Product details
Overview
SMBG5386B/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 180 V, ±5% tolerance (B suffix), 5.0 mA test current (IZT), and dynamic impedance of 430 Ω at IZT - designed for precision voltage regulation in high-voltage power supply clamping and overvoltage protection circuits.
For engineers reviewing the SMBG5386B/TR13 datasheet, SMBG5386B/TR13 pinout, SMBG5386B/TR13 application, or SMBG5386B/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current capability (1750 A peak, 8.3 ms half-sine), thermal resistance (RθJL = 25 °C/W), and DO-215AA gull-wing package compatibility with automated SMT assembly.
Technical Context
This device operates in reverse-bias breakdown mode to maintain stable reference voltage across wide current (5.0 mA to 26.4 mA max IZM) and temperature (–65 °C to +150 °C) ranges. Its low leakage (<0.5 µA at VR = 144 V) and minimal voltage drift support reliable regulation under transient stress.
The DO-215AA gull-wing package enables visible solder joints and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity - eliminating dry-pack requirements. Thermal performance is specified for FR4 PCB mounting with recommended footprint (A = 8.13 mm, B = 2.16 mm, C = 2.79 mm).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 180 V ±5% at 5.0 mA - ensures tight regulation tolerance for high-voltage reference and clamp applications. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - supports sustained clamping in power supply front-end stages with adequate heatsinking. |
| Max Regulator Current (IZM) | 26.4 mA - defines maximum continuous DC current before thermal derating begins. |
| Surge Current (IZSM) | 1750 A (8.3 ms half-sine) - withstands high-energy transients like lightning-induced surges or inductive kickback. |
| Dynamic Impedance (ZZT) | 430 Ω at 5.0 mA - indicates moderate AC impedance affecting regulation stability under varying load currents. |
| Junction-to-Lead Thermal Resistance | 25 °C/W - enables efficient heat transfer to PCB copper, critical for reliability in compact high-power designs. |
| Reverse Leakage (IR) | <0.5 µA at 144 V - ensures minimal standby power loss and high impedance in off-state protection circuits. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; polarity requires banded end to be positive relative to anode during operation. Weight: 0.1 g. Moisture sensitivity level: IPC/JEDEC J-STD-020B Level 1 - no dry pack required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink terminal in forward bias; reference ground node in reverse-bias regulation | Connected to system ground or low-side return path; must remain at lower potential than cathode during Zener operation. |
| Cathode | Current source terminal in forward bias; regulated output node in reverse-bias breakdown | Connected to input rail or protected node; maintains stable 180 V reference when reverse-biased above breakdown threshold. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N53xxB Equivalent | Identical electrical characteristics and test methods to legacy through-hole 1N5386B - simplifies drop-in replacement in upgraded SMT designs. |
| Gull-wing Lead Geometry | Enables optical inspection of solder joints and improves mechanical reliability on FR4 boards versus J-bend packages. |
| RoHS Compliant Matte-Tin Plating | Meets lead-free assembly requirements without compromising solderability or intermetallic formation control. |
| Level 1 Moisture Sensitivity | Eliminates baking preconditioning prior to reflow - reduces manufacturing cycle time and cost. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5386B | Axial-leaded T-18 package; identical VZ, IZT, ZZT, and IZM; higher RθJA (125 °C/W vs. 90 °C/W) | Requires through-hole assembly and larger board area; unsuitable for high-density SMT layouts. | Select when legacy through-hole production or manual repair is required; not suitable for new SMT designs. |
| SMBJ5386 | J-bend DO-214AA package; same VZ and tolerance but higher ZZT (480 Ω); different pad layout and solder joint geometry | Less visible solder joints; slightly reduced surge robustness due to thermal path limitations of J-bend leads. | Choose only if DO-214AA footprint is already standardized; verify thermal margin with actual board layout. |
Compared with SMBG5386B/TR13, 1N5386B offers identical regulation specs but lacks SMT compatibility, while SMBJ5386 trades gull-wing inspectability and thermal performance for DO-214AA footprint reuse - making SMBG5386B/TR13 optimal for new high-reliability SMT designs demanding visible solder joints and superior thermal transfer.

FAQ
What is the Zener voltage tolerance for SMBG5386B/TR13?
The "B" suffix in SMBG5386B/TR13 denotes ±5% Zener voltage tolerance, meaning its measured VZ falls between 171 V and 189 V at 5.0 mA test current and 25 °C. This tolerance is verified per JEDEC test methods and applies across the full operating temperature range of –65 °C to +150 °C.
Does SMBG5386B/TR13 require dry packing before reflow soldering?
No, SMBG5386B/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity level 1, confirmed by Microsemi's qualification testing. It may be stored and processed directly without baking or dry-pack preconditioning - reducing manufacturing overhead and avoiding moisture-related defects.
What is the maximum continuous Zener current for SMBG5386B/TR13?
The maximum continuous Zener current (IZM) for SMBG5386B/TR13 is 26.4 mA at TL < 25 °C, calculated per Microsemi's Note 3 using P = 5.0 W and VZM = 189 V (upper limit of ±5%). Derating applies above 25 °C ambient or lead temperature per the power derating curve in Figure 1.
How does the DO-215AA package of SMBG5386B/TR13 differ from DO-214AA?
SMBG5386B/TR13 uses DO-215AA gull-wing leads, which provide coplanar terminations for optical solder-joint inspection and lower thermal resistance (RθJL = 25 °C/W) versus DO-214AA's J-bend configuration. The gull-wing geometry also improves mechanical retention on FR4 PCBs under thermal cycling stress.
Is SMBG5386B/TR13 RoHS compliant?
Yes, SMBG5386B/TR13 is RoHS compliant, featuring annealed matte-tin plating per Microsemi's specification. The "TR13" suffix confirms tape-and-reel packaging, and the device meets EU Directive 2011/65/EU requirements with no exemptions needed for lead, cadmium, or hexavalent chromium.
