Product details
Overview
1N4692UR-1/TR from Microsemi is a 500 mW surface-mount Zener diode in DO-213AA (SOD80/MLL34) MELF package, rated for 6.8 V nominal Zener voltage at 50 µA test current, with ±5% tolerance, 10.0 V maximum regulation change (∆VZ), and 5.1 µA max reverse leakage at 10.0 V. It delivers stable voltage regulation in low-power biasing and reference circuits across industrial temperature ranges.
For engineers reviewing the 1N4692UR-1/TR datasheet, 1N4692UR-1/TR pinout, 1N4692UR-1/TR application, or 1N4692UR-1/TR equivalent, key selection factors include its low 50 µA Zener test current, hermetically sealed glass construction, MIL-PRF-19500 up-screening capability, RoHS-compliant commercial version, and minimal 1.5 V forward voltage at 100 mA.
Technical Context
The 1N4692UR-1/TR operates as a precision shunt voltage regulator with a sharp breakdown knee at low test current (50 µA), enabling accurate low-current biasing in sensor interfaces and analog front-ends. Its metallurgically bonded silicon die within a hermetically sealed glass MELF case ensures high reliability and radiation hardness per MicroNote 050.
Designed for stable operation from –65 °C to +175 °C junction temperature, it exhibits 100 °C/W junction-to-end-cap thermal resistance when mounted on FR4 with recommended footprint, supporting continuous 0.5 W dissipation below 125 °C end-cap temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 6.8 V at IZT = 50 µA - defines primary regulation point for low-current reference designs |
| Zener Tolerance | ±5% - standard accuracy for general-purpose voltage clamping and biasing |
| Max Regulation Change | 0.90 V (∆VZ) - quantifies voltage shift between 10 µA and 100 µA operating currents |
| Reverse Leakage | 5.1 µA at VR = 10.0 V - ensures minimal parasitic current in high-impedance sensing nodes |
| Power Dissipation | 0.5 W - supports continuous regulation in compact SMT layouts without forced cooling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4734A | Through-hole DO-41 package; 6.8 V ±5%; 50 mA IZM; higher 100 µA IZT | Requires PCB through-hole mounting; unsuitable for high-density SMT layouts | Select when legacy board compatibility or higher surge current margin is required |
| BZX55C6V8 | DO-35 package; 6.8 V ±5%; 5 mA IZM; 5 µA IZT; non-hermetic epoxy body | Limited power handling (500 mW not sustained); lower reliability in humid environments | Select for cost-sensitive consumer applications where hermeticity is not mandated |
Compared with 1N4692UR-1/TR, the 1N4734A offers higher surge current capability but lacks surface-mount compatibility, while the BZX55C6V8 reduces cost and size but sacrifices hermetic sealing and thermal robustness-making the 1N4692UR-1/TR optimal for high-reliability SMT designs demanding stable 6.8 V regulation at low current.

FAQ
What is the Zener voltage tolerance for 1N4692UR-1/TR?
The 1N4692UR-1/TR has a nominal Zener voltage of 6.8 V with a standard tolerance of ±5%, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0240-1 datasheet. Tighter 2% and 1% tolerances are available under different part number suffixes (C and D), but the base 1N4692UR-1/TR variant uses ±5%.
Does 1N4692UR-1/TR require special handling for ESD sensitivity?
No-1N4692UR-1/TR is non-sensitive to ESD per MIL-STD-750 Method 1020, as confirmed in the Applications/Benefits section of the datasheet. Its hermetic glass package and metallurgical construction inherently suppress electrostatic discharge damage, eliminating need for special ESD handling protocols during assembly.
What is the maximum steady-state power dissipation for 1N4692UR-1/TR?
The maximum steady-state power dissipation for 1N4692UR-1/TR is 0.5 W, valid when the end-cap temperature remains below 125 °C or ambient temperature stays under 50 °C on an FR4 board with 1 oz copper and the recommended footprint. Derating applies above those temperatures per Figure 1.
Is 1N4692UR-1/TR RoHS compliant?
Yes-RoHS-compliant versions of 1N4692UR-1/TR are available with matte-tin plating (designated by "e3" in the nomenclature), but only for commercial-grade devices. The standard non-RoHS variant uses tin-lead plating; both meet MIL-STD-750 solderability requirements.
What does the "TR" suffix indicate in 1N4692UR-1/TR?
"TR" denotes tape-and-reel packaging per EIA-481-1-B standard, enabling automated pick-and-place assembly. This suffix does not affect electrical or thermal specifications-it solely indicates packaging format and is optional for reel-based manufacturing workflows.
