Product details
Overview
SMCJ160HE3/9AT from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection of sensitive electronics. It features a 160 V stand-off voltage (VWM), 178–197 V breakdown voltage (VBR), 259 V clamping voltage (VC) at 5.8 A peak pulse current, and 1500 W peak pulse power dissipation (10/1000 µs waveform), suitable for automotive power line and industrial DC bus surge protection.
For engineers reviewing the SMCJ160HE3/9AT datasheet, SMCJ160HE3/9AT pinout, SMCJ160HE3/9AT application, or SMCJ160HE3/9AT equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, RoHS-compliant matte tin leads, and MSL Level 1 moisture sensitivity rating.
Technical Context
The SMCJ160HE3/9AT operates as a silicon avalanche diode with glass-passivated junction, delivering fast response time (<1 ns) to transient events such as ESD, lightning-induced surges, and inductive switching spikes. Its low incremental surge resistance ensures stable clamping under high-current transients, while its thermal resistance (RθJA = 75 °C/W) supports reliable operation on standard 8.0 mm × 8.0 mm copper pads.
Designed for unidirectional protection only, it exhibits forward voltage drop of 3.5 V at 100 A (IF), reverse leakage ≤1.0 µA at VWM, and meets UL 497B recognition (QVGQ2) for protector classification. The device is rated for -55 °C to +150 °C operating junction temperature and complies with JESD201 Class 2 whisker testing due to its HE3 suffix.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160AHE3/A | Lower PPPM (400 W), smaller DO-214AC (SMA) package, same VWM/VBR range | Not suitable for 1500 W surge events; limited to low-energy transients | Select only when board space is constrained and surge energy is ≤400 W |
| 1.5KE160A | Through-hole TO-218 package, same 160 V VWM, but higher VC (259 V → 260 V) and identical PPPM (1500 W) | Requires PCB through-hole mounting; incompatible with automated SMT assembly | Choose only for legacy through-hole designs or where thermal mass of TO-218 is preferred |
Compared with SMAJ160AHE3/A and 1.5KE160A, the SMCJ160HE3/9AT delivers identical 1500 W surge capability in an AEC-Q101-qualified, surface-mount DO-214AB package-enabling automotive-grade reliability without sacrificing SMT manufacturability or thermal performance.

FAQ
What is the maximum clamping voltage of the SMCJ160HE3/9AT under standard test conditions?
The SMCJ160HE3/9AT has a maximum clamping voltage (VC) of 259 V when subjected to its rated peak pulse current (IPPM) of 5.8 A using the 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting during surge events. The clamping performance is guaranteed across the full operating temperature range (-55 °C to +150 °C).
Is the SMCJ160HE3/9AT suitable for automotive applications?
Yes, the SMCJ160HE3/9AT is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its construction includes glass-passivated junction, JESD201 Class 2 whisker-resistant plating, and UL 497B recognition-making it appropriate for engine control units, body control modules, and ADAS sensor interfaces where reliability under thermal cycling and vibration is critical. The SMCJ160HE3/9AT meets all required stress tests per AEC-Q101 Rev D.
What does the "HE3" suffix indicate in SMCJ160HE3/9AT?
The "HE3" suffix in SMCJ160HE3/9AT denotes two key attributes: "H" signifies AEC-Q101 qualification, and "E3" indicates RoHS-compliant, commercial-grade construction with matte tin leads. Unlike base "E3" parts, the "HE3" variant undergoes additional automotive-grade reliability screening-including high-temperature reverse bias (HTRB), temperature cycling, and accelerated moisture resistance-ensuring suitability for mission-critical automotive systems.
How does the SMCJ160HE3/9AT differ from bi-directional SMCJ160CA variants?
The SMCJ160HE3/9AT is unidirectional, meaning it conducts only in reverse bias above VBR and blocks forward current beyond VF ≈ 3.5 V at 100 A. In contrast, SMCJ160CA is bi-directional with symmetrical clamping in both polarities and no cathode marking. The SMCJ160HE3/9AT is intended for DC line protection where polarity is fixed; using it in AC or floating applications would result in unintended forward conduction and failure.
What is the recommended PCB pad layout for optimal thermal performance of the SMCJ160HE3/9AT?
Vishay specifies a minimum pad layout of 0.31" × 0.31" (8.0 mm × 8.0 mm) copper area per terminal for the SMCJ160HE3/9AT to achieve rated power dissipation and thermal resistance (RθJA = 75 °C/W). Use solid internal copper planes connected via multiple thermal vias to enhance heat spreading. Avoid narrow traces or isolated pads, as insufficient copper reduces surge current handling and accelerates junction temperature rise during repetitive transients.
