Product details
Overview
SMBG5380BE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 120 V, ±5% tolerance (B 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 1150 A (8.3 ms half-sine), and is used in overvoltage protection circuits for industrial power supplies.
For engineers reviewing the SMBG5380BE3/TR13 datasheet, SMBG5380BE3/TR13 pinout, SMBG5380BE3/TR13 application, or SMBG5380BE3/TR13 equivalent, key selection criteria include Zener voltage accuracy at IZT = 10 mA, dynamic impedance of 170 Ω at IZT, maximum regulator current of 5.5 mA, thermal resistance RθJA = 90 °C/W on FR4, and compliance with MIL-STD-750 ESD testing.
Technical Context
This device operates as a precision voltage reference and transient suppressor in DC bias networks and clamping stages. Its 120 V Zener voltage is specified at 10 mA test current (IZT), with dynamic impedance (ZZT) of 170 Ω measured at 1 kHz with 10% rms ac modulation superimposed on IZT.
The SMBG5380BE3/TR13 exhibits low reverse leakage (IR ≤ 0.5 µA at VR = 91.2 V), stable regulation over -65 °C to +150 °C junction temperature, and withstands solder reflow up to 260 °C for 10 s. Its DO-215AA gull-wing leads enable visual solder joint inspection and meet IPC/JEDEC J-STD-020B Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 120 V ±5% at IZT = 10 mA - defines precise clamping threshold for overvoltage events |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management when operating near max current |
| Dynamic Impedance (ZZT) | 170 Ω at IZT = 10 mA - determines voltage variation under load current changes |
| Max Regulator Current (IZM) | 5.5 mA - maximum continuous DC current before exceeding 5 W rating at VZM = 126 V |
| Surge Current (IZSM) | 1150 A (8.3 ms half-sine) - enables single-event transient suppression without failure |
| Reverse Leakage (IR) | ≤0.5 µA at VR = 91.2 V - ensures minimal standby power loss in high-impedance bias networks |
| Thermal Resistance (RθJA) | 90 °C/W on FR4 (1 oz Cu) - dictates PCB copper area needed for safe thermal dissipation |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; terminals are anode and cathode - no internal circuitry beyond the Zener junction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Positive terminal during reverse-bias operation | Connected to higher-potential node in clamping configuration; polarity must be observed to avoid forward conduction |
| Anode (unbanded end) | Reference/ground terminal during reverse-bias operation | Typically tied to system ground or low-side return path; establishes reference point for regulated voltage |
Key Features
| Feature | Design Value |
|---|---|
| RoHS-compliant matte-tin plating (e3) | Enables lead-free reflow assembly without compromising solderability or corrosion resistance |
| Gull-wing leads (DO-215AA) | Provides visible solder joints for automated optical inspection (AOI) and reduces tombstoning risk |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and floor-life constraints for production handling |
| Non-sensitive to ESD (MIL-STD-750 Method 1020) | Reduces need for special ESD handling during board assembly and testing |
| JEDEC 1N53xxB equivalent | Ensures drop-in compatibility with legacy designs using axial 1N5380B or SMBJ5380B variants |
Applications
| Industrial Power Supply Protection | DC Link Voltage Clamping |
|---|---|

IC Role / Device Role / Timing Role: Passive overvoltage limiter placed across measurement inputs to cap transient excursions. Use Value: Withstands repeated 1000 Vpk fast-risetime pulses due to high IZSM rating and robust junction construction. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5380B | Same electrical specs, but DO-214AA J-bend package instead of DO-215AA gull-wing; RθJA = 85 °C/W vs. 90 °C/W | Preferred where board space allows J-bend footprint and AOI visibility is not required | Select SMBJ5380B if existing layout uses DO-214AA or thermal margin permits slightly lower RθJA |
| 1N5380BRLG | Axial-leaded T-18 package; identical VZ, IZT, and IZM, but RθJA ≈ 50 °C/W with heatsink; no RoHS e3 marking | Suitable for prototyping, through-hole boards, or high-reliability mil-aero systems requiring axial form factor | Choose 1N5380BRLG for manual assembly, repair, or environments where gull-wing solder joint reliability is a concern |
Compared with SMBJ5380B and 1N5380BRLG, the SMBG5380BE3/TR13 offers superior manufacturability for high-density SMT lines via gull-wing visibility and RoHS compliance, while maintaining identical Zener characteristics - making it optimal for volume production of industrial and telecom equipment.

FAQ
What is the Zener voltage tolerance and test current for SMBG5380BE3/TR13?
The SMBG5380BE3/TR13 has a Zener voltage tolerance of ±5% (denoted by the "B" suffix) and is specified at a test current (IZT) of 10 mA. At this current, its nominal VZ is 120 V, ranging from 114 V to 126 V. This tolerance and test condition are confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0246-1 datasheet.
Is SMBG5380BE3/TR13 RoHS compliant and what does the "e3" suffix indicate?
Yes, SMBG5380BE3/TR13 is RoHS compliant. The "e3" suffix explicitly denotes annealed matte-tin plating per JEDEC standard J-STD-609, replacing traditional Sn/Pb finishes. This ensures compatibility with lead-free reflow profiles up to 260 °C for 10 seconds, as verified in the Mechanical and Packaging section of the datasheet.
What is the maximum surge current rating for SMBG5380BE3/TR13 and under what waveform is it defined?
The SMBG5380BE3/TR13 has a maximum non-repetitive surge current (IZSM) of 1150 A, defined for a single 8.3 ms half-sine wave - the industry-standard lightning surge waveform per ANSI/IEEE C62.41. This value is listed in the Electrical Characteristics table and reflects the device's ability to absorb transient energy without failure.
How does the DO-215AA package of SMBG5380BE3/TR13 differ from DO-214AA in practical assembly?
The DO-215AA gull-wing package of SMBG5380BE3/TR13 features outward-bent leads enabling visual solder joint inspection and reduced tombstoning versus the J-bend leads of DO-214AA (used in SMBJ5380B). Its pad layout requires 0.320″ × 0.085″ footprint, and it achieves RθJA = 90 °C/W on FR4 - 5 °C/W higher than DO-214AA's 85 °C/W, necessitating minor thermal design adjustment.
Can SMBG5380BE3/TR13 replace 1N5380B in existing designs?
Yes, SMBG5380BE3/TR13 is functionally equivalent to 1N5380B per the datasheet's statement that "SMBG5333B–SMBG5388B are equivalent to JEDEC registered 1N5333–1N5388B with identical electrical characteristics and testing." However, the surface-mount DO-215AA package requires PCB footprint redesign - it is not a drop-in replacement for the axial T-18 1N5380B.
