Product details

Overview

SMBG5364C/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 33 V, ±2% tolerance (C suffix), and DO-215AA gull-wing package. It regulates voltage across wide current and temperature ranges, supports surge currents up to 150 A (8.3 ms half-sine), and operates from –65 °C to +150 °C junction temperature - used in power supply overvoltage protection and reference circuits.

For engineers reviewing the SMBG5364C/TR13 datasheet, SMBG5364C/TR13 pinout, SMBG5364C/TR13 application, or SMBG5364C/TR13 equivalent, key selection criteria include Zener voltage tolerance (±2%), thermal resistance (R_θJL = 25 °C/W), maximum regulator current (IZM = 150 mA), and RoHS-compliant matte-tin plating.

Technical Context

This device functions as a precision voltage reference and overvoltage clamp in DC power rails. Its low dynamic impedance (Z_ZT = 10 Ω at I_ZT = 40 mA) ensures stable regulation under varying load conditions, while its moisture sensitivity level 1 rating eliminates dry-pack requirements.

The SMBG5364C/TR13 uses a void-free thermosetting epoxy case (UL94V-0), gull-wing leads for visible solder joints, and cathode polarity marked by a band. It meets JEDEC 1N5333–1N5388B electrical equivalence and withstands 260 °C soldering for 10 s.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	33 V ±2% at I_ZT = 40 mA - defines precise clamping threshold for 3.3 V–33 V rail protection.
Power Dissipation (P_D)	5.0 W at T_L < 25 °C - requires thermal management on FR4 board to sustain full rating.
Dynamic Impedance (Z_ZT)	10 Ω at I_ZT = 40 mA - minimizes output voltage variation under load transients.
Max Regulator Current (I_ZM)	150 mA - sets upper limit for continuous Zener bias without exceeding P_D.
Surge Current (I_ZSM)	150 A (8.3 ms half-sine) - handles transient overvoltage events like ESD or inductive kickback.
Junction Temperature Range	–65 °C to +150 °C - enables operation in automotive under-hood and industrial control environments.
Thermal Resistance (R_θJL)	25 °C/W - allows direct thermal path to PCB copper for efficient heat transfer.

Pinout & Package

DO-215AA gull-wing surface-mount package with two terminals: anode and cathode. Cathode identified by a band; device operated with banded end positive relative to anode.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Current entry terminal in forward bias; reference node in reverse-bias regulation	Connected to lower-potential side of protected circuit; forms return path during clamping.
Cathode	Current exit terminal in forward bias; Zener breakdown terminal in reverse bias	Banded end; connected to higher-potential rail; establishes regulated voltage at this node.

Key Features

Feature	Design Value
JEDEC 1N53xxB Equivalent	Identical electrical specs and test methods to legacy through-hole 1N5364B - simplifies redesign from axial to SMT.
RoHS Compliant Matte-Tin Plating	e3 marking confirms lead-free finish compliant with IPC/JEDEC J-STD-020B Level 1 - no dry pack needed for assembly.
Low Dynamic Impedance	Z_ZT = 10 Ω at 40 mA - maintains tight voltage regulation across 10–150 mA operating range.
High Surge Withstand	150 A non-repetitive surge (8.3 ms) - protects downstream ICs from lightning-induced or switching transients.
Gull-Wing Lead Geometry	DO-215AA footprint with visible solder joints - enables AOI inspection and improves reworkability vs. J-bend packages.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N5364B	Axial-leaded T-18 package; identical V_Z, tolerance, and I_ZM; R_θJA = 120 °C/W vs. 90 °C/W for SMBG.	Requires through-hole mounting; unsuitable for high-density SMT layouts.	Select when legacy board design mandates axial components or manual prototyping is preferred.
SMBJ5364C	DO-214AA J-bend package; same V_Z, tolerance, and power rating; R_θJL = 30 °C/W vs. 25 °C/W for SMBG.	Lower thermal performance; less visible solder joint; incompatible footprint.	Choose only if existing layout uses DO-214AA or space constraints favor J-bend geometry.

Compared with SMBG5364C/TR13, 1N5364B offers identical regulation but inferior thermal dissipation and board area efficiency, while SMBJ5364C sacrifices thermal advantage and solder inspection capability for footprint compatibility with older SMBJ footprints.

FAQ

What is the Zener voltage tolerance for SMBG5364C/TR13?

The "C" suffix in SMBG5364C/TR13 specifies a ±2% Zener voltage tolerance at I_ZT = 40 mA and T_L = 25 °C. This yields a guaranteed V_Z range of 32.34 V to 33.66 V, enabling tighter regulation than ±5% (B) or ±10% (A) variants in precision reference applications.

Does SMBG5364C/TR13 require dry packing before reflow soldering?

No. SMBG5364C/TR13 has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it is not moisture-sensitive and does not require dry packing or baking prior to reflow. The void-free UL94V-0 epoxy encapsulation provides inherent moisture resistance.

What is the maximum surge current rating for SMBG5364C/TR13?

SMBG5364C/TR13 is rated for a non-repetitive peak surge current (I_ZSM) of 150 A, defined as a single 8.3 ms half-sine waveform. This rating applies under specified test conditions and supports robust protection against load dump, ESD, and inductive switching transients in automotive and industrial systems.

How does the thermal resistance of SMBG5364C/TR13 compare between junction-to-lead and junction-to-ambient?

SMBG5364C/TR13 has R_θJL = 25 °C/W and R_θJA = 90 °C/W (on FR4 with recommended footprint). The 3.6× lower junction-to-lead resistance indicates that heat is most efficiently removed via the leads into PCB copper, making thermal pad design under the leads critical for sustaining 5 W operation.

Is SMBG5364C/TR13 compatible with lead-free reflow profiles?

Yes. SMBG5364C/TR13 features RoHS-compliant annealed matte-tin plating (e3 marking) and is qualified for solder reflow at 260 °C for 10 seconds, fully supporting standard lead-free reflow profiles such as IPC/JEDEC J-STD-020D.
