Product details
Overview
JANTXV1N4105D-1 from Microsemi is a 1% tolerance, 11.0 V, 500 mW axial-leaded Zener diode in DO-35 glass package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in military and aerospace power conditioning circuits.
For engineers reviewing the JANTXV1N4105D-1 datasheet, JANTXV1N4105D-1 pinout, JANTXV1N4105D-1 application, or JANTXV1N4105D-1 equivalent, key selection factors include its 1% Zener voltage tolerance, 250 mA test current, 200 Ω dynamic impedance at IZT, low 0.05 µA reverse leakage at 8.5 V, and radiation-hardened metallurgical bond construction.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 11.0 V at 250 mA test current (IZT), exhibiting +0.080 %/°C temperature coefficient and 200 Ω dynamic impedance (ZZT). Its metallurgically bonded junction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for operation in the reverse-biased breakdown region, JANTXV1N4105D-1 delivers regulated output with minimal noise density (≤1 µV/√Hz below 6.8 V) and low capacitance (typical <2 pF), supporting stable reference generation in analog signal chains and power supply feedback loops.

FAQ
What is the Zener voltage tolerance for JANTXV1N4105D-1?
JANTXV1N4105D-1 has a nominal Zener voltage of 11.0 V with ±1% tolerance, as indicated by the "D" suffix in the part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, and applies across the full qualified operating temperature range of -65 to +175 °C.
Is JANTXV1N4105D-1 RoHS compliant?
No, JANTXV1N4105D-1 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, which retain tin-lead plating for solderability and reliability in high-reliability applications.
What does the "JANTXV" prefix indicate for JANTXV1N4105D-1?
The "JANTXV" prefix denotes compliance with the highest active military qualification level under MIL-PRF-19500/435, including extended temperature screening (-65 to +175 °C), burn-in, and lot traceability. JANTXV1N4105D-1 undergoes more rigorous testing than JAN or JANTX versions, making it suitable for critical aerospace and defense platforms.
What is the maximum Zener current IZM for JANTXV1N4105D-1?
The maximum Zener current IZM for JANTXV1N4105D-1 is 40 mA, derived from its 500 mW power rating and 11.0 V Zener voltage (P = V × I → I = 0.5 W / 11.0 V ≈ 45.5 mA, derated to 40 mA per datasheet table). Operation beyond this current risks exceeding thermal limits even at 25 °C ambient.
How is polarity marked on JANTXV1N4105D-1?
JANTXV1N4105D-1 uses a cathode band marking on the glass DO-35 body: the banded end is the cathode and must be held positive relative to the anode to achieve Zener regulation. This polarity is consistent across all 1N4099–1N4135-1 series devices and is verified per MIL-STD-750 method 2026 for solderability and marking legibility.
