Product details
Overview
1N6024UR-1/TR from Microsemi is a surface-mount 100 V, 5.0 mA test-current Zener diode in DO-213AA (SOD80/MLL34) MELF glass package, rated for 500 mW power dissipation at 25°C, with ±5% voltage tolerance and +0.110 %/°C temperature coefficient-used for precision voltage regulation in industrial power supplies and reference circuits.
For engineers reviewing the 1N6024UR-1/TR datasheet, 1N6024UR-1/TR pinout, 1N6024UR-1/TR application, or 1N6024UR-1/TR equivalent, key selection criteria include Zener voltage accuracy at IZT = 1.0 mA, dynamic impedance of 2600 Ω at IZT, reverse leakage ≤0.1 µA at 76 V, and thermal resistance of 300 °C/W junction-to-ambient on FR4.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with regulation defined at IZT = 1.0 mA and VZ = 100 V ±5%. Its DO-213AA hermetically sealed glass construction provides inherent radiation hardness and ESD insensitivity per MIL-STD-750 Method 1020.
Thermal performance is specified for mounting on 1 oz Cu FR4 with recommended footprint: RθJA = 300 °C/W and RθJL = 150 °C/W. The cathode band denotes polarity, requiring the banded end to be held positive relative to the anode during regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 100 V ±5% at IZT = 1.0 mA - defines stable regulation point under nominal bias |
| Power Dissipation PD | 0.5 W at TA ≤ 25°C - sets maximum continuous power on standard FR4 layout |
| Zener Impedance ZZT | 2600 Ω at IZT = 1.0 mA - determines AC ripple rejection and regulation stiffness |
| Reverse Leakage IR | ≤0.1 µA at VR = 76 V - ensures low standby current in high-impedance bias networks |
| Temp. Coefficient αVZ | +0.110 %/°C - quantifies voltage drift over temperature in precision references |
| Junction Temp. Range | –65°C to +175°C - supports operation in extended industrial and aerospace environments |
| Forward Voltage VF | 1.1 V at IF = 200 mA - relevant for polarity verification and ESD protection path design |
Pinout & Package
DO-213AA (SOD80/MLL34) MELF glass package: hermetically sealed cylindrical body with tin-lead or RoHS-compliant matte-tin end-cap plating; cathode identified by single black band; weight 0.04 g; tape-and-reel packaging per EIA-481-B (12 mm tape).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Reference ground node | Connected to circuit common; forms low-impedance return path during regulation |
| Cathode (banded end) | Regulated output node | Held at precise 100 V relative to anode; supplies stable bias to downstream circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass MELF construction | Enables radiation-hardened operation per MicroNote 050 and eliminates moisture-induced parameter shift |
| Internal metallurgical bonds | Ensures long-term reliability and thermal cycle robustness in high-vibration environments |
| Non-sensitive to ESD | Withstands human-body-model discharges without parameter degradation (MIL-STD-750 Method 1020) |
| Minimal capacitance | Typical <1 pF - preserves high-frequency stability in RF bias and fast-switching regulator feedback paths |
| RoHS-compliant option | e3 suffix available for commercial grade - meets EU Directive 2011/65/EU without lead content |
Applications
| Industrial Power Supply Reference | High-Voltage Sensor Biasing |
|---|---|
Use Scenario: Stabilizing feedback voltage in 100–200 V DC-DC converter secondary-side regulation loops. IC Role / Device Role / Timing Role: Two-terminal shunt reference providing fixed 100 V reference against which error amplifier compares output.

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 | Same electrical specs but in bulk (non-tape-and-reel) packaging; no TR suffix | Not suitable for automated SMT placement; requires manual or vibratory feed handling | Select 1N6024UR-1/TR when using pick-and-place equipment with 12 mm tape; choose 1N6024UR-1 for prototyping or low-volume hand assembly. |
| BZX85C100 | 100 V, ±5%, 1.3 W in DO-41 package; higher power but axial leaded and larger footprint | Requires through-hole PCB layout; unsuitable for high-density SMT designs | Choose BZX85C100 only if board space permits axial leads and >1.3 W dissipation is required; 1N6024UR-1/TR remains optimal for compact SMT 0.5 W regulation. |
Compared with 1N6024UR-1/TR, the bulk-packaged 1N6024UR-1 lacks tape-and-reel compatibility for automated assembly, while BZX85C100 trades SMT suitability for higher power and through-hole mounting-neither offers drop-in replacement capability due to package and footprint mismatch.

FAQ
What is the Zener voltage tolerance and test current for 1N6024UR-1/TR?
The 1N6024UR-1/TR has a nominal Zener voltage of 100 V with ±5% tolerance, measured at a test current IZT of 1.0 mA. This tolerance band defines the guaranteed regulation range (95 V to 105 V) under specified thermal conditions and is confirmed per Microsemi's T4-LDS-0228-1 datasheet revision 1.
Is 1N6024UR-1/TR RoHS compliant?
Yes, 1N6024UR-1/TR is RoHS compliant when ordered with the e3 suffix (though not present in this part number, RoHS versions are available as 1N6024UR-1/TR e3). The commercial-grade variant uses matte-tin end-cap plating and complies with EU Directive 2011/65/EU; non-RoHS versions use tin-lead plating.
What is the maximum reverse leakage current for 1N6024UR-1/TR?
The maximum reverse leakage current for 1N6024UR-1/TR is 0.1 µA at VR = 76 V, as specified in the Electrical Characteristics table on page 3 of the Microsemi datasheet. This low leakage supports high-impedance bias networks and precision reference applications where current draw must be minimized.
Can 1N6024UR-1/TR be used in high-temperature environments?
Yes, 1N6024UR-1/TR is rated for junction and storage temperatures from –65°C to +175°C. Its DO-213AA glass package and internal metallurgical bonds ensure reliable operation in extended industrial, automotive under-hood, and aerospace environments where thermal cycling and sustained high ambient temperatures occur.
What does the "TR" suffix indicate in 1N6024UR-1/TR?
The "TR" suffix in 1N6024UR-1/TR indicates tape-and-reel packaging per EIA-481-B standard using 12 mm carrier tape-enabling automated surface-mount assembly. This distinguishes it from the bulk-packaged 1N6024UR-1 and confirms compatibility with high-speed pick-and-place equipment used in volume production of the 1N6024UR-1/TR.
