Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4108C-1/TR | Same electrical specs but qualified to JANTXV level (lower screening rigor than JANS); no radiation hardness documentation | Approved for ground-based military systems without TID requirements; not cleared for spaceflight | Select when full JANS qualification is unnecessary and cost reduction is prioritized |
| 1N4108C-1/TR (commercial) | Identical Zener parameters but unqualified; RoHS-compliant plating only; no MIL-PRF-19500 compliance | Limited to non-critical industrial or test equipment; not suitable for safety-critical or mission-critical designs | Choose only for prototyping or commercial-grade applications where reliability certification is not required |

FAQ
What is the Zener voltage tolerance of JANS1N4108C-1/TR?
JANS1N4108C-1/TR has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This corresponds to a regulated voltage range of 13.72 V to 14.28 V at 250 mA test current and 25 °C ambient, verified per MIL-PRF-19500/435 screening.
Is JANS1N4108C-1/TR radiation hardened?
Yes, JANS1N4108C-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded glass construction and JANS-level qualification per MIL-PRF-19500/435 provide assurance for total ionizing dose (TID) resilience in space and nuclear environments-no additional shielding or derating is required for typical LEO missions.
What is the maximum power dissipation of JANS1N4108C-1/TR?
JANS1N4108C-1/TR has a rated average power dissipation of 500 mW at TC = 25 °C. It must be linearly derated starting at 50 °C lead temperature, reaching zero dissipation at 175 °C. On a standard FR4 board with 4 mm² copper pads, this translates to ~350 mW usable power at 85 °C ambient.
Does JANS1N4108C-1/TR have low noise characteristics?
Yes, JANS1N4108C-1/TR exhibits a noise density of 1 µV/√Hz at 14.0 V and 250 mA, measured in the 1 kHz–3 kHz band. This low broadband noise supports use in precision analog circuits such as ADC references and low-phase-noise oscillator bias networks where signal integrity is critical.
What package type does JANS1N4108C-1/TR use?
JANS1N4108C-1/TR uses the DO-35 (DO-204AH) axial-leaded glass package, with hermetically sealed construction, cathode identified by a band, and tin-lead plated leads compliant with MIL-STD-750 method 2026. The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard.
