Product details
Overview
SMCG10A-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 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V clamping voltage (VC) at 88.2 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 SMCG10A-E3/57T datasheet, SMCG10A-E3/57T pinout, SMCG10A-E3/57T application, or SMCG10A-E3/57T equivalent, key selection criteria include clamping performance under 88.2 A surge, unidirectional polarity with cathode band marking, AEC-Q101 qualification for automotive use, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (11.1–12.3 V), it avalanches to limit transient energy, clamping to ≤17.0 V at 88.2 A. Its glass-passivated junction ensures stable leakage (<5.0 µA at VWM) and fast response (<1 ns), while the DO-215AB package delivers low thermal resistance (RθJL = 15 °C/W) for reliable surge dissipation.
Designed for unidirectional operation only, SMCG10A-E3/57T supports peak forward surge current (IFSM) up to 200 A (8.3 ms half-sine), complies with UL 497B (QVGQ2 recognition), and meets JESD201 Class 2 whisker resistance - making it suitable for high-reliability 12 V automotive supply rail protection where polarity-aware clamping is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 11.1 V / 12.3 V at 1 mA - defines precise avalanche onset threshold for predictable protection timing |
| VC @ IPPM | 17.0 V at 88.2 A - clamping voltage during 10/1000 µs surge, ensuring downstream ICs see <17 V stress |
| PPPM | 1500 W - peak transient power handling capability under standardized surge waveform |
| ID @ VWM | ≤5.0 µA - ultra-low leakage preserves signal integrity and minimizes standby power loss |
| TJ max | +150 °C - extended junction temperature rating enables under-hood automotive deployment |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
SMCG10A-E3/57T uses the SMCG (DO-215AB) surface-mount package: gull-wing leads, matte tin-plated terminals solderable per J-STD-002, 0.220–0.245 inch body length, and polarity indicated by a cathode band on the anode-end side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to system ground in standard unidirectional TVS configuration | Provides low-impedance path to ground during transient clamping; requires PCB trace routing to low-inductance ground plane |
| Cathode | Current exit point in forward bias; marked with band; connected to protected line (e.g., 12 V rail) | Defines polarity-sensitive connection - reverse connection disables protection and risks device failure |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control, ADAS sensors, and infotainment power supplies |
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity stress |
| MSL Level 1 (260 °C peak) | Enables single-reflow SMT assembly without moisture sensitivity concerns or baking requirements |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients, improving clamping precision for sub-100 ns spikes |
| UL 497B recognized (QVGQ2) | Meets telecom and industrial safety standards for primary-side surge protection in certified equipment |
Applications
| Automotive Power Rail Protection | 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 |
|---|---|---|---|
| SMAJ10A | Same VWM (10 V), lower PPPM (400 W), SMA (DO-214AC) package - smaller footprint but higher RθJA (110 °C/W) | Lower surge capacity limits use to consumer-grade, non-automotive applications with milder transients | Select SMAJ10A only when board space is constrained and peak surge energy is <400 W; not AEC-Q101 qualified |
| 1.5KE10A | Higher VWM (10 V), same VBR range, axial leaded (DO-201AD) package, 1500 W rating - no SMT compatibility | Requires through-hole assembly and manual rework; unsuitable for high-volume automated production | Choose 1.5KE10A only for prototyping or legacy through-hole designs; lacks MSL Level 1 and AEC-Q101 validation |
Compared with SMAJ10A and 1.5KE10A, SMCG10A-E3/57T uniquely combines AEC-Q101 qualification, DO-215AB SMT compatibility, 1500 W surge rating, and UL 497B recognition - making it the only option qualified for volume automotive production with zero layout redesign.

FAQ
What is the clamping voltage of SMCG10A-E3/57T at its rated peak pulse current?
The clamping voltage (VC) of SMCG10A-E3/57T is 17.0 V when subjected to its specified peak pulse current (IPPM) of 88.2 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures protected circuits remain below critical voltage thresholds during surge events. SMCG10A-E3/57T maintains this clamping performance across its full operating temperature range.
Is SMCG10A-E3/57T suitable for automotive applications?
Yes, SMCG10A-E3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including engine control, body electronics, and ADAS subsystems. Its construction - glass-passivated junction, MSL Level 1 rating, and UL 497B recognition - meets stringent automotive reliability requirements. SMCG10A-E3/57T is designed to withstand under-hood thermal cycling and load-dump transients without degradation.
What does the "E3/57T" suffix indicate in SMCG10A-E3/57T?
The "E3" suffix denotes RoHS-compliant, industrial-grade construction with matte tin-plated leads meeting JESD201 Class 2 whisker resistance. The "57T" indicates packaging in 7-inch plastic tape-and-reel format with 850 units per reel - optimized for high-speed pick-and-place assembly. SMCG10A-E3/57T is not halogen-free or AEC-Q101 qualified in this variant (HE3/HM3 variants carry those qualifications).
How does SMCG10A-E3/57T differ from bidirectional versions like SMCG10CA?
SMCG10A-E3/57T is unidirectional with cathode-band polarity marking and supports forward conduction; SMCG10CA is bidirectional with no polarity marking and symmetrical clamping in both directions. SMCG10A-E3/57T has IFSM = 200 A (8.3 ms) and VF = 3.5 V at 100 A, whereas SMCG10CA lacks forward surge rating. SMCG10A-E3/57T is used where polarity is known and ground-referenced protection is needed.
What is the thermal resistance from junction to ambient for SMCG10A-E3/57T?
The typical junction-to-ambient thermal resistance (RθJA) of SMCG10A-E3/57T is 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal - matching the test condition defined in the Vishay datasheet. This value assumes standard PCB layout; actual RθJA improves with larger copper areas or internal layers. SMCG10A-E3/57T also offers RθJL = 15 °C/W for direct lead-to-heat-sink coupling.
