Product details
Overview
SMBG5375BE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 82 V, ±5% tolerance (B suffix), rated test current of 15 mA, maximum dynamic impedance of 65 Ω at IZT, and maximum regulator current of 58 mA - used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5375BE3/TR13 datasheet, SMBG5375BE3/TR13 pinout, SMBG5375BE3/TR13 application, or SMBG5375BE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current capability (720 A), thermal resistance (25 °C/W junction-to-lead), RoHS-compliant matte-tin plating, and DO-215AA gull-wing package compatibility with automated SMT assembly.
Technical Context
This device operates in reverse breakdown to maintain stable voltage across wide current (15 mA to 58 mA) and temperature (-65 °C to +150 °C) ranges. Its low dynamic impedance (65 Ω at 15 mA) ensures minimal voltage variation under load transients.
The SMBG5375BE3/TR13 features a moisture sensitivity level 1 rating per J-STD-020B, eliminating dry-pack requirements, and withstands 8.3 ms half-sine surge currents up to 720 A - critical for transient suppression in industrial power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 82 V ±5% at 15 mA - defines precise regulation point for feedback networks. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management via lead conduction (RθJL = 25 °C/W). |
| Dynamic Impedance (ZZT) | 65 Ω max at 15 mA - limits output voltage deviation during current changes. |
| Maximum Regulator Current (IZM) | 58 mA - sets upper DC operating limit before thermal derating. |
| Surge Current (IZSM) | 720 A (8.3 ms half-sine) - enables robust transient clamping without failure. |
| Reverse Leakage (IR) | 0.5 µA at 65.5 V - ensures negligible standby power loss in high-impedance bias networks. |
| Junction Temperature Range | -65 °C to +150 °C - supports operation in extended-temperature industrial and automotive environments. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; leads are tin-plated (RoHS-compliant matte-tin per e3 suffix); weight: 0.1 g; moisture sensitivity level 1 (no dry pack required).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Breakdown terminal | Connected to regulated node; must be held positive relative to anode for Zener operation. |
| Anode | Reference terminal | Typically tied to ground or lower-potential rail; completes reverse-bias path. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5375B equivalent | Identical electrical specs and test methods - enables drop-in replacement in legacy designs. |
| Gull-wing lead form (DO-215AA) | Enables visual solder joint inspection and reliable reflow yield on FR4 PCBs. |
| Level 1 moisture sensitivity | Eliminates baking and dry-pack logistics - reduces manufacturing overhead and handling risk. |
| High surge current rating | 720 A peak (8.3 ms) supports IEC 61000-4-5 compliance in AC/DC front-end protection. |
| Low dynamic impedance | 65 Ω at 15 mA ensures <±0.5 V regulation shift across full operating current range. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5375B | Same Zener voltage (82 V), ±5%, but axial T-18 package; higher RθJA (125 °C/W vs. 90 °C/W). | Through-hole mounting only; unsuitable for high-density SMT layouts. | Select when legacy through-hole assembly or manual prototyping is required. |
| SMBJ5375B | Identical electrical specs, same DO-214AA (J-bend) package; RθJL not specified; no Level 1 moisture rating. | Requires dry pack handling; less visible solder joints than gull-wing SMBG variant. | Select when DO-214AA footprint is already standardized and moisture sensitivity is managed externally. |
Compared with SMBG5375BE3/TR13, 1N5375B demands PCB redesign for through-hole placement and offers inferior thermal performance, while SMBJ5375B sacrifices solder-joint inspectability and adds moisture-handling overhead - making SMBG5375BE3/TR13 optimal for new SMT designs requiring reliability, manufacturability, and compliance.

FAQ
What is the Zener voltage tolerance for SMBG5375BE3/TR13?
The 'B' suffix in SMBG5375BE3/TR13 specifies a ±5% Zener voltage tolerance, meaning its actual breakdown voltage falls between 77.9 V and 86.1 V when measured at 15 mA and 25 °C. This tolerance is verified per JEDEC test methods and applies across the full operating temperature range of -65 °C to +150 °C. The SMBG5375BE3/TR13 maintains this specification without derating under standard SMT mounting conditions.
Does SMBG5375BE3/TR13 require dry packing before reflow soldering?
No, SMBG5375BE3/TR13 has a moisture sensitivity level (MSL) of 1 per IPC/JEDEC J-STD-020B, which means it can be stored indefinitely at ambient conditions without desiccant or dry packing. This eliminates baking steps prior to reflow, reducing process complexity and avoiding thermal stress on the device. The SMBG5375BE3/TR13 achieves MSL 1 due to its void-free epoxy encapsulation and controlled moisture diffusion properties.
What is the maximum continuous DC current for SMBG5375BE3/TR13?
The maximum continuous regulator current (IZM) for SMBG5375BE3/TR13 is 58 mA when operated at lead temperature (TL) below 25 °C. At higher lead temperatures, power dissipation must be derated linearly using the 25 °C/W junction-to-lead thermal resistance. This value is calculated per Note 3 in the datasheet: IZM = P / VZM, where VZM = 86.1 V (upper limit of ±5%) and P = 5.0 W.
How does SMBG5375BE3/TR13 compare to the 1N5375B in terms of thermal performance?
SMBG5375BE3/TR13 offers superior thermal performance versus 1N5375B: its junction-to-lead thermal resistance is 25 °C/W, compared to ~125 °C/W for the axial T-18 packaged 1N5375B. This allows SMBG5375BE3/TR13 to sustain full 5 W dissipation with minimal temperature rise when properly soldered to copper pads, whereas 1N5375B requires significant heatsinking. Both share identical Zener voltage and tolerance specs.
Is SMBG5375BE3/TR13 suitable for IEC 61000-4-5 surge protection?
Yes, SMBG5375BE3/TR13 is rated for 720 A non-repetitive peak surge current (IZSM) on an 8.3 ms half-sine waveform - exceeding the 400 A requirement for IEC 61000-4-5 Level 4 (2 kV line-to-earth) testing. Its low dynamic impedance (65 Ω) and fast response ensure effective clamping without thermal runaway. For sustained protection, pairing with a series impedance (e.g., PTC or resistor) is recommended in final SMBG5375BE3/TR13 implementations.
