Product details
Overview
JANTX1N6111US/TR from Microsemi (now Microchip) is a military-grade 500W transient voltage suppression (TVS) diode with a 170V standoff voltage, 190V breakdown voltage, and 2.6A peak pulse current rating in a hermetically sealed DO-213AA (GLASS) package; used for surge protection in avionics power rail interfaces.
For engineers reviewing the JANTX1N6111US/TR datasheet, JANTX1N6111US/TR pinout, JANTX1N6111US/TR application, or JANTX1N6111US/TR equivalent, key selection criteria include clamping voltage at specified peak current, MIL-PRF-19500/534 qualification, glass-body hermeticity, and unidirectional polarity for DC-biased protection circuits.
Technical Context
This unidirectional TVS diode operates as a fast-acting shunt clamp during ESD and lightning-induced transients, with a typical response time under 1.0 ps and clamping voltage of 274V at 2.6A IPP. It complies with MIL-PRF-19500/534 Class H screening and is rated for operation from –65°C to +175°C.
The device uses an avalanche breakdown mechanism and is designed for permanent mounting on printed wiring boards via axial leads; its glass passivation ensures stable leakage current (<1.0 µA at VRWM) and long-term reliability in high-vacuum or high-humidity environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6111US/TR | Higher screening level (Class V vs. Class H); includes additional radiation hardness testing per MIL-PRF-19500/534. | Required for nuclear-hardened or deep-space missions where total ionizing dose tolerance is critical. | Select JANTXV1N6111US/TR only when radiation hardness certification is mandated by program spec. |
| 1N6111US/TR | Commercial-grade version; no MIL screening, wider parametric tolerances (±10% VBR), and non-hermetic plastic package. | Suitable for non-mission-critical industrial controls where cost and availability outweigh environmental robustness. | Choose 1N6111US/TR for prototyping or non-aerospace production where MIL-qualified parts are not contractually required. |
Compared with JANTXV1N6111US/TR, the JANTX1N6111US/TR offers verified Class H reliability at lower cost and smaller test overhead; versus 1N6111US/TR, it delivers guaranteed hermeticity and tighter VBR tolerance essential for avionics deployment.

FAQ
What is the clamping voltage of the JANTX1N6111US/TR at its rated peak pulse current?
The JANTX1N6111US/TR has a maximum clamping voltage of 274 V when subjected to a 10/1000 µs waveform at its rated peak pulse current of 2.6 A. This value is measured per MIL-STD-750 Method 3017 and is guaranteed across the full operating temperature range of –65°C to +175°C. The JANTX1N6111US/TR maintains this clamping performance without derating in hermetically sealed operation.
Is the JANTX1N6111US/TR unidirectional or bidirectional?
The JANTX1N6111US/TR is a unidirectional TVS diode, indicated by its single cathode band and specified standoff/breakdown characteristics for reverse-biased operation only. It is not rated for symmetrical surge suppression and must be installed with correct polarity-cathode to ground-to function as intended. The JANTX1N6111US/TR datasheet explicitly defines parameters only for reverse conduction mode.
Does the JANTX1N6111US/TR meet MIL-PRF-19500 requirements?
Yes, the JANTX1N6111US/TR is fully compliant with MIL-PRF-19500/534 Class H, including all required screening tests: steady-state life, temperature cycling, burn-in, and fine-and-gross leak testing. This qualification is documented in Microchip's QML-38534 certified manufacturing flow, and the JANTX1N6111US/TR lot traceability supports full DSCC SMD traceability reporting.
What is the maximum operating temperature for the JANTX1N6111US/TR?
The JANTX1N6111US/TR is rated for continuous operation from –65°C to +175°C, validated per MIL-STD-202 Method 108. Its glass-body construction and internal metallization ensure no parameter shift or mechanical failure within this range. At +175°C, the JANTX1N6111US/TR maintains full clamping voltage specification and leakage current <5.0 µA, supporting engine bay and payload bay deployments.
Can the JANTX1N6111US/TR replace commercial 1N6111 devices in existing designs?
The JANTX1N6111US/TR shares identical electrical parameters and DO-213AA footprint with commercial 1N6111US/TR variants but adds MIL-PRF-19500/534 Class H screening and hermetic glass packaging. It can be substituted in existing layouts without modification, though design revalidation is recommended for mission-critical use due to tighter parametric limits and enhanced reliability testing of the JANTX1N6111US/TR.
