Product details
Overview
SMBG5341AE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 6.2 V, ±10% tolerance (A suffix), and maximum Zener current of 765 mA at 25 °C. It uses DO-215AA gull-wing package, supports visible solder joints, and operates across –65 °C to +150 °C junction temperature range. It serves as a precision voltage reference in power supply feedback loops.
For engineers reviewing the SMBG5341AE3/TR13 datasheet, SMBG5341AE3/TR13 pinout, SMBG5341AE3/TR13 application, or SMBG5341AE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (RθJL = 25 °C/W), surge current rating (12.4 A), dynamic impedance (1.0 Ω), and RoHS-compliant matte-tin plating.
Technical Context
This device functions as a two-terminal voltage regulator operating in reverse-biased breakdown mode. Its Zener voltage is specified at 200 mA test current (IZT) and exhibits low dynamic impedance (1.0 Ω) near the knee, enabling stable regulation under varying load currents.
The SMBG5341AE3/TR13 features a moisture sensitivity level (MSL) 1 rating per IPC/JEDEC J-STD-020B, eliminating dry-pack requirements. Its gull-wing leads provide mechanical robustness and optical solder-joint inspection capability on FR4 PCBs with recommended footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V ±10% at IZT = 200 mA - defines regulated output voltage with bounded deviation for feedback accuracy |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - sets maximum continuous DC power handling with adequate heat sinking |
| Max Regulator Current (IZM) | 765 mA - determines maximum steady-state current before thermal derating or failure |
| Dynamic Impedance (ZZT) | 1.0 Ω at IZT = 200 mA - indicates low AC impedance for minimal output voltage variation under ripple |
| Surge Current (IZSM) | 12.4 A (8.3 ms half-sine) - enables transient overvoltage clamping without degradation |
| Junction Temperature Range | –65 °C to +150 °C - supports operation in automotive under-hood and industrial ambient environments |
| Thermal Resistance (RθJL) | 25 °C/W - quantifies junction-to-lead thermal path efficiency for PCB-level thermal design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5341B | Same VZ, IZT, ZZT, and PD; axial T-18 package instead of DO-215AA | Requires through-hole assembly and larger board area; not suitable for high-density SMT layouts | Select when legacy through-hole manufacturing or manual prototyping is used |
| SMBJ5341B | Identical electrical specs but J-bend (DO-214AA) lead form; RθJA = 90 °C/W same, but RθJL not specified | Lacks gull-wing visibility; less optimal for automated optical inspection of solder joints | Select when existing DO-214AA footprint is fixed and visual inspection is not required |
Compared with SMBG5341AE3/TR13, 1N5341B requires PCB redesign for through-hole mounting, while SMBJ5341B retains SMT compatibility but sacrifices solder-joint visibility and lacks published RθJL - making SMBG5341AE3/TR13 preferable for thermally demanding, high-reliability SMT applications.

FAQ
What is the Zener voltage tolerance of SMBG5341AE3/TR13?
The SMBG5341AE3/TR13 has a Zener voltage tolerance of ±10%, indicated by the "A" suffix in its part number. This means its breakdown voltage is guaranteed between 5.58 V and 6.82 V when measured at 200 mA test current and 25 °C lead temperature. The tolerance directly impacts regulation accuracy in feedback and reference applications.
Does SMBG5341AE3/TR13 require dry packing before reflow soldering?
No, SMBG5341AE3/TR13 does not require dry packing. It carries a moisture sensitivity level (MSL) rating of Level 1 per IPC/JEDEC J-STD-020B, meaning it can be stored indefinitely at ≤30 °C/60% RH without baking. This eliminates pre-reflow moisture removal steps in standard SMT lines.
What is the maximum surge current rating for SMBG5341AE3/TR13?
The SMBG5341AE3/TR13 has a maximum non-repetitive Zener surge current (IZSM) of 12.4 A for an 8.3 ms half-sine waveform. This rating is verified per manufacturer test conditions and enables reliable transient suppression in DC power rails without permanent parameter shift.
How does the DO-215AA gull-wing package benefit SMBG5341AE3/TR13 in production?
The DO-215AA gull-wing package of SMBG5341AE3/TR13 allows full optical inspection of solder joints after reflow, reducing field failures from insufficient wetting or bridging. Its 25 °C/W junction-to-lead thermal resistance also supports efficient heat transfer to the PCB copper, enhancing power handling reliability.
Is SMBG5341AE3/TR13 compatible with JEDEC-standard 1N5341B designs?
Yes, SMBG5341AE3/TR13 is electrically and functionally equivalent to 1N5341B per Microsemi documentation, sharing identical VZ, IZT, ZZT, and PD. However, SMBG5341AE3/TR13 uses surface-mount DO-215AA packaging versus axial T-18, so PCB layout must be updated for gull-wing footprint and reflow profile.
