Product details
Overview
JAN1N4102C-1/TR from Microsemi is a 500 mW, 8.7 V ±2% metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies, reference circuits, and overvoltage protection.
For engineers reviewing the JAN1N4102C-1/TR datasheet, JAN1N4102C-1/TR pinout, JAN1N4102C-1/TR application, or JAN1N4102C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), dynamic impedance (200 Ω at 250 mA), noise density (1 µV/√Hz), temperature coefficient (+0.075 %/°C), and JANS-level radiation hardness.
Technical Context
This axial-leaded Zener diode operates in reverse breakdown with cathode band marking polarity, requiring banded end positive relative to anode for regulation. Its internal metallurgical bond ensures stable junction behavior across -65 °C to +175 °C operating range and low capacitance (typical <2 pF at 8.7 V).
Thermal resistance is 250 °C/W junction-to-lead (3/8″ lead length) and 300 °C/W junction-to-ambient on FR4 board. Power derating begins linearly at 50 °C ambient, reaching zero at 175 °C - critical for high-temperature avionics designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 8.7 V ±2% at 250 mA test current - enables precise mid-range voltage reference with tight tolerance for analog sensing and feedback loops. |
| Power Dissipation | 500 mW at 25 °C, linearly derated to zero at 175 °C - defines maximum continuous thermal load without forced cooling. |
| Dynamic Impedance ZZT | 200 Ω at 250 mA - determines regulation stiffness; lower values improve line/load regulation in precision references. |
| Noise Density | 1 µV/√Hz at 250 mA - ultra-low broadband noise critical for low-noise instrumentation and ADC reference buffers. |
| Temp. Coefficient αVZ | +0.075 %/°C - predictable positive drift allows compensation in temperature-stable reference designs. |
| Reverse Leakage IR | 0.5 µA at 7.0 V - minimal leakage preserves accuracy in high-impedance bias networks. |
| Junction Temp. Range | -65 °C to +175 °C - supports operation in extreme environments including space-grade and engine-mounted electronics. |
Pinout & Package
DO-35 (DO-204AH) hermetically sealed axial-glass package with tin-lead or RoHS-compliant matte-tin plating; cathode indicated by black band; weight ≈ 0.2 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Reference ground node | Connected to circuit common; must be at lower potential than cathode during regulation. |
| Cathode (banded end) | Zener output node | Provides regulated 8.7 V when reverse-biased; polarity marking prevents incorrect installation. |
Key Features
| Feature | Design Value |
|---|---|
| Metallurgical bonding | Eliminates interfacial voids and delamination risk - ensures long-term stability under thermal cycling and radiation exposure. |
| JANS qualification | Fully screened to MIL-PRF-19500/435 Class S - guarantees performance in mission-critical systems requiring radiation hardness and lot traceability. |
| Low noise density | 1 µV/√Hz at 8.7 V - outperforms standard Zeners by >10× in noise-sensitive applications like precision DAC references. |
| Hermetic glass seal | Prevents moisture ingress and parameter drift - essential for 20+ year field life in sealed military enclosures. |
| ESD immunity | Non-sensitive per MIL-STD-750 Method 1020 - eliminates need for external ESD protection in handling and assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4102US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads. | Required for automated SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical retention. | Select when board space is constrained and reflow compatibility is mandatory. |
| JANTXV1N4102C-1 | Identical Zener parameters and ±2% tolerance, but qualified to JANTXV level (not JANS); lower screening rigor and no radiation hardness documentation. | Suitable for non-space, non-nuclear defense programs where full JANS testing is not mandated. | Choose for cost-sensitive tactical systems where radiation tolerance is not required. |
Compared with JAN1N4102C-1/TR, 1N4102US-1 offers identical regulation performance in a compact SMT form factor but lacks axial mounting flexibility, while JANTXV1N4102C-1 reduces procurement cost and lead time at the expense of JANS-level radiation assurance and extended lifetime screening.
