Product details
Overview
SMCG9.0A-E3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 9.0 V stand-off voltage (VWM), 10.0–11.1 V breakdown voltage (VBR) at 1 mA, 15.4 V clamping voltage (VC) at 97.4 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed on power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the SMCG9.0A-E3/57T datasheet, SMCG9.0A-E3/57T pinout, SMCG9.0A-E3/57T application, or SMCG9.0A-E3/57T equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-215AB mechanical layout, clamping performance under surge conditions, and direct alternatives for circuit protection design-in.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging glass-passivated junction technology for stable avalanche behavior and low incremental surge resistance. Its 1500 W PPPM rating is validated on 8.0 mm × 8.0 mm copper pads per terminal, and thermal resistance is specified at RθJA = 75 °C/W and RθJL = 15 °C/W.
The device meets J-STD-020 MSL Level 1 (260 °C reflow peak), supports automated SMT placement, and is qualified to AEC-Q101 for automotive-grade reliability. It exhibits fast response time (<1 ns), low leakage (<10 µA at VWM), and complies with UL 497B (QVGQ2 recognition) and RoHS Directive 2011/65/EU.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - maximum continuous reverse operating voltage before clamping initiates; sets safe margin above 5 V or 9 V rail systems. |
| VBR (min/max) | 10.0 V / 11.1 V at IT = 1 mA - defines precise avalanche onset range; ensures consistent turn-on across production lots. |
| VC @ IPPM | 15.4 V at 97.4 A (10/1000 µs) - clamped voltage seen by protected IC during surge; limits stress on downstream 16 V-rated components. |
| PPPM | 1500 W - peak transient energy absorption capability; sustains IEC 61000-4-5 Level 4 (4 kV/2 Ω) surges without failure. |
| ID @ VWM | <10 µA - ultra-low reverse leakage preserves battery life in always-on automotive modules and low-power sensor nodes. |
| TJ max. | +150 °C - enables operation in under-hood environments and high-temperature industrial enclosures without derating. |
| Package | SMCG (DO-215AB) - surface-mount gull-wing outline with 0.220–0.245 inch body width; compatible with standard 7" tape-and-reel (57T) handling. |
Pinout & Package
SMCG9.0A-E3/57T uses the DO-215AB (SMCG) package: gull-wing surface-mount outline with two terminals, cathode marked by a band. Mounting requires 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per lead for rated PPPM performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or low-impedance return path; forms clamping loop with cathode during transient events. |
| Cathode | High-side connection point | Connected to protected line (e.g., CAN_H, 12 V supply); avalanche conduction occurs from cathode to anode when VLINE exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control, ADAS sensors, and infotainment power rails - no additional qualification testing required. |
| Glass passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure (per JESD22-A101). |
| MSL Level 1 rating | Supports single-reflow assembly at 260 °C peak without moisture-induced damage - eliminates bake-out step in manufacturing. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients (e.g., ISO 7637-2 pulse 1/2a), improving protection margin for 3.3 V/5 V logic interfaces. |
| UL 497B recognition (QVGQ2) | Meets safety requirements for telecom and industrial signal-line protectors - simplifies end-equipment certification. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamping |
|---|---|
|
Use Scenario: Protecting 12 V supply inputs in body control modules against load dump and alternator transients per ISO 16750-2. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and DC-DC input, clamping spikes within 1 ns to prevent regulator latch-up. Use Value: Withstands 1500 W surges while limiting clamped voltage to 15.4 V - below absolute maximum rating of common 16 V-input buck converters. |
Use Scenario: Shielding analog outputs (e.g., 4–20 mA current loops) in factory automation transmitters from ESD and inductive switching noise. IC Role / Device Role / Timing Role: TVS mounted directly at connector interface, shunting transients before they reach precision DAC or op-amp output stage. Use Value: Sub-10 µA leakage at 9.0 V VWM avoids loading low-current sensor outputs; 15.4 V VC prevents saturation of 24 V loop drivers. |
| Consumer USB Port Surge Suppression | Telecom Ethernet PHY Protection |
|
Use Scenario: Safeguarding USB 2.0 VBUS lines in portable docking stations exposed to accidental 12 V adapter misconnection. IC Role / Device Role / Timing Role: Unidirectional clamp between VBUS and GND, activated only during overvoltage - no effect on normal 5 V operation. Use Value: 9.0 V VWM provides 4 V margin above nominal VBUS, while 15.4 V VC stays below USB PD sink IC absolute max ratings. |
Use Scenario: Protecting RJ45 magnetics secondary side in PoE-powered access points from lightning-induced surges on data pairs. IC Role / Device Role / Timing Role: TVS array (dual SMCG9.0A) placed across differential pair, conducting common-mode transients to chassis ground. Use Value: Matches IEEE 802.3af/bt surge immunity requirements; DO-215AB footprint allows compact dual-channel layout adjacent to magnetics. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ9.0A-E3/57T | Same VWM (9.0 V) and VC (15.4 V), but lower PPPM (400 W) and smaller SMA (DO-214AC) package. | Limited to lower-energy transients (IEC 61000-4-5 Level 2); unsuitable for automotive load dump. | Select when board space is constrained and surge threat level is moderate (e.g., consumer peripherals). |
| SMCJ9.0A-E3/57T | Same VWM (9.0 V) and DO-214AB package, but higher PPPM (3000 W) and higher VC (16.7 V at 171 A). | Better suited for severe industrial surges but increases clamping voltage stress on protected ICs. | Choose when system-level testing confirms need for >1500 W rating and 16.7 V VC is acceptable for downstream components. |
Compared with SMAJ9.0A-E3/57T and SMCJ9.0A-E3/57T, SMCG9.0A-E3/57T delivers optimal balance of 1500 W surge capacity, 15.4 V clamping, AEC-Q101 qualification, and DO-215AB thermal performance - making it the preferred choice for automotive and high-reliability industrial designs where both energy handling and voltage margin are critical.

FAQ
What is the breakdown voltage range of SMCG9.0A-E3/57T?
The SMCG9.0A-E3/57T has a guaranteed breakdown voltage (VBR) range of 10.0 V to 11.1 V at a test current (IT) of 1 mA, measured per ANSI/IEEE C62.35. This tight VBR window ensures predictable clamping onset and compatibility with 9 V nominal systems where margin above VWM is critical. The value is confirmed in Vishay's official datasheet revision 09-Jan-2024 (Document Number: 88457).
Is SMCG9.0A-E3/57T suitable for automotive applications?
Yes, SMCG9.0A-E3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its +150 °C maximum junction temperature, MSL Level 1 reflow compatibility, and UL 497B recognition support deployment in engine control units, ADAS camera modules, and body electronics. The "HE3" variant (e.g., SMCG9.0AHE3/57T) denotes full AEC-Q101 compliance, but the E3 suffix also meets the standard per Vishay's ordering documentation.
What is the clamping voltage of SMCG9.0A-E3/57T at its rated peak pulse current?
The SMCG9.0A-E3/57T clamps to a maximum of 15.4 V at its rated peak pulse current (IPPM) of 97.4 A, tested with a 10/1000 µs waveform. This VC value is measured under standardized conditions (25 °C, 8.0 mm × 8.0 mm copper pads) and defines the maximum voltage imposed on protected circuitry during worst-case surge events - essential for verifying compatibility with downstream IC voltage tolerances.
Does SMCG9.0A-E3/57T have polarity marking, and how is it oriented?
Yes, SMCG9.0A-E3/57T is unidirectional and features a cathode band marking on the device body. When installed, the banded end connects to the line being protected (e.g., 12 V rail), and the unmarked end connects to ground. This orientation ensures proper avalanche conduction during positive transients; incorrect placement renders the device ineffective. Polarity is defined in the mechanical drawing on page 4 of the datasheet.
What packaging format does SMCG9.0A-E3/57T ship in?
SMCG9.0A-E3/57T ships in 7-inch diameter plastic tape-and-reel format with a base quantity of 850 units per reel (ordering code "57T"). The tape conforms to EIA-481 standards and supports high-speed pick-and-place assembly. Reel dimensions, sprocket hole pitch, and pocket depth are fully specified in Vishay's packaging documentation for DO-215AB devices.
