Product details
Overview
SMCJ160-E3/9AT from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 160 V standoff voltage (VWM), 178–197 V breakdown range (VBR), 259 V clamping voltage (VC) at 5.8 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 µs waveform.
For engineers reviewing the SMCJ160-E3/9AT datasheet, SMCJ160-E3/9AT pinout, SMCJ160-E3/9AT application, or SMCJ160-E3/9AT equivalent, key selection criteria include clamping performance under automotive load-dump transients, thermal derating above 25 °C, RoHS-compliant matte tin terminations, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The SMCJ160-E3/9AT operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its specified breakdown range. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1.0 µA at VWM), while the low incremental surge resistance enables effective clamping during fast transients such as ISO 7637-2 Pulse 5a.
Thermally, it exhibits RθJA = 75 °C/W and RθJL = 15 °C/W, supporting operation from –55 °C to +150 °C junction temperature. The device is rated for 200 A non-repetitive forward surge (IFSM, 8.3 ms half-sine) and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - Maximum continuous reverse operating voltage before clamping begins |

| VC @ IPPM | 259 V - Clamped voltage across device at 5.8 A peak pulse current; determines protected circuit stress level |
| PPPM | 1500 W - Peak transient power handling capability with 10/1000 µs waveform; critical for load-dump immunity |
| ID @ VWM | <1.0 µA - Reverse leakage at rated standoff voltage; ensures minimal standby power loss and signal integrity |
| TJ max. | +150 °C - Maximum junction temperature; sets thermal design margin for PCB copper pad layout and ambient conditions |
| IFSM | 200 A - Non-repetitive surge current rating (8.3 ms half-sine); validates robustness against inrush or fault currents |
Pinout & Package
Package: DO-214AB (SMCJ), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Polarity indicated by cathode band on body end.

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs from ISO 7637-2 load-dump transients up to 120 V for 400 ms. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground to clamp surges before they reach downstream regulators and microcontrollers. Use Value: SMCJ160-E3/9AT's 259 V clamping voltage ensures protected ICs see no more than 259 V during worst-case transients, well below typical 36 V absolute maximum ratings of automotive LDOs. | Use Scenario: Safeguarding analog sensor outputs (e.g., pressure or temperature sensors) connected to PLC I/O modules exposed to field wiring transients. IC Role / Device Role / Timing Role: Bidirectional protection is not required here; unidirectional SMCJ160-E3/9AT guards against negative-going transients on grounded-signal lines. Use Value: With <1.0 µA leakage at 160 V, SMCJ160-E3/9AT introduces negligible error in high-impedance sensor signal paths while delivering 1500 W transient absorption. |
| Telecom DC Power Input Protection | Motor Drive Control Signal Protection |
Use Scenario: Securing -48 V telecom rectifier outputs against lightning-induced surges and switching noise on backplane distribution lines. IC Role / Device Role / Timing Role: Mounted at board edge with short traces to ground plane; clamps reverse polarity faults and differential-mode surges. Use Value: SMCJ160-E3/9AT's 178–197 V VBR range aligns with -48 V system derating margins, enabling reliable turn-on before upstream fuses open during sustained overvoltage events. | Use Scenario: Shielding isolated gate driver inputs (e.g., optocoupler or SiO2-isolated inputs) from coupling noise generated by IGBT/MOSFET switching in motor inverters. IC Role / Device Role / Timing Role: Placed adjacent to driver IC input pins to limit transient voltage swing to safe logic thresholds. Use Value: Fast response time and low clamping voltage (259 V) prevent false triggering or latch-up in sensitive CMOS input stages during high-dV/dt noise events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-E3/61T | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher RθJA (110 °C/W) | Suitable for space-constrained, lower-energy transients; not recommended for automotive load-dump | Select when board area is limited and peak surge energy is ≤400 W |
| SMCJ160AHE3/9AT | Identical electrical specs but AEC-Q101 qualified (HE3 suffix); same DO-214AB package and thermal performance | Required for automotive OEM designs needing formal qualification evidence; otherwise functionally interchangeable | Choose SMCJ160AHE3/9AT if AEC-Q101 documentation and traceability are mandatory |
Compared with SMAJ160A-E3/61T and SMCJ160AHE3/9AT, the SMCJ160-E3/9AT offers optimal balance of 1500 W surge capacity, industry-standard DO-214AB footprint, and commercial-grade cost structure-making it ideal for industrial and telecom applications where AEC-Q101 is unnecessary but high-energy clamping is essential.

FAQ
What is the clamping voltage of the SMCJ160-E3/9AT and how is it measured?
The SMCJ160-E3/9AT has a maximum clamping voltage (VC) of 259 V, measured at a peak pulse current (IPPM) of 5.8 A using a standardized 10/1000 µs double-exponential waveform. This value represents the upper limit of voltage seen across the device during a transient event and is critical for ensuring downstream components remain within their absolute maximum voltage ratings. The SMCJ160-E3/9AT achieves this clamping performance consistently due to its low incremental surge resistance and glass-passivated junction.
Is the SMCJ160-E3/9AT suitable for automotive applications?
The SMCJ160-E3/9AT is RoHS-compliant and manufactured in an AEC-Q101-qualified process flow (as confirmed by Vishay's documentation), but the E3 suffix denotes commercial-grade qualification-not the HE3 automotive-grade variant. While it shares identical electrical and thermal specs with SMCJ160AHE3/9AT, the SMCJ160-E3/9AT lacks formal AEC-Q101 certification documentation. For production automotive use, specify SMCJ160AHE3/9AT; the SMCJ160-E3/9AT remains appropriate for industrial or telecom systems requiring similar surge performance.
What does the "9AT" suffix mean in SMCJ160-E3/9AT?
The "9AT" suffix in SMCJ160-E3/9AT indicates the packaging configuration: 13-inch diameter plastic tape and reel, with a base quantity of 3500 devices per reel. This format supports high-volume automated SMT placement and is compatible with standard pick-and-place equipment. The "E3" portion confirms RoHS compliance and commercial-grade qualification, while the absence of "H" distinguishes it from the AEC-Q101-qualified HE3 variant.
How does the thermal performance of the SMCJ160-E3/9AT affect PCB layout?
The SMCJ160-E3/9AT has a junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on minimum recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. To maintain TJ ≤ 150 °C under full 1500 W surge conditions, designers must ensure adequate copper area, avoid thermal bottlenecks, and consider derating above TA = 25 °C per Figure 2 in the datasheet. Poor layout can elevate junction temperature beyond specification, reducing surge endurance and long-term reliability of the SMCJ160-E3/9AT.
Can the SMCJ160-E3/9AT be used in bidirectional protection circuits?
No-the SMCJ160-E3/9AT is a unidirectional TVS diode, identifiable by its cathode band marking and specified electrical characteristics (e.g., VBR, VC, ID) for reverse-biased operation only. For bidirectional protection, Vishay specifies part numbers ending in "CA", such as SMCJ160CA. Using the SMCJ160-E3/9AT in a bidirectional configuration would result in forward conduction during positive transients, potentially damaging the device or failing to protect the circuit. Always verify polarity and device type before integration; the SMCJ160-E3/9AT functions exclusively as a unidirectional clamp.
