Product details
Overview
SMCG100A-E3/9AT from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMCG (DO-215AB) package, with a 100 V stand-off voltage (VWM), 111–123 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and 9.3 A maximum clamping current (IPPM) at 162 V clamping voltage (VC). It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in automotive and industrial power electronics.
For engineers reviewing the SMCG100A-E3/9AT datasheet, SMCG100A-E3/9AT pinout, SMCG100A-E3/9AT application, or SMCG100A-E3/9AT equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), polarity marking (cathode band), and reel packaging details (13" tape, 3500 pcs/reel) critical for ESD/surge protection design-in and BOM validation.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, triggering when reverse voltage exceeds its breakdown threshold (VBR = 111–123 V at IT = 1 mA) to divert surge current away from sensitive components. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time under 10/1000 μs transients.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it delivers 1500 W peak pulse power handling with low incremental surge resistance and meets MSL Level 1 (260 °C reflow peak), supporting automated placement in high-reliability automotive modules and industrial controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working range for DC-biased signal/power lines. |
| VBR (min/max) | 111 V / 123 V at 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on during overvoltage events without premature conduction. |
| VC @ IPPM | 162 V at 9.3 A - Clamping voltage under full 10/1000 μs surge; limits stress on downstream ICs to ≤162 V during 1500 W transient dissipation. |
| PPPM | 1500 W - Peak pulse power rating; enables robust protection against IEC 61000-4-5 Level 4 (4 kV) surges when properly mounted. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance; requires ≥8 mm × 8 mm copper pad per lead to sustain 6.5 W steady-state power at TA = 50 °C. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing; suitable for engine control, ADAS, and body electronics. |
Pinout & Package
Package: SMCG (DO-215AB) - Low-profile, gull-wing surface-mount case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; polarity marked by cathode band on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to ground or low-side reference in unidirectional configuration. | Provides return path for surge current during clamping; must be routed with low-inductance trace to minimize VC overshoot. |
| Cathode | Current exit point in forward bias; marked with band; connected to protected line (e.g., 12 V rail or CAN signal). | Defines polarity-sensitive connection-reversal disables clamping function and risks catastrophic failure under reverse surge. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance and <1.0 μA ID at VWM across -55 °C to +150 °C operating range, critical for long-term field reliability. |
| Low incremental surge resistance | Minimizes VC rise during fast transients, enabling effective clamping of sub-microsecond ESD events without excessive voltage overshoot. |
| AEC-Q101 qualification | Validates suitability for automotive applications requiring extended temperature operation, humidity resistance, and mechanical shock endurance. |
| MSL Level 1 rating | Supports standard SMT reflow profiles up to 260 °C peak without moisture-induced delamination or popcorn failure. |
Applications
| Automotive Power Distribution | Industrial Sensor Interface Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100A-E3/57T | Same VWM (100 V), lower PPPM (400 W), SMA (DO-214AC) package with higher RθJA (110 °C/W). | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 without derating. | Select when cost or board space constraints outweigh peak surge requirements. |
| SMCJ100A-E3/9AT | Same VWM (100 V), identical PPPM (1500 W), but larger SMC (DO-214AB) package with higher thermal mass and RθJA = 50 °C/W. | Better thermal performance under sustained surge duty cycles; requires larger PCB footprint. | Choose for high-reliability industrial systems where thermal margin is prioritized over miniaturization. |
Compared with SMAJ100A-E3/57T and SMCJ100A-E3/9AT, the SMCG100A-E3/9AT delivers identical surge capability in a smaller DO-215AB footprint with AEC-Q101 qualification-making it optimal for space-constrained automotive modules needing certified reliability without thermal compromise.

FAQ
What is the clamping voltage of SMCG100A-E3/9AT under a 10/1000 µs surge?
The SMCG100A-E3/9AT has a maximum clamping voltage (VC) of 162 V at 9.3 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per terminal and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The SMCG100A-E3/9AT maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C).
Is SMCG100A-E3/9AT qualified for automotive applications?
Yes, the SMCG100A-E3/9AT is AEC-Q101 qualified, having passed rigorous stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD) per JESD22-A114. This qualification confirms its suitability for use in automotive subsystems such as engine control units, body electronics, and ADAS sensor interfaces where long-term reliability under harsh environmental conditions is mandatory. The SMCG100A-E3/9AT carries the HE3 suffix variant for AEC-Q101 compliance, and the E3/9AT version retains full qualification per Vishay documentation.
What does the "E3/9AT" suffix indicate in SMCG100A-E3/9AT?
The "E3" suffix denotes RoHS-compliant, industrial-grade construction with matte tin-plated leads meeting J-STD-002 and JESD 22-B102 solderability standards. The "9AT" specifies the packaging format: 13-inch diameter plastic tape-and-reel containing 3500 units, optimized for high-volume SMT assembly. This differs from the "57T" option (7-inch reel, 850 units). Both E3 variants meet JESD201 Class 2 whisker resistance requirements, and the SMCG100A-E3/9AT is fully compatible with standard reflow profiles up to 260 °C peak.
How does SMCG100A-E3/9AT compare to bidirectional TVS diodes like SMCG100CA?
The SMCG100A-E3/9AT is unidirectional and features a cathode band for polarity-sensitive installation, whereas SMCG100CA is bidirectional with no polarity marking and symmetric clamping in both directions. Electrical characteristics-including VWM (100 V), VBR (111–123 V), and VC (162 V)-are identical in magnitude but apply across both polarities for the CA variant. The SMCG100A-E3/9AT is selected when protecting DC-biased lines (e.g., 12 V supplies), while SMCG100CA suits AC-coupled or differential signal paths like RS-485 or CAN bus. Both share the same SMCG (DO-215AB) package and AEC-Q101 qualification.
What thermal design guidance applies to SMCG100A-E3/9AT in continuous operation?
For continuous operation, the SMCG100A-E3/9AT has a power dissipation rating (PD) of 6.5 W at TA = 50 °C, with a junction-to-ambient thermal resistance (RθJA) of 75 °C/W. To avoid exceeding the 150 °C maximum junction temperature, PCB layout must use minimum 8.0 mm × 8.0 mm copper pads per terminal as specified in Vishay's mounting guidelines. Derating is required above 50 °C ambient: PD decreases linearly to zero at 150 °C. The SMCG100A-E3/9AT does not require a heatsink for typical transient-only duty cycles, but sustained power dissipation demands careful thermal analysis using the provided RθJA value.
