Product details
Overview
SMBG5367BE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 43 V, ±5% tolerance (B suffix), 20 Ω dynamic impedance at 30 mA test current, and DO-215AA gull-wing package. It regulates voltage across wide current/temperature ranges and withstands high surge stresses in power supply protection circuits.
For engineers reviewing the SMBG5367BE3/TR13 datasheet, SMBG5367BE3/TR13 pinout, SMBG5367BE3/TR13 application, or SMBG5367BE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current rating (2.8 A), thermal resistance (90 °C/W on FR4), and RoHS-compliant matte-tin plating for lead-free assembly.
Technical Context
This device operates as a precision voltage reference and overvoltage clamp in DC power rails. Its 43 V breakdown voltage is specified at 30 mA (IZT), with 20 Ω dynamic impedance (ZZT) ensuring stable regulation under load variation. The DO-215AA gull-wing package enables visible solder joints and supports automated optical inspection.
Thermal performance is defined by RθJA = 90 °C/W on FR4 (1 oz Cu) and RθJL = 25 °C/W to lead, enabling 5.0 W dissipation only when lead temperature remains ≤25 °C. Reverse leakage is limited to 0.5 µA at VR = 32.7 V, confirming low standby power loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 43 V ±5% at IZT = 30 mA - defines regulated output voltage with tight tolerance for feedback loop stability |
| Power Dissipation (PD) | 5.0 W at TL ≤ 25 °C - requires thermal management via PCB copper pour or heatsink attachment to leads |
| Dynamic Impedance (ZZT) | 20 Ω at IZT = 30 mA - ensures minimal output voltage shift under dynamic load changes |
| Max Surge Current (IZSM) | 2.8 A (8.3 ms half-sine) - protects downstream circuitry from transient overvoltage events |
| Reverse Leakage (IR) | 0.5 µA at VR = 32.7 V - guarantees negligible quiescent current in standby mode |
| Thermal Resistance (RθJA) | 90 °C/W on FR4 - dictates minimum copper area needed to maintain junction temperature <150 °C |
| Junction Temperature Range | –65 to +150 °C - supports operation in industrial and automotive under-hood environments |
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. Leads are RoHS-compliant matte-tin plated and solderable per MIL-STD-750 method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-bias operation | Connected to system ground or lower-potential rail; forms return path for Zener current |
| Cathode | Regulated output node | Banded terminal connected to voltage rail being clamped; maintains 43 V relative to anode |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5367B equivalent | Identical electrical specs and test methods - enables drop-in replacement in legacy designs |
| Moisture Sensitivity Level 1 | No dry pack required - eliminates baking step before reflow, reducing manufacturing cost and risk |
| Gull-wing lead form | Visible solder fillets - supports AOI and X-ray inspection without additional test fixtures |
| High surge current capability | 2.8 A non-repetitive peak - absorbs IEC 61000-4-5 Level 4 surges without degradation |
| Low dynamic impedance | 20 Ω at 30 mA - maintains regulation within ±0.6 V over 10–100 mA load 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 |
|---|---|---|---|
| 1N5367B | Same 43 V ±5%, 5 W rating, but axial DO-204AL (T-18) package with leaded through-hole mounting. | Requires PCB through-hole holes and wave soldering; unsuitable for high-density SMT layouts. | Select when legacy board reuse or manual prototyping demands axial form factor and higher mechanical robustness. |
| SMBJ5367B | Identical electrical specs but DO-214AA (J-bend) package; RθJA = 100 °C/W vs. 90 °C/W for SMBG5367BE3/TR13. | Lower thermal efficiency on FR4; requires larger copper area to achieve same power derating curve. | Select when existing footprint uses J-bend geometry or when compatibility with SMBJ-series tape-and-reel logistics is prioritized. |
Compared with 1N5367B and SMBJ5367B, SMBG5367BE3/TR13 offers superior thermal performance (90 °C/W), gull-wing visibility for AOI, and RoHS compliance - making it optimal for new SMT designs requiring high reliability and automated inspection.

FAQ
What is the Zener voltage tolerance for SMBG5367BE3/TR13?
The "B" suffix in SMBG5367BE3/TR13 indicates a ±5% Zener voltage tolerance. At 30 mA test current (IZT), the measured VZ falls between 40.85 V and 45.15 V. This tolerance is verified per JEDEC test methods and applies across the full operating temperature range of –65 to +150 °C.
Does SMBG5367BE3/TR13 require dry packing before reflow soldering?
No. SMBG5367BE3/TR13 has IPC/JEDEC J-STD-020B Moisture Sensitivity Level 1, meaning it may be stored indefinitely at ambient conditions without desiccant or dry pack. This eliminates pre-reflow baking steps and reduces process complexity in high-volume SMT lines.
What is the maximum surge current rating for SMBG5367BE3/TR13?
SMBG5367BE3/TR13 is rated for 2.8 A peak non-repetitive surge current (IZSM) under 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 capability to absorb IEC 61000-4-5 Level 4 transients.
How does the DO-215AA package of SMBG5367BE3/TR13 differ from DO-214AA?
The DO-215AA gull-wing package of SMBG5367BE3/TR13 provides visible solder joints for AOI, whereas DO-214AA (used in SMBJ5367B) has J-bend leads that hide solder fillets. DO-215AA also achieves lower RθJA (90 °C/W vs. 100 °C/W) due to improved thermal path from die to PCB via gull-wing leads.
Is SMBG5367BE3/TR13 compatible with lead-free reflow profiles?
Yes. SMBG5367BE3/TR13 features RoHS-compliant matte-tin plating (denoted by "e3") and is qualified for standard lead-free reflow profiles with peak temperature up to 260 °C for 10 seconds. Its thermosetting epoxy body meets UL94V-0 flammability requirements.
