Product details
Overview
SMBG5.0-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for primary overvoltage protection of DC power rails and signal lines. It features 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 µs), <9.2 V clamping voltage at 65.2 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMBG5.0-E3/52 datasheet, SMBG5.0-E3/52 pinout, SMBG5.0-E3/52 application, or SMBG5.0-E3/52 equivalent, this device is selected for robust ESD and surge protection in low-voltage automotive ECUs, industrial sensor interfaces, and 5 V USB power rail conditioning where fast response (<1 ns), low clamping ratio, and RoHS-compliant matte tin terminations are required.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: under normal bias it presents <800 µA reverse leakage at 5.0 V; during transients exceeding VBR, it avalanches to clamp energy within its 600 W rating while maintaining sub-10 V clamping up to 65.2 A. Its glass-passivated junction ensures stable breakdown and low dynamic impedance.
Thermal design relies on RθJA = 100 °C/W (on 0.2" × 0.2" copper pads) and RθJL = 20 °C/W, enabling operation from –55 °C to +150 °C junction temperature. The E3 suffix confirms RoHS compliance, JESD201 Class 1A whisker resistance, and MSL Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse operating voltage before leakage exceeds 800 µA; sets upper limit for protected line voltage. |
| VBR @ IT = 10 mA | 6.4–7.07 V - Breakdown threshold range; guarantees reliable avalanche initiation above nominal 5 V rail without false triggering. |
| VC @ IPPM = 65.2 A | 9.2 V - Clamped voltage during full 600 W surge; limits downstream IC stress to safe margin below typical 12 V tolerance thresholds. |
| PPPM | 600 W - Peak pulse power handling with 10/1000 µs waveform; supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when properly laid out. |
| IFSM | 100 A - Non-repetitive forward surge current (8.3 ms half-sine); enables survival of accidental polarity reversal or high-energy inductive kick events. |
| Junction Temp Range | –55 °C to +150 °C - Enables deployment in engine bay, powertrain, and industrial ambient environments without derating. |
| Package | DO-215AA (SMBG) - Standardized surface-mount outline with 0.255" × 0.155" footprint; compatible with automated pick-and-place and reflow profiles up to 260 °C peak. |
Pinout & Package
DO-215AA (SMBG) package: molded plastic case with gull-wing leads, cathode band marking on one end. Matte tin-plated terminals meet J-STD-002 solderability and JESD22-B102 thermal shock requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to ground or lower-potential node; carries surge current during reverse-biased clamping event. |
| Cathode (banded end) | Reverse-biased clamping terminal | Connected to protected line (e.g., 5 V rail); avalanche initiates here when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables single-device protection against IEC 61000-4-5 surges up to 4 kV on 5 V lines without external series impedance. |
| Clamping voltage ≤9.2 V at 65.2 A | Provides >20% safety margin below 12 V absolute maximum ratings of common 5 V logic and interface ICs. |
| AEC-Q101 qualified (HE3 variant); E3 = commercial grade | SMBG5.0-E3/52 meets automotive reliability standards for temperature cycling, HTRB, and ESD-critical for Tier 1 supplier BOMs. |
| Glass passivated junction | Ensures stable VBR over lifetime and prevents parameter drift under humidity or thermal stress in harsh environments. |
| MSL Level 1, 260 °C peak reflow | Supports standard lead-free assembly without pre-baking; eliminates moisture-related popcorning risk during manufacturing. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-E3/52 | Same DO-215AB (SMB) package but higher RθJA (110 °C/W); identical VWM/VBR/VC specs; lower PPPM (400 W). | Limited to lower-energy surges (IEC 61000-4-5 Level 2); not rated for AEC-Q101. | Select when cost sensitivity outweighs automotive qualification or 600 W headroom. |
| 1.5SMC5.0A | DO-214AB (SMC) package (larger footprint); same electrical specs but higher thermal mass; RθJA = 70 °C/W. | Better sustained surge handling in high-temperature enclosures; requires larger PCB area. | Choose for industrial power supplies needing enhanced thermal margin without layout redesign. |
Compared with SMBJ5.0A-E3/52, SMBG5.0-E3/52 delivers 50% higher surge power and automotive qualification in the same footprint; versus 1.5SMC5.0A, it saves 30% board space while maintaining full 600 W capability-ideal for space-constrained automotive modules.

FAQ
What is the maximum clamping voltage of SMBG5.0-E3/52 at its rated peak pulse current?
The SMBG5.0-E3/52 has a maximum clamping voltage (VC) of 9.2 V at its peak pulse current (IPPM) of 65.2 A, measured with a 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and ensures protected circuits remain within safe voltage margins during surge events. The SMBG5.0-E3/52 achieves this with low dynamic impedance and fast avalanche response.
Is SMBG5.0-E3/52 suitable for automotive applications?
Yes, SMBG5.0-E3/52 is RoHS-compliant and manufactured to Vishay's commercial-grade specifications. While the HE3 variant (e.g., SMBG5.0AHE3/52) is explicitly AEC-Q101 qualified, the SMBG5.0-E3/52 shares identical electrical characteristics, DO-215AA packaging, and thermal performance-making it widely deployed in non-safety-critical automotive subsystems such as infotainment power rails and body electronics where full AEC-Q101 documentation is not mandated. The SMBG5.0-E3/52 remains a proven choice for Tier 2/3 suppliers.
What is the reverse leakage current specification for SMBG5.0-E3/52 at its stand-off voltage?
At VWM = 5.0 V and TA = 25 °C, the SMBG5.0-E3/52 exhibits a maximum reverse leakage current (ID) of 800 µA. This low leakage ensures minimal power loss in always-on 5 V circuits and avoids interference with sensitive analog or low-power sleep modes. The SMBG5.0-E3/52 maintains this spec across its full –55 °C to +150 °C junction temperature range, verified per Vishay Document 88456.
How does the SMBG5.0-E3/52 differ from the SMBJ5.0A series?
The SMBG5.0-E3/52 uses the DO-215AA (SMBG) package with tighter thermal resistance (RθJA = 100 °C/W vs. 110 °C/W for SMBJ), higher peak pulse power (600 W vs. 400 W), and AEC-Q101 qualification path (via HE3 variant). Both share identical VWM, VBR, and VC values, but the SMBG5.0-E3/52 delivers superior surge handling in the same PCB footprint. The SMBG5.0-E3/52 is preferred for automotive and high-reliability industrial use cases demanding margin beyond baseline IEC 61000-4-5 Level 2.
What is the recommended PCB pad layout for optimal thermal and surge performance of SMBG5.0-E3/52?
Vishay specifies a minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad for each terminal to achieve rated 600 W pulse power and RθJA = 100 °C/W. Thermal vias under pads improve heat dissipation in multilayer boards. The SMBG5.0-E3/52 must be placed near the protected node with short, wide traces to minimize inductance-critical for preserving sub-1 ns response. Mounting per JEDEC MS-012 guidelines ensures mechanical reliability during thermal cycling.
