Product details
Overview
SMBG5367CE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 43 V, ±2% tolerance (C suffix), and maximum Zener current IZM of 190 mA at TL < 25 °C. It uses DO-215AA gull-wing package, delivers low dynamic impedance (20 Ω at IZT = 30 mA), and is rated for surge current up to 2.8 A (8.3 ms half-sine). It serves as precision voltage reference and overvoltage clamp in DC power rails.
For engineers reviewing the SMBG5367CE3/TR13 datasheet, SMBG5367CE3/TR13 pinout, SMBG5367CE3/TR13 application, or SMBG5367CE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (RθJL = 25 °C/W), surge robustness (IZSM = 2.8 A), moisture sensitivity level (MSL Level 1), and RoHS-compliant matte-tin plating.
Technical Context
This device operates in reverse-biased breakdown mode, regulating voltage across wide current ranges (IZK = 1.0 mA to IZM = 190 mA) with minimal voltage drift versus temperature (−65 to +150 °C junction range). Its low knee impedance (ZZK = 20 Ω @ 1 mA) ensures stable regulation near the breakdown threshold.
The DO-215AA gull-wing package enables visible solder joints and supports high-density PCB layouts. Thermal performance relies on lead-to-board conduction (RθJL = 25 °C/W) rather than ambient convection (RθJA = 90 °C/W), requiring proper copper pour under the leads for full 5 W dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 43 V ±2% at IZT = 30 mA - defines precise clamping/reference point for 42.14–43.86 V operation |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management via copper pour or heatsinked leads |
| Dynamic Impedance (ZZT) | 20 Ω at IZT = 30 mA - ensures <0.6 V variation over ±10 mA load change near regulation point |
| Max Surge Current (IZSM) | 2.8 A (8.3 ms half-sine) - withstands transient overvoltage events without degradation |
| Junction Temp Range | −65 to +150 °C - supports industrial and automotive under-hood environments |
| Moisture Sensitivity | Level 1 per J-STD-020B - no dry pack or baking required before reflow |
| Forward Voltage (VF) | 1.2 V @ 1.0 A - enables use as polarity protection diode in series with load |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; terminals are anode (unbanded end) and cathode (banded end); designed for visible solder inspection and FR4 board mounting with recommended 8.13 mm × 2.16 mm pad layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; referenced ground in reverse-bias clamp | Connected to lower-potential node (e.g., GND or return path) during Zener operation |
| Cathode | Current exit terminal in forward bias; regulated output node in reverse bias | Banded end connects to voltage rail being clamped or referenced; carries full IZM current |
Key Features
| Feature | Design Value |
|---|---|

| RoHS-compliant matte-tin plating | e3 suffix confirms lead-free finish compliant with IPC-J-STD-020B and JEDEC Level 1 handling |
| Low-profile gull-wing leads | Enables automated optical inspection (AOI) of solder joints and reduces board height vs. axial packages |
| High surge current rating | 2.8 A non-repetitive surge capability protects downstream circuitry from ESD and load-dump transients |
| Stable regulation over temperature | ±0.07%/°C typical TCZ ensures <±0.3 V drift from −40 to +85 °C ambient |
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 VZ = 43 V, ±5% tolerance (B suffix), higher ZZT = 20 Ω but wider tolerance band | Acceptable where ±5% regulation accuracy suffices; lower cost but reduced precision | Select when budget constraints outweigh need for ±2% voltage stability |
| SMBG5367B | Identical VZ = 43 V, ±5% tolerance, same DO-215AA package and thermal specs | RoHS-noncompliant Sn/Pb plating; not suitable for lead-free assembly processes | Choose only for legacy repair or non-RoHS production lines with Pb-based solder |
Compared with SMBG5367CE3/TR13, 1N5367B offers lower cost but sacrifices voltage accuracy, while SMBG5367B matches form/fit/function but lacks RoHS compliance-making SMBG5367CE3/TR13 the optimal choice for new designs requiring precision and environmental compliance.

FAQ
What is the Zener voltage tolerance of SMBG5367CE3/TR13?
The SMBG5367CE3/TR13 has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in its part number. This means its breakdown voltage is guaranteed between 42.14 V and 43.86 V when tested at 30 mA (IZT) and TL = 25 °C. The tighter tolerance supports precision regulation tasks where ±5% devices like SMBG5367B would introduce unacceptable error.
Can SMBG5367CE3/TR13 replace 1N5367B in existing designs?
Yes, SMBG5367CE3/TR13 is a direct surface-mount replacement for through-hole 1N5367B in terms of electrical characteristics and JEDEC registration. However, it uses DO-215AA gull-wing packaging instead of DO-41, so PCB layout must be updated. The e3 RoHS compliance and ±2% tolerance further improve performance over the legacy part.
What is the maximum continuous Zener current for SMBG5367CE3/TR13?
The maximum continuous Zener current (IZM) for SMBG5367CE3/TR13 is 190 mA when lead temperature (TL) is maintained below 25 °C. At higher lead temperatures, power derating applies per Figure 1 in the datasheet; for example, at TL = 75 °C, IZM drops to approximately 133 mA to stay within the 5 W power limit.
Does SMBG5367CE3/TR13 require dry packing before reflow soldering?
No, SMBG5367CE3/TR13 has a moisture sensitivity level (MSL) of Level 1 per J-STD-020B, meaning it can be stored indefinitely at ambient conditions without dry packing or baking prior to reflow. This simplifies manufacturing logistics and eliminates pre-reflow bake cycles required for higher-MSL components.
What is the surge current rating of SMBG5367CE3/TR13 and how is it defined?
SMBG5367CE3/TR13 is rated for a non-repetitive peak surge current (IZSM) of 2.8 A, defined as the maximum current for a single 8.3 ms half-sine waveform. This rating reflects its ability to absorb transient energy without parametric shift or catastrophic failure, making it suitable for ISO 7637-2 and IEC 61000-4-5 surge protection applications.
