Product details
Overview
SMCG160A-E3/9AT from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMCG (DO-215AB) package, featuring a 160 V standoff voltage (VWM), 178–197 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (10/1000 µs), 5.8 A maximum clamping current (IPPM), and 259 V clamping voltage (VC). It protects automotive-grade power rails and signal lines against ESD and load-dump transients.
For engineers reviewing the SMCG160A-E3/9AT datasheet, SMCG160A-E3/9AT pinout, SMCG160A-E3/9AT application, or SMCG160A-E3/9AT equivalent, this device is selected for high-energy transient suppression in AEC-Q101-qualified systems where low clamping ratio, MSL Level 1 reliability, and 150 °C junction operation are required.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its specified VBR range (178–197 V). Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), enabling effective suppression of fast-rising transients such as ISO 7637-2 pulse 1 and pulse 2b.
The device is rated for 200 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), supports 6.5 W steady-state power dissipation at TA = 50 °C, and exhibits a thermal resistance of 75 °C/W (junction-to-ambient) on standard 8.0 mm × 8.0 mm copper pads - critical for thermal design in compact automotive PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 160 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin below system rail. |
| VBR (Breakdown Voltage) | 178–197 V at IT = 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 259 V at IPPM = 5.8 A - Peak voltage seen by protected circuit during 10/1000 µs transient; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 1500 W - Energy-handling capability under standardized 10/1000 µs waveform; validates robustness against ISO 16750-2 load dump. |
| TJ max. | +150 °C - Maximum junction temperature rating; enables use in under-hood automotive environments without derating. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronic modules per stress test requirements including HTGB, HTRB, and TCT. |
| Package | SMCG (DO-215AB) - Low-profile SMD outline with gull-wing leads; compatible with automated placement and reflow soldering (MSL Level 1, 260 °C peak). |
Pinout & Package
SMCG160A-E3/9AT uses the SMCG (DO-215AB) surface-mount package: a dual-leaded, gull-wing configuration with cathode band marking on the anode-side end cap. Leads are matte tin-plated and solderable per J-STD-002/JESD 22-B102. Polarity is unidirectional - the marked band denotes the cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to ground or lower-potential node in unidirectional TVS configuration. | Provides low-impedance path to ground during clamping; must be routed with minimal inductance to preserve response speed. |
| Cathode | Current exit point in forward bias; connected to protected line (e.g., 12 V battery rail or CAN-H). | Carries full transient current during clamping; requires direct connection to protected net and adequate copper area for heat dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure. |
| AEC-Q101 qualification | Validates suitability for automotive powertrain, body control, and ADAS modules without additional qualification effort. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients, improving protection margin for downstream MOSFETs and ICs. |
| MSL Level 1 rating | Enables standard reflow assembly without baking or special handling - reduces manufacturing cost and risk. |
| UL 94 V-0 molding compound | Meets flammability safety requirements for enclosed automotive and industrial enclosures. |
Applications

Use Scenario: Protects high-side gate driver ICs (e.g., ISO5852S) from Miller-induced voltage spikes during IGBT/MOSFET switching. IC Role / Device Role / Timing Role: Clamp across gate-source terminals or bootstrap supply rail to suppress dv/dt-induced ringing. Use Value: Fast response and low clamping voltage prevent false turn-on and gate oxide overstress in 650 V+ power stages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-E3/57T | Same VWM (160 V) and PPPM (400 W), but lower power rating and SMA (DO-214AC) package. | Limited to lower-energy transients (e.g., ESD only); not suitable for load-dump or ISO 7637-2 pulse 5a. | Select when board space is constrained and surge energy is ≤400 W - avoids overdesign and cost premium of SMCG. |
| SMCJ160A-E3/9AT | Same VWM and clamping performance, but SMC (DO-214AB) package with higher thermal mass and 1500 W rating. | Better thermal performance on minimal copper; preferred for high-volume industrial designs with manual rework constraints. | Choose when legacy SMC footprint exists or when RθJA <75 °C/W is required without enlarging pad layout. |
Compared with SMAJ160A-E3/57T and SMCJ160A-E3/9AT, SMCG160A-E3/9AT delivers identical electrical protection in a lower-profile, AEC-Q101-qualified DO-215AB package - optimizing for automated assembly, under-hood automotive use, and space-constrained PCBs without sacrificing 1500 W surge capability.

FAQ
What is the clamping voltage of SMCG160A-E3/9AT at its rated peak pulse current?
The SMCG160A-E3/9AT has a maximum clamping voltage (VC) of 259 V at its specified peak pulse current (IPPM) of 5.8 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuits during standardized surge events - critical for ensuring downstream components remain within their absolute maximum ratings.
Is SMCG160A-E3/9AT qualified for automotive applications?
Yes, SMCG160A-E3/9AT is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), temperature cycling (TCT), and unbiased highly accelerated stress testing (UHAST). This qualification confirms its suitability for under-hood and chassis-mounted automotive modules where reliability under thermal and mechanical stress is mandatory.
What does the "E3/9AT" suffix indicate in SMCG160A-E3/9AT?
The "E3" suffix denotes RoHS-compliant, industrial-grade construction with matte tin-plated leads; "9AT" specifies packaging in 13-inch diameter plastic tape and reel with a base quantity of 3500 units. This format supports high-speed automated pick-and-place assembly and aligns with IPC-7351B land pattern recommendations for the DO-215AB outline.
How does SMCG160A-E3/9AT differ from bidirectional variants like SMCG160CA?
SMCG160A-E3/9AT is unidirectional and features a cathode band marking, whereas SMCG160CA is bidirectional with no polarity marking and symmetric breakdown in both directions. The unidirectional version offers lower leakage current and is preferred for DC rail protection (e.g., 12 V battery), while the CA variant suits AC-coupled or differential signal lines where polarity reversal occurs.
What thermal design guidance applies to SMCG160A-E3/9AT in high-power transient scenarios?
SMCG160A-E3/9AT has a typical RθJA of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. For repeated 1500 W transients, designers must ensure junction temperature remains ≤150 °C by verifying ambient temperature, pad copper weight, and adjacent heat sources. Derating curves in Figure 2 of the datasheet (Doc. #88457) must be applied above TA = 25 °C.
