Product details
Overview
1.5SMC160AHE3/9AT from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 1500 W peak pulse power (10/1000 μs), 136 V standoff voltage (VWM), and 219 V clamping voltage (VC) at 6.8 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the 1.5SMC160AHE3/9AT datasheet, 1.5SMC160AHE3/9AT pinout, 1.5SMC160AHE3/9AT application, or 1.5SMC160AHE3/9AT equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device triggered by overvoltage transients, leveraging a glass-passivated silicon junction to achieve sub-nanosecond response time and stable breakdown behavior. Its unidirectional configuration provides forward conduction capability while suppressing reverse surges up to 219 V.
The device is rated for 1500 W peak pulse power under standardized 10/1000 μs waveform conditions, with thermal resistance of 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-leads), enabling reliable operation in ambient temperatures from –65 °C to +150 °C when mounted per recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe working margin below breakdown. |
| VBR (Breakdown Voltage) | 152–168 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 219 V at IPPM = 6.8 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 1500 W - Energy-handling capacity under standard lightning/surge waveform; supports IEC 61000-4-5 Level 4 compliance. |
| ID (Reverse Leakage) | 1.0 μA at VWM - Ultra-low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max | +150 °C - Enables use in under-hood automotive environments and thermally constrained industrial enclosures. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22 standards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A-E3/52T | Lower PPPM (600 W), SMB package (smaller footprint), same VWM (136 V), higher VC (230 V) | Less robust for high-energy surges; suitable only where space constraints outweigh power handling needs. | Select when board area is critical and surge threat level is ≤Level 3 per IEC 61000-4-5. |
| 1.5KE160A | Through-hole DO-201 package, identical electrical specs but incompatible with SMT assembly and automotive vibration requirements. | Not AEC-Q101 qualified; lacks MSL Level 1 rating; unsuitable for automated production or under-hood use. | Choose only for legacy through-hole designs or non-automotive prototyping where rework tolerance is prioritized. |
Compared with SMBJ160A-E3/52T and 1.5KE160A, the 1.5SMC160AHE3/9AT delivers superior surge robustness in an AEC-Q101-qualified SMT package, enabling direct integration into automotive and industrial production lines without layout or reliability compromises.

FAQ
What is the clamping voltage of the 1.5SMC160AHE3/9AT under maximum surge conditions?
The 1.5SMC160AHE3/9AT exhibits a maximum clamping voltage (VC) of 219 V when subjected to its rated peak pulse current of 6.8 A under the standardized 10/1000 μs waveform. This value is measured at TJ = 25 °C with devices mounted on 8.0 mm × 8.0 mm copper pads per Vishay's recommended layout, ensuring consistent protection performance across production units.
Is the 1.5SMC160AHE3/9AT suitable for automotive applications?
Yes, the 1.5SMC160AHE3/9AT is AEC-Q101 qualified, as confirmed by the "HE3" suffix in its part number. It has undergone rigorous stress testing-including temperature cycling, highly accelerated life testing (HALT), and ESD validation-making it appropriate for under-hood engine control units, ADAS camera modules, and body control modules where reliability under thermal and mechanical stress is mandatory.
How does the 1.5SMC160AHE3/9AT differ from bidirectional variants like 1.5SMC160CA?
The 1.5SMC160AHE3/9AT is unidirectional and features a cathode band marking; it conducts forward current and clamps reverse surges only. In contrast, 1.5SMC160CA is bidirectional with no polarity marking and clamps transients in both directions. The 1.5SMC160AHE3/9AT is used where DC bias exists (e.g., power rails), while the CA version suits AC-coupled or symmetric signal lines.
What is the thermal resistance of the 1.5SMC160AHE3/9AT, and how does it affect PCB layout?
The 1.5SMC160AHE3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-leads resistance (RθJL) of 15 °C/W. To maintain safe operating temperature under repeated surges, PCB layout must use minimum 8.0 mm × 8.0 mm copper pads per terminal, as specified in Vishay's datasheet Figure 2 derating curves-reducing pad size increases thermal impedance and risks premature thermal runaway.
Does the 1.5SMC160AHE3/9AT meet RoHS and halogen-free requirements?
Yes, the "HE3" suffix indicates the 1.5SMC160AHE3/9AT is RoHS-compliant and AEC-Q101 qualified. It is not halogen-free; for halogen-free compliance, the equivalent part is 1.5SMC160AHM3/9AT. Both versions use matte tin-plated leads and meet JESD 201 Class 2 whisker resistance requirements.
