Product details
Overview
SMBG5382BE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 140 V, ±5% tolerance (B suffix), 8.0 mA test current (IZT), 230 Ω dynamic impedance (ZZT), and 1.2 A maximum surge current (IZSM). It regulates voltage in power supply feedback loops and overvoltage protection circuits across industrial and telecom power systems.
For engineers reviewing the SMBG5382BE3/TR13 datasheet, SMBG5382BE3/TR13 pinout, SMBG5382BE3/TR13 application, or SMBG5382BE3/TR13 equivalent, key selection criteria include its 140 V regulation point, DO-215AA gull-wing package thermal performance (RθJA = 90 °C/W on FR4), 1.2 A non-repetitive surge rating, and RoHS-compliant matte-tin plating.
Technical Context
This device operates as a precision voltage reference in reverse-biased breakdown mode, maintaining stable regulation across 1.0–100 mA operating current range with minimal voltage drift versus temperature (−65 to +150 °C junction range). Its 230 Ω dynamic impedance at 8.0 mA ensures predictable clamping behavior under transient load shifts.
The SMBG5382BE3/TR13 uses a void-free UL94V-0 epoxy body and gull-wing leads compatible with standard reflow profiles (260 °C for 10 s). Cathode polarity is marked by a band; operation requires the banded end to be positive relative to the anode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 140 V ±5% at 8.0 mA - defines precise clamping threshold for overvoltage protection |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - supports high-energy transient suppression with adequate heatsinking |
| Dynamic Impedance (ZZT) | 230 Ω at IZT = 8.0 mA - determines regulation stiffness and output voltage variation under load changes |
| Max Surge Current (IZSM) | 1.2 A (8.3 ms half-sine) - enables robust handling of lightning-induced or switching transients |
| Thermal Resistance (RθJA) | 90 °C/W on FR4 (1 oz Cu) - sets maximum ambient temperature limit for continuous 5 W operation |
| Reverse Leakage (IR) | 0.5 µA at VR = 106 V - ensures low standby power loss in high-impedance bias networks |
| Junction Temperature Range | −65 to +150 °C - supports deployment in extended-temperature industrial and outdoor environments |
Pinout & Package
Package: DO-215AA gull-wing surface-mount package (JEDEC standard), moisture sensitivity level 1 (no dry pack required), 0.1 g weight, UL94V-0 epoxy body, cathode indicated by band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node in Zener regulator configuration | Connected to system ground or lower-potential rail; reverse-biased during regulation |
| Cathode | Regulated output node | Banded terminal; held at stable 140 V above anode when reverse current ≥8.0 mA |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5382B equivalence | Identical electrical specs and test methods to legacy through-hole 1N5382B, enabling drop-in replacement in upgraded layouts |
| Gull-wing lead form | Enables visual solder joint inspection and reliable reflow attachment on high-density PCBs |
| RoHS-compliant matte-tin plating | Meets IPC-J-STD-020B Level 1 moisture sensitivity without dry-pack requirement |
| High surge current rating | 1.2 A non-repetitive peak withstand capability supports IEC 61000-4-5 Level 4 surge immunity designs |
| Stable voltage vs. current | Low dynamic impedance (230 Ω) and tight 5% tolerance minimize regulation error across 1–100 mA operating range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5382B | Same 140 V ±5%, 5 W rating, but axial T-18 package with higher RθJA (120 °C/W) and no RoHS compliance. | Requires through-hole assembly; unsuitable for automated SMT lines or high-density boards. | Select only for legacy repair or prototyping where footprint compatibility is secondary to cost. |
| SMBJ5382B | Identical electrical specs but DO-214AA J-bend package; RθJA = 100 °C/W on same FR4 layout, 0.2 g weight. | Lacks gull-wing visibility; slightly reduced thermal performance limits continuous power at elevated ambient. | Prefer when existing J-bend footprint exists or when board space constraints favor shorter lead span. |
Compared with SMBG5382BE3/TR13, 1N5382B trades SMT manufacturability for through-hole serviceability, while SMBJ5382B sacrifices thermal margin and visual inspection capability for compactness-neither offers pin-compatible replacement without layout revision.

FAQ
What is the Zener voltage tolerance for SMBG5382BE3/TR13?
The "B" suffix in SMBG5382BE3/TR13 indicates a ±5% Zener voltage tolerance, meaning its actual breakdown voltage falls between 133 V and 147 V when measured at 8.0 mA and 25 °C. This tolerance is verified per JEDEC test methods and applies across the full −65 to +150 °C junction temperature range.
Does SMBG5382BE3/TR13 require dry packing before reflow soldering?
No, SMBG5382BE3/TR13 has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ≤30 °C/60% RH without dry packing. The void-free UL94V-0 epoxy body and matte-tin plating eliminate popcorning risk during standard 260 °C/10 s reflow profiles.
What is the maximum continuous Zener current for SMBG5382BE3/TR13 at 70 °C ambient?
At TA = 70 °C on FR4 with 1 oz Cu, SMBG5382BE3/TR13's derated power is 2.78 W (per Figure 1 derating curve), yielding a maximum continuous Zener current of 19.9 mA (2.78 W ÷ 140 V). Exceeding this risks thermal runaway due to RθJA = 90 °C/W limiting junction temperature rise.
Can SMBG5382BE3/TR13 replace 1N5382B in existing designs?
SMBG5382BE3/TR13 matches 1N5382B electrically (same VZ, IZT, ZZT, IZM), but its DO-215AA gull-wing footprint differs from 1N5382B's axial T-18 leads. Direct replacement requires PCB redesign; however, it serves as a validated functional upgrade for new SMT-based revisions targeting higher reliability and RoHS compliance.
What surge waveform does the 1.2 A IZSM rating for SMBG5382BE3/TR13 correspond to?
The 1.2 A maximum surge current (IZSM) for SMBG5382BE3/TR13 is specified for a single non-repetitive 8.3 ms half-sine wave, per Note 4 on page 3 of the datasheet. This aligns with IEC 61000-4-5 Combination Wave Generator (CWG) open-circuit voltage surge testing protocols used in telecom and industrial equipment certification.
