Product details
Overview
1N6004UR-1/TR from Microsemi is a surface-mount 15 V Zener diode in DO-213AA (MLL34) glass MELF package, rated for 500 mW power dissipation at 25°C, with ±5% voltage tolerance (B suffix), 5 mA test current, and 33 Ω dynamic impedance at IZT. It serves as a precision voltage reference or shunt regulator in low-power analog circuits, power supply feedback loops, and overvoltage protection stages.
For engineers reviewing the 1N6004UR-1/TR datasheet, 1N6004UR-1/TR pinout, 1N6004UR-1/TR application, or 1N6004UR-1/TR equivalent, key selection criteria include its 15 V nominal Zener voltage, 5 mA regulation current, 33 Ω Zener impedance at test conditions, -65°C to +175°C operating temperature range, and RoHS-compliant matte-tin plating on commercial-grade end caps.
Technical Context
This device operates in reverse breakdown mode with cathode-banded polarity, requiring the banded end to be held positive relative to the anode for regulation. Its metallurgically bonded glass construction ensures stable Zener voltage under thermal cycling and supports high-reliability screening per MIL-PRF-19500 when ordered with appropriate prefixes.
The 1N6004UR-1/TR exhibits a +0.079 %/°C temperature coefficient and typical capacitance below 33 pF, making it suitable for noise-sensitive voltage reference applications where low parasitic capacitance and predictable thermal drift are critical design constraints.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C15 | 15 V, ±5%, SOT-23 package, 300 mW rating, 30 Ω ZZT, -55°C to +150°C range | Lower power rating and plastic package limit use in high-reliability or high-temp environments | Select when board space is constrained and full 500 mW dissipation is not required |
| 1N4744A | 15 V, ±5%, DO-41 axial package, 1 W rating, 16 Ω ZZT, -65°C to +200°C range | Through-hole mounting and higher power require different PCB layout and thermal design | Select when higher surge capability or legacy through-hole compatibility is needed |

FAQ
What is the Zener voltage tolerance of the 1N6004UR-1/TR?
The 1N6004UR-1/TR has a ±5% Zener voltage tolerance, denoted by the "B" suffix in its part number. This means its nominal 15 V Zener voltage is guaranteed between 14.25 V and 15.75 V when measured at 5 mA test current and 30°C lead temperature, supporting precise regulation without post-manufacturing calibration.
Is the 1N6004UR-1/TR RoHS compliant?
Yes, the 1N6004UR-1/TR is RoHS compliant, indicated by the "e3" suffix in its full nomenclature. It features matte-tin plating on commercial-grade end caps and meets EU Directive 2011/65/EU requirements, enabling use in lead-free reflow soldering processes without exemption requests.
What package type does the 1N6004UR-1/TR use?
The 1N6004UR-1/TR uses the DO-213AA (also known as MLL34 or SOD80) glass MELF package - a hermetically sealed cylindrical surface-mount format with metallurgically bonded end caps, optimized for thermal stability and high-reliability applications across military and industrial environments.
What is the maximum Zener current (IZM) for the 1N6004UR-1/TR?
The maximum Zener current IZM for the 1N6004UR-1/TR is 32 mA at nominal 15 V, calculated from its 500 mW power rating and voltage tolerance. This value ensures safe continuous operation without exceeding thermal limits when mounted on FR4 PCB with recommended footprint per Microsemi's package drawing.
How does the temperature coefficient affect the 1N6004UR-1/TR in precision circuits?
The 1N6004UR-1/TR has a +0.079 %/°C temperature coefficient, meaning its Zener voltage increases by approximately 11.85 mV per °C rise above 25°C. In precision reference designs, this drift must be factored into total error budgets - for example, a 50°C ambient shift introduces ~593 mV offset, necessitating compensation or system-level calibration.
