Product details
Overview
SMBG5384A/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 160 V, ±10% tolerance (A-suffix), and maximum regulator current of 8.0 mA at 25 °C. It uses DO-215AA gull-wing packaging, 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 SMBG5384A/TR13 datasheet, SMBG5384A/TR13 pinout, SMBG5384A/TR13 application, or SMBG5384A/TR13 equivalent, this page delivers verified electrical specs, thermal derating behavior, RoHS-compliant plating status, and direct JEDEC 1N5384A compatibility - all critical for high-reliability DC regulation and surge protection design.
Technical Context
This device functions as a silicon planar Zener diode operating in reverse-biased breakdown mode, delivering stable voltage regulation under controlled current conditions. Its dynamic impedance is 350 Ω at 8.0 mA test current, and it exhibits low leakage (<0.5 µA) at 114 V reverse voltage.
The SMBG5384A/TR13 is thermally rated for 5.0 W dissipation at lead temperature <25 °C, with RθJL = 25 °C/W and RθJA = 90 °C/W on FR4 board. Its moisture sensitivity level is IPC/JEDEC Level 1 - no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 160 V ±10% - defines clamping threshold in overvoltage protection circuits |
| Test Current (IZT) | 8.0 mA - standard bias point for VZ measurement and impedance characterization |
| Dynamic Impedance (ZZT) | 350 Ω - indicates voltage stability under small-signal AC modulation at IZT |
| Max Regulator Current (IZM) | 8.0 mA - maximum continuous DC current before exceeding 5 W rating at TL ≤25 °C |
| Reverse Leakage (IR) | <0.5 µA @ 114 V - ensures minimal standby power loss in high-impedance bias networks |
| Surge Current (IZSM) | 1650 A (8.3 ms half-sine) - supports transient overvoltage suppression without failure |
| Junction Temp Range | –65 °C to +150 °C - enables operation in extended-temperature industrial and automotive environments |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; terminals are anode and cathode only. Cathode is banded end; device must be operated with banded end positive relative to anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Breakdown terminal | Connected to regulated node or voltage reference point; polarity must be observed to enable Zener conduction |
| Anode | Reference terminal | Typically tied to ground or lower-potential rail; completes reverse-bias path for regulation |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5384A equivalence | Identical electrical characteristics and test methods - enables drop-in replacement in legacy designs |
| Gull-wing leads (DO-215AA) | Enables visual solder joint inspection and reliable reflow attachment on high-density PCBs |
| Moisture Sensitivity Level 1 | No dry pack or baking required prior to assembly - reduces manufacturing overhead |
| RoHS-compliant matte-tin plating | Meets EU Directive 2011/65/EU and supports lead-free reflow profiles up to 260 °C |
| High surge current rating | 1650 A non-repetitive peak withstand capability - protects downstream circuitry from line transients |

Use Value: 350 Ω dynamic impedance ensures minimal loading effect on divider output under varying current conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5384A | Through-hole axial T-18 package; identical VZ, IZT, and ZZT; same ±10% tolerance | Requires through-hole assembly and larger board area; not suitable for automated SMT lines | Select when legacy through-hole design or manual prototyping is required |
| SMBJ5384A | Same Zener specs but in DO-214AA (J-bend) package; slightly higher RθJA (100 °C/W vs. 90 °C/W) | Compatible footprint for J-bend mount; less visible solder joint inspection than gull-wing | Select when existing layout uses SMBJ-style pads or tighter height constraints apply |
Compared with SMBG5384A/TR13, 1N5384A offers identical regulation performance but requires through-hole assembly, while SMBJ5384A provides SMT compatibility with marginally reduced thermal efficiency - both serve as functionally aligned alternatives where package form factor differs.

FAQ
What is the Zener voltage tolerance for SMBG5384A/TR13?
The "A" suffix in SMBG5384A/TR13 specifies a ±10% Zener voltage tolerance. This means the measured VZ at 8.0 mA test current falls between 144 V and 176 V at 25 °C. The tolerance directly impacts regulation accuracy in feedback or clamping applications and must be accounted for in worst-case design margins.
Is SMBG5384A/TR13 RoHS compliant?
Yes, SMBG5384A/TR13 uses RoHS-compliant annealed matte-tin plating per MIL-STD-750 method 2026. The "TR13" suffix confirms tape-and-reel packaging, and the absence of "e3" in the base part number does not affect RoHS status - Microsemi's standard SMBG53xxA production is RoHS-compliant unless otherwise specified.
What is the maximum power dissipation for SMBG5384A/TR13 at 70 °C ambient?
At 70 °C ambient on FR4 board, SMBG5384A/TR13 derates to approximately 2.8 W based on its RθJA = 90 °C/W and 5.0 W rating at TL ≤25 °C. Derating follows linear curve in Figure 1 of the datasheet: PD = 5.0 × (1 − (TA − 25)/125). Always verify thermal layout against recommended pad dimensions.
How does SMBG5384A/TR13 compare to SMBG5384B in regulation performance?
SMBG5384A/TR13 has ±10% VZ tolerance and 350 Ω dynamic impedance at 8.0 mA, whereas SMBG5384B offers ±5% tolerance and identical ZZT. The "B" variant provides tighter voltage control for precision references, while SMBG5384A/TR13 suits cost-sensitive or less-critical clamping roles where ±10% is acceptable.
Can SMBG5384A/TR13 replace 1N5384A in existing designs?
Yes - SMBG5384A/TR13 is explicitly stated as electrically equivalent to JEDEC 1N5384A with identical test conditions and characteristics. However, the DO-215AA gull-wing package requires PCB footprint revision from axial T-18; mechanical compatibility is not maintained, though functional substitution is fully supported.
