Product details
Overview
SMBG5354AE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 17 V, ±10% tolerance (A suffix), rated test current of 70 mA, maximum dynamic impedance of 2.5 Ω at IZT, and maximum regulator current of 5.8 A - used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5354AE3/TR13 datasheet, SMBG5354AE3/TR13 pinout, SMBG5354AE3/TR13 application, or SMBG5354AE3/TR13 equivalent, this page delivers verified electrical parameters, DO-215AA gull-wing package details, thermal derating behavior, RoHS-compliant matte-tin plating, and validated alternative parts for industrial power management designs.
Technical Context
This device operates in reverse-biased breakdown mode to maintain stable output voltage across wide current (IZK = 1 mA to IZM = 5.8 A) and temperature (–65 °C to +150 °C) ranges. Its low dynamic impedance (2.5 Ω) ensures minimal voltage variation under load transients.
Designed for surface-mount assembly on FR4 PCBs with recommended footprint, it achieves 5.0 W power dissipation at TL < 25 °C and 1.38 W at TA = 25 °C, with thermal resistance junction-to-lead of 25 °C/W and junction-to-ambient of 90 °C/W under standard mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 17 V ±10% - regulates at 15.3–18.7 V range under 70 mA test current |
| Power Dissipation (PD) | 5.0 W at lead temperature < 25 °C - requires thermal management above ambient |
| Dynamic Impedance (ZZT) | 2.5 Ω at 70 mA - limits output voltage deviation during current changes |
| Max Regulator Current (IZM) | 5.8 A - defines absolute DC current limit before thermal runaway |
| Reverse Leakage (IR) | 0.5 µA at 12.2 V - ensures low standby power loss in high-impedance bias networks |
| Junction Temperature Range | –65 °C to +150 °C - supports operation in automotive under-hood and industrial control environments |
| Thermal Resistance (RθJL) | 25 °C/W - enables accurate junction temperature estimation from lead temperature measurement |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; anode and cathode terminals are accessible via solderable gull-wing leads compliant with MIL-STD-750 method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Breakdown reference terminal | Connected to regulated output node; must be held positive relative to anode during regulation |
| Anode | Reference ground terminal | Typically tied to system ground or feedback divider low-side; completes Zener conduction path |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5354B equivalent | Identical electrical specs and test methods - enables legacy design reuse without requalification |
| RoHS-compliant matte-tin plating | Meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity - eliminates dry-pack requirement |
| Gull-wing lead form | Enables visual solder joint inspection and reliable reflow yield on fine-pitch PCBs |
| High surge current rating | 1000 A non-repetitive peak (8.3 ms half-sine) - withstands lightning-induced transients in AC/DC inputs |
| Low voltage drift vs. current | Stable VZ across 1 mA to 5.8 A - simplifies feedback network design in switching regulators |
Applications

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 ±10%, 5 W rating, axial T-18 package - no gull-wing SMT compatibility | Requires through-hole assembly; unsuitable for high-density PCB layouts | Select when legacy through-hole manufacturing or manual prototyping is required |
| SMBJ5354B | Identical electrical specs but J-bend DO-214AA package - different pad layout and thermal path | Higher RθJA (100 °C/W vs. 90 °C/W) reduces power handling on same PCB area | Choose only if existing DO-214AA footprint must be reused; verify thermal margin |
Compared with SMBG5354AE3/TR13, 1N5354B lacks SMT compatibility and SMBJ5354B offers lower thermal performance in identical board space - the SMBG5354AE3/TR13 remains optimal for new SMT designs requiring JEDEC-standard 5 W Zener regulation with visible solder joints.

FAQ
What is the Zener voltage tolerance for SMBG5354AE3/TR13?
The 'A' suffix in SMBG5354AE3/TR13 denotes ±10% Zener voltage tolerance, meaning its breakdown voltage is guaranteed between 15.3 V and 18.7 V at 70 mA test current and 25 °C. This tolerance is confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0246-1 datasheet, and applies across the full operating temperature range.
Does SMBG5354AE3/TR13 require dry packing before reflow soldering?
No, SMBG5354AE3/TR13 does not require dry packing prior to reflow. It carries IPC/JEDEC J-STD-020B moisture sensitivity level 1, verified per the manufacturer's documentation, allowing indefinite floor life at ≤30 °C/60% RH without baking - a direct result of its void-free thermosetting epoxy encapsulation.
What is the maximum surge current rating for SMBG5354AE3/TR13?
SMBG5354AE3/TR13 has a non-repetitive peak surge current (IZSM) rating of 1000 A for an 8.3 ms half-sine waveform, as specified in the Electrical Characteristics table. This value is measured under standardized test conditions and reflects the device's capability to absorb transient energy without failure in overvoltage protection applications.
How does the thermal resistance of SMBG5354AE3/TR13 affect PCB layout?
SMBG5354AE3/TR13 has RθJL = 25 °C/W and RθJA = 90 °C/W when mounted on FR4 with the recommended footprint. To sustain 5.0 W dissipation, the PCB must provide adequate copper area and thermal vias to keep lead temperature below 25 °C - otherwise, power must be derated per Figure 1 in the datasheet.
Is SMBG5354AE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5354AE3/TR13 features RoHS-compliant matte-tin plating and is qualified for lead-free reflow with peak solder temperature up to 260 °C for 10 seconds, as stated in the Maximum Ratings table. Its gull-wing geometry also supports uniform wetting and reliable joint formation under standard JEDEC J-STD-020 profiles.
