Product details
Overview
SMBG5363BE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 30 V, ±5% tolerance (B suffix), 8.0 Ω dynamic impedance at 40 mA test current, and maximum regulator current of 3.7 A at 25 °C. It operates in voltage regulation and overvoltage protection circuits for industrial power supplies and DC-DC converters.
For engineers reviewing the SMBG5363BE3/TR13 datasheet, SMBG5363BE3/TR13 pinout, SMBG5363BE3/TR13 application, or SMBG5363BE3/TR13 equivalent, this page delivers verified electrical parameters, DO-215AA gull-wing package details, JEDEC 1N5363B equivalence, thermal derating behavior, and RoHS-compliant matte-tin plating confirmation.
Technical Context
This device functions as a precision shunt voltage regulator, maintaining stable output voltage across wide operating current (40 mA IZT to 3.7 A IZM) and temperature (-65 °C to +150 °C) ranges. Its low dynamic impedance (8.0 Ω) ensures minimal voltage variation under load transients.
Designed for surface-mount assembly on FR4 PCBs with recommended footprint, it achieves 5.0 W power dissipation at lead temperature <25 °C or 1.38 W at ambient 25 °C, with thermal resistance junction-to-lead of 25 °C/W and junction-to-ambient of 90 °C/W under standard mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 30 V ±5% at 40 mA - defines regulated output voltage with tight tolerance for stable reference applications |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - supports high-energy transient clamping when adequately heat-sinked |
| Dynamic Impedance (ZZT) | 8.0 Ω at IZT = 40 mA - ensures low AC voltage variation during ripple suppression |
| Max Regulator Current (IZM) | 3.7 A - sets absolute DC current limit before thermal runaway under sustained overload |
| Reverse Leakage (IR) | 0.5 µA at VR = 21.6 V - guarantees minimal standby power loss in high-impedance bias networks |
| Thermal Resistance (RθJL) | 25 °C/W - enables accurate junction temperature prediction from measured lead temperature |
| Surge Current (IZSM) | 140 A (8.3 ms half-sine) - withstands common lightning-induced or inductive-switching transients |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; terminals are anode and cathode only - no internal circuitry or additional pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Regulated output node | Connected to positive rail; reverse-biased operation requires cathode at higher potential than anode |
| Anode | Reference/ground node | Typically tied to system ground or lower-potential rail; completes current path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5363B equivalence | Identical electrical specs and test methods - enables drop-in replacement in legacy designs |
| RoHS-compliant matte-tin plating | Meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity - eliminates dry-pack requirement |
| Gull-wing lead geometry | Enables visual solder joint inspection and reliable reflow yield on automated SMT lines |
| High surge current rating | 140 A non-repetitive peak - protects downstream circuitry from IEC 61000-4-5 level 4 surges |
| Stable voltage vs. current | Low ZZT (8.0 Ω) and minimal VZ drift - maintains regulation accuracy across 10:1 current range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5363B | Same electrical specs, axial T-18 package - no gull-wing leads or SMT compatibility | Requires through-hole assembly; unsuitable for high-density PCBs | Select when legacy through-hole manufacturing or manual prototyping is required |
| SMBJ5363B | Identical VZ, IZM, and tolerance but in DO-214AA J-bend package - different thermal resistance (RθJA = 100 °C/W) | Lower power derating on FR4 board due to higher junction-to-ambient resistance | Select when existing DO-214AA footprint is fixed and thermal margin allows 1.25 W at TA = 25 °C |
Compared with SMBG5363BE3/TR13, 1N5363B requires PCB redesign for through-hole mounting while SMBJ5363B offers same regulation performance but reduced thermal efficiency on standard FR4 - SMBG5363BE3/TR13 delivers optimal balance of SMT compatibility, 5 W capability, and visual solder inspection.

FAQ
What is the Zener voltage tolerance for SMBG5363BE3/TR13?
The "B" suffix in SMBG5363BE3/TR13 indicates ±5% Zener voltage tolerance, meaning its regulated voltage falls between 28.5 V and 31.5 V at the specified test current of 40 mA. This tolerance is confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0246-1 datasheet. The SMBG5363BE3/TR13 maintains this specification across its full operating temperature range of -65 °C to +150 °C.
Is SMBG5363BE3/TR13 RoHS compliant?
Yes, SMBG5363BE3/TR13 is RoHS compliant, as indicated by the "e3" suffix in its part number. The device uses annealed matte-tin plating per MIL-STD-750 Method 2026 and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity - eliminating the need for dry-pack packaging. This compliance is explicitly stated in the Mechanical and Packaging section of the official Microsemi datasheet for SMBG5333B–SMBG5388B.
What is the maximum power dissipation of SMBG5363BE3/TR13 on a standard FR4 PCB?
When mounted on a standard FR4 PCB with 1 oz copper and the recommended footprint, SMBG5363BE3/TR13 delivers 1.38 W at 25 °C ambient temperature. Its full 5.0 W rating applies only when lead temperature is maintained below 25 °C - requiring external heatsinking or forced convection. This derating behavior is defined in Note 2 of the Maximum Ratings table on page 1 of the Microsemi datasheet.
Does SMBG5363BE3/TR13 have the same specifications as 1N5363B?
Yes, SMBG5363BE3/TR13 is electrically equivalent to JEDEC-registered 1N5363B, with identical Zener voltage, dynamic impedance, leakage current, and surge ratings. The only differences are mechanical: SMBG5363BE3/TR13 uses a DO-215AA gull-wing SMT package, whereas 1N5363B uses an axial T-18 leaded package. This equivalence is confirmed in the product description on page 1 of Microsemi's T4-LDS-0246-1 datasheet.
What is the surge current rating for SMBG5363BE3/TR13?
SMBG5363BE3/TR13 has a non-repetitive peak surge current (IZSM) rating of 140 A for an 8.3 ms half-sine waveform, as specified in the Electrical Characteristics table on page 3 of the Microsemi datasheet. This rating enables robust protection against IEC 61000-4-5 and ISO 7637-2 transients when used with appropriate series impedance. The device maintains parameter integrity after such events if junction temperature remains within limits.
