Product details
Overview
SMBG5380CE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 120 V, ±2% tolerance (C suffix), and maximum regulator current of 10 mA at 25 °C. It uses DO-215AA gull-wing package, supports visible solder joints, and operates across –65 to +150 °C junction temperature range. It serves as a precision voltage reference in industrial power supply feedback loops.
For engineers reviewing the SMBG5380CE3/TR13 datasheet, SMBG5380CE3/TR13 pinout, SMBG5380CE3/TR13 application, or SMBG5380CE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (RθJL = 25 °C/W), surge current rating (1150 A), dynamic impedance (170 Ω), and RoHS-compliant matte-tin plating.
Technical Context
This device functions as a two-terminal voltage regulator diode operating in reverse-biased breakdown mode. Its Zener voltage is specified at 120 V with ±2% tolerance, tested at IZT = 10 mA, and exhibits dynamic impedance of 170 Ω at that current.
It delivers stable regulation over wide temperature (–65 to +150 °C) and current ranges, with non-repetitive surge capability up to 1150 A (8.3 ms half-sine). The DO-215AA gull-wing package provides low thermal resistance (RθJL = 25 °C/W) and IPC/JEDEC Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 120 V ±2% at IZT = 10 mA - defines precise regulation point for feedback networks |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management on PCB for sustained operation |
| Dynamic Impedance (ZZT) | 170 Ω at IZT = 10 mA - determines output voltage variation under load transients |
| Maximum Regulator Current (IZM) | 10 mA - sets upper limit for stable DC biasing without exceeding power rating |
| Surge Current (IZSM) | 1150 A (8.3 ms half-sine) - enables transient overvoltage clamping in surge protection circuits |
| Junction-to-Lead Thermal Resistance | 25 °C/W - supports efficient heat transfer to PCB copper when lead-mounted |
| Moisture Sensitivity Level | Level 1 per J-STD-020B - eliminates dry-pack requirement and simplifies handling |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; terminals are anode and cathode only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Reverse-bias terminal | Connected to higher potential in regulation circuit; polarity must be observed to avoid forward conduction |
| Anode | Reference/ground terminal | Typically tied to system ground or feedback node; completes reverse-bias path for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5380B equivalent | Identical electrical characteristics and test methods - ensures drop-in compatibility with legacy designs |
| RoHS-compliant matte-tin plating | Meets environmental compliance requirements without sacrificing solderability or reliability |
| Gull-wing lead form | Enables visual solder joint inspection and improves mechanical stability on FR4 boards |
| Level 1 moisture sensitivity | Eliminates dry-pack storage and bake-out steps - reduces manufacturing overhead |
| High surge current rating | 1150 A peak (8.3 ms) supports robust transient suppression in industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5380B | Same Zener voltage (120 V), ±5% tolerance, axial T-18 package | Requires through-hole mounting and larger board area; not suitable for high-density SMT layouts | Select when legacy through-hole assembly or higher surge margin (1200 A) is prioritized over footprint size |
| SMBJ5380B | Same Zener voltage (120 V), ±5% tolerance, DO-214AA J-bend package | Different thermal resistance (RθJA = 90 °C/W vs. 25 °C/W to lead); lower surge rating (1000 A) | Select when J-bend footprint is already standardized; verify thermal derating in high-power density designs |
Compared with SMBG5380CE3/TR13, 1N5380B offers identical regulation but lacks SMT compatibility, while SMBJ5380B shares the surface-mount form factor but trades tighter tolerance and superior thermal performance for lower cost and broader availability.

FAQ
What is the Zener voltage tolerance of SMBG5380CE3/TR13?
The SMBG5380CE3/TR13 has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in the part number. This means its breakdown voltage is guaranteed between 117.6 V and 122.4 V when measured at IZT = 10 mA and TL = 25 °C. This tighter tolerance supports high-accuracy regulation compared to ±5% (B suffix) or ±10% (A suffix) variants of the SMBG5380 series.
Does SMBG5380CE3/TR13 require dry-pack handling?
No, SMBG5380CE3/TR13 does not require dry-pack handling. It carries IPC/JEDEC J-STD-020B Moisture Sensitivity Level 1 rating, meaning it can be stored and processed indefinitely at ambient conditions without baking or humidity-controlled packaging. This simplifies manufacturing logistics and eliminates pre-reflow bake steps for SMBG5380CE3/TR13.
What is the maximum surge current rating for SMBG5380CE3/TR13?
The SMBG5380CE3/TR13 has a maximum non-repetitive surge current (IZSM) rating of 1150 A for an 8.3 ms half-sine waveform. This value is confirmed in the Electrical Characteristics table on page 3 of the Microsemi datasheet T4-LDS-0246-1. It reflects the device's ability to absorb transient energy without failure in overvoltage protection applications.
How does the DO-215AA package of SMBG5380CE3/TR13 differ from DO-214AA?
The DO-215AA package used by SMBG5380CE3/TR13 features gull-wing leads enabling visible solder joints and lower thermal resistance (RθJL = 25 °C/W), whereas DO-214AA (used in SMBJ5380B) has J-bend leads with higher RθJA = 90 °C/W. The gull-wing geometry improves solder joint inspection and mechanical reliability under thermal cycling, making SMBG5380CE3/TR13 preferable for high-reliability industrial use.
Is SMBG5380CE3/TR13 compatible with lead-free reflow processes?
Yes, SMBG5380CE3/TR13 is compatible with lead-free reflow processes. Its RoHS-compliant matte-tin plating meets MIL-STD-750 Method 2026 solderability requirements, and the device is rated for solder temperature up to 260 °C for 10 seconds. The package body is void-free thermosetting epoxy rated UL94V-0, ensuring stability during standard Pb-free reflow profiles.
