Product details
Overview
SMBG5341C/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 6.2 V, ±2% tolerance (C 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 protection circuits, and reference voltage generation under varying load and temperature conditions.
For engineers reviewing the SMBG5341C/TR13 datasheet, SMBG5341C/TR13 pinout, SMBG5341C/TR13 application, or SMBG5341C/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current capability (12.4 A IZSM), thermal resistance (25 °C/W junction-to-lead), RoHS-compliant matte-tin plating, and visible gull-wing solder joints for automated optical inspection.
Technical Context
This device operates as a precision shunt regulator in reverse-biased mode, maintaining stable output voltage across wide operating 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 with load changes.
The DO-215AA gull-wing package enables high-density PCB layout with visible solder fillets and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity-no dry pack required. Thermal performance relies on junction-to-lead conduction (25 °C/W), not ambient dissipation, making it suitable for thermally constrained designs with adequate lead-frame heat sinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V ±2% at 200 mA - tight regulation for feedback references requiring <±124 mV error budget |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management via copper pour or heatsinked leads |
| Dynamic Impedance (ZZT) | 1.0 Ω at IZT = 200 mA - supports stable regulation under fast transient load steps |
| Max Surge Current (IZSM) | 12.4 A (8.3 ms half-sine) - withstands common power-line transients and ESD events |
| Junction Temp Range | -65 °C to +150 °C - qualified for industrial and automotive under-hood environments |
| Thermal Resistance (RθJL) | 25 °C/W - enables predictable thermal design when mounted per recommended footprint |
| Reverse Leakage (IR) | 10 µA max at VR = 3.0 V - ensures low quiescent current in standby-mode protection circuits |
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 annealed matte-tin plated, solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink terminal in reverse bias | Connected to lower-potential node (e.g., ground or return path) in shunt regulation |
| Cathode | Current source terminal in reverse bias | Banded end; connected to regulated voltage node (e.g., feedback divider or protected rail) |
Key Features
| Feature | Design Value |
|---|---|

| Moisture Sensitivity Level 1 | No dry pack or baking required before reflow - reduces manufacturing overhead and handling risk |
| Gull-wing lead form | Visible solder fillets enable AOI verification - improves yield in high-reliability SMT lines |
| Non-ESD-sensitive | Qualified per MIL-STD-750 Method 1020 - eliminates need for special ESD handling in assembly |
| High IZM rating | 765 mA maximum regulator current - supports robust overvoltage clamping without derating |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5341B | Same 6.2 V ±5%, 200 mA IZT, but wider tolerance; Sn/Pb plating only | Lacks RoHS compliance; higher VZ drift with temperature due to ±5% spec | Select when legacy Sn/Pb assembly is used and tighter tolerance is not required |
| SMBJ5341C | Identical electrical specs and RoHS finish, but DO-214AA J-bend package | Different footprint and thermal path (RθJA = 90 °C/W vs RθJL = 25 °C/W); no visible solder joint | Choose when board space allows J-bend mounting and lead-frame heat sinking is unavailable |
Compared with SMBG5341C/TR13, 1N5341B trades RoHS compliance and voltage precision for legacy compatibility, while SMBJ5341C retains identical regulation performance but shifts thermal reliance from lead conduction to ambient convection-requiring different PCB thermal design.

FAQ
What is the Zener voltage tolerance of SMBG5341C/TR13?
The SMBG5341C/TR13 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in the part number. This means its measured VZ at 200 mA falls between 6.076 V and 6.324 V at 25 °C. This tighter tolerance supports precision regulation tasks where 1% or better output stability is required, unlike ±5% (B suffix) or ±10% (A suffix) variants.
Does SMBG5341C/TR13 require dry packing before reflow soldering?
No, SMBG5341C/TR13 does not require dry packing. It carries IPC/JEDEC J-STD-020B Moisture Sensitivity Level 1 rating, meaning it can be stored indefinitely at ≤30 °C/60% RH without baking. This eliminates pre-reflow baking steps, reducing process complexity and avoiding thermal stress on the plastic encapsulant.
What is the maximum surge current rating for SMBG5341C/TR13?
The SMBG5341C/TR13 is rated for a maximum non-repetitive peak surge current (IZSM) of 12.4 A, specified for an 8.3 ms half-sine waveform. This value is derived from its 5 W power rating and 6.2 V Zener voltage, enabling reliable clamping of common power-line surges and inductive kickback events without parametric shift or failure.
How does the DO-215AA package of SMBG5341C/TR13 differ from DO-214AA?
The DO-215AA package of SMBG5341C/TR13 uses gull-wing leads for visible solder fillets and lower thermal resistance (RθJL = 25 °C/W), whereas DO-214AA (used in SMBJ5341C) employs J-bend leads with higher ambient-dependent dissipation (RθJA = 90 °C/W). Gull-wing mounting enables better thermal conduction through PCB copper and facilitates automated optical inspection.
Is SMBG5341C/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5341C/TR13 features RoHS-compliant matte-tin plating and is qualified for standard lead-free reflow profiles up to 260 °C for 10 seconds. Its void-free thermosetting epoxy body meets UL94V-0 flammability rating, ensuring mechanical integrity and intermetallic formation control during Pb-free soldering without delamination or popcorning.
