Product details
Overview
JANTXV1N4133C-1/TR from Microsemi is a 500 mW, 87 V, ±2% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4133C-1/TR datasheet, JANTXV1N4133C-1/TR pinout, JANTXV1N4133C-1/TR application, or JANTXV1N4133C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), noise density (1 µV/√Hz), max reverse current (10 nA @ 69.6 V), temperature coefficient (+0.100 %/°C), and JANTXV-level qualification for extended temperature operation (-65 °C to +175 °C).
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 87 V at 250 mA test current, featuring low dynamic impedance (1000 Ω) and minimal capacitance (typ. 2.5 pF). Its metallurgical bond construction ensures stable regulation across wide current ranges (0.25–40 mA) and thermal cycling.
The JANTXV1N4133C-1/TR exhibits a positive temperature coefficient of +0.100 %/°C above 6.8 V, enabling predictable voltage drift in high-temperature environments. It delivers 1 µV/√Hz noise density at 25 °C - among the lowest in the 1N41xx series - supporting low-noise reference applications in analog instrumentation and telemetry systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4133-1/TR | Same 87 V rating but ±5% tolerance (no C suffix); higher IR (10 nA vs. 10 nA same), identical noise density. | Suitable where calibration trim compensates for wider tolerance; not acceptable for closed-loop feedback without gain adjustment. | Select JANTXV1N4133C-1/TR when ±2% initial accuracy is required without external trimming. |
| JANS1N4133C-1/TR | Identical electrical specs and ±2% tolerance; qualified to JANS level with enhanced screening (e.g., 100% lot acceptance testing). | Required for space-grade programs demanding zero-defect reliability; adds cost and lead time vs. JANTXV. | Choose JANS1N4133C-1/TR only when mission-critical redundancy or radiation tolerance beyond JANTXV is mandated. |
Compared with JANTXV1N4133-1/TR, the JANTXV1N4133C-1/TR delivers tighter voltage control for untrimmed feedback loops, while JANS1N4133C-1/TR extends reliability assurance to full space qualification - making the JANTXV variant the optimal balance of precision and program affordability for high-reliability terrestrial and LEO applications.

FAQ
What is the Zener voltage tolerance of JANTXV1N4133C-1/TR?
The "C" suffix in JANTXV1N4133C-1/TR denotes a ±2% Zener voltage tolerance at 250 mA test current, verified per MIL-PRF-19500/435 screening. This is tighter than the standard ±5% (blank suffix) and enables direct use in untrimmed feedback networks without external calibration.
Is JANTXV1N4133C-1/TR suitable for high-temperature operation?
Yes - JANTXV1N4133C-1/TR is rated for junction temperatures from -65 °C to +175 °C and qualified to MIL-PRF-19500/435 JANTXV level, including thermal cycling and high-temperature life testing. Its metallurgical bond and hermetic DO-35 package ensure parametric stability across this full range.
What is the noise performance of JANTXV1N4133C-1/TR?
JANTXV1N4133C-1/TR delivers 1 µV/√Hz noise density at 25 °C, measured in the 1–3 kHz band per Figure 1 of T4-LDS-0245-2. This ultra-low noise supports precision reference applications in radar receivers and instrumentation where phase noise or ADC quantization error must be minimized.
How does the temperature coefficient affect JANTXV1N4133C-1/TR in practice?
JANTXV1N4133C-1/TR has a +0.100 %/°C temperature coefficient, meaning its Zener voltage increases by ~87 mV per °C rise above 25 °C. This predictable drift allows accurate software or hardware compensation in avionics systems where ambient temperature varies widely during flight profiles.
What packaging and plating options are available for JANTXV1N4133C-1/TR?
JANTXV1N4133C-1/TR uses the DO-35 (DO-204AH) axial-leaded glass package with cathode band marking. Leads are plated with tin-lead per MIL-STD-750 method 2026; RoHS-compliant matte-tin plating is available on commercial-grade versions only - JANTXV units retain legacy tin-lead finish for solderability assurance.
