Product details
Overview
SMCG130CAHE3/9AT 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 1500 W peak pulse power (10/1000 µs), 130 V standoff voltage (VWM), and clamping voltage of 209 V at rated surge current. It is AEC-Q101 qualified and used to protect automotive sensor signal lines, power rails, and I/O interfaces against ESD and load dump transients.
For engineers reviewing the SMCG130CAHE3/9AT datasheet, SMCG130CAHE3/9AT pinout, SMCG130CAHE3/9AT application, or SMCG130CAHE3/9AT equivalent, key selection criteria include bidirectional clamping behavior, 130 V VWM rating, 209 V VC at IPPM, AEC-Q101 qualification, and DO-215AB surface-mount compatibility with automated assembly.
Technical Context
This device operates as a voltage-clamped crowbar during transient events, leveraging an avalanche breakdown mechanism to shunt surge current away from downstream circuitry. Its bidirectional symmetry ensures identical clamping performance in both polarities, with no polarity marking required on the package.
Designed for automotive-grade reliability, SMCG130CAHE3/9AT features glass-passivated junctions, meets MSL Level 1 per J-STD-020, withstands 260 °C lead-free reflow, and delivers stable clamping up to 150 °C junction temperature - validated under AEC-Q101 stress testing including HTGB, HTRB, and TCT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 144 V / 159 V at 1 mA - guaranteed breakdown threshold range for reliable turn-on |
| VC @ IPPM | 209 V at 7.2 A (10/1000 µs) - clamping voltage limiting downstream voltage stress |
| PPPM | 1500 W - peak surge energy handling capacity under standardized waveform |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| Package | SMCG (DO-215AB) - low-profile SMD outline with 0.220–0.245" body length and matte tin leads |
| AEC-Q101 | Qualified - certified for automotive electronics per stress test requirements including temperature cycling and humidity bias |
Pinout & Package
SMCG130CAHE3/9AT uses a 2-terminal bidirectional configuration in the SMCG (DO-215AB) package. No polarity marking is present; both terminals are functionally symmetric. The package features gull-wing leads compatible with standard SMT reflow profiles and meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Either terminal serves as anode or cathode depending on transient polarity; no fixed polarity |
| Terminal 2 | Anode/Cathode (bidirectional) | Electrically identical to Terminal 1; symmetrical conduction path enables dual-direction protection |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC performance in both directions eliminates need for polarity-aware layout |
| AEC-Q101 qualification | Validated for automotive applications including engine control units and ADAS sensor interfaces |
| Glass-passivated junction | Enhances long-term reliability and stability of breakdown characteristics over temperature and life |
| MSL Level 1 rating | Enables use without dry-packaging or baking prior to assembly in high-volume manufacturing |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a/5a) |
Applications
| Automotive Sensor Protection | Industrial CAN Bus Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130CA | Same VWM (130 V) and PPPM (1500 W), but SMA (DO-214AC) package - larger footprint and higher RθJA (90 °C/W vs. 75 °C/W) | Limited to non-automotive industrial use due to lack of AEC-Q101 qualification | Select when board space allows larger package and automotive qualification is not required |
| 1.5KE130CA | Higher power (1500 W), same VWM, but axial-leaded DO-15 package - unsuitable for automated SMT assembly | Restricted to prototyping or through-hole legacy designs; incompatible with reflow soldering | Choose only for manual assembly or repair scenarios where SMT is unavailable |
Compared with SMAJ130CA and 1.5KE130CA, SMCG130CAHE3/9AT offers superior thermal performance (RθJA = 75 °C/W), AEC-Q101 qualification for automotive deployment, and DO-215AB packaging optimized for high-density SMT layouts - making it the preferred choice for production automotive and industrial modules requiring reliability and manufacturability.

FAQ
What is the clamping voltage of SMCG130CAHE3/9AT at its rated peak pulse current?
The clamping voltage (VC) of SMCG130CAHE3/9AT is 209 V when subjected to its rated peak pulse current (IPPM) of 7.2 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable voltage limiting during surge events, protecting downstream components such as microcontrollers and transceivers from overvoltage damage. The specification is guaranteed across the full operating temperature range.
Is SMCG130CAHE3/9AT suitable for automotive applications?
Yes, SMCG130CAHE3/9AT is AEC-Q101 qualified and explicitly designed for automotive use. It passes all required stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT). Its 130 V VWM and 209 V clamping voltage align with ISO 7637-2 Pulse 5a load dump requirements for 24 V systems, and its DO-215AB package supports automated SMT assembly in automotive ECUs and ADAS modules.
Does SMCG130CAHE3/9AT have polarity markings on the package?
No, SMCG130CAHE3/9AT does not have polarity markings because it is a bidirectional TVS diode. Both terminals are functionally identical, and the device provides symmetrical clamping in either direction. This eliminates orientation concerns during placement and simplifies PCB layout - unlike unidirectional variants (e.g., SMCG130A), which feature a cathode band marking.
What is the thermal resistance of SMCG130CAHE3/9AT, and how does it affect power dissipation?
SMCG130CAHE3/9AT 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 lower RθJA compared to SMA packages enables higher sustained power handling in compact layouts. At TA = 50 °C, its rated power dissipation is 6.5 W - critical for thermal design in enclosed automotive enclosures where ambient temperatures exceed 85 °C.
How does the SMCG (DO-215AB) package of SMCG130CAHE3/9AT compare to SMA (DO-214AC) in terms of board space and thermal performance?
The SMCG (DO-215AB) package of SMCG130CAHE3/9AT occupies ~30% less board area than SMA (DO-214AC) and achieves a lower RθJA of 75 °C/W versus ~90 °C/W for SMAJ equivalents. Its gull-wing lead geometry improves solder joint reliability and process yield in high-speed pick-and-place assembly. These advantages make SMCG130CAHE3/9AT preferable for space-constrained automotive modules where thermal density and manufacturing efficiency are critical.
