Product details
Overview
SMBG5361C/TR13 from Microsemi is a surface-mount 5 W Zener diode with a nominal Zener voltage of 47 V, ±2% tolerance (C suffix), 5.0 Ω dynamic impedance at 125 mA test current, and DO-215AA gull-wing package. It regulates voltage in power supply feedback loops, overvoltage protection circuits, and reference voltage generation under broad temperature and current ranges.
For engineers reviewing the SMBG5361C/TR13 datasheet, SMBG5361C/TR13 pinout, SMBG5361C/TR13 application, or SMBG5361C/TR13 equivalent, this page delivers verified electrical parameters, JEDEC-compliant packaging details, thermal derating behavior, and RoHS-compliant alternatives for precision voltage regulation design.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown with minimal voltage variation across its rated current range (IZT = 125 mA, IZM = 100 mA). Its Zener voltage is specified at TL = 30 °C with 40 ms settling time after DC current application, per MicroNote 202.
The SMBG5361C/TR13 exhibits 25 °C/W junction-to-lead thermal resistance and 90 °C/W junction-to-ambient resistance on FR4 board with recommended footprint. It withstands non-repetitive 8.3 ms half-sine surge currents up to 210 A and maintains moisture sensitivity level 1 per J-STD-020B without dry pack.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5361B | Same 47 V ±2%, 5 W rating, but axial T-18 package with higher RθJA (150 °C/W) | Requires through-hole mounting and larger board area; unsuitable for high-density SMT layouts | Select when legacy repair, manual prototyping, or heat sinking via leads is preferred |
| SMBJ5361C | Identical electrical specs but DO-214AA J-bend package; 30% higher RθJA (117 °C/W) on same FR4 board | Lower thermal performance limits continuous current in compact enclosures without forced air | Select when existing J-bend footprint reuse is prioritized over thermal margin |
Compared with SMBG5361C/TR13, the 1N5361B offers identical regulation but requires board redesign for through-hole assembly, while SMBJ5361C retains SMT compatibility at the cost of reduced thermal efficiency-making SMBG5361C/TR13 optimal for space-constrained, thermally demanding applications.

FAQ
What is the Zener voltage tolerance for SMBG5361C/TR13?
The "C" suffix in SMBG5361C/TR13 denotes ±2% Zener voltage tolerance at 125 mA test current. This is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0246-1 Rev. 1, where SMBG5361B (±5%) and SMBG5361C (±2%) are explicitly differentiated. The tighter tolerance supports precision feedback in regulated power supplies where output accuracy is critical.
Does SMBG5361C/TR13 require dry packing before reflow soldering?
No, SMBG5361C/TR13 has moisture sensitivity level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ambient conditions without dry pack or baking. This is stated in the "APPLICATIONS / BENEFITS" section on page 1 and confirmed in the "MECHANICAL and PACKAGING" section on page 2 of the official datasheet.
What is the maximum surge current rating for SMBG5361C/TR13?
SMBG5361C/TR13 is rated for 210 A peak non-repetitive surge current (IZSM) using an 8.3 ms half-sine waveform, as listed in the Electrical Characteristics table on page 3. This value is derived from the device's 5 W power rating and thermal mass, enabling robust protection against common power-line transients.
Is SMBG5361C/TR13 RoHS compliant?
Yes, SMBG5361C/TR13 is RoHS compliant, indicated by the "e3" marking per the Part Nomenclature section on page 2. The device uses annealed matte-tin plating per MIL-STD-750 method 2026 and meets exemption 7a for lead in high-melting-temperature type solders.
What package type does SMBG5361C/TR13 use?
SMBG5361C/TR13 uses the DO-215AA gull-wing surface-mount package, defined in the "MECHANICAL and PACKAGING" section on page 2. Its dimensions (A = 1.96–2.10 mm, B = 4.06–4.57 mm) and pad layout (A = 8.13 mm, B = 2.16 mm) are fully documented on page 5 of the datasheet.
