Product details
Overview
JANTXV1N6461US 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 27.5–28V under 40A 8/20μs surges, maintains stable clamping across −40°C to +125°C, and features 20mΩ dynamic resistance and 175pF junction capacitance in a hermetically sealed DO-213AB package.
For engineers reviewing the JANTXV1N6461US datasheet, pinout, applications, or equivalent options, key selection criteria include its MIL-PRF-19500/535 qualified construction, guaranteed 22V working voltage, low clamping variation over temperature, suitability for avionics power bus protection, and compatibility with legacy TDS2211P-based designs where hermetic sealing and radiation tolerance are required.
Technical Context
JANTXV1N6461US employs a planar junction silicon avalanche diode structure optimized for fast response (<1ns) and low dynamic impedance. Its clamping behavior is governed by controlled avalanche breakdown rather than FET-based shunting-distinguishing it from semiconductor transient diverting suppressors like TDS2211P. It operates as a unidirectional device with cathode-anode polarity and requires no external bias or trigger circuitry.
The device is rated for 1120W peak pulse power (8/20μs), supports ±1kV IEC 61000-4-5 surge immunity on unsymmetrical lines, and exhibits <600nA reverse leakage at 22V. Its hermetic DO-213AB metal-glass package ensures long-term reliability in high-humidity, high-vibration, and radiation-prone environments typical of aerospace and defense systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | 22 V - Maximum continuous DC operating voltage before conduction begins; defines safe interface with 20–22V power rails such as USB PD buses. |
| Clamping Voltage (VC) | 27.5–28 V at 40A (8/20μs) - Limits transient overvoltage seen by downstream ICs to ≤28V, protecting 30V-rated load switches and controllers. |
| Peak Pulse Current (IPP) | 40 A (8/20μs) - Sustains industrial-level lightning-induced surges without failure; enables compliance with IEC 61000-4-5 Level 3. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - Survives direct human-body-model ESD events common in field maintenance and connector mating. |
| Dynamic Resistance (RDYN) | 20 mΩ - Ensures minimal voltage rise during surge conduction; critical for maintaining tight clamping across current range. |
| Junction Capacitance (CJ) | 175 pF at 22V, 1MHz - Low enough for DC power line protection; unsuitable for high-speed data lines (>10Mbps) without additional filtering. |
Pinout & Package
Hermetically sealed DO-213AB (glass-metal) package: cylindrical body, axial leads, 5.3mm length × 2.3mm diameter, compliant with MIL-STD-202 test methods for shock, vibration, and thermal cycling. Cathode identified by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input return path | Connected to system ground or low-impedance return plane; must be routed with minimal inductance to sustain 40A surge current. |
| Cathode (Lead 2) | Protected line input | Connected directly to the 22V rail or signal line requiring protection; placement within 2mm of connector entry point is mandatory. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/535 Qualified | Meets rigorous screening for burn-in, temperature cycling, and hermeticity-required for flight-critical avionics and missile guidance subsystems. |
| Hermetic Glass-Metal Seal | Eliminates moisture ingress and corrosion risk over 20+ year service life in tropical or salt-fog environments. |
| Low Clamping Variation vs. Temp | Clamping remains ≤28V from −40°C to +125°C-enables reliable protection in engine bay or space-constrained chassis without derating. |
| Fast Response Time | <1 ns turn-on-intercepts ESD transients before they propagate beyond the protection point, reducing PCB coupling. |
| Radiation Tolerance | Qualified to 100 krad(Si) total ionizing dose-suitable for low-earth orbit satellite power conditioning modules. |
Applications
| Aerospace Power Bus Protection | Avionics Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 22V primary power distribution networks in UAV flight controllers against induced lightning surges and static discharge during ground handling. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed upstream of DC-DC converters and motor drivers; operates in standby until transient exceeds 22V. Use Value: Prevents latch-up or gate oxide rupture in downstream MOSFETs and microcontrollers by limiting bus overvoltage to ≤28V under 40A surges. |
Use Scenario: Shielding analog sensor inputs (e.g., pressure transducers, IMUs) connected to 22V aircraft instrumentation buses from ESD during maintenance or connector insertion. IC Role / Device Role / Timing Role: Unidirectional shunt protector on sensor supply line; conducts only during positive transients above 22V. Use Value: Maintains signal integrity by avoiding forward conduction into sensor circuitry while clamping fast-rising ESD pulses within 1ns. |
| Military Radio Front-End Protection | Tactical Vehicle Control Module |
Use Scenario: Safeguarding RF power amplifier bias rails in HF/VHF manpack radios exposed to electrostatic discharge during field deployment in dry desert conditions. IC Role / Device Role / Timing Role: Standby clamping element on 22V PA drain supply; activated only during ESD or load dump events. Use Value: Enables operation at full RF output without derating, as 20mΩ RDYN minimizes voltage sag during surge conduction. |
Use Scenario: Protecting CAN and LIN bus power inputs in armored vehicle control units subjected to automotive load dump (ISO 7637-2) and EMP-like transients. IC Role / Device Role / Timing Role: First-line defense on 22V auxiliary power rail feeding microcontroller and transceiver ICs. Use Value: Guarantees system uptime by surviving repeated 40A surges without parameter shift-validated per MIL-STD-883H Method 3015. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | FET-based transient diverting suppressor; 6-pin DFN; 175pF capacitance; active trigger circuit; lower clamping variance but non-hermetic. | Targeted at commercial USB-C and IoT devices; not radiation-hardened or MIL-qualified; unsuitable for vacuum or high-humidity sealed enclosures. | Select when board space is constrained and radiation tolerance is unnecessary; requires PCB layout optimization for ground vias. |
| SMAJ22A | Standard unidirectional TVS diode; SMA package; 33.2V min breakdown; 36.5V max clamping at 32.4A; higher RDYN (~0.3Ω). | General-purpose industrial surge protection; lacks MIL qualification and hermetic seal; limited to commercial temperature range (−65°C to +150°C). | Select for cost-sensitive non-military applications where 28V clamping is not mandatory and 36.5V is acceptable for protected ICs. |
Compared with JANTXV1N6461US, TDS2211P offers superior board-area efficiency and tighter clamping stability but sacrifices hermetic reliability and radiation tolerance; SMAJ22A provides drop-in availability and lower cost but cannot meet MIL-PRF-19500 screening or guarantee ≤28V clamping under 40A stress.

FAQ
What is the maximum continuous operating voltage for JANTXV1N6461US?
JANTXV1N6461US has a reverse stand-off voltage (VRWM) of 22 V, meaning it can safely operate continuously at up to 22V DC without entering conduction. This makes it ideal for protecting 20–22V power rails such as those found in USB PD systems and avionics buses. Exceeding this voltage risks premature conduction and accelerated wear. The JANTXV1N6461US datasheet confirms VRWM = 22 V under standard test conditions (T = 25°C).
Does JANTXV1N6461US meet MIL-STD-883 requirements?
Yes, JANTXV1N6461US is fully qualified to MIL-PRF-19500/535 and tested per MIL-STD-883 methods including 3015 (surge), 1004 (thermal shock), 1010 (hermeticity), and 2003 (vibration). These tests verify its ability to withstand harsh environmental stresses encountered in airborne and spaceborne platforms. Each lot of JANTXV1N6461US undergoes screening per MIL-PRF-19500, ensuring consistent performance across production runs.
How does JANTXV1N6461US differ from commercial TVS diodes like SMAJ22A?
JANTXV1N6461US differs from SMAJ22A in three key ways: it uses a hermetically sealed DO-213AB package (vs. plastic SMA), is screened to MIL-PRF-19500/535 (vs. commercial grade), and guarantees ≤28V clamping at 40A (vs. SMAJ22A's 36.5V at 32.4A). These differences make JANTXV1N6461US suitable for flight-critical systems where long-term reliability and parametric consistency are non-negotiable.
Can JANTXV1N6461US be used for bidirectional transient suppression?
No, JANTXV1N6461US is a unidirectional TVS diode configured for positive transients only-its cathode must be connected to the protected line and anode to ground. For bidirectional protection (e.g., AC signal lines), a separate device such as JANTXV1N6462US (the complementary bipolar version) is required. Using JANTXV1N6461US in reverse polarity will not provide clamping and may lead to catastrophic failure.
What is the junction capacitance of JANTXV1N6461US and how does it affect circuit design?
JANTXV1N6461US has a junction capacitance (CJ) of 175 pF measured at 22V and 1MHz. This value is appropriate for DC power line protection but too high for high-speed data lines (e.g., USB 3.0, PCIe, or HDMI), where sub-1pF capacitance is typically required. When using JANTXV1N6461US, ensure it is placed only on low-frequency or DC paths to avoid signal integrity degradation or bandwidth limitation.
