Product details
Overview
1N6009UR/TR from Microsemi is a surface-mount 24 V, 5% tolerance Zener diode in DO-213AA (SOD80) MELF package, rated for 500 mW power dissipation at 25°C, with 62 Ω dynamic impedance at 5 mA test current and 0.1 µA reverse leakage at 18 V, used for precision voltage regulation in power supply feedback loops and reference circuits.
For engineers reviewing the 1N6009UR/TR datasheet, 1N6009UR/TR pinout, 1N6009UR/TR application, or 1N6009UR/TR equivalent, this page delivers verified electrical parameters, package dimensions, thermal derating behavior, Zener voltage temperature coefficient (+0.090 %/°C), and RoHS-compliant commercial-grade availability - all critical for stable low-power voltage reference design and BOM continuity planning.
Technical Context
This Zener diode operates in reverse breakdown with cathode-banded polarity, requiring the banded end to be held positive relative to the anode for regulation. Its metallurgically bonded glass construction ensures high reliability and inherent radiation hardness per MicroNote 050.
It exhibits minimal junction capacitance (typical <2 pF at 0 V), low forward voltage (1.1 V @ 200 mA), and stable regulation across –65°C to +175°C junction temperature range, with thermal resistance junction-to-ambient of 300°C/W on FR4 board using recommended footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 24 V ±5% at 5 mA test current - defines nominal regulation point with tight tolerance for feedback accuracy |
| Power Dissipation (PD) | 0.5 W at 25°C ambient - sets maximum continuous power handling before thermal derating applies |
| Dynamic Impedance (ZZT) | 62 Ω at IZT = 5 mA - determines output voltage variation under load current changes |
| Reverse Leakage (IR) | 0.1 µA at VR = 18 V - ensures minimal error current in high-impedance reference paths |
| Temp. Coefficient (αVZ) | +0.090 %/°C - quantifies voltage drift over temperature; enables compensation in precision designs |
| Junction Temp. Range | –65°C to +175°C - supports operation in extended industrial and aerospace environments |
| Forward Voltage (VF) | 1.1 V at 200 mA - relevant for reverse-polarity protection or clamp circuit integration |
Pinout & Package
DO-213AA (SOD80 / MLL34) hermetically sealed glass MELF package with tin-lead or RoHS-compliant matte-tin end-cap plating; cathode indicated by single band; polarity requires banded end to be positive during Zener operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Regulated output node | Connected to higher potential side; voltage referenced to anode; band identifies polarity for correct PCB orientation |
| Anode (unbanded end) | Reference/ground node | Typically tied to system ground or feedback divider low-side; completes Zener conduction path |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount DO-213AA package | Enables automated assembly and compact layout while maintaining glass-diode reliability and low parasitic capacitance |
| 5% Zener voltage tolerance (B suffix) | Provides tighter regulation than 10% variants, reducing need for post-calibration in mid-precision applications |
| Inherent radiation hardness | Validated per Microsemi MicroNote 050 - suitable for space-qualified and high-reliability systems without additional shielding |
| Non-ESD-sensitive construction | Passes MIL-STD-750 Method 1020 - eliminates need for ESD handling protocols during manufacturing and test |
| RoHS-compliant option (e3) | Matte-tin end-cap plating meets EU RoHS Directive 2011/65/EU for commercial-grade units only |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6009UR-1 | No tape-and-reel packaging; bulk or ammo-pack only; identical electrical specs and DO-213AA package | Lacks TR suffix - not optimized for high-speed pick-and-place; suitable for prototyping or low-volume hand assembly | Select 1N6009UR-1 when reel packaging is unnecessary and manual handling is acceptable. |
| BZX84-C24LT1G | SOT-23 package (3.0 × 1.4 × 1.3 mm); 24 V ±5%; 300 mW rating; 90 Ω ZZT; higher thermal resistance | Smaller footprint but lower power rating and higher dynamic impedance - less stable under varying load conditions | Choose BZX84-C24LT1G only if board space is constrained and power dissipation remains below 300 mW. |
Compared with 1N6009UR/TR, the 1N6009UR-1 offers identical regulation performance without tape-and-reel convenience, while BZX84-C24LT1G trades package size for reduced power capability and higher impedance - making 1N6009UR/TR optimal for thermally demanding, medium-precision 24 V reference applications.

FAQ
What is the Zener voltage tolerance of the 1N6009UR/TR?
The 1N6009UR/TR has a nominal Zener voltage of 24 V with a ±5% tolerance, indicated by the "B" suffix in its part nomenclature. This tolerance is measured at 5 mA test current and ensures regulation within 22.8 V to 25.2 V under standard conditions, supporting mid-precision feedback and reference applications without trimming.
Does the 1N6009UR/TR meet RoHS requirements?
Yes, the 1N6009UR/TR is RoHS compliant (e3 marking), featuring matte-tin end-cap plating per EU Directive 2011/65/EU. This compliance applies only to commercial-grade units; military-screened variants use tin-lead plating and are not RoHS compliant.
What is the maximum reverse leakage current for the 1N6009UR/TR?
The 1N6009UR/TR specifies a maximum reverse leakage current (IR) of 0.1 µA at VR = 18 V and 30°C. This ultra-low leakage supports high-impedance reference circuits and minimizes error contributions in precision analog signal chains.
How does thermal derating affect the 1N6009UR/TR's power handling?
The 1N6009UR/TR is rated for 0.5 W at 25°C ambient, with linear derating beginning at 300°C/W junction-to-ambient thermal resistance. Power must be reduced by 1.67 mW/°C above 25°C on FR4 board with recommended footprint, reaching zero dissipation at 175°C junction temperature.
Is the 1N6009UR/TR suitable for high-reliability screening per MIL-PRF-19500?
No - the 1N6009UR/TR is a commercial-grade part with "UR" designation and no prefix (e.g., MQ, MX). MIL-PRF-19500 screening requires prefixed versions like MQ1N6009BUR-1; the TR suffix indicates tape-and-reel packaging only, not enhanced reliability screening.
