Product details
Overview
JANTXV1N4114D-1/TR from Microsemi is a 20 V, 1% tolerance, 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 JANTXV1N4114D-1/TR datasheet, JANTXV1N4114D-1/TR pinout, JANTXV1N4114D-1/TR application, or JANTXV1N4114D-1/TR equivalent, this page delivers verified Zener voltage (20.0 V @ 250 mA), dynamic impedance (150 Ω), temperature coefficient (+0.090 %/°C), noise density (1 µV/√Hz), and hermetic DO-35 packaging details critical for precision reference and radiation-hardened designs.
Technical Context
This device operates as a two-terminal voltage regulator in reverse-biased breakdown mode, with metallurgical bonding ensuring stable junction characteristics across -65 °C to +175 °C. Its 1% Zener voltage tolerance and low noise density support precision analog references where drift and spectral purity matter.
The JANTXV qualification confirms compliance with MIL-PRF-19500/435 screening including burn-in, thermal shock, and life testing. Its DO-35 package provides hermetic sealing, ESD immunity per MIL-STD-750 Method 1020, and minimal capacitance (~2 pF at 20 V) for high-frequency stability.
