Product details
Overview
SMCG6.0HE3/9AT from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) in the DO-215AB (SMCG) package, designed for clamping voltage transients on signal or power lines. It features a 6.0 V stand-off voltage (VWM), 1500 W peak pulse power (PPPM), and clamps to ≤10.3 V at 145.6 A (10/1000 µs waveform), making it suitable for automotive sensor line protection per AEC-Q101.
For engineers reviewing the SMCG6.0HE3/9AT datasheet, SMCG6.0HE3/9AT pinout, SMCG6.0HE3/9AT application, or SMCG6.0HE3/9AT equivalent, key selection criteria include bi-directional clamping capability, MSL Level 1 moisture sensitivity, RoHS-compliant matte tin terminations, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a bi-directional avalanche diode, leveraging glass-passivated junction technology for stable breakdown behavior under repetitive transients. Its symmetrical V-I characteristic enables suppression of both positive and negative polarity surges without polarity marking.
Designed for surface-mount use on 8.0 mm × 8.0 mm copper pads, it delivers 1500 W peak pulse power with low incremental surge resistance and fast response time - critical for protecting MOSFET gates, microcontroller I/O, and CAN/LIN bus interfaces against inductive switching and ESD events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 6.0 V - Maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown. |
| VBR (Breakdown Voltage) | 6.67–7.37 V at 10 mA - Ensures reliable turn-on during overvoltage events while avoiding false triggering. |
| VC (Clamping Voltage) | ≤10.3 V at IPPM = 145.6 A (10/1000 µs) - Limits downstream voltage stress to safe levels for 3.3 V/5 V logic interfaces. |
| PPPM (Peak Pulse Power) | 1500 W - Sustains high-energy transients such as ISO 7637-2 Pulse 1/2a/5a without degradation. |
| ID (Leakage Current) | ≤1000 µA at VWM - Minimizes standby power loss and avoids interference in high-impedance sensor circuits. |
| TJ max. | 150 °C - Enables operation in under-hood automotive environments with extended thermal margin. |
Pinout & Package
DO-215AB (SMCG) surface-mount package with gull-wing leads; no polarity marking for bi-directional operation; matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Bi-directional terminals - either lead serves as input/output; no cathode band marking required. |
| Lead 1 / Lead 2 | PCB connection interface | Gull-wing geometry supports automated placement and reflow soldering; 0.024" (0.61 mm) lead width ensures mechanical robustness. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics with lifetime reliability under thermal cycling and humidity exposure. |
| MSL Level 1 rating | Allows unlimited floor life and reflow at peak temperature up to 260 °C without preconditioning - simplifies SMT manufacturing flow. |
| Glass-passivated junction | Provides stable breakdown voltage over time and temperature, minimizing parameter drift in harsh industrial environments. |
| Low incremental surge resistance | Enables tighter clamping (VC − VBR) and higher energy absorption efficiency compared to standard TVS diodes in same package. |

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 | Uni-directional; 6.0 V VWM; SMA package (DO-214AC); lower PPPM (400 W). | Requires polarity-aware layout; unsuitable for AC-coupled or differential lines without external biasing. | Select only if unidirectional clamping suffices and board space constraints favor smaller SMA footprint. |
| 1.5KE6.8CA | Through-hole; 6.8 V VWM; DO-201 package; 1500 W PPPM; higher VC (11.5 V). | Larger footprint and manual assembly; less suitable for high-density automotive PCBs. | Prefer for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with SMAJ6.0A-E3/57T and 1.5KE6.8CA, the SMCG6.0HE3/9AT offers bi-directional symmetry in a compact, AEC-Q101-qualified surface-mount package - delivering optimal fit for modern automotive and industrial PCBs requiring zero-polarity-layout flexibility and high-reliability surge immunity.

FAQ
What is the clamping voltage of the SMCG6.0HE3/9AT at its rated peak pulse current?
The SMCG6.0HE3/9AT clamps to a maximum of 10.3 V at its rated peak pulse current (IPPM) of 145.6 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for downstream 5 V logic circuits. The SMCG6.0HE3/9AT achieves this performance with low incremental surge resistance, contributing to tight clamping margin relative to its 6.0 V stand-off voltage.
Is the SMCG6.0HE3/9AT suitable for automotive applications?
Yes, the SMCG6.0HE3/9AT is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its 150 °C maximum junction temperature, MSL Level 1 rating, and RoHS-compliant matte tin terminations meet stringent OEM requirements. The SMCG6.0HE3/9AT is commonly deployed in engine control modules, body control units, and sensor interfaces where reliability under thermal cycling and humidity is mandatory.
Does the SMCG6.0HE3/9AT have polarity markings on the package?
No, the SMCG6.0HE3/9AT does not feature polarity markings because it is a bi-directional TVS diode. The DO-215AB (SMCG) package has symmetrical terminals - either lead functions identically as anode or cathode depending on transient polarity. This eliminates orientation concerns during automated placement and simplifies layout for differential or AC-coupled signal lines.
What is the maximum leakage current specification for the SMCG6.0HE3/9AT at its stand-off voltage?
The SMCG6.0HE3/9AT exhibits a maximum reverse leakage current (ID) of 1000 µA at its 6.0 V stand-off voltage (VWM) and 25 °C ambient temperature. This low leakage preserves signal integrity in high-impedance sensor circuits and minimizes standby power draw in battery-operated automotive modules. The SMCG6.0HE3/9AT maintains this specification across its full operating temperature range per the published derating curve.
How does the SMCG6.0HE3/9AT compare to uni-directional TVS diodes like SMAJ6.0A in circuit implementation?
The SMCG6.0HE3/9AT eliminates the need for polarity-aware routing or external biasing networks required by uni-directional devices like SMAJ6.0A. Its bi-directional architecture allows direct placement across differential buses (e.g., CAN, LIN) or AC-coupled analog paths without risk of reverse-bias failure. The SMCG6.0HE3/9AT also provides identical clamping performance for both polarities - a critical advantage in unpredictable surge environments such as automotive load dump scenarios.
