Product details
Overview
SMBG5383A/TR13 from Microsemi is a surface-mount 5 W Zener diode with a nominal breakdown voltage of 150 V, ±10% tolerance (A-suffix), rated for 8.0 mA test current (IZT), 330 Ω maximum dynamic impedance (ZZT), and 31.6 mA maximum regulator current (IZM) at TL < 25 °C. It operates in power supply overvoltage clamping and voltage reference circuits across industrial control and telecom power stages.
For engineers reviewing the SMBG5383A/TR13 datasheet, SMBG5383A/TR13 pinout, SMBG5383A/TR13 application, or SMBG5383A/TR13 equivalent, this page delivers verified electrical parameters, DO-215AA gull-wing package details, JEDEC 1N5383A-compliant performance, thermal derating behavior, and RoHS-compatible plating options - all confirmed from Microsemi's official T4-LDS-0246-1 Rev. 1 specification.
Technical Context
This device functions as a precision voltage reference and transient suppressor in DC bias networks, leveraging its stable 150 V Zener voltage at 8.0 mA IZT and low 330 Ω dynamic impedance to minimize voltage drift under load variation. Its 5 W power rating is valid only when lead temperature (TL) remains below 25 °C; derating begins at 25 °C per the published curve.
The SMBG5383A/TR13 uses a void-free UL94V-0 epoxy case with gull-wing matte-tin terminals, cathode polarity marked by a band, and IPC/JEDEC J-STD-020B Level 1 moisture sensitivity - eliminating dry-pack requirements. It withstands non-repetitive 8.3 ms half-sine surge currents up to 1500 A (IZSM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 150 V ±10% at 8.0 mA IZT - defines clamping threshold in overvoltage protection and sets reference level in feedback loops. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management via PCB copper area or heatsinking to sustain full rating. |
| Dynamic Impedance (ZZT) | 330 Ω max at 8.0 mA - determines output voltage stability under varying load current in regulation applications. |
| Max Regulator Current (IZM) | 31.6 mA - maximum continuous DC current before exceeding 5 W at worst-case VZ (165 V). |
| Surge Current (IZSM) | 1500 A (8.3 ms half-sine) - enables robust transient suppression without failure in surge-prone power rails. |
| Junction Temperature Range | –65 °C to +150 °C - supports operation in extended industrial and outdoor environments. |
| Thermal Resistance (RθJL) | 25 °C/W - quantifies heat transfer efficiency from junction to lead; critical for layout thermal design. |
Pinout & Package
Package: DO-215AA gull-wing surface-mount plastic case (UL94V-0), 0.1 g weight, cathode indicated by band. Compatible with EIA-481-1-A 12 mm tape-and-reel (TR13 suffix confirms this configuration).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to circuit ground or lower potential node during Zener operation (reverse-biased mode). |
| Cathode | High-side connection point | Banded terminal; connected to input rail or higher potential node - establishes 150 V reference/clamp voltage relative to anode. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5383A equivalence | Identical electrical characteristics and testing - enables drop-in replacement in legacy through-hole designs using adapter footprints or redesign. |
| Gull-wing lead form | Visible solder joints and automated optical inspection compatibility - improves manufacturing yield and rework accessibility on high-density PCBs. |
| Level 1 moisture sensitivity | No dry pack required - reduces handling cost and eliminates bake-out steps prior to reflow assembly. |
| RoHS-compliant matte-tin plating | Meets IPC-J-STD-006B solderability requirements - ensures reliable wetting and intermetallic formation during Pb-free reflow. |
| High surge current capability | 1500 A non-repetitive 8.3 ms half-sine - protects downstream components against lightning-induced or inductive-switching transients. |
Applications
| Industrial Power Supply Protection | Telecom DC-DC Reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5383A | Through-hole DO-41 package; identical VZ, IZT, ZZT, and IZM specs per JEDEC standard. | Requires axial-leaded footprint and wave soldering; not suitable for automated SMT lines. | Select when retrofitting legacy boards or where manual assembly is preferred and space permits larger package. |
| SMBJ5383A | Same Zener voltage and tolerance but in DO-214AA (J-bend) package; RθJA = 90 °C/W vs. SMBG5383A's 25 °C/W (junction-to-lead). | Lower thermal performance in high-power continuous operation due to higher junction-to-ambient resistance. | Select when board layout constraints favor J-bend geometry or existing DO-214AA footprints exist; verify thermal margin at 31.6 mA. |
Compared with SMBG5383A/TR13, the 1N5383A offers identical electrical behavior but demands through-hole assembly, while SMBJ5383A trades superior thermal conduction (via gull-wing leads) for less optimal ambient cooling - making SMBG5383A/TR13 optimal for high-reliability SMT power regulation where lead-temperature control is feasible.

FAQ
What is the Zener voltage tolerance of SMBG5383A/TR13?
The SMBG5383A/TR13 has a ±10% Zener voltage tolerance, as indicated by the "A" suffix in its part number. This means its breakdown voltage ranges from 135 V to 165 V at the specified 8.0 mA test current (IZT), per Microsemi's T4-LDS-0246-1 Rev. 1 specification. The SMBG5383A/TR13 is not rated for tighter tolerances like ±5% (B-suffix) or ±2% (C-suffix).
Can SMBG5383A/TR13 be used as a direct replacement for 1N5383A?
Yes - the SMBG5383A/TR13 is explicitly stated in Microsemi's datasheet as electrically equivalent to JEDEC-registered 1N5383A, with identical VZ, IZT, ZZT, IZM, and surge ratings. However, it is not a mechanical drop-in: SMBG5383A/TR13 uses DO-215AA gull-wing packaging versus 1N5383A's DO-41 axial leads, requiring PCB footprint adaptation.
What is the maximum continuous current SMBG5383A/TR13 can handle?
The SMBG5383A/TR13 supports a maximum continuous regulator current (IZM) of 31.6 mA when lead temperature (TL) is maintained below 25 °C. At higher TL, power must be derated per the published curve - e.g., at TL = 75 °C, usable power drops to ~2.8 W, reducing IZM to approximately 18.5 mA at 150 V.
Does SMBG5383A/TR13 require dry packing before reflow soldering?
No - the SMBG5383A/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it may be stored and processed without dry packing or baking. This simplifies handling and eliminates pre-reflow bake cycles, reducing manufacturing overhead and moisture-related defects.
What is the surge current rating of SMBG5383A/TR13?
The SMBG5383A/TR13 is rated for a non-repetitive peak surge current (IZSM) of 1500 A, defined as an 8.3 ms half-sine waveform. This rating is validated per Microsemi's test methodology and enables robust protection against lightning-induced transients and inductive switching spikes in DC power systems.
