Product details
Overview
SMBG5376C/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 87 V, ±2% tolerance (C suffix), and maximum regulator current of 15 mA at 25 °C. It features DO-215AA gull-wing package, 25 °C/W junction-to-lead thermal resistance, and is rated for -65 °C to +150 °C operation. It serves as a precision voltage reference and overvoltage clamp in DC power supply regulation circuits.
For engineers reviewing the SMBG5376C/TR13 datasheet, SMBG5376C/TR13 pinout, SMBG5376C/TR13 application, or SMBG5376C/TR13 equivalent, key selection criteria include Zener voltage tolerance (±2%), dynamic impedance (75 Ω at IZT = 15 mA), reverse leakage (<0.5 µA at 63 V), surge current rating (760 A), and RoHS-compliant matte-tin plating.
Technical Context
This device operates in reverse-bias breakdown mode with tightly controlled VZ = 87 V at IZT = 15 mA, exhibiting low dynamic impedance (ZZT = 75 Ω) and minimal voltage drift over temperature (TJ = -65 °C to +150 °C). Its DO-215AA gull-wing package enables visible solder joints and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity.
The SMBG5376C/TR13 delivers stable regulation across wide current range (IZK = 1.0 mA to IZM = 15 mA), with knee impedance ZZK = 54.5 Ω at 1.0 mA and reverse leakage IR ≤ 0.5 µA at VR = 63 V. It withstands non-repetitive 8.3 ms half-sine surge currents up to 760 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 87 V ±2% at IZT = 15 mA - precise reference voltage for feedback loops and clamping thresholds. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - supports high-energy transient suppression with adequate heat sinking. |
| Dynamic Impedance (ZZT) | 75 Ω at IZT = 15 mA - ensures minimal output voltage variation under load current changes. |
| Reverse Leakage (IR) | ≤0.5 µA at VR = 63 V - guarantees low standby power loss in high-impedance bias networks. |
| Surge Current (IZSM) | 760 A (8.3 ms half-sine) - handles lightning-induced transients and inductive switching spikes. |
| Junction-to-Lead Thermal Resistance | 25 °C/W - enables direct thermal path to PCB copper, critical for sustained 5 W operation. |
| Moisture Sensitivity Level | Level 1 per J-STD-020B - eliminates dry-pack requirement and simplifies SMT assembly logistics. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; banded end must be held positive relative to anode during operation. Terminals are tin-lead or RoHS-compliant matte-tin plated for solderability per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; common reference node in reverse-bias regulation. | Connected to system ground or low-side return path; defines reference potential for VZ measurement. |
| Cathode | Current exit terminal in forward bias; Zener breakdown terminal in reverse bias. | Banded end; connected to regulated rail or clamped node; voltage at this node is stabilized at 87 V ±2%. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5376B | Same VZ = 87 V, but ±5% tolerance and axial T-18 package; higher RθJA = 120 °C/W. | Requires through-hole mounting and larger board area; less suitable for high-density SMT layouts. | Select SMBG5376C/TR13 for surface-mount compatibility, tighter tolerance, and lower thermal resistance. |
| SMBJ5376C | Same VZ, ±2%, and DO-214AA package; RθJA = 100 °C/W; no gull-wing visibility. | Lower surge rating (720 A vs. 760 A); J-bend leads complicate optical inspection and rework. | Choose SMBG5376C/TR13 when visible solder joints, higher surge margin, and JEDEC-equivalent gull-wing form factor are required. |
Compared with 1N5376B and SMBJ5376C, SMBG5376C/TR13 offers the tightest voltage tolerance among surface-mount equivalents, lowest junction-to-lead thermal resistance, and gull-wing geometry enabling automated optical inspection - making it optimal for high-reliability, high-density power regulation where traceability and thermal performance are critical.

FAQ
What is the Zener voltage tolerance of SMBG5376C/TR13?
The SMBG5376C/TR13 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its breakdown voltage is guaranteed between 85.26 V and 88.74 V when measured at IZT = 15 mA and TL = 25 °C. This tighter tolerance supports higher-accuracy voltage references compared to ±5% (B suffix) or ±10% (A suffix) variants of the same SMBG53xx family.
Does SMBG5376C/TR13 require dry-pack storage before SMT assembly?
No, SMBG5376C/TR13 does not require dry-pack storage. It carries IPC/JEDEC J-STD-020B Moisture Sensitivity Level 1, meaning it can be stored indefinitely at ambient conditions (≤30 °C / 85% RH) without baking or desiccant packaging. This simplifies inventory handling and eliminates pre-reflow baking steps in standard SMT processes.
What is the maximum surge current rating for SMBG5376C/TR13?
The SMBG5376C/TR13 is rated for a non-repetitive peak surge current (IZSM) of 760 A, specified for an 8.3 ms half-sine waveform. This rating reflects its ability to absorb high-energy transients-such as those from inductive load switching or ESD events-without permanent degradation, provided the device remains within its thermal limits.
How does the DO-215AA package of SMBG5376C/TR13 differ from DO-214AA?
The DO-215AA package used by SMBG5376C/TR13 features gull-wing leads that extend outward and downward, enabling visual solder joint inspection and improved mechanical strength. In contrast, DO-214AA (used by SMBJ53xx) has J-bend leads that fold under the body, limiting optical access and increasing risk of solder bridging. DO-215AA also provides lower RθJL (25 °C/W vs. ~30 °C/W for DO-214AA).
Is SMBG5376C/TR13 RoHS compliant?
Yes, SMBG5376C/TR13 is RoHS compliant, indicated by the "e3" marking on the device body and confirmed in Microsemi's documentation. It uses annealed matte-tin plating instead of Sn/Pb, meeting EU Directive 2011/65/EU requirements. The part is suitable for lead-free reflow profiles up to 260 °C for 10 seconds.
