Product details
Overview
SMBG5384CE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 160 V, ±2% tolerance (C suffix), and maximum Zener current IZM of 8.0 mA at TL < 25 °C. It uses DO-215AA gull-wing package, delivers dynamic impedance ZZT of 350 Ω at IZT = 8.0 mA, and is rated for junction temperature range −65 to +150 °C. It serves as precision voltage reference and overvoltage clamp in industrial power supply feedback loops.
For engineers reviewing the SMBG5384CE3/TR13 datasheet, SMBG5384CE3/TR13 pinout, SMBG5384CE3/TR13 application, or SMBG5384CE3/TR13 equivalent, key selection criteria include verified 160 V Zener voltage at 8.0 mA test current, ±2% tolerance, 5 W power rating with thermal resistance RθJL = 25 °C/W, RoHS-compliant matte-tin plating, and DO-215AA gull-wing mechanical compatibility.
Technical Context
This device operates in reverse-biased breakdown mode, maintaining stable 160 V regulation across IZ = 1–8 mA with minimal voltage drift versus current. Its dynamic impedance of 350 Ω at 8.0 mA ensures low AC ripple coupling in feedback networks.
The DO-215AA gull-wing package enables visible solder joints and supports reflow-compatible assembly per JEDEC J-STD-020B Level 1 moisture sensitivity-no dry pack required. Thermal resistance of 25 °C/W (junction-to-lead) allows reliable 5 W dissipation with adequate PCB copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 160 V at IZT = 8.0 mA - precise reference point for closed-loop voltage regulation |
| Test Current (IZT) | 8.0 mA - operating point where VZ and ZZT are specified; defines minimum bias for stable regulation |
| Dynamic Impedance (ZZT) | 350 Ω - low AC impedance ensures minimal output voltage variation under ripple or transient load |
| Max Regulator Current (IZM) | 8.0 mA - maximum DC current at TL < 25 °C before exceeding 5 W power limit |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management via lead conduction; derates to 1.38 W at TA = 25 °C on FR4 |
| Junction Temp Range | −65 to +150 °C - supports operation in extended industrial environments without derating |
| Reverse Leakage (IR) | 0.5 µA at VR = 122 V - negligible error contribution in high-impedance sensing paths |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; banded end must be biased positive relative to anode for Zener operation. Leads are RoHS-compliant annealed matte-tin plated, solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or lower-potential rail; forms return path for Zener current |
| Cathode | Regulated output node | Banded terminal; connected to feedback node or clamping point; holds voltage at 160 V ±2% |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5384B equivalence | Identical electrical characteristics and testing to through-hole 1N5384B - enables drop-in replacement in legacy designs |
| ±2% voltage tolerance (C suffix) | Enables tighter regulation accuracy than ±5% (B) or ±10% (A) variants - critical for precision feedback |
| RoHS-compliant matte-tin plating (e3) | Meets environmental compliance without sacrificing solderability or long-term intermetallic stability |
| Level 1 moisture sensitivity | No dry pack or baking required prior to reflow - reduces manufacturing overhead and handling risk |
| Gull-wing lead form (DO-215AA) | Provides visual solder joint inspection and robust mechanical attachment on FR4 PCBs |
Applications
| Industrial Switch-Mode Power Supply Feedback | Overvoltage Protection Clamp |
|---|---|
Use Scenario: Regulates output voltage in isolated flyback converters using optocoupler-coupled feedback loop. IC Role / Device Role / Timing Role: Zener reference diode providing stable 160 V threshold for TL431 or similar shunt regulator IC biasing. Use Value: Maintains ±2% output regulation across line/load/temperature with minimal drift due to 350 Ω dynamic impedance and −65 to +150 °C operating range. |

IC Role / Device Role / Timing Role: Precision 160 V reference enabling accurate scaling of high-voltage bus monitoring signals. Use Value: ±2% tolerance ensures consistent gain calibration across production units; low IR (0.5 µA) avoids loading error in high-Z dividers. |
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 IZM specs; non-RoHS tin-lead plating | Requires axial-leaded PCB footprint and wave soldering; not suitable for high-density SMT layouts | Select when legacy through-hole assembly or cost-sensitive non-RoHS production is required |
| SMBG5384BE3/TR13 | Same DO-215AA package and 160 V rating but ±5% tolerance (B suffix); ZZT = 330 Ω at IZT = 8.0 mA | Lower accuracy acceptable in non-critical clamping; slightly lower dynamic impedance improves ripple rejection marginally | Select when ±5% tolerance suffices and lower ZZT is prioritized over tight voltage spec |
Compared with SMBG5384CE3/TR13, the 1N5384B offers identical regulation performance but demands different assembly processes, while SMBG5384BE3/TR13 trades voltage accuracy for marginally better AC impedance-making the C-suffix version optimal for precision feedback where ±2% stability is mandatory.

FAQ
What is the Zener voltage tolerance of SMBG5384CE3/TR13?
The SMBG5384CE3/TR13 has a ±2% Zener voltage tolerance, confirmed by the "C" suffix in its part number per Microsemi's nomenclature. This means its measured VZ at IZT = 8.0 mA falls between 156.8 V and 163.2 V at TL = 25 °C. The tolerance is tighter than the ±5% (B) and ±10% (A) variants, making SMBG5384CE3/TR13 suitable for applications demanding higher regulation accuracy.
Does SMBG5384CE3/TR13 require dry packing before reflow soldering?
No, SMBG5384CE3/TR13 does not require dry packing. It carries IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it can be stored indefinitely at ≤30 °C/60% RH without baking. This eliminates pre-reflow drying steps and reduces manufacturing complexity-confirmed in the "Mechanical and Packaging" section of the T4-LDS-0246-1 datasheet.
What is the maximum surge current rating for SMBG5384CE3/TR13?
The SMBG5384CE3/TR13 has a maximum non-repetitive Zener surge current (IZSM) of 1650 A for an 8.3 ms half-sine waveform, as specified in the Electrical Characteristics table on page 3 of the datasheet. This rating reflects its capability to absorb transient energy without parametric shift or failure, supporting robust overvoltage protection in industrial power stages.
How does the thermal resistance of SMBG5384CE3/TR13 affect its power handling?
SMBG5384CE3/TR13 has RθJL = 25 °C/W (junction-to-lead), enabling full 5.0 W dissipation only when leads are thermally anchored to large copper areas. On standard FR4 with recommended pad layout, its usable power drops to 1.38 W at TA = 25 °C due to higher RθJA = 90 °C/W. Engineers must design PCB copper pour accordingly to avoid thermal runaway in continuous operation.
Is SMBG5384CE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5384CE3/TR13 is qualified for lead-free reflow with a maximum solder temperature of 260 °C for 10 seconds, as stated in the Maximum Ratings table. Its RoHS-compliant matte-tin plating (e3 suffix) ensures reliable wetting and intermetallic formation under standard JEDEC J-STD-020 profiles, including peak temperatures up to 260 °C.
