For engineers reviewing the JANTXV1N4127C-1/TR datasheet, JANTXV1N4127C-1/TR pinout, JANTXV1N4127C-1/TR application, or JANTXV1N4127C-1/TR equivalent, key selection factors include its 56 V nominal Zener voltage at 250 mA test current, 300 Ω maximum dynamic impedance, 0.01 µA maximum reverse leakage at 42.6 V, ±2% voltage tolerance, and -65 °C to +175 °C operating junction temperature range.
Technical Context
This device operates in reverse breakdown to maintain stable reference voltage across wide current (250 mA IZT) and temperature (-65 °C to +175 °C TJ) ranges. Its metallurgical bond construction ensures low noise density (≤1 µV/√Hz below 6.8 V), minimal capacitance, and inherent radiation hardness per Microsemi MicroNote 050.
The JANTXV1N4127C-1/TR exhibits a positive temperature coefficient of +0.100 %/°C above 47 V, enabling predictable thermal drift compensation in regulated supplies. It is rated for 0.5 W average power dissipation with linear derating from 25 °C ambient to zero at 175 °C, and features cathode band polarity marking per MIL-STD-750.
