For engineers reviewing the JANTX1N4625C-1 datasheet, JANTX1N4625C-1 pinout, JANTX1N4625C-1 application, or JANTX1N4625C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), noise density (2 µV/√Hz), dynamic impedance (1500 Ω), temperature coefficient (−0.045/+0.030 %/°C), and military-grade reliability qualification.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 5.1 V at 250 mA test current, exhibiting low noise density (2 µV/√Hz) and stable regulation across −65 °C to +175 °C junction temperature range.
Its metallurgical bond construction ensures hermetic sealing and radiation hardness per Microsemi MicroNote 050, while its DO-35 axial-leaded package supports flexible through-hole mounting and meets MIL-STD-750 solderability requirements.

FAQ
What is the Zener voltage tolerance of JANTX1N4625C-1?
JANTX1N4625C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its nomenclature. This means its nominal 5.1 V Zener voltage is guaranteed between 4.998 V and 5.202 V at IZT = 250 mA and TA = 25 °C. The tighter tolerance reduces calibration overhead in precision reference designs compared to standard ±5% variants like JANTX1N4625-1.
Is JANTX1N4625C-1 suitable for high-temperature operation?
Yes, JANTX1N4625C-1 is rated for junction temperatures from −65 °C to +175 °C and features linear power derating from 500 mW at 25 °C to zero at 175 °C. Its metallurgically bonded DO-35 package maintains hermetic integrity under thermal cycling, making it suitable for engine-mounted avionics and downhole drilling electronics where sustained high-temperature operation is required.
Does JANTX1N4625C-1 meet RoHS requirements?
No, JANTX1N4625C-1 is not RoHS compliant. Per the nomenclature table, the "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions-not JAN/JANTX-qualified parts. JANTX1N4625C-1 uses traditional tin-lead plating per MIL-STD-750 Method 2026 and is intended for applications where military reliability takes precedence over lead-free mandates.
What is the maximum Zener current rating for JANTX1N4625C-1?
The maximum Zener current (IZM) for JANTX1N4625C-1 is 70.0 mA, derived from its 500 mW power rating and 5.1 V Zener voltage (P = V × I). This value assumes thermal equilibrium at TL = 25 °C; actual usable current must be reduced per the linear derating curve in Figure 2 when lead temperature exceeds 50 °C.
How does the noise performance of JANTX1N4625C-1 compare to lower-voltage Zeners in the same family?
JANTX1N4625C-1 exhibits 2 µV/√Hz noise density at IZT = 250 mA, consistent with the trend for 5–6 V Zeners in the 1N46xx series. Lower-voltage devices (e.g., 1N4614-1 at 1.8 V) show higher noise (1 µV/√Hz), while higher-voltage units (e.g., 1N4135-1 at 100 V) reach up to 40 µV/√Hz. Thus, JANTX1N4625C-1 delivers optimal noise-to-voltage ratio for general-purpose 5 V reference use.
