Product details
Overview
JANTX1N4103-1/TR from Microsemi is a 500 mW, 9.1 V ±5% Zener voltage regulator diode in DO-35 glass axial-leaded package, qualified to JANTX reliability level per MIL-PRF-19500/435, with 200 Ω dynamic impedance at 250 mA test current and 7.0 mA maximum Zener current for precision voltage reference in high-reliability analog circuits.
For engineers reviewing the JANTX1N4103-1/TR datasheet, JANTX1N4103-1/TR pinout, JANTX1N4103-1/TR application, or JANTX1N4103-1/TR equivalent, key selection criteria include Zener voltage tolerance (±5%), thermal resistance (250 °C/W junction-to-lead), noise density (1 µV/√Hz), and MIL-spec qualification level - all critical for aerospace power conditioning and precision biasing.
Technical Context
This device operates as a reverse-biased voltage reference with metallurgically bonded construction ensuring stable breakdown characteristics across -65 °C to +175 °C. Its 9.1 V nominal Zener voltage is specified at 250 mA test current (IZT), with dynamic impedance of 200 Ω measured at 10% rms modulation of IZT.
The JANTX1N4103-1/TR exhibits a positive temperature coefficient of +0.080 %/°C and low capacitance (typical <4 pF at 0 V), enabling use in low-noise, high-stability reference circuits where leakage current (<0.5 µA at 7.3 V) and thermal derating (linear to zero at 175 °C) are design-critical.

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 | Used where PCB space constraints prohibit through-hole mounting | Select when board layout requires SMT assembly and thermal profile permits reflow of glass-body diode |
| JANTXV1N4103-1 | Higher reliability screening (JANTXV level); tighter lot acceptance testing per MIL-PRF-19500/435 | Required for mission-critical subsystems with zero-failure tolerance | Choose when system-level FMEA mandates enhanced burn-in and parametric screening beyond JANTX |
Compared with JANTX1N4103-1/TR, the 1N4103US-1 offers identical regulation performance in a compact SMT form factor but lacks axial-lead mechanical robustness, while JANTXV1N4103-1 delivers superior screening confidence at higher cost and longer lead time - making JANTX1N4103-1/TR the optimal balance of reliability, manufacturability, and cost for most high-integrity analog designs.

FAQ
What is the Zener voltage tolerance for JANTX1N4103-1/TR?
JANTX1N4103-1/TR has a nominal Zener voltage of 9.1 V with a ±5% tolerance, as defined by JEDEC standard and verified per MIL-PRF-19500/435 test requirements. This tolerance applies at 250 mA test current and 25 °C ambient temperature, and remains stable across the full -65 °C to +175 °C junction temperature range due to its metallurgical bond construction.
Is JANTX1N4103-1/TR RoHS compliant?
No, JANTX1N4103-1/TR is not RoHS compliant. The "TR" suffix indicates tape-and-reel packaging, but RoHS compliance (designated by "e3") is only available on commercial-grade versions of this family, not on JANTX-level military-qualified parts. JANTX1N4103-1/TR uses traditional tin-lead plating per MIL-STD-750 Method 2026 for solderability and reliability in high-reliability applications.
What is the maximum Zener current rating for JANTX1N4103-1/TR?
The maximum Zener current (IZM) for JANTX1N4103-1/TR is 40 mA, derived from its 500 mW power rating and 9.1 V Zener voltage (P = V × I → I = 0.5 W / 9.1 V ≈ 55 mA, derated to 40 mA per datasheet Table on Page 3). This value assumes operation at 25 °C lead temperature; current must be linearly reduced above 50 °C per the derating curve in Figure 2.
How does the temperature coefficient affect JANTX1N4103-1/TR performance?
JANTX1N4103-1/TR has a temperature coefficient of +0.080 %/°C, meaning its Zener voltage increases by approximately 7.3 mV per °C rise in junction temperature. At 9.1 V nominal, this results in +0.73 V drift over a 100 °C range. Designers must account for this in closed-loop references or use compensation networks where sub-0.1% stability is required across wide temperature spans.
Can JANTX1N4103-1/TR be used in surface-mount designs?
No, JANTX1N4103-1/TR is packaged in the axial-leaded DO-35 (DO-204AH) glass case and is intended for through-hole mounting. For surface-mount equivalents, consider the 1N4103US-1 in DO-213AA package - which shares identical electrical specifications but differs in mechanical form factor and qualification level. JANTX1N4103-1/TR itself cannot be reliably mounted or reflowed in SMT processes.
