Product details
Overview
SMBG5365A/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 36 V, ±10% tolerance (A suffix), 30 mA test current (IZT), and 132 Ω dynamic impedance (ZZT) at IZT. It regulates voltage in power supply rails and overvoltage protection circuits across industrial control and telecom infrastructure.
For engineers reviewing the SMBG5365A/TR13 datasheet, SMBG5365A/TR13 pinout, SMBG5365A/TR13 application, or SMBG5365A/TR13 equivalent, key selection criteria include its DO-215AA gull-wing package, 110 mA maximum Zener current (IZM), 25 °C/W junction-to-lead thermal resistance, and RoHS-compliant matte-tin plating.
Technical Context
This device operates in reverse-biased breakdown mode to maintain stable voltage across varying load currents and temperatures. Its Zener voltage is specified at 36 V ±10% under 30 mA DC test current (IZT), with dynamic impedance measured at 1 kHz AC modulation (10% of IZT).
The SMBG5365A/TR13 features a moisture sensitivity level 1 rating per IPC/JEDEC J-STD-020B, eliminating dry-pack requirements. Thermal performance is defined by RθJL = 25 °C/W and RθJA = 90 °C/W on FR4 board with recommended footprint.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5365B | Axial-leaded T-18 package; identical electrical specs but larger footprint and manual assembly requirement | Used where through-hole mounting or prototyping with breadboards is preferred | Select when legacy board compatibility or hand-soldering is required; not suitable for high-density SMT layouts |
| SMBJ5365B | DO-214AA J-bend package; same VZ, IZT, and IZM, but higher RθJA (100 °C/W vs. 90 °C/W) | Preferred for designs using existing DO-214AA footprints or requiring tighter lead pitch | Choose when board layout uses DO-214AA land pattern; verify thermal margin due to reduced heatsinking efficiency |
Compared with SMBG5365A/TR13, 1N5365B requires PCB redesign for SMT transition, while SMBJ5365B offers footprint compatibility at the cost of slightly degraded thermal performance in ambient-convection environments.

FAQ
What is the Zener voltage tolerance for SMBG5365A/TR13?
The "A" suffix in SMBG5365A/TR13 denotes ±10% Zener voltage tolerance, meaning the actual breakdown voltage falls between 32.4 V and 39.6 V at 30 mA test current (IZT) and 25 °C. This tolerance is verified per Microsemi's T4-LDS-0246-1 specification and applies across the full operating temperature range of –65 °C to +150 °C.
Does SMBG5365A/TR13 require dry packing before SMT assembly?
No, SMBG5365A/TR13 does not require dry packing. It carries a moisture sensitivity level (MSL) 1 rating per IPC/JEDEC J-STD-020B, confirmed in the official Microsemi datasheet. This allows indefinite floor life and direct placement from tape-and-reel without baking or humidity-controlled storage.
What is the maximum continuous Zener current for SMBG5365A/TR13?
The maximum continuous Zener current (IZM) for SMBG5365A/TR13 is 110 mA, calculated per Note 3 in the datasheet using P = 5.0 W and VZM = 39.6 V (upper limit of ±10% tolerance). This value assumes TL < 25 °C and proper thermal management via the gull-wing leads.
How does the DO-215AA package of SMBG5365A/TR13 differ from DO-214AA?
The DO-215AA package used by SMBG5365A/TR13 features gull-wing leads optimized for visual solder inspection and high-yield reflow, whereas DO-214AA has J-bend leads. Dimensions differ: DO-215AA body width is 3.30–3.94 mm (C), versus DO-214AA's 3.56–4.06 mm; lead spacing (E) is 1.95–2.65 mm for DO-215AA, compared to 2.29–2.79 mm for DO-214AA.
Is SMBG5365A/TR13 RoHS compliant?
Yes, SMBG5365A/TR13 is RoHS compliant. The "TR13" suffix indicates tape-and-reel packaging with RoHS-compliant matte-tin plating on gull-wing terminals, as documented in Microsemi's T4-LDS-0246-1 datasheet and verified against JEDEC J-STD-020B standards.
