Product details
Overview
JAN1N4099D-1 from Microsemi is a 500 mW, 6.8 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 voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4099D-1 datasheet, JAN1N4099D-1 pinout, JAN1N4099D-1 application, or JAN1N4099D-1 equivalent, key selection criteria include its 6.8 V nominal Zener voltage at 250 mA test current, 200 Ω dynamic impedance, 1.0 µA reverse leakage at 5.2 V, 40 µV/√Hz noise density, and radiation-hardened hermetic construction.
Technical Context
This device operates as a precision shunt voltage regulator with a defined breakdown knee at IZK and stable regulation over wide current (250 mA IZT to 76 mA IZM) and temperature (-65°C to +175°C) ranges. Its metallurgical bond ensures low thermal resistance (RθJL = 250°C/W) and minimal parameter drift under thermal stress.
The JAN1N4099D-1 exhibits a positive temperature coefficient of +0.060%/°C and low capacitance (<2 pF typical), making it suitable for low-noise reference circuits where stability and ESD immunity (per MIL-STD-750 method 1020) are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 6.8 V ±1% at 250 mA - enables precise 6.8 V reference generation with tight tolerance for calibration-critical systems |
| Power Dissipation | 500 mW at 25°C - supports stable regulation in compact through-hole designs without forced cooling |
| Dynamic Impedance ZZT | 200 Ω at 250 mA - ensures low output impedance for effective ripple suppression in analog references |
| Noise Density ND | 40 µV/√Hz at 250 mA - minimizes broadband noise contribution in precision instrumentation references |
| Reverse Leakage IR | 1.0 µA max at 5.2 V - guarantees low standby current in battery-backed or low-power monitoring circuits |
| Temp Coefficient αVZ | +0.060%/°C - provides predictable, monotonic voltage shift across military temperature range |
| Thermal Resistance RθJL | 250°C/W @ 10 mm lead length - allows accurate junction temperature estimation for reliability modeling |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or common return; defines 0 V reference point for regulation |
| Cathode | Zener voltage output node | Banded end; supplies regulated 6.8 V when reverse-biased; must be held at higher potential than anode |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4099UR-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads | Required for PCB space-constrained or reflow-only assembly processes | Select when automated SMT placement and smaller footprint outweigh axial-lead serviceability needs |
| JANTXV1N4099D | Identical Zener parameters and 1% tolerance; differs only in qualification level (JANTXV vs JANS) | Approved for high-reliability programs requiring JANTXV screening but not full JANS radiation testing | Choose for cost-sensitive military avionics where full JANS qualification is not mandated |
Compared with JAN1N4099D-1, 1N4099UR-1 offers identical regulation performance in a surface-mount form factor, while JANTXV1N4099D provides equivalent electrical behavior with reduced screening rigor-enabling trade-offs between radiation assurance, procurement lead time, and BOM cost.

FAQ
What is the Zener voltage tolerance of JAN1N4099D-1?
JAN1N4099D-1 has a nominal Zener voltage of 6.8 V with a ±1% tolerance, indicated by the "D" suffix in the part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25°C ambient, and applies across the full military temperature range when derated per the power curve.
Is JAN1N4099D-1 suitable for surface-mount assembly?
No, JAN1N4099D-1 uses a DO-35 axial-leaded glass package and is intended for through-hole mounting. For surface-mount equivalents, consider the 1N4099UR-1 in DO-213AA package - which shares identical electrical characteristics but requires reflow soldering instead of wave or hand soldering.
What is the maximum Zener current IZM for JAN1N4099D-1?
The maximum Zener current IZM for JAN1N4099D-1 is 76.0 mA, calculated from its 500 mW power rating and 6.8 V nominal Zener voltage (IZM = PM(AV)/VZ). This value assumes operation at 25°C lead temperature; derating is required above 50°C per Figure 2 in the datasheet.
Does JAN1N4099D-1 require external heat sinking?
No, JAN1N4099D-1 does not require external heat sinking under typical conditions. Its RθJL of 250°C/W and RθJA of 300°C/W allow safe operation at full 500 mW dissipation with 10 mm lead length on FR4 board, provided ambient temperature remains ≤50°C per the linear derating curve.
How is polarity marked on JAN1N4099D-1?
JAN1N4099D-1 uses a cathode band marking on the glass body - the banded end is the cathode and must be connected to the higher-potential side of the circuit for proper Zener regulation. The unmarked end is the anode and connects to system ground or the lower-potential reference node.
