Product details
Overview
JANS1N4116C-1/TR from Microsemi is a 24.0 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense systems. It delivers stable voltage regulation at 250 mA test current with 150 Ω dynamic impedance and +0.090 %/°C temperature coefficient.
For engineers reviewing the JANS1N4116C-1/TR datasheet, JANS1N4116C-1/TR pinout, JANS1N4116C-1/TR application, or JANS1N4116C-1/TR equivalent, key selection criteria include Zener voltage tolerance (2%), radiation hardness, hermetic glass packaging, noise density (1 µV/√Hz), and MIL-qualified thermal derating behavior up to 175 °C junction temperature.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond construction ensures low leakage (<0.01 µA at 18.3 V) and minimal capacitance (typical <1.5 pF), critical for low-noise analog references and radiation-tolerant power conditioning.
The JANS1N4116C-1/TR exhibits a positive temperature coefficient (+0.090 %/°C), enabling predictable drift compensation in temperature-stable reference designs. Its 250 °C/W junction-to-lead thermal resistance supports reliable operation under sustained 500 mW dissipation when leads are mounted at 10 mm length per MIL-STD-750.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4116US-1 | Same 24 V, 2% spec but in DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or wire-wrap | Select when board space is constrained and automated placement is available |
