Product details
Overview
JAN1N4109-1 from Microsemi is a 500 mW, 15.0 V ±5% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded 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 JAN1N4109-1 datasheet, JAN1N4109-1 pinout, JAN1N4109-1 application, or JAN1N4109-1 equivalent, key selection factors include its 15.0 V nominal Zener voltage at 250 mA test current, 100 Ω dynamic impedance, 0.05 µA maximum reverse leakage at 12.0 V, and radiation-hardened hermetic construction suitable for harsh-environment analog reference and overvoltage protection circuits.
Technical Context
This device operates as a precision shunt voltage regulator with a specified Zener voltage of 15.0 V at IZT = 250 mA and exhibits a positive temperature coefficient of +0.085 %/°C. Its metallurgical bond ensures stable breakdown characteristics under thermal cycling and mechanical stress.
The JAN1N4109-1 delivers low noise density (1 µV/√Hz typical at lower voltages), minimal junction capacitance (≈2.5 pF per Figure 3), and maintains regulation across wide current ranges (IZK to IZM = 11.4 mA max) while supporting operation from –65 °C to +175 °C junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N4109-1 | Same electrical specs; qualified to JANTX level with additional screening (burn-in, thermal shock) | Required for programs specifying JANTX reliability level instead of JAN | Select when higher screen severity is mandated by program requirements |
| 1N4109UR-1 | Identical Zener parameters; DO-213AA surface-mount package instead of DO-35 | Suitable for automated SMT assembly; not interchangeable in through-hole designs | Choose for PCB space-constrained or reflow-only production environments |
Compared with JAN1N4109-1, JANTX1N4109-1 adds burn-in and thermal shock screening for extended life in mission-critical systems, while 1N4109UR-1 replaces axial leads with surface-mount terminations-enabling smaller footprints but requiring layout revision and reflow process validation.

FAQ
What is the Zener voltage tolerance for JAN1N4109-1?
JAN1N4109-1 has a nominal Zener voltage of 15.0 V with a standard tolerance of ±5%, consistent with JEDEC registration and MIL-PRF-19500/435 requirements. This tolerance applies at 25 °C with the diode in thermal equilibrium and is verified during JAN-level qualification testing.
Is JAN1N4109-1 RoHS compliant?
No, JAN1N4109-1 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, JANTX, JANTXV, or JANS reliability levels. The JAN1N4109-1 uses traditional tin-lead plating per MIL-STD-750.
What is the maximum Zener current for JAN1N4109-1?
The maximum Zener current (IZM) for JAN1N4109-1 is 11.4 mA, derived from its 500 mW power rating and 15.0 V Zener voltage (P = V × I). This value assumes operation at 25 °C; current must be reduced linearly above 50 °C case temperature per the derating curve in Figure 2.
Does JAN1N4109-1 have radiation hardness certification?
Yes, JAN1N4109-1 is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded structure and hermetic glass package provide tolerance to total ionizing dose (TID), making it suitable for low-earth orbit and nuclear facility applications without additional shielding.
Can JAN1N4109-1 be used in surface-mount designs?
No, JAN1N4109-1 is packaged in axial-leaded DO-35 (DO-204AH) format and is not surface-mount compatible. For SMT implementation, use the functionally equivalent 1N4109UR-1 in DO-213AA package-though this requires PCB redesign and is not a drop-in replacement for JAN1N4109-1.
