Product details
Overview
JANTXV1N4125D-1/TR from Microsemi is a 47 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace power conditioning circuits.
For engineers reviewing the JANTXV1N4125D-1/TR datasheet, JANTXV1N4125D-1/TR pinout, JANTXV1N4125D-1/TR application, or JANTXV1N4125D-1/TR equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (≤40 µV/√Hz), radiation-hardened construction, and military-grade thermal derating behavior up to +175 °C junction temperature.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 47 V at 250 mA test current, exhibiting a dynamic impedance of 250 Ω and temperature coefficient of +0.095 %/°C. Its metallurgical bond ensures stable breakdown characteristics under thermal cycling and radiation exposure.
The DO-35 axial-leaded glass package provides hermetic sealing and supports operation across -65 °C to +175 °C junction temperature range, with thermal resistance junction-to-lead rated at 250 °C/W at 10 mm lead length - critical for high-reliability analog reference and biasing applications in avionics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 47 V ±1% at 250 mA - enables precise 47 V rail stabilization with minimal calibration drift. |
| Power Dissipation | 500 mW at 25 °C, linearly derated to zero at 175 °C - defines maximum continuous bias current in high-temp environments. |
| Dynamic Impedance ZZT | 250 Ω at 250 mA - determines output voltage variation under load transients in regulated supplies. |
| Noise Density | ≤40 µV/√Hz - ensures low-noise performance in precision reference and sensor excitation circuits. |
| Temp Coefficient αVZ | +0.095 %/°C - quantifies voltage drift over temperature; used to calculate worst-case regulation error in wide-range systems. |
| Reverse Leakage IR | ≤10 µA at 37.6 V - confirms tight regulation knee and low standby power loss in high-impedance bias networks. |
| Junction Temp Range | -65 °C to +175 °C - validates suitability for space-grade and engine-mounted electronics without derating penalties. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package with cathode indicated by band; operated with banded end positive relative to anode for Zener regulation. Hermetically sealed, tin-lead or RoHS-compliant matte-tin plating, solderable per MIL-STD-750 method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or lowest potential point; establishes return path for Zener current. |
| Cathode | Regulated output node | Banded terminal; supplies stable 47 V reference when reverse-biased above breakdown threshold. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 JANTXV qualification | Validates reliability for flight-critical systems with full lot traceability and screening per military standards. |
| Metallurgical bond construction | Eliminates interfacial delamination risk under thermal shock and radiation, ensuring long-term parameter stability. |
| 1% Zener voltage tolerance | Reduces need for post-assembly trimming in precision analog subsystems such as ADC references and op-amp biasing. |
| Low capacitance (typ. <2 pF) | Minimizes high-frequency loading on sensitive oscillator or RF detector nodes where Zener is used for clamping. |
| Radiation hardness | Inherently tolerant to total ionizing dose (TID) per Microsemi MicroNote 050 - suitable for low-earth orbit missions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4125US-1 | Same 47 V, 1% Zener voltage but in DO-213AA surface-mount package; no axial leads. | Used where board space is constrained and reflow assembly is required instead of through-hole mounting. | Select when automated SMT placement is needed and thermal pad layout supports 250 °C/W junction-to-lead dissipation. |
| 1N4125UR-1 | Commercial-grade version (non-military); same electrical specs but only JAN/JANTX qualified, not JANTXV. | Applicable in non-safety-critical industrial equipment where MIL-spec screening and traceability are not mandated. | Choose for cost-sensitive prototyping or commercial avionics subsystems lacking flight certification requirements. |
Compared with JANTXV1N4125D-1/TR, JANTXV1N4125US-1 offers identical regulation performance in surface-mount form factor but requires PCB redesign, while 1N4125UR-1 reduces cost and lead time at the expense of radiation hardness and extended temperature screening.
