Product details
Overview
SMBG5340C/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 10 V, ±2% tolerance (C suffix), 75 mA maximum regulator current (IZM), and DO-215AA gull-wing package. It regulates voltage across broad operating current and temperature ranges (-65 °C to +150 °C) and withstands high surge stresses in power supply reference and overvoltage protection circuits.
For engineers reviewing the SMBG5340C/TR13 datasheet, SMBG5340C/TR13 pinout, SMBG5340C/TR13 application, or SMBG5340C/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (RθJL = 25 °C/W), surge current rating (IZSM = 8.6 A), moisture sensitivity level (MSL Level 1), and RoHS-compliant matte-tin plating.
Technical Context
This device operates as a precision voltage reference by maintaining stable reverse-bias breakdown at 10 V under regulated current (IZT = 125 mA). Its low dynamic impedance (ZZT = 2.5 Ω at IZT) ensures minimal voltage variation with load changes, while its 25 °C/W junction-to-lead thermal resistance supports reliable power dissipation when soldered to PCB copper.
The SMBG5340C/TR13 uses a void-free UL94V-0 epoxy case with cathode band polarity marking and gull-wing leads compatible with standard reflow profiles (260 °C for 10 s). It meets MIL-STD-750 method 1020 for ESD insensitivity and requires no dry pack due to MSL Level 1 classification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10 V ±2% at IZT = 125 mA - ensures tight regulation accuracy for reference and feedback loops. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - supports robust transient handling with adequate heat sinking on FR4 board. |
| Dynamic Impedance (ZZT) | 2.5 Ω at 125 mA - minimizes output voltage drift under varying load currents. |
| Max Regulator Current (IZM) | 75 mA - defines safe DC operating limit before thermal runaway at rated power. |
| Surge Current (IZSM) | 8.6 A (8.3 ms half-sine) - enables clamping of short-duration transients without failure. |
| Junction Temperature Range | -65 °C to +150 °C - allows deployment in automotive under-hood and industrial control environments. |
| Thermal Resistance (RθJL) | 25 °C/W - confirms efficient heat transfer from die to lead, critical for sustained 5 W operation. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5340B | Same 10 V ±5% tolerance, 5 W rating, axial DO-41 package - higher RθJA (125 °C/W) limits power handling on PCB. | Requires through-hole mounting and manual assembly - unsuitable for high-density SMT production. | Select only for legacy repair or prototyping where footprint compatibility is secondary to cost. |
| SMBJ5340C | Identical electrical specs and DO-214AA J-bend package - same RθJL (25 °C/W) but different pad layout and thermal path geometry. | Compatible with automated placement but requires revised stencil and footprint - not drop-in for SMBG layout. | Choose when existing design uses DO-214AA footprint and board space permits J-bend lead configuration. |
Compared with 1N5340B and SMBJ5340C, SMBG5340C/TR13 delivers identical regulation performance in a gull-wing DO-215AA package optimized for visual solder inspection, high-density routing, and MSL Level 1 handling - making it the preferred choice for new SMT designs requiring production scalability and field reliability.

FAQ
What is the Zener voltage tolerance of SMBG5340C/TR13?
The SMBG5340C/TR13 has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in the part number. This means its measured VZ falls within 9.8 V to 10.2 V at the specified test current of 125 mA and junction temperature of 25 °C. This tighter tolerance supports precision reference applications where stability across temperature and current is critical, unlike the ±5% (B suffix) or ±10% (A suffix) variants in the same SMBG53xx family.
Does SMBG5340C/TR13 require dry packing before reflow soldering?
No, SMBG5340C/TR13 does not require dry packing prior to reflow soldering. It is rated MSL Level 1 per IPC/JEDEC J-STD-020B, meaning it has unlimited floor life at ≤30 °C/60% RH and can be processed directly from tape-and-reel without baking. This simplifies SMT line logistics and eliminates moisture-related popcorning risks - a key advantage over higher-MSL discrete components.
What is the maximum surge current rating for SMBG5340C/TR13?
The SMBG5340C/TR13 has a maximum non-repetitive Zener surge current (IZSM) of 8.6 A for an 8.3 ms half-sine waveform. This rating is verified per Microsemi's characterization and reflects its ability to absorb transient energy without parametric shift or catastrophic failure - essential for protecting downstream circuitry in automotive load-dump or industrial switching surge scenarios.
How does the DO-215AA package of SMBG5340C/TR13 differ from DO-214AA?
The DO-215AA package used by SMBG5340C/TR13 features gull-wing leads, whereas DO-214AA (used by SMBJ53xx devices) uses J-bend leads. Gull-wing geometry enables direct visual inspection of solder fillets and better coplanarity control during reflow, improving first-pass yield. The pad layout, thermal path, and mechanical footprint differ - making them non-interchangeable without PCB revision.
Is SMBG5340C/TR13 RoHS compliant?
Yes, SMBG5340C/TR13 is RoHS compliant, as confirmed by the "e3" marking option and matte-tin plating specified in the datasheet. The "C" suffix denotes ±2% voltage tolerance, while RoHS compliance is inherent to the standard production version - no additional suffix is required. This satisfies EU Directive 2011/65/EU and related global environmental regulations for commercial and industrial electronics.
