Product details
Overview
SMCG8.0CA-M3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, with 8.0 V stand-off voltage (VWM), 13.6 V maximum clamping voltage (VC) at 110.3 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM). It is AEC-Q101 qualified and designed for automotive-level surge protection on signal lines and power rails.
For engineers reviewing the SMCG8.0CA-M3/57T datasheet, SMCG8.0CA-M3/57T pinout, SMCG8.0CA-M3/57T application, or SMCG8.0CA-M3/57T equivalent, key selection criteria include bidirectional clamping behavior, 1500 W surge rating, DO-215AB thermal performance (RθJA = 75 °C/W), AEC-Q101 qualification, and halogen-free RoHS compliance per M3 suffix.
Technical Context
This device operates as a bidirectional voltage-clamping protector, leveraging an avalanche breakdown mechanism to limit transient overvoltages across both polarities. Its breakdown voltage (VBR) ranges from 8.89 V to 9.83 V at 1 mA test current, with symmetrical response in forward and reverse directions due to its center-tapped, non-polarized construction.
The SMCG8.0CA-M3/57T delivers fast response time (<1 ns), low incremental surge resistance, and stable clamping under 10/1000 μs waveform stress. It is rated for TJ = –55 °C to +150 °C operation and meets J-STD-020 MSL Level 1 reflow compatibility with 260 °C peak temperature.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0CA | Same VWM (8.0 V) and VC (13.6 V), but lower PPPM (400 W); SMA (DO-214AC) package with higher RθJA (105 °C/W). | Not suitable for automotive load-dump or high-repetition surges; limited to consumer-grade ESD-only protection. | Select SMAJ8.0CA only when board space allows larger SMA footprint and surge energy is ≤400 W. |
| SMCJ8.0CA | Same VWM (8.0 V) and higher PPPM (1500 W), but larger SMC (DO-214AB) package; RθJA = 40 °C/W on same pad layout. | Better thermal performance but requires 30% more PCB area; not AEC-Q101 qualified in standard M3 variant. | Choose SMCJ8.0CA when thermal headroom is critical and AEC-Q101 is not mandated; verify qualification status per batch. |
Compared with SMAJ8.0CA and SMCJ8.0CA, the SMCG8.0CA-M3/57T uniquely combines AEC-Q101 qualification, DO-215AB compactness, and full 1500 W surge capability-making it optimal for space-constrained automotive and industrial modules requiring certified reliability.

FAQ
What is the clamping voltage of SMCG8.0CA-M3/57T under maximum surge conditions?
The SMCG8.0CA-M3/57T has a maximum clamping voltage (VC) of 13.6 V at 110.3 A peak pulse current (IPPM), measured using the standard 10/1000 μs waveform. This value ensures downstream circuitry remains protected below critical voltage thresholds during high-energy transients such as ISO 7637-2 pulses or ESD events. The SMCG8.0CA-M3/57T maintains this clamping performance across its full operating temperature range.
Is SMCG8.0CA-M3/57T suitable for automotive applications?
Yes, the SMCG8.0CA-M3/57T is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its halogen-free M3 suffix, MSL Level 1 reflow rating, and guaranteed operation from –55 °C to +150 °C meet OEM requirements. The SMCG8.0CA-M3/57T is referenced in Vishay's automotive-grade transient suppressor portfolio for load-dump and ESD protection.
How does the SMCG8.0CA-M3/57T differ from unidirectional variants like SMCG8.0A-M3/57T?
The SMCG8.0CA-M3/57T is bidirectional, meaning it clamps transients of either polarity symmetrically, with identical VBR and VC characteristics in both directions. In contrast, SMCG8.0A-M3/57T is unidirectional and features a cathode band marking; it conducts only in reverse bias and cannot protect AC or floating nodes. The SMCG8.0CA-M3/57T is used where polarity is undefined or alternating, such as data lines or transformer-coupled circuits.
What is the thermal resistance of SMCG8.0CA-M3/57T, and how does it affect layout?
The SMCG8.0CA-M3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes minimum recommended pad layout per Vishay's datasheet. To maintain reliability under repeated surges, designers must allocate adequate copper area and avoid thermal bottlenecks-undersized pads will raise junction temperature and reduce surge endurance. The SMCG8.0CA-M3/57T's RθJL of 15 °C/W further emphasizes the importance of solid lead-to-plane connections.
Does SMCG8.0CA-M3/57T require orientation during PCB placement?
No, the SMCG8.0CA-M3/57T does not require specific orientation because it is a bidirectional device with no polarity marking on the package. Unlike unidirectional variants (e.g., SMCG8.0A-M3/57T), which feature a cathode band, the SMCG8.0CA-M3/57T functions identically regardless of PCB placement direction. This simplifies automated assembly and eliminates orientation-related assembly errors in high-volume production of the SMCG8.0CA-M3/57T.
