Product details
Overview
SMBG5362BE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 28 V, ±5% tolerance (B suffix), RoHS-compliant matte-tin plating (e3), and DO-215AA gull-wing package. It regulates voltage across wide current and temperature ranges and withstands high surge stresses in power supply and protection circuits.
For engineers reviewing the SMBG5362BE3/TR13 datasheet, SMBG5362BE3/TR13 pinout, SMBG5362BE3/TR13 application, or SMBG5362BE3/TR13 equivalent, key selection criteria include Zener voltage (28 V), test current (50 mA), dynamic impedance (6.0 Ω), maximum regulator current (130 mA), and thermal resistance (90 °C/W junction-to-ambient).
Technical Context
This device operates as a precision voltage reference and overvoltage clamp in DC power rails, delivering stable regulation at 28 V with 50 mA test current and 6.0 Ω dynamic impedance near knee. Its DO-215AA gull-wing package enables visible solder joints and supports automated assembly on FR4 PCBs.
It exhibits low reverse leakage (≤0.5 µA at 20.1 V), high surge capability (3.9 A non-repetitive 8.3 ms half-sine), and moisture sensitivity level 1-no dry pack required. Thermal performance is defined by RθJA = 90 °C/W (FR4, 1 oz Cu) and RθJL = 25 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 28 V ±5% at 50 mA - defines precise clamping threshold for 24 V system protection |
| Maximum Power Dissipation | 5.0 W at TL < 25 °C - requires heatsinking or derating above ambient 25 °C |
| Dynamic Impedance (ZZT) | 6.0 Ω at 50 mA - ensures minimal voltage shift under load variation |
| Maximum Regulator Current (IZM) | 130 mA - sets upper limit for continuous Zener bias without exceeding 5 W |
| Surge Current (IZSM) | 3.9 A (8.3 ms half-sine) - supports transient overvoltage suppression per IEC 61000-4-5 |
| Reverse Leakage (IR) | ≤0.5 µA at 20.1 V - guarantees low standby power loss in high-impedance bias networks |
| Junction Temperature Range | –65 to +150 °C - enables operation in automotive under-hood and industrial environments |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; banded end is positive during reverse-bias operation. Leads are RoHS-compliant annealed matte-tin plated for solderability per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink in reverse bias | Connected to lower-potential node (e.g., ground or return path) when used as shunt regulator |
| Cathode | Current source in reverse bias | Banded terminal connected to higher-potential rail (e.g., 24 V input) for clamping or reference |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N53xxB equivalent | Direct functional replacement for legacy through-hole 1N5362B with identical electrical specs |
| Gull-wing lead form | Enables optical inspection of solder joints and reduces tombstoning risk on fine-pitch layouts |
| Moisture Sensitivity Level 1 | No dry pack or baking required before reflow-reduces manufacturing overhead |
| High surge current rating | 3.9 A peak allows single-device transient suppression without external series impedance |
| Low dynamic impedance | 6.0 Ω stabilizes output voltage against ripple and load transients in feedback paths |
Applications
| Industrial Power Supply Regulation | Automotive ECU Overvoltage Clamp |
|---|---|

IC Role / Device Role / Timing Role: Shunt voltage regulator maintaining reference integrity for ADCs and analog comparators. Use Value: Maintains ≤±2% output deviation across –40 to +105 °C and 10–130 mA load range due to low ZZT and wide IZ operating window. |

Use Scenario: Generating calibrated 28 V reference in bench multimeter calibration circuitry. IC Role / Device Role / Timing Role: Low-drift, low-noise voltage standard traceable to primary standards. Use Value: ≤0.5 µA leakage at 20.1 V ensures negligible current error in high-impedance divider networks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5362B | Identical electrical specs, axial T-18 package with leads instead of gull-wing terminals | Requires through-hole assembly and manual soldering; not suitable for SMT-only lines | Select when legacy board repair or mixed-technology assembly is needed |
| SMBJ5362 | Same Zener voltage and power rating but in DO-214AA J-bend package; RθJA = 100 °C/W vs. 90 °C/W | Higher thermal resistance limits continuous current in compact layouts without copper pour | Select when footprint compatibility with SMBJ series is prioritized over thermal margin |
Compared with SMBG5362BE3/TR13, 1N5362B offers identical regulation but lacks SMT manufacturability, while SMBJ5362 trades 10 °C/W higher thermal resistance for alternate leadform compatibility-neither is pin-compatible, but both serve overlapping voltage-reference roles.

FAQ
What is the Zener voltage tolerance for SMBG5362BE3/TR13?
The 'B' suffix in SMBG5362BE3/TR13 specifies ±5% Zener voltage tolerance, meaning its breakdown voltage is guaranteed between 26.6 V and 29.4 V at 50 mA test current and 25 °C. This tolerance is verified per JEDEC JESD201 stress testing and applies across the full operating temperature range of –65 to +150 °C.
Does SMBG5362BE3/TR13 require dry packing before reflow soldering?
No, SMBG5362BE3/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity level 1, confirmed in the official Microsemi datasheet. It may be stored and processed directly without baking or dry pack, simplifying SMT line logistics and eliminating moisture-related popcorning risk during reflow.
What is the maximum continuous Zener current for SMBG5362BE3/TR13?
The maximum regulator current (IZM) for SMBG5362BE3/TR13 is 130 mA at TL < 25 °C. At higher lead temperatures, this value must be derated using the 90 °C/W junction-to-ambient thermal resistance and the 5.0 W power rating-exceeding 130 mA continuously risks thermal runaway without adequate copper pour or heatsinking.
How does SMBG5362BE3/TR13 compare to 1N5362B in electrical performance?
SMBG5362BE3/TR13 matches 1N5362B exactly in Zener voltage (28 V ±5%), dynamic impedance (6.0 Ω), reverse leakage (≤0.5 µA), and surge rating (3.9 A). The only differences are package (DO-215AA gull-wing vs. T-18 axial) and plating (RoHS matte-tin vs. Sn/Pb), making them functionally interchangeable where mounting permits.
What is the surge current waveform specification for SMBG5362BE3/TR13?
The non-repetitive peak surge current (IZSM) for SMBG5362BE3/TR13 is specified as 3.9 A for an 8.3 ms half-sine wave, per Note 4 on page 3 of the Microsemi datasheet T4-LDS-0246-1. This rating is validated under controlled lab conditions and supports IEC 61000-4-5 Level 3/4 transient immunity design.
