Product details
Overview
JAN1N4103-1 from Microsemi is a 500 mW, 9.1 V 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 ±5% Zener voltage tolerance, 200 Ω dynamic impedance at 250 mA test current, and operates across –65 °C to +175 °C junction temperature range.
For engineers reviewing the JAN1N4103-1 datasheet, JAN1N4103-1 pinout, JAN1N4103-1 application, or JAN1N4103-1 equivalent, key selection factors include its military-grade reliability qualification, low noise density (1 µV/√Hz), stable temperature coefficient (+0.080 %/°C), and hermetically sealed glass construction suitable for aerospace power regulation and precision reference circuits.
Technical Context
The JAN1N4103-1 functions as a reverse-biased voltage regulator with cathode band marking polarity. Its metallurgical bond ensures mechanical robustness under thermal cycling and shock, critical for space-qualified designs. The device exhibits 0.5 W average power dissipation with linear derating above 50 °C lead temperature.
Zener regulation occurs at IZT = 250 mA, where VZ = 9.1 V is specified. Dynamic impedance ZZT = 200 Ω is measured with 10% rms ac modulation at 60 Hz superimposed on IZT, per MicroNote 202. Reverse leakage IR ≤ 0.5 µA is guaranteed at VR = 7.0 V.
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 |
|---|---|---|---|
| 1N4103US | Same 9.1 V nominal Zener voltage and DO-35 package, but commercial-grade (non-military) qualification; no MIL-PRF-19500/435 compliance | Lacks JAN-level screening, radiation hardness, and extended temperature validation-unsuitable for flight hardware | Select only for cost-sensitive terrestrial industrial prototypes where full military qualification is not required |
| JANTX1N4103-1 | Identical electrical specs and DO-35 package, but qualified to JANTX level (higher screening than JAN, includes burn-in and lot acceptance testing) | Higher reliability screening increases cost and lead time; used where failure modes demand tighter parametric limits and longer life validation | Prefer when system FMEA requires enhanced defect elimination beyond baseline JAN requirements |
Compared with 1N4103US and JANTX1N4103-1, the JAN1N4103-1 provides the optimal balance of military-grade reliability, proven radiation tolerance, and production-ready availability-making it the default choice for Class B space applications and certified avionics where qualification traceability is mandatory.

FAQ
What is the Zener voltage tolerance for JAN1N4103-1?
JAN1N4103-1 has a nominal Zener voltage of 9.1 V with ±5% tolerance, consistent with JEDEC-standard 1N-series Zener diodes. This tolerance is verified at 250 mA test current and 25 °C ambient, and applies across the full qualified temperature range when derated per MIL-PRF-19500/435 requirements.
Does JAN1N4103-1 require heatsinking in standard PCB layouts?
No, JAN1N4103-1 does not require external heatsinking in typical through-hole FR4 layouts. Its 0.5 W power rating is thermally managed via 250 °C/W junction-to-lead resistance when mounted with 3/8″ lead length, enabling direct use in compact avionics and instrumentation boards without thermal vias or copper pours.
Is JAN1N4103-1 RoHS compliant?
No, JAN1N4103-1 is not RoHS compliant. Per the T4-LDS-0245-2 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. JAN1N4103-1 uses traditional tin-lead plating per MIL-STD-750.
What is the maximum reverse leakage current for JAN1N4103-1?
JAN1N4103-1 guarantees maximum reverse leakage current IR ≤ 0.5 µA at VR = 7.0 V and 25 °C. This value remains within specification across the full –65 °C to +175 °C junction temperature range, supporting low-power standby modes in battery-operated systems.
Can JAN1N4103-1 be used in surface-mount designs?
No, JAN1N4103-1 is exclusively packaged in axial-leaded DO-35 (DO-204AH) glass. Surface-mount equivalents exist (e.g., 1N4103UR-1 in DO-213AA), but they are distinct orderable parts with different qualification levels and thermal profiles-not drop-in replacements for JAN1N4103-1.
