Product details
Overview
SMBG5382AE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 140 V, ±10% tolerance (A suffix), and maximum Zener current IZM of 34 mA at TL < 25 °C. It uses DO-215AA gull-wing package, delivers dynamic impedance of 230 Ω at 10 mA test current, and operates across –65 °C to +150 °C junction temperature range. It serves as precision voltage reference and overvoltage clamp in DC power supply regulation circuits.
For engineers reviewing the SMBG5382AE3/TR13 datasheet, SMBG5382AE3/TR13 pinout, SMBG5382AE3/TR13 application, or SMBG5382AE3/TR13 equivalent, key selection criteria include its 140 V Zener voltage, 5 W power rating at lead temperature < 25 °C, ±10% voltage tolerance, DO-215AA gull-wing thermal performance (RθJL = 25 °C/W), and RoHS-compliant matte-tin plating.
Technical Context
This device functions as a silicon planar Zener diode operating in reverse-biased breakdown region, delivering stable reference voltage under controlled regulator current (IZT = 8.0 mA). Its design supports high-surge capability (IZSM = 1500 A for 8.3 ms half-sine) and low leakage (IR ≤ 0.5 µA at VR = 106 V).
The DO-215AA gull-wing package enables visible solder joints and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity without dry pack. Thermal resistance from junction-to-lead is 25 °C/W, enabling effective heat conduction through PCB leads when mounted per recommended footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 140 V ±10% - Stable regulation point at IZT = 8.0 mA; high-voltage clamping for 120 VAC-derived supplies. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - Requires thermal management via lead conduction; derates to 1.38 W at TA = 25 °C on FR4. |
| Dynamic Impedance (ZZT) | 230 Ω @ 8.0 mA - Low AC impedance ensures minimal voltage variation under load transients. |
| Max Reverse Current (IR) | ≤ 0.5 µA @ VR = 106 V - Ensures negligible leakage in high-impedance bias networks. |
| Junction Temperature Range | –65 °C to +150 °C - Suitable for industrial and automotive under-hood environments. |
| Thermal Resistance (RθJL) | 25 °C/W - Enables efficient heat transfer to PCB copper; critical for sustained 5 W operation. |
| Surge Current (IZSM) | 1500 A (8.3 ms half-sine) - Withstands lightning-induced or inductive-switching transients. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; banded end must be held positive relative to anode during operation. Leads are RoHS-compliant annealed matte-tin plated and solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference/Return node | Connected to system ground or lower-potential rail; carries full Zener current during regulation. |
| Cathode | Regulated output node | Banded terminal; held at stable 140 V above anode; interfaces directly with feedback or clamp circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5382B equivalent | Identical electrical specs and testing to legacy axial 1N5382B - enables drop-in replacement in legacy designs. |
| Level 1 moisture sensitivity | No dry pack required - simplifies SMT handling and eliminates bake-out steps before reflow. |
| Gull-wing lead form | Visible solder joints - enables automated optical inspection (AOI) and improves process yield verification. |
| High surge robustness | 1500 A non-repetitive surge rating - protects downstream circuitry from ESD and inductive kick events. |
| RoHS-compliant plating | e3 suffix denotes matte-tin finish - satisfies environmental compliance without sacrificing solderability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5382B | Axial-leaded T-18 package; identical VZ, IZT, ZZT, and IR specs; no RoHS compliance (Sn/Pb plating). | Requires through-hole assembly; unsuitable for high-density SMT layouts. | Select when legacy through-hole manufacturing or cost-sensitive non-RoHS projects demand exact JEDEC form factor. |
| SMBJ5382B | DO-214AA J-bend package; same VZ, IZT, and electrical specs; RθJA = 90 °C/W vs. SMBG's 25 °C/W junction-to-lead path. | Limited thermal performance in high-power continuous operation due to higher thermal resistance to ambient. | Select when board space permits J-bend footprint and thermal load remains below 1.38 W at ambient conditions. |
Compared with SMBG5382AE3/TR13, 1N5382B requires through-hole assembly and lacks RoHS compliance, while SMBJ5382B offers identical Zener characteristics but inferior thermal conduction-making SMBG5382AE3/TR13 optimal for high-reliability, high-power SMT applications demanding visible solder joints and lead-based heat sinking.

FAQ
What is the Zener voltage tolerance of SMBG5382AE3/TR13?
The 'A' suffix in SMBG5382AE3/TR13 indicates a ±10% Zener voltage tolerance. At 25 °C, its nominal VZ is 140 V, meaning the actual measured breakdown voltage falls between 126 V and 154 V under specified test conditions (IZT = 8.0 mA). This tolerance is confirmed in the Electrical Characteristics table on page 3 of the Microsemi datasheet T4-LDS-0246-1.
Does SMBG5382AE3/TR13 require dry packing before reflow soldering?
No, SMBG5382AE3/TR13 does not require dry packing. Its moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1, meaning it can be stored indefinitely at standard ambient conditions (≤30 °C / 60% RH) without baking. This is explicitly stated in the "MECHANICAL and PACKAGING" section on page 2 of the Microsemi datasheet.
What is the maximum surge current rating for SMBG5382AE3/TR13?
SMBG5382AE3/TR13 has a maximum non-repetitive Zener surge current (IZSM) of 1500 A for an 8.3 ms half-sine waveform, as specified in the Electrical Characteristics table on page 3 of the Microsemi datasheet. This rating applies only to single-event transients and must not be exceeded repeatedly without thermal recovery time.
How does the thermal resistance of SMBG5382AE3/TR13 compare between junction-to-lead and junction-to-ambient?
SMBG5382AE3/TR13 has RθJL = 25 °C/W and RθJA = 90 °C/W (on FR4 with recommended footprint). The 25 °C/W junction-to-lead path enables effective heat conduction through PCB copper traces, while the higher RθJA reflects limited natural convection cooling-confirming that lead conduction is the primary thermal path for sustained 5 W operation.
Is SMBG5382AE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5382AE3/TR13 is qualified for lead-free reflow with a peak solder temperature of 260 °C for 10 seconds, as documented in the "MAXIMUM RATINGS" table on page 1. Its RoHS-compliant matte-tin (e3) plating ensures reliable wetting and intermetallic formation under standard Pb-free reflow profiles (e.g., JEDEC J-STD-020).
