Product details
Overview
SMBG5386CE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 180 V, ±2% tolerance (suffix C), RoHS-compliant matte-tin plating (e3), and gull-wing DO-215AA package. It regulates voltage across wide current and temperature ranges and withstands high surge stresses in power supply protection circuits.
For engineers reviewing the SMBG5386CE3/TR13 datasheet, SMBG5386CE3/TR13 pinout, SMBG5386CE3/TR13 application, or SMBG5386CE3/TR13 equivalent, key selection factors include its 180 V Zener voltage, 5.0 W power rating at TL < 25 °C, 430 Ω dynamic impedance at IZT = 5.0 mA, 26.4 mA maximum regulator current (IZM), and DO-215AA thermal resistance of 90 °C/W on FR4.
Technical Context
This device operates as a precision voltage reference and overvoltage clamp in DC power rails. Its breakdown behavior is characterized by low dynamic impedance (430 Ω at 5 mA) and minimal voltage drift versus current-critical for stable regulation under varying load conditions.
The SMBG5386CE3/TR13 features a gull-wing lead frame in DO-215AA, enabling visible solder joints and Level 1 moisture sensitivity (no dry pack required). It sustains non-repetitive 8.3 ms half-sine surge currents up to 1750 A and exhibits reverse leakage ≤0.5 µA at VR = 144 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 180 V ±2% at IZT = 5.0 mA - defines precise clamping threshold for overvoltage protection |
| Power Dissipation (PD) | 5.0 W at lead temperature < 25 °C - requires thermal management for sustained operation |
| Dynamic Impedance (ZZT) | 430 Ω at IZT = 5.0 mA - ensures stable regulation with minimal voltage shift under load variation |
| Maximum Regulator Current (IZM) | 26.4 mA - sets upper limit for continuous DC bias without exceeding power rating |
| Surge Current (IZSM) | 1750 A (8.3 ms half-sine) - enables robust transient suppression in industrial power systems |
| Reverse Leakage (IR) | ≤0.5 µA at VR = 144 V - guarantees low standby power loss in high-impedance bias networks |
| Thermal Resistance (RθJA) | 90 °C/W on FR4 (1 oz Cu) - informs PCB copper area requirements for thermal derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5386B | Same Zener voltage (180 V), ±5% tolerance, Sn/Pb plating, axial T-18 package | Requires through-hole assembly and manual rework; no RoHS compliance | Select only for legacy repair or non-RoHS production environments where footprint change is acceptable |
| SMBJ5386B | Same electrical specs, J-bend DO-214AA package, ±5% tolerance, RoHS-compliant | Different thermal profile (RθJA = 100 °C/W vs. 90 °C/W); less suitable for high-power density layouts | Choose when DO-214AA footprint compatibility is prioritized over optimal thermal performance |
Compared with SMBG5386CE3/TR13, 1N5386B lacks RoHS compliance and requires through-hole mounting, while SMBJ5386B trades thermal efficiency for package compatibility-making SMBG5386CE3/TR13 optimal for new RoHS-compliant, high-density SMT designs requiring precise 180 V regulation.

FAQ
What is the Zener voltage tolerance of SMBG5386CE3/TR13?
The SMBG5386CE3/TR13 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in the part number. This means its measured VZ falls within 176.4 V to 183.6 V at IZT = 5.0 mA and TL = 25 °C. This tight tolerance supports precision regulation in feedback loops and reference circuits where voltage accuracy is critical.
Does SMBG5386CE3/TR13 require dry packing before reflow soldering?
No, SMBG5386CE3/TR13 does not require dry packing. It carries IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it can be stored indefinitely at ambient conditions (≤30 °C/60% RH) without baking prior to reflow. This eliminates floor-life tracking and reduces manufacturing overhead in SMT lines.
What is the maximum continuous Zener current for SMBG5386CE3/TR13?
The maximum continuous Zener current (IZM) for SMBG5386CE3/TR13 is 26.4 mA at TL < 25 °C. This value is derived from PD = 5.0 W and VZM = 183.6 V (upper limit of ±2% tolerance), ensuring safe DC operation without exceeding thermal limits on properly designed PCBs.
How does SMBG5386CE3/TR13 compare to SMBJ5386B in thermal performance?
SMBG5386CE3/TR13 has a junction-to-ambient thermal resistance (RθJA) of 90 °C/W on FR4 with recommended footprint, while SMBJ5386B is rated at 100 °C/W. This 10 °C/W improvement allows SMBG5386CE3/TR13 to sustain higher power dissipation in compact layouts or elevated ambient temperatures without additional heatsinking.
Is SMBG5386CE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5386CE3/TR13 uses RoHS-compliant matte-tin plating (e3 suffix) and is qualified for lead-free reflow per JEDEC J-STD-020. Its solder temperature rating is 260 °C for 10 seconds, fully supporting standard Pb-free peak profiles (e.g., IPC Class 3) without degradation of solder joint integrity or Zener characteristics.
