Product details
Overview
SMBG5354BE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 17 V, ±5% tolerance (B suffix), and maximum Zener current IZM of 70 mA at TL < 25 °C. It uses DO-215AA gull-wing package, supports visible solder joints, and is rated for junction temperatures from –65 °C to +150 °C. It serves as a precision voltage reference or overvoltage clamp in power supply regulation circuits.
For engineers reviewing the SMBG5354BE3/TR13 datasheet, SMBG5354BE3/TR13 pinout, SMBG5354BE3/TR13 application, or SMBG5354BE3/TR13 equivalent, key selection criteria include its 17 V Zener voltage, 70 mA maximum regulator current, 2.5 Ω dynamic impedance at 70 mA, RoHS-compliant matte-tin plating, and thermal resistance of 25 °C/W junction-to-lead.
Technical Context
This device operates in reverse-biased breakdown mode, delivering stable 17 V regulation across a wide operating current range (IZK = 1.0 mA to IZM = 70 mA) with minimal voltage drift versus temperature. Its low dynamic impedance (2.5 Ω) ensures tight regulation under varying load conditions.
The DO-215AA gull-wing package enables high-density PCB layout and visual solder inspection. With moisture sensitivity level 1 per J-STD-020B, it requires no dry-pack handling and withstands 260 °C solder reflow for 10 s.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 17 V at IZT = 70 mA - defines precise clamping/reference point in regulation circuits |
| Tolerance | ±5% (B suffix) - ensures predictable voltage window for design margining |
| Max Power Dissipation | 5.0 W at TL < 25 °C - requires thermal management when operated near full rating |
| Dynamic Impedance (ZZT) | 2.5 Ω at IZT = 70 mA - low AC impedance improves regulation stability under transient loads |
| Max Regulator Current (IZM) | 70 mA - sets upper DC current limit before thermal derating applies |
| Junction Temp Range | –65 °C to +150 °C - supports operation in automotive under-hood and industrial environments |
| Thermal Resistance (RθJL) | 25 °C/W - enables accurate junction temperature estimation from lead temperature |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; banded end is anode in forward bias but functions as cathode terminal in Zener regulation mode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (banded end) | Reference node for reverse-bias operation | Connected to lower-potential side of regulated circuit; polarity critical for correct Zener conduction |
| Cathode (non-banded end) | Input/regulated output node | Connected to higher-potential rail; carries full Zener current during regulation or clamping |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5354B equivalent | Identical electrical specs and test methods - enables drop-in replacement in legacy designs |
| RoHS-compliant matte-tin plating | Meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity - eliminates dry-pack requirement and simplifies handling |
| Gull-wing leads | Enables visual solder joint inspection and reliable reflow attachment on FR4 boards |
| High surge current rating | 5.8 A non-repetitive half-sine (8.3 ms) - provides robust transient overvoltage protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5354B | Same 17 V, ±5%, 5 W rating; axial T-18 package instead of DO-215AA surface mount | Requires through-hole PCB assembly; not suitable for high-density SMT layouts | Select when legacy through-hole manufacturing or manual prototyping is used |
| SMBJ5354B | Same electrical specs; DO-214AA (J-bend) package instead of DO-215AA (gull-wing) | Different footprint and solder profile; may require PCB redesign due to lead geometry and thermal pad layout | Select when existing DO-214AA land pattern is standardized and gull-wing inspection is not required |
Compared with SMBG5354BE3/TR13, 1N5354B offers identical regulation performance but mandates through-hole assembly, while SMBJ5354B retains SMT compatibility at the cost of different mechanical mounting and thermal path characteristics - choice depends on board assembly method and optical inspection needs.

FAQ
What is the Zener voltage tolerance of SMBG5354BE3/TR13?
The SMBG5354BE3/TR13 has a ±5% Zener voltage tolerance, indicated by the "B" suffix in the part number. This means its measured VZ at 70 mA test current falls between 16.15 V and 17.85 V at TL = 25 °C. The tolerance remains valid across the full operating temperature range of –65 °C to +150 °C, as confirmed in the Electrical Characteristics table on page 3 of the Microsemi datasheet T4-LDS-0246-1.
Does SMBG5354BE3/TR13 require dry-pack handling?
No, SMBG5354BE3/TR13 does not require dry-pack handling. It is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it can be stored indefinitely at ambient conditions without baking prior to reflow. This is explicitly stated in the Applications/Benefits section and Maximum Ratings table of the Microsemi datasheet T4-LDS-0246-1.
What is the maximum surge current rating for SMBG5354BE3/TR13?
The SMBG5354BE3/TR13 has a maximum non-repetitive Zener surge current (IZSM) of 5.8 A for an 8.3 ms half-sine waveform, as specified in the Electrical Characteristics table on page 3 of the Microsemi datasheet T4-LDS-0246-1. This rating applies under defined test conditions and supports transient overvoltage protection in power electronics.
How does the DO-215AA package of SMBG5354BE3/TR13 differ from DO-214AA?
The DO-215AA package of SMBG5354BE3/TR13 features gull-wing leads enabling visible solder joint inspection, whereas DO-214AA (used in SMBJ5354B) has J-bend leads that are not visually inspectable post-reflow. Dimensionally, DO-215AA has slightly larger body dimensions and different lead pitch - requiring distinct PCB footprints and reflow profiles.
Is SMBG5354BE3/TR13 compatible with lead-free reflow processes?
Yes, SMBG5354BE3/TR13 is compatible with lead-free reflow processes. Its RoHS-compliant matte-tin plating and 260 °C solder temperature rating (10 s) meet standard Pb-free reflow profiles. The datasheet specifies this in the Maximum Ratings table and confirms compliance with MIL-STD-750 method 2026 for solderability.
