Product details
Overview
JANS1N4117C-1/TR from Microsemi is a 25 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications. It delivers stable voltage regulation at 250 mA test current with 150 Ω dynamic impedance, <0.01 µA reverse leakage at 19 V, and +0.090 %/°C temperature coefficient.
For engineers reviewing the JANS1N4117C-1/TR datasheet, JANS1N4117C-1/TR pinout, JANS1N4117C-1/TR application, or JANS1N4117C-1/TR equivalent, key selection criteria include Zener voltage tolerance (2%), radiation hardness, hermetic DO-35 packaging, MIL-qualified reliability level, and low-noise performance in precision reference circuits.
Technical Context
This device operates as a two-terminal shunt voltage regulator, biased in reverse breakdown with cathode band indicating polarity. Its metallurgical bond construction ensures mechanical robustness and thermal stability under shock/vibration, while its hermetically sealed DO-35 glass package maintains long-term parameter stability in harsh environments.
The JANS1N4117C-1/TR exhibits a positive temperature coefficient (+0.090 %/°C), enabling predictable drift compensation in temperature-critical references. Its 150 Ω dynamic impedance at 250 mA and <1 µV/√Hz noise density above 1 kHz support low-drift, low-noise analog signal conditioning and voltage reference design.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4117US-1 | Same 25 V, 2% spec but in surface-mount DO-213AA package; no JANS qualification | Lacks MIL-PRF-19500/435 screening; suitable only for commercial industrial PCBs with space constraints | Select when board area is limited and radiation/longevity requirements are relaxed |
| JANTXV1N4117C-1 | Identical electrical specs and DO-35 package, but qualified only to JANTXV level (not JANS) | Lower screening depth and no radiation hardness documentation; approved for military ground systems only | Select when full space-grade JANS compliance is not required but MIL-qualified reliability is still mandated |
Compared with JANS1N4117C-1/TR, the JANTXV1N4117C-1 offers identical regulation performance with reduced screening rigor, while the 1N4117US-1 trades hermeticity and reliability for SMT compatibility-neither is a drop-in replacement without requalification.

The JANS1N4117C-1/TR belongs to Microsemi's legacy MIL-PRF-19500/435 Zener diode family, engineered specifically for mission-critical voltage reference applications where parameter stability, hermetic sealing, and radiation tolerance are non-negotiable.
FAQ
What is the Zener voltage tolerance of JANS1N4117C-1/TR?
JANS1N4117C-1/TR has a nominal Zener voltage of 25.0 V with a tight ±2% tolerance, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This tolerance is guaranteed across the full operating temperature range of –65 °C to +175 °C under MIL-PRF-19500/435 JANS screening, making JANS1N4117C-1/TR suitable for precision reference designs where drift must remain bounded.
Is JANS1N4117C-1/TR radiation hardened?
Yes, JANS1N4117C-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded structure and hermetic DO-35 glass package provide natural tolerance to total ionizing dose (TID) without requiring additional shielding or derating-this characteristic is verified during JANS-level qualification per MIL-PRF-19500/435.
What does the "TR" suffix mean in JANS1N4117C-1/TR?
The "TR" suffix in JANS1N4117C-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. This format is standard for volume orders and does not affect electrical or reliability specifications; JANS1N4117C-1/TR retains full JANS qualification and DO-35 mechanical form factor regardless of packaging option.
Can JANS1N4117C-1/TR replace commercial-grade 1N4117 diodes in existing designs?
JANS1N4117C-1/TR shares identical electrical parameters and DO-35 footprint with commercial 1N4117 variants but adds JANS-level screening, hermeticity, and radiation tolerance. Substitution requires revalidation of thermal, mechanical, and radiation margins-JANS1N4117C-1/TR is not a plug-in replacement unless the original design already accounts for MIL-spec derating and traceability requirements.
What is the maximum reverse leakage current for JANS1N4117C-1/TR?
JANS1N4117C-1/TR specifies a maximum reverse leakage current (IR) of 0.01 µA at VR = 19.0 V, measured at 25 °C. This ultra-low leakage ensures negligible error current in high-impedance reference divider networks and supports long-term stability in battery-backed or low-power monitoring circuits using JANS1N4117C-1/TR.
