Product details
Overview
JANS1N4101D-1/TR from Microsemi is a 500 mW, 8.2 V ±1% tolerance, metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded 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 200 Ω dynamic impedance, low noise density (1 µV/√Hz), and operates across –65 °C to +175 °C junction temperature.
For engineers reviewing the JANS1N4101D-1/TR datasheet, JANS1N4101D-1/TR pinout, JANS1N4101D-1/TR application, or JANS1N4101D-1/TR equivalent, key selection criteria include Zener voltage tolerance (1%), radiation hardness, hermetic glass packaging, thermal resistance (250 °C/W junction-to-lead), and MIL-qualified reliability level - all critical for precision reference and power conditioning in harsh-environment systems.
Technical Context
This device functions as a two-terminal reverse-biased voltage reference, operating in Zener breakdown mode with a nominal 8.2 V regulation at 250 mA. Its internal metallurgical bond ensures mechanical robustness and long-term stability under thermal cycling and vibration stress typical of space-grade deployments.
It exhibits a positive temperature coefficient of +0.070 %/°C and maximum reverse leakage of 0.5 µA at 6.3 V, enabling predictable drift compensation in analog reference chains. Noise density is specified at 1 µV/√Hz, supporting low-noise instrumentation and ADC reference buffering where spectral purity matters.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4101D-1 | Same electrical specs and DO-35 package, but qualified only to JANTXV level (not JANS); lacks full space-level screening and radiation report documentation. | Approved for military airborne platforms but not certified for launch-vehicle or spacecraft use per MIL-STD-883 Class B requirements. | Select when cost sensitivity outweighs need for full JANS traceability and radiation assurance. |
| 1N4101DUR-1 | Surface-mount DO-213AA variant; identical 8.2 V ±1% Zener spec and noise performance, but no JANS qualification; RoHS-compliant matte-tin plating. | Used in commercial or industrial PCBs where automated assembly and smaller footprint are prioritized over hermeticity and radiation tolerance. | Choose for volume production where reflow compatibility and board space savings justify trade-off in reliability assurance. |
Compared with JANTXV1N4101D-1, the JANS1N4101D-1/TR adds full space-qualification traceability and radiation hardness validation; versus 1N4101DUR-1, it trades SMT convenience for hermetic axial-leaded ruggedness and MIL-spec screening - making it the sole choice for flight-critical voltage references.
