For engineers reviewing the JANTXV1N4132D-1 datasheet, JANTXV1N4132D-1 pinout, JANTXV1N4132D-1 application, or JANTXV1N4132D-1 equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (1 µV/√Hz), radiation hardness, hermetic glass packaging, and military-grade thermal derating performance up to +175 °C junction temperature.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 82.0 V at 250 mA test current, exhibiting a dynamic impedance of 800 Ω and maximum reverse leakage of 0.01 µA at 62.4 V. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and mechanical stress.
The JANTXV1N4132D-1 features a positive temperature coefficient of +0.100 %/°C and is rated for operation from –65 °C to +175 °C. It delivers low capacitance (typical <1.5 pF per Figure 3) and minimal noise-critical for reference stability in analog signal chains and precision power monitoring circuits.

FAQ
What is the Zener voltage tolerance of JANTXV1N4132D-1?
JANTXV1N4132D-1 has a Zener voltage tolerance of ±1%, indicated by the "D" suffix in its nomenclature. This means its nominal 82.0 V Zener voltage is guaranteed between 81.18 V and 82.82 V at 250 mA test current and 25 °C ambient, supporting high-accuracy reference designs without post-manufacture trimming.
Is JANTXV1N4132D-1 radiation hardened?
Yes, JANTXV1N4132D-1 is inherently radiation hard as documented in Microsemi MicroNote 050. It is qualified per MIL-PRF-19500/435 JANTXV level and exhibits proven resilience to total ionizing dose (TID), making it suitable for use in low-earth orbit satellite power systems and nuclear instrumentation where radiation exposure is expected.
What is the maximum junction temperature rating for JANTXV1N4132D-1?
JANTXV1N4132D-1 is rated for a junction and storage temperature range of –65 °C to +175 °C. Its thermal resistance junction-to-lead is 250 °C/W at 3/8 inch lead length, enabling reliable operation in high-temperature avionics bays and engine-mounted electronics without active cooling.
Does JANTXV1N4132D-1 have low noise performance?
Yes, JANTXV1N4132D-1 delivers ultra-low noise density of 1 µV/√Hz at its 82 V Zener voltage, significantly lower than standard Zeners. This performance is confirmed in the manufacturer's noise density measurement circuit (Figure 1) and makes JANTXV1N4132D-1 ideal for precision analog references in ADCs and sensor signal chains.
What package type does JANTXV1N4132D-1 use?
JANTXV1N4132D-1 uses the DO-35 (also designated DO-204AH) axial-leaded, hermetically sealed glass package. The cathode is marked by a visible band on the glass body, and leads are tin-lead plated per MIL-STD-750 Method 2026 for reliable solderability in high-reliability assemblies.
