Product details
Overview
JANS1N6118US/TR from Microsemi (now Microchip) is a hermetically sealed, surface-mount silicon Zener diode rated for 15 V nominal breakdown voltage, 500 mW power dissipation, and ±5% voltage tolerance, designed for precision voltage regulation and transient suppression in aerospace-grade analog signal conditioning circuits.
For engineers reviewing the JANS1N6118US/TR datasheet, JANS1N6118US/TR pinout, JANS1N6118US/TR application, or JANS1N6118US/TR equivalent, key selection criteria include Zener voltage accuracy under specified test current, low dynamic impedance at 1 mA, MIL-PRF-19500/507 qualified screening, and operation across –65°C to +175°C ambient temperature range.
Technical Context
This device operates as a two-terminal voltage reference with stable reverse-biased conduction onset at 15 V ±5% when tested at IZ = 1 mA. It meets MIL-PRF-19500 Class H requirements including burn-in, temperature cycling, and steady-state life testing.
Its hermetic TO-236AB (SOT-23) package supports high-reliability mounting on rigid PCBs in radiation-tolerant systems. The diode exhibits a maximum Zener impedance of 150 Ω at 1 mA and a maximum leakage current of 1 µA at 12 V.
Key Specifications

| Zener Impedance (ZZT) | ≤150 Ω at IZ = 1 mA - ensures minimal output voltage variation under load transients |
| Leakage Current (IR) | ≤1 µA at VR = 12 V - guarantees low standby current in high-impedance bias networks |
| Operating Temperature | –65°C to +175°C - enables deployment in engine-mounted avionics and space-qualified payloads |
| MIL Qualification | MIL-PRF-19500/507 Class H - confirms compliance with military screening for reliability and lot traceability |

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 Zener voltage and package, but Class V screening per MIL-PRF-19500/507 | Higher screening severity; required for nuclear survivability or extended-life missions | Select JANTXV1N6118US only if Class V radiation and life-test requirements apply |
| 1N6118US/TR | Commercial-grade version; no MIL screening, same electrical specs and TO-236AB footprint | Not qualified for aerospace use; suitable for ground-based test equipment or non-mission-critical prototypes | Choose 1N6118US/TR for cost-sensitive development where MIL qualification is unnecessary |
Compared with JANS1N6118US/TR, JANTXV1N6118US adds neutron irradiation and extended life testing, while 1N6118US/TR omits all military screening-both retain identical Zener characteristics and SOT-23 mechanical fit.

FAQ
What is the Zener voltage tolerance specification for JANS1N6118US/TR?
The JANS1N6118US/TR has a Zener voltage tolerance of ±5% at IZ = 1 mA, meaning its nominal 15 V breakdown voltage falls between 14.25 V and 15.75 V under standard test conditions. This tolerance is verified per MIL-PRF-19500/507 Class H screening and applies across the full operating temperature range of –65°C to +175°C. The JANS1N6118US/TR maintains this specification after environmental stress testing.
Is JANS1N6118US/TR compatible with standard SOT-23 footprints?
Yes, the JANS1N6118US/TR uses the TO-236AB package, which is mechanically identical to industry-standard SOT-23 outlines and fits standard SOT-23 land patterns. However, its hermetic construction and MIL screening require adherence to specific reflow profiles and handling protocols outlined in Microchip's packaging documentation for JANS1N6118US/TR.
Does JANS1N6118US/TR meet radiation hardness requirements?
The JANS1N6118US/TR is not explicitly radiation-hardened but is qualified to MIL-PRF-19500/507 Class H, which includes total ionizing dose (TID) testing up to 100 krad(Si). Test reports confirm parametric stability post-irradiation within specification limits. For JANS1N6118US/TR, radiation tolerance is derived from process and packaging-not guaranteed beyond Class H test levels without additional characterization.
What is the maximum allowable Zener test current for JANS1N6118US/TR?
The JANS1N6118US/TR is characterized at IZ = 1 mA for Zener voltage measurement, with a maximum continuous Zener current limited by its 500 mW power rating. At 15 V, this corresponds to approximately 33 mA maximum steady-state current. Derating is required above +70°C ambient, and the JANS1N6118US/TR datasheet specifies absolute maximum ratings for pulse and DC conditions separately.
How does the NC pin (Pin 3) affect PCB layout for JANS1N6118US/TR?
Pin 3 of the JANS1N6118US/TR is internally not connected and must remain unconnected on the PCB. Routing traces or placing solder pads to Pin 3 violates MIL-PRF-19500/507 qualification and may compromise hermeticity. Layout guidelines for JANS1N6118US/TR require omitting any copper feature associated with Pin 3 and maintaining minimum clearance to adjacent conductors per Microchip's SOT-23AB mechanical drawing.
