Product details
Overview
JANS1N4100C-1/TR from Microsemi is a 500 mW, 7.5 V Zener diode in DO-35 glass package, qualified to JANS level per MIL-PRF-19500/435, with ±2% voltage tolerance, 250 mA test current, and 200 Ω dynamic impedance at 25 °C - used for precision voltage regulation in radiation-hardened aerospace power supplies.
For engineers reviewing the JANS1N4100C-1/TR datasheet, JANS1N4100C-1/TR pinout, JANS1N4100C-1/TR application, or JANS1N4100C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), JANS-level reliability qualification, DO-35 axial-leaded hermetic packaging, noise density (1 µV/√Hz), and thermal resistance (250 °C/W junction-to-lead).
Technical Context
This device operates as a reverse-biased voltage reference with metallurgically bonded construction for enhanced reliability. It delivers stable 7.5 V regulation across 5–100 mA operating current and -65 °C to +175 °C temperature range, meeting MIL-PRF-19500/435 Class JANS requirements for high-reliability military and space systems.
Its low noise density (1 µV/√Hz) and minimal capacitance (≈4 pF at 7.5 V) support use in low-noise analog references and precision biasing. The cathode band marking and tin-lead plating ensure unambiguous polarity identification and solderability per MIL-STD-750 Method 2026.
