Product details
Overview
JANS1N4617C-1/TR from Microsemi is a 500 mW, 2.4 V Zener voltage regulator diode in DO-35 glass axial-leaded package, qualified to JANS level per MIL-PRF-19500/435, with ±2% Zener voltage tolerance, 1400 Ω dynamic impedance at 250 mA test current, and 1 μV/√Hz noise density. It serves as a precision low-voltage reference in radiation-hardened military power supply monitoring circuits.
For engineers reviewing the JANS1N4617C-1/TR datasheet, JANS1N4617C-1/TR pinout, JANS1N4617C-1/TR application, or JANS1N4617C-1/TR equivalent, key selection criteria include Zener voltage accuracy (±2%), low-noise operation (1 μV/√Hz), JANS-level reliability qualification, thermal resistance (250 °C/W junction-to-lead), and DO-35 mechanical compatibility for through-hole high-reliability mounting.
Technical Context
This device operates in reverse breakdown to maintain stable 2.4 V regulation across wide current (250 mA IZT) and temperature (-65 to +175 °C) ranges. Its metallurgically bonded construction ensures low leakage (IR ≤ 1.0 μA @ VR = 1.0 V) and radiation hardness per Microsemi MicroNote 050.
The diode exhibits a negative temperature coefficient of -0.075 %/°C and minimal capacitance (typical <2 pF at 1 MHz), making it suitable for low-noise analog references where stability under thermal stress and EMI immunity are critical.
