Product details
Overview
SMBG10-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for clamping inductive switching transients and ESD events on power and signal lines. It features 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V maximum clamping voltage (VC) at 35.3 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 µs waveform - used in automotive sensor protection and industrial I/O interface circuits.
For engineers reviewing the SMBG10-E3/52 datasheet, SMBG10-E3/52 pinout, SMBG10-E3/52 application, or SMBG10-E3/52 equivalent, key selection criteria include unidirectional polarity, 10 V reverse stand-off capability, 17.0 V clamping performance under 35.3 A surge, RoHS-compliant commercial-grade construction (E3 suffix), and AEC-Q101 qualification readiness via HE3 variant.
Technical Context
This TVS diode operates as a voltage-clamping protection device placed in parallel with sensitive circuit nodes. Its glass-passivated junction enables fast response (<1 ns), low incremental surge resistance, and stable clamping across temperature (–55 °C to +150 °C junction range).
The SMBG10-E3/52 is rated for 600 W peak pulse power (10/1000 µs), supports 100 A non-repetitive forward surge current (8.3 ms half-sine), and exhibits 800 µA max reverse leakage at VWM - optimized for automated SMT placement on 5.0 mm × 5.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 11.1 V / 12.3 V at 1 mA - ensures reliable breakdown onset within tight tolerance band |

| PPPM | 600 W (10/1000 µs) - peak surge energy handling capacity for inductive load switching |
| IFSM | 100 A (8.3 ms half-sine) - withstands single high-current surge without failure |
| TJ max | +150 °C - enables operation in under-hood automotive and industrial ambient environments |

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from ISO 7637-2 pulse 1/2a/5a transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and ground to clamp negative-going transients and limit positive excursions to ≤17.0 V. Use Value: Prevents latch-up or damage to 3.3 V/5 V microcontrollers and signal conditioners during vehicle battery disconnection or alternator load dump. | Use Scenario: Safeguarding digital input modules in programmable logic controllers exposed to inductive kickback from solenoids and contactors. IC Role / Device Role / Timing Role: Parallel-connected transient suppressor on 24 V DC input lines, activated within <1 ns to hold voltage below 17.0 V during 100 A surge events. Use Value: Eliminates need for external series impedance or RC snubbers while maintaining immunity to IEC 61000-4-4 level 4 (4 kV) fast transients. |
| Consumer Power Adapter Input | Telecom Line Interface Protection |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters subjected to lightning-induced surges on DC output rails. IC Role / Device Role / Timing Role: Standoff-rated TVS (10 V) placed across regulated 12 V output to absorb repetitive 600 W pulses without thermal runaway.

Use Value: Limits clamping overshoot to 17.0 V while adding negligible signal distortion due to absence of parasitic capacitance impact on 100 MHz+ data paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A-E3/52 | Same DO-214AA (SMB) package but 10% higher VC (18.0 V vs. 17.0 V); identical VWM/VBR/PPPM ratings | Slightly higher clamping increases risk of overvoltage stress on 12 V tolerant ICs; preferred where margin allows | Select SMBJ10A-E3/52 only if PCB pad layout accommodates larger SMB footprint and system tolerates 1.0 V higher clamping |
| SMBG10HE3/52 | Identical electrical specs and DO-215AA package; differs only in AEC-Q101 qualification and JESD201 Class 2 whisker testing | Required for automotive production; not necessary for commercial/industrial designs without qualification mandates | Choose SMBG10HE3/52 when automotive OEM compliance is mandatory; otherwise SMBG10-E3/52 suffices for cost-sensitive applications |
Compared with SMBJ10A-E3/52 and SMBG10HE3/52, the SMBG10-E3/52 offers optimal balance of compact DO-215AA footprint, lowest clamping voltage (17.0 V), and commercial-grade cost structure - making it ideal for space-constrained industrial and consumer designs where AEC-Q101 is not required.

FAQ
What is the clamping voltage of SMBG10-E3/52 under maximum rated surge current?
The SMBG10-E3/52 has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPPM) of 35.3 A, measured using the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during a 600 W transient event and is guaranteed across the full operating temperature range of –55 °C to +150 °C. The SMBG10-E3/52 achieves this performance through a tightly controlled glass-passivated junction and low dynamic impedance design.
Is SMBG10-E3/52 suitable for automotive applications?
The SMBG10-E3/52 itself is RoHS-compliant and built to commercial-grade specifications (E3 suffix), but it is not AEC-Q101 qualified. However, its direct variant SMBG10HE3/52 carries full AEC-Q101 qualification and shares identical electrical characteristics and DO-215AA packaging. For production automotive use, SMBG10HE3/52 is required; SMBG10-E3/52 may be used in automotive prototyping or non-safety-critical subsystems where qualification is not mandated. The SMBG10-E3/52 remains fully compatible in layout and function with its qualified counterpart.
What is the meaning of the "-E3/52" suffix in SMBG10-E3/52?
The "-E3" suffix indicates RoHS-compliant construction with matte tin-plated leads meeting J-STD-002 solderability and JESD201 Class 1A whisker resistance requirements. The "/52" denotes packaging in 7-inch plastic tape-and-reel format with a base quantity of 750 units per reel. This ordering code ensures consistent assembly-line compatibility for automated pick-and-place equipment and aligns with IPC-7351B land pattern recommendations for DO-215AA (SMBG) devices. The SMBG10-E3/52 is supplied with full traceability documentation per lot.
How does SMBG10-E3/52 compare to SMAJ10A in terms of package and performance?
The SMBG10-E3/52 uses the smaller DO-215AA (SMBG) package (body size 3.94 mm × 2.10 mm), whereas SMAJ10A uses the larger DO-214AC (SMA) package (4.57 mm × 2.92 mm). Electrically, SMBG10-E3/52 offers lower clamping voltage (17.0 V vs. 18.2 V) and higher peak pulse current (35.3 A vs. 32.9 A) at the same 600 W rating. Its thermal resistance (RθJA = 100 °C/W) is also superior to SMAJ10A's 125 °C/W, enabling better power dissipation in dense layouts. The SMBG10-E3/52 thus delivers enhanced protection density and thermal performance in the same functional role.
Does SMBG10-E3/52 require a heatsink for standard operation?
No, the SMBG10-E3/52 does not require an external heatsink under normal transient suppression duty cycles. Its thermal design relies on PCB copper pad conduction: mounting on minimum 5.0 mm × 5.0 mm copper pads per terminal achieves the specified RθJA of 100 °C/W, allowing full 600 W pulse handling without exceeding the +150 °C maximum junction temperature. Heatsinking is unnecessary unless operating under continuous high-frequency surge repetition (>0.01% duty cycle) or in extreme ambient conditions (>105 °C), where thermal simulation of the actual layout is recommended. The SMBG10-E3/52 is optimized for self-contained PCB-level thermal management.
