Product details
Overview
SMBG5363A/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 30 V, ±10% tolerance (A-suffix), 8.0 Ω dynamic impedance at 40 mA test current, and maximum regulator current of 158 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 SMBG5363A/TR13 datasheet, SMBG5363A/TR13 pinout, SMBG5363A/TR13 application, or SMBG5363A/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (RθJL = 25 °C/W), surge current rating (3.7 A), junction temperature range (–65 to +150 °C), and RoHS compliance status (non-RoHS, blank suffix).
Technical Context
This device functions as a voltage reference and clamp by operating in reverse breakdown with stable VZ across wide current (40 mA IZT, 158 mA IZM) and temperature (–65 to +150 °C) ranges. Its low dynamic impedance (8.0 Ω) ensures minimal voltage variation under load transients.
The DO-215AA gull-wing package enables visible solder joints and supports high-density PCB layouts. Thermal performance is defined by RθJL = 25 °C/W and RθJA = 90 °C/W on FR4 with recommended footprint, enabling 5.0 W dissipation only when lead temperature is maintained below 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 30 V ±10% - defines regulated output voltage in feedback or clamping circuits |
| Test Current (IZT) | 40 mA - operating point where VZ and ZZT are specified |
| Dynamic Impedance (ZZT) | 8.0 Ω - low AC impedance ensures stable regulation under varying load currents |
| Max Regulator Current (IZM) | 158 mA - maximum DC current before exceeding 5 W power limit at TL < 25 °C |
| Surge Current (IZSM) | 3.7 A - non-repetitive 8.3 ms half-sine peak withstand capability for transient suppression |
| Junction Temp Range | –65 to +150 °C - supports operation in industrial and automotive under-hood environments |
| Thermal Resistance J-to-L | 25 °C/W - critical for thermal design when using copper leads as heat sinks |

| High surge current rating | 3.7 A non-repetitive surge withstand supports IEC 61000-4-5 compliant transient protection |
| Stable VZ vs. current | Low dynamic impedance (8.0 Ω) minimizes regulation error across 10–150 mA operating range |
Applications
| Switch-Mode Power Supply Feedback | Overvoltage Clamp for Microcontroller I/O |
|---|---|
Use Scenario: Regulates output voltage in isolated flyback converter feedback path via optocoupler interface. IC Role / Device Role / Timing Role: Precision voltage reference establishing 30 V threshold for error amplifier comparison. Use Value: ±10% VZ tolerance and 8.0 Ω ZZT ensure <±1.5% output regulation accuracy across line/load/temperature. | Use Scenario: Protects 3.3 V or 5 V GPIO pins from accidental 24 V field wiring faults. IC Role / Device Role / Timing Role: Shunt clamp limiting pin voltage to 30 V during fault, diverting excess current to ground. Use Value: 3.7 A surge rating absorbs 100 ns–1 µs transients without degradation; cathode-band polarity ensures correct orientation. |
| Industrial Sensor Signal Conditioning | DC Link Voltage Monitoring Reference |
Use Scenario: Provides stable 30 V reference for ratiometric scaling of analog sensor outputs in 4–20 mA loop transmitters. IC Role / Device Role / Timing Role: Two-terminal voltage reference sourcing bias current for op-amp circuitry. Use Value: –65 to +150 °C operating range and low tempco support accuracy in uncontrolled ambient environments. | Use Scenario: Scales high-voltage DC bus (e.g., 300–800 V) to microcontroller ADC input using resistive divider with Zener clamp. IC Role / Device Role / Timing Role: Overvoltage limiter protecting ADC input against divider ratio drift or open-circuit failure. Use Value: 158 mA IZM allows sustained clamping during prolonged overvoltage events without thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5363B | Through-hole DO-41 package; identical VZ, IZT, ZZT, and IZM; same ±10% tolerance | Requires axial-leaded PCB layout and wave soldering; no gull-wing visual inspection benefit | Select when legacy through-hole assembly or socketing is required; not suitable for high-density SMT designs. |
| SMBG5363B | Same DO-215AA package; ±5% VZ tolerance (tighter); 8.0 Ω ZZT; identical IZM and surge rating | Higher cost due to tighter tolerance; preferred where regulation accuracy >±10% is mandatory | Select when system-level voltage accuracy demands ±5% VZ stability; requires tighter BOM control. |
Compared with SMBG5363A/TR13, 1N5363B offers identical electrical behavior but mandates through-hole assembly, while SMBG5363B provides improved voltage accuracy at the cost of tighter tolerance control and higher unit price-both require no circuit redesign but differ in manufacturability and precision trade-offs.

FAQ
What is the Zener voltage tolerance for SMBG5363A/TR13?
The SMBG5363A/TR13 has a Zener voltage tolerance of ±10%, indicated by the "A" suffix in the part number. This means its measured VZ falls between 27.0 V and 33.0 V at 40 mA test current and 25 °C. The tolerance directly impacts regulation accuracy in feedback networks and must be accounted for in worst-case circuit analysis.
Is SMBG5363A/TR13 RoHS compliant?
No, SMBG5363A/TR13 is not RoHS compliant. The absence of an "e3" suffix indicates standard Sn/Pb plating. For RoHS-compliant alternatives, select parts with the "e3" suffix (e.g., SMBG5363Be3), which use matte-tin plating and meet EU Directive 2011/65/EU requirements.
What is the maximum power dissipation of SMBG5363A/TR13?
SMBG5363A/TR13 is rated for 5.0 W off-state power dissipation at lead temperature (TL) < 25 °C. At ambient temperature (TA) = 25 °C on FR4 board, derated power is 1.38 W. Effective thermal design requires maintaining TL ≤ 25 °C via copper pour or thermal vias to sustain full 5 W operation.
How does the DO-215AA package of SMBG5363A/TR13 differ from DO-214AA?
The DO-215AA package of SMBG5363A/TR13 uses gull-wing leads for visible solder joints and lower profile, whereas DO-214AA (SMBJ series) uses J-bend leads. Both share similar outline dimensions, but DO-215AA's gull-wing form improves solder joint inspection and reduces assembly defects in high-volume SMT lines.
Can SMBG5363A/TR13 replace 1N5363B in existing designs?
Yes, SMBG5363A/TR13 is electrically equivalent to 1N5363B per Microsemi documentation and can replace it in new designs. However, direct substitution requires PCB footprint revision from DO-41 to DO-215AA; no circuit changes are needed, but mechanical layout and assembly process must be updated for surface-mount compatibility.
