Product details
Overview
JAN1N4101D-1/TR from Microsemi is a 500 mW, 8.2 V Zener diode in DO-35 glass package with 1% voltage tolerance, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense power regulation applications.
For engineers reviewing the JAN1N4101D-1/TR datasheet, JAN1N4101D-1/TR pinout, JAN1N4101D-1/TR application, or JAN1N4101D-1/TR equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (1 µV/√Hz), JANS-level radiation hardness, and hermetic DO-35 packaging for extreme-environment stability.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, maintaining stable 8.2 V output across current range 0.5–6.3 mA at 25 °C. Its metallurgically bonded junction ensures low dynamic impedance (200 Ω at IZT = 250 µA) and minimal capacitance (typ. 40 pF).
Designed for high-reliability mil-aero systems, it delivers temperature-stable regulation with +0.070 %/°C coefficient and supports full derating from 500 mW at 25 °C to zero at 175 °C ambient, meeting stringent thermal and radiation requirements per MicroNote 050.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4101US-1 | Same 8.2 V, 1% spec, but in DO-213AA surface-mount package; RθJA = 400 °C/W vs. 300 °C/W for DO-35. | Requires rework of through-hole layout; better suited for high-density PCBs where axial leads are impractical. | Select when board space constraints prohibit axial components and thermal management allows higher junction rise. |
| JANTXV1N4101D-1 | Identical electrical specs and DO-35 package, but qualified to JANTXV level (not JANS); lacks full radiation hardness validation. | Approved for high-reliability ground systems and non-orbiting platforms where full JANS screening is not mandated. | Select when cost sensitivity outweighs space radiation requirements and MIL-PRF-19500/435 Level 3 compliance suffices. |
Compared with JAN1N4101D-1/TR, 1N4101US-1 trades axial-mount ruggedness for SMT compatibility and reduced footprint, while JANTXV1N4101D-1 retains identical form-factor but reduces qualification scope-enabling cost optimization where full JANS radiation assurance is unnecessary.

FAQ
What is the Zener voltage tolerance and test current for JAN1N4101D-1/TR?
JAN1N4101D-1/TR has a nominal Zener voltage of 8.2 V with ±1% tolerance, measured at a Zener test current (IZT) of 250 µA. This tight tolerance is achieved via post-process binning and verified during JANS qualification screening, making JAN1N4101D-1/TR suitable for applications demanding high initial accuracy without external trimming.
Is JAN1N4101D-1/TR RoHS compliant?
No, JAN1N4101D-1/TR is not RoHS compliant. The "e3" RoHS suffix is only available on commercial-grade versions (e.g., 1N4101D-1e3); JAN-level parts like JAN1N4101D-1/TR use traditional tin-lead plating per MIL-STD-750 and are exempt from RoHS due to their military/aerospace qualification status and reliability requirements.
What is the maximum power dissipation and thermal derating behavior of JAN1N4101D-1/TR?
JAN1N4101D-1/TR is rated for 500 mW average power dissipation at case temperature (TC) = 25 °C, with linear derating beginning at 50 °C and reaching zero at 175 °C. On a typical FR4 board, it derates from 500 mW starting at 25 °C ambient, enabling safe operation up to 175 °C junction temperature-critical for sealed avionics enclosures.
How does the noise performance of JAN1N4101D-1/TR compare to lower-voltage Zeners in the same family?
JAN1N4101D-1/TR exhibits 1 µV/√Hz noise density at 250 µA, consistent with other mid-voltage Zeners (6.8–10 V) in the 1N4099–1N4135 series. This is significantly lower than sub-3 V devices (e.g., 1N4614-1 at 1 µV/√Hz) and higher than >20 V parts (e.g., 1N4120-1 at 0.01 µV/√Hz), reflecting the inherent noise-voltage relationship in Zener structures.
What does the "D" in JAN1N4101D-1/TR signify in the part nomenclature?
The "D" in JAN1N4101D-1/TR indicates 1% Zener voltage tolerance per the Microsemi part numbering scheme. In the full nomenclature: JAN = reliability level, 1N4101 = JEDEC type number (8.2 V), D = ±1%, -1 = metallurgically bonded construction, TR = tape-and-reel packaging option per EIA-296 standard.
