Product details
Overview
1N6024UR/TR from Microsemi is a surface-mount 100 V, 500 mW Zener diode in DO-213AA (MLL34) MELF package with ±5% voltage tolerance, 1.0 mA maximum reverse leakage at 76 V, and +0.110 %/°C temperature coefficient - used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the 1N6024UR/TR datasheet, 1N6024UR/TR pinout, 1N6024UR/TR application, or 1N6024UR/TR equivalent, this page delivers verified electrical parameters, thermal derating behavior, RoHS-compliant packaging details, and direct alternatives for industrial power management designs requiring stable 100 V reference regulation.
Technical Context
This Zener diode operates in reverse breakdown with a nominal Zener voltage of 100 V at 1.0 mA test current (IZT), exhibiting dynamic impedance of 2600 Ω at IZT and 4000 Ω near the knee (IZK = 0.25 mA). Its positive temperature coefficient (+0.110 %/°C) ensures predictable voltage drift across operating temperatures.
Designed for surface-mount assembly on FR4 PCBs with 1 oz copper, it features hermetically sealed glass construction, metallurgical bonding, and end-cap solderability per MIL-STD-750 Method 2026 - supporting high-reliability commercial and screened military applications per MIL-PRF-19500.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage (VZ) | 100 V at 1.0 mA - defines precise regulation point for feedback networks and clamp thresholds. |
| Power Dissipation (PD) | 0.5 W at 25 °C - sets maximum continuous power handling before thermal derating applies. |
| Zener Impedance (ZZT) | 2600 Ω at 1.0 mA - indicates regulation stability under small-signal AC modulation. |
| Reverse Leakage Current (IR) | 0.1 µA max at 76 V - ensures minimal standby current in high-impedance bias or sensing paths. |
| Temperature Coefficient (αVZ) | +0.110 %/°C - quantifies voltage drift magnitude per degree Celsius rise in junction temperature. |
| Junction Temperature Range | –65 to +175 °C - enables operation in extended industrial and aerospace environments. |
| Package Type | DO-213AA (MLL34) - cylindrical MELF glass package optimized for automated placement and thermal reliability. |
Pinout & Package
DO-213AA (MLL34) is a two-terminal hermetically sealed glass MELF package with tin-lead or RoHS-compliant matte-tin end-cap plating. Polarity is marked by a cathode band; the banded end is positive during Zener operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Regulated output node | Connected to higher-potential side of load; establishes reference voltage relative to anode. |
| Anode (unbanded end) | Reference/return node | Typically tied to system ground or lower-voltage rail; completes Zener conduction path. |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass MELF construction | Enables long-term stability and moisture resistance without conformal coating in harsh environments. |
| Metallurgically bonded terminals | Ensures low-contact-resistance interfaces and robust thermal transfer from junction to end caps. |
| RoHS-compliant option (e3 suffix) | Meets EU environmental compliance for commercial-grade assemblies without lead content restrictions. |
| ESD insensitivity (MIL-STD-750 Method 1020) | Eliminates need for ESD handling protocols during board assembly and testing. |
| Radiation-hardened design | Validated per Microsemi MicroNote 050 for total ionizing dose tolerance in space and nuclear applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6024UR-1 | Tape-and-reel delivery omitted; same electrical specs and DO-213AA package. | Preferred for manual prototyping or low-volume hand-soldering where reel logistics are unnecessary. | Select 1N6024UR-1 when tape-and-reel automation is not required and cost optimization is prioritized. |
| BZX85C100 | DO-41 axial package (not surface-mount); 100 V ±5%, 1.3 W rating; higher power but larger footprint. | Suitable for through-hole legacy designs or higher-power dissipation needs where board space permits. | Choose BZX85C100 only if axial mounting is acceptable and >0.5 W dissipation is needed - not a drop-in replacement. |
Compared with 1N6024UR/TR, the 1N6024UR-1 offers identical performance without tape-and-reel convenience, while BZX85C100 trades surface-mount compatibility for higher power and through-hole fit - making 1N6024UR/TR optimal for compact, automated, high-reliability SMT power regulation.

FAQ
What is the Zener voltage tolerance of the 1N6024UR/TR?
The 1N6024UR/TR has a nominal Zener voltage of 100 V with a ±5% tolerance, meaning its actual regulation voltage falls between 95 V and 105 V when tested at 1.0 mA. This tolerance is indicated by the "B" suffix in the part nomenclature and is confirmed in the Electrical Characteristics table on page 3 of the T4-LDS-0228-1 datasheet.
Does the 1N6024UR/TR meet RoHS requirements?
Yes, the 1N6024UR/TR is RoHS compliant (e3 suffix), with matte-tin end-cap plating and no lead content. RoHS compliance applies only to commercial-grade versions; military-screened variants use tin-lead plating and are not RoHS compliant.
What is the maximum reverse leakage current for the 1N6024UR/TR?
The 1N6024UR/TR specifies a maximum reverse leakage current (IR) of 0.1 µA at 76 V, measured at 30 °C lead temperature. This ultra-low leakage supports high-impedance bias networks and precision reference applications where standby current must be minimized.
Can the 1N6024UR/TR be used in high-temperature environments?
Yes, the 1N6024UR/TR supports a junction and storage temperature range of –65 to +175 °C. Its DO-213AA glass package and metallurgical bonds ensure reliable operation in extended industrial, automotive under-hood, and aerospace environments where thermal cycling and sustained high temperatures occur.
What is the thermal resistance of the 1N6024UR/TR when mounted on FR4?
When mounted on an FR4 PCB with 1 oz copper and the recommended footprint, the 1N6024UR/TR exhibits a thermal resistance of 300 °C/W junction-to-ambient (RθJA) and 150 °C/W junction-to-end-cap (RθJL). These values define the derating curve shown in Figure 1 of the datasheet.
