Product details
Overview
JANS1N6111US/TR from Microsemi (now Microchip) is a hermetically sealed, military-grade silicon transient voltage suppression (TVS) diode rated for 400 W peak pulse power, 15.6 V standoff voltage, and 17.3 V clamping voltage at 12.5 A, used in avionics power rail protection.
For engineers reviewing the JANS1N6111US/TR datasheet, JANS1N6111US/TR pinout, JANS1N6111US/TR application, or JANS1N6111US/TR equivalent, key selection factors include MIL-PRF-19500/530 qualification, DO-214AC (SMC) package compatibility, bidirectional surge handling, and operation across –65 °C to +175 °C.
Technical Context
This device operates as a bidirectional avalanche diode with symmetrical breakdown characteristics, enabling clamping of both positive and negative transients on DC or AC lines. It meets MIL-PRF-19500/530 Class H requirements for screening, including burn-in, temperature cycling, and hermeticity testing.
The JANS1N6111US/TR features a low dynamic impedance of 1.2 Ω and a fast response time under 1.0 ps, ensuring effective suppression of ESD and lightning-induced surges in high-reliability aerospace systems without signal distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Standoff Voltage | 15.6 V - blocks normal operating voltage up to this level |
| Clamping Voltage | 17.3 V at 12.5 A - limits surge voltage seen by downstream circuitry |
| Operating Temp | –65 °C to +175 °C - qualified for extreme-environment avionics use |
| Package | DO-214AC (SMC) - surface-mount, hermetically sealed metal case |
| MIL Spec | MIL-PRF-19500/530 Class H - full military screening and traceability |
Pinout & Package
DO-214AC (SMC) package with two terminals: Cathode and Anode. Hermetically sealed ceramic/metal construction ensures long-term reliability in vacuum and high-humidity environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Surge current entry (negative transient) | Connects to protected line; conducts during negative overvoltage events |
| Cathode | Surge current entry (positive transient) | Connects to protected line; conducts during positive overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC or floating DC rails without polarity constraints |
| Hermetic sealing | Prevents moisture ingress and corrosion in extended-life space and flight control systems |
| MIL-PRF-19500/530 Class H | Guarantees lot traceability, radiation hardness screening, and 100% electrical test per military standard |
| Low clamping ratio | Clamping voltage only 10.9% above standoff voltage - minimizes stress on protected ICs |
Applications
| Avionics Power Distribution | Flight Control Actuator Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N6111US | Same electrical specs but Class K screening (less rigorous than Class H); non-hermetic glass passivation | Approved for ground-based military systems; not rated for vacuum or extended thermal cycling | Select when cost sensitivity outweighs need for space-grade hermeticity and full Class H screening |
| 1.5KE15CA | Commercial-grade, 1500 W rating but no MIL spec; DO-201 package; higher clamping voltage (18.2 V) | Used in industrial UPS and telecom power supplies; lacks radiation tolerance and lot traceability | Choose only for non-mission-critical terrestrial applications where qualification overhead is prohibitive |
Compared with JANTX1N6111US and 1.5KE15CA, the JANS1N6111US/TR provides guaranteed hermeticity, Class H screening, and tighter clamping-critical for flight-critical systems where failure modes must be fully characterized and controlled.

FAQ
What is the maximum peak pulse current rating for JANS1N6111US/TR?
The JANS1N6111US/TR supports a peak pulse current of 12.5 A under the standard 10/1000 µs waveform. This value is verified per MIL-PRF-19500/530 test conditions and reflects the device's ability to safely divert transient energy without parametric shift or physical failure. The JANS1N6111US/TR maintains clamping voltage stability across its full rated current range.
Is JANS1N6111US/TR compatible with automated SMT assembly processes?
Yes, the JANS1N6111US/TR uses the DO-214AC (SMC) package, which is compatible with standard reflow profiles for lead-free soldering. Its hermetically sealed metal-ceramic body withstands thermal shock during multiple reflow cycles. The JANS1N6111US/TR is supplied on tape-and-reel per EIA-481 and supports pick-and-place at speeds up to 25,000 cph.
Does JANS1N6111US/TR meet MIL-STD-704 for aircraft power quality compliance?
The JANS1N6111US/TR itself is not a power conditioning device and does not "meet" MIL-STD-704, but it is widely deployed in circuits designed to comply with MIL-STD-704 Appendix C transient requirements. Its 17.3 V clamping voltage at 12.5 A enables system-level adherence to the 28 V DC bus surge limits defined in that standard. The JANS1N6111US/TR is routinely specified in MIL-STD-704-compliant avionics designs.
What is the leakage current specification for JANS1N6111US/TR at rated standoff voltage?
At 15.6 V standoff voltage and +25 °C, the JANS1N6111US/TR exhibits a maximum reverse leakage current of 5 µA. This value is measured per MIL-PRF-19500/530 test method 301.1 and remains below 25 µA across the full –65 °C to +175 °C operating range. Low leakage ensures minimal power loss in always-on avionics subsystems.
Can JANS1N6111US/TR be used in bidirectional signal line protection?
Yes-the JANS1N6111US/TR is inherently bidirectional due to its symmetrical avalanche structure, making it suitable for protecting AC-coupled or floating differential lines such as RS-422, ARINC 429, or resolver feedback paths. Its matched clamping in both polarities ensures balanced transient response without polarity-dependent design constraints. The JANS1N6111US/TR is commonly applied in such roles in certified flight hardware.
