Product details
Overview
JAN1N4100-1 from Microsemi is a 500 mW, 7.5 V axial-leaded glass Zener diode in DO-35 (DO-204AH) package, qualified to JAN level per MIL-PRF-19500/435. It delivers ±5% Zener voltage tolerance, 250 mA test current, 200 Ω dynamic impedance at IZT, and operates across –65 °C to +175 °C junction temperature for precision voltage regulation in military-grade power supplies.
For engineers reviewing the JAN1N4100-1 datasheet, JAN1N4100-1 pinout, JAN1N4100-1 application, or JAN1N4100-1 equivalent, key selection criteria include its 7.5 V nominal Zener voltage, 500 mW power rating, DO-35 mechanical form factor, MIL-qualified reliability level, and low noise density of 1 µV/√Hz - all critical for high-stability reference and regulation circuits.
Technical Context
This device functions as a reverse-biased voltage reference with metallurgically bonded construction for enhanced thermal stability and radiation hardness. Its Zener breakdown occurs at 7.5 V with 250 mA test current, exhibiting 200 Ω dynamic impedance and +0.065 %/°C temperature coefficient - enabling predictable regulation over wide temperature ranges.
The JAN1N4100-1 is hermetically sealed in glass, features cathode band polarity marking, and supports operation up to 175 °C junction temperature. Its 300 °C/W junction-to-ambient thermal resistance requires careful PCB copper layout for thermal management under full 500 mW dissipation.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4100US | Same 7.5 V Zener voltage, but in surface-mount DO-213AA package; no MIL qualification | Lacks JAN-level screening and radiation hardness; intended for commercial industrial use only | Select when board space is constrained and military reliability not required |
| JANTX1N4100-1 | Identical electrical specs and DO-35 package, but qualified to JANTX level per MIL-PRF-19500/435 | Higher screening severity (e.g., burn-in, life test) and tighter lot traceability than JAN | Select when extended reliability testing and longer qualification records are mandated |
Compared with JAN1N4100-1, 1N4100US offers footprint reduction but sacrifices hermeticity and radiation tolerance, while JANTX1N4100-1 provides enhanced process controls and screening depth - making JAN1N4100-1 the optimal balance of performance, qualification, and cost for mid-tier defense programs.

FAQ
What is the Zener voltage tolerance for JAN1N4100-1?
JAN1N4100-1 has a nominal Zener voltage of 7.5 V with a standard tolerance of ±5%, as defined in the JEDEC-registered specification and verified per MIL-PRF-19500/435 screening requirements. This tolerance applies at 25 °C with 250 mA test current and remains stable across its qualified temperature range.
Is JAN1N4100-1 RoHS compliant?
No, JAN1N4100-1 is not RoHS compliant. The "e3" RoHS suffix is only available on commercial-grade versions (e.g., 1N4100-1e3); JAN-level parts retain traditional tin-lead plating to meet MIL-STD-750 solderability and reliability requirements for high-reliability applications.
What is the maximum Zener current IZM for JAN1N4100-1?
The maximum Zener current IZM for JAN1N4100-1 is 40 mA, derived from its 500 mW power rating and 7.5 V Zener voltage (IZM = PM(AV)/VZ). This value assumes thermal equilibrium at 25 °C and must be reduced per the linear derating curve above 50 °C lead temperature.
Does JAN1N4100-1 have radiation hardness certification?
Yes, JAN1N4100-1 is inherently radiation hard as documented in Microsemi MicroNote 050. It retains functional integrity after total ionizing dose (TID) exposure exceeding 100 krad(Si), making it suitable for space and nuclear instrumentation applications without additional shielding.
What package type does JAN1N4100-1 use?
JAN1N4100-1 uses the DO-35 (also designated DO-204AH) axial-leaded hermetically sealed glass package. Dimensions conform to MIL-PRF-19500/435, with body diameter 1.42–2.29 mm, body length 3.56–5.08 mm, and lead length ≥25.4 mm.
