Product details
Overview
JAN1N4103C-1 from Microsemi is a 500 mW, 9.1 V Zener diode in DO-35 glass package, qualified to JAN level per MIL-PRF-19500/435, with 2% voltage tolerance, 200 Ω dynamic impedance at 250 mA test current, and maximum reverse leakage of 0.5 µA at 7.0 V. It serves as a precision voltage reference in military-grade power regulation and analog signal conditioning circuits.
For engineers reviewing the JAN1N4103C-1 datasheet, JAN1N4103C-1 pinout, JAN1N4103C-1 application, or JAN1N4103C-1 equivalent, key selection criteria include its MIL-qualified reliability, low noise density (1 µV/√Hz), tight 2% Zener voltage tolerance, and thermal stability across –65 °C to +175 °C junction temperature range.
Technical Context
This device operates in reverse breakdown to maintain stable 9.1 V output across wide current (250 mA IZT) and temperature ranges. Its metallurgically bonded construction ensures mechanical robustness and low parameter drift under thermal cycling and radiation exposure.
Designed for high-reliability analog references, it delivers ±2% initial Zener voltage accuracy, +0.080 %/°C temperature coefficient, and minimal capacitance (typ. <1.5 pF) - critical for low-noise biasing in precision amplifiers and ADC reference buffers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4103US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads | Requires PCB redesign for SMT assembly; unsuitable for through-hole prototyping | Select when automated assembly and board space constraints outweigh lead-forming flexibility |
| JANTXV1N4103C-1 | Identical Zener parameters but qualified to JANTXV level (enhanced screening, lower defect rate) | Required for mission-critical flight hardware where burn-in and lot acceptance testing are mandated | Select when higher reliability assurance and extended test documentation are contractually required |
Compared with JAN1N4103C-1, the 1N4103US-1 offers identical regulation performance in a compact SMT form factor but sacrifices mechanical serviceability, while JANTXV1N4103C-1 provides statistically superior reliability at higher cost and longer lead time - both serve distinct program-level requirements rather than functional drop-in replacement roles.

FAQ
What is the Zener voltage and tolerance of JAN1N4103C-1?
JAN1N4103C-1 has a nominal Zener voltage of 9.1 V with a ±2% tolerance, measured at 250 mA test current and 25 °C. This tighter tolerance versus standard ±5% versions enables improved accuracy in closed-loop regulation and reference circuits where voltage margin is constrained.
Is JAN1N4103C-1 suitable for high-temperature operation?
Yes, JAN1N4103C-1 is rated for junction temperatures from –65 °C to +175 °C and features linear power derating from 500 mW at 25 °C to zero at 175 °C. Its hermetic DO-35 glass package and metallurgical bond ensure stable operation in downhole, engine bay, and avionics applications.
Does JAN1N4103C-1 meet MIL-PRF-19500/435 requirements?
Yes, JAN1N4103C-1 is qualified to JAN level per MIL-PRF-19500/435, including screening for mechanical shock, thermal cycling, and parameter verification. Full test data and certificate of conformance are available upon request for defense procurement compliance.
What is the noise performance of JAN1N4103C-1?
JAN1N4103C-1 exhibits a noise density of 1 µV/√Hz at 250 mA test current, verified per Figure 1 test circuit in T4-LDS-0245-2. This low noise enables direct use in high-resolution ADC references and low-drift op-amp bias networks without additional filtering.
How is polarity marked on JAN1N4103C-1?
JAN1N4103C-1 uses a cathode band marking on the glass body - the banded end is the cathode and must be held positive relative to the anode for proper Zener regulation. This marking complies with JEDEC DO-35 polarity conventions and is visible under standard visual inspection.
