Product details
Overview
1N4698UR-1E3/TR from Microsemi is a 500 mW surface-mount Zener diode in DO-213AA (SOD-80/MLL34) MELF package, rated for 11.0 V nominal Zener voltage at 50 µA test current, ±5% tolerance, with 0.11 V regulation change between 10 µA and 100 µA and 0.05 µA max reverse leakage at 8.4 V. It delivers stable voltage reference in precision analog power rails and low-power sensor biasing circuits.
For engineers reviewing the 1N4698UR-1E3/TR datasheet, 1N4698UR-1E3/TR pinout, 1N4698UR-1E3/TR application, or 1N4698UR-1E3/TR equivalent, key selection factors include its hermetically sealed glass construction, metallurgically bonded die for high reliability, minimal capacitance (<1.5 pF typical), radiation-hardened design per MicroNote 050, and RoHS-compliant matte-tin plating.
Technical Context
This device operates as a two-terminal voltage regulator in reverse-bias breakdown mode, with Zener voltage defined at IZT = 50 µA and specified regulation delta (∆VZ = 0.11 V) measured between 10 µA and 100 µA. Its thermal resistance junction-to-end cap is 100 °C/W on FR4 board, enabling stable operation up to +175 °C junction temperature.
The DO-213AA package features end-cap terminations with cathode band marking, tin-lead or RoHS matte-tin plating, and solderability compliant with MIL-STD-750 Method 2026. It is non-ESD-sensitive per MIL-STD-750 Method 1020 and inherently radiation-hardened.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C11 (ON Semiconductor) | DO-35 through-hole package; 500 mW; ±5% tolerance; 10 µA test current | Requires PCB through-hole mounting; higher thermal resistance (350 °C/W) | Select when legacy through-hole assembly is required and board space permits larger footprint |

The 1N4698UR-1E3/TR has a nominal Zener voltage of 11.0 V with a standard tolerance of ±5%, as confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0240-1 Rev. 2. Tighter 2% and 1% tolerances are available under different part number suffixes (C and D), but the -1E3/TR variant is specified at ±5%.
Is 1N4698UR-1E3/TR RoHS compliant?
Yes, the "E3" suffix in 1N4698UR-1E3/TR explicitly denotes RoHS compliance with matte-tin plating, as defined in the Part Nomenclature section on page 2 of the datasheet. This applies only to the commercial-grade version, which matches the ordering part number provided.
What is the maximum reverse leakage current for 1N4698UR-1E3/TR?
The maximum reverse leakage current (IR) for 1N4698UR-1E3/TR is 0.05 µA at VR = 8.4 V, per the Electrical Characteristics table on page 3. This ultra-low leakage supports high-impedance bias networks and precision reference designs where leakage-induced errors must be minimized.
Does 1N4698UR-1E3/TR require special ESD handling?
No, the 1N4698UR-1E3/TR is non-sensitive to ESD per MIL-STD-750 Method 1020, as stated in the Applications/Benefits section on page 1. Standard handling procedures are sufficient-no special ESD controls are required during assembly or testing.
What is the thermal resistance junction-to-end cap for 1N4698UR-1E3/TR?
The thermal resistance junction-to-end cap (RθJL) for 1N4698UR-1E3/TR is 100 °C/W when mounted on an FR4 PCB with 1 oz copper and the recommended footprint, as specified in the Maximum Ratings table on page 1. This value enables accurate thermal derating up to 175 °C junction temperature.
