Product details
Overview
SMCJ6.0CAHE3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 6.0 V standoff voltage, 1500 W peak pulse power rating, and 10.3 V clamping voltage at 145.6 A peak pulse current. It protects sensitive ICs, MOSFETs, and sensor signal lines against inductive switching transients and lightning-induced surges in automotive and industrial systems.
For engineers reviewing the SMCJ6.0CAHE3_A/I datasheet, SMCJ6.0CAHE3_A/I pinout, SMCJ6.0CAHE3_A/I application, or SMCJ6.0CAHE3_A/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 1500 W surge handling under 10/1000 µs waveform, low incremental surge resistance, and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This device operates as a voltage-clamped shunt protector: during transient overvoltage events exceeding its breakdown threshold (6.67–7.37 V), it rapidly switches to low-impedance conduction, diverting surge current away from downstream circuitry while limiting voltage across protected nodes to ≤10.3 V. Its glass-passivated junction ensures stable avalanche characteristics and long-term reliability under repetitive stress.
Designed for bidirectional operation, SMCJ6.0CAHE3_A/I exhibits symmetrical electrical behavior in both polarities-no polarity marking required-and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow peak temperature tolerance. Thermal resistance is 75 °C/W junction-to-ambient (typical) on recommended 8.0 mm × 8.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 6.0 V - Maximum continuous reverse operating voltage before significant leakage; defines safe operating margin below clamping threshold. |
| Breakdown Voltage (VBR) | 6.67–7.37 V at 10 mA - Confirmed avalanche initiation range; ensures reliable turn-on during fast transients. |
| Clamping Voltage (VC) | 10.3 V at 145.6 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge; critical for IC-level voltage margining. |
| Peak Pulse Power (PPPM) | 1500 W - Energy-handling capacity under standardized 10/1000 µs waveform; enables robust protection against IEC 61000-4-5 Level 4 surges. |
| Junction Temperature Range | −55 °C to +150 °C - Specifies full operational envelope for automotive under-hood and industrial environments. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 7.75 mm × 6.22 mm footprint; supports automated pick-and-place and reflow soldering. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per AEC specification. |
Pinout & Package
SMCJ6.0CAHE3_A/I uses the SMC (DO-214AB) package: a surface-mount, bidirectional device with no polarity marking. The two terminals are electrically symmetric; neither is designated anode or cathode. Mounting requires 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal for rated thermal and surge performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Surge Input / Protected Node Connection | Connects to line or signal path requiring transient suppression; bidirectional symmetry allows flexible routing without orientation constraints. |
| Terminal 2 | Surge Return / Reference Node Connection | Typically tied to system ground or common reference plane; completes low-inductance current path for diverted surge energy. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns-no band marking required. |
| 1500 W Peak Pulse Power | Supports IEC 61000-4-5 surge immunity up to 4 kV (line-earth) and 2 kV (line-line) in properly designed interfaces. |
| AEC-Q101 Qualification | Validates suitability for automotive powertrain, body electronics, and ADAS modules where field reliability is non-negotiable. |
| Low Incremental Surge Resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns rise time), improving protection effectiveness for high-speed logic. |
| MSL Level 1 Rating | Permits unlimited floor life and standard lead-free reflow without baking-reduces manufacturing overhead and moisture sensitivity risk. |
Applications

FAQ
What is the clamping voltage of SMCJ6.0CAHE3_A/I at its rated peak pulse current?
The clamping voltage of SMCJ6.0CAHE3_A/I is 10.3 V measured at 145.6 A peak pulse current under the standardized 10/1000 µs waveform. This value represents the maximum voltage imposed on the protected circuit during worst-case surge conditions and is confirmed in Vishay's official datasheet revision 09-Jan-2024 (Document Number: 88394). SMCJ6.0CAHE3_A/I maintains this clamping performance across its full operating temperature range.
Is SMCJ6.0CAHE3_A/I suitable for automotive applications?
Yes, SMCJ6.0CAHE3_A/I is AEC-Q101 qualified, making it suitable for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its construction includes glass-passivated junctions, MSL Level 1 moisture sensitivity rating, and validated performance from −55 °C to +150 °C. SMCJ6.0CAHE3_A/I meets automotive surge immunity requirements when mounted per recommended pad layout and used within its specified electrical limits.
How does the bidirectional configuration of SMCJ6.0CAHE3_A/I affect PCB layout?
The bidirectional configuration of SMCJ6.0CAHE3_A/I eliminates polarity constraints during placement-no cathode band marking is present, and either terminal may connect to line or return. This simplifies PCB routing for AC-coupled or floating signals and avoids orientation errors in automated assembly. SMCJ6.0CAHE3_A/I requires symmetric 8.0 mm × 8.0 mm copper pads on both terminals to achieve rated thermal dissipation and surge current handling per Vishay's datasheet guidelines.
What is the standoff voltage (VWM) of SMCJ6.0CAHE3_A/I, and why is it important?
The standoff voltage (VWM) of SMCJ6.0CAHE3_A/I is 6.0 V-the maximum DC or continuous peak reverse voltage the device can withstand without entering avalanche conduction. This parameter ensures normal circuit operation without leakage or power loss, while maintaining sufficient margin below the 6.67–7.37 V breakdown range. Selecting SMCJ6.0CAHE3_A/I with a VWM closely matched to system operating voltage maximizes protection headroom without compromising signal integrity.
Does SMCJ6.0CAHE3_A/I require external heat sinking for standard operation?
No, SMCJ6.0CAHE3_A/I does not require external heat sinking under typical transient conditions because its 1500 W peak pulse power is rated for short-duration events (≤1000 µs), not continuous dissipation. Its 6.5 W steady-state power dissipation (PD) is managed via PCB copper thermal mass. When mounted on the recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, SMCJ6.0CAHE3_A/I achieves a typical junction-to-ambient thermal resistance of 75 °C/W, sufficient for intermittent surge duty cycles in automotive and industrial applications.
