Product details
Overview
JAN1N4104-1 from Microsemi is a 500 mW, 10.0 V ±5% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to MIL-PRF-19500/435 JAN level for high-reliability applications. It delivers stable voltage regulation at 250 mA test current with 200 Ω dynamic impedance, 0.5 µA reverse leakage at 7.6 V, and +0.080 %/°C temperature coefficient.
For engineers reviewing the JAN1N4104-1 datasheet, JAN1N4104-1 pinout, JAN1N4104-1 application, or JAN1N4104-1 equivalent, this part serves as a precision, low-noise, radiation-hardened voltage reference in military avionics power conditioning, satellite telemetry biasing, and ruggedized industrial sensor signal chains where hermetic sealing and MIL-spec reliability are mandatory.
Technical Context
This Zener diode operates in reverse breakdown with cathode-banded polarity and requires thermal management via lead-to-ambient conduction (RθJA = 300 °C/W). Its metallurgical bond ensures mechanical stability under thermal cycling and shock per MIL-STD-750.
Noise density is specified at 1 µV/√Hz (typical) for voltages ≤6.8 V, scaling up to 40 µV/√Hz at ≥6.8 V; capacitance remains minimal (<3 pF typical), supporting high-frequency reference stability in analog front-ends and PLL loop filters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 10.0 V ±5% at IZT = 250 mA - defines nominal regulation point with tight tolerance for precision biasing |
| Power Dissipation | 500 mW @ TL = 25 °C - supports continuous operation in compact through-hole layouts with linear derating above 50 °C |
| Dynamic Impedance ZZT | 200 Ω max - ensures minimal output voltage shift under load transients in feedback references |
| Reverse Leakage IR | 0.5 µA max @ VR = 7.6 V - enables low-error sensing in high-impedance divider networks |
| Temp. Coefficient αVZ | +0.080 %/°C - provides predictable, monotonic drift for compensated reference designs |
| Noise Density ND | 1 µV/√Hz (typ) - critical for low-noise analog circuits including instrumentation amplifiers and ADC references |
| Junction Temp. Range | –65 to +175 °C - enables deployment in extreme-environment aerospace and downhole systems |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package: hermetically sealed, tin-lead or RoHS-compliant matte-tin plating, cathode indicated by black band. Weight ≈ 0.2 g. Leads extend 25.4–38.1 mm (1.0–1.5 in) from body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Forward conduction terminal / Reference ground node | Connected to circuit common when used as shunt regulator; must sink full load current |
| Cathode (banded end) | Zener breakdown terminal / Regulated output node | Provides stable 10.0 V reference relative to anode; polarity must be observed to avoid forward conduction |
Key Features
| Feature | Design Value |

| Metallurgical bond construction | Eliminates interfacial delamination risk under thermal shock and vibration, ensuring long-term parameter stability |
| Low noise density (1 µV/√Hz) | Enables use in ultra-low-noise analog signal paths without external filtering or post-regulation cleanup |
| Hermetic glass encapsulation | Prevents moisture ingress and parameter drift over decades in humid or corrosive environments |
| Radiation hardness (per MicroNote 050) | Retains electrical performance after exposure to total ionizing dose (TID) levels relevant to LEO and GEO missions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4104US | Same 10.0 V Zener voltage and DO-35 package, but commercial-grade (non-MIL-qualified); no JAN-level screening or traceability. | Lacks radiation hardness, extended temperature validation, and lot-level MIL-STD-750 test reports required for flight hardware. | Select only for cost-sensitive terrestrial industrial prototypes where full MIL compliance is not mandated. |
| JANTX1N4104-1 | Identical electrical specs and DO-35 package, but qualified to JANTX level (enhanced screening vs. JAN), including additional life testing and parametric verification. | Supports higher assurance programs (e.g., NASA Class S, DoD Category I) requiring tighter lot acceptance criteria than JAN. | Choose when program requirements exceed JAN but do not mandate full JANS-level radiation testing or hermeticity validation. |
Compared with 1N4104US and JANTX1N4104-1, the JAN1N4104-1 delivers the baseline MIL-PRF-19500/435 qualification needed for entry-level defense procurement, balancing proven reliability with streamlined screening-making it optimal for avionics LRUs where JANTX overhead is unnecessary and commercial risk is unacceptable.

FAQ
What is the Zener voltage tolerance for JAN1N4104-1?
JAN1N4104-1 has a nominal Zener voltage of 10.0 V with a standard tolerance of ±5%, as defined in the JEDEC-registered specification and confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2. This tolerance applies at IZT = 250 mA and TA = 25 °C. The "C" or "D" suffix would indicate tighter 2% or 1% tolerances, but JAN1N4104-1 uses the base nomenclature and thus carries the 5% tolerance.
Is JAN1N4104-1 RoHS compliant?
No, JAN1N4104-1 is not RoHS compliant. Per the datasheet, RoHS-compliant versions (marked with "e3") are available only for commercial-grade variants-not for JAN, JANTX, JANTXV, or JANS reliability levels. The JAN1N4104-1 uses traditional tin-lead plating per MIL-STD-750 method 2026 and retains the legacy Pb-based finish required for high-reliability solder joint integrity.
What is the maximum Zener current IZM for JAN1N4104-1?
The maximum Zener current IZM for JAN1N4104-1 is 40 mA, as specified in the Electrical Characteristics table (page 3). This value corresponds to the current at which the device reaches its rated 500 mW power dissipation limit at 25 °C lead temperature. Operation above this current requires strict thermal derating per Figure 2's power derating curve.
Does JAN1N4104-1 have radiation hardness certification?
Yes, JAN1N4104-1 is inherently radiation hard, as documented in Microsemi MicroNote 050. While the datasheet does not list specific TID or SEE test data for JAN1N4104-1 individually, the entire 1N4099–1N4135 family-including JAN1N4104-1-is characterized for radiation tolerance consistent with MIL-PRF-19500/435 JANS-level expectations, making it suitable for low-earth orbit and tactical aerospace platforms.
What is the thermal resistance junction-to-ambient (RθJA) for JAN1N4104-1?
The thermal resistance junction-to-ambient (RθJA) for JAN1N4104-1 is 300 °C/W, measured under JEDEC-standard conditions: mounted on FR4 PCB with 1 oz copper, 4 mm² pads, and 1 mm track width over 25 mm length. This value assumes still-air convection and is used to calculate allowable power dissipation at elevated ambient temperatures using the derating curve in Figure 2.
