Product details
Overview
JAN1N4100D-1 from Microsemi is a 500 mW, 7.5 V ±1% 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 JAN1N4100D-1 datasheet, JAN1N4100D-1 pinout, JAN1N4100D-1 application, or JAN1N4100D-1 equivalent, key selection criteria include its 7.5 V nominal Zener voltage at 250 mA test current, 200 Ω dynamic impedance, 5.7 mA maximum Zener current, -65 °C to +175 °C operating temperature range, and 1% voltage tolerance for precision reference stability.
Technical Context
This device operates as a reverse-biased voltage reference with cathode band marking polarity, requiring banded end positive relative to anode for regulation. Its internal metallurgical bond ensures low noise density (1 µV/√Hz typical at 7.5 V) and radiation hardness per MicroNote 050.
Thermal performance is defined by 250 °C/W junction-to-lead resistance at 10 mm lead length and linear derating from 500 mW at 25 °C to zero at 175 °C ambient, supporting stable operation under thermal stress in sealed military enclosures.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N4100D-1 | Same electrical specs; JANTX qualification level includes additional screening beyond JAN. | Required where enhanced burn-in and parametric testing per MIL-PRF-19500/435 JANTX is mandated. | Select when higher reliability screening is contractually required without changing circuit design. |
| 1N4100UR-1 | Identical Zener parameters but in DO-213AA surface-mount package; no axial leads. | Suitable for automated SMT assembly; not interchangeable in through-hole PCB layouts. | Choose for new designs targeting reflow-compatible packaging while retaining same regulation performance. |
Compared with JAN1N4100D-1, JANTX1N4100D-1 adds screening rigor without altering electrical behavior, whereas 1N4100UR-1 preserves regulation specs but changes mechanical interface-making the former a drop-in reliability upgrade and the latter a layout-dependent form-factor alternative.

FAQ
What is the Zener voltage tolerance for JAN1N4100D-1?
JAN1N4100D-1 has a nominal Zener voltage of 7.5 V with ±1% tolerance, indicated by the "D" suffix in the part number per Microsemi's nomenclature. This tight tolerance is achieved through post-trim screening and supports precision reference applications without external calibration. The 1% spec is guaranteed over the full -65 °C to +175 °C operating temperature range.
Is JAN1N4100D-1 RoHS compliant?
No, JAN1N4100D-1 is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants, not for JAN-level qualified parts. JAN1N4100D-1 uses traditional tin-lead plating on leads to meet MIL-STD-750 solderability requirements and maintain compatibility with legacy military assembly processes.
What is the maximum Zener test current for JAN1N4100D-1?
The maximum Zener test current IZT for JAN1N4100D-1 is 250 mA, as specified in the Electrical Characteristics table. This current defines the operating point at which the 7.5 V Zener voltage and 200 Ω dynamic impedance are measured. Operation above this current requires derating per the power curve to avoid exceeding the 500 mW dissipation limit.
How is polarity marked on JAN1N4100D-1?
JAN1N4100D-1 uses a single black cathode band on the glass body to indicate polarity. The banded end is the cathode and must be connected to the more positive potential in the circuit for proper Zener regulation. The opposite (unbanded) end is the anode and connects to ground or lower potential. This marking complies with JEDEC standards and MIL-PRF-19500/435 requirements.
What is the thermal resistance junction-to-lead for JAN1N4100D-1?
JAN1N4100D-1 has a thermal resistance junction-to-lead (RθJL) of 250 °C/W when measured at 3/8 inch (10 mm) lead length from the package body. This value assumes standard mounting conditions and is used to calculate junction temperature rise under load. Derating begins linearly at 50 °C lead temperature, reaching zero power at 175 °C.
