Overview
SMCG130CA-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 on signal and power lines. It features a 130 V stand-off voltage (VWM), 1500 W peak pulse power (PPPM), clamping voltage of 209 V at 7.2 A IPPM, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMCG130CA-E3/9AT datasheet, SMCG130CA-E3/9AT pinout, SMCG130CA-E3/9AT application, or SMCG130CA-E3/9AT equivalent, this device is selected for robust ESD and lightning surge protection in automotive sensor interfaces, industrial I/O modules, and telecom line cards where bidirectional clamping, low leakage (<1 μA at VWM), and MSL Level 1 reflow compatibility are critical.
Technical Context
The SMCG130CA-E3/9AT implements a glass-passivated silicon avalanche junction optimized for fast response (<1 ns) to transients and low incremental surge resistance. Its bidirectional architecture enables symmetrical clamping in AC-coupled or floating circuits without polarity constraints.
It operates across -55 °C to +150 °C junction temperature, with thermal resistance RθJA = 75 °C/W and RθJL = 15 °C/W, supporting stable performance under repeated surge stress when mounted on 8.0 mm × 8.0 mm copper pads per terminal.
Key Specifications

|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working range for protected circuitry. |
| VBR (min/max) | 144 V / 159 V - Breakdown voltage range at 1 mA test current; ensures predictable turn-on threshold with tight tolerance. |
| VC @ IPPM | 209 V at 7.2 A - Clamping voltage during 10/1000 µs surge; limits downstream voltage stress to safe levels. |
| PPPM | 1500 W - Peak pulse power handling capability; supports high-energy transients like ISO 7637-2 Pulse 5a. |
| ID @ VWM | <1 μA - Reverse leakage at stand-off voltage; minimizes standby power loss and avoids false triggering. |
| TJ max. | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |
| MSL Level | Level 1 (260 °C peak) - Supports standard lead-free reflow without moisture sensitivity concerns. |
Pinout & Package

| Telecom Line Interface | Power Supply Input Stage |
Use Scenario: Protecting Ethernet PHY or RS-485 transceivers connected to outdoor cabling exposed to lightning-induced surges. IC Role / Device Role / Timing Role: First-stage transient suppressor on differential pair, upstream of common-mode chokes and receiver ICs. Use Value: Clamps common-mode surges up to 1500 W without degrading signal integrity due to low junction capacitance (~50 pF typical). |
Use Scenario: Secondary surge suppression on 12–48 V DC input rails of embedded power supplies after primary MOV or GDT stages. IC Role / Device Role / Timing Role: Fast-response clamp limiting residual transients that bypass slower primary protectors. Use Value: Reduces peak voltage seen by downstream DC-DC controllers to <210 V, preventing overvoltage shutdown or FET avalanche failure. |
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 (400 W), but lower power rating and SMA (DO-214AC) package with higher RθJA (110 °C/W). | Limited to lower-energy transients (IEC 61000-4-5 Level 2); unsuitable for automotive load dump or industrial 4 kV testing. | Select SMAJ130CA only for cost-sensitive, non-automotive applications with verified lower surge exposure. |
| SMBJ130CA | Same VWM (130 V), higher PPPM (600 W), SMB (DO-214AA) package, RθJA = 90 °C/W, and AEC-Q101 qualified. | Supports moderate surge levels but lacks the 1500 W headroom and thermal margin of SMCG130CA-E3/9AT for sustained multi-pulse events. | Choose SMBJ130CA where board space is constrained and 600 W protection suffices-e.g., secondary protection in compact consumer power adapters. |
Compared with SMAJ130CA and SMBJ130CA, the SMCG130CA-E3/9AT delivers 2.5× and 2.5× higher peak pulse power respectively, with superior thermal dissipation (RθJA = 75 °C/W) and full AEC-Q101 validation-making it the only option rated for automotive-grade 1500 W surge immunity in DO-215AB form factor.

FAQ
What is the clamping voltage of SMCG130CA-E3/9AT at its rated peak pulse current?
The SMCG130CA-E3/9AT has a maximum clamping voltage (VC) of 209 V when subjected to its specified peak pulse current (IPPM) of 7.2 A under the 10/1000 µs waveform condition. This value is measured per ANSI/IEEE C62.35 and ensures downstream circuitry remains within safe voltage limits during surge events. The SMCG130CA-E3/9AT achieves this with low incremental surge resistance, minimizing overshoot beyond VC.
Is SMCG130CA-E3/9AT suitable for automotive applications?
Yes, the SMCG130CA-E3/9AT is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments with operating junction temperatures up to +150 °C. Its bidirectional architecture, 1500 W surge rating, and MSL Level 1 reflow compatibility make it appropriate for protecting CAN/LIN buses, sensor inputs, and power distribution nodes in modern ECU designs. The SMCG130CA-E3/9AT meets requirements for ISO 7637-2 and ISO 16750-2 compliance when applied per Vishay's recommended layout.
What does the "CA" suffix indicate in SMCG130CA-E3/9AT?
The "CA" suffix in SMCG130CA-E3/9AT denotes a bidirectional transient voltage suppressor configuration, meaning the device provides symmetrical clamping in both polarities without cathode/anode orientation constraints. Unlike unidirectional variants (e.g., SMCG130A), the CA version has no polarity marking and functions identically regardless of voltage polarity-critical for AC-coupled or floating signal lines. This is confirmed in Vishay's documentation, which states "for bidirectional devices use CA suffix" and specifies identical VBR min/max in both directions.
What is the thermal resistance of SMCG130CA-E3/9AT, and how does it affect layout?
The SMCG130CA-E3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead (RθJL) of 15 °C/W, measured on the minimum recommended 8.0 mm × 8.0 mm copper pad per terminal. To achieve these values, PCB layout must use full-size thermal pads with multiple vias to internal ground planes. Deviating from this layout increases RθJA, reducing safe surge repetition rate and risking thermal runaway during multi-pulse events. The SMCG130CA-E3/9AT's low RθJA enables sustained operation in high-temperature enclosures without derating.
How does SMCG130CA-E3/9AT differ from SMCG130A?
The SMCG130CA-E3/9AT is bidirectional, while SMCG130A is unidirectional-meaning the latter requires correct polarity placement (cathode band toward positive rail) and conducts only in reverse bias. The CA version eliminates polarity dependency, supports AC signals, and exhibits identical electrical characteristics in both directions (VBR, VC, ID). Additionally, SMCG130CA-E3/9AT omits the cathode band marking per Vishay's mechanical data, whereas SMCG130A includes it. Both share the same SMCG (DO-215AB) package, 130 V VWM, and 1500 W PPPM rating.
