Product details
Overview
SMBG5386C/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 180 V, ±2% tolerance (C suffix), 5.0 mA test current (IZT), 430 Ω dynamic impedance (ZZT), and maximum regulator current of 26.4 mA - used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5386C/TR13 datasheet, SMBG5386C/TR13 pinout, SMBG5386C/TR13 application, or SMBG5386C/TR13 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (RθJA = 90 °C/W), surge current rating (IZSM = 1750 A), moisture sensitivity level (MSL Level 1), and RoHS-compliant matte-tin plating.
Technical Context
This device operates as a reverse-biased silicon Zener diode with sharp breakdown knee at 180 V, specified at TL = 30 °C and measured 40 ±10 ms after DC current application. Its dynamic impedance of 430 Ω is measured at 1 kHz with 10% RMS AC modulation superimposed on IZT = 5.0 mA.
Thermal performance is defined for mounting on FR4 PCB (1 oz Cu) with recommended footprint: RθJL = 25 °C/W (junction-to-lead), RθJA = 90 °C/W (junction-to-ambient), enabling 5.0 W dissipation only when lead temperature remains below 25 °C - otherwise derated per Figure 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 180 V ±2% at IZT = 5.0 mA - ensures tight regulation in high-voltage reference and clamp circuits. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management via copper pour or heatsink to sustain full rating. |
| Dynamic Impedance (ZZT) | 430 Ω at 1 kHz, 10% AC modulation on IZT - determines output voltage stability under varying load current. |
| Max Regulator Current (IZM) | 26.4 mA - derived from P/VZM = 5.0 W / 183.6 V (high-end tolerance), sets max DC bias for regulation. |
| Surge Current (IZSM) | 1750 A (8.3 ms half-sine) - enables transient overvoltage clamping without failure in surge-prone systems. |
| Junction Temperature Range | –65 to +150 °C - supports operation in industrial and automotive under-hood environments. |
| Moisture Sensitivity | IPC/JEDEC J-STD-020B Level 1 - no dry pack or baking required before reflow soldering. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; polarity: banded end is cathode (must be biased negative relative to anode for Zener operation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener reference ground | Connected to system ground or low-side return path; carries forward current up to 1.0 A (VF = 1.2 V). |
| Cathode | Zener breakdown terminal / regulated output node | Banded end; connected to voltage rail being clamped or regulated; sustains 180 V reverse bias with minimal leakage (IR ≤ 0.5 µA at VR = 144 V). |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5386B equivalence | Identical electrical characteristics and testing to legacy through-hole 1N5386B - enables drop-in replacement in upgraded SMT designs. |
| Gull-wing lead form | Visible solder joints per DO-215AA outline - supports automated optical inspection (AOI) and rework accessibility. |
| RoHS-compliant matte-tin plating | e3 marking per nomenclature - meets lead-free assembly requirements without compromising solderability (MIL-STD-750, method 2026). |
| High surge withstand | 1750 A non-repetitive surge rating - protects downstream circuitry from lightning-induced transients or inductive kickback. |
| Stable voltage vs. current | Low dynamic impedance (430 Ω) and minimal VZ drift across IZT range - maintains regulation accuracy under load variation. |
Applications
| Switch-Mode Power Supply Feedback | Industrial Motor Drive Overvoltage Clamp |

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 specs; non-RoHS (Sn/Pb plating). | Requires through-hole assembly; unsuitable for high-density SMT layouts or automated AOI. | Select when legacy board repair or mixed-technology designs demand axial compatibility. |
| SMBJ5386C | DO-214AA J-bend package; same electrical specs but higher RθJA (100 °C/W vs. 90 °C/W); identical RoHS e3 marking. | Lower thermal efficiency on FR4; may require larger copper area to achieve same 5 W dissipation. | Select when existing DO-214AA footprint reuse is prioritized over optimal thermal performance. |
Compared with 1N5386B and SMBJ5386C, SMBG5386C/TR13 delivers superior thermal performance (RθJA = 90 °C/W), visible gull-wing solder joints for process control, and guaranteed RoHS compliance - making it optimal for new SMT designs requiring high reliability and manufacturability.

FAQ
What is the Zener voltage tolerance of SMBG5386C/TR13?
The "C" suffix in SMBG5386C/TR13 denotes ±2% Zener voltage tolerance at IZT = 5.0 mA and TL = 30 °C. This corresponds to a guaranteed VZ range of 176.4 V to 183.6 V, verified per Microsemi's T4-LDS-0246-1 test methodology using 40 ±10 ms DC current application.
Does SMBG5386C/TR13 require dry packing before reflow soldering?
No - SMBG5386C/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity level (MSL) Level 1, meaning it is not hygroscopic and does not require dry pack, baking, or special handling prior to reflow. This simplifies manufacturing logistics and reduces cost for high-volume SMT lines.
What is the maximum surge current rating for SMBG5386C/TR13?
SMBG5386C/TR13 is rated for 1750 A peak non-repetitive surge current (IZSM), defined as a single 8.3 ms half-sine waveform. This value is confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0246-1 datasheet and reflects its capability to absorb high-energy transients without parametric shift or failure.
How does the thermal resistance of SMBG5386C/TR13 compare to similar Zeners?
SMBG5386C/TR13 has RθJA = 90 °C/W when mounted on FR4 (1 oz Cu) with the recommended pad layout, which is 10 °C/W lower than the DO-214AA SMBJ5386C variant. This 10% improvement directly enables higher sustained power dissipation or relaxed board-level thermal design in space-constrained applications.
Is SMBG5386C/TR13 compatible with lead-free reflow profiles?
Yes - SMBG5386C/TR13 features RoHS-compliant annealed matte-tin plating (e3 marking), qualified for standard lead-free reflow profiles up to 260 °C for 10 seconds (per MIL-STD-750, method 2026). Its solderability and intermetallic formation are validated for Pb-free SAC305 and similar alloys.
