Product details
Overview
1N3036BUR-1 from Microsemi is a hermetically sealed, metallurgically bonded surface-mount Zener diode in DO-213AB (MELF/LL41) package, rated for 1 W DC power dissipation, with nominal Zener voltage of 47 V at 5.5 mA test current, dynamic impedance of 1500 Ω at IZT, and maximum reverse leakage current of 0.25 µA at 38 V. It serves as a precision voltage reference or regulation element in high-reliability power supply feedback paths.
For engineers reviewing the 1N3036BUR-1 datasheet, 1N3036BUR-1 pinout, 1N3036BUR-1 application, or 1N3036BUR-1 equivalent, key selection criteria include its ±5% voltage tolerance (B-grade), -55 °C to +175 °C junction temperature range, 50 °C/W thermal resistance (junction-to-end cap), RoHS-compliant option availability, and MIL-PRF-19500/115 qualification levels (JAN/JANTX/JANTXV).
Technical Context
This device operates as a two-terminal voltage regulator diode, conducting in reverse breakdown when cathode voltage exceeds anode by ≥47 V. Its glass-encapsulated MELF construction provides low parasitic capacitance and inherent radiation hardness per MicroNote 050, supporting stable operation under thermal cycling and ionizing environments.
The 1N3036BUR-1 exhibits a Zener voltage temperature coefficient of +0.102 %/°C and maintains regulation across 5.5 mA to 80 mA operating current (IZT to IZM), with forward voltage ≤1.2 V at 200 mA. Its metallurgically enhanced internal contact design reduces thermal resistance and improves long-term reliability versus standard axial-leaded equivalents.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4750A | 47 V ±5%, 1 W, DO-41 package, non-hermetic, commercial grade only | Lacks MIL qualification, higher leakage (5 µA), limited to 150 °C max junction temp | Select for cost-sensitive industrial designs where military screening and extreme temperature operation are unnecessary |
| SMF47A | 47 V ±5%, 1 W, SOD-123FL package, RoHS-compliant, 150 °C max junction temp | Plastic package, no hermetic seal or radiation hardness; smaller footprint but higher thermal resistance | Choose for space-constrained consumer or telecom boards needing lead-free compliance and automated assembly compatibility |
Compared with 1N3036BUR-1, the 1N4750A offers lower cost but sacrifices reliability assurance and temperature range, while the SMF47A trades hermeticity and radiation tolerance for compactness and RoHS alignment-making 1N3036BUR-1 the sole choice for mission-critical, high-temperature, or radiation-exposed deployments.

FAQ
What is the Zener voltage tolerance for 1N3036BUR-1?
The 1N3036BUR-1 has a nominal Zener voltage of 47 V with a ±5% tolerance (denoted by "B" in the part nomenclature), meaning its actual breakdown voltage falls between 44.65 V and 49.35 V at 5.5 mA test current and 25 °C. This tolerance is verified per MIL-PRF-19500/115 screening for JAN/JANTX/JANTXV versions and applies across the full qualified temperature range.
Is 1N3036BUR-1 suitable for high-temperature operation?
Yes, the 1N3036BUR-1 is rated for junction temperatures from -55 °C to +175 °C and features a thermal resistance of 50 °C/W (junction-to-end cap). Its hermetically sealed glass MELF package and metallurgically bonded construction enable reliable operation in downhole, avionics, and engine-control environments where sustained high-temperature exposure is required.
Does 1N3036BUR-1 have radiation hardness certification?
Yes, the 1N3036BUR-1 is inherently radiation hard as documented in Microsemi MicroNote 050. Its glass-encapsulated, metallurgically enhanced structure provides proven resistance to total ionizing dose (TID) and displacement damage, making it suitable for satellite power systems and nuclear instrumentation where radiation-induced parameter shift must be minimized.
What package type does 1N3036BUR-1 use?
The 1N3036BUR-1 uses the DO-213AB package - a hermetically sealed glass MELF (Metal Electrode Leadless Face) outline also known as LL41. It measures 2.39–2.67 mm in diameter and 4.80–5.21 mm in length, with a cathode band marking and tin/lead or RoHS-compliant matte-tin terminal finish.
Can 1N3036BUR-1 replace axial-leaded 1N3036B-1 in SMT assemblies?
Yes, the 1N3036BUR-1 is the surface-mount equivalent of the axial-leaded 1N3036B-1, sharing identical electrical specifications including 47 V Zener voltage, ±5% tolerance, and 1 W power rating. However, its DO-213AB package requires re-optimization of PCB pad layout and reflow profile versus the DO-41 footprint used by the through-hole version.
