Product details
Overview
JAN1N4102-1 from Microsemi is a 500 mW, 8.7 V ±5% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) package, qualified to JAN level per MIL-PRF-19500/435. 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 for high-reliability power supply and reference applications.
For engineers reviewing the JAN1N4102-1 datasheet, JAN1N4102-1 pinout, JAN1N4102-1 application, or JAN1N4102-1 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (250 °C/W junction-to-lead), reverse leakage (0.5 µA @ 7.0 V), noise performance, and military-grade qualification status.
Technical Context
This Zener diode operates in reverse breakdown to maintain precise DC voltage under varying load and temperature conditions. Its metallurgical bond ensures mechanical stability and long-term parameter consistency, while the hermetically sealed DO-35 glass package provides moisture resistance and high reliability in harsh environments.
The device exhibits a positive temperature coefficient of +0.075 %/°C, enabling predictable drift behavior in temperature-critical references. Its low capacitance (typical <2 pF at 0 V, per Figure 3) supports high-frequency stability in filtering and clamping circuits without signal distortion.
Key Specifications

|---|---|
| Zener Voltage VZ | 8.7 V ±5% at 250 mA - defines nominal regulation point with tight tolerance for precision reference use |
| Power Dissipation | 500 mW at 25 °C lead temperature - sets maximum continuous power handling before thermal derating begins |
| Dynamic Impedance ZZT | 200 Ω at 250 mA - determines output voltage variation under load transients; lower values improve regulation accuracy |
| Reverse Leakage IR | 0.5 µA at 7.0 V - ensures minimal parasitic current in standby or high-impedance bias networks |
| Noise Density | 1 µV/√Hz - enables low-noise analog references in instrumentation and sensor front-ends |
| Temp Coefficient αVZ | +0.075 %/°C - quantifies voltage drift over temperature; supports compensation design in wide-range systems |
| Junction Temp Range | –65 °C to +175 °C - validates operation in aerospace, defense, and downhole industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4102US | Same 8.7 V rating and DO-35 package but commercial-grade (non-military); RoHS-compliant matte-tin plating. | Lacks JAN qualification screening and extended temperature validation; suitable for non-safety-critical industrial use. | Select when cost sensitivity outweighs MIL-spec requirements and environmental conditions remain within commercial limits. |
| JANTX1N4102 | Identical electrical specs and DO-35 package; qualified to JANTX level (higher screening than JAN, including burn-in and life test). | Approved for higher-reliability programs requiring extended lot traceability and failure rate data per MIL-HDBK-217. | Choose when system FMEA mandates enhanced reliability metrics beyond baseline JAN qualification. |
Compared with JAN1N4102-1, 1N4102US offers cost savings and RoHS compliance but sacrifices military screening and extreme-temperature validation, while JANTX1N4102 adds burn-in and life testing for mission-critical deployments-neither is pin-compatible drop-in due to differing qualification documentation and traceability requirements.

FAQ
What is the Zener voltage tolerance for JAN1N4102-1?
JAN1N4102-1 has a nominal Zener voltage of 8.7 V with a ±5% tolerance, as defined by JEDEC standards and verified per MIL-PRF-19500/435 screening. This tolerance applies at 250 mA test current and 25 °C ambient, and remains stable across its qualified temperature range due to metallurgical bond construction.
Is JAN1N4102-1 suitable for surface-mount applications?
No, JAN1N4102-1 uses the axial-leaded DO-35 (DO-204AH) through-hole package and is not surface-mount compatible. For SMT equivalents, Microsemi offers the 1N4102UR-1 in DO-213AA and 1PMT4102 in DO-216 packages-both share identical electrical specs but differ in mounting and qualification level.
What is the maximum reverse leakage current for JAN1N4102-1?
JAN1N4102-1 specifies a maximum reverse leakage current (IR) of 0.5 µA at 7.0 V reverse voltage and 25 °C. This low leakage supports high-impedance bias networks and minimizes power loss in battery-backed or ultra-low-power monitoring circuits.
Does JAN1N4102-1 require derating above 25 °C?
Yes, JAN1N4102-1 must be linearly derated from 500 mW starting at 25 °C ambient on a typical PCB, reaching zero dissipation at 175 °C. Derating follows a slope of –3.33 mW/°C, based on RθJA = 300 °C/W and RθJL = 250 °C/W for lead-mounted configurations.
How does the temperature coefficient affect JAN1N4102-1 performance?
JAN1N4102-1 has a temperature coefficient of +0.075 %/°C, meaning its Zener voltage increases by approximately 6.5 mV per °C rise above 25 °C. This predictable positive drift allows for passive compensation in precision reference designs using complementary negative-coefficient components.
