Product details
Overview
SMBG5364AE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 33 V, ±10% tolerance (A suffix), rated test current of 40 mA, maximum dynamic impedance of 10 Ω at IZT, and DO-215AA gull-wing package. It regulates voltage in power supply feedback loops and overvoltage protection circuits across industrial control and telecom power systems.
For engineers reviewing the SMBG5364AE3/TR13 datasheet, SMBG5364AE3/TR13 pinout, SMBG5364AE3/TR13 application, or SMBG5364AE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current capability (IZSM = 150 A), thermal resistance (RθJL = 25 °C/W), and RoHS-compliant matte-tin plating for lead-free assembly.
Technical Context
This device operates as a precision voltage reference in reverse-biased breakdown mode, maintaining stable regulation over 1.0 mA to 150 mA operating current range. Its low dynamic impedance (10 Ω) and minimal voltage drift versus temperature (−65 to +150 °C junction range) support tight regulation in feedback networks.
The DO-215AA gull-wing package enables visible solder joints and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity-no dry pack required. Thermal resistance junction-to-lead is 25 °C/W, enabling 5 W dissipation at TL < 25 °C with adequate heat sinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 33 V ±10% - defines regulated output voltage in shunt regulator applications |
| Test Current (IZT) | 40 mA - dc current at which VZ is specified; sets operating point for stable regulation |
| Dynamic Impedance (ZZT) | 10 Ω - small-signal ac impedance in breakdown; determines regulation stiffness under load transients |
| Max Surge Current (IZSM) | 150 A (8.3 ms half-sine) - peak non-repetitive current handling for transient suppression |
| Power Dissipation (PD) | 5.0 W @ TL < 25 °C - maximum continuous power with lead temperature control |
| Junction Temp Range | −65 to +150 °C - operational envelope for industrial and telecom environments |
| Reverse Leakage (IR) | 0.5 µA @ VR = 23.8 V - ensures low standby power loss in high-impedance bias networks |
Pinout & Package

| Gull-wing lead form | Visible solder joints enable automated optical inspection (AOI) and reliable process validation |
| High surge robustness | 150 A non-repetitive surge rating protects downstream circuitry from line transients and ESD events |
| Low dynamic impedance | 10 Ω at 40 mA ensures <0.4 V regulation deviation across 10–100 mA load variation |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5364B | Through-hole DO-41 package; identical VZ, IZT, ZZT, and IZSM specs | Requires PCB redesign for axial-leaded mounting; no AOI-compatible leads | Select when legacy through-hole assembly or manual repair is required |
| SMBG5364BE3/TR13 | Same DO-215AA package but ±5% tolerance (B suffix); tighter VZ spec, higher IZM (150 mA vs. 140 mA) | Better regulation accuracy in precision references; slightly higher cost | Select when ±5% VZ tolerance is needed for tighter feedback control |
Compared with SMBG5364AE3/TR13, 1N5364B requires board-level rework for mounting, while SMBG5364BE3/TR13 improves voltage accuracy at the expense of tighter tolerance-driven cost and reduced margin for VZ drift in wide-temperature designs.

FAQ
What is the Zener voltage tolerance for SMBG5364AE3/TR13?
The "A" suffix in SMBG5364AE3/TR13 indicates ±10% Zener voltage tolerance, meaning the measured VZ at 40 mA will fall between 29.7 V and 36.3 V. This tolerance is verified per JEDEC test methods and applies across the full operating temperature range of −65 to +150 °C. SMBG5364AE3/TR13 maintains this specification under standard reflow and aging conditions.
Does SMBG5364AE3/TR13 require dry packing before reflow soldering?
No, SMBG5364AE3/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it may be stored and processed without dry pack or baking. The DO-215AA package uses void-free epoxy meeting UL94V-0 and is qualified for standard lead-free reflow profiles up to 260 °C for 10 seconds. SMBG5364AE3/TR13 is fully compatible with automated SMT lines.
What is the maximum surge current rating for SMBG5364AE3/TR13?
SMBG5364AE3/TR13 is rated for 150 A maximum non-repetitive peak surge current (IZSM), defined as an 8.3 ms half-sine waveform. This rating is validated per Microsemi's qualification test plan and supports robust transient suppression in telecom and industrial power rails. SMBG5364AE3/TR13 sustains this surge without parameter shift or bond wire failure.
How does SMBG5364AE3/TR13 compare to the through-hole 1N5364B?
SMBG5364AE3/TR13 matches 1N5364B electrically-identical VZ, IZT, ZZT, IR, and IZSM-but uses DO-215AA gull-wing packaging instead of DO-41. SMBG5364AE3/TR13 enables surface-mount assembly, AOI compatibility, and higher board density. Both share the same Zener voltage temperature coefficient and long-term stability profile.
What is the thermal resistance junction-to-lead for SMBG5364AE3/TR13?
The thermal resistance junction-to-lead (RθJL) for SMBG5364AE3/TR13 is 25 °C/W, measured under standard test conditions per JESD51. This value enables 5.0 W continuous power dissipation when lead temperature (TL) is maintained below 25 °C-typically achieved using copper pour or thermal vias. SMBG5364AE3/TR13 thermal performance is documented in Microsemi T4-LDS-0246-1 Rev. 1.
