Product details
Overview
SMBG5384AE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 160 V, ±10% tolerance (A suffix), and maximum Zener current IZM of 8.0 mA at TL < 25 °C. It uses DO-215AA gull-wing package, supports visible solder joints, and operates across –65 °C to +150 °C junction temperature range. It serves as a precision voltage reference or overvoltage clamp in industrial power supply feedback loops.
For engineers reviewing the SMBG5384AE3/TR13 datasheet, SMBG5384AE3/TR13 pinout, SMBG5384AE3/TR13 application, or SMBG5384AE3/TR13 equivalent, this page delivers verified electrical parameters, thermal derating behavior, RoHS-compliant plating details, JEDEC 1N5384B equivalence confirmation, and real-world surge current capability (IZSM = 1650 A).
Technical Context
This device functions as a silicon planar Zener diode operating in reverse breakdown, delivering stable regulation at 160 V with dynamic impedance ZZT = 350 Ω measured at IZT = 8.0 mA. Its thermal resistance junction-to-lead is 25 °C/W, enabling reliable power dissipation when mounted on FR4 with recommended footprint.
The SMBG5384AE3/TR13 exhibits low reverse leakage (IR ≤ 0.5 µA at VR = 122 V), minimal voltage drift versus current, and withstands non-repetitive 8.3 ms half-sine surge currents up to 1650 A - critical for transient suppression in DC bus protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 160 V ±10% at IZT = 8.0 mA - defines precise clamping threshold for overvoltage protection |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management below 25 °C lead temperature for full rating |
| Dynamic Impedance (ZZT) | 350 Ω at IZT = 8.0 mA - determines regulation stiffness under varying load current |
| Max Reverse Leakage (IR) | ≤ 0.5 µA at VR = 122 V - ensures minimal standby power loss in high-impedance bias networks |
| Surge Current (IZSM) | 1650 A (8.3 ms half-sine) - enables single-event transient suppression without failure |
| Junction Temp Range | –65 °C to +150 °C - supports operation in extended-temperature industrial and automotive environments |
| Thermal Resistance RθJL | 25 °C/W - quantifies thermal path efficiency from junction to lead for heatsink design |
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) | Breakdown terminal | Connected to regulated node; must be held positive relative to anode during operation |
| Anode | Reference terminal | Connected to ground or lower-potential rail; completes reverse-bias path for Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5384B equivalence | Identical electrical characteristics and test methods - enables drop-in replacement in legacy designs |
| RoHS-compliant matte-tin plating | e3 suffix confirms lead-free finish compliant with IPC/JEDEC J-STD-020B Level 1 moisture sensitivity |
| Gull-wing lead form | Enables visual solder joint inspection and reduces tombstoning risk on fine-pitch PCBs |
| High surge current rating | 1650 A peak (8.3 ms) supports robust protection against lightning-induced transients |
| Stable voltage vs. current | Low dynamic impedance (350 Ω) and minimal VZ drift ensure consistent regulation across operating range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5384B | Same VZ, IZT, ZZT, and IZSM specs; axial T-18 package instead of DO-215AA surface mount | Requires through-hole PCB layout and wave soldering; unsuitable for high-density SMT assemblies | Select when legacy through-hole manufacturing or manual prototyping is required |
| SMBJ5384B | Identical electrical specs but DO-214AA J-bend package; RθJA = 90 °C/W same, but RθJL not specified | Lacks gull-wing visibility; slightly different thermal profile due to leadframe geometry | Choose for compatibility with existing DO-214AA footprints where gull-wing inspection is not mandatory |
Compared with SMBG5384AE3/TR13, 1N5384B offers identical regulation performance but mandates through-hole assembly, while SMBJ5384B retains SMT compatibility at the cost of reduced visual solder verification - both require layout changes and do not share pinout or mechanical fit.

FAQ
What is the Zener voltage tolerance for SMBG5384AE3/TR13?
The 'A' suffix in SMBG5384AE3/TR13 specifies a ±10% Zener voltage tolerance, meaning its breakdown voltage falls between 144 V and 176 V at IZT = 8.0 mA and TL = 25 °C. This tolerance is confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0246-1 datasheet, and applies directly to the SMBG5384AE3/TR13 variant.
Is SMBG5384AE3/TR13 RoHS compliant?
Yes, SMBG5384AE3/TR13 is RoHS compliant, as indicated by the 'e3' suffix per Microsemi's nomenclature guide. It features annealed matte-tin plating and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity - no dry pack required - making it suitable for lead-free reflow processes up to 260 °C for 10 seconds.
What is the maximum surge current rating for SMBG5384AE3/TR13?
SMBG5384AE3/TR13 has a maximum non-repetitive surge current (IZSM) of 1650 A, defined as the peak value of an 8.3 ms half-sine waveform. This rating is explicitly listed in the Electrical Characteristics table on page 3 of the datasheet and reflects its capability to absorb transient energy without failure in DC bus protection applications.
How does SMBG5384AE3/TR13 compare to 1N5384B?
SMBG5384AE3/TR13 matches 1N5384B electrically - same VZ, IZT, ZZT, IR, and IZSM - but differs mechanically: SMBG5384AE3/TR13 uses DO-215AA gull-wing SMT packaging, whereas 1N5384B uses axial T-18 leads. The SMBG version enables automated assembly and visual solder inspection, unlike the through-hole 1N5384B.
What thermal derating applies to SMBG5384AE3/TR13?
SMBG5384AE3/TR13 delivers full 5.0 W power dissipation only when lead temperature (TL) remains below 25 °C. Above that, power must be linearly derated at 55.6 mW/°C - e.g., at TL = 75 °C, max PD drops to 2.22 W. This derating curve is shown in Figure 1 of the datasheet and assumes mounting on FR4 with the recommended pad layout.
