Product details
Overview
JANTX1N4133C-1/TR from Microsemi is a 500 mW, 87 V Zener voltage regulator diode in DO-35 glass package with 2% tolerance, metallurgically bonded construction, and MIL-PRF-19500/435 JANTX qualification for high-reliability aerospace and defense power regulation.
For engineers reviewing the JANTX1N4133C-1/TR datasheet, JANTX1N4133C-1/TR pinout, JANTX1N4133C-1/TR application, or JANTX1N4133C-1/TR equivalent, key selection criteria include Zener voltage (87 V), test current (250 mA), dynamic impedance (1000 Ω), noise density (1 µV/√Hz), and thermal resistance (250 °C/W) under lead-length-defined conditions.
Technical Context
This device operates as a precision shunt voltage reference in reverse-biased breakdown mode, with cathode band marking polarity and specified regulation at IZT = 250 mA. Its metallurgical bond ensures stable junction behavior across temperature extremes from –65 °C to +175 °C.
It delivers low-noise regulation (1 µV/√Hz) and exhibits a positive temperature coefficient of +0.100 %/°C, enabling predictable drift compensation in analog power supply feedback loops and reference circuits requiring long-term stability under thermal stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 87 V at 250 mA - defines precise regulation point for high-voltage reference and overvoltage clamp circuits |
| Power Dissipation | 500 mW at 25 °C - sets maximum continuous DC power handling before thermal derating begins at 50 °C |
| Zener Impedance ZZT | 1000 Ω - indicates voltage regulation sensitivity to load current changes; lower values improve regulation accuracy |
| Noise Density | 1 µV/√Hz - enables use in low-noise analog references where spectral purity affects ADC reference stability |
| Temp Coefficient αVZ | +0.100 %/°C - quantifies predictable voltage drift with temperature, critical for compensated reference designs |
| Reverse Leakage IR | 10 nA @ 69.6 V - ensures minimal parasitic current in high-impedance bias networks and sensing paths |
| Thermal Resistance RθJL | 250 °C/W @ 10 mm lead length - determines junction temperature rise above lead temperature during operation |
Pinout & Package
DO-35 (DO-204AH) axial-leaded hermetically sealed glass package; cathode identified by single black band; leads tinned or RoHS-compliant matte tin (commercial only); weight ≈ 0.2 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or lowest potential point in shunt regulator configuration |
| Cathode | Zener regulation output | Banded end; supplies regulated 87 V when reverse-biased; must be held at higher potential than anode |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 JANTX qualification | Validated reliability for aerospace and defense applications with full traceability and screening per military standards |
| Metallurgical bond construction | Eliminates interfacial delamination risk under thermal cycling, ensuring long-term parameter stability in harsh environments |
| 2% Zener voltage tolerance (C suffix) | Reduces calibration overhead in precision reference designs versus standard 5% parts, lowering system-level trimming requirements |
| Low 1 µV/√Hz noise density | Supports high-resolution data acquisition systems where reference noise directly limits effective number of bits (ENOB) |
| Hermetic glass DO-35 package | Provides moisture and contaminant immunity essential for mission-critical systems operating beyond 10-year service life |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4133US-1 | Same 87 V, 2% tolerance, but in surface-mount DO-213AA package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or wire-wrap | Select when board space is constrained and automated placement is available |
| JAN1N4133C-1 | Identical electrical specs and DO-35 package, but qualified only to JAN level (less stringent screening than JANTX) | Lacks extended burn-in and environmental stress screening required for flight hardware | Select for cost-sensitive ground-test or non-flight subsystems where full JANTX screening is unnecessary |
Compared with JANTX1N4133C-1/TR, the 1N4133US-1 offers identical regulation performance in a compact SMT form factor but eliminates axial mounting flexibility, while the JAN1N4133C-1 reduces procurement cost and lead time at the expense of radiation hardness and long-duration reliability validation.

FAQ
What is the Zener voltage tolerance of JANTX1N4133C-1/TR?
JANTX1N4133C-1/TR has a nominal Zener voltage of 87 V with a 2% tolerance, indicated by the "C" suffix in its part number. This means the actual VZ falls within 85.26 V to 88.74 V at 250 mA test current and 25 °C ambient, verified per MIL-PRF-19500/435 screening.
Is JANTX1N4133C-1/TR suitable for high-temperature operation?
Yes, JANTX1N4133C-1/TR is rated for junction and storage temperatures from –65 °C to +175 °C and is qualified to MIL-PRF-19500/435 JANTX level. Its metallurgically bonded construction ensures stable regulation performance across this full range without parameter shift or failure.
What does the "TR" suffix mean in JANTX1N4133C-1/TR?
"TR" denotes tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JANTX1N4133C-1/TR is supplied in reels for volume production, with the same electrical and reliability specifications as the bulk version JANTX1N4133C-1.
How does the noise performance of JANTX1N4133C-1/TR compare to lower-voltage Zeners?
JANTX1N4133C-1/TR exhibits 1 µV/√Hz noise density at 250 mA, consistent with the trend for high-voltage Zeners (>6.8 V) in this family. Lower-voltage variants (e.g., 5.1 V) show higher noise (e.g., 40 µV/√Hz), making JANTX1N4133C-1/TR preferable for low-noise high-voltage reference applications.
Can JANTX1N4133C-1/TR be used in place of commercial-grade 1N4133C-1?
No - JANTX1N4133C-1/TR is screened to military JANTX reliability standards including extended burn-in, temperature cycling, and hermeticity testing, whereas commercial 1N4133C-1 lacks these qualifications. Substitution requires full requalification per system-level reliability requirements.
