Product details
Overview
SMBG5347C/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 10 V, ±2% tolerance (C suffix), 125 mA maximum regulator current (IZM), and DO-215AA gull-wing package. It regulates voltage across wide current and temperature ranges and is used in power supply overvoltage protection and reference circuits.
For engineers reviewing the SMBG5347C/TR13 datasheet, SMBG5347C/TR13 pinout, SMBG5347C/TR13 application, or SMBG5347C/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current capability (8.6 A), thermal resistance (25 °C/W junction-to-lead), and RoHS-compliant matte-tin plating.
Technical Context
This device operates in reverse-biased breakdown mode to maintain stable voltage under varying load and temperature conditions. Its dynamic impedance is 2.0 Ω at 150 mA test current (IZT), and it exhibits low leakage (<5 µA) at 7.2 V reverse voltage (VR).
The SMBG5347C/TR13 is rated for 5 W power dissipation at lead temperature ≤25 °C, with thermal resistance junction-to-lead of 25 °C/W and junction-to-ambient of 90 °C/W on FR4 board. It withstands non-repetitive 8.3 ms half-sine surge currents up to 8.6 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10 V ±2% at 125 mA - ensures precise voltage reference in feedback loops |
| Max Regulator Current (IZM) | 125 mA - defines maximum continuous DC current before thermal derating |
| Dynamic Impedance (ZZT) | 2.0 Ω at IZT = 150 mA - low impedance maintains regulation stability under load transients |
| Reverse Leakage (IR) | ≤5 µA at VR = 7.2 V - minimal standby power loss in high-impedance bias networks |
| Surge Current (IZSM) | 8.6 A (8.3 ms half-sine) - handles transient overvoltage events without failure |
| Thermal Resistance (RθJL) | 25 °C/W - enables efficient heat transfer to PCB copper for sustained 5 W operation |
| Package | DO-215AA gull-wing - provides visible solder joints and Level 1 moisture sensitivity (no dry pack required) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5347C | Axial-leaded T-18 package; identical electrical specs but different mechanical form factor and thermal path | Requires through-hole mounting and manual assembly; less suitable for high-density SMT production | Select when legacy through-hole design or hand-soldering is required; not drop-in compatible |
| SMBJ5347C | DO-214AA J-bend package; same Zener voltage/tolerance but higher RθJA (100 °C/W vs. 90 °C/W) and lower IZSM (7.5 A) | Lower surge robustness and reduced thermal performance on identical PCB layout | Acceptable for lower-stress environments where 8.6 A surge margin is not critical |
Compared with SMBG5347C/TR13, 1N5347C requires PCB redesign for through-hole placement and lacks gull-wing visual inspection, while SMBJ5347C offers similar SMT compatibility but trades 1.1 A surge headroom and 10 °C/W higher ambient thermal resistance.

FAQ
What is the Zener voltage tolerance of SMBG5347C/TR13?
The SMBG5347C/TR13 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its measured VZ at 125 mA falls within 9.8 V to 10.2 V at 25 °C. The tighter tolerance supports precision regulation tasks where 1% or 5% variants would introduce unacceptable error margins in feedback networks or reference circuits.
Does SMBG5347C/TR13 require dry packing for moisture sensitivity?
No, SMBG5347C/TR13 does not require dry packing. It carries IPC/JEDEC J-STD-020B Moisture Sensitivity Level 1 rating, meaning it can be stored indefinitely at ≤30 °C/85% RH without baking prior to reflow. This eliminates moisture-related popcorning risk and simplifies inventory handling and SMT line logistics for SMBG5347C/TR13.
What is the maximum surge current rating for SMBG5347C/TR13?
The SMBG5347C/TR13 is rated for a non-repetitive peak surge current (IZSM) of 8.6 A, defined as a single 8.3 ms half-sine waveform. This value is confirmed in the Electrical Characteristics table on page 3 of the Microsemi datasheet T4-LDS-0246-1. It reflects the device's ability to absorb transient energy without parametric shift or catastrophic failure when used in overvoltage clamp configurations.
How does the thermal resistance of SMBG5347C/TR13 compare between junction-to-lead and junction-to-ambient?
SMBG5347C/TR13 has RθJL = 25 °C/W and RθJA = 90 °C/W when mounted on an FR4 board with recommended footprint. The 65 °C/W difference highlights the importance of thermal coupling to the PCB copper pour: effective heatsinking via wide traces or internal planes significantly improves power handling beyond the 1.38 W ambient-limited rating, enabling full 5 W operation when lead temperature is maintained ≤25 °C.
Is SMBG5347C/TR13 RoHS compliant?
Yes, SMBG5347C/TR13 is RoHS compliant, indicated by the "e3" marking variant and matte-tin plating per MIL-STD-750 Method 2026. The "C" suffix confirms ±2% voltage tolerance, and the "TR13" denotes EIA-481-1-A tape-and-reel packaging with 12 mm carrier tape. All RoHS-compliant units meet EU Directive 2011/65/EU and are lead-free reflow compatible.
