Product details
Overview
SMBG5386AE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 180 V, ±10% tolerance (A suffix), rated test current of 5.0 mA, maximum dynamic impedance of 430 Ω at IZT, and peak surge current capability of 1750 A (8.3 ms half-sine). It regulates voltage in power supply overvoltage protection circuits.
For engineers reviewing the SMBG5386AE3/TR13 datasheet, SMBG5386AE3/TR13 pinout, SMBG5386AE3/TR13 application, or SMBG5386AE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current rating, thermal resistance (RθJL = 25 °C/W), DO-215AA gull-wing package compatibility, and RoHS-compliant matte-tin plating (e3).
Technical Context
This device operates as a precision voltage reference and transient clamp in DC power rails, leveraging its sharp reverse breakdown knee (IZK = 5.0 mA) and low dynamic impedance (430 Ω) to maintain stable regulation across varying load currents. Its 180 V Zener voltage targets high-voltage industrial SMPS feedback loops and telecom surge suppression stages.
The DO-215AA gull-wing package enables visible solder joints and supports 260 °C reflow per J-STD-020B Level 1 moisture sensitivity-no dry pack required. Thermal performance relies on junction-to-lead conduction (25 °C/W), not ambient dissipation (90 °C/W), making it suitable for PCBs with localized copper heatsinking near the cathode band.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 180 V ±10% - sets clamping threshold for 200 V-class DC bus overvoltage protection |
| Test Current (IZT) | 5.0 mA - operating point where VZ and dynamic impedance are specified |
| Max Dynamic Impedance (ZZT) | 430 Ω - limits voltage deviation under small-signal AC ripple superimposed on DC bias |
| Max Regulator Current (IZM) | 26.4 mA - maximum continuous DC current at 5 W dissipation with TL < 25 °C |
| Surge Current (IZSM) | 1750 A (8.3 ms half-sine) - withstands lightning-induced transients in telecom line cards |
| Junction-to-Lead Thermal Resistance | 25 °C/W - enables direct thermal coupling to PCB copper pour for reliable 5 W operation |
| Reverse Leakage (IR) | 0.5 µA @ 144 V - ensures minimal standby power loss in high-impedance sensing networks |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by a band on the body; terminals are anode (unbanded end) and cathode (banded end); polarity must be observed during PCB layout to ensure correct reverse-bias operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or low-side return path; serves as voltage reference point for Zener regulation |
| Cathode | Regulated output node | Banded terminal connected to protected rail; clamps voltage to 180 V when reverse current exceeds IZK |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5386B equivalent | Identical electrical specs and test methods to legacy through-hole 1N5386B-enables drop-in replacement in upgraded SMT designs |

| Gull-wing lead form (DO-215AA) | Enables visual solder joint inspection and reduces tombstoning risk vs. J-bend packages like DO-214AA |
| High surge current rating | 1750 A non-repetitive peak withstand capability supports IEC 61000-4-5 Level 4 surge immunity compliance |
| Stable voltage vs. temperature | Specified over -65 °C to +150 °C junction range-suitable for automotive engine bay and industrial outdoor enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5386B | Through-hole DO-41 package; identical VZ, IZT, ZZT, and IZSM; non-RoHS Sn/Pb plating | Requires axial-leaded footprint and wave soldering; unsuitable for high-density SMT assemblies | Select when legacy through-hole manufacturing is retained and JEDEC 1N5386B qualification is mandatory |
| SMBJ5386B | Same Zener specs but DO-214AA J-bend package; RθJA = 90 °C/W (vs. 25 °C/W for SMBG5386AE3/TR13) | Lower thermal performance limits continuous power to ~1.4 W on FR4; less effective for sustained overvoltage events | Select only for cost-sensitive, low-duty-cycle clamping where thermal margin is not critical |
Compared with 1N5386B and SMBJ5386B, SMBG5386AE3/TR13 uniquely combines SMT gull-wing manufacturability, RoHS compliance, and superior junction-to-lead thermal conduction-making it optimal for space-constrained, high-reliability 5 W Zener applications requiring visible solder joints and no dry pack.

FAQ
What is the Zener voltage tolerance of SMBG5386AE3/TR13?
The 'A' suffix in SMBG5386AE3/TR13 denotes ±10% Zener voltage tolerance, meaning its actual breakdown voltage falls between 162 V and 198 V at the specified test current of 5.0 mA. This tolerance is verified per JEDEC test methods and applies across the full operating temperature range of –65 °C to +150 °C.
Does SMBG5386AE3/TR13 require dry packing before reflow soldering?
No, SMBG5386AE3/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity level 1, confirmed by Microsemi's characterization. Its void-free epoxy encapsulation and RoHS-compliant matte-tin plating eliminate the need for dry pack or baking prior to standard 260 °C reflow profiles.
How does the DO-215AA package of SMBG5386AE3/TR13 improve thermal performance versus DO-214AA?
SMBG5386AE3/TR13 uses a gull-wing lead frame (DO-215AA) with direct junction-to-lead thermal resistance of 25 °C/W, significantly lower than the 90 °C/W junction-to-ambient rating of J-bend DO-214AA packages like SMBJ5386B. This enables full 5 W dissipation with proper PCB copper heatsinking at the leads.
Is SMBG5386AE3/TR13 electrically equivalent to 1N5386B?
Yes, SMBG5386AE3/TR13 is explicitly stated in the datasheet as electrically equivalent to JEDEC-registered 1N5386B, with identical Zener voltage, dynamic impedance, surge current, and leakage specifications. The only differences are package (DO-215AA vs. DO-41) and plating (RoHS matte-tin vs. Sn/Pb).
What is the maximum continuous Zener current for SMBG5386AE3/TR13 at 25 °C?
At lead temperature (TL) below 25 °C, SMBG5386AE3/TR13 supports a maximum continuous Zener current (IZM) of 26.4 mA, calculated as PD/VZM = 5.0 W / 189 V (180 V + 10%). This value assumes adequate thermal conduction from the leads to PCB copper.
