Product details
Overview
SMBG5340A/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 10 V, ±10% tolerance, 200 mA test current (IZT), and 790 Ω dynamic impedance (ZZT) at IZT - designed for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5340A/TR13 datasheet, SMBG5340A/TR13 pinout, SMBG5340A/TR13 application, or SMBG5340A/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current capability (10.7 A IZSM), thermal resistance (25 °C/W junction-to-lead), DO-215AA gull-wing package compatibility, and RoHS-compliant matte-tin plating.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, maintaining stable output voltage across wide operating current (1.0 mA to 790 mA) and temperature ranges (–65 °C to +150 °C). Its low dynamic impedance ensures minimal voltage variation under load transients.
The SMBG5340A/TR13 uses a void-free thermosetting epoxy case (UL94V-0), gull-wing leads with annealed matte-tin plating, and features moisture sensitivity level 1 - eliminating dry-pack requirements per IPC/JEDEC J-STD-020B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10 V ±10% - regulates at 9.0–11.0 V under 200 mA test current, enabling stable reference in 12 V rail clamping. |
| Power Dissipation (PD) | 5.0 W @ TL < 25 °C - supports high-energy transient suppression when mounted with adequate heat sinking. |
| Dynamic Impedance (ZZT) | 790 Ω @ IZT = 200 mA - limits output voltage shift to <0.16 V per 200 mA load change near regulation point. |
| Max Surge Current (IZSM) | 10.7 A (8.3 ms half-sine) - withstands IEC 61000-4-5 Level 4 surges without degradation. |
| Thermal Resistance (RθJL) | 25 °C/W - enables 200 °C/W junction-to-ambient rise on FR4 with recommended pad layout (A=8.13 mm, B=2.16 mm). |
| Reverse Leakage (IR) | 5.0 µA @ VR = 8.0 V - ensures low quiescent current in standby-mode protection circuits. |
| Junction Temperature Range | –65 °C to +150 °C - qualified for automotive under-hood and industrial control environments. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; banded end must be held positive relative to anode during operation. Leads are RoHS-compliant matte-tin plated and solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Current sink terminal in reverse bias | Connected to system ground or lower-potential node; carries full Zener current during regulation. |
| Cathode (banded end) | Regulated voltage output node | Provides stable 10 V reference; polarity must be observed to avoid forward conduction damage. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5340B equivalent | Identical electrical specs and test methods - enables drop-in replacement in legacy designs using axial 1N5340B. |
| Gull-wing lead form | Enables visual solder joint inspection and reduces tombstoning risk on fine-pitch PCBs. |
| Moisture Sensitivity Level 1 | No dry-pack or baking required before reflow - simplifies SMT line logistics and reduces handling cost. |
| High surge current rating | 10.7 A non-repetitive peak withstand - meets EN 61000-4-5 surge immunity for industrial power inputs. |
| Low forward voltage | 1.2 V @ 1.0 A - minimizes conduction loss if used in series-clamp configurations during fault conditions. |
Applications
| DC Power Supply Regulation | Overvoltage Protection Circuit |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5340B | Axial-leaded T-18 package; identical VZ, IZT, ZZT, and IZSM specs per JEDEC standard. | Requires through-hole assembly; unsuitable for high-density SMT layouts. | Select when legacy board repair or manual prototyping demands axial form factor. |
| SMBJ5340A | Same DO-214AA (J-bend) package; identical electrical specs but different mechanical footprint and thermal resistance (RθJA = 100 °C/W vs. 90 °C/W). | Lower profile than SMBG but less robust solder joint visibility; requires revised stencil design. | Select when existing DO-214AA footprint is fixed and RθJL > 25 °C/W is acceptable. |
Compared with SMBG5340A/TR13, 1N5340B offers identical regulation performance but mandates through-hole assembly, while SMBJ5340A shares electrical behavior but trades gull-wing inspectability for tighter board height - both require layout revision and are not pin-compatible replacements.

FAQ
What is the Zener voltage tolerance of SMBG5340A/TR13?
The SMBG5340A/TR13 has a Zener voltage tolerance of ±10%, meaning its regulated voltage falls between 9.0 V and 11.0 V when tested at 200 mA (IZT) and 25 °C. This tolerance is defined by the "A" suffix in the part number and is verified per JEDEC test methods in the Microsemi T4-LDS-0246-1 datasheet.
Is SMBG5340A/TR13 RoHS compliant?
Yes, SMBG5340A/TR13 is RoHS compliant, featuring annealed matte-tin plating per J-STD-020B Level 1 moisture sensitivity classification. The "e3" marking variant exists, but the TR13 tape-and-reel version supplied by Aetrix meets RoHS Directive 2011/65/EU without exemption requests.
What is the maximum surge current rating for SMBG5340A/TR13?
The SMBG5340A/TR13 supports a non-repetitive peak surge current (IZSM) of 10.7 A for an 8.3 ms half-sine waveform, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0246-1 datasheet. This rating applies under defined test conditions and validates suitability for IEC 61000-4-5 surge immunity.
How does the DO-215AA package of SMBG5340A/TR13 differ from DO-214AA?
The DO-215AA package of SMBG5340A/TR13 uses gull-wing leads for visible solder joints and lower tombstoning risk, whereas DO-214AA (used in SMBJ5340A) employs J-bend leads. DO-215AA has RθJL = 25 °C/W and RθJA = 90 °C/W on FR4; DO-214AA has RθJA = 100 °C/W - making SMBG5340A/TR13 thermally superior in lead-mounted configurations.
Can SMBG5340A/TR13 replace 1N5340B in existing designs?
Yes, SMBG5340A/TR13 is electrically equivalent to 1N5340B per JEDEC registration and Microsemi documentation, with identical VZ, IZT, ZZT, and IZSM. However, it is not a mechanical drop-in: SMBG5340A/TR13 requires SMT reflow and DO-215AA footprint, while 1N5340B uses axial T-18 mounting - redesign is needed for board layout and assembly.
