Product details
Overview
SMBG5362C/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 28 V, ±2% tolerance (C suffix), 6.0 Ω dynamic impedance at 50 mA test current, and maximum regulator current of 130 mA. It operates in the DO-215AA gull-wing package and is used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5362C/TR13 datasheet, SMBG5362C/TR13 pinout, SMBG5362C/TR13 application, or SMBG5362C/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (RθJL = 25 °C/W), surge current rating (IZSM = 3.9 A), and RoHS-compliant matte-tin plating per MIL-STD-750 method 2026.
Technical Context
This device functions as a two-terminal voltage reference operating in reverse breakdown, with cathode band marking polarity. Its low dynamic impedance (6.0 Ω) ensures stable regulation across load variations, while its 25 °C/W junction-to-lead thermal resistance supports reliable 5 W dissipation when soldered to PCB copper.
The SMBG5362C/TR13 meets JEDEC 1N5362B electrical equivalence and is rated for -65 °C to +150 °C junction temperature. It exhibits minimal voltage drift versus current and withstands non-repetitive 8.3 ms half-sine surges up to 3.9 A, verified per Microsemi T4-LDS-0246-1 Rev. 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 28 V ±2% at IZT = 50 mA - defines precise regulation point for feedback networks |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management on PCB for full-rated operation |
| Dynamic Impedance (ZZT) | 6.0 Ω at IZT = 50 mA - ensures low output impedance and tight regulation under varying load |
| Max Regulator Current (IZM) | 130 mA - sets upper limit for continuous Zener bias current without exceeding PD |
| Surge Current (IZSM) | 3.9 A (8.3 ms half-sine) - enables transient overvoltage clamping in protection circuits |
| Junction-to-Lead Thermal Resistance | 25 °C/W - allows direct thermal path to PCB copper for efficient heat removal |
| Moisture Sensitivity Level | Level 1 per J-STD-020B - no dry pack required prior to reflow soldering |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; terminals are anode and cathode only. Designed for visible solder joints and high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Regulated output node | Connected to reference point in feedback loop; must be held positive relative to anode |
| Anode | Return/ground reference | Common return path for Zener current; tied to system ground or low-side switch node |
Key Features
| Feature | Design Value |
|---|---|

| RoHS Compliant Matte-Tin Plating | Solderable per MIL-STD-750 method 2026 - supports lead-free reflow without intermetallic degradation |
| Gull-Wing Lead Geometry | Visible solder joints and mechanical stability - simplifies AOI inspection and improves board-level reliability |
| Level 1 Moisture Sensitivity | No dry pack required before assembly - reduces handling cost and eliminates bake step |
| High Surge Withstand | 3.9 A non-repetitive peak - protects downstream circuitry from line transients without external TVS |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5362B | Same VZ, ±5% tolerance (B suffix); identical DO-215AA package; non-RoHS Sn/Pb plating | Lower cost where RoHS compliance not mandated; slightly wider regulation band affects precision feedback | Select when legacy Sn/Pb assembly is used and ±5% tolerance suffices for target regulation accuracy |
| SMBG5362B | Same VZ, ±5% tolerance; RoHS-compliant matte-tin finish; otherwise identical electrical specs and package | Direct RoHS-compliant alternative with same thermal and surge performance but relaxed voltage tolerance | Choose when RoHS is required but tighter ±2% tolerance is unnecessary for application stability margin |
Compared with SMBG5362C/TR13, the 1N5362B offers lower-cost Sn/Pb assembly compatibility but sacrifices regulation precision, while SMBG5362B retains RoHS compliance and thermal performance at reduced voltage accuracy-making SMBG5362C/TR13 optimal for high-accuracy feedback and protection where ±2% VZ is critical.
