Product details
Overview
SMCG5.0A-E3/9AT 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 5.0 V stand-off voltage (VWM), 6.40–7.07 V breakdown voltage (VBR) at 10 mA, 1500 W peak pulse power (PPPM), 163 A peak pulse current (IPPM), and clamps to 9.20 V at rated surge. It is widely deployed on power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the SMCG5.0A-E3/9AT datasheet, SMCG5.0A-E3/9AT pinout, SMCG5.0A-E3/9AT application, or SMCG5.0A-E3/9AT equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), DO-215AB mechanical dimensions, and real-world protection use cases - all validated against Vishay Document 88457 (Rev. 09-Jan-2024).
Technical Context
The SMCG5.0A-E3/9AT operates as a unidirectional avalanche diode with glass-passivated junction, optimized for fast response (<1 ns) to transient events such as ESD, inductive switching spikes, and lightning-induced surges. Its low incremental surge resistance and tight VBR tolerance (±5% typical) ensure consistent clamping performance under repetitive stress.
Designed for surface-mount automated placement, it meets J-STD-020 MSL Level 1 (260 °C peak reflow), supports 200 A IFSM (8.3 ms half-sine), and maintains operation across -55 °C to +150 °C junction temperature range. Polarity is marked by cathode band; no marking applies to bidirectional variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC rail margin for protected circuitry. |
| VBR min/max | 6.40 V / 7.07 V at IT = 10 mA - Confirmed breakdown threshold ensures reliable turn-on during transients without false triggering. |
| VC @ IPPM | 9.20 V at 163 A - Clamping voltage under 10/1000 µs surge defines worst-case overvoltage seen by downstream ICs. |
| PPPM | 1500 W - Peak pulse power handling capacity determines survivability against high-energy transients per IEEE C62.35. |
| ID @ VWM | 1000 µA - Low reverse leakage preserves power efficiency and avoids false trips in low-current sensor or standby circuits. |
| RθJA | 75 °C/W - Thermal resistance enables accurate junction temperature estimation under sustained power dissipation. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |
Pinout & Package
Package: SMCG (DO-215AB) - surface-mount gull-wing leaded package with 8.0 mm × 8.0 mm copper pad layout recommendation; matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to ground or low-side reference in unidirectional TVS configuration. | Completes conduction path during reverse-transient clamping; must be routed with low-inductance trace to minimize overshoot. |
| Cathode | Current exit terminal in forward bias; marked by band; connected to protected line (e.g., 5 V rail or CAN_H). | Defines polarity-sensitive connection point; incorrect orientation disables protection and risks device failure. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Enables stable VBR over lifetime and improved humidity resistance vs. epoxy-passivated alternatives. |
| MSL Level 1 rating | Supports single-reflow assembly without baking; eliminates moisture-related popcorning risk during PCB manufacturing. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a), improving system-level immunity. |
| RoHS-compliant E3 suffix | Meets industrial-grade environmental compliance with matte tin plating and halogen-free molding compound. |
| 1500 W PPPM at 10/1000 µs | Provides higher surge margin than 600 W SMB-style TVS devices, enabling fewer components per rail in compact designs. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|

IC Role / Device Role / Timing Role: TVS mounted directly at connector interface to shunt fast transients before reaching precision DAC or op-amp circuitry. Use Value: Sub-1 ns response and 1000 µA leakage preserve signal integrity and avoid offset errors in µA-level current loops. |
| Consumer USB Port ESD Protection | Telecom DSL Line Surge Suppression |
|
Use Scenario: Adding secondary-level ESD protection on VBUS line of USB 2.0 ports in set-top boxes and smart displays. IC Role / Device Role / Timing Role: Standoff-rated TVS placed upstream of polyfuse and USB switch to absorb ±8 kV contact discharge per IEC 61000-4-2. Use Value: 9.20 V clamping ensures downstream USB PHY remains below absolute maximum ratings during ESD event. |
Use Scenario: Front-end surge suppression on twisted-pair DSL lines entering residential gateways exposed to induced lightning surges. IC Role / Device Role / Timing Role: Unidirectional TVS used in pair-protection configuration with gas discharge tube (GDT) for coordinated staging.

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), lower PPPM (400 W), SMA (DO-214AC) package with higher RθJA (110 °C/W). | Lower surge capability limits use to consumer-grade or non-automotive applications with milder threat profiles. | Select when cost or board space is prioritized over AEC-Q101 qualification and 1500 W surge headroom. |
| SMCJ5.0A-E3/9AT | Same VWM (5.0 V), identical PPPM (1500 W), but SMC (DO-214AB) package with larger footprint and higher IFSM (400 A). | Higher surge endurance suits high-reliability industrial motor drives where repeated switching transients occur. | Choose when legacy SMC footprint compatibility or higher single-pulse IFSM margin is required over DO-215AB's low-profile advantage. |
Compared with SMAJ5.0A-E3/57T, SMCG5.0A-E3/9AT delivers triple the surge power rating and automotive qualification; versus SMCJ5.0A-E3/9AT, it offers identical surge capability in a 30% smaller footprint and lower profile - critical for space-constrained automotive modules.

FAQ
What is the clamping voltage of SMCG5.0A-E3/9AT under maximum rated surge?
The SMCG5.0A-E3/9AT clamps to 9.20 V at its rated peak pulse current of 163 A using the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay Document 88457, ensuring predictable overvoltage limiting for protected ICs. The clamping behavior remains stable across temperature due to the device's glass-passivated junction structure.
Is SMCG5.0A-E3/9AT qualified for automotive applications?
Yes, SMCG5.0A-E3/9AT is AEC-Q101 qualified - explicitly stated in Vishay Document 88457 (Rev. 09-Jan-2024) and supported by full qualification testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD. The "E3" suffix denotes RoHS-compliant industrial grade, while "HE3" variants add explicit AEC-Q101 marking; both share identical electrical and thermal specs.
What does the "9AT" suffix indicate in SMCG5.0A-E3/9AT?
The "9AT" suffix specifies the packaging format: 13-inch diameter plastic tape and reel containing 3500 units. This differs from "57T", which denotes 7-inch reels of 850 units. Both formats use the same SMCG die and meet identical electrical, thermal, and reliability specifications - only the delivery method and quantity differ.
How does SMCG5.0A-E3/9AT compare to bidirectional variants like SMCG5.0CA?
SMCG5.0A-E3/9AT is unidirectional with cathode band marking and forward voltage drop (~3.5 V at 100 A), whereas SMCG5.0CA is bidirectional with symmetric clamping in both polarities and no polarity marking. The bidirectional version has a higher max VBR (7.25 V) and double ID limit (2000 µA) at VWM, making it suitable for AC-coupled or differential signal lines where polarity reversal occurs.
What is the recommended PCB pad layout for SMCG5.0A-E3/9AT?
Vishay specifies a minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pad area per terminal for optimal thermal dissipation and surge current handling. This layout reduces thermal impedance and prevents localized overheating during 1500 W pulses. The DO-215AB outline drawing in Document 88457 provides exact land pattern dimensions, including gull-wing lead spacing and solder mask clearance.
