Product details
Overview
SMBG5352C/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 15 V, ±2% tolerance (C suffix), 2.5 Ω dynamic impedance at 75 mA test current, and maximum regulator current of 6.3 A under thermal lead conditions - used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5352C/TR13 datasheet, SMBG5352C/TR13 pinout, SMBG5352C/TR13 application, or SMBG5352C/TR13 equivalent, this page delivers verified electrical parameters, DO-215AA gull-wing package details, JEDEC 1N5352C-compliant characteristics, and real-world design implications for stable 15 V reference and clamping functions.
Technical Context
This device operates as a silicon planar Zener diode in reverse breakdown mode, delivering stable 15 V regulation across 1.0 mA to 6.3 A DC current range. Its low 2.5 Ω dynamic impedance 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 lead temperature <25 °C and withstands 8.3 ms half-sine surge currents up to 6.3 A. Cathode polarity is marked by a band; operation requires cathode-positive biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15 V ±2% at IZT = 75 mA - defines precise regulation point for feedback networks and reference circuits |
| Test Current (IZT) | 75 mA - standard operating point where VZ and ZZT are specified; sets minimum stable bias requirement |
| Dynamic Impedance (ZZT) | 2.5 Ω at 75 mA - determines output voltage ripple rejection and load regulation sensitivity |
| Maximum Regulator Current (IZM) | 6.3 A - peak continuous DC current supported with adequate heat sinking at TL < 25 °C |
| Power Dissipation (PD) | 5.0 W at TL ≤ 25 °C - thermal limit governed by junction-to-lead resistance (25 °C/W) |
| Reverse Leakage (IR) | 1.0 µA max at VR = 10.8 V - ensures low quiescent loss in high-impedance bias networks |
| Junction Temperature Range | –65 °C to +150 °C - supports operation in automotive under-hood and industrial control environments |
Pinout & Package
Package: DO-215AA gull-wing surface-mount plastic case (UL94V-0 epoxy), 0.1 g weight, moisture sensitivity level 1 (no dry pack required). Cathode indicated by band; banded end must be biased positive relative to anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node in Zener configuration | Connected to system ground or lower-potential rail; forms return path for regulation current |
| Cathode | Regulated output node | Banded terminal; supplies stable 15 V to feedback divider or clamp load when reverse-biased |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5352C equivalence | Identical electrical specs and test methods - enables drop-in replacement in legacy designs qualified to MIL-STD-750 |
| RoHS-compliant matte-tin plating | Meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity - eliminates bake requirements before reflow |
| Gull-wing lead geometry | Enables visual solder joint inspection and reliable reflow yield on standard SMT lines |
| High surge current rating | 6.3 A non-repetitive 8.3 ms half-sine - protects downstream circuitry against transient overvoltage events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5352C | Axial-leaded T-18 package; identical VZ, IZT, ZZT, and IZM; higher RθJA (125 °C/W vs. 90 °C/W) | Requires through-hole assembly; unsuitable for high-density SMT layouts | Select when legacy through-hole production or manual repair is required |
| SMBJ5352C | DO-214AA J-bend package; same electrical specs but different thermal profile (RθJA = 90 °C/W, RθJL = 25 °C/W); identical marking and RoHS compliance | Compatible with alternate SMT footprints; slightly reduced mechanical robustness in vibration-prone environments | Select when DO-214AA footprint is already standardized in design |
Compared with SMBG5352C/TR13, 1N5352C requires PCB redesign for through-hole mounting and offers inferior thermal performance in convection-cooled environments, while SMBJ5352C provides identical regulation performance in a mechanically distinct but electrically interchangeable SMT package.

FAQ
What is the Zener voltage tolerance for SMBG5352C/TR13?
The "C" suffix in SMBG5352C/TR13 specifies a ±2% Zener voltage tolerance at 75 mA test current. This yields a guaranteed VZ range of 14.7 V to 15.3 V under standard test conditions (TL = 30 °C), making SMBG5352C/TR13 suitable for applications demanding tighter regulation than ±5% (B suffix) or ±10% (A suffix) variants.
Does SMBG5352C/TR13 require dry packing before reflow soldering?
No - SMBG5352C/TR13 has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ambient conditions without baking. The DO-215AA package's void-free epoxy construction and Level 1 rating eliminate dry pack requirements, simplifying SMT line logistics for SMBG5352C/TR13.
What is the maximum surge current rating for SMBG5352C/TR13?
SMBG5352C/TR13 is rated for a non-repetitive peak surge current (IZSM) of 6.3 A, defined as the maximum current for an 8.3 ms half-sine waveform. This value is confirmed in the Electrical Characteristics table on page 3 of the Microsemi datasheet T4-LDS-0246-1, ensuring SMBG5352C/TR13 can absorb common power-line transients without degradation.
How does the thermal resistance of SMBG5352C/TR13 affect its power handling?
SMBG5352C/TR13 has a junction-to-lead thermal resistance (RθJL) of 25 °C/W and junction-to-ambient (RθJA) of 90 °C/W on FR4 with recommended footprint. At TL < 25 °C, it delivers full 5.0 W; above that, derating applies. This means SMBG5352C/TR13 must be mounted with proper copper pour and thermal vias to sustain continuous operation near its IZM limit.
Is SMBG5352C/TR13 compatible with lead-free reflow profiles?
Yes - SMBG5352C/TR13 features RoHS-compliant annealed matte-tin plating and is rated for solder temperatures up to 260 °C for 10 seconds, fully supporting industry-standard lead-free reflow profiles (e.g., JEDEC J-STD-020). The "e3" marking variant confirms compliance, and SMBG5352C/TR13 undergoes qualification per MIL-STD-750 method 2026 for solderability.
