Product details
Overview
SMBG5384BE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 160 V, ±5% tolerance (B suffix), 8.0 mA test current (IZT), and 350 Ω maximum dynamic impedance (ZZT) at IZT - used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5384BE3/TR13 datasheet, SMBG5384BE3/TR13 pinout, SMBG5384BE3/TR13 application, or SMBG5384BE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current rating (1650 A), thermal resistance (90 °C/W on FR4), and RoHS-compliant matte-tin plating for lead-free assembly.
Technical Context
This device operates in reverse-bias breakdown mode to maintain stable voltage across wide current ranges (IZK = 1.0 mA to IZM = 8.0 mA). Its DO-215AA gull-wing package enables visible solder joints and supports high-density PCB layouts while meeting IPC/JEDEC J-STD-020B Level 1 moisture sensitivity without dry pack.
Designed for unidirectional voltage clamping, SMBG5384BE3/TR13 exhibits minimal voltage drift over temperature (−65 °C to +150 °C junction range) and withstands non-repetitive 8.3 ms half-sine surges up to 1650 A - critical for transient suppression in industrial DC bus lines and telecom power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 160 V ±5% at 8.0 mA - defines regulated output voltage under nominal bias conditions |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management below 25 °C lead temperature or derating per Figure 1 |
| Dynamic Impedance (ZZT) | 350 Ω max at 8.0 mA - determines regulation stiffness and output ripple rejection |
| Surge Current (IZSM) | 1650 A peak (8.3 ms half-sine) - enables single-event transient suppression without failure |
| Reverse Leakage (IR) | 0.5 µA max at 122 V - ensures low standby power loss in high-impedance bias networks |
| Junction Temp Range | −65 °C to +150 °C - supports operation in automotive under-hood and industrial motor drive environments |
| Thermal Resistance RθJA | 90 °C/W on FR4 (1 oz Cu) - dictates minimum copper area needed for safe continuous operation |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; anode and cathode terminals only - polarity-critical for reverse-bias operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Positive terminal in reverse-bias configuration | Connected to regulated node; must be held at higher potential than anode during Zener operation |
| Anode | Negative terminal in reverse-bias configuration | Typically tied to system ground or return path; completes current loop during regulation |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5384B equivalence | Identical electrical specs and test methods - enables drop-in replacement in legacy designs |
| RoHS-compliant matte-tin plating | Meets lead-free reflow requirements (260 °C, 10 s) without Sn/Pb eutectic limitations |
| Level 1 moisture sensitivity | No dry pack or baking required before assembly - reduces manufacturing overhead |
| Gull-wing lead form | Enables optical inspection of solder fillets - improves process yield in automated SMT lines |
| High surge current capability | 1650 A non-repetitive rating - protects downstream circuitry from lightning-induced transients |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5384BRLG | Same 160 V ±5%, but axial T-18 package; RθJA ≈ 120 °C/W; no RoHS compliance (Sn/Pb) | Requires through-hole assembly; unsuitable for high-density SMT boards | Select when legacy through-hole production or cost-sensitive non-RoHS programs dominate |
| SMBJ5384B | Same electrical specs, but DO-214AA J-bend package; identical RoHS status and surge rating | Different footprint and solder joint geometry - requires PCB redesign | Choose if existing DO-214AA layout exists or preferred for mechanical robustness in vibration-prone systems |
Compared with SMBG5384BE3/TR13, 1N5384BRLG offers identical regulation but lacks surface-mount compatibility and RoHS compliance, while SMBJ5384B matches all electrical and environmental specs but demands different pad layout and reflow profile validation.

FAQ
What is the Zener voltage tolerance for SMBG5384BE3/TR13?
The SMBG5384BE3/TR13 has a ±5% Zener voltage tolerance, indicated by the "B" suffix in its part number. This means its measured VZ at 8.0 mA test current falls between 152 V and 168 V at TL = 25 °C. The tolerance is verified per JEDEC test methods and applies across the full operating temperature range of −65 °C to +150 °C.
Does SMBG5384BE3/TR13 require dry packing before SMT assembly?
No, SMBG5384BE3/TR13 does not require dry packing. It carries IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it can be stored indefinitely at ambient conditions (<30 °C / 60% RH) without baking. This eliminates pre-reflow drying steps and simplifies manufacturing logistics for high-volume SMT lines.
What is the maximum surge current rating for SMBG5384BE3/TR13?
The SMBG5384BE3/TR13 is rated for 1650 A peak non-repetitive surge current (IZSM) under an 8.3 ms half-sine waveform. This value is specified in the Electrical Characteristics table on page 3 of the Microsemi datasheet T4-LDS-0246-1 and reflects its capability to absorb transient energy without parametric shift or catastrophic failure.
How does the DO-215AA package of SMBG5384BE3/TR13 differ from DO-214AA?
The DO-215AA package of SMBG5384BE3/TR13 uses gull-wing leads for visible solder joint inspection, whereas DO-214AA (used in SMBJ5384B) employs J-bend leads. Both are surface-mount, but DO-215AA allows optical verification of solder fillets and has slightly lower RθJA (90 °C/W vs. ~100 °C/W for DO-214AA on identical FR4 layout).
Is SMBG5384BE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5384BE3/TR13 features RoHS-compliant annealed matte-tin plating and is qualified for lead-free reflow up to 260 °C for 10 seconds, per MIL-STD-750 method 2026. Its plastic body meets UL94V-0 flammability rating, and the "e3" suffix explicitly confirms RoHS compliance per EU Directive 2011/65/EU.
