Product details
Overview
1.5SMC160AHE3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 160 V standoff voltage (VWM), 179 V minimum breakdown voltage (VBR), 219 V maximum clamping voltage (VC) at 6.8 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive ECUs, industrial motor drives, and telecom power supplies.
For engineers reviewing the 1.5SMC160AHE3/57T datasheet, 1.5SMC160AHE3/57T pinout, 1.5SMC160AHE3/57T application, or 1.5SMC160AHE3/57T equivalent, key selection criteria include clamping performance under repetitive surge conditions, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and compatibility with SMC (DO-214AB) PCB footprints.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging an avalanche breakdown mechanism to divert transient energy away from sensitive downstream circuitry. Its glass-passivated junction ensures stable reverse leakage (<1.0 μA at VWM) and fast response time (<1.0 ps), critical for protecting MOSFET gates and microcontroller I/O pins against ESD and inductive switching spikes.
The device is rated for continuous operation from –65 °C to +150 °C junction temperature, with derated peak pulse power above 25 °C per Fig. 2 of the datasheet. Mounting on 8.0 mm × 8.0 mm copper pads enables effective heat dissipation, supporting its 6.5 W steady-state power dissipation rating and 200 A non-repetitive forward surge current capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 152–168 V at 1.0 mA - Confirmed avalanche initiation 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 for standardized lightning/surge waveforms; validates suitability for IEC 61000-4-5 Level 4. |
| RθJA | 75 °C/W - Thermal resistance from junction to ambient; informs heatsinking requirements for sustained surge duty cycles. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22 standards. |
| Package | SMC (DO-214AB) - Industry-standard surface-mount outline with cathode band marking; compatible with automated pick-and-place. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL level 1 (260 °C reflow peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | High-side connection in unidirectional configuration | Connected to protected line (e.g., 12 V rail); conducts surge current toward ground when voltage exceeds VBR. |
| Anode | Low-side reference terminal | Typically tied to system ground or low-impedance return path; completes clamping loop during transient events. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 μs) | Enables single-device protection against IEC 61000-4-5 surges up to 4 kV (open-circuit) without cascaded stages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-E3/57T | Lower PPPM (400 W), same VWM (136 V), larger package (SMA/DO-214AC), higher RθJA (110 °C/W) | Restricted to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 or automotive load dump. | Select only if board space allows SMA footprint and surge requirements are ≤400 W. |
| 1.5KE160A-T | Through-hole (DO-201AD), identical VWM/VC specs, but no AEC-Q101 qualification and MSL level 2 (245 °C peak) | Not suitable for automated SMT production or automotive under-hood environments requiring AEC-Q101 compliance. | Use only for prototyping or legacy through-hole designs where reflow compatibility is not required. |

FAQ
What is the clamping voltage of the 1.5SMC160AHE3/57T under a 10/1000 μs surge?
The 1.5SMC160AHE3/57T exhibits a maximum clamping voltage (VC) of 219 V when subjected to its rated peak pulse current of 6.8 A using the standardized 10/1000 μs waveform. This value is measured per Figure 1 and Table 1 of the Vishay datasheet 88303 and defines the upper voltage limit imposed on protected circuitry during surge events. The 1.5SMC160AHE3/57T maintains this clamping performance across its specified operating temperature range.
Is the 1.5SMC160AHE3/57T qualified for automotive applications?
Yes, the 1.5SMC160AHE3/57T carries the HE3 suffix, indicating full AEC-Q101 qualification per Vishay's documentation. It has undergone stress testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD per JESD22 standards, validating its use in automotive powertrain, body control, and infotainment systems. The 1.5SMC160AHE3/57T is explicitly listed in the "AEC-Q101 qualified available" section of datasheet 88303.
What does the "HE3/57T" suffix mean in 1.5SMC160AHE3/57T?
The "HE3" denotes RoHS-compliant construction with AEC-Q101 qualification, while "57T" specifies packaging in a 7-inch diameter plastic tape-and-reel format containing 850 units. This ordering code aligns with Vishay's documented format in the "Ordering Information" table on page 3 of datasheet 88303. The 1.5SMC160AHE3/57T thus combines automotive-grade reliability with SMT-ready packaging for high-volume manufacturing.
How does the thermal performance of the 1.5SMC160AHE3/57T compare to similar TVS diodes?
The 1.5SMC160AHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads - significantly lower than SMA-package alternatives like SMAJ160A-E3/57T (RθJA = 110 °C/W). This enables higher sustained surge repetition rates and improved reliability in thermally constrained layouts. The 1.5SMC160AHE3/57T datasheet confirms this value in the "Thermal Characteristics" table on page 3.
Can the 1.5SMC160AHE3/57T be used in bidirectional configurations?
No, the 1.5SMC160AHE3/57T is a unidirectional TVS diode, as indicated by the "A" suffix and absence of "CA" in its part number. Bidirectional variants (e.g., 1.5SMC160CA) are separately specified with symmetrical breakdown in both polarities. Using the 1.5SMC160AHE3/57T in reverse-biased configurations risks permanent damage due to lack of reverse avalanche capability. The 1.5SMC160AHE3/57T polarity is marked by a cathode band per the mechanical drawing on page 5.
