Product details
Overview
SMBG5340B/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 6.0 V ±5%, 200 mA test current (IZT), 1.0 Ω dynamic impedance (ZZT), 790 mA maximum regulator current (IZM), and DO-215AA gull-wing package. It regulates voltage in power supply reference and overvoltage protection circuits across industrial temperature range.
For engineers reviewing the SMBG5340B/TR13 datasheet, SMBG5340B/TR13 pinout, SMBG5340B/TR13 application, or SMBG5340B/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (RθJL = 25 °C/W), surge current rating (12.7 A), junction temperature range (–65 to +150 °C), and RoHS-compliant matte-tin plating.
Technical Context
This device operates as a precision voltage reference by maintaining stable reverse-bias conduction above its 6.0 V Zener voltage at IZT = 200 mA. Its low 1.0 Ω dynamic impedance ensures minimal voltage variation under load changes, while the DO-215AA gull-wing lead frame enables visible solder joint inspection and supports high-density PCB layouts.
The SMBG5340B/TR13 exhibits 790 mA maximum Zener current (IZM) at TL < 25 °C, derates linearly per Figure 1, and withstands non-repetitive 8.3 ms half-sine surge currents up to 12.7 A. Its moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1 - no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.0 V ±5% at IZT = 200 mA - defines precise regulation point for feedback loops |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management on FR4 board with recommended pad layout |
| Dynamic Impedance (ZZT) | 1.0 Ω at IZT = 200 mA - ensures <6 mV output shift per 6 mA load change |
| Max Regulator Current (IZM) | 790 mA - sets upper DC current limit before thermal runaway at rated power |
| Surge Current (IZSM) | 12.7 A (8.3 ms half-sine) - protects downstream circuitry from transient overvoltage events |
| Junction Temperature Range | –65 to +150 °C - supports operation in automotive under-hood and industrial control environments |
| Thermal Resistance (RθJL) | 25 °C/W - enables direct heat transfer to PCB copper pour or thermal pad |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5340B | Axial-leaded T-18 package; identical VZ, IZT, ZZT, and IZM specs; higher RθJA (125 °C/W vs. 90 °C/W). | Requires through-hole mounting and larger board area; unsuitable for high-density SMT designs. | Select when legacy through-hole assembly or manual repair is required; not suitable for new SMT-only designs. |
| SMBJ5340B | DO-214AA (J-bend) package; same electrical specs but different thermal profile (RθJL = 30 °C/W); identical RoHS compliance. | Lower thermal efficiency than SMBG5340B/TR13; may require larger copper area for same power dissipation. | Choose if existing footprint uses DO-214AA; verify thermal margin using RθJL = 30 °C/W in thermal simulation. |
Compared with 1N5340B and SMBJ5340B, SMBG5340B/TR13 delivers superior thermal performance (RθJL = 25 °C/W) and gull-wing visibility for AOI, making it optimal for high-reliability SMT power regulation where thermal management and process control are critical.

FAQ
What is the Zener voltage tolerance of SMBG5340B/TR13?
The SMBG5340B/TR13 has a Zener voltage tolerance of ±5%, specified as 6.0 V at 200 mA test current (IZT). This tolerance is confirmed in the Electrical Characteristics table on page 3 of the T4-LDS-0246-1 datasheet, where the "B" suffix denotes ±5% regulation accuracy. The actual measured VZ falls between 5.7 V and 6.3 V under standard test conditions.
Does SMBG5340B/TR13 support lead-free reflow soldering?
Yes, SMBG5340B/TR13 features RoHS-compliant matte-tin plating and is qualified for lead-free reflow soldering up to 260 °C for 10 seconds, per MIL-STD-750 Method 2026. Its DO-215AA gull-wing package maintains solderability and joint integrity under Pb-free thermal profiles, and its Level 1 moisture sensitivity eliminates pre-bake requirements.
What is the maximum continuous Zener current for SMBG5340B/TR13?
The maximum continuous Zener current (IZM) for SMBG5340B/TR13 is 790 mA when mounted on an FR4 PCB with the recommended pad layout and lead temperature (TL) maintained below 25 °C. At ambient temperature (TA = 25 °C), the usable IZM drops to approximately 1.38 W / 6.0 V ≈ 230 mA due to thermal derating - always consult Figure 1 (Power Derating Curve) for design margin.
How does SMBG5340B/TR13 compare to SMBJ5340B in thermal performance?
SMBG5340B/TR13 offers lower thermal resistance than SMBJ5340B: RθJL = 25 °C/W versus 30 °C/W. This 17% improvement allows more efficient heat transfer from junction to PCB copper, enabling higher sustained power dissipation or smaller thermal pads. Both share identical electrical specs, but SMBG5340B/TR13's gull-wing leads also support better AOI inspection than SMBJ5340B's J-bend configuration.
Is SMBG5340B/TR13 suitable for automotive applications?
Yes, SMBG5340B/TR13 is suitable for automotive applications including body control modules and sensor interfaces. Its –65 to +150 °C junction temperature range meets AEC-Q101 stress test requirements for discrete semiconductors, and its 12.7 A surge current rating handles load-dump and ISO 7637-2 pulse 5a/b events when properly decoupled.
