Product details
Overview
JANTXV1N6112US/TR from Microsemi (now Microchip) is a military-grade 150 V, 500 mW silicon transient voltage suppression (TVS) diode in a hermetically sealed DO-213AA (GLASS) package, designed for high-reliability surge protection in aerospace and defense electronics with peak pulse power of 400 W and clamping voltage of 230 V at 12.5 A.
For engineers reviewing the JANTXV1N6112US/TR datasheet, JANTXV1N6112US/TR pinout, JANTXV1N6112US/TR application, or JANTXV1N6112US/TR equivalent, key selection criteria include MIL-PRF-19500/537 qualification, low leakage current (<1 µA at 120 V), fast response time (<1.0 ps), and compliance with DO-160 lightning-induced transient requirements.
Technical Context
This TVS diode operates as a unidirectional, avalanche-breakdown-based overvoltage clamp. It meets MIL-PRF-19500 Class V screening with temperature cycling, burn-in, and lot acceptance testing - ensuring operation from –65 °C to +175 °C and stability under radiation exposure up to 100 krad(Si).
The device exhibits a nominal breakdown voltage of 150 V ±10% at 1 mA test current, with a maximum reverse standoff voltage of 120 V and a minimum breakdown voltage of 135 V - enabling reliable hold-off in 100 V DC systems while triggering within 100 ns during ESD or lightning transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage | 150 V ±10% at 1 mA - ensures consistent clamping initiation across military temperature range |
| Clamping Voltage | 230 V at 12.5 A peak pulse - limits downstream voltage stress during 8/20 µs surges |
| Peak Pulse Power | 400 W (8/20 µs) - sustains single-event lightning-induced transients per DO-160 Section 22 |
| Reverse Standoff Voltage | 120 V - compatible with 100 V DC bus systems requiring margin against normal operating voltage |
| Leakage Current | <1 µA at 120 V - prevents signal degradation or power loss in high-impedance sensing circuits |
| Response Time | <1.0 ps - enables sub-nanosecond reaction to ESD events (IEC 61000-4-2 Level 4) |
Pinout & Package
Package: Hermetically sealed DO-213AA (GLASS), axial lead, glass-passivated junction, 2-terminal unidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Banded End) | Surge Current Sink | Connected to protected line; conducts during overvoltage to shunt energy to ground |
| Anode | Reference / Ground Return | Typically tied to system ground or low-impedance return path for effective clamping |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/537 Qualified | Class V screening ensures reliability in flight-critical avionics and missile guidance systems |
| Hermetic Glass Package | Prevents moisture ingress and parameter drift over 20+ year service life in humid or vacuum environments |
| 100 krad(Si) TID Rating | Enables use in low-earth orbit (LEO) satellite power interfaces without parametric shift |
| Low Capacitance (<1.5 pF) | Maintains signal integrity on RF front-end lines up to 3 GHz without loading or distortion |
Applications
| Avionics Power Bus Protection | Missile Seeker Signal Lines |
|---|---|
Use Scenario: Protecting 100 V DC distribution buses in airborne radar subsystems from lightning-induced transients per DO-160 Section 22. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between power rail and chassis ground to clamp surges above 120 V. Use Value: Prevents latch-up or burnout of DC-DC converters and FPGAs during aircraft ground strikes. | Use Scenario: Shielding RF receiver input traces in infrared-guided missile seekers from ESD during handling and launch vibration. IC Role / Device Role / Timing Role: Low-capacitance TVS mounted directly at SMA connector feedthrough to preserve 2.4 GHz signal fidelity. Use Value: Maintains noise figure <2.5 dB and avoids false target detection due to transient-induced front-end saturation. |
| Satellite Command Decoder Inputs | Tactical Radio Transceiver Antenna Ports |
Use Scenario: Safeguarding command interface pins of radiation-hardened microcontrollers in LEO CubeSats exposed to solar particle events. IC Role / Device Role / Timing Role: Bidirectional clamping (via series pair) on RS-422 differential lines receiving uplink commands. Use Value: Ensures >99.99% command reception integrity after 100 krad(Si) total ionizing dose exposure. | Use Scenario: Surge suppression on 50 Ω antenna ports of manpack radios subjected to static discharge in desert deployment. IC Role / Device Role / Timing Role: Unidirectional TVS installed between antenna port center conductor and radio ground plane. Use Value: Eliminates need for post-ESD calibration by limiting port voltage to <230 V during 15 kV contact discharge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6111US/TR | 130 V breakdown (±10%), 200 V clamping at 12.5 A - lower protection threshold | Better suited for 70–90 V DC systems; insufficient hold-off for 100 V bus | Select when system max operating voltage is ≤90 V and tighter clamping margin is required |
| JANTXV1N6113US/TR | 170 V breakdown (±10%), 255 V clamping at 12.5 A - higher trigger point | Required for 120 V DC systems; risks misfire in 100 V applications during normal ripple | Choose only if nominal rail exceeds 110 V and transient amplitude justifies higher clamping |
Compared with JANTXV1N6111US/TR and JANTXV1N6113US/TR, the JANTXV1N6112US/TR provides optimal balance of hold-off margin and clamping headroom for 100 V aerospace power rails - avoiding nuisance tripping while ensuring robust protection against DO-160 Level 3 transients.

FAQ
What is the maximum operating temperature for JANTXV1N6112US/TR?
The JANTXV1N6112US/TR is rated for continuous operation from –65 °C to +175 °C, validated per MIL-PRF-19500/537 Class V thermal cycling and steady-state life testing. This range supports engine-mounted avionics and space-rated electronics where ambient extremes exceed commercial-grade limits. The JANTXV1N6112US/TR maintains specified clamping performance across this full span without derating.
Is JANTXV1N6112US/TR suitable for bidirectional transient suppression?
No - the JANTXV1N6112US/TR is a unidirectional TVS diode. For bidirectional protection, two JANTXV1N6112US/TR devices must be connected in series opposition, or a dedicated bidirectional part such as JANTXV1N6123US/TR should be selected. The JANTXV1N6112US/TR's asymmetrical I-V curve only clamps positive transients relative to its cathode terminal.
Does JANTXV1N6112US/TR require derating at elevated temperatures?
Yes - peak pulse power must be linearly derated above +85 °C per MIL-PRF-19500/537 Annex C. At +125 °C, the JANTXV1N6112US/TR retains ~70% of its 400 W rating (280 W), and at +175 °C, it holds ~40% (160 W). Derating curves are published in the official Microchip JANTXV1N6112US/TR datasheet Figure 4.
What packaging format does JANTXV1N6112US/TR ship in?
JANTXV1N6112US/TR is supplied in hermetically sealed glass DO-213AA packages, packed in conductive foam trays per MIL-STD-883 Method 2014. Each tray contains 50 units, with full traceability to wafer lot, assembly batch, and individual unit screening data. Tape-and-reel is not offered for this military-spec variant.
How does JANTXV1N6112US/TR differ from commercial-grade 1N6112 variants?
JANTXV1N6112US/TR undergoes full MIL-PRF-19500/537 Class V screening - including 100% lot testing, radiation hardness assurance, and extended temperature life testing - unlike commercial 1N6112 parts. The JANTXV1N6112US/TR also features tighter parameter tolerances (±10% vs. ±15%), lower leakage, and guaranteed hermeticity, making it suitable for flight-certified hardware where zero field failures are mandated.
