Product details
Overview
JAN1N4102D-1 from Microsemi is a 500 mW, 8.7 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 JAN1N4102D-1 datasheet, JAN1N4102D-1 pinout, JAN1N4102D-1 application, or JAN1N4102D-1 equivalent, key selection criteria include its 1% Zener voltage tolerance, JANS qualification status, 8.7 V nominal regulation, DO-35 mechanical robustness, and radiation-hardened performance in harsh environments.
Technical Context
This device functions as a precision shunt voltage regulator operating in reverse breakdown, with cathode-banded polarity indicating the anode-to-cathode orientation for regulation. Its metallurgical bond construction ensures long-term stability under thermal cycling and high-reliability stress conditions.
The JAN1N4102D-1 exhibits a positive temperature coefficient of +0.075 %/°C, enabling predictable drift compensation in reference circuits, and maintains ≤0.5 µA reverse leakage at 7.0 V, supporting low-power biasing in analog front-ends and sensor conditioning stages.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4102US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or wire-wrap | Select when board space is constrained and automated SMT placement is available |
| JANTXV1N4102D | Identical 8.7 V ±1% spec and DO-35 package, but qualified only to JANTXV (not JANS); lower screening rigor | Approved for high-reliability ground systems but not spaceflight or nuclear-rated programs | Select when JANS-level radiation hardness and extended burn-in are not required |
Compared with JAN1N4102D-1, the 1N4102US-1 offers identical regulation performance in a smaller footprint but sacrifices mechanical serviceability, while JANTXV1N4102D reduces cost and lead time at the expense of JANS-level radiation assurance and lifetime screening.

FAQ
What is the Zener voltage tolerance and test current for JAN1N4102D-1?
JAN1N4102D-1 has a nominal Zener voltage of 8.7 V with ±1% tolerance, measured at a Zener test current (IZT) of 250 mA. This tight tolerance eliminates post-manufacture trimming in high-accuracy reference designs and ensures consistent performance across production lots without calibration.
Is JAN1N4102D-1 qualified to JANS level per MIL-PRF-19500/435?
Yes, JAN1N4102D-1 is fully qualified to JANS level per MIL-PRF-19500/435, including extended temperature screening, radiation hardness verification per MicroNote 050, and lot acceptance testing for space-level reliability. This makes it suitable for Class S (spaceflight) applications where failure is not an option.
What is the maximum reverse leakage current for JAN1N4102D-1 at 7.0 V?
The maximum reverse leakage current (IR) for JAN1N4102D-1 is 0.5 µA at 7.0 V and 25 °C. This ultra-low leakage supports energy-efficient biasing in battery-operated instruments and preserves accuracy in high-impedance feedback networks where leakage-induced errors must be minimized.
Does JAN1N4102D-1 have a positive or negative temperature coefficient?
JAN1N4102D-1 has a positive temperature coefficient of +0.075 %/°C. This predictable, linear drift enables accurate thermal compensation in precision reference circuits and simplifies system-level calibration across –65 °C to +175 °C operational range.
What package type and marking does JAN1N4102D-1 use?
JAN1N4102D-1 uses the hermetically sealed DO-35 (DO-204AH) axial-leaded glass package with cathode indicated by a color band. The part is marked with "1N4102D-1" and qualified to JANS level; RoHS compliance is not applicable due to its military specification and lead-based plating.
