Product details
Overview
SMCG100A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for high-energy surge protection with 100 V standoff voltage (VWM), 111–123 V breakdown voltage (VBR), and 1500 W peak pulse power (PPPM) at 10/1000 μs. It clamps transients to ≤162 V at 9.3 A peak pulse current and operates across –55 °C to +150 °C junction temperature, targeting automotive and industrial power rail protection.
For engineers reviewing the SMCG100A-E3/57T datasheet, SMCG100A-E3/57T pinout, SMCG100A-E3/57T application, or SMCG100A-E3/57T equivalent, this device delivers AEC-Q101 qualified transient suppression for 12 V/24 V automotive systems, DC power supplies, and sensor interface lines where low clamping voltage, fast response, and robust surge handling are critical.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for bidirectional-capable unidirectional operation, with polarity indicated by a cathode band. Its low incremental surge resistance enables tight clamping under high-current transients, while MSL Level 1 moisture sensitivity supports lead-free reflow up to 260 °C peak.
The device meets UL 497B recognition (QVGQ2) and complies with ANSI/IEEE C62.35 surge standards. Thermal resistance is 75 °C/W (junction-to-ambient) on standard 8.0 mm × 8.0 mm copper pads, enabling reliable power dissipation of 6.5 W at TA = 50 °C without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - Maximum continuous reverse operating voltage before clamping begins; sets system-level overvoltage threshold for 12 V/24 V automotive rails. |
| VBR (min/max) | 111 V / 123 V at 1 mA - Confirmed breakdown range ensures predictable turn-on during surges; guarantees clamping activation above normal operating voltage. |
| VC @ IPPM | ≤162 V at 9.3 A - Clamped voltage under 10/1000 μs surge; defines worst-case stress on downstream ICs or MOSFETs during lightning or load-dump events. |
| PPPM | 1500 W - Peak pulse power rating per 10/1000 μs waveform; validates capability to absorb ISO 7637-2 Pulse 5a/b energy without failure. |
| TJ max. | +150 °C - Maximum junction temperature; supports under-hood automotive placement and extended thermal margin in industrial enclosures. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance on standard PCB pad layout; enables accurate thermal design without forced cooling. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; required for engine control, ADAS, and body electronics. |
Pinout & Package
Package: SMCG (DO-215AB) - Surface-mount gull-wing package with matte tin-plated leads, 0.220–0.245 inch body length, and 0.115–0.125 inch lead span. Complies with J-STD-002 solderability and JESD22-B102 whisker testing (Class 2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to protected circuit ground or low-side return path. | Provides low-resistance path for surge current to ground when reverse-biased; must be routed with minimal inductance to maintain clamping performance. |
| Cathode | Current exit terminal in forward bias; marked with band; connected to protected line (e.g., battery rail or signal line). | Defines polarity-sensitive connection point; incorrect orientation disables protection and risks catastrophic failure during surge events. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR over lifetime and temperature; eliminates parameter drift due to humidity or contamination in harsh environments. |
| Low-profile DO-215AB package | Enables automated SMT placement and high-density PCB layouts; compatible with standard 7" tape-and-reel (57T) feeding equipment. |
| 1500 W peak pulse power | Handles ISO 16750-2 load-dump surges (up to 120 V, 100 ms) and IEC 61000-4-5 combination wave (1.2/50 μs + 8/20 μs) without degradation. |
| AEC-Q101 qualification | Validates suitability for automotive applications requiring zero-defect reliability, including engine management, infotainment, and lighting modules. |
| UL 497B recognition (QVGQ2) | Confirms compliance with telecom and industrial surge protector safety standards; simplifies end-equipment certification. |

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). | Lower surge capacity limits use to consumer or non-automotive industrial applications; not AEC-Q101 qualified. | Select when cost or board space is prioritized over automotive-grade surge rating and thermal performance. |
| SMCJ100A-E3/57T | Same VWM (100 V), higher PPPM (1500 W), but larger SMC (DO-214AB) package and higher RθJA (50 °C/W on same pad). | Requires more PCB area; better suited for high-temperature ambient designs needing higher derated power at elevated TA. | Choose when thermal budget allows larger footprint and higher sustained power dissipation is needed beyond 6.5 W. |
Compared with SMCG100A-E3/57T, SMAJ100A-E3/57T offers reduced surge capability and no automotive qualification, while SMCJ100A-E3/57T trades compact DO-215AB size for greater thermal mass-making SMCG100A-E3/57T optimal for space-constrained AEC-Q101 designs demanding full 1500 W rating in minimal footprint.

FAQ
What is the maximum clamping voltage of the SMCG100A-E3/57T under a 10/1000 μs surge?
The SMCG100A-E3/57T 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 per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuits during surge events, ensuring downstream components remain within safe operating margins.
Is the SMCG100A-E3/57T suitable for automotive applications?
Yes, the SMCG100A-E3/57T is AEC-Q101 qualified and UL 497B recognized (QVGQ2), making it suitable for automotive powertrain, body electronics, and ADAS modules. Its –55 °C to +150 °C operating range, glass-passivated junction, and 1500 W surge rating meet stringent requirements for under-hood and chassis-mounted systems.
What does the "E3/57T" suffix indicate in SMCG100A-E3/57T?
The "E3" suffix denotes RoHS-compliant, industrial-grade construction with matte tin-plated leads; "57T" specifies packaging in 7-inch diameter plastic tape and reel containing 850 units. This configuration supports automated SMT assembly and aligns with J-STD-002 solderability and JESD22-B102 whisker testing Class 2 requirements.
How does the SMCG100A-E3/57T differ from bidirectional variants like SMCG100CA?
The SMCG100A-E3/57T is unidirectional with cathode-band polarity marking and conducts only in reverse bias, whereas SMCG100CA is bidirectional with symmetrical clamping in both directions and no polarity marking. The unidirectional version provides lower leakage and tighter VBR tolerance, ideal for DC rail protection where polarity is fixed.
What is the thermal resistance of the SMCG100A-E3/57T on standard PCB pads?
The SMCG100A-E3/57T 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 value is measured per JEDEC standards and enables accurate thermal modeling for power dissipation up to 6.5 W at TA = 50 °C without additional heatsinking.
