Product details
Overview
SMBG5388AE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 200 V, ±10% tolerance (A suffix), RoHS-compliant matte-tin plating (e3), and DO-215AA gull-wing package. It regulates voltage across wide current and temperature ranges, supports surge currents up to 1850 A (8.3 ms half-sine), and operates from –65 °C to +150 °C junction temperature - used in overvoltage protection circuits for industrial power supplies.
For engineers reviewing the SMBG5388AE3/TR13 datasheet, SMBG5388AE3/TR13 pinout, SMBG5388AE3/TR13 application, or SMBG5388AE3/TR13 equivalent, key selection criteria include verified 200 V Zener voltage at 5 mA test current, 480 Ω dynamic impedance at IZT, 23.6 mA maximum regulator current (IZM), and thermal resistance of 25 °C/W junction-to-lead - all confirmed per Microsemi T4-LDS-0246-1 Rev. 1.
Technical Context
This device functions as a precision voltage reference and overvoltage clamp in DC power rails. Its 200 V breakdown voltage is specified at 5 mA (IZT), with dynamic impedance of 480 Ω measured at 10% rms ac modulation superimposed on IZT - indicating stable regulation under moderate ripple conditions.
The DO-215AA gull-wing package enables visible solder joints and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity. Thermal resistance junction-to-lead is 25 °C/W, enabling 5 W dissipation only when lead temperature (TL) is maintained below 25 °C - requiring direct thermal path to PCB copper or heatsink.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 200 V ±10% at 5 mA test current - defines clamping threshold in overvoltage protection circuits. |
| Power Dissipation (PD) | 5.0 W at lead temperature < 25 °C - requires thermal management via PCB copper pour or heatsink attachment. |
| Dynamic Impedance (ZZT) | 480 Ω at 5 mA - quantifies voltage variation under small-signal AC load changes near regulation point. |
| Max Regulator Current (IZM) | 23.6 mA - maximum continuous DC current before exceeding 5 W rating at VZ = 210 V (upper tolerance limit). |
| Surge Current (IZSM) | 1850 A (8.3 ms half-sine) - supports transient suppression of lightning-induced surges in AC/DC front-ends. |
| Junction Temperature Range | –65 °C to +150 °C - validated for operation in extended-temperature industrial and outdoor equipment. |
| Reverse Leakage (IR) | 0.5 µA at 144 V - ensures minimal standby power loss in high-impedance bias networks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5388B | Axial-leaded T-18 package; identical electrical specs but no RoHS compliance (non-e3); higher RθJA (120 °C/W vs. 90 °C/W). | Requires through-hole assembly; unsuitable for high-density SMT layouts; limited surge reliability due to leadframe thermal mass. | Select when legacy through-hole design must be maintained and RoHS is not required. |
| SMBJ5388B | DO-214AA J-bend package; same Zener voltage/tolerance but lower IZSM (1500 A vs. 1850 A); identical RoHS e3 option available. | Less robust against multi-pulse surges; smaller pad area reduces thermal dissipation margin in high-power derating scenarios. | Select when board space constraints favor J-bend footprint and surge requirement is ≤1500 A. |
Compared with 1N5388B and SMBJ5388B, SMBG5388AE3/TR13 offers superior surge handling (1850 A), gull-wing visibility for AOI inspection, and guaranteed RoHS compliance - making it optimal for new SMT designs requiring field reliability and audit traceability.

FAQ
What is the Zener voltage tolerance of SMBG5388AE3/TR13?
The 'A' suffix in SMBG5388AE3/TR13 denotes ±10% Zener voltage tolerance, meaning its breakdown voltage is guaranteed between 180 V and 220 V at 5 mA test current and 25 °C. This tolerance is verified per Microsemi T4-LDS-0246-1 Rev. 1 and applies across the full operating temperature range of –65 °C to +150 °C junction temperature.
Does SMBG5388AE3/TR13 require dry packing before reflow soldering?
No, SMBG5388AE3/TR13 has IPC/JEDEC J-STD-020B Level 1 moisture sensitivity - the lowest classification - so it does not require dry packing or baking prior to reflow. The DO-215AA package uses void-free epoxy meeting UL94V-0 and is rated for standard SMT reflow profiles up to 260 °C for 10 seconds.
What is the maximum continuous current SMBG5388AE3/TR13 can handle?
SMBG5388AE3/TR13 supports a maximum continuous regulator current (IZM) of 23.6 mA when operated at its upper-tolerance Zener voltage (210 V) and lead temperature below 25 °C. At higher ambient temperatures or without thermal relief, derating per Figure 1 in the datasheet applies - e.g., ~3.7 mA at 100 °C ambient on FR4.
How does SMBG5388AE3/TR13 compare to 1N5388B in terms of surge capability?
SMBG5388AE3/TR13 and 1N5388B share identical electrical specifications including 1850 A surge current rating (8.3 ms half-sine), as both are JEDEC-registered equivalents. However, SMBG5388AE3/TR13's DO-215AA gull-wing package provides better thermal coupling to PCB copper than the axial T-18 leads of 1N5388B, improving sustained surge energy absorption in repeated-event scenarios.
Is SMBG5388AE3/TR13 compatible with lead-free reflow processes?
Yes, SMBG5388AE3/TR13 features RoHS-compliant matte-tin plating (e3 suffix) qualified per MIL-STD-750 Method 2026 and rated for solder temperatures up to 260 °C for 10 seconds - fully compatible with industry-standard lead-free reflow profiles (e.g., JEDEC J-STD-020D). The package withstands multiple reflow cycles without degradation.
