Product details
Overview
SMBG5350A/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 13 V, ±10% tolerance (A-suffix), 100 mA maximum regulator current (IZM), and DO-215AA gull-wing package. It regulates voltage across wide current and temperature ranges in power supply reference and overvoltage protection circuits.
For engineers reviewing the SMBG5350A/TR13 datasheet, SMBG5350A/TR13 pinout, SMBG5350A/TR13 application, or SMBG5350A/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (RθJL = 25 °C/W), surge current rating (IZSM = 7.0 A), and RoHS-compliant matte-tin plating.
Technical Context
This device operates as a precision voltage reference in reverse-biased breakdown mode, maintaining stable output voltage under varying load and temperature conditions. Its dynamic impedance (ZZT = 2.5 Ω at IZT = 100 mA) ensures low regulation error across its operating current range.
The SMBG5350A/TR13 features a moisture sensitivity level (MSL) 1 rating per IPC/JEDEC J-STD-020B, eliminating dry-pack requirements, and withstands 260 °C soldering for 10 s. Its cathode band marking and gull-wing leads enable automated optical inspection and reliable solder joint visibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13 V ±10% - defines regulated output voltage at 100 mA test current; high-end limit is 14.3 V for worst-case design margin. |
| Power Dissipation (PD) | 5.0 W @ TL < 25 °C - requires thermal management on lead; derates to 1.38 W at 25 °C ambient on FR4 board. |
| Dynamic Impedance (ZZT) | 2.5 Ω @ IZT = 100 mA - low AC impedance ensures minimal voltage variation under ripple or transient load changes. |
| Max Regulator Current (IZM) | 100 mA - maximum continuous DC current before exceeding 5 W rating at VZ = 14.3 V (high-tolerance edge). |
| Surge Current (IZSM) | 7.0 A (8.3 ms half-sine) - supports transient overvoltage clamping without failure in surge-prone systems. |
| Thermal Resistance (RθJL) | 25 °C/W - enables direct heat transfer from junction to PCB lead; critical for sustained 5 W operation with heatsinking. |
| Reverse Leakage (IR) | 1.0 µA @ VR = 10.1 V - confirms sharp knee behavior and low standby power loss in bias networks. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by a band on the body. Leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 Method 2026. Weight: 0.1 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or lower-potential rail; forms return path for Zener current. |
| Cathode | Regulated output node | Banded terminal; supplies stable 13 V reference when reverse-biased; must be held positive relative to anode. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5350B equivalent | Identical electrical characteristics and testing to legacy through-hole 1N5350B, enabling drop-in replacement in upgraded designs. |
| MSL Level 1 rating | No dry-pack required prior to reflow; simplifies inventory handling and eliminates bake-out steps in SMT assembly. |
| Gull-wing lead form | Enables visual solder joint inspection and reduces tombstoning risk during reflow due to balanced thermal mass and surface tension. |
| High surge current capability | 7.0 A non-repetitive surge rating allows use in transient voltage suppression without external TVS stacking. |
| Low dynamic impedance | 2.5 Ω at 100 mA ensures <13 mV output shift per 1 mA load change-critical for precision analog references. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5350B | Through-hole DO-41 package; identical VZ, IZM, and ZZT specs; no MSL rating. | Requires axial-leaded PCB layout; unsuitable for high-density SMT production. | Choose for prototyping, repair, or legacy through-hole systems where rework access is prioritized over density. |
| SMBG5350B | Same DO-215AA package but ±5% VZ tolerance (B-suffix); higher IZM = 110 mA at VZ = 13.65 V. | Delivers tighter regulation (±0.65 V) for precision feedback loops; slightly higher power margin. | Choose when system-level accuracy demands tighter voltage tolerance and higher continuous current headroom. |
Compared with SMBG5350A/TR13, the 1N5350B offers identical regulation performance but lacks SMT compatibility and MSL-1 handling, while SMBG5350B improves voltage accuracy and current capacity at the cost of tighter tolerance-driven BOM control.

FAQ
What is the Zener voltage tolerance of SMBG5350A/TR13?
The SMBG5350A/TR13 has a ±10% Zener voltage tolerance, meaning its nominal 13 V rating spans 11.7 V to 14.3 V at 100 mA test current and 25 °C. This tolerance is defined by the "A" suffix in the part number and is verified per Microsemi's T4-LDS-0246-1 specification.
Does SMBG5350A/TR13 require dry packing before reflow soldering?
No, SMBG5350A/TR13 does not require dry packing. It carries an IPC/JEDEC J-STD-020B Moisture Sensitivity Level (MSL) 1 rating, confirming it is safe for standard reflow profiles-including peak temperatures up to 260 °C for 10 seconds-without preconditioning.
What is the maximum continuous Zener current for SMBG5350A/TR13?
The maximum continuous Zener current (IZM) for SMBG5350A/TR13 is 100 mA. This value is calculated at the upper limit of its voltage tolerance (14.3 V) to ensure the 5 W power rating is not exceeded, assuming adequate thermal conduction via the lead frame.
How does SMBG5350A/TR13 compare to the through-hole 1N5350B?
SMBG5350A/TR13 is the surface-mount DO-215AA equivalent of the through-hole 1N5350B, sharing identical electrical characteristics including VZ, IZM, ZZT, and surge ratings. The key differences are package form factor, gull-wing leads for SMT, and MSL-1 compliance-making SMBG5350A/TR13 suitable for automated high-density assembly.
What is the reverse leakage current specification for SMBG5350A/TR13?
The SMBG5350A/TR13 specifies a maximum reverse leakage current (IR) of 1.0 µA at a reverse test voltage (VR) of 10.1 V. This low leakage confirms stable operation below the Zener knee and minimizes quiescent power draw in bias networks.
