Product details
Overview
SMBG5383AE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with 150 V nominal breakdown voltage (VZ), ±10% tolerance (suffix A), RoHS-compliant matte-tin plating, and DO-215AA gull-wing package. It regulates voltage in power supply feedback loops, overvoltage protection circuits, and reference voltage generation across industrial and telecom power systems.
For engineers reviewing the SMBG5383AE3/TR13 datasheet, SMBG5383AE3/TR13 pinout, SMBG5383AE3/TR13 application, or SMBG5383AE3/TR13 equivalent, key selection criteria include its 150 V Zener voltage at 8.0 mA test current, 330 Ω dynamic impedance, 0.5 µA reverse leakage at 108 V, and 1.1 A non-repetitive surge rating - all validated under JEDEC-compliant test conditions.
Technical Context
This device operates as a precision voltage reference in reverse-biased mode, with cathode band marking polarity and stable regulation across -65°C to +150°C junction temperature range. Its 25°C/W junction-to-lead thermal resistance enables reliable 5 W dissipation when mounted on FR4 with recommended footprint.
The SMBG5383AE3/TR13 exhibits minimal voltage drift versus current due to low dynamic impedance (330 Ω at IZT = 8.0 mA) and maintains tight regulation under transient surges up to 1.1 A (8.3 ms half-sine), meeting MIL-STD-750 ESD robustness requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 150 V ±10% at IZT = 8.0 mA - defines precise clamping threshold for overvoltage protection circuits |
| Power Dissipation (PD) | 5.0 W at TL < 25°C - supports continuous regulation in compact power supplies with adequate heat sinking |
| Dynamic Impedance (ZZT) | 330 Ω at IZT = 8.0 mA - ensures low output voltage variation under load current changes |
| Reverse Leakage (IR) | 0.5 µA max at VR = 108 V - guarantees minimal standby power loss in high-impedance bias networks |
| Surge Current (IZSM) | 1.1 A peak (8.3 ms half-sine) - withstands lightning-induced transients without degradation |
| Junction Temperature Range | -65°C to +150°C - enables operation in automotive under-hood and industrial motor drive environments |
| Thermal Resistance (RθJL) | 25°C/W - allows direct thermal path to PCB copper for efficient heat transfer in high-density layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5383B | Through-hole DO-41 package; identical VZ, IZT, ZZT, and IR specs but higher RθJA (150°C/W) | Requires axial-leaded PCB layout; unsuitable for high-density SMT assemblies | Select when legacy through-hole compatibility or manual prototyping is prioritized over board space savings |
| SMBG5383BE3/TR13 | Same DO-215AA package and 150 V rating but ±5% tolerance (suffix B); lower ZZT = 300 Ω at 8.0 mA | Better regulation accuracy needed for precision references; tighter tolerance increases cost | Choose when system-level voltage tolerance budget demands <±7.5% deviation at operating current |
Compared with SMBG5383AE3/TR13, 1N5383B requires PCB redesign for through-hole mounting and offers inferior thermal performance, while SMBG5383BE3/TR13 delivers tighter regulation at higher cost - making SMBG5383AE3/TR13 optimal for cost-sensitive industrial power clamping where ±10% VZ is acceptable.

FAQ
What is the Zener voltage tolerance of SMBG5383AE3/TR13?
The SMBG5383AE3/TR13 has a ±10% Zener voltage tolerance, indicated by the 'A' suffix in its part number. This means its breakdown voltage is guaranteed between 135 V and 165 V when measured at 8.0 mA test current and 25°C ambient. The tolerance directly impacts regulation accuracy in feedback circuits and must be accounted for in system-level voltage margin analysis for SMBG5383AE3/TR13.
Does SMBG5383AE3/TR13 require moisture preconditioning before reflow?
No, SMBG5383AE3/TR13 has a Moisture Sensitivity Level (MSL) 1 rating per IPC/JEDEC J-STD-020B, meaning it can be stored indefinitely at ≤30°C/60% RH without dry packing or baking. This eliminates pre-reflow baking steps and reduces manufacturing risk - a key advantage confirmed in Microsemi's T4-LDS-0246-1 datasheet for SMBG5383AE3/TR13.
What is the maximum surge current rating for SMBG5383AE3/TR13?
The SMBG5383AE3/TR13 is rated for 1.1 A peak non-repetitive surge current (IZSM) under an 8.3 ms half-sine waveform, as specified in the Electrical Characteristics table on page 3 of the Microsemi datasheet. This value is critical for sizing SMBG5383AE3/TR13 in transient voltage suppression applications where IEC 61000-4-5 compliance is required.
How does the thermal resistance of SMBG5383AE3/TR13 affect its power handling?
SMBG5383AE3/TR13 has a junction-to-lead thermal resistance (RθJL) of 25°C/W, enabling full 5.0 W dissipation only when the lead temperature (TL) is maintained below 25°C - typically achieved via copper pour or thermal vias. At 25°C ambient, derated power drops to 1.38 W due to higher RθJA (90°C/W), so SMBG5383AE3/TR13 thermal design must prioritize lead-to-PCB conduction.
Is SMBG5383AE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5383AE3/TR13 features RoHS-compliant matte-tin plating (e3 suffix) and is qualified for solder reflow at 260°C for 10 seconds, meeting standard lead-free JEDEC J-STD-020 requirements. Its plastic encapsulation is void-free thermosetting epoxy rated UL94V-0, ensuring reliability under repeated thermal cycling - a verified specification for SMBG5383AE3/TR13.
