Product details
Overview
SMBG5380B/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 120 V, ±5% tolerance (B suffix), and maximum regulator current of 10 mA at 25 °C. It features DO-215AA gull-wing package, 25 °C/W junction-to-lead thermal resistance, and is rated for operation from –65 °C to +150 °C. It serves as a precision voltage reference or overvoltage clamp in industrial power supply feedback loops.
For engineers reviewing the SMBG5380B/TR13 datasheet, SMBG5380B/TR13 pinout, SMBG5380B/TR13 application, or SMBG5380B/TR13 equivalent, key selection criteria include its 120 V Zener voltage, 5 W power rating at lead temperature <25 °C, 170 Ω dynamic impedance at IZT = 10 mA, RoHS-compliant matte-tin plating, and DO-215AA gull-wing footprint compatibility with high-density PCB layouts.
Technical Context
This device operates in reverse-bias breakdown mode with a specified Zener voltage of 120 V measured at 10 mA test current (IZT) and 30 °C lead temperature. Its dynamic impedance (ZZT) is 170 Ω, indicating moderate regulation sensitivity to current variation near IZT.
The SMBG5380B/TR13 exhibits a maximum reverse leakage current of 0.5 µA at VR = 91.2 V and supports non-repetitive surge currents up to 1150 A (8.3 ms half-sine). Thermal design must account for RθJL = 25 °C/W and derating per Figure 1 when lead temperature exceeds 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 120 V ±5% at IZT = 10 mA - defines stable regulation point for feedback or clamping circuits |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management via copper pour or heatsinked lead |
| Dynamic Impedance (ZZT) | 170 Ω at IZT = 10 mA - determines output voltage variation under load current changes |
| Max Reverse Current (IR) | 0.5 µA at VR = 91.2 V - ensures low standby leakage in high-impedance bias networks |
| Junction Temperature Range | –65 °C to +150 °C - supports operation in extended industrial and automotive under-hood environments |
| Thermal Resistance (RθJL) | 25 °C/W - enables accurate junction temperature estimation from measured lead temperature |
| Package | DO-215AA gull-wing - provides visible solder joints and IPC/JEDEC Level 1 moisture sensitivity |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; terminals are anode (unbanded end) and cathode (banded end); polarity must be observed during placement-cathode is positive relative to anode in regulation mode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reverse-bias current sink terminal | Connected to lower-potential node (e.g., ground or feedback divider low-side); carries full Zener current during regulation |
| Cathode | Reverse-bias voltage reference terminal | Connected to higher-potential node (e.g., supply rail or feedback divider high-side); establishes regulated 120 V reference |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5380B equivalent | Identical electrical characteristics and test methods to legacy through-hole 1N5380B, enabling drop-in replacement in upgraded SMT designs |
| Gull-wing lead form | Enables visual solder joint inspection and reliable reflow attachment on FR4 boards without tombstoning risk |
| Level 1 moisture sensitivity | No dry pack or baking required before assembly-reduces manufacturing overhead and handling complexity |
| RoHS-compliant matte-tin plating | Meets EU RoHS Directive 2011/65/EU and supports Pb-free reflow profiles up to 260 °C for 10 seconds |
| High surge current rating | 1150 A non-repetitive (8.3 ms half-sine) withstand capability-suitable for transient overvoltage suppression in DC bus lines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5380B | Through-hole DO-41 package; identical VZ, IZT, ZZT, and IR specs; same ±5% tolerance and 5 W rating. | Requires axial-leaded PCB footprint and wave soldering; unsuitable for high-density SMT assemblies. | Select 1N5380B only when legacy through-hole assembly or manual prototyping is required. |
| SMBJ5380B | Same Zener parameters but in DO-214AA (J-bend) package; RθJA = 90 °C/W vs. SMBG's 25 °C/W; no gull-wing visibility. | Limited thermal performance in high-power continuous operation; less suitable for sustained 5 W dissipation without heatsinking. | Choose SMBJ5380B only if board space constraints favor J-bend geometry and thermal load remains below 1.38 W ambient-limited rating. |
Compared with 1N5380B and SMBJ5380B, SMBG5380B/TR13 offers superior thermal transfer via gull-wing leads (RθJL = 25 °C/W), visible solder joints for AOI, and seamless SMT integration-making it optimal for production-grade 5 W Zener applications where reliability and manufacturability are critical.

FAQ
What is the Zener voltage tolerance of SMBG5380B/TR13?
The "B" suffix in SMBG5380B/TR13 indicates a ±5% Zener voltage tolerance. At 25 °C, its nominal VZ is 120 V, so the actual measured value falls between 114 V and 126 V. This tolerance is confirmed in the Electrical Characteristics table on page 3 of the T4-LDS-0246-1 datasheet, where SMBG5380B is explicitly listed with IZT = 10 mA and VZ = 120 V.
Can SMBG5380B/TR13 replace 1N5380B in existing designs?
Yes-SMBG5380B/TR13 is functionally and electrically equivalent to 1N5380B per Microsemi documentation, sharing identical VZ, IZT, ZZT, IR, and power ratings. However, the DO-215AA gull-wing package requires PCB footprint revision; it is not a mechanical drop-in replacement but a validated SMT upgrade path for the same 120 V, 5 W Zener function.
What is the maximum continuous power dissipation for SMBG5380B/TR13?
SMBG5380B/TR13 is rated for 5.0 W continuous power dissipation only when lead temperature (TL) is maintained below 25 °C. At 25 °C ambient on FR4 with recommended footprint, its usable power drops to 1.38 W due to RθJA = 90 °C/W. Derating follows the curve in Figure 1 of the datasheet, with zero power allowed above 150 °C junction temperature.
Is SMBG5380B/TR13 RoHS compliant?
Yes-SMBG5380B/TR13 uses RoHS-compliant annealed matte-tin plating per MIL-STD-750 method 2026, as stated in the Mechanical and Packaging section (page 2) and confirmed by the "TR13" tape-and-reel suffix aligned with EIA-481-1-A standards. It meets EU Directive 2011/65/EU and supports Pb-free reflow up to 260 °C for 10 seconds.
What is the reverse leakage current specification for SMBG5380B/TR13?
SMBG5380B/TR13 has a maximum reverse leakage current (IR) of 0.5 µA at VR = 91.2 V, as specified in the Electrical Characteristics table (page 3). This low leakage ensures minimal error in high-impedance reference or bias networks and is verified under standard test conditions at TL = 30 °C.
