Product details
Overview
1.5SMC200CAHE3_A/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 200 V standoff voltage (VWM), 220 V minimum breakdown voltage (VBR), 1500 W peak pulse power (10/1000 µs), clamping voltage of 328 V at 4.6 A, and operates across –65 °C to +150 °C. It is used in automotive sensor interfaces and industrial I/O protection where lightning- and ESD-induced transients must be suppressed without compromising signal integrity.
For engineers reviewing the 1.5SMC200CAHE3_A/I datasheet, 1.5SMC200CAHE3_A/I pinout, 1.5SMC200CAHE3_A/I application, or 1.5SMC200CAHE3_A/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMC (DO-214AB) package compatibility, and verified performance under 10/1000 µs surge waveforms per IEC 61000-4-5.
Technical Context
This device implements a silicon avalanche diode structure with glass-passivated junction, enabling sub-nanosecond response to voltage transients. Its bidirectional architecture allows symmetrical clamping in AC-coupled or floating signal paths without polarity constraints.
Rated for 1500 W peak pulse power at 10/1000 µs, it delivers 328 V clamping voltage at 4.6 A IPPM while maintaining low incremental surge resistance and thermal resistance of 75 °C/W (junction-to-ambient). It meets MSL Level 1 and is qualified to AEC-Q101 for automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 200 V - Maximum continuous reverse working voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown, min) | 220 V at 1 mA - Guaranteed avalanche initiation voltage; ensures reliable turn-on during overvoltage events. |
| VC (Clamping) | 328 V at 4.6 A IPPM - Peak voltage seen by protected circuit during 10/1000 µs surge; determines stress on downstream components. |
| PPPM | 1500 W - Surge energy handling capacity under standardized waveform; supports IEC 61000-4-5 Level 4 compliance. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in high-ambient environments such as automotive engine compartments. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47. |
| Package | SMC (DO-214AB) - Surface-mount outline with 8.0 mm × 8.0 mm copper pad requirement; supports automated placement and reflow. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL Level 1, 260 °C lead-free reflow compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; common reference point in bidirectional configuration | No polarity marking; symmetric terminals enable AC line protection without orientation dependency. |
| Cathode | Current exit terminal in forward bias; common reference point in bidirectional configuration | Identical physical terminal to Anode; bidirectional operation eliminates cathode/anode distinction in layout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | Lower peak power rating (600 W), same VWM/VC, SMB package (smaller thermal mass) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 or automotive load dump | Select when board space is constrained and surge threat level is limited to IEC 61000-4-4 Level 3. |
| 1.5KE200CA | Through-hole TO-218 package, identical electrical specs but higher RθJA (100 °C/W) and no AEC-Q101 qualification | Not suitable for automated SMT production or automotive under-hood use due to package and qualification gap | Choose only for legacy through-hole designs where rework flexibility outweighs AEC-Q101 and thermal performance needs. |
Compared with SMBJ200CA and 1.5KE200CA, the 1.5SMC200CAHE3_A/I uniquely combines AEC-Q101 qualification, 1500 W surge capability, and SMC surface-mount compatibility-making it the only option qualified for high-reliability automotive and industrial SMT applications requiring full IEC 61000-4-5 compliance.

FAQ
What is the clamping voltage of the 1.5SMC200CAHE3_A/I at its rated peak pulse current?
The 1.5SMC200CAHE3_A/I has a maximum clamping voltage (VC) of 328 V at 4.6 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet 88303 and defines the upper voltage limit imposed on protected circuitry during surge events. The 1.5SMC200CAHE3_A/I maintains this clamping performance across its specified operating temperature range.
Is the 1.5SMC200CAHE3_A/I suitable for automotive applications?
Yes, the 1.5SMC200CAHE3_A/I is AEC-Q101 qualified (indicated by the "HE3" suffix) and rated for operation from –65 °C to +150 °C, making it suitable for automotive under-hood and chassis-mounted applications. It is specifically validated for temperature cycling, high-temperature reverse bias, and mechanical shock per AEC-Q101 requirements. The 1.5SMC200CAHE3_A/I is commonly deployed in engine control units, ADAS sensor interfaces, and body electronics.
What does the "CA" suffix mean in 1.5SMC200CAHE3_A/I?
The "CA" suffix in 1.5SMC200CAHE3_A/I denotes a bidirectional configuration-meaning the device provides symmetrical transient suppression for both polarities of voltage transients. Unlike unidirectional variants (e.g., "A"), the 1.5SMC200CAHE3_A/I has no cathode marking and functions identically in either orientation, simplifying layout for AC-coupled or floating signal lines. This is confirmed in the Vishay 1.5SMC Series datasheet section "DEVICES FOR BIDIRECTION APPLICATIONS".
What is the thermal resistance of the 1.5SMC200CAHE3_A/I, and how does it affect PCB layout?
The 1.5SMC200CAHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, as specified in the Vishay datasheet. To achieve this rating, PCB layout must provide minimum recommended pad area and thermal vias to internal ground planes. Insufficient copper reduces heat dissipation and may cause premature thermal failure during repetitive surge events.
How does the 1.5SMC200CAHE3_A/I compare to the 1.5SMC200A variant?
The 1.5SMC200CAHE3_A/I is bidirectional with AEC-Q101 qualification and RoHS-compliant HE3 packaging, whereas the 1.5SMC200A is unidirectional, commercial-grade, and lacks automotive qualification. Their electrical parameters (VWM, VBR, VC) differ: the 1.5SMC200A has VWM = 171 V and VC = 274 V, while the 1.5SMC200CAHE3_A/I has VWM = 200 V and VC = 328 V. The 1.5SMC200CAHE3_A/I is not a drop-in replacement for the 1.5SMC200A due to polarity and qualification differences.
