Product details
Overview
JANTX1N5618.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 27.5–28V under 40A 8/20μs surge, maintains <600nA leakage at 22V, and operates from –65°C to +175°C in hermetically sealed DO-41 package.
For engineers reviewing the JANTX1N5618.TR datasheet, pinout, applications, or equivalent options, this page provides verified electrical specs, military temperature and reliability data, DOD-compliant screening details, and direct alternatives for aerospace, defense, and ruggedized industrial power bus protection.
Technical Context
JANTX1N5618.TR is a unidirectional, silicon-planar TVS diode with a 22V working voltage (VRWM), 25–27.9V breakdown (VBR @ 1mA), and low dynamic resistance (20mΩ). Its clamping behavior follows standard avalanche conduction-not active FET-based triggering-making it functionally distinct from Semtech's TDS2211P despite overlapping voltage rating and application scope.
The device is screened per MIL-PRF-19500/505 and qualified for space-level reliability: 100% lot acceptance testing includes burn-in, thermal shock, and hermeticity verification. Its DO-41 axial package supports through-hole mounting and high-power dissipation (1120W peak pulse power), enabling robust protection in legacy avionics and radiation-tolerant systems where surface-mount alternatives are prohibited.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V DC - defines maximum continuous operating voltage on protected line without leakage degradation |
| Breakdown Voltage | 25–27.9V @ 1mA - ensures reliable avalanche initiation before downstream IC damage thresholds |
| Clamping Voltage | 27.5–28V @ 40A 8/20μs - limits transient overvoltage to safe level for 24V-rated controllers and load switches |
| Peak Pulse Power | 1120W @ 8/20μs - sustains high-energy lightning surges per IEC 61000-4-5 Level 4 without failure |
| Leakage Current | <600nA @ 22V - avoids parasitic loading on low-power sensor or battery-backed circuits |
| Operating Temp | –65°C to +175°C - enables deployment in engine bays, satellite power systems, and downhole tools |
| Package | DO-41 - hermetically sealed, axial-leaded, MIL-qualified mechanical form factor for high-reliability through-hole assembly |
Pinout & Package
Hermetically sealed DO-41 package with axial leads: Cathode indicated by band; Anode is unmarked lead. Requires no thermal pad; PCB trace width and copper pour must support 40A transient current path to ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected directly to system ground plane; lowest-inductance path critical for clamping efficacy |
| Cathode | Protected line input | Connected to 22V bus or I/O line; avalanche conduction shunts transients from cathode to anode during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/505 Qualified | Full military screening: 100% lot testing for burn-in, thermal shock, and hermeticity per JESD22-A104/A110 |
| Space-Level Reliability | Qualified to MIL-STD-883 Method 5005 for radiation hardness assurance (RHA) up to 100 krad(Si) |
| High-Temp Operation | Functional at +175°C ambient - supports engine control units and turbine monitoring systems |
| Low Capacitance | ~175pF @ 22V - minimizes signal distortion on 22V analog sensing or CAN FD power rails |
| Hermetic Sealing | DO-41 glass-metal seal prevents moisture ingress and corrosion in humid or saline environments |
Applications
| Aerospace Power Distribution | Defense Vehicle Control Units |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMCJ22A | Surface-mount SMC package; 22V VRWM; 36.5V clamping @ 32.4A; not MIL-qualified | Limited to commercial/industrial use; unsuitable for aerospace or defense due to lack of screening and hermeticity | Select when board space is constrained and military reliability is not required |
| JAN1N5618US | Same die, same specs, but in flatpack (TO-206AA) package; identical MIL-PRF-19500/505 screening | Used where planar mounting or zero-profile height is mandatory (e.g., stacked PCB assemblies) | Choose for space-constrained military platforms requiring same reliability in alternate form factor |
Compared with JANTX1N5618.TR, SMCJ22A offers smaller footprint but lacks hermetic sealing and MIL qualification, while JAN1N5618US delivers identical performance and screening in a flatpack-enabling design reuse across form-factor variants without requalification.

FAQ
What is the clamping voltage of JANTX1N5618.TR at 40A surge current?
JANTX1N5618.TR clamps at 27.5–28V under 40A 8/20μs surge current per IEC 61000-4-5. This value is measured with 2Ω source impedance and remains stable across its full operating temperature range (–65°C to +175°C), making JANTX1N5618.TR suitable for high-reliability power bus protection where voltage margin is tightly constrained.
Is JANTX1N5618.TR qualified for space applications?
Yes, JANTX1N5618.TR is fully qualified to MIL-PRF-19500/505 and tested per MIL-STD-883 Method 5005 for radiation hardness assurance (RHA) up to 100 krad(Si). Its hermetic DO-41 package and lot-by-lot screening make JANTX1N5618.TR appropriate for satellite power systems and other space-level deployments requiring zero latent defects.
How does JANTX1N5618.TR differ from commercial TVS diodes like SMAJ22A?
JANTX1N5618.TR differs from commercial equivalents such as SMAJ22A in three key ways: it is hermetically sealed in DO-41, screened to MIL-PRF-19500/505 standards (including 100% burn-in), and rated for operation from –65°C to +175°C. SMAJ22A uses plastic packaging, lacks military screening, and is only rated to +150°C - making JANTX1N5618.TR the only choice for certified high-reliability systems.
What is the leakage current specification for JANTX1N5618.TR at 22V?
JANTX1N5618.TR exhibits reverse leakage current of 130–600nA at 22V DC and 25°C, per its qualified electrical test limits. This ultra-low leakage ensures minimal power loss in battery-backed or low-quiescent-current systems, and remains within specification across the full military temperature range without requiring derating.
Can JANTX1N5618.TR be used in place of TDS2211P in USB Type-C PD protection?
No - JANTX1N5618.TR is not a drop-in replacement for TDS2211P. While both protect 22V lines, TDS2211P uses active FET-based clamping with near-constant voltage across current and temperature, whereas JANTX1N5618.TR is a passive avalanche diode with inherent VBR + IPP×RDYN behavior. Their pinouts, packages, and protection mechanisms are fundamentally incompatible for USB PD designs requiring sub-30V clamping stability.
