Product details
Overview
SMCJ160CAHE3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients up to 259 V at 5.8 A peak pulse current, with 1500 W peak pulse power rating and 160 V standoff voltage. It protects sensitive signal lines and power rails in automotive ECUs, industrial I/O modules, and telecom interface circuits against ESD, lightning surges, and inductive switching spikes.
For engineers reviewing the SMCJ160CAHE3/57T datasheet, SMCJ160CAHE3/57T pinout, SMCJ160CAHE3/57T application, or SMCJ160CAHE3/57T equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 1500 W surge handling, low thermal resistance (RθJL = 15 °C/W), and compatibility with automated SMT assembly on standard PCB pad layouts.
Technical Context
The SMCJ160CAHE3/57T uses a glass-passivated silicon junction optimized for fast response (<1 ps) to transient overvoltages, with symmetrical breakdown behavior in both directions due to its bidirectional construction. Its clamping voltage of 259 V at 5.8 A (10/1000 µs waveform) ensures robust protection while maintaining safe margin above the 160 V working voltage.
Thermally, it features RθJA = 75 °C/W (on recommended 8.0 mm × 8.0 mm copper pads) and RθJL = 15 °C/W, enabling reliable operation up to TJ = +150 °C. The device meets J-STD-020 MSL Level 1 and is qualified to AEC-Q101 for automotive under-hood applications.

FAQ
What is the clamping voltage of the SMCJ160CAHE3/57T at its rated peak pulse current?
The SMCJ160CAHE3/57T has a maximum clamping voltage (VC) of 259 V when subjected to a 10/1000 µs waveform at 5.8 A peak pulse current. This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during surge events, ensuring downstream components remain within safe operating limits.
Is the SMCJ160CAHE3/57T suitable for automotive applications?
Yes, the SMCJ160CAHE3/57T carries AEC-Q101 qualification and is explicitly rated for automotive use. Its construction-including glass-passivated junction, MSL Level 1 rating, and operation up to +150 °C junction temperature-meets stringent reliability requirements for engine control units, body electronics, and ADAS subsystems.
How does the bidirectional design of the SMCJ160CAHE3/57T affect its circuit implementation?
The bidirectional nature of the SMCJ160CAHE3/57T eliminates polarity marking and enables direct placement across AC-coupled, differential, or floating signal paths-such as CAN bus lines or Ethernet PHY transformers-without risk of reverse connection. This simplifies layout, reduces BOM count, and improves design robustness in noise-prone environments.
What is the thermal resistance from junction to lead (RθJL) for the SMCJ160CAHE3/57T?
The SMCJ160CAHE3/57T has a typical junction-to-lead thermal resistance (RθJL) of 15 °C/W. This low value supports efficient heat transfer from the silicon die to the PCB copper via the leads, enabling sustained power dissipation and improved reliability during repetitive surge events or elevated ambient temperatures.
Does the SMCJ160CAHE3/57T require special PCB layout considerations?
Yes-the SMCJ160CAHE3/57T should be mounted on minimum 8.0 mm × 8.0 mm copper pads per terminal to achieve rated 1500 W pulse power performance. Smaller pads reduce thermal mass and increase junction temperature, derating both peak pulse current and clamping voltage. Trace inductance must also be minimized to preserve fast response.
