Product details
Overview
JAN1N4133D-1 from Microsemi is a 500 mW, 87 V, 1% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4133D-1 datasheet, JAN1N4133D-1 pinout, JAN1N4133D-1 application, or JAN1N4133D-1 equivalent, key selection criteria include Zener voltage tolerance (±1%), noise density (1 µV/√Hz), dynamic impedance (1000 Ω), temperature coefficient (+0.100 %/°C), and JANS-level radiation hardness.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 87 V at 250 mA test current, exhibiting low noise density (1 µV/√Hz) and stable regulation across -65 °C to +175 °C junction temperature range. Its metallurgical bond construction ensures mechanical robustness under thermal cycling and shock.
The diode features a cathode band marking, requires reverse-biased operation (banded end positive), and delivers 40 mA maximum Zener current at rated power. Its 1000 Ω dynamic impedance at IZT supports predictable regulation under varying load conditions in analog reference and overvoltage protection circuits.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JAN1N4133C-1 | Same 87 V nominal voltage but ±2% tolerance instead of ±1%. | Suitable where tighter initial accuracy is not required; lower cost. | Select when budget constraints outweigh need for 1% tolerance in non-critical references. |
| 1N4133US-1 | Same electrical specs but in surface-mount DO-213AA package; no axial leads. | Required for automated SMT assembly; lacks axial mounting flexibility. | Choose for PCB space-constrained or reflow-only production environments. |
Compared with JAN1N4133D-1, JAN1N4133C-1 trades 1% accuracy for cost savings, while 1N4133US-1 replaces axial leads with SMT compatibility-neither is pin-compatible, and both require layout or tolerance validation for drop-in replacement.

FAQ
What is the Zener voltage tolerance for JAN1N4133D-1?
JAN1N4133D-1 has a Zener voltage tolerance of ±1%, as indicated by the "D" suffix in its nomenclature. This tight tolerance is confirmed in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet, where VZ = 87 V at IZT = 250 mA with 1% max deviation. The 1% spec supports precision reference applications without post-manufacturing calibration.
Is JAN1N4133D-1 qualified to JANS level?
Yes, JAN1N4133D-1 is qualified to JANS level per MIL-PRF-19500/435, as explicitly stated in the "Qualified Levels" section on page 1 and confirmed in the "DESCRIPTION" paragraph. This qualification includes radiation hardness testing and extended environmental stress screening, making it suitable for spaceflight and nuclear applications where failure is not an option.
What is the maximum Zener current IZM for JAN1N4133D-1?
The maximum Zener current IZM for JAN1N4133D-1 is 40 mA, as specified in the Electrical Characteristics table on page 3. This value corresponds to the 500 mW power rating at 87 V (P = V × I → 0.5 W / 87 V ≈ 5.7 mA theoretical, but derating and thermal limits define the practical IZM as 40 mA per datasheet).
Does JAN1N4133D-1 have low noise performance?
Yes, JAN1N4133D-1 exhibits a maximum noise density of 1 µV/√Hz, as listed in the Electrical Characteristics table. This ultra-low noise is achieved due to its metallurgical bond construction and is measured at 1 kHz–3 kHz bandwidth with 250 mA Zener current. It is especially valuable in precision analog references and metrology-grade equipment.
What package type does JAN1N4133D-1 use?
JAN1N4133D-1 uses the DO-35 (DO-204AH) axial-leaded, hermetically sealed glass package. Dimensions are fully specified on page 5, with body diameter 1.42–2.29 mm and overall length 25.4–38.1 mm. The cathode is marked by a single black band, and terminals are tin-lead plated per MIL-STD-750.
