Product details
Overview
SMBG5367B/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 43 V, ±5% tolerance (B suffix), 30 mA test current, and 20 Ω dynamic impedance at IZT. It operates from –65 °C to +150 °C and is used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5367B/TR13 datasheet, SMBG5367B/TR13 pinout, SMBG5367B/TR13 application, or SMBG5367B/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current capability (2.8 A), thermal resistance (25 °C/W junction-to-lead), and DO-215AA gull-wing package compatibility with high-density PCB layouts.
Technical Context
This device functions as a two-terminal voltage reference operating in reverse breakdown, with specified Zener voltage measured at 30 mA DC current and 30 °C lead temperature. Its 20 Ω dynamic impedance ensures stable regulation under varying load currents, and its 2.8 A non-repetitive surge rating supports transient overvoltage clamping per MIL-STD-750 method 3012.
The SMBG5367B/TR13 uses a void-free thermosetting epoxy case (UL94V-0), matte-tin RoHS-compliant plating, and cathode polarity marked by a band. It meets moisture sensitivity level 1 per J-STD-020B and requires no dry pack prior to reflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 43 V ±5% at 30 mA - defines regulated output voltage in feedback or clamp circuits |
| Power Dissipation (PD) | 5.0 W at TL ≤ 25 °C - sets maximum continuous power handling with adequate heatsinking |
| Dynamic Impedance (ZZT) | 20 Ω at IZT = 30 mA - determines voltage deviation under load current variation |
| Max Surge Current (IZSM) | 2.8 A (8.3 ms half-sine) - enables single-event transient suppression without failure |
| Junction-to-Lead RθJL | 25 °C/W - allows thermal design using lead temperature as proxy for junction temp |
| Reverse Leakage (IR) | 0.5 µA at 32.7 V - ensures minimal standby power loss in high-impedance bias networks |
| Operating Temperature | –65 °C to +150 °C - supports industrial and automotive under-hood applications |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5367B | Axial-leaded T-18 package; identical VZ, IZT, ZZT, and PD; higher RθJA (125 °C/W) | Requires through-hole mounting and larger board area; unsuitable for automated SMT lines | Select when manual assembly or legacy through-hole design mandates axial form factor |
| SMBJ5367 | DO-214AA J-bend package; same VZ and tolerance; 100 mA IZM; 30 Ω ZZT | Lower surge rating (2.2 A) and higher dynamic impedance reduce regulation stability under fast transients | Select when DO-214AA footprint is fixed and 43 V ±5% regulation suffices with relaxed ZZT requirement |
Compared with SMBG5367B/TR13, 1N5367B offers identical electrical performance but demands through-hole assembly, while SMBJ5367 trades surge robustness and regulation precision for DO-214AA compatibility - making SMBG5367B/TR13 optimal for high-density SMT designs requiring tight voltage control and high-energy transient immunity.

FAQ
What is the Zener voltage tolerance for SMBG5367B/TR13?
The 'B' suffix in SMBG5367B/TR13 denotes ±5% Zener voltage tolerance, meaning the actual breakdown voltage falls between 40.85 V and 45.15 V when measured at 30 mA and 30 °C lead temperature. This tolerance is verified per JEDEC test methods and applies across the full operating temperature range of –65 °C to +150 °C.
Can SMBG5367B/TR13 be used in place of 1N5367B?
Yes, SMBG5367B/TR13 is electrically equivalent to 1N5367B per Microsemi documentation, sharing identical VZ, IZT, ZZT, IZM, and surge ratings. However, SMBG5367B/TR13 uses a DO-215AA gull-wing package versus the axial T-18 of 1N5367B - requiring PCB layout change but enabling automated SMT assembly.
What is the maximum continuous power dissipation for SMBG5367B/TR13?
SMBG5367B/TR13 is rated for 5.0 W continuous power dissipation when lead temperature (TL) is maintained at or below 25 °C. Derating begins above 25 °C at 55.6 mW/°C, based on its 25 °C/W junction-to-lead thermal resistance - not the 90 °C/W junction-to-ambient value which assumes minimal copper area.
Does SMBG5367B/TR13 require dry packing before reflow soldering?
No, SMBG5367B/TR13 has a moisture sensitivity level (MSL) of 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ambient conditions without baking or dry pack. This eliminates pre-reflow moisture removal steps and reduces manufacturing overhead in high-volume SMT lines.
What is the reverse leakage current specification for SMBG5367B/TR13?
SMBG5367B/TR13 specifies a maximum reverse leakage current (IR) of 0.5 µA at 32.7 V (76% of VZ). This low leakage ensures minimal power loss in high-impedance bias networks and preserves accuracy in precision reference applications where current draw must remain below 1 µA.
