Product details
Overview
SMBG5375CE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 82 V, ±2% tolerance (C suffix), rated test current of 15 mA, maximum dynamic impedance of 65 Ω at IZT, and maximum Zener current of 58 mA - used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5375CE3/TR13 datasheet, SMBG5375CE3/TR13 pinout, SMBG5375CE3/TR13 application, or SMBG5375CE3/TR13 equivalent, this page delivers verified electrical parameters, DO-215AA gull-wing package details, thermal derating behavior, surge capability (IZSM = 720 A), and RoHS-compliant matte-tin plating per MIL-STD-750.
Technical Context
This device operates in reverse-bias breakdown mode with tightly controlled VZ = 82 V at IZT = 15 mA, exhibiting low dynamic impedance (ZZT = 65 Ω) and minimal voltage drift across temperature (–65 °C to +150 °C junction range). Its DO-215AA gull-wing package enables visible solder joints and supports high-density PCB layouts.
Thermal resistance is specified as RθJL = 25 °C/W (junction-to-lead) and RθJA = 90 °C/W (junction-to-ambient on FR4), enabling stable regulation up to 5 W at TL < 25 °C. It withstands non-repetitive 8.3 ms half-sine surge currents up to 720 A per IZSM rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 82 V ±2% at 15 mA - defines precise regulation point for feedback networks and clamp thresholds. |
| Power Dissipation (PD) | 5.0 W at lead temperature < 25 °C - requires thermal management when operating near full rating. |
| Dynamic Impedance (ZZT) | 65 Ω at 15 mA - ensures minimal output voltage variation under load transients. |
| Max Reverse Current (IR) | 0.5 µA at VR = 62 V - guarantees low leakage in standby or high-impedance sensing paths. |
| Surge Current (IZSM) | 720 A (8.3 ms half-sine) - provides robust transient overvoltage suppression without failure. |
| Junction Temperature Range | –65 °C to +150 °C - supports operation in industrial, automotive, and aerospace environments. |
| Moisture Sensitivity Level | Level 1 per J-STD-020B - eliminates dry-pack requirement and simplifies SMT handling. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; banded end must be biased positive relative to anode for Zener operation. Weight: 0.1 g. Moisture classification: Level 1 (no dry pack required).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Reverse-bias anode connection point | Connected to regulated rail or clamped node; polarity critical for proper breakdown conduction. |
| Anode (unbanded end) | Reverse-bias cathode reference | Typically tied to ground or lower-potential node; forms return path for Zener current. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5375B equivalent | Identical electrical specs and test methods - enables drop-in replacement in legacy designs. |
| RoHS-compliant matte-tin plating | Solderable per MIL-STD-750 Method 2026 - ensures reliable reflow joint formation and long-term intermetallic stability. |
| Gull-wing lead form | Visible solder fillets on FR4 - supports automated optical inspection (AOI) and reduces voiding risk in high-volume assembly. |
| Level 1 moisture sensitivity | No dry-pack or baking required before SMT - lowers manufacturing cost and avoids moisture-induced popcorning. |
| High surge current rating | 720 A non-repetitive peak - protects downstream circuitry from lightning-induced or inductive-switching transients. |
Applications
| Switch-Mode Power Supply Feedback | Overvoltage Clamp for DC Bus |

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 VZ (82 V), ±5% tolerance (B suffix), identical DO-215AA package and thermal specs. | Lower voltage precision; suitable where ±5% regulation suffices and cost is prioritized. | Select when tighter tolerance is unnecessary and legacy BOM compatibility is required. |
| SMBG5375BE3/TR13 | Same VZ and package, but ±5% tolerance (B suffix) and RoHS-compliant matte-tin finish. | Higher IR (1.0 µA vs. 0.5 µA at 62 V); slightly reduced leakage-sensitive performance. | Choose for RoHS compliance where ±5% tolerance meets design margin and leakage is not critical. |
Compared with SMBG5375CE3/TR13, the 1N5375B offers lower cost and broader legacy support but sacrifices 3% voltage accuracy, while SMBG5375BE3/TR13 maintains RoHS compliance at the expense of leakage performance - making SMBG5375CE3/TR13 optimal for precision feedback and low-leakage clamp roles.

FAQ
What is the Zener voltage tolerance for SMBG5375CE3/TR13?
The "C" suffix in SMBG5375CE3/TR13 indicates a ±2% Zener voltage tolerance at 15 mA test current. This yields a guaranteed VZ range of 80.36 V to 83.64 V under standard test conditions (TL = 25 °C), supporting high-precision regulation where tighter voltage control is required than ±5% devices provide.
Does SMBG5375CE3/TR13 require dry packing before reflow soldering?
No, SMBG5375CE3/TR13 has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it can be stored indefinitely at ambient conditions without desiccant or dry packing. This eliminates pre-reflow baking steps and reduces manufacturing overhead in high-volume SMT lines.
What is the maximum surge current rating for SMBG5375CE3/TR13?
SMBG5375CE3/TR13 is rated for a non-repetitive peak surge current (IZSM) of 720 A with an 8.3 ms half-sine waveform. This value is confirmed in the Electrical Characteristics table on page 3 of the T4-LDS-0246-1 datasheet and reflects its capability to absorb transient energy without parametric shift or catastrophic failure.
How does the DO-215AA package of SMBG5375CE3/TR13 differ from DO-214AA?
The DO-215AA package used by SMBG5375CE3/TR13 features gull-wing leads for visible solder fillets and improved AOI compatibility, whereas DO-214AA uses J-bend leads. Both share similar footprint area, but DO-215AA's lead geometry enhances thermal transfer to the PCB and reduces solder joint voiding risk in automated assembly.
Is SMBG5375CE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5375CE3/TR13 carries the "e3" suffix indicating RoHS-compliant matte-tin plating, qualified for standard lead-free reflow profiles up to 260 °C for 10 seconds. Its thermal resistance (RθJA = 90 °C/W) and moisture Level 1 rating ensure robust performance through typical Pb-free soldering cycles without delamination or solderability loss.
