Product details
Overview
SMBG5388A/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 200 V, ±10% tolerance (A-suffix), 0.5 µA maximum reverse leakage at 144 V, and DO-215AA gull-wing package. It regulates voltage in high-voltage power supply rails and surge protection circuits where stable clamping above 150 V is required.
For engineers reviewing the SMBG5388A/TR13 datasheet, SMBG5388A/TR13 pinout, SMBG5388A/TR13 application, or SMBG5388A/TR13 equivalent, key selection criteria include Zener voltage tolerance, IZM current rating at elevated temperature, thermal resistance junction-to-lead (25 °C/W), surge current capability (1850 A), and RoHS compliance status (non-RoHS, A-suffix).
Technical Context
This device operates in reverse breakdown to maintain stable voltage across wide current ranges (5 mA to 23.6 mA typical IZM). Its dynamic impedance is 480 Ω at 5 mA test current, and it exhibits minimal voltage drift over temperature due to low TCZ (typical <0.07 %/°C for 200 V parts in this series).
The SMBG5388A/TR13 uses a void-free thermosetting epoxy case rated UL94V-0, with gull-wing leads plated in Sn/Pb (non-RoHS), cathode indicated by band. It meets MIL-STD-750 method 1020 for ESD immunity and has IPC/JEDEC J-STD-020B Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 200 V ±10% - Clamps at 180–220 V under 5 mA test current; defines upper limit of protected rail voltage. |
| Maximum Regulator Current (IZM) | 23.6 mA - Maximum continuous DC current at 25 °C lead temperature; determines sustained power dissipation (5 W). |
| Reverse Leakage (IR) | 0.5 µA max at 144 V - Ensures minimal standby power loss in high-impedance bias networks. |
| Dynamic Impedance (ZZT) | 480 Ω at 5 mA - Quantifies voltage regulation stiffness; lower values indicate tighter regulation under load transients. |
| Thermal Resistance (RθJL) | 25 °C/W - Junction-to-lead thermal path enables reliable heat transfer to PCB copper; critical for derating above 25 °C. |
| Surge Current (IZSM) | 1850 A (8.3 ms half-sine) - Withstands single-event lightning-induced surges without degradation. |
| Package | DO-215AA - Gull-wing surface-mount footprint (12 mm tape/reel, TR13 suffix); allows visual solder joint inspection. |
Pinout & Package
DO-215AA gull-wing package with two terminals: anode and cathode. Cathode identified by molded band; device operated with banded end positive relative to anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or lowest potential point; forms return path for Zener current. |
| Cathode | Regulated output node | Banded terminal; connected to voltage rail being clamped; maintains stable 200 V reference under load. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5388B equivalent | Identical electrical specs and test methods - enables drop-in replacement in legacy designs qualified to 1N5388B. |
| Level 1 moisture sensitivity | No dry pack required - eliminates baking step before reflow, reducing manufacturing cost and handling risk. |
| Gull-wing lead form | Visible solder joints - supports automated optical inspection (AOI) and improves process yield in high-density layouts. |
| Non-ESD-sensitive | MIL-STD-750 method 1020 compliant - withstands human-body-model discharges without parameter shift or failure. |
| High surge endurance | 1850 A non-repetitive peak - protects downstream circuitry from IEC 61000-4-5 level 4 surges without external TVS stacking. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5388B | Same Zener voltage (200 V), ±5% tolerance (B-suffix), identical DO-214AA package; higher test current (5 mA vs. 5 mA), lower ZZT (450 Ω). | Used in legacy through-hole or J-bend SMT designs; not gull-wing; requires different footprint. | Select when ±5% tolerance and lower dynamic impedance are prioritized over gull-wing manufacturability. |
| SMBJ5388A | Same voltage/tolerance, but DO-214AA J-bend package; RθJA = 90 °C/W (vs. 90 °C/W same), but RθJL not specified; no gull-wing visibility. | Preferred for space-constrained boards where J-bend footprint saves area; lacks visual solder inspection capability. | Select when board real estate is constrained and AOI of solder joints is not required. |
Compared with SMBG5388A/TR13, 1N5388B offers tighter voltage tolerance but requires axial-leaded assembly or DO-214AA rework, while SMBJ5388A sacrifices gull-wing inspection for smaller footprint-making SMBG5388A/TR13 optimal for high-reliability, AOI-enabled production of 200 V Zener regulation.

FAQ
What is the Zener voltage tolerance of SMBG5388A/TR13?
The SMBG5388A/TR13 has a Zener voltage tolerance of ±10%, as indicated by the "A" suffix in the part number. This means its measured VZ falls between 180 V and 220 V when tested at 5 mA and 25 °C. The tolerance directly affects regulation accuracy in precision biasing applications, and must be accounted for in worst-case design margins for the SMBG5388A/TR13.
Is SMBG5388A/TR13 RoHS compliant?
No, SMBG5388A/TR13 is not RoHS compliant. The "A" suffix denotes ±10% tolerance and Sn/Pb plating; RoHS-compliant versions use the "e3" suffix (e.g., SMBG5388Be3). The SMBG5388A/TR13 uses traditional tin-lead gull-wing terminations and requires exemption documentation for restricted-use applications.
What is the maximum surge current rating for SMBG5388A/TR13?
The SMBG5388A/TR13 is rated for a non-repetitive peak surge current (IZSM) of 1850 A, defined per an 8.3 ms half-sine waveform. This rating reflects its ability to absorb high-energy transients without parametric shift or catastrophic failure, making it suitable for primary-side surge suppression in SMBG5388A/TR13-based protection circuits.
How does the DO-215AA package of SMBG5388A/TR13 differ from DO-214AA?
The DO-215AA package of SMBG5388A/TR13 features gull-wing leads for visible solder joints and improved thermal conduction via leadframe, whereas DO-214AA (used in SMBJ5388A) uses J-bend leads. Both share identical thermal resistance to ambient (90 °C/W), but DO-215AA enables AOI and offers lower RθJL (25 °C/W) than DO-214AA variants, enhancing SMBG5388A/TR13 thermal performance in lead-attached layouts.
Can SMBG5388A/TR13 replace 1N5388B in existing designs?
Yes, SMBG5388A/TR13 is electrically equivalent to 1N5388B per Microsemi documentation, sharing identical VZ, IZT, ZZT, and IZM. However, the SMBG5388A/TR13 uses DO-215AA gull-wing packaging versus 1N5388B's axial DO-41, so PCB layout and assembly process must be updated-SMBG5388A/TR13 is not a drop-in mechanical replacement.
