Product details
Overview
JANTXV1N4105D-1/TR from Microsemi is a 1% tolerance, 11.0 V, 500 mW axial-leaded glass Zener diode in DO-35 (DO-204AH) package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in military and aerospace power supply circuits.
For engineers reviewing the JANTXV1N4105D-1/TR datasheet, JANTXV1N4105D-1/TR pinout, JANTXV1N4105D-1/TR application, or JANTXV1N4105D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), dynamic impedance (200 Ω at 250 mA), noise density (1 µV/√Hz), temperature coefficient (+0.080 %/°C), and hermetic DO-35 packaging for stable operation across -65°C to +175°C.
Technical Context
This device operates as a precision shunt voltage regulator with metallurgically bonded construction enabling low noise and radiation hardness. It maintains regulation over wide current ranges (IZK to IZM = 0.05–40 mA) and exhibits minimal capacitance (<2 pF typical at 11 V), supporting stable reference performance in analog signal chains and feedback loops.
The JANTXV qualification confirms compliance with MIL-PRF-19500/435 screening including burn-in, temperature cycling, and hermeticity testing. Its ±1% Zener voltage tolerance (denoted by "D" suffix) and +0.080 %/°C temperature coefficient are specified at 25 °C with 250 mA test current, ensuring predictable drift behavior in thermal-stressed environments.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4105US-1TR | Same 11.0 V, 1% DO-35 Zener but commercial-grade (non-mil-qualified); RoHS compliant. | Lacks JANTXV screening; unsuitable for aerospace/military deployments requiring MIL-PRF-19500 compliance. | Select only for cost-sensitive industrial prototypes where full mil-spec qualification is not mandated. |
| JANS1N4105D-1 | Identical electrical specs and DO-35 package; qualified to JANS (highest reliability level) per MIL-PRF-19500/435. | Includes additional screening (e.g., 100% lot acceptance testing, radiation assurance) for spaceflight-critical systems. | Choose when radiation hardness, total dose tolerance >100 krad(Si), or extended lifetime validation is required. |
Compared with JANTXV1N4105D-1/TR, the 1N4105US-1TR offers identical regulation performance at lower cost but no military qualification, while JANS1N4105D-1 adds radiation assurance and extended screening-making it suitable for space-grade designs where JANTXV meets airborne requirements.

FAQ
What is the Zener voltage tolerance of JANTXV1N4105D-1/TR?
JANTXV1N4105D-1/TR has a nominal Zener voltage of 11.0 V with ±1% tolerance, denoted by the "D" suffix in its part number per Microsemi's nomenclature. This tolerance is verified at 25 °C with 250 mA test current and applies across the full operating temperature range of -65°C to +175°C under specified derating conditions.
Is JANTXV1N4105D-1/TR RoHS compliant?
No, JANTXV1N4105D-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants-not for JAN, JANTX, JANTXV, or JANS qualified parts like JANTXV1N4105D-1/TR, which retain traditional tin-lead plating to meet MIL-STD-750 solderability requirements.
What is the maximum Zener current IZM for JANTXV1N4105D-1/TR?
The maximum Zener current IZM for JANTXV1N4105D-1/TR is 40 mA, derived from its 500 mW power rating and 11.0 V Zener voltage (P = V × I → I = 0.5 W / 11 V ≈ 45.5 mA, rounded down to 40 mA per datasheet specification). This value is valid at 25 °C and must be reduced per the linear derating curve above 50 °C lead temperature.
How does the temperature coefficient affect JANTXV1N4105D-1/TR in circuit design?
JANTXV1N4105D-1/TR has a temperature coefficient of +0.080 %/°C, meaning its Zener voltage increases by approximately 8.8 mV per °C rise above 25 °C. Designers must account for this positive drift when setting reference thresholds in wide-temperature-range systems, especially where accuracy better than ±2% over -55°C to +125°C is required.
What packaging option does JANTXV1N4105D-1/TR use and why is it significant?
JANTXV1N4105D-1/TR uses the hermetically sealed DO-35 (DO-204AH) axial-glass package. This construction prevents moisture ingress and parameter shift under thermal cycling or vacuum conditions-critical for aerospace and military applications where long-term stability and MIL-PRF-19500/435 qualification depend on hermetic integrity and metallurgical bonding.
