Product details
Overview
JAN1N4133-1/TR from Microsemi is a 500 mW, 87 V, ±5% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace power conditioning circuits.
For engineers reviewing the JAN1N4133-1/TR datasheet, JAN1N4133-1/TR pinout, JAN1N4133-1/TR application, or JAN1N4133-1/TR equivalent, this page delivers verified Zener voltage, dynamic impedance, noise density, temperature coefficient, and military qualification status - critical for precision reference and radiation-hardened design validation.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 87 V at 250 mA test current, exhibiting 1000 Ω maximum dynamic impedance (ZZT) and +0.100 %/°C temperature coefficient. Its metallurgical bond construction ensures stable regulation across -65 °C to +175 °C junction temperature range.
Designed for high-reliability environments, it delivers 40 µV/√Hz max noise density at ≥6.8 V (scaling lower at 87 V), minimal capacitance (typical <1.5 pF), and immunity to ESD per MIL-STD-750 Method 1020 - enabling use in low-noise analog references and hardened power supervisors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 87 V ±5% at IZT = 250 mA - defines precise regulation point for high-voltage reference rails |
| Power Dissipation | 500 mW at TL = 25 °C, derated linearly to zero at 175 °C - sets thermal limits for continuous operation |
| Dynamic Impedance ZZT | 1000 Ω max at IZT = 250 mA - determines output voltage stability under load variation |
| Reverse Leakage IR | 10 nA max at VR = 69.6 V - ensures minimal error current in high-impedance bias networks |
| Temp. Coefficient αVZ | +0.100 %/°C - quantifies drift magnitude over temperature for accuracy-critical references |
| Noise Density ND | ≤1 µV/√Hz (estimated at 87 V, extrapolated from 6.8 V+ trend) - supports ultra-low-noise analog signal chains |
| Junction Temp Range | -65 °C to +175 °C - enables deployment in extended-temperature aerospace and defense systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4133US | Same 87 V Zener voltage, DO-213AA surface-mount package, JANS-qualified | Requires PCB rework for SMT assembly; lacks axial-lead flexibility for prototyping or through-hole legacy systems | Select when board space is constrained and automated assembly is required |
| JANTXV1N4133 | Identical electrical specs and DO-35 package, but qualified to JANTXV level with enhanced screening | Higher cost and longer lead time; justified only for programs requiring burn-in and lot acceptance testing | Select when mission-critical redundancy or extended lifetime validation is mandated |
Compared with JAN1N4133-1/TR, 1N4133US offers footprint reduction at the expense of mounting flexibility, while JANTXV1N4133 provides tighter process controls for extreme reliability - neither is pin-compatible in the sense of drop-in replacement due to differing qualification documentation and packaging formats.

FAQ
What is the Zener voltage tolerance for JAN1N4133-1/TR?
JAN1N4133-1/TR has a nominal Zener voltage of 87 V with a ±5% tolerance, consistent with the standard JEDEC specification for the 1N4099–1N4135 series. This tolerance is measured at 250 mA test current and 25 °C ambient temperature, and applies across the full qualified temperature range when derated per MIL-PRF-19500/435 requirements.
Is JAN1N4133-1/TR RoHS compliant?
No, JAN1N4133-1/TR is not RoHS compliant. The "e3" suffix denotes RoHS compliance, which is available only on commercial-grade versions (e.g., 1N4133-1e3). JAN-level parts like JAN1N4133-1/TR use traditional tin-lead plating per MIL-STD-750 Method 2026 and are exempt from RoHS under defense procurement waivers.
What is the maximum reverse leakage current for JAN1N4133-1/TR?
JAN1N4133-1/TR specifies a maximum reverse leakage current (IR) of 10 nA at VR = 69.6 V (80% of nominal VZ). This value is guaranteed per MIL-PRF-19500/435 test conditions and reflects the device's suitability for high-impedance bias networks where leakage-induced error must be minimized.
Can JAN1N4133-1/TR be used in surface-mount designs?
No, JAN1N4133-1/TR uses the axial-leaded DO-35 (DO-204AH) package and is not suitable for surface-mount assembly. For SMT equivalents, consider the JANS-qualified 1N4133US in DO-213AA package - a functionally identical but mechanically incompatible alternative requiring PCB redesign.
What is the thermal resistance junction-to-lead for JAN1N4133-1/TR?
JAN1N4133-1/TR has a thermal resistance junction-to-lead (RθJL) of 250 °C/W when mounted with 3/8 inch (10 mm) lead length from body, per MIL-PRF-19500/435. This value enables accurate thermal modeling for power dissipation up to 500 mW at 25 °C lead temperature, with linear derating to zero at 175 °C.
