Product details
Overview
SMBG5.0A-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMBG (DO-215AA) package, rated for 5.0 V stand-off voltage, 6.4–7.07 V breakdown at 10 mA, 600 W peak pulse power (10/1000 μs), and clamping to 9.2 V at 65.2 A surge current-designed for primary-level overvoltage protection of 5 V logic rails, USB interfaces, and automotive sensor signal lines.
For engineers reviewing the SMBG5.0A-E3/52 datasheet, SMBG5.0A-E3/52 pinout, SMBG5.0A-E3/52 application, or SMBG5.0A-E3/52 equivalent, key selection criteria include verified unidirectional polarity, AEC-Q101 qualification, 800 μA max reverse leakage at 5.0 V, 100 A IFSM surge rating, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, responding within <1 ps to transients exceeding its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5% typical), low incremental surge resistance, and repeatable clamping performance under repetitive 0.01% duty-cycle surges.
The SMBG5.0A-E3/52 is optimized for low-capacitance transient suppression (typ. 600 pF at 0 V, per family data), supports bidirectional variants via CA suffix (e.g., SMBG5.0CA), and meets UL 497B recognition (QVGQ2) and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 5.0 V - Maximum continuous reverse operating voltage before clamping initiates |
| Breakdown Voltage (VBR) | 6.4–7.07 V at 10 mA - Confirmed threshold where device transitions from high-impedance to low-impedance clamping state |
| Clamping Voltage (VC) | 9.2 V at 65.2 A - Peak voltage seen by protected circuit during 600 W transient event |
| Peak Pulse Power (PPPM) | 600 W (10/1000 μs) - Sustained energy absorption capability without failure under standardized surge waveform |
| Reverse Leakage (ID) | 800 μA max at 5.0 V - Minimal parasitic loading on 5 V supply or signal line during normal operation |
| Surge Current (IPPM) | 65.2 A - Peak current handled during clamping; derived directly from VC and PPPM relationship |
| Junction Temp Range | −55 °C to +150 °C - Enables use in under-hood automotive and industrial environments |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-E3/52 | Same SMB package but lower 400 W PPPM rating; 10.3 V clamping at 38.9 A | Limited to lower-energy transients (e.g., IEC 61000-4-2 only, not 61000-4-5) | Select when cost sensitivity outweighs need for full 600 W surge margin |
| SMAJ5.0A-E3/52 | SMA package (smaller footprint); 400 W PPPM; 10.3 V clamping at 38.9 A; higher thermal resistance (RθJA = 140 °C/W) | Not suitable for sustained surge duty or high-temperature enclosures (>85 °C) | Choose only for space-constrained consumer PCBs where automotive qualification is unnecessary |

FAQ
What is the maximum clamping voltage of SMBG5.0A-E3/52 under surge conditions?
The SMBG5.0A-E3/52 has a maximum clamping voltage (VC) of 9.2 V at 65.2 A peak pulse current, measured using the standardized 10/1000 μs waveform. This value ensures protected circuits remain below critical voltage thresholds during worst-case transients, and it is guaranteed across the full operating temperature range (−55 °C to +150 °C) per Vishay Document 88456.
Is SMBG5.0A-E3/52 qualified for automotive applications?
Yes, SMBG5.0A-E3/52 is AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 09-Jan-2024 (Document Number: 88456). This qualification covers stress tests including HTGB, H3TRB, and temperature cycling, validating its suitability for under-hood and cabin-mounted automotive electronics such as engine control units and ADAS sensor modules.
Does SMBG5.0A-E3/52 have bidirectional capability?
No, SMBG5.0A-E3/52 is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., SMBG5.0CA) and lack polarity marking. The electrical characteristics for SMBG5.0A-E3/52 apply only in reverse-biased mode; forward conduction follows standard diode behavior with VF ≈ 3.5 V at 50 A.
What is the recommended PCB pad layout for SMBG5.0A-E3/52?
Vishay specifies mounting SMBG5.0A-E3/52 on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power dissipation. Smaller pads reduce thermal mass and cause premature failure under repeated surges. The pad layout must maintain minimum solder mask clearance and follow DO-215AA mechanical outline dimensions to ensure coplanarity and reflow yield.
How does SMBG5.0A-E3/52 compare to SMAJ5.0A-E3/52 in terms of surge handling?
SMBG5.0A-E3/52 handles 600 W peak pulse power with 9.2 V clamping at 65.2 A, whereas SMAJ5.0A-E3/52 is rated for only 400 W and clamps at 10.3 V under lower 38.9 A surge current. Additionally, SMBG5.0A-E3/52 features lower thermal resistance (RθJL = 20 °C/W vs. ~35 °C/W for SMAJ), enabling superior energy dissipation in thermally constrained layouts.
