Product details
Overview
SMCJ6.0AHE3/57T from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping ESD and surge transients on power and signal lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 1500 W peak pulse power (10/1000 µs), and clamps to ≤10.3 V at 145.6 A peak surge current - used for protecting automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the SMCJ6.0AHE3/57T datasheet, SMCJ6.0AHE3/57T pinout, SMCJ6.0AHE3/57T application, or SMCJ6.0AHE3/57T equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 1500 W surge rating, low clamping voltage (VC ≤10.3 V), and compatibility with automated SMT assembly on 8 mm × 8 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamping protection device across DC power rails or unidirectional signal paths. Its glass-passivated junction enables fast response (<1 ns), low incremental surge resistance, and stable breakdown behavior under repetitive transients.
Designed for compliance with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and ISO 7637-2 (automotive surge), it delivers robust protection without requiring external biasing or control logic - functioning purely as a passive crowbar element triggered by overvoltage events exceeding VBR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - maximum continuous reverse operating voltage before leakage exceeds 1000 µA; defines safe DC operating margin. |
| VBR min/max | 6.67 V / 7.37 V at IT = 10 mA - guaranteed breakdown range ensures consistent turn-on across temperature and unit variation. |
| VC @ IPPM | ≤10.3 V at 145.6 A - clamping voltage limits downstream IC stress during 10/1000 µs surges; critical for 5 V rail protection. |
| PPPM | 1500 W - peak pulse power handling per 10/1000 µs waveform; supports high-energy transients like load dump or inductive kick. |
| TJ max | +150 °C - maximum junction temperature; enables operation in under-hood automotive environments and industrial enclosures. |
| Package | SMC (DO-214AB) - standardized surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height; compatible with J-STD-020 MSL level 1 reflow. |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
Pinout & Package
SMCJ6.0AHE3/57T uses the standard SMC (DO-214AB) package: two-terminal, unidirectional configuration with cathode indicated by a band on the body. Leads are matte tin-plated and solderable per J-STD-002 and JESD 22-B102. Mounting requires 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or lower-potential node; completes conduction path during reverse-biased transient clamping. |
| Cathode | High-side connection point | Marked with band; connects to protected line (e.g., 5 V supply or CAN_H); conducts when voltage exceeds VBR. |
Key Features

FAQ
What is the clamping voltage of SMCJ6.0AHE3/57T at its rated peak pulse current?
The SMCJ6.0AHE3/57T clamps to a maximum of 10.3 V at its rated peak pulse current of 145.6 A (10/1000 µs waveform). This value is measured under standardized test conditions with 0.31" × 0.31" copper pads per terminal and represents the upper limit of voltage imposed on protected circuitry during surge events. The SMCJ6.0AHE3/57T achieves this low VC while maintaining 1500 W power handling, making it suitable for safeguarding 5 V logic systems.
Is SMCJ6.0AHE3/57T qualified for automotive applications?
Yes, SMCJ6.0AHE3/57T is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HE3". This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD per JESD22-A114. The SMCJ6.0AHE3/57T is approved for use in automotive subsystems such as body control modules, ADAS sensor interfaces, and infotainment power rails where reliability under harsh environmental conditions is required.
What is the standoff voltage and breakdown range of SMCJ6.0AHE3/57T?
The SMCJ6.0AHE3/57T has a standoff voltage (VWM) of 6.0 V and a breakdown voltage (VBR) range of 6.67 V to 7.37 V at 10 mA test current. This ensures reliable blocking of normal operating voltages while guaranteeing activation within a tightly controlled window during overvoltage events. The SMCJ6.0AHE3/57T maintains this specification across its full operating temperature range of −55 °C to +150 °C, supporting deployment in under-hood and industrial environments.
Does SMCJ6.0AHE3/57T require special PCB layout considerations?
Yes, SMCJ6.0AHE3/57T requires minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal to achieve its rated 1500 W peak pulse power and thermal performance. Smaller pads reduce heat dissipation and cause premature failure under surge conditions. The SMCJ6.0AHE3/57T also demands short, low-inductance traces to the protected node and ground plane to preserve sub-nanosecond response time and avoid voltage overshoot during fast transients.
How does SMCJ6.0AHE3/57T differ from bidirectional variants like SMCJ6.0CA?
The SMCJ6.0AHE3/57T is unidirectional and includes a cathode band marking, whereas SMCJ6.0CA is bidirectional with no polarity marking and symmetric clamping in both directions. The SMCJ6.0AHE3/57T is intended for DC-biased lines (e.g., 5 V supply rails), while SMCJ6.0CA suits AC-coupled or floating signal paths (e.g., RS-485, CAN). Their VBR and VC values differ slightly due to internal structure - the SMCJ6.0AHE3/57T has VBR = 6.67–7.37 V, while SMCJ6.0CA has VBR = 6.40–7.25 V.
