Product details
Overview
SMCG5.0A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor (TVS) diode in DO-215AB (SMCG) package, designed for clamping ESD and surge transients on power and signal lines. It features 5.0 V stand-off voltage (VWM), 6.40–7.07 V breakdown voltage (VBR) at 10 mA, 1500 W peak pulse power (10/1000 µs), 163 A peak pulse current (IPPM), and 9.20 V maximum clamping voltage (VC) - optimized for protecting 5 V logic rails, USB interfaces, and automotive sensor inputs.
For engineers reviewing the SMCG5.0A-E3/57T datasheet, SMCG5.0A-E3/57T pinout, SMCG5.0A-E3/57T application, or SMCG5.0A-E3/57T equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, MSL Level 1 rating, 75 °C/W junction-to-ambient thermal resistance, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamping protection device in series with sensitive downstream ICs. Its glass-passivated silicon junction enables sub-nanosecond response to transients, while low incremental surge resistance ensures stable clamping under high-current surges up to 163 A (10/1000 µs).
The SMCG5.0A-E3/57T is rated for -55 °C to +150 °C operating junction temperature, supports 200 A non-repetitive forward surge (8.3 ms half-sine), and meets UL 497B recognition (QVGQ2) and JESD201 Class 2 whisker resistance - confirming suitability for automotive and industrial environments requiring robust reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - maximum continuous reverse working voltage; defines safe operating threshold before clamping begins on 5 V supply rails. |
| VBR (min/max) | 6.40 V / 7.07 V at 10 mA - guaranteed breakdown range ensures reliable turn-on margin above VWM without premature conduction. |
| VC @ IPPM | 9.20 V at 163 A - clamping voltage during worst-case surge; limits stress on protected 5 V ICs to <9.2 V peak. |
| PPPM | 1500 W (10/1000 µs) - peak transient energy handling capacity; supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when properly laid out. |
| RθJA | 75 °C/W - junction-to-ambient thermal resistance on standard 8.0 mm × 8.0 mm pads; enables thermal design for 6.5 W steady-state dissipation at TA = 50 °C. |
| TJ max. | +150 °C - maximum junction temperature; validated for under-hood automotive use and extended industrial temperature operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A-E3/57T | Same VWM (5.0 V) and VC (9.2 V), but lower PPPM (400 W) and smaller SMA package (DO-214AC); RθJA = 110 °C/W. | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 or automotive load-dump scenarios. | Select when board space is constrained and surge threat level is limited to ESD or low-energy switching noise. |
| SMCJ5.0A-E3/57T | Same DO-214AB package footprint but higher VBR (6.7–7.4 V), same PPPM (1500 W); not AEC-Q101 qualified. | Lacks automotive qualification and UL 497B recognition; thermal resistance slightly higher (RθJA = 80 °C/W). | Choose for industrial-only designs where AEC-Q101 is not required and cost optimization is prioritized. |

FAQ
What is the clamping voltage of SMCG5.0A-E3/57T at its rated peak pulse current?
The SMCG5.0A-E3/57T has a maximum clamping voltage (VC) of 9.20 V at its rated peak pulse current (IPPM) of 163 A under the standard 10/1000 µs waveform. This value is measured with the device mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per the Vishay datasheet, ensuring realistic thermal and electrical conditions for design validation.
Is SMCG5.0A-E3/57T suitable for automotive applications?
Yes, SMCG5.0A-E3/57T is AEC-Q101 qualified and UL 497B recognized (file E136766), making it suitable for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its -55 °C to +150 °C operating range and qualification testing cover under-hood and cabin-mounted use cases.
What does the "E3/57T" suffix indicate in SMCG5.0A-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 with 850 units per reel. This format supports automated SMT placement and complies with JESD201 Class 2 whisker resistance requirements.
How does SMCG5.0A-E3/57T differ from bidirectional variants like SMCG5.0CA?
SMCG5.0A-E3/57T is unidirectional with cathode marking and forward conduction capability, while SMCG5.0CA is bidirectional with no polarity marking and symmetric clamping in both directions. The unidirectional version supports higher IFSM (200 A) and is preferred for DC power rail protection; the bidirectional variant suits AC-coupled signal lines.
What PCB layout guidance applies to SMCG5.0A-E3/57T for optimal surge performance?
For optimal transient suppression, SMCG5.0A-E3/57T must be mounted on minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, with short, low-inductance traces to ground. Thermal vias under pads and solid ground planes are recommended to maintain RθJA ≤ 75 °C/W and sustain 1500 W peak pulse power without junction overheating.
