Product details
Overview
1N6010UR/TR from Microsemi is a surface-mount 27 V Zener diode in DO-213AA (SOD80/MLL34) MELF package, rated for 500 mW power dissipation at 25°C, with ±5% voltage tolerance (B suffix), 70 mA test current (IZT), and 88 Ω dynamic impedance (ZZT) - used for precision voltage regulation in power supply feedback loops and reference circuits.
For engineers reviewing the 1N6010UR/TR datasheet, 1N6010UR/TR pinout, 1N6010UR/TR application, or 1N6010UR/TR equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (300°C/W junction-to-ambient), low leakage (<0.1 µA at 21 V), radiation-hardened construction, and RoHS-compliant matte-tin plating for commercial-grade reflow compatibility.
Technical Context
This device operates as a two-terminal voltage regulator in reverse-biased breakdown mode, with Zener voltage specified at 27 V ±5% under 70 mA DC test current (IZT). Its DO-213AA glass MELF package provides hermetic sealing and inherent radiation hardness per MicroNote 050.
It exhibits a positive temperature coefficient of +0.091%/°C, low typical capacitance (19 pF), and minimal ESD sensitivity (MIL-STD-750, Method 1020). Thermal derating begins above 25°C ambient, with full power limited to end-cap temperatures below 100°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 27 V ±5% at 70 mA - defines stable regulation point for feedback networks |
| Power Dissipation (PD) | 0.5 W at 25°C ambient - sets maximum continuous power in FR4 PCB layout with 1 oz Cu |
| Dynamic Impedance (ZZT) | 88 Ω at 70 mA - determines output voltage stability under load transients |
| Reverse Leakage (IR) | <0.1 µA at 21 V - ensures minimal quiescent current in high-impedance bias networks |
| Junction Temp Range | –65°C to +175°C - supports operation in extended industrial and aerospace environments |
| Thermal Resistance (RθJA) | 300°C/W - requires thermal pad design or airflow for >150 mW sustained operation |
| Temp Coefficient (αVZ) | +0.091%/°C - enables predictable drift compensation in temperature-critical references |
Pinout & Package
DO-213AA (SOD80/MLL34) glass MELF package: hermetically sealed cylindrical body with tin-lead or RoHS-compliant matte-tin plated end caps; cathode indicated by single band; polarity: banded end is cathode (positive during Zener operation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Reference ground node | Connected to circuit common; establishes 0 V reference for Zener voltage drop |
| Cathode (banded end) | Regulated output node | Provides stable 27 V relative to anode when reverse-biased above breakdown threshold |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass MELF construction | Enables operation up to +175°C junction temperature and intrinsic radiation hardness |

FAQ
What is the Zener voltage tolerance for 1N6010UR/TR?
The 1N6010UR/TR has a nominal Zener voltage of 27 V with ±5% tolerance, denoted by the "B" suffix in its part number per Microsemi's nomenclature. This tolerance is verified at 70 mA test current and 30°C lead temperature, and applies across the full operating temperature range of –65°C to +175°C junction temperature.
Is 1N6010UR/TR RoHS compliant?
Yes, the 1N6010UR/TR is RoHS compliant, indicated by the "e3" suffix in its full designation (1N6010BUR-1 e3). It features matte-tin plating on its DO-213AA end caps and meets EU RoHS Directive 2011/65/EU requirements - but only in commercial-grade versions, not screened military variants.
What package type does 1N6010UR/TR use?
The 1N6010UR/TR uses the DO-213AA package - also known as SOD80 or MLL34 - a hermetically sealed glass MELF (Metal Electrode Leadless Face) surface-mount package with cylindrical geometry and metallized end caps for soldering. Dimensions are 1.60–1.70 mm diameter and 3.30–3.70 mm length.
Does 1N6010UR/TR have radiation-hardened characteristics?
Yes, the 1N6010UR/TR is inherently radiation hard, as documented in Microsemi MicroNote 050. Its hermetic glass DO-213AA construction and silicon process provide tolerance to total ionizing dose (TID) and single-event effects (SEE), making it suitable for space and nuclear instrumentation applications without additional shielding.
What is the maximum Zener current (IZM) for 1N6010UR/TR?
The maximum dc Zener current (IZM) for 1N6010UR/TR is 70 mA at 27 V, derived from its 500 mW power rating and nominal voltage. At the upper tolerance limit (28.35 V), IZM reduces to approximately 66 mA to maintain safe power dissipation - consistent with the formula IZM = P / VZM cited in the datasheet.
