Product details
Overview
JANTX1N4104C-1 from Microsemi is a 500 mW, 10.0 V ±2% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability regulation. It delivers stable voltage reference with 200 Ω dynamic impedance at 250 mA test current, 0.5 µA reverse leakage at 7.6 V, and +0.080 %/°C temperature coefficient - used in precision power supply feedback and analog sensor biasing.
For engineers reviewing the JANTX1N4104C-1 datasheet, JANTX1N4104C-1 pinout, JANTX1N4104C-1 application, or JANTX1N4104C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), thermal resistance (250 °C/W junction-to-lead), noise density (≤1 µV/√Hz), and MIL-qualified reliability for aerospace and defense systems.
Technical Context
This device operates as a two-terminal voltage regulator in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond construction ensures low noise and radiation hardness per MicroNote 050, while the hermetically sealed DO-35 glass package maintains stability across -65 °C to +175 °C junction temperature range.
It exhibits a linear power derating curve from 500 mW at 25 °C ambient to zero at 175 °C, with specified Zener impedance measured at 10% AC modulation of IZT (25 µA rms). The +0.080 %/°C temperature coefficient enables predictable drift compensation in reference circuits.

FAQ
What is the Zener voltage tolerance of JANTX1N4104C-1?
JANTX1N4104C-1 has a nominal Zener voltage of 10.0 V with a tolerance of ±2%, indicated by the "C" suffix in its part number per Microsemi's nomenclature. This tighter tolerance enables higher-accuracy regulation than standard ±5% variants, supporting precision feedback and reference applications where voltage drift must be minimized across temperature and aging.
Is JANTX1N4104C-1 suitable for high-radiation environments?
Yes, JANTX1N4104C-1 is inherently radiation hard due to its metallurgically bonded construction, as documented in Microsemi MicroNote 050. It is qualified to MIL-PRF-19500/435 JANTX level, which includes screening for total ionizing dose (TID) and displacement damage, making JANTX1N4104C-1 appropriate for satellite, avionics, and nuclear instrumentation applications.
What is the maximum reverse leakage current for JANTX1N4104C-1?
The maximum reverse leakage current (IR) for JANTX1N4104C-1 is 0.5 µA at VR = 7.6 V, as specified in the Electrical Characteristics table. This low leakage ensures minimal error contribution in high-impedance bias networks and precision reference circuits where current draw must remain negligible.
Does JANTX1N4104C-1 require special ESD handling?
No, JANTX1N4104C-1 is non-sensitive to ESD per MIL-STD-750 Method 1020. Its construction and packaging eliminate the need for ESD-safe workstations, wrist straps, or conductive foam during handling and assembly - simplifying manufacturing flow for JANTX1N4104C-1 in defense and aerospace production lines.
What is the thermal resistance junction-to-lead for JANTX1N4104C-1?
JANTX1N4104C-1 has a thermal resistance junction-to-lead (RθJL) of 250 °C/W when mounted with 3/8 inch (10 mm) lead length from body, per the Maximum Ratings table. This value informs heatsinking requirements and power derating calculations for sustained operation above ambient temperature.
