Product details
Overview
SMBG5347A/TR13 from Microsemi is a surface-mount 5 W Zener diode with a nominal Zener voltage of 10 V ±10%, 125 mA maximum regulator current (IZM), 2.0 Ω dynamic impedance (ZZT), and DO-215AA gull-wing package. It regulates voltage across wide current and temperature ranges in power supply reference and overvoltage protection circuits.
For engineers reviewing the SMBG5347A/TR13 datasheet, SMBG5347A/TR13 pinout, SMBG5347A/TR13 application, or SMBG5347A/TR13 equivalent, this page delivers verified electrical parameters, thermal derating behavior, RoHS-compliant plating details, and direct alternatives for voltage reference design validation.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, maintaining stable output voltage under varying load and temperature conditions. Its 10 V nominal Zener voltage is specified at 125 mA test current (IZT) with 2.0 Ω dynamic impedance at that point.
The SMBG5347A/TR13 uses a void-free thermosetting epoxy case rated UL94V-0, features cathode band polarity marking, and achieves IPC/JEDEC J-STD-020B Level 1 moisture sensitivity-no dry pack required. Thermal resistance is 25 °C/W junction-to-lead and 90 °C/W junction-to-ambient on FR4 with recommended footprint.
Key Specifications

|---|---|
| Zener Voltage (VZ) | 10 V ±10% at 125 mA - defines stable regulation point for feedback networks |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - sets maximum continuous thermal load without heatsink |
| Dynamic Impedance (ZZT) | 2.0 Ω at IZT = 125 mA - determines output voltage stability under load transients |
| Maximum Regulator Current (IZM) | 475 mA - peak DC current before exceeding 5 W rating at high-end VZ (11 V) |
| Reverse Leakage (IR) | 5.0 µA at VR = 7.2 V - ensures minimal quiescent current in standby mode |
| Junction Temperature Range | –65 to +150 °C - supports operation in automotive under-hood and industrial control environments |
| Thermal Resistance (RθJL) | 25 °C/W - enables accurate junction temperature estimation from lead temperature measurement |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5347B | Axial-leaded T-18 package; identical VZ, IZT, ZZT, and IR specs per JEDEC. | Requires through-hole PCB assembly; not suitable for high-density SMT designs. | Select when legacy board repair or mixed-technology assembly is required. |
| SMBJ5347B | DO-214AA J-bend package; same electrical specs but different thermal resistance (RθJA = 80 °C/W vs. 90 °C/W). | Better airflow cooling in open-frame enclosures; slightly higher power handling at TA = 25 °C. | Select when board layout allows J-bend footprint and improved ambient thermal performance is needed. |
Compared with SMBG5347A/TR13, 1N5347B requires through-hole mounting and lacks gull-wing visual inspection capability, while SMBJ5347B offers lower junction-to-ambient resistance but differs in mechanical fit and reflow profile compatibility.

FAQ
What is the Zener voltage tolerance for SMBG5347A/TR13?
The SMBG5347A/TR13 has a Zener voltage tolerance of ±10%, meaning its regulated voltage falls between 9.0 V and 11.0 V at the specified test current of 125 mA. This tolerance is indicated by the "A" suffix in the part number per Microsemi's nomenclature. The device maintains this specification across its full operating temperature range of –65 to +150 °C.
Does SMBG5347A/TR13 require dry packing before reflow soldering?
No, SMBG5347A/TR13 does not require dry packing before reflow soldering. It carries an IPC/JEDEC J-STD-020B moisture sensitivity level of "Level 1", which means it can be stored indefinitely at ambient conditions (≤30 °C / 60% RH) without baking. This eliminates pre-reflow baking steps and reduces manufacturing risk of popcorning during reflow.
What is the maximum surge current rating for SMBG5347A/TR13?
The SMBG5347A/TR13 has a maximum non-repetitive Zener surge current (IZSM) of 8.6 A for an 8.3 ms half-sine waveform. This rating is validated per Microsemi's test methodology and reflects the device's ability to absorb transient energy without parametric shift or catastrophic failure-critical for overvoltage protection in automotive and industrial power rails.
How does the thermal resistance of SMBG5347A/TR13 affect its power handling?
The SMBG5347A/TR13 has a junction-to-ambient thermal resistance (RθJA) of 90 °C/W when mounted on FR4 with the recommended footprint. At 25 °C ambient, this limits continuous power dissipation to approximately 1.38 W unless lead temperature (TL) is actively controlled below 25 °C. For full 5 W operation, TL must remain ≤25 °C-achievable via copper pour, thermal vias, or heatsinking to leads.
Is SMBG5347A/TR13 RoHS compliant?
Yes, SMBG5347A/TR13 is RoHS compliant. The "e3" designation in Microsemi's internal marking scheme (visible as "5347A" on the device body) confirms annealed matte-tin plating meeting EU Directive 2011/65/EU and China RoHS II requirements. It is compatible with both Pb-free and SnPb soldering processes and passes MIL-STD-750 Method 2026 solderability testing.
