Product details
Overview
SMBG5354A/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 17 V, ±10% tolerance (A suffix), 70 mA test current (IZT), and 2.5 Ω dynamic impedance (ZZT) at IZT - used for precision voltage regulation in power supply feedback loops, overvoltage protection, and reference circuits.
For engineers reviewing the SMBG5354A/TR13 datasheet, SMBG5354A/TR13 pinout, SMBG5354A/TR13 application, or SMBG5354A/TR13 equivalent, this page delivers verified electrical specs, DO-215AA gull-wing package details, thermal derating behavior, surge current capability (5.8 A), and direct alternatives with documented voltage/tolerance/power differences.
Technical Context
This device operates as a reverse-biased silicon Zener diode with sharp knee characteristics at 70 mA test current and exhibits low dynamic impedance (2.5 Ω) to maintain stable regulation across load variations. Its junction-to-lead thermal resistance is 25 °C/W, enabling effective heat transfer to PCB copper when mounted per recommended footprint.
The SMBG5354A/TR13 is rated for 5.0 W at TL < 25 °C, derates linearly above that temperature, and withstands non-repetitive 8.3 ms half-sine surge currents up to 5.8 A - validated under JEDEC-standard test conditions per MIL-STD-750.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 17 V ±10% - defines regulated output voltage range (15.3–18.7 V) at 70 mA bias. |
| Test Current (IZT) | 70 mA - operating point where VZ and ZZT are specified; sets minimum stable regulation current. |
| Dynamic Impedance (ZZT) | 2.5 Ω - small-signal AC resistance in breakdown; determines regulation error vs. load current change. |
| Max Regulator Current (IZM) | 5.8 A - maximum DC current at rated power; derived from P = VZM × IZM (VZM = 18.7 V). |
| Thermal Resistance (RθJL) | 25 °C/W - enables thermal design using lead-to-PCB conduction; supports 5 W operation with adequate copper area. |
| Surge Current (IZSM) | 5.8 A (8.3 ms half-sine) - peak non-repetitive current handling for transient overvoltage suppression. |
| Junction Temperature Range | −65 to +150 °C - supports industrial and automotive under-hood environments without derating. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; terminals are anode and cathode only - no internal connections beyond the two leads. Moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1 (no dry pack required).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Reverse-bias terminal | Connected to higher potential in regulation mode; polarity must be observed to avoid forward conduction. |
| Anode | Reference/ground terminal | Typically tied to system ground or return path; completes Zener bias loop in shunt regulator configuration. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5354B equivalent | Identical electrical specs and test methods - allows drop-in replacement in legacy designs qualified to 1N5354B. |
| RoHS-compliant matte-tin plating | Meets IPC-J-STD-006 solderability requirements; compatible with Pb-free reflow profiles up to 260 °C for 10 s. |
| Level 1 moisture sensitivity | No baking or dry packing required before SMT assembly - reduces manufacturing overhead and floor-life constraints. |
| Gull-wing lead form | Enables visual solder joint inspection and improves mechanical reliability on FR4 boards versus J-bend packages. |
| High surge current rating | 5.8 A non-repetitive surge capacity supports robust transient immunity in 24 V industrial power rails. |
Applications
| Switch-Mode Power Supply Feedback | Overvoltage Clamp for 12–24 V Systems |
|---|---|

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 VZ (17 V), ±5% tolerance (B suffix), 70 mA IZT, 2.5 Ω ZZT - identical electrical specs but tighter voltage tolerance. | Used where tighter regulation accuracy is required; requires recalculating IZM (6.3 A) due to higher VZM (17.9 V). | Select 1N5354B when ±5% VZ stability is mandatory and board layout accommodates axial-leaded T-18 package. |
| SMBJ5354A | Same VZ (17 V), ±10% tolerance, but J-bend DO-214AA package - different thermal resistance (RθJA = 90 °C/W vs. 25 °C/W for SMBG). | Lower power density handling; suitable for lower-current applications where lead-frame conduction is not critical. | Choose SMBJ5354A only if existing footprint uses DO-214AA; avoid in high-current or thermally constrained layouts. |
Compared with SMBG5354A/TR13, 1N5354B offers tighter voltage control but requires axial mounting and higher IZM calculation, while SMBJ5354A sacrifices thermal performance for J-bend compatibility - SMBG5354A/TR13 uniquely balances gull-wing manufacturability, 25 °C/W RθJL, and 5 W power delivery.

FAQ
What is the Zener voltage tolerance for SMBG5354A/TR13?
The "A" suffix in SMBG5354A/TR13 indicates a ±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.
Does SMBG5354A/TR13 require dry packing before SMT assembly?
No - SMBG5354A/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it can be stored and assembled without dry packing or baking. This is explicitly stated in the "MECHANICAL and PACKAGING" section and confirmed by its "Level 1" classification on page 1 of the datasheet.
What is the maximum continuous power dissipation for SMBG5354A/TR13?
SMBG5354A/TR13 is rated for 5.0 W at lead temperature (TL) below 25 °C. When mounted on an FR4 board with recommended footprint, its power rating derates linearly above 25 °C, reaching ~1.38 W at 25 °C ambient - detailed in the "MAXIMUM RATINGS" table and Figure 1 (Power Derating Curve).
How does the DO-215AA package of SMBG5354A/TR13 differ from DO-214AA?
The DO-215AA gull-wing package of SMBG5354A/TR13 provides visible solder joints and lower thermal resistance (RθJL = 25 °C/W) compared to the J-bend DO-214AA (e.g., SMBJ5354A). This improves heat transfer to PCB copper and supports higher sustained power in compact layouts - per Mechanical and Packaging section on page 2.
Is SMBG5354A/TR13 RoHS compliant?
Yes - SMBG5354A/TR13 uses RoHS-compliant annealed matte-tin plating, as confirmed in the "FEATURES" list and "MECHANICAL and PACKAGING" section. The "e3" marking variant exists for full RoHS traceability, though the base part number SMBG5354A/TR13 meets RoHS Directive 2011/65/EU without requiring the e3 suffix.
