Product details
Overview
SMCG6.0A-E3/9AT from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor (TVS) in the SMCG (DO-215AB) package, with 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 1500 W peak pulse power (PPPM), and clamping voltage of 10.3 V at 145.6 A IPPM. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients in automotive and industrial power electronics.
For engineers reviewing the SMCG6.0A-E3/9AT datasheet, SMCG6.0A-E3/9AT pinout, SMCG6.0A-E3/9AT application, or SMCG6.0A-E3/9AT equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), polarity marking (cathode band), and RoHS-compliant E3 suffix packaging for production-grade design-in.
Technical Context
The SMCG6.0A-E3/9AT operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve sub-nanosecond response time and low incremental surge resistance. Its 10/1000 μs waveform rating supports high-energy transient suppression without thermal runaway under repetitive surge conditions.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it meets J-STD-020 MSL Level 1 (260 °C peak reflow) and JESD201 Class 2 whisker resistance. The cathode-band polarity marking enables automated optical inspection and ensures correct orientation during PCB placement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; sets system-level overvoltage trip threshold. |
| VBR min/max | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown range ensures reliable turn-on margin above VWM for robust transient detection. |
| VC @ IPPM | 10.3 V at 145.6 A - Clamping voltage limits downstream device stress during 1500 W surge events. |
| PPPM | 1500 W - Peak pulse power handling capacity for 10/1000 μs transients, critical for automotive load-dump immunity. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance measured on standard 8 mm × 8 mm pads; informs heatsinking requirements. |
| TJ max | +150 °C - Maximum junction temperature rating enables operation in under-hood automotive environments. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
Pinout & Package
Package: SMCG (DO-215AB) - low-profile, gull-wing surface-mount case with matte tin-plated leads solderable per J-STD-002 and JESD22-B102; meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry (unidirectional) | Connected to protected circuit ground or low-side return path; must be routed with low-inductance trace. |
| Cathode | Reverse-biased terminal (marked with band) | Connected to line/voltage rail being protected; band orientation confirms polarity during AOI and manual inspection. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a). |
| AEC-Q101 qualification | Validates suitability for automotive powertrain, body control, and ADAS modules requiring zero-failure field performance. |
| MSL Level 1 rating | Supports single-reflow assembly without moisture sensitivity concerns, eliminating bake-out steps in SMT line. |
| RoHS-compliant E3 suffix | Meets industrial-grade environmental compliance with matte tin plating and halogen-free molding compound. |
Applications

IC Role / Device Role / Timing Role: Final-stage clamp on regulated 5 V/9 V/12 V outputs to protect connected devices during abnormal line conditions. Use Value: 1500 W PPPM rating exceeds IEC 61000-4-5 Level 3 (1 kV/2 Ω) requirement with safety margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-E3/57T | Same VWM/VBR/PPPM specs but in SMA (DO-214AC) package; RθJA = 85 °C/W vs. 75 °C/W; lower power derating above 25 °C. | Less thermal margin in high-density layouts; suitable where board space permits larger footprint and airflow is limited. | Select SMAJ6.0A-E3/57T only if DO-215AB footprint is unavailable and thermal budget allows higher junction rise. |
| SMCJ6.0A-E3/9AT | Higher PPPM (3000 W), same VWM/VBR, identical SMCG (DO-215AB) package; requires larger pad layout per Vishay spec (10 mm × 10 mm vs. 8 mm × 8 mm). | Overqualified for 1500 W needs; adds cost and layout overhead unless future-proofing for higher surge classes is required. | Choose SMCJ6.0A-E3/9AT only when designing for ISO 7637-2 Pulse 5a (load dump) with >200 V spikes and sustained energy demands. |
Compared with SMAJ6.0A-E3/57T and SMCJ6.0A-E3/9AT, the SMCG6.0A-E3/9AT delivers optimal balance of thermal performance (75 °C/W), compact DO-215AB footprint, and precise 6.0 V stand-off for automotive and industrial 5 V–12 V systems without over-engineering.

FAQ
What is the clamping voltage of the SMCG6.0A-E3/9AT at its rated peak pulse current?
The SMCG6.0A-E3/9AT has a maximum clamping voltage (VC) of 10.3 V at its specified peak pulse current (IPPM) of 145.6 A, measured under the standard 10/1000 μs waveform. This value is critical for ensuring downstream components like microcontrollers or gate drivers remain within safe operating voltage limits during surge events. The SMCG6.0A-E3/9AT achieves this clamping performance while maintaining low incremental surge resistance and fast response time.
Is the SMCG6.0A-E3/9AT qualified for automotive applications?
Yes, the SMCG6.0A-E3/9AT carries AEC-Q101 qualification, confirming its reliability for automotive use cases including engine control units, body electronics, and ADAS sensors. This qualification covers stress tests such as temperature cycling, high-temperature reverse bias, and ESD per JESD22-A114. The SMCG6.0A-E3/9AT's glass-passivated junction and MSL Level 1 reflow rating further support robust manufacturing and field performance in automotive environments.
What does the "E3/9AT" suffix indicate in SMCG6.0A-E3/9AT?
The "E3" suffix denotes RoHS-compliant, industrial-grade construction with matte tin-plated leads and halogen-free molding compound, while "9AT" specifies packaging in a 13-inch diameter plastic tape and reel containing 3500 units. This format supports high-volume SMT assembly with automated pick-and-place equipment. The SMCG6.0A-E3/9AT's E3 designation also confirms compliance with JESD201 Class 2 whisker resistance testing, ensuring long-term solder joint integrity.
How does the SMCG6.0A-E3/9AT differ from bidirectional variants like SMCG6.0CA?
The SMCG6.0A-E3/9AT is unidirectional, featuring a cathode band for polarity identification and conducting forward current only from anode to cathode, whereas SMCG6.0CA is bidirectional with symmetrical breakdown in both directions and no polarity marking. The SMCG6.0A-E3/9AT offers lower leakage at VWM (1000 μA max) compared to SMCG6.0CA (2000 μA max for VWM ≤10 V), making it preferred for DC rail protection where reverse conduction must be blocked. Both share the same SMCG (DO-215AB) package and 1500 W PPPM rating.
What is the thermal resistance of the SMCG6.0A-E3/9AT, and how does it affect layout design?
The SMCG6.0A-E3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. This value assumes minimum recommended pad layout per Vishay's datasheet; reducing pad size increases thermal resistance and risks exceeding TJ max = +150 °C during repeated surges. Layouts must maintain full copper fill under both terminals and avoid thermal isolation. The SMCG6.0A-E3/9AT's RθJA enables effective heat dissipation without additional heatsinking in most automotive and industrial applications.
