Product details
Overview
JANTX1N6118US/TR from Microsemi (now Microchip) is a military-grade 150 V, 500 mW silicon Zener diode in a hermetically sealed DO-213AA (GLASS) package, with ±5% tolerance and 100 µA maximum leakage current at rated voltage, used for precision voltage regulation and overvoltage protection in avionics power supplies.
For engineers reviewing the JANTX1N6118US/TR datasheet, JANTX1N6118US/TR pinout, JANTX1N6118US/TR application, or JANTX1N6118US/TR equivalent, key selection criteria include Zener voltage accuracy, low leakage under bias, hermetic sealing for reliability in harsh environments, and compliance with MIL-PRF-19500/427.
Technical Context
This device operates as a two-terminal voltage reference diode, exhibiting sharp reverse-breakdown characteristics at 150 V nominal. Its design meets Class S screening per MIL-PRF-19500/427, including temperature cycling, burn-in, and lot acceptance testing.
The DO-213AA glass package provides hermeticity and thermal stability, supporting operation from –65°C to +175°C. The device is unidirectional and intended for DC voltage clamping or regulation only-no transient suppression rating or surge capability is specified.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 150 V ±5% - defines stable regulation point under reverse bias at IZ = 1.0 mA |
| Power Dissipation (PZ) | 500 mW - maximum continuous DC power handling in free-air at TA = 25°C |
| Zener Impedance (ZZT) | 1.2 kΩ max at IZ = 1.0 mA - limits regulation error under load variation |
| Reverse Leakage (IR) | 100 µA max at VR = 120 V - ensures minimal parasitic current in standby regulation |
| Operating Temp Range | –65°C to +175°C - enables use in extended-temperature military and aerospace systems |
| Package | DO-213AA (Glass, Hermetic) - provides moisture-free, high-reliability enclosure per MIL-STD-750 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6118US | Same electrical specs but non-tray packaging (bulk); no tape-and-reel delivery option | Preferred for manual prototyping or low-volume repair; lacks TR designation for automated placement | Select JANTX1N6118US/TR when SMT assembly line compatibility and traceable reel sourcing are required |
| 1N6118US-1 | Commercial-grade version (JAN not applied); no MIL-PRF-19500 screening or extended temp validation | Suitable for ground-based test equipment where radiation hardness and -65°C start-up not needed | Choose JANTX1N6118US/TR only when Class S reliability and hermeticity are mandated by system spec |
Compared with JANTXV1N6118US and 1N6118US-1, the JANTX1N6118US/TR uniquely combines tape-and-reel delivery, full MIL-PRF-19500/427 Class S qualification, and hermetic DO-213AA packaging-making it the sole option for high-reliability SMT production in defense flight hardware.

FAQ
What is the Zener voltage tolerance for JANTX1N6118US/TR?
The JANTX1N6118US/TR has a Zener voltage tolerance of ±5% at 150 V nominal, measured at test current IZ = 1.0 mA. This tolerance is verified per MIL-PRF-19500/427 Class S screening and applies across the full operating temperature range of –65°C to +175°C. The JANTX1N6118US/TR maintains this specification without derating in hermetic glass packaging.
Is JANTX1N6118US/TR suitable for surface-mount assembly?
Yes, the JANTX1N6118US/TR is supplied in tape-and-reel format (TR suffix) compatible with standard SMT pick-and-place equipment. Its DO-213AA package has axial leads formed for gull-wing or inline placement, and the reel packaging meets EIA-481 standards. The JANTX1N6118US/TR is qualified for reflow profiles up to 260°C peak per MIL-STD-750 Method 2035.
Does JANTX1N6118US/TR have surge or transient voltage suppression capability?
No, the JANTX1N6118US/TR is not rated for surge or transient suppression. It is a precision Zener diode designed for DC voltage regulation and clamping only. The JANTX1N6118US/TR does not specify peak pulse power, clamping voltage under fast transients, or response time-parameters required for TVS or MOV devices. Use dedicated transient suppressors for surge events.
What is the maximum reverse leakage current for JANTX1N6118US/TR?
The maximum reverse leakage current for JANTX1N6118US/TR is 100 µA at VR = 120 V and TA = 25°C, as defined in MIL-PRF-19500/427. This value is confirmed after burn-in and is guaranteed for all units in Class S lots. The JANTX1N6118US/TR exhibits lower leakage (<10 µA) at VR = 100 V, supporting low-power standby modes.
How does JANTX1N6118US/TR differ from commercial 1N6118 variants?
The JANTX1N6118US/TR differs from commercial 1N6118 variants in three key ways: it undergoes full MIL-PRF-19500/427 Class S screening (including temperature cycling and lot acceptance tests), uses a hermetic DO-213AA glass package instead of plastic, and guarantees operation from –65°C to +175°C. The JANTX1N6118US/TR also carries traceable reel packaging and QPL listing-features absent in commercial versions.
