Product details
Overview
SMCG100CA-E3/9AT from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for high-energy surge protection with 100 V standoff voltage (VWM), 1500 W peak pulse power (PPPM), and clamping voltage of 162 V at 9.3 A IPPM. It protects signal lines and power rails in automotive sensor interfaces and industrial I/O modules.
For engineers reviewing the SMCG100CA-E3/9AT datasheet, SMCG100CA-E3/9AT pinout, SMCG100CA-E3/9AT application, or SMCG100CA-E3/9AT equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification, 1500 W surge rating, DO-215AB thermal performance (RθJA = 75 °C/W), and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This device operates as a bidirectional avalanche diode, leveraging glass-passivated junction technology to achieve sub-nanosecond response time and low incremental surge resistance. Its breakdown voltage (VBR) ranges from 111 V to 123 V at 1 mA test current, with clamping voltage VC = 162 V measured at IPPM = 9.3 A under 10/1000 µs waveform.
Designed for unclamped inductive switching transients and lightning-induced surges, it maintains stable performance across -55 °C to +150 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Polarity is unmarked for bidirectional operation, and terminals are matte tin-plated for solderability per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 111 V / 123 V at IT = 1 mA - ensures reliable avalanche conduction onset within tight tolerance |
| VC @ IPPM | 162 V at 9.3 A - clamping voltage limits downstream IC stress during 10/1000 µs surge events |
| PPPM | 1500 W - peak transient energy absorption capability under standardized surge waveform |
| ID @ VWM | 1.0 µA - ultra-low leakage preserves signal integrity in high-impedance sensor circuits |
| TJ max | +150 °C - enables use in under-hood automotive environments and thermally constrained enclosures |
| RθJA | 75 °C/W - thermal resistance defines required PCB copper area (8.0 mm × 8.0 mm per terminal) for safe 6.5 W dissipation |
Pinout & Package
Package: SMCG (DO-215AB) - surface-mount, low-profile gull-wing leaded package with matte tin-plated terminals; meets UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (bidirectional) | Acts as cathode during positive half-cycle; no marking distinguishes polarity in CA variants |
| Cathode | Transient current exit (bidirectional) | Acts as anode during negative half-cycle; symmetric conduction eliminates orientation dependency |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan |
| Glass passivated junction | Enables stable VBR tolerance and long-term parameter stability under thermal and humidity stress |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns response), critical for protecting 3.3 V/5 V logic |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow without preconditioning or baking, reducing manufacturing complexity |
| 1500 W 10/1000 µs rating | Provides robust protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 4 surges |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100CA | Lower PPPM (400 W), SMA (DO-214AC) package, RθJA = 110 °C/W | Suitable for lower-energy surges; requires larger PCB copper for thermal management | Select when cost sensitivity outweighs surge margin and board space allows larger pad layout |
| SMCJ100CA | Higher PPPM (1500 W), same DO-215AB package, but higher VBR (111–123 V vs. 111–123 V identical), same clamping | Functionally identical clamping performance; differs only in JEDEC prefix and internal lot traceability | Acceptable drop-in alternative where Vishay SMCJ-series sourcing is preferred for supply chain diversification |
Compared with SMAJ100CA, SMCG100CA-E3/9AT delivers 275 % higher surge power handling in the same footprint; versus SMCJ100CA, it shares identical electrical specs but carries distinct AEC-Q101 qualification evidence and E3 suffix RoHS compliance documentation.

FAQ
What is the clamping voltage of SMCG100CA-E3/9AT under a 10/1000 µs surge?
The SMCG100CA-E3/9AT clamps to 162 V when subjected to its rated peak pulse current of 9.3 A under the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and verified on the minimum recommended 8.0 mm × 8.0 mm copper pad layout specified in the datasheet.
Is SMCG100CA-E3/9AT suitable for automotive applications?
Yes, SMCG100CA-E3/9AT is AEC-Q101 qualified and explicitly rated for automotive use. Its construction-including glass-passivated junction, MSL Level 1 rating, and operation from -55 °C to +150 °C-supports deployment in engine control units, body electronics, and ADAS sensor interfaces per ISO 16750 and ISO 7637-2 requirements.
Does SMCG100CA-E3/9AT have polarity markings on the package?
No, SMCG100CA-E3/9AT is a bidirectional TVS diode and carries no polarity marking on the SMCG (DO-215AB) package. The device functions identically regardless of orientation, with symmetrical breakdown and clamping characteristics in both directions, eliminating placement errors during automated assembly.
What is the maximum steady-state power dissipation for SMCG100CA-E3/9AT?
The SMCG100CA-E3/9AT has a maximum steady-state power dissipation (PD) of 6.5 W when mounted on infinite heatsink at TA = 50 °C. In practical PCB layouts, derating applies per Figure 2 in the datasheet, and thermal design must account for RθJA = 75 °C/W using the recommended 8.0 mm × 8.0 mm copper pads per terminal.
How does the E3/9AT suffix affect the specifications of SMCG100CA-E3/9AT?
The E3 suffix denotes RoHS-compliant, industrial-grade construction with matte tin-plated leads; the 9AT indicates packaging in 13-inch diameter tape-and-reel format with 3500 units per reel. Neither suffix alters electrical or thermal specifications-these are purely material compliance and logistics identifiers per Vishay's ordering nomenclature.
