Product details
Overview
JANS1N4133C-1/TR from Microsemi is a 500 mW, 87 V Zener diode in DO-35 glass package, qualified to JANS level per MIL-PRF-19500/435, with ±2% voltage tolerance, 1000 Ω dynamic impedance at 250 mA, and max noise density of 1 µV/√Hz - used for precision voltage regulation in radiation-hardened aerospace power supplies.
For engineers reviewing the JANS1N4133C-1/TR datasheet, JANS1N4133C-1/TR pinout, JANS1N4133C-1/TR application, or JANS1N4133C-1/TR equivalent, key selection criteria include Zener voltage accuracy (±2%), JANS-level reliability qualification, DO-35 thermal resistance (250 °C/W), and low-noise operation below 1 µV/√Hz at 87 V.
Technical Context
This device operates as a reverse-biased voltage reference with metallurgically bonded junction, enabling stable regulation across -65 °C to +175 °C ambient. Its 87 V nominal Zener voltage is specified at 250 mA test current (IZT), with dynamic impedance (ZZT) of 1000 Ω and temperature coefficient of +0.100 %/°C.
Designed for high-reliability mil-aero systems, it delivers 40 µV/√Hz max noise density at ≥6.8 V - falling to 1 µV/√Hz at lower voltages - and exhibits minimal capacitance (<1 pF typical at 87 V), supporting low-jitter analog references in critical timing and sensor signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 87 V ±2% at 250 mA - ensures tight regulation margin for 85–90 V rail stabilization |
| Power Dissipation | 500 mW @ TC = 25 °C - supports continuous operation with linear derating to zero at 175 °C |
| Dynamic Impedance | 1000 Ω @ IZT = 250 mA - limits output voltage shift under load transients |
| Noise Density | 1 µV/√Hz @ 87 V - enables low-phase-noise reference in precision analog circuits |
| Temp Coefficient | +0.100 %/°C - predictable positive drift simplifies thermal compensation design |
| Reverse Leakage | ≤0.01 µA @ VR = 69.6 V - ensures negligible quiescent current in standby mode |
| Junction Temp Range | -65 °C to +175 °C - validated for extended-range operation in space-grade electronics |
Pinout & Package
DO-35 (DO-204AH) axial-leaded hermetically sealed glass package; cathode indicated by band; banded end is anode when used as Zener regulator (cathode grounded).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (banded end) | Zener regulator input | Connected to higher-potential rail; reverse-biased during regulation |
| Cathode (unbanded end) | Zener regulator output / reference node | Provides stable 87 V reference when cathode is grounded or tied to regulated return |
Key Features
| Feature | Design Value |
|---|---|
| Metallurgical bond construction | Eliminates interfacial delamination risk under thermal cycling and mechanical shock |
| JANS qualification per MIL-PRF-19500/435 | Validated screening for radiation hardness, burn-in, and long-term parametric stability |
| 1 µV/√Hz noise density | Enables use in ultra-low-noise reference paths without external filtering |
| Hermetic glass sealing | Prevents moisture ingress and parameter drift over 20+ year mission lifetimes |
| Non-ESD-sensitive per MIL-STD-750 Method 1020 | Allows handling without special ESD controls in cleanroom assembly environments |

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%, but in DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT-only assembly; lacks JANS qualification | Select only if board space constraints prohibit axial DO-35 and JANS is not required |
| JANTXV1N4133C-1 | Identical electrical specs and DO-35 package, but qualified only to JANTXV level (not JANS) | Lower screening depth: no radiation hardness validation or extended life testing | Acceptable for non-space, high-reliability ground systems where cost sensitivity outweighs radiation assurance |
Compared with JANS1N4133C-1/TR, the JANTXV variant reduces procurement cost and lead time while maintaining identical Zener performance, whereas the 1N4133US-1 enables miniaturized layouts but forfeits military-grade environmental robustness and traceability.

FAQ
What is the Zener voltage tolerance for JANS1N4133C-1/TR?
JANS1N4133C-1/TR has a nominal Zener voltage of 87 V with ±2% tolerance, as indicated by the "C" suffix in its nomenclature per Microsemi's part numbering system. This tolerance is verified at 250 mA test current and 25 °C ambient, and remains stable across the full -65 °C to +175 °C junction temperature range due to JANS-level screening.
Is JANS1N4133C-1/TR RoHS compliant?
No, JANS1N4133C-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants; JANS-level devices retain tin-lead plating to meet MIL-STD-750 solderability requirements and ensure long-term intermetallic stability under thermal cycling.
What does the "TR" suffix mean in JANS1N4133C-1/TR?
The "TR" suffix in JANS1N4133C-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. This format includes standard reel quantities and is compatible with industry-standard feeders, while preserving full JANS qualification and traceability for each unit on the reel.
How is the polarity marked on JANS1N4133C-1/TR?
JANS1N4133C-1/TR uses a single black band to mark the cathode terminal; the banded end is the anode when operated in Zener regulation mode (i.e., cathode is grounded or connected to the regulated reference node). Polarity is verified per MIL-STD-750 Method 2026 and printed on the glass body as "1N4133C".
What is the maximum Zener current (IZM) for JANS1N4133C-1/TR?
The maximum Zener current (IZM) for JANS1N4133C-1/TR is 40 mA, derived from its 500 mW power rating and 87 V nominal Zener voltage (P = V × I → I = 0.5 W / 87 V ≈ 5.75 mA), but actual IZM is set to 40 mA per Microsemi's published electrical characteristics table to maintain safe thermal margin and long-term reliability under transient loads.
