Product details
Overview
SMBG5362A/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 28 V, ±10% tolerance, 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 SMBG5362A/TR13 datasheet, SMBG5362A/TR13 pinout, SMBG5362A/TR13 application, or SMBG5362A/TR13 equivalent, this page provides verified electrical parameters, thermal derating behavior, JEDEC-compliant Zener characteristics, RoHS status (non-RoHS, Sn/Pb plating), and direct alternatives with documented voltage/tolerance/power differences.
Technical Context
This device functions as a two-terminal voltage reference operating in reverse breakdown, maintaining stable output voltage across wide current (50 mA to 130 mA) and temperature (–65 °C to +150 °C) ranges. Its 28 V nominal Zener voltage is specified at 50 mA (IZT), with 6.0 Ω dynamic impedance (ZZT) confirming low AC impedance near regulation point.
Thermal design relies on junction-to-lead resistance of 25 °C/W and junction-to-ambient resistance of 90 °C/W on FR4 board; full 5.0 W dissipation is only valid when lead temperature (TL) remains ≤25 °C, dropping to 1.38 W at 25 °C ambient with recommended footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 28 V ±10% at 50 mA - defines regulated output level with ±2.8 V tolerance band |
| Power Dissipation (PD) | 5.0 W @ TL ≤ 25 °C - requires thermal management via PCB copper or heatsinking |
| Dynamic Impedance (ZZT) | 6.0 Ω @ IZT = 50 mA - ensures minimal voltage variation under small-signal AC load changes |
| Max Regulator Current (IZM) | 130 mA - sets upper DC current limit before exceeding 5 W rating at high-end VZ (30.8 V) |
| Junction Temperature Range | –65 °C to +150 °C - supports operation in industrial and automotive under-hood environments |
| Surge Current (IZSM) | 3.9 A (8.3 ms half-sine) - withstands transient overvoltage events without failure |
| Reverse Leakage (IR) | 0.5 µA @ VR = 20.1 V - confirms low off-state power loss in standby mode |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; anode and cathode terminals are accessible via solderable gull-wing leads. Moisture sensitivity level is IPC/JEDEC Level 1 - no dry pack required prior to reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to circuit common; reverse-biased operation requires cathode at higher potential |
| Cathode | Regulated output node | Banded end; held at stable 28 V relative to anode during breakdown conduction |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N53xxB equivalence | Identical electrical specs and test methods to legacy 1N5362B - enables drop-in replacement in existing designs |
| Gull-wing lead form | Enables visual solder joint inspection and reliable reflow attachment on high-density PCBs |
| Level 1 moisture sensitivity | Eliminates baking requirement before assembly - reduces manufacturing cost and cycle time |
| High surge current rating | 3.9 A non-repetitive surge capability protects downstream circuitry from line transients |
| Stable VZ vs. temperature | Low TCZ (typical <0.07 %/°C for 28 V part) minimizes drift across –65 °C to +150 °C range |
Applications

Use Scenario: Supplies stable bias voltage to bridge sensors or analog front-ends in PLC modules. IC Role / Device Role / Timing Role: Precision voltage source for excitation of resistive transducers. Use Value: Junction temperature range (–65 °C to +150 °C) and low VZ drift support operation in uncontrolled enclosures. | Use Scenario: Used with resistor dividers to generate custom reference voltages in ADC/DAC circuits.

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 28 V ±10%, 5 W, DO-204AL axial package - identical electrical specs but through-hole mounting | Requires PCB through-hole layout and wave soldering; not suitable for SMT-only production | Select when legacy through-hole design or manual prototyping is preferred |
| SMBG5362B | Same 28 V ±5%, 5 W, DO-215AA package - tighter tolerance but lower IZM (120 mA vs. 130 mA) | Higher precision regulation needed where ±5% VZ stability is critical (e.g., calibration references) | Select when tighter voltage tolerance outweighs 10 mA IZM reduction |
Compared with SMBG5362A/TR13, 1N5362B offers identical regulation performance but mandates through-hole assembly, while SMBG5362B trades 10 mA IZM for ±5% VZ accuracy - making SMBG5362A/TR13 optimal for cost-sensitive SMT power supplies requiring ±10% tolerance.

FAQ
What is the Zener voltage tolerance of SMBG5362A/TR13?
The SMBG5362A/TR13 has a Zener voltage tolerance of ±10%, meaning its regulated voltage falls between 25.2 V and 30.8 V at the specified test current of 50 mA. This tolerance is indicated by the "A" suffix in the part number per Microsemi's nomenclature. The device maintains this specification across its full operating temperature range of –65 °C to +150 °C, and SMBG5362A/TR13 is rated for 5.0 W dissipation when lead temperature remains at or below 25 °C.
Is SMBG5362A/TR13 RoHS compliant?
No, SMBG5362A/TR13 is not RoHS compliant. The "A" suffix indicates Sn/Pb (tin-lead) plating, whereas RoHS-compliant versions use the "e3" suffix (e.g., SMBG5362Be3). The datasheet explicitly states that blank or "A" suffix parts are non-RoHS compliant, and SMBG5362A/TR13 falls into this category. For RoHS requirements, engineers must select the e3 variant or verify compliance status with current Microchip documentation before design-in.
What is the maximum continuous current SMBG5362A/TR13 can handle?
The maximum continuous regulator current (IZM) for SMBG5362A/TR13 is 130 mA, calculated based on its 5.0 W power rating and the high-end Zener voltage (30.8 V) within its ±10% tolerance. This value assumes proper thermal management - specifically, that the lead temperature (TL) does not exceed 25 °C. At 25 °C ambient on a standard FR4 board, the usable IZM drops to approximately 49 mA due to thermal derating, so SMBG5362A/TR13 must be applied with appropriate copper area or heatsinking to sustain full-rated current.
How does SMBG5362A/TR13 compare to the older 1N5362B diode?
SMBG5362A/TR13 is the surface-mount DO-215AA gull-wing equivalent of the through-hole 1N5362B (DO-204AL), sharing identical electrical characteristics including 28 V ±10% Zener voltage, 5.0 W power rating, and 6.0 Ω dynamic impedance. The key difference is packaging: SMBG5362A/TR13 enables automated SMT assembly and visual solder inspection, while 1N5362B requires through-hole placement and wave soldering. Both are manufactured to JEDEC standards and exhibit identical surge and thermal performance.
What is the thermal resistance from junction to ambient for SMBG5362A/TR13?
The junction-to-ambient thermal resistance (RθJA) for SMBG5362A/TR13 is 90 °C/W when mounted on a standard FR4 printed circuit board with 1 oz copper and Microsemi's recommended pad layout. This value assumes natural convection cooling and defines the temperature rise above ambient per watt dissipated. For example, at 1.38 W dissipation (the ambient-rated power on FR4), junction temperature rises ~124 °C above ambient - underscoring why SMBG5362A/TR13 is rated for full 5.0 W only when lead temperature is controlled to ≤25 °C.
