Product details
Overview
SMBG5367C/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 43 V, ±2% tolerance (C suffix), 20 mA test current (IZT), 20 Ω dynamic impedance (ZZT), and 190 mA maximum regulator current (IZM). It operates in the DO-215AA gull-wing package and is used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5367C/TR13 datasheet, SMBG5367C/TR13 pinout, SMBG5367C/TR13 application, or SMBG5367C/TR13 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (RθJL = 25 °C/W), surge current capability (IZSM = 2.8 A), and RoHS-compliant matte-tin plating for lead-free assembly.
Technical Context
This device functions as a two-terminal voltage reference diode operating in reverse breakdown. Its Zener voltage is specified at 43 V ±2% under 20 mA DC test current (IZT), with dynamic impedance measured at 20 Ω using 10% rms AC modulation superimposed on IZT.
Thermal performance is defined by junction-to-lead resistance of 25 °C/W and junction-to-ambient resistance of 90 °C/W on FR4 board (1 oz Cu). It withstands 2.8 A non-repetitive 8.3 ms half-sine surge current and exhibits ≤0.5 µA reverse leakage at VR = 32.7 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 43 V ±2% at 20 mA - ensures tight regulation in feedback networks requiring stable reference under load variation. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - supports high-energy clamping without heatsink when lead temperature is controlled. |
| Dynamic Impedance (ZZT) | 20 Ω at IZT = 20 mA - minimizes output voltage deviation during transient current changes in regulation circuits. |
| Max Regulator Current (IZM) | 190 mA - defines safe continuous DC current limit before thermal runaway at rated power. |
| Surge Current (IZSM) | 2.8 A (8.3 ms half-sine) - enables robust transient overvoltage suppression in industrial power rails. |
| Reverse Leakage (IR) | ≤0.5 µA at VR = 32.7 V - guarantees low standby power loss in high-impedance bias networks. |
| Thermal Resistance (RθJL) | 25 °C/W - allows accurate junction temperature estimation from lead temperature measurement in PCB layout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5367B | Through-hole DO-41 package; identical VZ, IZT, ZZT, and IZM specs; Sn/Pb plating standard. | Requires axial-leaded PCB footprint and wave soldering; not suitable for high-density SMT layouts. | Select when legacy through-hole assembly is mandated or thermal mass of DO-41 improves surge handling in non-SMT environments. |
| SMBG5367B | Same DO-215AA package but ±5% tolerance (B suffix); otherwise identical electrical characteristics. | Lower cost option where 43 V ±5% (40.85–45.15 V) meets system margin requirements. | Select when tighter 43 V ±2% regulation is unnecessary and BOM cost reduction is prioritized over reference precision. |

FAQ
What is the Zener voltage tolerance of SMBG5367C/TR13?
The SMBG5367C/TR13 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its actual breakdown voltage falls within 42.14 V to 43.86 V when measured at 20 mA DC test current and 25 °C ambient temperature, per Microsemi's T4-LDS-0246-1 datasheet specifications.
Does SMBG5367C/TR13 require dry packing before reflow soldering?
No, SMBG5367C/TR13 does not require dry packing. It carries IPC/JEDEC J-STD-020B moisture sensitivity level 1 rating, meaning it can be stored indefinitely at ambient conditions without desiccant or baking prior to reflow soldering-reducing manufacturing overhead and preventing moisture-induced popcorning.
What is the maximum surge current rating for SMBG5367C/TR13?
The SMBG5367C/TR13 is rated for a non-repetitive peak surge current (IZSM) of 2.8 A, defined as the maximum value of an 8.3 ms half-sine waveform. This rating enables reliable transient voltage suppression in automotive load-dump and industrial inductive switching events without permanent degradation.
Is SMBG5367C/TR13 RoHS compliant?
Yes, SMBG5367C/TR13 is RoHS compliant, indicated by the "e3" marking variant and matte-tin plating per MIL-STD-750 method 2026. It contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE, meeting EU Directive 2011/65/EU and supporting lead-free reflow profiles up to 260 °C for 10 seconds.
How does SMBG5367C/TR13 compare to SMBG5367B in terms of voltage regulation accuracy?
SMBG5367C/TR13 provides ±2% Zener voltage tolerance versus ±5% for SMBG5367B, delivering tighter regulation (42.14–43.86 V vs. 40.85–45.15 V). Both share identical package, power rating, and thermal resistance, but SMBG5367C/TR13 is preferred where feedback loop accuracy or overvoltage trip point precision is critical.
