FAQ
What is the Zener voltage tolerance of JAN1N4134C-1?
JAN1N4134C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This corresponds to a 91 V nominal Zener voltage ranging from 89.18 V to 92.82 V at 250 mA test current and 25 °C ambient, supporting tighter regulation than standard ±5% variants in critical feedback paths.
Is JAN1N4134C-1 qualified to MIL-PRF-19500/435?
Yes, JAN1N4134C-1 is qualified to MIL-PRF-19500/435 at the JAN reliability level, including screening tests such as temperature cycling, steady-state life, and electrical verification. This qualification is documented in Microsemi's T4-LDS-0245-2 datasheet and confirms suitability for high-reliability defense and aerospace applications.
What is the maximum Zener current (IZM) for JAN1N4134C-1?
The maximum Zener current IZM for JAN1N4134C-1 is 69.2 mA, calculated from its 500 mW power rating and 91 V Zener voltage (P = V × I). This value is specified in the Electrical Characteristics table on page 3 of the official datasheet and defines the upper limit for continuous DC operation without exceeding thermal limits.
Does JAN1N4134C-1 have radiation hardness?
Yes, JAN1N4134C-1 is inherently radiation hard as described in Microsemi MicroNote 050. Its metallurgically bonded glass construction and DO-35 hermetic package provide tolerance to total ionizing dose (TID) and single-event effects (SEE), making it suitable for use in low-earth orbit and tactical nuclear environments without additional shielding.
What is the noise density specification for JAN1N4134C-1?
JAN1N4134C-1 has a maximum noise density of 1 µV/√Hz, consistent with the "1" entry in the ND column for 1N4134-1 in the Electrical Characteristics table. This low noise performance is achieved due to its metallurgical bond structure and applies at 250 mA Zener test current and 25 °C ambient, supporting high-precision analog reference design.
