Product details
Overview
JAN1N4100C-1 from Microsemi is a 500 mW, 7.5 V ±2% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4100C-1 datasheet, JAN1N4100C-1 pinout, JAN1N4100C-1 application, or JAN1N4100C-1 equivalent, key selection factors include its 7.5 V nominal Zener voltage at 250 mA test current, 200 Ω dynamic impedance, 5.7 mA maximum Zener current, ±2% voltage tolerance, and -65 °C to +175 °C operating temperature range.
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) and temperature (-65 °C to +175 °C) ranges. Its internal metallurgical bond ensures low noise density (1 µV/√Hz typical at 7.5 V) and radiation hardness per MicroNote 050.
The diode exhibits a positive temperature coefficient of +0.065 %/°C and minimal capacitance (typical <2 pF), making it suitable for low-noise reference and biasing circuits where stability under thermal stress and ESD immunity (MIL-STD-750 method 1020) are critical.
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-1 | Same electrical specs but in surface-mount DO-213AA package; no axial leads. | Used where board space is constrained and reflow assembly is required. | Select when transitioning from through-hole to SMT while retaining identical regulation performance. |
| JANTXV1N4100C-1 | Identical electrical and mechanical specs but qualified to JANTXV level per MIL-PRF-19500/435. | Required for programs mandating enhanced screening (burn-in, thermal shock, life test). | Select when program specifications require JANTXV-level reliability assurance beyond JAN. |
Compared with JAN1N4100C-1, the 1N4100US-1 offers identical regulation but enables automated SMT placement, while JANTXV1N4100C-1 adds rigorous screening for extended mission life-neither is pin-compatible due to differing packages or qualification scope.

FAQ
What is the Zener voltage tolerance of JAN1N4100C-1?
JAN1N4100C-1 has a nominal Zener voltage of 7.5 V with a ±2% tolerance, indicated by the "C" suffix in its nomenclature per Microsemi's part numbering standard. This tolerance is verified at 250 mA test current and 25 °C ambient, and remains stable across its qualified temperature range.
Is JAN1N4100C-1 suitable for high-temperature operation?
Yes, JAN1N4100C-1 is rated for junction temperatures from -65 °C to +175 °C and is fully qualified per MIL-PRF-19500/435 at JAN level. Its metallurgically bonded construction and hermetic glass package ensure parameter stability and long-term reliability in sustained high-temperature environments such as downhole or engine-mounted electronics.
What does the "-1" suffix mean in JAN1N4100C-1?
The "-1" suffix in JAN1N4100C-1 denotes compliance with Microsemi's standard revision T4-LDS-0245-2, indicating the device meets the latest electrical, mechanical, and qualification requirements specified in that datasheet revision, including updated noise density, impedance, and derating curves.
How is polarity marked on JAN1N4100C-1?
JAN1N4100C-1 uses a cathode band marking on the glass body to indicate polarity. The banded end is the cathode and must be connected to the higher-potential node for proper Zener regulation; the opposite lead is the anode and connects to the lower-potential node or ground.
Does JAN1N4100C-1 require external heat sinking?
No, JAN1N4100C-1 is rated for 500 mW dissipation at 25 °C lead temperature and features a thermal resistance of 250 °C/W junction-to-lead (with 10 mm lead length). In typical PCB mounting with 4 mm² copper pads, it operates within safe limits up to ~100 mW without heatsinking; higher power requires derating per Figure 2 in the datasheet.
