Product details
Overview
JANTX1N4104-1 from Microsemi is a 500 mW, 10.0 V ±5% metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation. It delivers 250 mA Zener test current, 200 Ω dynamic impedance at IZT, 0.5 µA reverse leakage at 7.6 V, and +0.080 %/°C temperature coefficient - used in precision reference and power supply feedback circuits.
For engineers reviewing the JANTX1N4104-1 datasheet, JANTX1N4104-1 pinout, JANTX1N4104-1 application, or JANTX1N4104-1 equivalent, key selection factors include its MIL-qualified reliability grade, low noise density (≤1 µV/√Hz below 6.8 V), hermetic DO-35 packaging, and thermal resistance of 250 °C/W junction-to-lead at 10 mm lead length.
Technical Context
This device operates as a two-terminal voltage regulator in reverse-bias breakdown mode, with cathode band marking polarity. Its metallurgical bond ensures stable Zener voltage under thermal cycling and radiation exposure per MicroNote 050.
The JANTX1N4104-1 exhibits a +0.080 %/°C temperature coefficient, enabling predictable drift compensation in analog references. Its 200 Ω dynamic impedance at 250 mA test current supports stable regulation across load variations within its 500 mW power envelope.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4104US | Same 10.0 V Zener voltage, DO-213AA surface-mount package, RoHS-compliant, commercial-grade only | Lacks MIL qualification; not suitable for JANTX-requiring programs; requires PCB rework for SMT layout | Select when space-constrained layouts demand SMT and military screening is unnecessary |
| JAN1N4104-1 | Identical electrical specs and DO-35 package, but qualified only to JAN level (less stringent screening than JANTX) | Lower cost and shorter lead time, but excluded from programs mandating JANTX-level reliability documentation | Select when full JANTX screening is not contractually required but DO-35 form factor and 10 V regulation are essential |

FAQ
What is the Zener voltage tolerance of JANTX1N4104-1?
JANTX1N4104-1 has a nominal Zener voltage of 10.0 V with a ±5% tolerance, as defined by JEDEC standard and confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This tolerance applies at 250 mA test current and 25 °C ambient temperature, and is consistent across all JANTX-level units in the 1N4099–1N4135 series.
Is JANTX1N4104-1 suitable for high-temperature operation?
Yes, JANTX1N4104-1 is rated for junction and storage temperatures from -65 to +175 °C, with linear power derating beginning at 50 °C. Its 250 °C/W junction-to-lead thermal resistance (measured at 10 mm lead length) supports reliable operation in engine bay, avionics bay, and downhole electronics where ambient temperatures exceed 125 °C.
Does JANTX1N4104-1 require special ESD handling?
No, JANTX1N4104-1 is non-sensitive to ESD per MIL-STD-750 method 1020. Its metallurgically bonded structure and hermetic DO-35 package eliminate the need for ESD-protective workstations or packaging during standard assembly - unlike many modern silicon Zeners that require Class 1A handling.
What is the maximum Zener current IZM for JANTX1N4104-1?
The maximum Zener current IZM for JANTX1N4104-1 is 40 mA, as specified in the Electrical Characteristics table. This value corresponds to the current at which the device reaches its 500 mW power limit at 10.0 V, and must be respected to avoid thermal runaway or parametric shift during continuous operation.
How does the temperature coefficient affect JANTX1N4104-1 in precision reference designs?
JANTX1N4104-1 has a +0.080 %/°C temperature coefficient, meaning its Zener voltage increases by approximately 8 mV per °C rise above 25 °C. In precision reference designs, this predictable drift allows for first-order compensation using matched resistors or thermistors, especially in systems operating across -55 to +125 °C military temperature ranges.
