Product details
Overview
SMCG10-E3/9AT from Vishay General Semiconductor is a bi-directional surface-mount Transient Voltage Suppressor (TVS) in the DO-215AB (SMCG) package, designed for clamping voltage transients on signal or power lines. It features a 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage (VC) at 88.2 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with a 10/1000 µs waveform.
For engineers reviewing the SMCG10-E3/9AT datasheet, SMCG10-E3/9AT pinout, SMCG10-E3/9AT application, or SMCG10-E3/9AT equivalent, key selection criteria include clamping performance under 10/1000 µs surge, bi-directional symmetry for AC-coupled lines, AEC-Q101 qualification for automotive use, and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with breakdown voltage (VBR) specified as 11.1–12.3 V at 1.0 mA test current and reverse leakage (ID) ≤5.0 µA at 10 V VWM. Its low incremental surge resistance enables stable clamping during fast transients, while the glass-passivated junction ensures robust reliability under repetitive surge stress.
The device is rated for TJ = –55 °C to +150 °C operation, features a thermal resistance of 75 °C/W (junction-to-ambient, on 8.0 mm × 8.0 mm copper pads), and meets MSL Level 1 per J-STD-020 with 260 °C peak reflow tolerance - confirming suitability for high-volume, lead-free SMT assembly without moisture sensitivity concerns.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A-E3/57T | Uni-directional; 10 V VWM, 17.0 V VC, same PPPM/PPM but lacks bi-directional symmetry | Requires external polarity management; unsuitable for AC-coupled or differential lines without series blocking diodes | Select only when protecting DC-biased single-ended signals where polarity is fixed and cost is prioritized over layout simplicity |
| SMCJ10CA-E3/9AT | Same bi-directional function, DO-214AB (SMC) package; 10 V VWM, 17.0 V VC, 1500 W PPPM, but larger footprint (7.11 mm × 6.22 mm vs. 7.87 mm × 3.17 mm) | Higher thermal mass improves surge repetition rate but consumes ~2.5× board area; incompatible with tight-pitch automotive connectors | Prefer when higher surge repetition tolerance is needed and board space permits; avoid in space-constrained ADAS camera modules |
Compared with SMAJ10A-E3/57T and SMCJ10CA-E3/9AT, SMCG10-E3/9AT delivers identical clamping performance in a smaller, bi-directional package optimized for automated placement - making it the preferred choice for compact, differential, or AC-coupled protection where board area and polarity flexibility are critical.

FAQ
What is the clamping voltage of SMCG10-E3/9AT at its rated peak pulse current?
The SMCG10-E3/9AT has a maximum clamping voltage (VC) of 17.0 V when subjected to its rated peak pulse current (IPPM) of 88.2 A using the standard 10/1000 µs waveform. This value is measured across the device terminals under defined test conditions per JEDEC standards and represents the upper voltage limit imposed on the protected circuit during surge events - a critical parameter for ensuring downstream ICs remain within absolute maximum ratings.
Is SMCG10-E3/9AT suitable for automotive applications?
Yes, SMCG10-E3/9AT is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes a glass-passivated junction, MSL Level 1 reflow compatibility, and guaranteed operation from –55 °C to +150 °C. These attributes validate its deployment in engine control units, body control modules, and ADAS sensor interfaces where reliability under thermal cycling, vibration, and repeated surge stress is mandatory - confirmed by Vishay's official qualification report referenced in document 88457.
Does SMCG10-E3/9AT have polarity markings?
No, SMCG10-E3/9AT does not have polarity markings because it is a bi-directional TVS diode. The device functions identically regardless of orientation on the PCB - both terminals are electrically symmetrical. This eliminates orientation errors during automated placement and simplifies layout for differential or AC-coupled signal lines, unlike uni-directional variants (e.g., SMCG10A) which feature a cathode band.
What is the recommended PCB pad layout for SMCG10-E3/9AT?
Vishay specifies a minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pad area for each terminal of SMCG10-E3/9AT to achieve rated thermal dissipation and surge current handling. This layout ensures the device meets its 1500 W PPPM and 75 °C/W RθJA specifications. Deviating from this pad size - especially reducing copper area - degrades clamping consistency and may cause premature failure during repetitive surges, as confirmed in Figure 2 of datasheet 88457.
How does SMCG10-E3/9AT differ from SMCG10A?
SMCG10-E3/9AT is the bi-directional version (suffix "CA" implied by "E3/9AT" ordering code context and family documentation), whereas SMCG10A is uni-directional. The key difference is symmetry: SMCG10-E3/9AT clamps equally in both polarities with no cathode marking, enabling protection of AC signals or differential buses like CAN without polarity constraints; SMCG10A requires correct orientation and only clamps in reverse bias, making it unsuitable for bidirectional line protection without additional circuitry.
