Product details
Overview
JANTXV1N4134C-1 from Microsemi is a 500 mW, 91 V ±2% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4134C-1 datasheet, JANTXV1N4134C-1 pinout, JANTXV1N4134C-1 application, or JANTXV1N4134C-1 equivalent, key selection criteria include its 91 V nominal Zener voltage at 250 mA test current, 1200 Ω dynamic impedance, 40 µA maximum reverse leakage at 73 V, ±2% voltage tolerance, and radiation-hardened hermetic construction.
Technical Context
This device operates as a precision shunt voltage regulator with a specified Zener test current of 250 mA and exhibits a positive temperature coefficient of +0.100 %/°C above 50 V. Its internal metallurgical bond ensures stable breakdown characteristics under thermal cycling and mechanical stress.
Designed for high-reliability mil-spec applications, JANTXV1N4134C-1 maintains regulation across wide current ranges (IZK to IZM), delivers low noise density (≤1 µV/√Hz below 6.8 V), and features minimal junction capacitance - typical values fall below 2 pF per Figure 3 of the datasheet.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANS1N4134C-1 | Same electrical specs; qualified to JANS (highest reliability level) with full lot traceability and extended screening | Required for Class S spaceflight hardware; not needed for ground-based JANTXV-tier systems | Select when full MIL-PRF-19500/435 JANS compliance and radiation assurance documentation are mandatory |
| 1N4134C-1 (commercial) | Identical Zener voltage, tolerance, and package; lacks MIL qualification and radiation hardening | Suitable only for non-critical industrial or lab-use applications; not rated for aerospace deployment | Select for cost-sensitive prototyping or non-mil environments where reliability testing is not required |
Compared with JANTXV1N4134C-1, JANS1N4134C-1 adds full space-level screening and traceability at higher cost, while 1N4134C-1 omits all military qualifications - making JANTXV1N4134C-1 the optimal balance of assured reliability and procurement flexibility for defense-grade programs.

FAQ
What is the Zener voltage tolerance of JANTXV1N4134C-1?
JANTXV1N4134C-1 has a nominal Zener voltage of 91 V with a ±2% tolerance, as indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, and applies across the full qualified operating temperature range of -65 to +175 °C.
Is JANTXV1N4134C-1 RoHS compliant?
No, JANTXV1N4134C-1 is not RoHS compliant. Per the datasheet, RoHS-compliant versions (suffix "e3") are available only for commercial-grade parts (blank reliability level), not for JAN, JANTX, JANTXV, or JANS variants. JANTXV1N4134C-1 uses traditional tin-lead plating per MIL-STD-750.
What is the maximum Zener current IZM for JANTXV1N4134C-1?
The maximum Zener current IZM for JANTXV1N4134C-1 is 69.2 mA, derived from its 500 mW power rating and 91 V Zener voltage (P = V × I → I = 0.5 W / 91 V ≈ 69.2 mA). This value is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1.
Does JANTXV1N4134C-1 have radiation hardness certification?
Yes, JANTXV1N4134C-1 is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded structure and hermetic DO-35 package provide proven resistance to total ionizing dose (TID), making it suitable for use in radiation-prone environments such as space and nuclear facilities.
What is the thermal resistance junction-to-lead for JANTXV1N4134C-1?
The thermal resistance junction-to-lead (RθJL) for JANTXV1N4134C-1 is 250 °C/W, measured with 3/8 inch (10 mm) lead length from the body. This value is specified in the Maximum Ratings table on page 1 of the datasheet and informs heatsinking requirements for sustained 500 mW operation.
