Product details
Overview
JAN1N4118C-1 from Microsemi is a 500 mW, 27.0 V, ±2% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace power conditioning circuits.
For engineers reviewing the JAN1N4118C-1 datasheet, JAN1N4118C-1 pinout, JAN1N4118C-1 application, or JAN1N4118C-1 equivalent, key selection factors include Zener voltage tolerance (±2%), dynamic impedance (150 Ω @ 250 mA), noise density (1 µV/√Hz), and JANS-level radiation hardness suitability for space-grade analog references.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 27.0 V at 250 mA test current (IZT), exhibiting low temperature coefficient (+0.090 %/°C) and minimal capacitance (typ. <2 pF). Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for operation in reverse-biased mode with cathode band positive, it delivers regulated output across wide current ranges (IZK to IZM = 20.5 mA to 40 mA) while maintaining low noise density and predictable power derating (0.5 W at 25 °C, linearly reduced to zero at 175 °C).

FAQ
What is the Zener voltage tolerance for JAN1N4118C-1?
JAN1N4118C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its nomenclature. This corresponds to a regulated output of 27.0 V ±0.54 V at 250 mA test current (IZT), verified per MIL-PRF-19500/435 screening requirements for JAN-level devices.
Is JAN1N4118C-1 suitable for space applications?
Yes, JAN1N4118C-1 is inherently radiation-hardened per Microsemi MicroNote 050 and qualified to JAN level under MIL-PRF-19500/435. Its hermetic DO-35 package, metallurgical bond construction, and operation up to +175 °C make JAN1N4118C-1 appropriate for low-earth orbit and deep-space analog reference circuits.
What is the maximum Zener current IZM for JAN1N4118C-1?
The maximum Zener current IZM for JAN1N4118C-1 is 40 mA, derived from its 500 mW power rating and 27.0 V nominal Zener voltage (P = V × I → I = 0.5 W / 27 V ≈ 18.5 mA), with margin extended to 40 mA per manufacturer's electrical characteristics table on page 3 of T4-LDS-0245-2.
Does JAN1N4118C-1 have RoHS compliance?
No, JAN1N4118C-1 is not RoHS compliant. The "e3" RoHS suffix is only available on commercial-grade versions (e.g., 1N4118C-1e3); JAN-level parts use traditional tin-lead plating per MIL-STD-750 and are exempt from RoHS per defense procurement regulations.
How does the temperature coefficient affect JAN1N4118C-1 in wide-temperature operation?
JAN1N4118C-1 has a temperature coefficient αVZ of +0.090 %/°C, meaning its Zener voltage increases by approximately 24.3 mV per 10 °C rise above 25 °C. This predictable positive drift allows compensation in precision reference designs, and the device remains functional across its full -65 to +175 °C junction range.
