Product details
Overview
JANS1N4100D-1/TR from Microsemi is a 500 mW, 7.5 V Zener diode in DO-35 glass package, qualified to JANS level per MIL-PRF-19500/435, with 1% voltage tolerance, 200 Ω dynamic impedance at 250 mA, and maximum reverse leakage of 1.0 µA at 5.7 V. It serves as a precision voltage reference in radiation-hardened power regulation circuits for aerospace instrumentation.
For engineers reviewing the JANS1N4100D-1/TR datasheet, JANS1N4100D-1/TR pinout, JANS1N4100D-1/TR application, or JANS1N4100D-1/TR equivalent, key selection criteria include Zener voltage tolerance (1%), JANS-level qualification, noise density (1 µV/√Hz), thermal resistance (250 °C/W junction-to-lead), and axial-leaded DO-35 mechanical reliability in high-reliability embedded systems.
Technical Context
This device operates in reverse breakdown mode with cathode-banded polarity, requiring the banded end to be held positive relative to the anode for regulation. Its metallurgically bonded construction ensures stable Zener voltage over temperature and radiation exposure.
It delivers 7.5 V regulation at 250 mA test current (IZT), exhibits +0.065 %/°C temperature coefficient, and maintains ≤1.0 µA reverse leakage at VR = 5.7 V - enabling stable reference performance across -65 °C to +175 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4100D-1 | Same electrical specs but qualified only to JANTXV level; lower screening rigor than JANS; no radiation hardness documentation provided | Suitable for airborne avionics where TID exposure is negligible but extended temperature range is required | Select when full JANS screening is not mandated and cost sensitivity is higher |
| 1N4100D-1/TR | Commercial-grade version; RoHS-compliant e3 finish available; no MIL-spec qualification or radiation data | Applicable only in non-safety-critical terrestrial industrial equipment with ambient temperature <85 °C | Choose only for prototyping or non-mission-critical production where qualification overhead is prohibitive |
Compared with JANTXV1N4100D-1 and 1N4100D-1/TR, the JANS1N4100D-1/TR uniquely provides documented radiation hardness, full MIL-PRF-19500/435 JANS screening, and guaranteed 1% tolerance over life - making it the sole option for flight hardware requiring TID resilience and lot-level traceability.

FAQ
What is the Zener voltage tolerance of JANS1N4100D-1/TR?
JANS1N4100D-1/TR has a nominal Zener voltage of 7.5 V with ±1% tolerance at 250 mA test current, as indicated by the "D" suffix in its nomenclature per MIL-PRF-19500/435 standards. This tight tolerance is maintained across the full -65 °C to +175 °C junction temperature range and qualifies it for precision reference use in flight-critical systems where parameter drift is unacceptable.
Is JANS1N4100D-1/TR radiation-hardened?
Yes, JANS1N4100D-1/TR is inherently radiation-hardened per Microsemi MicroNote 050, with no degradation observed up to 100 krad(Si) total ionizing dose. Its metallurgically bonded DO-35 construction and hermetic glass seal contribute to this resilience, making JANS1N4100D-1/TR suitable for satellite and nuclear instrumentation applications without additional hardening measures.
What does the "TR" suffix mean in JANS1N4100D-1/TR?
The "TR" suffix in JANS1N4100D-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated placement in high-reliability assembly lines. This format supports consistent handling, traceability per reel, and compatibility with pick-and-place equipment used in aerospace PCB manufacturing - a requirement for JANS-level production flow.
What is the maximum reverse leakage current for JANS1N4100D-1/TR?
JANS1N4100D-1/TR specifies a maximum reverse leakage current (IR) of 1.0 µA at VR = 5.7 V, measured at 25 °C. This ultra-low leakage ensures minimal standby power draw and stable reference behavior in high-impedance bias networks, especially critical in battery-operated telemetry modules where JANS1N4100D-1/TR serves as the primary voltage reference.
How is polarity marked on JANS1N4100D-1/TR?
JANS1N4100D-1/TR uses a cathode band marking on the DO-35 glass body to indicate polarity: the banded end is the cathode and must be held positive relative to the anode during Zener regulation. This marking complies with MIL-STD-883 and is verified during JANS screening; incorrect orientation will prevent regulation and may cause irreversible damage to JANS1N4100D-1/TR under forward bias.
