Product details
Overview
SMBG5382CE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 140 V, ±2% tolerance (C suffix), rated test current of 8.0 mA, maximum dynamic impedance of 230 Ω at IZT, and surge current capability of 1500 A (8.3 ms half-sine). It regulates voltage in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5382CE3/TR13 datasheet, SMBG5382CE3/TR13 pinout, SMBG5382CE3/TR13 application, or SMBG5382CE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (RθJL = 25 °C/W), surge robustness, RoHS-compliant matte-tin plating, and DO-215AA gull-wing package compatibility with automated SMT assembly.
Technical Context
This device operates in reverse breakdown to maintain stable reference voltage across wide current (IZK to IZM) and temperature (–65 to +150 °C) ranges. Its low dynamic impedance (230 Ω at 8.0 mA) ensures minimal voltage variation under load transients.
The DO-215AA gull-wing package enables visible solder joints and supports 5.0 W dissipation at TL < 25 °C, with thermal resistance junction-to-lead of 25 °C/W and junction-to-ambient of 90 °C/W on FR4 board - critical for compact power designs requiring reliable thermal management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 140 V ±2% at 8.0 mA - precise regulation point for high-voltage feedback networks. |
| Power Dissipation (PD) | 5.0 W at lead temperature < 25 °C - defines maximum continuous DC power handling with adequate heatsinking. |
| Dynamic Impedance (ZZT) | 230 Ω max at 8.0 mA - quantifies voltage stability under small-signal AC ripple superimposed on DC bias. |
| Surge Current (IZSM) | 1500 A (8.3 ms half-sine) - withstands transient overvoltage events without degradation. |
| Reverse Leakage (IR) | 0.5 µA max at 106 V - ensures negligible standby current in high-impedance sensing paths. |
| Junction Temperature Range | –65 to +150 °C - supports operation in industrial and automotive under-hood environments. |
| Thermal Resistance (RθJL) | 25 °C/W - enables accurate thermal modeling from lead temperature to junction for reliability prediction. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; banded end is anode when used as Zener (cathode connected to higher potential).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (banded end) | Reference node for Zener operation | Connected to lower-potential side of regulated circuit; polarity must be observed to avoid forward conduction. |
| Cathode (unbanded end) | Regulated output node | Connected to higher-potential side (e.g., feedback divider tap); maintains stable 140 V relative to anode under reverse bias. |
Key Features
| Feature | Design Value |
|---|---|
| RoHS-compliant matte-tin plating | Enables lead-free reflow soldering per JEDEC J-STD-020B Level 1 moisture sensitivity without dry pack. |
| Gull-wing lead form (DO-215AA) | Provides visual solder joint inspection and mechanical compliance for automated optical inspection (AOI) systems. |
| ±2% Zener voltage tolerance (C suffix) | Reduces need for post-assembly trimming in precision voltage references and feedback networks. |
| High surge current rating (1500 A) | Eliminates need for external TVS devices in moderate-energy transient suppression applications. |
| Low leakage (0.5 µA @ 106 V) | Maintains accuracy in high-resistance voltage dividers and battery-powered monitoring circuits. |
Applications
| Switch-Mode Power Supply Feedback | DC-DC Converter Overvoltage Clamp |
|---|---|
Use Scenario: Used in optocoupler-based feedback loop of isolated 48 V to 12 V flyback converter. IC Role / Device Role / Timing Role: Zener reference sets upper threshold for TL431-like error amplifier triggering. Use Value: 140 V rating allows safe clamping of reflected primary-side transients while maintaining tight regulation via ±2% VZ. |
Use Scenario: Placed across output capacitor of 24 V buck converter to prevent damage during load dump. IC Role / Device Role / Timing Role: Passive overvoltage clamp activated only during fault conditions exceeding 140 V. Use Value: 1500 A surge rating absorbs 100 mJ transients without failure, extending system MTBF. |
| Industrial Sensor Signal Conditioning | Programmable Logic Controller Input Protection |
Use Scenario: Biasing reference node in 4–20 mA transmitter front-end with 24 V loop supply. IC Role / Device Role / Timing Role: Stabilizes reference voltage for DAC output stage against supply fluctuations. Use Value: 230 Ω ZZT ensures <10 mV deviation across 1–10 mA load range, preserving 12-bit linearity. |
Use Scenario: Connected between field input terminal and ground in PLC analog input module. IC Role / Device Role / Timing Role: Primary overvoltage protector for 0–10 V sensor inputs exposed to ESD and inductive kick. Use Value: 0.5 µA leakage avoids loading high-impedance sources; gull-wing leads support IPC-A-610 Class 3 solder joint acceptance. |
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 electrical specs but no RoHS option; RθJA = 120 °C/W (higher thermal resistance). | Requires through-hole assembly and larger board area; unsuitable for high-density SMT layouts. | Select when legacy through-hole manufacturing or cost-sensitive non-RoHS designs dominate. |
| SMBJ5382B | DO-214AA J-bend package; same VZ, IZT, and PD, but RθJL = 30 °C/W and IZSM = 1200 A (lower surge margin). | Limited visibility for AOI; less robust for repetitive surge events in harsh environments. | Choose for space-constrained boards where J-bend footprint fits existing layout but surge margin is secondary. |
Compared with SMBG5382CE3/TR13, 1N5382B requires PCB redesign for through-hole mounting and offers inferior thermal performance, while SMBJ5382B sacrifices 20% surge current headroom and solder-joint inspectability - making SMBG5382CE3/TR13 optimal for new SMT designs demanding reliability, RoHS compliance, and visual process control.

FAQ
What is the Zener voltage tolerance of SMBG5382CE3/TR13?
The 'C' suffix in SMBG5382CE3/TR13 denotes ±2% Zener voltage tolerance at the specified test current of 8.0 mA. This tighter tolerance enables higher accuracy in voltage reference and feedback applications compared to ±5% (B suffix) or ±10% (A suffix) variants, reducing calibration overhead in production.
Does SMBG5382CE3/TR13 require dry packing before reflow soldering?
No, SMBG5382CE3/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it may be stored indefinitely at ambient conditions without dry pack. The DO-215AA package uses void-free epoxy meeting UL94V-0 and does not absorb significant moisture during standard handling.
What is the maximum surge current rating for SMBG5382CE3/TR13?
SMBG5382CE3/TR13 is rated for 1500 A peak non-repetitive surge current (IZSM) under an 8.3 ms half-sine waveform. This value is confirmed in the Electrical Characteristics table on page 3 of the Microsemi datasheet T4-LDS-0246-1 Rev. 1, and reflects its suitability for transient overvoltage suppression in industrial power systems.
How does the DO-215AA package of SMBG5382CE3/TR13 differ from DO-214AA?
The DO-215AA gull-wing package of SMBG5382CE3/TR13 provides visible solder joints for AOI, whereas DO-214AA uses J-bend leads that conceal the heel of the solder fillet. DO-215AA also achieves lower thermal resistance (RθJL = 25 °C/W vs. 30 °C/W for DO-214AA), improving power handling in thermally constrained layouts.
Is SMBG5382CE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5382CE3/TR13 features RoHS-compliant annealed matte-tin plating and is qualified for solder reflow up to 260 °C for 10 seconds (per MIL-STD-750 Method 2026). Its moisture level 1 classification eliminates pre-bake requirements, supporting standard Pb-free reflow profiles including JEDEC J-STD-020D.
