Product details
Overview
SMCG10HE3/9AT from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) in DO-215AB (SMCG) package, rated for 10 V stand-off voltage (VWM), 1500 W peak pulse power (PPPM), and clamping voltage of 17.0 V at 88.2 A IPPM. It provides robust ESD and surge protection for signal lines in automotive sensor units and industrial control interfaces.
For engineers reviewing the SMCG10HE3/9AT datasheet, SMCG10HE3/9AT pinout, SMCG10HE3/9AT application, or SMCG10HE3/9AT equivalent, this AEC-Q101 qualified TVS offers validated clamping performance, low incremental surge resistance, and MSL Level 1 reflow compatibility - critical for high-reliability automotive and industrial PCB designs requiring stable transient suppression without polarity constraints.
Technical Context
This bi-directional TVS operates symmetrically in both polarities with no cathode marking, enabling simplified layout on bidirectional data or AC-coupled lines. Its glass-passivated junction ensures stable breakdown behavior across -55 °C to +150 °C operating range, and its 75 °C/W junction-to-ambient thermal resistance supports sustained 6.5 W power dissipation at TA = 50 °C.
The device meets UL 94 V-0 flammability requirements and features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance - essential for under-hood automotive electronics.
Key Specifications

Applications
| Automotive Sensor Protection | Industrial CAN Bus Interface |
|---|---|
Use Scenario: Protecting LIN/CAN transceiver inputs against load-dump and ISO 7637-2 pulses in vehicle door modules. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed directly at connector entry point to shunt transients before reaching PHY layer. Use Value: 17.0 V clamping ensures transceiver supply rails remain below absolute maximum ratings during 100 V/500 ms load dump events. | Use Scenario: Safeguarding differential CANH/CANL lines in factory automation PLCs exposed to relay coil switching noise. IC Role / Device Role / Timing Role: Symmetric TVS pair (one per line) suppressing common-mode surges while preserving signal integrity up to 1 Mbps. Use Value: Sub-100 ns response time and 1500 W PPPM prevent bit errors and bus lock-up during 4 kV EFT bursts. |
| Consumer Power Adapter Input | Telecom DSL Line Interface |
Use Scenario: Secondary-side surge protection on 12 V DC output rails of wall-mounted AC/DC adapters. IC Role / Device Role / Timing Role: Standoff-clamp element placed after DC-DC converter to absorb residual transients from upstream rectifier stage. Use Value: 10 V VWM aligns with 12 V nominal rail; 5.0 µA ID minimizes quiescent loss in energy-efficient designs. | Use Scenario: Overvoltage protection on POTS line interface circuits in DSLAM line cards subjected to lightning-induced surges. IC Role / Device Role / Timing Role: Primary protection device bridging tip/ring lines to ground, handling longitudinal mode surges per ITU-T K.20. Use Value: Bidirectional symmetry eliminates need for polarity-aware routing on balanced telecom pairs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A-E3/57T | Uni-directional; 10 V VWM, 17.0 V VC, but requires cathode orientation and lacks AEC-Q101 qualification | Suitable only where polarity is fixed and automotive qualification is not required | Select when cost is prioritized over automotive compliance and board space allows orientation-aware placement |
| 1.5KE10CA | Through-hole DO-201 package; same 10 V VWM and bi-directionality, but higher RθJA (100 °C/W) and no MSL Level 1 rating | Used in legacy industrial power supplies where reflow compatibility is not needed | Choose for through-hole prototyping or repair scenarios where SMT process integration is unavailable |
Compared with SMAJ10A-E3/57T and 1.5KE10CA, SMCG10HE3/9AT uniquely combines AEC-Q101 qualification, MSL Level 1 reflow readiness, and bi-directional symmetry in a compact DO-215AB footprint - making it the optimal choice for new automotive and high-volume industrial SMT designs demanding zero-layout polarity constraints and guaranteed reliability.

FAQ
What is the clamping voltage of SMCG10HE3/9AT at its rated peak pulse current?
The SMCG10HE3/9AT has a maximum clamping voltage (VC) of 17.0 V at its specified peak pulse current (IPPM) of 88.2 A, measured under the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during transient events. The SMCG10HE3/9AT maintains this clamping performance due to its low incremental surge resistance and glass-passivated junction structure.
Is SMCG10HE3/9AT suitable for automotive applications?
Yes, SMCG10HE3/9AT is explicitly AEC-Q101 qualified, as confirmed by the HE3 suffix and documentation revision 14-Mar-12 (Document Number: 88457). It meets automotive reliability requirements including temperature cycling, humidity testing, and mechanical shock. The SMCG10HE3/9AT is widely deployed in engine control units, body electronics, and ADAS sensor interfaces where transient immunity and long-term stability are critical.
Does SMCG10HE3/9AT have polarity markings?
No, SMCG10HE3/9AT is a bi-directional TVS and carries no cathode band or polarity marking. Its symmetrical construction allows either terminal to serve as anode or cathode depending on transient polarity - simplifying PCB layout and eliminating orientation errors during automated placement. This feature is intrinsic to all CA-suffixed SMCG devices, including the SMCG10HE3/9AT.
What is the thermal resistance of SMCG10HE3/9AT?
The SMCG10HE3/9AT 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 pad per terminal. Its junction-to-lead resistance (RθJL) is 15 °C/W, supporting efficient heat transfer to the PCB. These values enable the SMCG10HE3/9AT to sustain 6.5 W power dissipation at TA = 50 °C without exceeding its 150 °C maximum junction temperature.
What does the "9AT" in SMCG10HE3/9AT indicate?
The "9AT" in SMCG10HE3/9AT is the preferred package code denoting 13-inch diameter plastic tape-and-reel packaging containing 3500 units. This format is optimized for high-speed SMT pick-and-place systems. The base part SMCG10HE3 is identical electrically and mechanically; only the packaging differs from variants like SMCG10HE3/57T (7-inch reel, 850 units). The SMCG10HE3/9AT ensures consistent feeding and reduced changeover downtime in volume production.
