Product details
Overview
JAN1N4105-1/TR from Microsemi is a 500 mW, 11.0 V Zener voltage regulator diode in DO-35 glass axial-leaded package, qualified to JAN reliability level per MIL-PRF-19500/435, with 5% voltage tolerance, 250 mA test current, and 200 Ω dynamic impedance at 25 °C - used for precision voltage reference and regulation in military-grade power supply monitoring circuits.
For engineers reviewing the JAN1N4105-1/TR datasheet, JAN1N4105-1/TR pinout, JAN1N4105-1/TR application, or JAN1N4105-1/TR equivalent, key selection criteria include Zener voltage stability over temperature (αVZ = +0.080 %/°C), low reverse leakage (IR ≤ 0.05 µA @ VR = 8.5 V), noise density (ND = 1 µV/√Hz), and hermetic DO-35 packaging for high-reliability environments.
Technical Context
This device operates as a reverse-biased Zener regulator with metallurgically bonded junction, delivering stable 11.0 V reference across 250 mA test current and full rated power (500 mW) at TC = 25 °C. Its thermal resistance junction-to-lead is 250 °C/W with 3/8″ lead length, enabling reliable operation up to TJ = +175 °C.
The diode exhibits low capacitance (typical <2 pF at 0 V), minimal noise density (1 µV/√Hz), and zero ESD sensitivity per MIL-STD-750 Method 1020. It is polarity-marked with cathode band and requires banded end to be positive for regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 11.0 V at IZT = 250 mA - defines precise regulation point under standard test conditions |
| Power Dissipation PM(AV) | 500 mW at TC = 25 °C - sets maximum continuous thermal load before derating begins at TL ≥ 50 °C |
| Zener Impedance ZZT | 200 Ω at IZT = 250 mA - determines output voltage variation under load current changes |
| Reverse Leakage IR | ≤ 0.05 µA at VR = 8.5 V - ensures minimal standby current in high-impedance bias networks |
| Temp Coefficient αVZ | +0.080 %/°C - quantifies voltage drift over operating temperature range (-65 to +175 °C) |
| Noise Density ND | 1 µV/√Hz at IZT = 250 mA - supports low-noise analog references in precision instrumentation |
| Junction Temp Range | -65 to +175 °C - enables deployment in extreme aerospace and defense environmental profiles |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4105US-1 | Same electrical specs but in DO-213AA surface-mount package | Requires PCB rework for SMT assembly; no axial through-hole mounting | Select when automated assembly and space-constrained layouts are prioritized over manual repairability |
| JANTXV1N4105-1 | Identical DO-35 package and Zener parameters, but qualified to JANTXV level with enhanced screening | Supports higher assurance programs requiring burn-in, lot acceptance testing, and radiation hardness data | Select when mission-critical systems demand extended reliability validation beyond JAN level |
Compared with JAN1N4105-1/TR, 1N4105US-1 offers identical regulation performance in a surface-mount form factor, while JANTXV1N4105-1 provides stricter process controls and test coverage - both require explicit validation for drop-in replacement due to differing qualification scope and packaging.

FAQ
What is the Zener voltage and tolerance of JAN1N4105-1/TR?
JAN1N4105-1/TR has a nominal Zener voltage of 11.0 V with ±5% tolerance at IZT = 250 mA and 25 °C. This tolerance is standard for the JAN-level version per JEDEC registration and MIL-PRF-19500/435 compliance. The device maintains regulation within this band across its full operating temperature range (-65 to +175 °C), supported by a temperature coefficient of +0.080 %/°C.
Is JAN1N4105-1/TR RoHS compliant?
No, JAN1N4105-1/TR is not RoHS compliant. RoHS-compliant versions (e.g., with e3 suffix) are available only for commercial-grade variants per the datasheet. The JAN-level qualification requires tin-lead plating for solderability and reliability validation under MIL-STD-750 Method 2026, which is incompatible with RoHS restrictions.
What is the maximum reverse leakage current for JAN1N4105-1/TR?
The maximum reverse leakage current (IR) for JAN1N4105-1/TR is 0.05 µA at VR = 8.5 V and 25 °C. This ultra-low leakage supports high-impedance bias networks and precision reference divider chains where current draw must remain negligible - critical in battery-powered or low-power defense subsystems.
Can JAN1N4105-1/TR be used in surface-mount designs?
No, JAN1N4105-1/TR uses a DO-35 axial-leaded glass package intended for through-hole mounting. For surface-mount equivalents, Microsemi offers the 1N4105US-1 in DO-213AA package. Substituting JAN1N4105-1/TR into SMT layouts would require mechanical adaptation and is not recommended without full requalification.
What is the thermal resistance specification for JAN1N4105-1/TR?
JAN1N4105-1/TR has a thermal resistance junction-to-lead (RθJL) of 250 °C/W when measured with 3/8″ (10 mm) lead length from the body. This value assumes standard FR4 PCB mounting per datasheet test condition and enables accurate power derating calculations - for example, full 500 mW operation is permitted up to TL = 50 °C, then linearly derated to zero at 175 °C.
