Product details
Overview
SMBG5362AE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with a nominal breakdown voltage of 28 V, ±10% tolerance (A suffix), 6.0 Ω dynamic impedance at 50 mA test current, and 170 A non-repetitive surge current rating. It operates in the DO-215AA gull-wing package and is used for precision voltage regulation in power supply feedback loops, overvoltage protection circuits, and reference voltage generation.
For engineers reviewing the SMBG5362AE3/TR13 datasheet, SMBG5362AE3/TR13 pinout, SMBG5362AE3/TR13 application, or SMBG5362AE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (25 °C/W junction-to-lead), surge current capability (170 A), RoHS-compliant matte-tin plating, and compatibility with automated SMT assembly on FR4 PCBs.
Technical Context
This device functions as a two-terminal voltage regulator in reverse-biased operation, maintaining stable output voltage across wide current (50 mA IZT to 130 mA IZM) and temperature (–65 °C to +150 °C) ranges. Its low dynamic impedance (6.0 Ω) ensures minimal voltage variation under load transients.
The DO-215AA gull-wing package provides visible solder joints, Level 1 moisture sensitivity (no dry pack required), and thermal performance optimized for lead-mounted dissipation-RθJL = 25 °C/W enables full 5 W power handling when leads are adequately heat-sunk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 28 V ±10% at 50 mA - defines regulated output level with predictable tolerance band for feedback or clamping use. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - maximum steady-state power handled with proper lead thermal path. |
| Dynamic Impedance (ZZT) | 6.0 Ω at IZT = 50 mA - low AC impedance ensures tight voltage regulation during current fluctuations. |
| Max Surge Current (IZSM) | 170 A (8.3 ms half-sine) - withstands high-energy transients without failure in protection circuits. |
| Junction Temperature Range | –65 °C to +150 °C - supports operation in industrial, automotive, and outdoor environments. |
| Thermal Resistance (RθJL) | 25 °C/W - enables full 5 W rating when mounted with thermally optimized PCB land pattern. |
| Reverse Leakage (IR) | 0.5 µA at 20.1 V - negligible standby current in high-impedance bias networks. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; anode and cathode terminals only. Designed for visible solder joint inspection and compatible with standard reflow profiles (260 °C peak, 10 s).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; referenced ground in Zener regulation | Connected to lower-potential node (e.g., ground or return path) during reverse-bias regulation. |
| Cathode | Current exit terminal in forward bias; Zener output node in reverse bias | Banded end; connected to regulated voltage node (e.g., feedback divider or clamp point). |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N53xxB Equivalent | Identical electrical specs and test methods to legacy through-hole 1N5362B-enables drop-in SMT upgrade. |
| RoHS Compliant Matte-Tin Plating | e3 suffix confirms annealed matte-tin finish per MIL-STD-750, method 2026-ensures reliable solderability and long-term intermetallic stability. |
| Level 1 Moisture Sensitivity | No dry pack or baking required before reflow-reduces manufacturing overhead and avoids moisture-induced popcorning. |
| Gull-Wing Lead Geometry | Visible solder fillets enable AOI and X-ray inspection-critical for high-reliability power supply and industrial control assemblies. |
| High Surge Withstand | 170 A non-repetitive surge rating (8.3 ms half-sine) supports robust transient suppression in DC bus protection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5362B | Same VZ (28 V), ±10%, but axial T-18 package; RθJA = 120 °C/W vs. 90 °C/W for SMBG5362AE3/TR13 | Through-hole mounting only; unsuitable for high-density SMT designs or automated assembly lines | Select 1N5362B only for legacy repair, prototyping, or low-volume through-hole builds where thermal derating is acceptable. |
| SMBJ5362B | Same VZ, ±5% (B suffix), DO-214AA J-bend package; higher ZZT = 7.0 Ω; IZSM = 160 A | Lower voltage tolerance improves regulation accuracy but requires tighter layout control due to J-bend footprint | Choose SMBJ5362B when ±5% tolerance is mandatory and J-bend reflow profile is validated; avoid if gull-wing inspection is required. |
Compared with 1N5362B and SMBJ5362B, SMBG5362AE3/TR13 uniquely combines RoHS compliance (e3), gull-wing visibility, ±10% tolerance for cost-sensitive regulation, and 170 A surge rating-making it optimal for production-grade SMT power management where manufacturability and transient robustness are prioritized.

FAQ
What is the Zener voltage tolerance for SMBG5362AE3/TR13?
The "A" suffix in SMBG5362AE3/TR13 specifies a ±10% Zener voltage tolerance, meaning its breakdown voltage is guaranteed between 25.2 V and 30.8 V at 50 mA test current and 25 °C. This tolerance aligns with JEDEC 1N5362B specifications and is confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0246-1 datasheet.
Does SMBG5362AE3/TR13 require dry packing before reflow soldering?
No, SMBG5362AE3/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it may be stored and processed without dry packing or baking. The device uses void-free epoxy encapsulation and meets Level 1 classification per the Mechanical and Packaging section on page 2 of the datasheet.
What is the maximum continuous Zener current for SMBG5362AE3/TR13?
The maximum dc regulator current (IZM) for SMBG5362AE3/TR13 is 130 mA, calculated per Note 3 in the datasheet using P = 5.0 W and VZM = 28 V × 1.1 = 30.8 V. This value assumes proper lead heat sinking; derating applies above 25 °C lead temperature.
Is SMBG5362AE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5362AE3/TR13 features RoHS-compliant matte-tin plating (e3 suffix) and is rated for 260 °C peak solder temperature for 10 seconds, fully compliant with IPC/JEDEC J-STD-020D lead-free reflow requirements as stated in the Maximum Ratings table on page 1.
How does the DO-215AA package differ from DO-214AA for SMBG5362AE3/TR13?
DO-215AA uses gull-wing leads enabling visual solder joint inspection, while DO-214AA uses J-bend leads. SMBG5362AE3/TR13 is exclusively in DO-215AA; the SMBJ5362B variant uses DO-214AA. Package dimensions, thermal resistance (RθJL = 25 °C/W), and pad layout differ-refer to page 5 of the datasheet for mechanical drawings.
