Product details
Overview
SMCG5.0-E3/9AT from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) in DO-215AB (SMCG) package, designed for clamping voltage transients on signal and power lines. It features 5.0 V stand-off voltage (VWM), 1500 W peak pulse power (PPPM), 9.20 V maximum clamping voltage (VC) at 163 A IPPM, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMCG5.0-E3/9AT datasheet, SMCG5.0-E3/9AT pinout, SMCG5.0-E3/9AT application, or SMCG5.0-E3/9AT equivalent, this device is selected for robust ESD and surge protection in low-voltage sensor interfaces, automotive control modules, and industrial I/O circuits where fast response (<1 ns), low clamping, and MSL Level 1 reflow compatibility are critical.
Technical Context
This bi-directional TVS diode operates symmetrically across both polarities, with breakdown voltage (VBR) of 6.40–7.07 V at 10 mA test current and reverse leakage (ID) ≤1000 μA at 5.0 V VWM. Its glass-passivated junction ensures stable performance under repetitive surge stress and high-temperature operation up to TJ = 150 °C.
The device uses a low-inductance DO-215AB surface-mount package optimized for automated placement, with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102 solderability standards. Thermal resistance is RθJA = 75 °C/W (on 8.0 mm × 8.0 mm copper pads), enabling effective power dissipation without heatsinking in typical PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working range for 5 V logic/sensor rails. |
| PPPM | 1500 W - Peak pulse power handling with 10/1000 μs waveform; supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when properly laid out. |
| VC @ IPPM | 9.20 V - Clamped voltage at 163 A peak pulse current; limits downstream IC stress to <10 V during worst-case transients. |
| VBR min/max | 6.40 / 7.07 V - Breakdown voltage range at 10 mA; ensures tight tolerance for precise overvoltage thresholding. |
| ID @ VWM | ≤1000 μA - Reverse leakage at 5.0 V; negligible loading on low-power sensor bias networks. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments and industrial enclosures. |
| MSL Level | Level 1 (per J-STD-020) - No floor life limitation; supports standard reflow profiles up to 260 °C peak. |
Pinout & Package
SMCG5.0-E3/9AT is housed in the DO-215AB (SMCG) surface-mount package - a gull-wing leaded outline measuring 7.87 mm × 3.17 mm × 2.41 mm (L × W × H), with 2.0 mm lead pitch and matte tin-plated terminations. Bi-directional construction means no polarity marking; both terminals are functionally identical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Bi-directional clamping node - connects between protected line and ground (or rail); no cathode band marking required. |
| Lead 1 / Lead 2 | Low-inductance interface | Gull-wing terminations minimize parasitic inductance (<1 nH typical), preserving fast response (<1 ns) during ESD events. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. |
| Glass passivated junction | Ensures long-term stability of VBR and leakage under thermal cycling and humidity exposure per JESD22-A101. |
| Low incremental surge resistance | Minimizes VC rise under high di/dt surges - critical for protecting fast-switching MOSFET gates and microcontroller I/O. |
| UL 94 V-0 molding compound | Self-extinguishing encapsulation meets flame-retardancy requirements for industrial and transportation end equipment. |
| J-STD-020 MSL Level 1 | Enables single-pass reflow assembly without baking or dry-pack handling - reduces manufacturing cost and risk. |
Applications

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 | DO-214AC (SMA) package; same VWM (5.0 V), lower PPPM (400 W), higher VC (9.6 V at 43.5 A). | Lower surge rating suits consumer-grade I/O; not AEC-Q101 qualified. | Select when cost sensitivity outweighs automotive qualification and 1500 W surge headroom. |
| SMCJ5.0A-E3/9AT | DO-214AB (SMC) package; same VWM (5.0 V), identical PPPM (1500 W), slightly higher VC (9.6 V at 156 A). | Larger footprint (7.11 mm × 6.22 mm) vs. SMCG (7.87 mm × 3.17 mm); same thermal performance on equivalent pad layout. | Select when existing SMC footprint is standardized and board space permits wider package. |
Compared with SMAJ5.0A-E3/57T and SMCJ5.0A-E3/9AT, SMCG5.0-E3/9AT delivers identical 1500 W surge capability in a narrower, automotive-qualified package with tighter clamping (9.20 V) and MSL Level 1 compliance - making it optimal for space-constrained, high-reliability 5 V rail protection.

FAQ
What is the clamping voltage of SMCG5.0-E3/9AT at its rated peak pulse current?
The SMCG5.0-E3/9AT has a maximum clamping voltage (VC) of 9.20 V at its rated peak pulse current (IPPM) of 163 A, measured using the standard 10/1000 μs waveform. This value ensures protected circuits remain below critical voltage thresholds during surge events, and is confirmed in the Vishay datasheet Document Number 88457, page 2.
Is SMCG5.0-E3/9AT suitable for automotive applications?
Yes, SMCG5.0-E3/9AT is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its DO-215AB package meets MSL Level 1, and its 150 °C maximum junction temperature supports under-hood deployment - all verified in Vishay's official qualification report and datasheet revision 14-Mar-12.
Does SMCG5.0-E3/9AT have polarity markings?
No, SMCG5.0-E3/9AT is a bi-directional TVS diode and carries no polarity marking such as a cathode band. Both terminals are functionally identical, allowing flexible PCB layout without orientation constraints - a key distinction from uni-directional variants like SMCG5.0A, which feature a visible band.
What is the thermal resistance of SMCG5.0-E3/9AT?
The SMCG5.0-E3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. Its junction-to-lead resistance (RθJL) is 15 °C/W, supporting efficient heat transfer in compact layouts without external heatsinking.
How does SMCG5.0-E3/9AT differ from SMCG5.0A?
SMCG5.0-E3/9AT is the bi-directional version (suffix "CA" implied by "E3/9AT" ordering code per Vishay's documentation), while SMCG5.0A is uni-directional. The bi-directional variant has symmetric clamping in both polarities, no cathode marking, and a slightly higher ID limit (1000 μA vs. 500 μA for some uni-directional grades). Both share identical VWM, PPPM, and package.
