board space allows larger SOD-323 package and design can tolerate higher/temperature-variable clamping. |
Compared with JANTXV1N5552, TDS2211P provides identical protection performance in commercial grade, while SP3022-01UTG trades clamping stability for lower capacitance - making JANTXV1N5552 optimal for high-reliability 22V power rail protection where VC consistency across temperature and current is mandatory.

FAQ
What is the maximum continuous operating voltage for JANTXV1N5552?
JANTXV1N5552 has a reverse stand-off voltage (VRWM) of 22V, meaning it remains non-conductive up to this DC voltage level under normal operation. This rating aligns precisely with USB PD 20V nominal bus plus safety margin, ensuring no leakage or conduction during steady-state conditions while providing immediate response above threshold.
How does JANTXV1N5552 differ from standard TVS diodes in surge clamping behavior?
JANTXV1N5552 uses a transient diverting architecture with a surge-rated FET and precision trigger circuit, resulting in near-constant clamping voltage (27.5–28V) across its full 24–40A peak pulse current range. In contrast, standard TVS diodes exhibit linear VC rise with IPP due to fixed dynamic resistance - a key differentiator confirmed in Semtech's comparative clamping curves.
Is JANTXV1N5552 compatible with automated SMT assembly processes?
Yes, JANTXV1N5552 is supplied in tape-and-reel format (3,000 units per 7-inch reel) and features a standard DFN 1.6×1.6mm package with exposed thermal pad-compatible footprint. Its Pb-free, RoHS-compliant lead finish and UL 94V-0 molding compound support reflow profiles up to 260°C peak, meeting IPC-J-STD-020 moisture sensitivity level 1 requirements.
What is the junction capacitance of JANTXV1N5552 and why does it matter for power rail protection?
JANTXV1N5552 exhibits 175pF junction capacitance at 22V and 1MHz. This value is intentionally balanced: low enough to avoid resonance with typical 10–100μF input bulk capacitors on 22V rails, yet high enough to sustain robust 40A surge current without excessive voltage overshoot - a design trade-off validated in its application notes for USB PD and load switch protection.
Does JANTXV1N5552 require external components to function as a complete surge protection solution?
No, JANTXV1N5552 operates as a fully self-contained transient diverter - requiring no series impedance, RC networks, or biasing. Its integrated trigger circuit activates automatically above 25–27.9V breakdown, and the shunt FET conducts surge current directly to ground via Pins 1–3. Layout best practice mandates direct, low-inductance connections to both IN (Pins 4–6) and GND (Pins 1–3), as specified in the official datasheet.
