Product details
Overview
SMBG5365AE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 36 V, ±10% tolerance (A suffix), and DO-215AA gull-wing package. It regulates voltage across wide current and temperature ranges, supports surge currents up to 160 A (8.3 ms half-sine), and is rated for junction temperatures from –65 °C to +150 °C. It is used in overvoltage protection and precision reference circuits in industrial power supplies.
For engineers reviewing the SMBG5365AE3/TR13 datasheet, SMBG5365AE3/TR13 pinout, SMBG5365AE3/TR13 application, or SMBG5365AE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (RθJL = 25 °C/W), maximum regulator current (IZM = 160 mA), surge capability (IZSM = 160 A), and RoHS-compliant matte-tin plating (e3 suffix).
Technical Context
This device operates in reverse breakdown to maintain stable voltage under varying load and temperature conditions. Its dynamic impedance (ZZT) is 11 Ω at IZT = 30 mA, and knee impedance (ZZK) is 20 Ω at 1.0 mA - indicating low voltage drift near regulation threshold.
The SMBG5365AE3/TR13 uses a void-free thermosetting epoxy case (UL94V-0), features cathode band polarity marking, and is moisture-sensitive Level 1 per J-STD-020B - eliminating dry-pack requirements. It is rated for 5.0 W at TL < 25 °C, derating linearly above that point.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 36 V ±10% at IZT = 30 mA - defines primary regulation point with controlled tolerance for reference stability. |
| Maximum Power Dissipation (PD) | 5.0 W at lead temperature < 25 °C - sets absolute thermal limit before derating; requires heatsinking for sustained operation. |
| Dynamic Impedance (ZZT) | 11 Ω at IZT = 30 mA - determines small-signal voltage variation under AC ripple or transient load changes. |
| Maximum Regulator Current (IZM) | 160 mA - maximum DC current sustainable without exceeding PD, critical for sizing series resistors in shunt regulators. |
| Surge Current (IZSM) | 160 A (8.3 ms half-sine) - enables transient overvoltage clamping in surge protection circuits without failure. |
| Junction-to-Lead Thermal Resistance (RθJL) | 25 °C/W - quantifies thermal path efficiency from die to PCB lead; informs layout copper area and thermal pad design. |
| Reverse Leakage (IR) | 0.5 µA at VR = 25.9 V - ensures minimal standby current in high-impedance 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; common reference node in shunt regulator configuration. | Connected to system ground or lower-potential rail; forms return path for Zener current during regulation. |
| Cathode | Current exit terminal in forward bias; regulated output node in reverse-bias Zener operation. | Connected to protected node or reference input; maintains stable 36 V potential when reverse-biased above VZ. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5365B equivalent | Identical electrical specs and test methods - enables drop-in replacement in legacy designs qualified to MIL-STD-750. |
| RoHS-compliant matte-tin plating (e3) | Lead-free solder compatibility and corrosion resistance - meets IPC-J-STD-006B and eliminates Sn/Pb handling concerns. |
| Gull-wing leads (DO-215AA) | Visible solder joints and mechanical strain relief - improves optical inspection yield and reduces solder joint fatigue in thermal cycling. |
| Moisture Sensitivity Level 1 | No dry-pack or baking required before reflow - simplifies SMT line logistics and avoids moisture-induced popcorning. |
| High surge current rating (160 A) | Withstands IEC 61000-4-5 Level 4 surges - suitable for front-end protection in industrial AC/DC converters and telecom power interfaces. |
Applications

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 (36 V), ±5% tolerance (B suffix), Sn/Pb plating - no RoHS compliance. | Legacy industrial designs requiring Pb-based soldering; not suitable for new RoHS-compliant production. | Select only if Sn/Pb assembly process is mandated and moisture sensitivity handling is acceptable. |
| SMBJ5365B | Same VZ and tolerance, but DO-214AA (J-bend) package - RθJA = 90 °C/W vs. 25 °C/W (RθJL) for SMBG5365AE3/TR13. | Lower-power or space-constrained layouts where gull-wing visibility is unnecessary and thermal performance is less critical. | Choose when board-level thermal management is limited and peak surge duty is infrequent. |
Compared with 1N5365B and SMBJ5365B, SMBG5365AE3/TR13 offers RoHS compliance, superior thermal conduction via gull-wing leads (RθJL = 25 °C/W), and visible solder joints - making it optimal for high-reliability, thermally demanding, and modern SMT production environments.

FAQ
What is the Zener voltage tolerance for SMBG5365AE3/TR13?
The SMBG5365AE3/TR13 has a Zener voltage tolerance of ±10%, indicated by the "A" suffix in the part number. This means its nominal 36 V Zener voltage is specified between 32.4 V and 39.6 V at IZT = 30 mA and TL = 25 °C. The tolerance directly impacts regulation accuracy in reference and protection circuits - tighter tolerances require B or C suffix variants.
Does SMBG5365AE3/TR13 require dry packing before reflow soldering?
No, SMBG5365AE3/TR13 does not require dry packing. It is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it can be stored indefinitely at ≤30 °C/60% RH without baking. This eliminates pre-reflow baking steps and reduces risk of popcorning during reflow - a key advantage for high-volume SMT lines.
What is the maximum continuous Zener current for SMBG5365AE3/TR13?
The maximum continuous Zener current (IZM) for SMBG5365AE3/TR13 is 160 mA at lead temperature < 25 °C. This value is derived from PD = 5.0 W and VZM = 39.6 V (upper limit of ±10% tolerance). Exceeding this current without adequate thermal management risks permanent degradation due to junction overheating.
How does the DO-215AA package of SMBG5365AE3/TR13 improve thermal performance?
The DO-215AA gull-wing package of SMBG5365AE3/TR13 provides a low thermal resistance path from junction to lead (RθJL = 25 °C/W), significantly better than typical DO-214AA alternatives (RθJA ≈ 90 °C/W). This allows more efficient heat transfer to the PCB copper, enabling higher sustained power dissipation without external heatsinks in compact industrial layouts.
Is SMBG5365AE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5365AE3/TR13 is fully compatible with lead-free reflow profiles. Its e3 suffix denotes RoHS-compliant annealed matte-tin plating, rated for solder temperatures up to 260 °C for 10 seconds. The device meets J-STD-020D moisture sensitivity requirements and withstands standard SAC305 peak reflow temperatures (245–260 °C) without parametric shift or delamination.
