Product details
Overview
SMBG5364CE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 33 V, ±2% tolerance (C suffix), rated test current of 40 mA, dynamic impedance of 10 Ω at IZT, and maximum regulator current of 150 mA - used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5364CE3/TR13 datasheet, SMBG5364CE3/TR13 pinout, SMBG5364CE3/TR13 application, or SMBG5364CE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (RθJL = 25 °C/W), surge current rating (IZSM = 150 A), and RoHS-compliant matte-tin plating for lead-free assembly.
Technical Context
This device operates in reverse-biased breakdown mode to maintain stable reference voltage across wide current (IZK to IZM) and temperature (-65 °C to +150 °C) ranges. Its DO-215AA gull-wing package enables visible solder joints and supports high-density PCB layouts.
It exhibits low dynamic impedance (10 Ω at 40 mA) and minimal voltage drift versus current, meeting JEDEC 1N5333–1N5388B electrical equivalence requirements. The cathode band marking defines polarity, and operation requires the banded end to be positive relative to the anode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 33 V ±2% at 40 mA - ensures tight regulation tolerance for feedback references in SMPS designs. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - supports robust transient handling with adequate heat sinking on FR4 board. |
| Dynamic Impedance (ZZT) | 10 Ω at IZT = 40 mA - minimizes output voltage variation under load current changes. |
| Max Regulator Current (IZM) | 150 mA - defines safe DC operating limit before thermal runaway at rated power. |
| Surge Current (IZSM) | 150 A (8.3 ms half-sine) - withstands high-energy transients in industrial power rails. |
| Junction-to-Lead Thermal Resistance | 25 °C/W - enables efficient heat transfer to PCB copper, critical for sustained 5 W operation. |
| Reverse Leakage (IR) | <0.5 µA at 25.1 V - guarantees low standby power loss in precision bias networks. |
Pinout & Package
DO-215AA gull-wing surface-mount package with two terminals: anode and cathode. Cathode identified by molded 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 rail (e.g., ground or return path) during Zener operation. |
| Cathode | Current exit terminal in forward bias; regulated output node in reverse bias | Connected to voltage source or feedback node; marked by band; must be at higher potential than anode. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N53xxB Equivalent | Identical electrical specs and test methods to legacy through-hole 1N5364B - simplifies drop-in replacement in upgraded SMT designs. |
| RoHS Compliant Matte-Tin Plating | e3 suffix confirms annealed matte-tin finish per MIL-STD-750 - ensures reliable solderability and compatibility with Pb-free reflow profiles. |
| Moisture Sensitivity Level 1 | No dry pack required per IPC/JEDEC J-STD-020B - eliminates baking step and reduces handling cost in production. |
| Gull-Wing Lead Geometry | DO-215AA footprint enables visual solder joint inspection and improves mechanical reliability under thermal cycling. |
| High Surge Withstand | 150 A non-repetitive surge rating (8.3 ms) - protects downstream circuitry from lightning-induced or inductive-switching transients. |
Applications
| Switch-Mode Power Supply Feedback | Overvoltage Clamp Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5364BRLG | Axial-leaded T-18 package; identical VZ, IZT, and tolerance but higher RθJA (120 °C/W vs. 90 °C/W). | Requires through-hole mounting and larger board area; unsuitable for high-density SMT assemblies. | Select when legacy through-hole design reuse or manual prototyping is prioritized over space and thermal performance. |
| SMBJ5364CE3/TR13 | DO-214AA J-bend package; same VZ, tolerance, and power rating but 30% higher RθJA (117 °C/W) due to smaller thermal pad area. | Lower thermal efficiency limits continuous power in compact layouts; less suitable for sustained 5 W operation. | Choose only if DO-214AA footprint is already standardized in the design and thermal derating is acceptable. |
Compared with SMBG5364CE3/TR13, the 1N5364BRLG offers identical regulation performance but sacrifices SMT manufacturability and thermal efficiency, while the SMBJ5364CE3/TR13 retains surface-mount compatibility at the cost of reduced thermal margin under full-load conditions.

FAQ
What is the Zener voltage tolerance of SMBG5364CE3/TR13?
The SMBG5364CE3/TR13 has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in the part number. This means its nominal 33 V Zener voltage is guaranteed between 32.34 V and 33.66 V at the specified test current of 40 mA and junction temperature of 25 °C, enabling precise voltage reference applications.
Does SMBG5364CE3/TR13 require moisture preconditioning before reflow?
No, SMBG5364CE3/TR13 has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it is not humidity-sensitive and does not require dry packing or baking prior to reflow soldering - reducing manufacturing overhead and eliminating moisture-related popcorning risk.
What is the maximum surge current rating for SMBG5364CE3/TR13?
The SMBG5364CE3/TR13 is rated for a non-repetitive peak Zener surge current (IZSM) of 150 A, defined for an 8.3 ms half-sine waveform. This rating allows the device to safely clamp high-energy transients in industrial power rails without permanent degradation when properly heatsinked.
How does the DO-215AA package of SMBG5364CE3/TR13 differ from DO-214AA?
The DO-215AA gull-wing package of SMBG5364CE3/TR13 provides visible solder joints and lower thermal resistance (RθJL = 25 °C/W) compared to the DO-214AA J-bend variant (SMBJ5364CE3/TR13), which has higher RθJA (117 °C/W). Gull-wing geometry also improves mechanical reliability under thermal cycling stress.
Is SMBG5364CE3/TR13 compatible with lead-free reflow processes?
Yes, SMBG5364CE3/TR13 carries the "e3" suffix confirming RoHS-compliant annealed matte-tin plating, qualified for standard Pb-free reflow profiles up to 260 °C for 10 seconds. Its thermosetting epoxy body meets UL94V-0 flammability rating and withstands repeated thermal excursions without delamination.
