Product details
Overview
SMBG5388CE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 200 V, ±2% tolerance (C suffix), RoHS-compliant matte-tin plating (e3), and DO-215AA gull-wing package. It regulates voltage across wide current and temperature ranges and withstands high surge stresses in power supply protection circuits.
For engineers reviewing the SMBG5388CE3/TR13 datasheet, SMBG5388CE3/TR13 pinout, SMBG5388CE3/TR13 application, or SMBG5388CE3/TR13 equivalent, key selection criteria include Zener voltage accuracy (±2%), maximum surge current (1850 A), thermal resistance (90 °C/W on FR4), and moisture sensitivity level (MSL 1, no dry pack required).
Technical Context
This device operates as a precision voltage reference and overvoltage clamp in DC power rails. Its 200 V Zener voltage is specified at 5.0 mA test current (IZT), with dynamic impedance of 480 Ω at that point and knee impedance of 23.6 Ω at 1.0 mA (ZZK).
The SMBG5388CE3/TR13 features low leakage (IR ≤ 0.5 µA at VR = 144 V), stable regulation under surge conditions (non-repetitive 8.3 ms half-sine IZSM = 1850 A), and thermal derating to 1.38 W at TA = 25 °C when mounted on standard FR4 with recommended footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 200 V ±2% at IZT = 5.0 mA - precise clamping threshold for 200 V rail protection |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management for sustained operation |
| Max Surge Current (IZSM) | 1850 A (8.3 ms half-sine) - handles transient overvoltage events per IEC 61000-4-5 |
| Dynamic Impedance (ZZT) | 480 Ω at IZT = 5.0 mA - determines voltage regulation stability under load variation |
| Reverse Leakage (IR) | ≤0.5 µA at VR = 144 V - ensures minimal standby power loss in high-impedance bias networks |
| Thermal Resistance (RθJA) | 90 °C/W on FR4 (1 oz Cu) - defines temperature rise per watt dissipated in typical PCB layout |
| Moisture Sensitivity Level | MSL 1 - zero floor life limitation; no baking or dry pack required before reflow |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; banded end must be held positive relative to anode during regulation. Terminals are solderable per MIL-STD-750, method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-bias operation | Connected to lower-potential side of protected circuit; forms return path for Zener current |
| Cathode (banded end) | Regulated output node | Connected to higher-potential rail; maintains 200 V ±2% above anode under regulation |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5388B equivalence | Identical electrical specs and test methods - enables drop-in replacement in legacy designs |
| Gull-wing lead form | Visible solder joints for automated optical inspection (AOI) and reliable reflow yield |
| RoHS-compliant matte-tin plating (e3) | Lead-free assembly compatibility without sacrificing solderability or corrosion resistance |
| High surge current rating | 1850 A peak allows single-device transient suppression in industrial 200 V DC systems |
| MSL 1 moisture classification | Eliminates pre-bake steps and dry storage logistics - reduces manufacturing overhead |
Applications
| Industrial DC Power Supply Protection | Telecom Rectifier Output Clamping |
|---|---|
Use Scenario: Protecting 200 V DC bus in programmable logic controller (PLC) power modules against load dump transients. IC Role / Device Role / Timing Role: Voltage clamp placed across bus to shunt excess energy into ground when input exceeds 200 V.

IC Role / Device Role / Timing Role: Zener reference in feedback loop of isolated flyback regulator controlling rectifier output. Use Value: Maintains ±2% output accuracy over temperature (-40 to +125 °C) due to low dynamic impedance (480 Ω) and stable VZ drift. |
| Automotive Battery Management System (BMS) | Test Equipment High-Voltage Reference |

Use Value: Delivers 200 V ±2% at 5 mA with 480 Ω dynamic impedance - supports <0.1% measurement uncertainty in metrology-grade instruments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5388BRLG | Same 200 V ±2%, but axial T-18 package; RθJA ≈ 50 °C/W (lower thermal resistance), no MSL rating | Requires through-hole mounting and board space; unsuitable for high-density SMT lines | Select only if legacy through-hole assembly or superior thermal performance without PCB area constraints is prioritized. |
| SMBJ5388B | Same 200 V ±2%, but DO-214AA J-bend package; RθJA = 90 °C/W same, but different pad layout and solder joint geometry | Compatible with same PCB footprint only if redesigned; gull-wing offers better AOI visibility than J-bend | Choose when existing DO-214AA tooling exists and visual solder inspection is less critical than cost. |
Compared with SMBG5388CE3/TR13, 1N5388BRLG provides better thermal performance but sacrifices SMT compatibility, while SMBJ5388B matches SMT requirements but lacks gull-wing solder joint visibility-making SMBG5388CE3/TR13 optimal for automated high-reliability production of 200 V regulated supplies.

FAQ
What is the Zener voltage tolerance of SMBG5388CE3/TR13?
The SMBG5388CE3/TR13 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its breakdown voltage is guaranteed between 196 V and 204 V when measured at 5.0 mA test current (IZT) and 25 °C junction temperature. The tolerance is verified per JEDEC test methods and applies across the full operating temperature range of –65 °C to +150 °C.
Does SMBG5388CE3/TR13 require dry packing before reflow soldering?
No, SMBG5388CE3/TR13 does not require dry packing before reflow soldering. It carries IPC/JEDEC J-STD-020B Moisture Sensitivity Level (MSL) 1 certification, meaning it has unlimited floor life and can be stored and processed directly without baking or humidity-controlled packaging. This simplifies manufacturing logistics and eliminates pre-reflow bake cycles.
What is the maximum surge current rating for SMBG5388CE3/TR13?
The SMBG5388CE3/TR13 is rated for a non-repetitive peak surge current (IZSM) of 1850 A, defined as an 8.3 ms half-sine waveform. This rating is validated per industry-standard surge testing protocols and reflects the device's ability to absorb transient energy without failure-critical for protecting 200 V DC systems against lightning-induced or switching-induced overvoltages.
How does the DO-215AA package of SMBG5388CE3/TR13 differ from DO-214AA?
The DO-215AA package used by SMBG5388CE3/TR13 features gull-wing leads, enabling visible solder joints for automated optical inspection (AOI), whereas DO-214AA uses J-bend leads with hidden solder fillets. Both share identical thermal resistance (90 °C/W on FR4), but DO-215AA's lead geometry improves process control in high-reliability SMT lines where solder joint integrity verification is mandatory.
Is SMBG5388CE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5388CE3/TR13 is fully compatible with lead-free reflow profiles. Its RoHS-compliant matte-tin plating (denoted by "e3") supports peak reflow temperatures up to 260 °C for 10 seconds, meeting JEDEC J-STD-020 requirements. The device's plastic encapsulation is UL94V-0 rated and thermally stable under standard Pb-free thermal cycling conditions.
