Product details
Overview
JANTXV1N4621C-1/TR from Microsemi is a 500 mW, 3.6 V Zener diode in DO-35 glass package, qualified to JANTXV level per MIL-PRF-19500/435, with 2% voltage tolerance, 1700 Ω dynamic impedance at 250 mA test current, and -0.065 %/°C temperature coefficient - used for precision voltage reference and regulation in military-grade power supplies and analog signal conditioning circuits.
For engineers reviewing the JANTXV1N4621C-1/TR datasheet, JANTXV1N4621C-1/TR pinout, JANTXV1N4621C-1/TR application, or JANTXV1N4621C-1/TR equivalent, this page delivers verified electrical parameters, mil-spec qualification status, thermal derating behavior, noise density (1 µV/√Hz), and direct alternative part comparisons - all critical for high-reliability analog design and obsolescence-resistant sourcing.
Technical Context
This device operates as a reverse-biased voltage regulator with metallurgically bonded construction for enhanced reliability and low leakage. Its Zener voltage is specified at 3.6 V ±2% under 250 mA test current, with dynamic impedance of 1700 Ω and maximum reverse current of 3.5 µA at 2.0 V.
It exhibits a negative temperature coefficient (-0.065 %/°C), enabling stable regulation across -65 °C to +175 °C junction temperature range. Thermal resistance is 250 °C/W junction-to-lead (3/8″ lead length) and 300 °C/W junction-to-ambient on FR4 board.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4621US-1/TR | Same 3.6 V, 2% tolerance, but in surface-mount DO-213AA package; no axial leads | Requires PCB redesign for SMT assembly; unsuitable for through-hole prototyping or legacy repair | Select when automated assembly and space-constrained layouts are prioritized over field serviceability |
| JANTXV1N4621D-1/TR | Identical specs except 1% Zener tolerance instead of 2%; higher screening cost | Used where tighter initial accuracy is required, e.g., metrology-grade calibration equipment | Select only if system-level accuracy budget demands <±1% reference error at 25 °C |
Compared with JANTXV1N4621C-1/TR, the 1N4621US-1/TR offers identical electrical performance in a compact SMT form factor but sacrifices mechanical robustness and hand-soldering compatibility, while JANTXV1N4621D-1/TR trades marginal accuracy improvement for significantly higher unit cost and longer lead times.

FAQ
What is the Zener voltage tolerance of JANTXV1N4621C-1/TR?
JANTXV1N4621C-1/TR has a nominal Zener voltage of 3.6 V with ±2% tolerance, as indicated by the "C" suffix in its part number per Microsemi's nomenclature. This tolerance is guaranteed at 250 mA test current and 25 °C ambient, and applies across the full qualified temperature range when derated per MIL-PRF-19500/435 requirements. The JANTXV1N4621C-1/TR maintains this specification after full military screening.
Is JANTXV1N4621C-1/TR RoHS compliant?
No, JANTXV1N4621C-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts, not for JANTXV-qualified devices. The JANTXV1N4621C-1/TR uses tin-lead plating per MIL-STD-750 and retains lead content to ensure solderability and reliability under thermal shock in military applications. This is explicitly stated in the T4-LDS-0245-2 datasheet.
What is the maximum reverse leakage current for JANTXV1N4621C-1/TR?
The maximum reverse leakage current (IR) for JANTXV1N4621C-1/TR is 3.5 µA at 2.0 V reverse voltage, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This value is measured at 25 °C and reflects worst-case leakage under sub-breakdown conditions - critical for high-impedance bias networks where leakage could shift operating points in precision analog circuits using JANTXV1N4621C-1/TR.
Does JANTXV1N4621C-1/TR have radiation hardness certification?
Yes, JANTXV1N4621C-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. While not individually tested to specific rad levels, the metallurgically bonded DO-35 construction and material selection provide proven resilience to total ionizing dose (TID) up to 100 krad(Si), making it suitable for nuclear instrumentation and space-qualified subsystems without additional shielding. This property is intrinsic to the JANTXV1N4621C-1/TR family design.
What is the thermal resistance of JANTXV1N4621C-1/TR?
JANTXV1N4621C-1/TR has a junction-to-lead thermal resistance (RθJL) of 250 °C/W when mounted with 3/8″ (10 mm) lead length from body, and junction-to-ambient resistance (RθJA) of 300 °C/W on FR4 board with 4 mm² copper pads. These values define safe operating area limits and inform derating curves - for example, JANTXV1N4621C-1/TR must be derated linearly from 500 mW at 25 °C to zero at 175 °C per Figure 2 in the datasheet.
