Product details
Overview
1N5233DUR-1/TR from Microsemi is a surface-mount 6.0 V ±1% Zener diode in DO-213AA (SOD80) MELF package, rated for 500 mW steady-state power dissipation, with 7.0 Ω dynamic impedance at 20 mA test current and 5.0 µA max reverse leakage at 4.8 V. It serves as a precision voltage reference or shunt regulator in low-power analog circuits.
For engineers reviewing the 1N5233DUR-1/TR datasheet, 1N5233DUR-1/TR pinout, 1N5233DUR-1/TR application, or 1N5233DUR-1/TR equivalent, key selection criteria include its ±1% tolerance, hermetically sealed glass construction, MIL-PRF-19500 up-screening capability, RoHS-compliant matte-tin plating, and minimal capacitance for stable regulation across temperature.
Technical Context
This device operates as a silicon Zener diode in reverse breakdown mode, delivering stable 6.0 V regulation at IZT = 20 mA with a positive temperature coefficient of +0.038 %/°C. Its metallurgically bonded glass structure ensures mechanical robustness and hermetic sealing for reliability in harsh environments.
Designed for surface-mount assembly on FR4 PCBs with recommended footprint, it exhibits RθJA = 250 °C/W and RθJEC = 100 °C/W, requiring derating above 50 °C ambient or 125 °C end-cap temperature per Figure 2. Forward voltage is capped at 1.1 V @ 200 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 6.0 V ±1% at 20 mA - enables precise voltage clamping or reference generation in analog signal chains. |
| Power Dissipation PD | 0.5 W - supports continuous regulation in low-power sensor interfaces and bias networks without forced cooling. |
| Dynamic Impedance ZZT | 7.0 Ω @ 20 mA - ensures tight regulation under varying load currents, critical for stable feedback references. |
| Reverse Leakage IR | 5.0 µA @ 4.8 V - minimizes quiescent current loss in battery-powered circuits and high-impedance nodes. |
| Temp. Coefficient αVZ | +0.038 %/°C - provides predictable, low-drift behavior over -65 to +175 °C junction range. |
| Package | DO-213AA (SOD80) MELF - offers superior thermal performance vs. SOD-123 and compatibility with automated pick-and-place. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5233B-1TR | Same DO-213AA package and 6.0 V nominal rating, but ±5% tolerance (vs. ±1%) and non-RoHS plating. | Suitable for cost-sensitive industrial controls where tighter tolerance is not required. | Select when budget constraints outweigh precision needs and RoHS compliance is not mandated. |
| BZX55C6V2-TR | 6.2 V nominal, ±5% tolerance, DO-35 axial package; 10 Ω ZZT, 100 nA IR @ 4 V. | Used in through-hole legacy designs; lower leakage but higher impedance and voltage offset. | Choose only for board-level replacement in existing DO-35 layouts-no drop-in compatibility with 1N5233DUR-1/TR's MELF footprint. |
Compared with 1N5233B-1TR and BZX55C6V2-TR, the 1N5233DUR-1/TR delivers superior voltage accuracy and RoHS compliance in a surface-mount MELF package optimized for thermal performance and automated assembly-making it ideal for new designs demanding precision and manufacturability.

FAQ
What is the Zener voltage tolerance of the 1N5233DUR-1/TR?
The 1N5233DUR-1/TR has a Zener voltage tolerance of ±1%, specified at 20 mA test current and 25 °C. This tight tolerance is denoted by the "D" suffix in the part number and makes the 1N5233DUR-1/TR suitable for precision reference applications where calibration overhead must be minimized.
Is the 1N5233DUR-1/TR RoHS compliant?
Yes, the 1N5233DUR-1/TR is RoHS compliant, indicated by the "e3" suffix in its full nomenclature (1N5233DUR-1/TR e3). It features annealed matte-tin plating on end caps and meets commercial-grade RoHS requirements per Microsemi documentation T4-LDS-0232-1.
What is the maximum power dissipation for the 1N5233DUR-1/TR?
The 1N5233DUR-1/TR has a steady-state power dissipation rating of 0.5 W at end-cap temperature <125 °C or ambient temperature <50 °C on FR4 board. Derating is required above those temperatures per the curve in Figure 2 of the datasheet.
Does the 1N5233DUR-1/TR have a defined polarity marking?
Yes-the 1N5233DUR-1/TR uses a single cathode band to indicate polarity. The banded end is the cathode and must be connected to the higher-potential node during Zener operation; the unbanded end is the anode and connects to the lower-potential node (e.g., ground).
Can the 1N5233DUR-1/TR be used in high-reliability aerospace applications?
Yes-while the base 1N5233DUR-1/TR is commercial grade, Microsemi offers up-screened versions compliant with MIL-PRF-19500 (e.g., JAN, JANTX, JANTXV variants). These require different part number suffixes and are qualified for extended temperature, vibration, and life testing per military standards.
