Product details
Overview
SMBG5365BE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 36 V, ±5% tolerance (B suffix), 30 mA test current (IZT), 11 Ω dynamic impedance (ZZT), and DO-215AA gull-wing package. It regulates voltage in power supply feedback loops, overvoltage protection circuits, and reference voltage generation for industrial power converters.
For engineers reviewing the SMBG5365BE3/TR13 datasheet, SMBG5365BE3/TR13 pinout, SMBG5365BE3/TR13 application, or SMBG5365BE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current rating (160 A), thermal resistance (25 °C/W junction-to-lead), and RoHS-compliant matte-tin plating for lead-free assembly.
Technical Context
This device operates in reverse breakdown to maintain stable voltage across wide current (1–30 mA) and temperature (−65 to +150 °C) ranges. Its low dynamic impedance (11 Ω at 30 mA) ensures minimal voltage variation under load transients.
The DO-215AA gull-wing package provides 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 reliable 5 W operation with adequate PCB copper area.
Key Specifications

|---|---|
| Zener Voltage (VZ) | 36 V ±5% at 30 mA - defines precise regulation point for feedback networks |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - supports high-energy clamping without heatsink in compact layouts |
| Dynamic Impedance (ZZT) | 11 Ω at IZT = 30 mA - ensures <0.33 V deviation over ±10 mA load change |
| Max Surge Current (IZSM) | 160 A (8.3 ms half-sine) - withstands IEC 61000-4-5 Level 4 surges |
| Junction Temp Range | −65 to +150 °C - qualified for automotive under-hood and industrial motor drive environments |
| Thermal Resistance RθJL | 25 °C/W - enables direct thermal path to PCB copper for efficient heat transfer |
| Reverse Leakage (IR) | 0.5 µA at VR = 25.9 V - negligible error contribution in precision reference circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5365B | Same VZ, IZT, ZZT, and PD; axial T-18 package instead of DO-215AA | Requires through-hole mounting; unsuitable for high-density SMT boards | Select when legacy through-hole assembly or manual prototyping is used |
| SMBJ5365B | Identical specs but in DO-214AA (J-bend) package; same RoHS compliance | Different footprint and thermal path - RθJA = 90 °C/W vs. 25 °C/W junction-to-lead | Select when existing J-bend layout exists or higher ambient thermal resistance is acceptable |
Compared with SMBG5365BE3/TR13, 1N5365B requires PCB redesign for through-hole mounting, while SMBJ5365B offers identical electrical performance but reduced thermal efficiency due to higher junction-to-ambient resistance - SMBG5365BE3/TR13 delivers optimal power density and manufacturability for new SMT designs.

FAQ
What is the Zener voltage tolerance and test current for SMBG5365BE3/TR13?
The SMBG5365BE3/TR13 has a Zener voltage of 36 V with ±5% tolerance (denoted by 'B' suffix) and is tested at 30 mA (IZT). This tolerance ensures predictable regulation in feedback networks, and the 30 mA test point aligns with typical operating currents in switch-mode power supply references. The SMBG5365BE3/TR13 maintains this specification across −65 to +150 °C junction temperature.
Does SMBG5365BE3/TR13 require dry packing before reflow soldering?
No, SMBG5365BE3/TR13 has IPC/JEDEC J-STD-020B Level 1 moisture sensitivity - no dry pack or baking is required prior to reflow. Its void-free epoxy body and RoHS-compliant matte-tin plating support standard lead-free reflow profiles up to 260 °C for 10 seconds. This eliminates process steps and reduces risk of tombstoning in high-volume SMT lines using SMBG5365BE3/TR13.
What is the maximum surge current rating for SMBG5365BE3/TR13?
The SMBG5365BE3/TR13 is rated for 160 A maximum non-repetitive surge current (IZSM) using an 8.3 ms half-sine waveform. This rating enables robust protection against IEC 61000-4-5 Level 4 surges in industrial control inputs. The DO-215AA package's low RθJL (25 °C/W) helps dissipate surge energy rapidly into the PCB, making SMBG5365BE3/TR13 suitable for harsh electromagnetic environments.
How does SMBG5365BE3/TR13 compare to the axial 1N5365B in terms of electrical performance?
SMBG5365BE3/TR13 matches the 1N5365B exactly in Zener voltage (36 V ±5%), dynamic impedance (11 Ω), power rating (5 W), and leakage current (0.5 µA at 25.9 V). The only differences are mechanical: SMBG5365BE3/TR13 uses DO-215AA gull-wing packaging for SMT, while 1N5365B uses axial T-18. Electrical behavior of SMBG5365BE3/TR13 is functionally identical in circuit simulation and bench validation.
What is the thermal resistance from junction to ambient for SMBG5365BE3/TR13 on FR4?
When mounted on FR4 with 1 oz copper and the recommended footprint, SMBG5365BE3/TR13 has a junction-to-ambient thermal resistance (RθJA) of 90 °C/W. However, its junction-to-lead resistance (RθJL) is 25 °C/W - indicating superior heat transfer when thermal pads connect directly to internal copper planes. For continuous 5 W operation, SMBG5365BE3/TR13 requires ≥1 in² of 1 oz copper pour per side, per Microsemi's layout guidelines.
