Product details
Overview
SMCG60CAHE3/9AT from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for robust overvoltage protection on signal and power lines. It features a 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (10/1000 µs), clamping voltage of 96 V at 15.5 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMCG60CAHE3/9AT datasheet, SMCG60CAHE3/9AT pinout, SMCG60CAHE3/9AT application, or SMCG60CAHE3/9AT equivalent, this device serves as a high-energy, low-clamping bidirectional TVS for CAN bus, sensor interfaces, and automotive control modules where fast response (<1 ns), low incremental surge resistance, and MSL Level 1 reflow compatibility are critical.
Technical Context
The SMCG60CAHE3/9AT operates as a symmetrical avalanche diode with identical electrical characteristics in both directions, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable VBR tolerance and long-term reliability under repetitive surge stress.
Designed for surface-mount automated assembly, it uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets UL 94 V-0 flammability requirements. Thermal resistance is 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-lead), supporting sustained operation up to TJ = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 66.7 V / 73.7 V at 1 mA - Ensures predictable, tight-breakdown activation across production lots |
| VC @ IPPM | 96 V at 15.5 A - Low clamping voltage limits downstream IC stress during 10/1000 µs transients |
| PPPM | 1500 W - Withstands high-energy surges such as ISO 7637-2 Pulse 5a (load dump) |
| ID @ VWM | 1.0 µA - Ultra-low leakage preserves signal integrity in high-impedance sensor circuits |
| TJ max | +150 °C - Enables deployment in under-hood automotive environments |

Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces |
| Glass-passivated junction | Ensures stable VBR over temperature and lifetime, with reduced parameter drift vs. epoxy-passivated alternatives |

| MSL Level 1 rating | Eliminates pre-bake requirement and supports direct placement into high-volume SMT lines |
Applications
| Automotive CAN Bus Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting CAN_H/CAN_L lines in vehicle ECUs against load dump, jump-start, and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point to shunt surge energy before reaching CAN transceiver. Use Value: Clamps to 96 V while sustaining 1500 W peak power, preventing transceiver latch-up or permanent damage under harsh automotive transients. | Use Scenario: Safeguarding analog outputs (e.g., 4–20 mA, 0–10 V) of pressure/temperature sensors in factory automation systems. IC Role / Device Role / Timing Role: Parallel-connected TVS at sensor PCB edge to absorb field-induced surges from nearby motor drives or relay switching. Use Value: 1.0 µA leakage at 60 V avoids loading high-impedance output stages; symmetrical behavior eliminates need for polarity-aware layout. |
| USB 2.0 Data Line Protection | Automotive Camera Power Line Protection |
Use Scenario: Guarding D+/D− lines in USB host/device ports against ESD (IEC 61000-4-2 ±15 kV contact) and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance TVS placed adjacent to USB connector to clamp sub-nanosecond ESD events without signal distortion. Use Value: Junction capacitance <100 pF (typ.) at 0 V bias preserves signal integrity up to 480 Mbps; bidirectional symmetry matches differential signaling. | Use Scenario: Protecting 12 V power input to rear-view or surround-view cameras mounted in vehicle exteriors. IC Role / Device Role / Timing Role: Primary front-end TVS on camera module's power rail to absorb load dump (up to 60 V surge) and ISO 16750-2 transients. Use Value: 1500 W PPPM rating handles 10/1000 µs load dump surges; AEC-Q101 qualification ensures reliability across -40 °C to +125 °C ambient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60A-E3/57T | Unidirectional; same VWM/VBR/PPPM but lacks bidirectional symmetry and AEC-Q101 qualification | Requires polarity-aware layout; not approved for automotive under-hood use | Select only for cost-sensitive industrial DC rails where polarity is fixed and automotive qualification is unnecessary |
| SMCJ60CA | Same bidirectional functionality and AEC-Q101 rating, but in larger DO-214AB (SMC) package with higher thermal mass | Higher RθJA (50 °C/W vs. 75 °C/W) but lower clamping voltage (94 V) and higher IPPM (16.0 A) | Prefer when board space allows and higher surge margin or lower clamping is prioritized over compactness |
Compared with SMAJ60A-E3/57T and SMCJ60CA, the SMCG60CAHE3/9AT uniquely balances AEC-Q101 compliance, DO-215AB compactness, and precise 96 V clamping-making it optimal for space-constrained automotive modules requiring validated reliability without layout polarity constraints.

FAQ
What is the clamping voltage of SMCG60CAHE3/9AT at its rated peak pulse current?
The SMCG60CAHE3/9AT has a maximum clamping voltage (VC) of 96 V at 15.5 A peak pulse current (IPPM), measured under the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is confirmed in the Vishay datasheet revision 09-Jan-2024, page 2, Electrical Characteristics table.
Is SMCG60CAHE3/9AT suitable for automotive applications?
Yes, SMCG60CAHE3/9AT is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood and body electronics. Its construction-glass-passivated junction, MSL Level 1 reflow compatibility, and operation from -55 °C to +150 °C-meets key automotive reliability requirements. The "HE3" suffix denotes AEC-Q101 qualification per Vishay's ordering nomenclature.
Does SMCG60CAHE3/9AT have polarity markings on the package?
No, SMCG60CAHE3/9AT is a bidirectional TVS diode and carries no polarity marking-the "CA" suffix indicates symmetrical breakdown in both directions. Unlike unidirectional variants (e.g., SMCG60A), it has no cathode band; both terminals are functionally identical for surge conduction.
What is the thermal resistance of SMCG60CAHE3/9AT, and how does it affect PCB layout?
The SMCG60CAHE3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. To maintain safe junction temperatures under sustained power dissipation, designers must provide adequate copper area and avoid excessive trace length between the device and thermal planes.
How does the SMCG60CAHE3/9AT differ from the SMCG60A variant?
The SMCG60CAHE3/9AT is bidirectional with symmetrical VBR and clamping in both directions, while SMCG60A is unidirectional and features a cathode band marking. Both share the same VWM (60 V), PPPM (1500 W), and AEC-Q101 qualification (HE3 suffix), but only SMCG60CAHE3/9AT supports AC or differential line protection without polarity constraints.
