Product details
Overview
SMBG5341BE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 6.2 V, ±5% tolerance (B suffix), 200 mA test current (IZT), 1.0 Ω dynamic impedance (ZZT), and DO-215AA gull-wing package. It regulates voltage in power supply feedback loops, overvoltage clamping circuits, and reference voltage generation for industrial power converters.
For engineers reviewing the SMBG5341BE3/TR13 datasheet, SMBG5341BE3/TR13 pinout, SMBG5341BE3/TR13 application, or SMBG5341BE3/TR13 equivalent, this page delivers verified electrical specs, thermal derating behavior, RoHS-compliant plating details, and direct alternatives for voltage reference and transient suppression use cases.
Technical Context
This device operates in reverse breakdown to maintain stable voltage across wide current (1.0 mA to 765 mA) and temperature (-65 °C to +150 °C) ranges. Its low dynamic impedance (1.0 Ω at 200 mA) ensures minimal voltage variation under load transients.
The DO-215AA gull-wing package provides visible solder joints and 25 °C/W junction-to-lead thermal resistance. With 5.0 W power dissipation at TL < 25 °C and moisture sensitivity level 1, it supports reflow assembly without dry-pack preconditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V ±5% at 200 mA - defines precise regulation point for feedback networks |
| Power Dissipation (PD) | 5.0 W at lead temperature < 25 °C - requires thermal management on PCB for sustained operation |
| Dynamic Impedance (ZZT) | 1.0 Ω at IZT = 200 mA - enables tight voltage regulation under varying load currents |
| Max Regulator Current (IZM) | 765 mA - maximum continuous DC current before thermal runaway at rated power |
| Junction Temperature Range | -65 °C to +150 °C - supports operation in automotive under-hood and industrial control environments |
| Thermal Resistance (RθJL) | 25 °C/W - allows accurate junction temperature estimation from measured lead temperature |
| Reverse Leakage (IR) | 10 µA at VR = 3.0 V - ensures low standby power loss in high-impedance bias networks |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking. Two-terminal device: anode and cathode. Cathode is banded end; operated with banded end positive relative to anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; reference node in reverse-bias regulation | Connected to lower-potential side of regulated circuit; determines polarity of clamping action |
| Cathode | Current exit terminal in forward bias; Zener breakdown terminal in reverse bias | Banded end; connected to higher-potential side; establishes regulated output voltage referenced to anode |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5341B equivalent | Identical electrical characteristics and test methods - enables drop-in replacement in legacy designs |
| RoHS-compliant matte-tin plating | e3 suffix confirms lead-free finish compliant with IPC/JEDEC J-STD-020B Level 1 - no dry pack required |
| Gull-wing lead form | DO-215AA package enables visual solder joint inspection and reliable reflow yield on FR4 boards |
| High surge current rating | 12.4 A non-repetitive half-sine (8.3 ms) - withstands line transients in AC/DC front-end protection |
| Stable voltage vs. current | Low ZZT (1.0 Ω) and flat VZ vs. IZ curve - reduces output error in precision reference applications |
Applications
| Switch-Mode Power Supply Feedback | Overvoltage Clamp for Microcontroller I/O |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5341BRLG | Same 6.2 V ±5%, 5 W rating, DO-41 axial package; RθJA ≈ 50 °C/W vs. 90 °C/W for SMBG | Requires through-hole mounting; less suitable for high-density SMT layouts | Preferred where board space permits axial leads and manual assembly is acceptable |
| SMBJ5341B | Identical electrical specs but DO-214AA (J-bend) package; RθJL = 30 °C/W vs. 25 °C/W | Lower thermal performance; slightly reduced surge robustness due to different leadframe geometry | Valid alternative if existing footprint uses DO-214AA; verify thermal margin in high-power designs |
Compared with SMBG5341BE3/TR13, 1N5341BRLG offers identical regulation but demands through-hole layout and has inferior thermal resistance, while SMBJ5341B matches SMT compatibility but sacrifices 5 °C/W junction-to-lead efficiency and surge margin.

FAQ
What is the Zener voltage tolerance and test current for SMBG5341BE3/TR13?
The SMBG5341BE3/TR13 has a Zener voltage of 6.2 V with ±5% tolerance (denoted by the 'B' suffix) and is tested at 200 mA (IZT). This tolerance ensures predictable regulation within 5.9 V to 6.5 V at 200 mA, supporting stable feedback loop design in power converters where accuracy directly impacts output stability.
Does SMBG5341BE3/TR13 require dry-pack handling per J-STD-020?
No, SMBG5341BE3/TR13 has IPC/JEDEC moisture sensitivity level 1, meaning it can be stored indefinitely at ≤30 °C/60% RH without dry-pack desiccant or baking. This eliminates moisture-related reflow defects and simplifies manufacturing logistics for high-volume SMT lines.
What is the maximum surge current rating for SMBG5341BE3/TR13?
The SMBG5341BE3/TR13 supports a non-repetitive peak surge current (IZSM) of 12.4 A for an 8.3 ms half-sine waveform. This rating enables robust protection against line surges and inductive kickback in industrial power interfaces without requiring additional TVS devices.
How does the DO-215AA package of SMBG5341BE3/TR13 improve manufacturability?
The DO-215AA gull-wing package of SMBG5341BE3/TR13 provides visible solder joints for automated optical inspection (AOI), consistent coplanarity for high-yield reflow, and 25 °C/W junction-to-lead thermal resistance - enabling direct thermal coupling to copper pours for improved power handling versus J-bend alternatives.
Is SMBG5341BE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5341BE3/TR13 features RoHS-compliant matte-tin plating (e3 suffix) and is rated for 260 °C solder temperature at 10 seconds, fully compatible with standard lead-free reflow profiles (e.g., JEDEC J-STD-020 Class 3A). No special preheat or cooling ramp adjustments are needed.
