Product details
Overview
SMCJ160CA-E3/9AT 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 1500 W peak pulse power rating, 160 V stand-off voltage (VWM), and 259 V maximum clamping voltage (VC) at 5.8 A peak pulse current. It protects sensitive ICs, MOSFETs, and sensor signal lines in automotive and industrial power electronics against inductive switching transients and lightning-induced surges.
For engineers reviewing the SMCJ160CA-E3/9AT datasheet, SMCJ160CA-E3/9AT pinout, SMCJ160CA-E3/9AT application, or SMCJ160CA-E3/9AT equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, RoHS-compliant commercial-grade construction, thermal resistance data, and direct alternatives for ESD/surge protection design-in.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with breakdown voltage (VBR) of 178–197 V at 1 mA test current and ±1.0 μA max reverse leakage at 160 V stand-off. Its low incremental surge resistance enables fast clamping response to 10/1000 μs transients without degradation under repeated stress.
Thermal performance is defined by RθJA = 75 °C/W (junction-to-ambient, on recommended 8.0 mm × 8.0 mm copper pads) and RθJL = 15 °C/W (junction-to-lead), supporting reliable operation up to TJ = +150 °C. The device meets MSL Level 1 per J-STD-020 and is rated for 260 °C lead-free reflow peak temperature.

|---|---|
Use Scenario: Protection of 12 V/24 V power rails feeding ECUs, body control modules, and lighting drivers against load dump and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional clamping element placed upstream of DC-DC converters and LDOs to limit transient overvoltage. Use Value: Withstands 1500 W surges while clamping to ≤259 V, preventing damage to 36 V-rated input stages and ensuring ASIL-B system robustness. |
Use Scenario: Shielding analog and digital signal paths (e.g., CAN, LIN, RS-485, thermistor inputs) from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance (<50 pF typical) shunt protector placed at connector interface to divert fast transients before reaching MCU GPIO or ADC front-end. Use Value: Sub-μA leakage at 160 V ensures no signal distortion on high-impedance sensor nodes; symmetrical clamping eliminates need for polarity-aware layout. |
| Telecom Power Feeds | Consumer Appliance Motor Controls |
Use Scenario: Surge suppression on PoE-powered equipment (e.g., IP cameras, access points) where 48 V DC feeds are exposed to induced lightning surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on secondary-side DC bus, coordinated with upstream MOVs and gas discharge tubes. Use Value: 259 V clamping voltage provides safe margin below 300 V-rated DC-DC input capacitors and isolators, enabling compact, cost-effective Class 4 compliance. |
Use Scenario: Protecting microcontroller I/O and gate drivers in washing machine, HVAC, or power tool inverters subjected to motor commutation spikes. IC Role / Device Role / Timing Role: Fast-response shunt suppressor across H-bridge supply rails and feedback sensing nodes to prevent latch-up or false PWM triggering. Use Value: 10 ns response time and 75 °C/W thermal resistance allow repeated surge absorption without thermal runaway during high-duty-cycle motor starts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA-E3/52T | Same VWM (160 V) and VC (259 V), but lower PPPM (600 W); SMB package (DO-214AA) with smaller footprint and higher RθJA (110 °C/W). | Lower surge energy handling; suitable only for Class 2–3 IEC 61000-4-5 or board-level ESD, not full load-dump scenarios. | Select when space-constrained layouts preclude SMC and surge threat level is moderate. |
| SMCJ160A-E3/9AT | Unidirectional variant with identical VWM (160 V), VC (259 V), and PPPM (1500 W); includes cathode band marking and forward voltage (VF = 3.5 V @ 100 A). | Requires polarity-aware placement; unsuitable for AC-coupled or floating signal lines where bidirectional clamping is mandatory. | Choose only for DC rail protection with known polarity and where forward conduction must be blocked. |
Compared with SMCJ160CA-E3/9AT, SMBJ160CA-E3/52T trades surge capacity for compactness, while SMCJ160A-E3/9AT sacrifices bidirectionality for unidirectional blocking-making SMCJ160CA-E3/9AT the sole choice for polarity-agnostic, high-energy protection in shared-bus or differential-signal systems.

FAQ
What is the clamping voltage of the SMCJ160CA-E3/9AT under a 10/1000 µs surge?
The SMCJ160CA-E3/9AT clamps to a maximum of 259 V at its rated peak pulse current of 5.8 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet revision 09-Jan-2024. The clamping voltage directly defines the upper voltage limit imposed on protected circuitry during surge events, making it critical for selecting downstream voltage ratings. SMCJ160CA-E3/9AT maintains this performance across its full operating temperature range.
Is the SMCJ160CA-E3/9AT suitable for automotive applications?
The SMCJ160CA-E3/9AT is RoHS-compliant and built on the same die and package as AEC-Q101-qualified variants (e.g., SMCJ160CAHE3_A/I), but it carries the commercial-grade E3 suffix and is not itself AEC-Q101 certified. For non-safety-critical automotive subsystems like infotainment power rails or body electronics with relaxed qualification requirements, SMCJ160CA-E3/9AT is widely deployed. However, for ASIL-B/C systems, the HE3 or HM3 automotive-grade versions of SMCJ160CA-E3/9AT must be specified.
How does the bidirectional nature of the SMCJ160CA-E3/9AT affect PCB layout?
The SMCJ160CA-E3/9AT has no polarity marking and functions identically in both directions, eliminating orientation constraints during automated placement. This simplifies layout for AC-coupled lines, differential buses (e.g., RS-485), or floating sensor outputs where voltage polarity reversal is possible. Unlike unidirectional TVS diodes such as SMCJ160A-E3/9AT, the SMCJ160CA-E3/9AT requires no cathode alignment check, reducing assembly errors and enabling symmetric routing on dense boards.
What is the thermal resistance of the SMCJ160CA-E3/9AT, and how does it impact derating?
The SMCJ160CA-E3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal, and RθJL = 15 °C/W. This means power dissipation must be derated above 25 °C ambient-per Figure 2 in the Vishay datasheet-to avoid exceeding the +150 °C maximum junction temperature. At 70 °C ambient, the usable power drops to ~4.5 W; sustained surge duty cycles require attention to pad area and airflow to maintain thermal safety margins for SMCJ160CA-E3/9AT.
Does the SMCJ160CA-E3/9AT meet any industry surge immunity standards?
Yes-the SMCJ160CA-E3/9AT's 1500 W peak pulse power rating (10/1000 µs) enables compliance with IEC 61000-4-5 Ed. 3 Level 4 (4 kV line-to-line, 2 kV line-to-ground) when used with appropriate system-level filtering and layout. Its low clamping voltage (259 V) and fast response ensure protected circuits remain within safe operating areas during standardized surge testing. While the device itself is not "certified" to IEC standards, its parameters are routinely leveraged in certified end-equipment designs for industrial and automotive applications using SMCJ160CA-E3/9AT.
