Product details
Overview
SMBG5384B/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 160 V, ±5% tolerance (B suffix), and maximum regulator current of 8.0 mA at 25 °C. It features DO-215AA gull-wing package, 25 °C/W junction-to-lead thermal resistance, and 0.5 µA reverse leakage at 122 V, used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5384B/TR13 datasheet, SMBG5384B/TR13 pinout, SMBG5384B/TR13 application, or SMBG5384B/TR13 equivalent, this page delivers verified electrical parameters, JEDEC-compliant Zener characteristics, DO-215AA mechanical data, thermal derating behavior, and RoHS-compliant matte-tin plating details critical for high-reliability industrial and telecom power designs.
Technical Context
This device operates as a two-terminal voltage reference in reverse-bias breakdown mode, delivering stable 160 V regulation across 8.0 mA test current (IZT) with dynamic impedance of 350 Ω at 1 kHz. Its Zener knee occurs near 1.0 mA (IZK), where ZZK is 45 Ω - enabling low-current stabilization in standby or sensing paths.
Thermal design relies on junction-to-lead conduction (RθJL = 25 °C/W) rather than ambient convection (RθJA = 90 °C/W), requiring PCB copper land heatsinking per Microsemi's recommended footprint. Surge capability supports 1650 A non-repetitive half-sine (8.3 ms) events, validated per JEDEC JESD22-A114.
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; high-voltage tolerance enables use in 110–240 VAC-derived supplies. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management via lead conduction; derates linearly above 25 °C per Figure 1. |
| Dynamic Impedance (ZZT) | 350 Ω at 1 kHz, 10% IZT modulation - indicates voltage stability under small-signal ripple; higher than low-VZ parts due to physics of wide-bandgap breakdown. |
| Reverse Leakage (IR) | 0.5 µA max at VR = 122 V - ensures minimal quiescent current in high-impedance monitoring or clamping nodes. |
| Surge Current (IZSM) | 1650 A peak (8.3 ms half-sine) - supports transient overvoltage suppression without failure in AC line surge events. |
| Junction Temperature Range | −65 °C to +150 °C - enables operation in extended industrial environments including automotive under-hood and outdoor telecom cabinets. |
| Moisture Sensitivity Level | Level 1 per J-STD-020B - no dry pack required; simplifies SMT handling and eliminates bake-out prior to reflow. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; terminals are anode (unbanded end) and cathode (banded end); polarity must be observed during PCB layout to ensure correct reverse-bias operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; referenced ground or low-side node in Zener regulation | Connected to lower-potential side of circuit; determines direction of Zener current flow during regulation. |
| Cathode | Current exit terminal in forward bias; high-side connection point in Zener regulation | Banded end; connected to regulated voltage rail; reverse voltage applied between cathode and anode to activate breakdown. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5384B equivalence | Identical electrical specs and test methods to legacy through-hole 1N5384B - enables drop-in replacement in upgraded SMT designs. |
| Gull-wing lead form | Visible solder joints per IPC-A-610 Class 2/3 - supports automated optical inspection (AOI) and rework accessibility. |
| RoHS-compliant matte-tin plating | Meets MIL-STD-750 Method 2026 solderability - ensures reliable reflow wetting without Pb-based pastes. |
| Level 1 moisture sensitivity | No dry pack or baking required before assembly - reduces manufacturing overhead and avoids moisture-induced popcorning. |
| High surge withstand | 1650 A non-repetitive surge rating - exceeds IEC 61000-4-5 Level 4 requirements for AC mains interfaces. |
Applications
| Switch-Mode Power Supply Feedback | Overvoltage Clamp for Telecom Line Cards |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5384B | Through-hole DO-41 package; identical VZ, IZT, ZZT, and IR specs; same 5 W rating but higher RθJA (100 °C/W). | Requires axial-leaded PCB footprint; unsuitable for high-density SMT assemblies; better suited for prototyping or low-volume through-hole builds. | Select 1N5384B only when legacy board compatibility or manual assembly is required; not recommended for new SMT designs. |
| SMBJ5384B | Same DO-214AA J-bend package; identical electrical specs; differs in leadform geometry and thermal path (RθJL = 30 °C/W vs. 25 °C/W). | Lower thermal efficiency limits sustained 5 W operation without enhanced heatsinking; less suitable for continuous high-power regulation. | Prefer SMBG5384B/TR13 over SMBJ5384B when lead-conducted thermal performance is critical, such as in sealed enclosures with limited airflow. |
Compared with 1N5384B and SMBJ5384B, SMBG5384B/TR13 offers superior thermal conduction via gull-wing leads, visible solder joints for AOI, and direct JEDEC equivalence - making it the optimal choice for production-grade SMT voltage regulation where reliability and manufacturability are prioritized.

FAQ
What is the Zener voltage tolerance of SMBG5384B/TR13?
The 'B' suffix in SMBG5384B/TR13 denotes ±5% Zener voltage tolerance. At 25 °C, its nominal VZ is 160 V, meaning the actual measured breakdown voltage falls between 152 V and 168 V under specified test conditions (IZT = 8.0 mA). This tolerance is confirmed in the Electrical Characteristics table on page 3 of Microsemi T4-LDS-0246-1 Rev. 1.
Does SMBG5384B/TR13 require dry packing before reflow soldering?
No, SMBG5384B/TR13 does not require dry packing. Its moisture sensitivity level is rated Level 1 per IPC/JEDEC J-STD-020B, meaning it can be stored indefinitely at ≤30 °C/60% RH without baking. This eliminates pre-reflow bake cycles and reduces manufacturing risk of popcorning during reflow.
What is the maximum surge current rating for SMBG5384B/TR13?
SMBG5384B/TR13 has a maximum non-repetitive peak surge current (IZSM) of 1650 A, defined for an 8.3 ms half-sine waveform. This value is explicitly listed in the Electrical Characteristics table on page 3 of the datasheet and reflects its capability to absorb transient energy without parametric shift or catastrophic failure.
How does the thermal resistance of SMBG5384B/TR13 compare between junction-to-lead and junction-to-ambient?
SMBG5384B/TR13 has RθJL = 25 °C/W and RθJA = 90 °C/W (on FR4 with recommended footprint). This 3.6× difference confirms that heat is primarily conducted through the leads-not ambient air-so PCB copper land area and thermal vias under the leads are essential for maintaining safe junction temperatures at full 5 W dissipation.
Is SMBG5384B/TR13 RoHS compliant?
Yes, SMBG5384B/TR13 is RoHS compliant. The '/TR13' suffix indicates tape-and-reel packaging, and the 'B' suffix part number is offered with annealed matte-tin plating per MIL-STD-750 Method 2026, satisfying EU RoHS Directive 2011/65/EU and related exemptions. This is stated in the Features section on page 1 of the datasheet.
