Product details
Overview
SMBG5375C/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 82 V, ±2% tolerance (C suffix), and maximum regulator current of 15 mA at 25 °C. It uses DO-215AA gull-wing packaging, supports visible solder joints, and operates across –65 °C to +150 °C junction temperature for voltage regulation in power supply feedback loops.
For engineers reviewing the SMBG5375C/TR13 datasheet, SMBG5375C/TR13 pinout, SMBG5375C/TR13 application, or SMBG5375C/TR13 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (25 °C/W junction-to-lead), surge current rating (720 A @ 8.3 ms), moisture sensitivity level (MSL 1), and RoHS-compliant matte-tin plating.
Technical Context
This device functions as a precision shunt voltage reference in DC power regulation circuits, maintaining stable output voltage under varying load and line conditions. Its low dynamic impedance (65 Ω at IZT = 15 mA) ensures minimal voltage deviation across operating current range.
The SMBG5375C/TR13 is rated for 5.0 W dissipation at lead temperature <25 °C, with thermal resistance junction-to-lead of 25 °C/W and junction-to-ambient of 90 °C/W on FR4 board. It withstands non-repetitive 8.3 ms half-sine surge currents up to 720 A per JEDEC test method.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 82 V ±2% at IZT = 15 mA - defines precise regulation point for feedback networks |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management via PCB copper pour or heatsink |
| Dynamic Impedance (ZZT) | 65 Ω at 15 mA - limits output voltage variation under load transients |
| Max Surge Current (IZSM) | 720 A (8.3 ms half-sine) - enables robust protection against line surges |
| Junction Temperature Range | –65 °C to +150 °C - supports operation in automotive under-hood and industrial environments |
| Moisture Sensitivity Level | MSL 1 - no dry pack required; simplifies SMT assembly logistics |
| Forward Voltage (VF) | 1.2 V @ 1.0 A - confirms low-conduction loss in forward-biased fault conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5375B | Axial-leaded T-18 package; same VZ, IZM, and ZZT; no gull-wing geometry | Requires through-hole assembly; unsuitable for high-density SMT layouts | Select when legacy through-hole design or manual prototyping is required |
| SMBJ5375C | DO-214AA J-bend package; identical electrical specs but different thermal resistance (RθJA = 100 °C/W) | Lower power derating on FR4 due to higher junction-to-ambient resistance | Select when existing DO-214AA footprint must be retained and thermal margin allows |
Compared with SMBG5375C/TR13, the 1N5375B offers identical regulation performance but lacks SMT compatibility, while SMBJ5375C matches the surface-mount form factor but delivers lower thermal efficiency on standard PCBs.

FAQ
What is the Zener voltage tolerance for SMBG5375C/TR13?
The SMBG5375C/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 80.36 V and 83.64 V at the specified test current of 15 mA and lead temperature of 25 °C, enabling high-accuracy voltage references without external trimming.
Does SMBG5375C/TR13 require dry packing before SMT assembly?
No, SMBG5375C/TR13 has a moisture sensitivity level (MSL) of 1 per IPC/JEDEC J-STD-020B, meaning it can be stored indefinitely at ambient conditions without dry pack or baking. This eliminates moisture-related defects like popcorning during reflow and simplifies manufacturing logistics for high-volume production.
What is the maximum surge current rating for SMBG5375C/TR13?
The SMBG5375C/TR13 is rated for a non-repetitive peak surge current (IZSM) of 720 A at an 8.3 ms half-sine waveform, per JEDEC test standards. This rating supports robust transient suppression in 48 V industrial buses and automotive load-dump scenarios without degradation of Zener characteristics.
How does the DO-215AA package of SMBG5375C/TR13 differ from DO-214AA?
The DO-215AA gull-wing package of SMBG5375C/TR13 provides visible solder joints for automated optical inspection, whereas DO-214AA uses J-bend leads that hide solder fillets. DO-215AA also achieves lower junction-to-lead thermal resistance (25 °C/W vs. ~30 °C/W for DO-214AA), improving power handling in thermally constrained layouts.
Is SMBG5375C/TR13 RoHS compliant?
Yes, SMBG5375C/TR13 features RoHS-compliant annealed matte-tin plating per the "e3" designation implied by the "C" suffix and confirmed in Microsemi's documentation. It meets EU Directive 2011/65/EU and contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits.
