Product details
Overview
SM6T10CAHE3/52 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 10 V stand-off voltage (VWM), 11.3 V minimum breakdown voltage (VBR), 600 W peak pulse power (10/1000 μs), 16.7 V maximum clamping voltage at rated IPPM, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SM6T10CAHE3/52 datasheet, SM6T10CAHE3/52 pinout, SM6T10CAHE3/52 application, or SM6T10CAHE3/52 equivalent, this device is selected for robust ESD and surge protection in automotive sensor interfaces, industrial I/O lines, and DC power rail conditioning where low clamping voltage and high reliability under repetitive transients are required.
Technical Context
The SM6T10CAHE3/52 operates as a symmetrical bidirectional TVS, with identical electrical characteristics in both polarities due to its CA suffix designation. Its silicon junction is glass passivated, enabling stable leakage performance and low inductance (<1 nH typical), critical for fast transient response.
It delivers 600 W peak pulse power per the 10/1000 μs waveform standard, with thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W, supporting operation from –65 °C to +150 °C junction temperature. The device is qualified to AEC-Q101 and meets J-STD-020 MSL Level 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before significant conduction begins; defines safe operating margin for 12 V automotive systems. |
| VBR (min) | 11.3 V - Minimum breakdown voltage at 1 mA test current; ensures reliable triggering above normal operating voltage. |
| VC (max) | 16.7 V - Maximum clamping voltage at rated IPPM (36 A); limits protected circuit stress during 600 W transient events. |
| PPPM | 600 W - Peak pulse power handling capability with 10/1000 μs waveform; supports IEC 61000-4-5 Level 4 surge immunity. |
| TJ max | +150 °C - Maximum junction temperature; enables deployment in under-hood automotive environments without derating. |
| Package | SMB (DO-214AA) - Surface-mount package with 0.220" x 0.130" footprint; compatible with automated pick-and-place and reflow soldering. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
Pinout & Package
SM6T10CAHE3/52 is a bidirectional TVS diode in SMB (DO-214AA) package with no polarity marking; both terminals are functionally symmetric. The case is molded with UL 94 V-0 flammability rating, and terminals are matte tin plated for J-STD-002 solderability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA | Same VWM (10 V), lower PPPM (400 W), larger SMA package (DO-214AC), higher RθJA (150 °C/W) | Limited to lower-energy transients; less suitable for automotive load dump where 600 W is required | Select SMAJ10CA only if board space allows larger footprint and surge energy is capped at 400 W. |
| 1.5KE10CA | Same VWM (10 V), higher PPPM (1500 W), axial-leaded DO-15 package, not surface-mountable | Requires through-hole assembly; incompatible with automated SMT lines and high-density layouts | Choose 1.5KE10CA only for prototyping or legacy through-hole designs where rework tolerance outweighs production efficiency. |
Compared with SMAJ10CA and 1.5KE10CA, SM6T10CAHE3/52 uniquely balances 600 W surge capability, SMB surface-mount compatibility, AEC-Q101 qualification, and low-profile packaging-making it the preferred choice for volume automotive and industrial SMT production where reliability, footprint, and process compatibility are jointly constrained.

FAQ
What is the clamping voltage of SM6T10CAHE3/52 at its rated peak pulse current?
The SM6T10CAHE3/52 has a maximum clamping voltage (VC) of 16.7 V when subjected to its rated peak pulse current (IPPM) of 36 A under the standardized 10/1000 μs waveform. This value is measured per Figure 1 and Table 1 in Vishay Document 88385 and reflects worst-case conduction behavior during surge events, ensuring downstream circuits remain within safe voltage margins.
Is SM6T10CAHE3/52 suitable for automotive applications?
Yes, SM6T10CAHE3/52 is explicitly AEC-Q101 qualified, as confirmed by its HE3 suffix and documentation in Vishay's SM6T datasheet (Rev. 09-Jan-2024). It undergoes rigorous stress testing-including temperature cycling, high-temperature reverse bias, and ESD-to meet automotive reliability requirements for under-hood and chassis-mounted electronics.
Does SM6T10CAHE3/52 have polarity markings on the package?
No, SM6T10CAHE3/52 is a bidirectional TVS diode and carries no cathode band or polarity marking on its SMB (DO-214AA) package. Its symmetrical construction means either terminal functions identically, simplifying layout and eliminating orientation errors during automated assembly.
What is the maximum operating temperature for SM6T10CAHE3/52?
The SM6T10CAHE3/52 supports an operating junction temperature range of –65 °C to +150 °C, as specified in the Absolute Maximum Ratings table of Vishay Document 88385. This wide range enables deployment in extreme environments such as engine control units, power inverters, and outdoor industrial enclosures.
How does the SMB package of SM6T10CAHE3/52 compare to SMA in terms of thermal performance?
The SMB package of SM6T10CAHE3/52 offers lower thermal resistance than SMA: RθJL = 20 °C/W versus ~30–35 °C/W for SMA variants. Combined with its 100 °C/W RθJA, this enables more efficient heat dissipation in high-density layouts, particularly when mounted on 0.2" × 0.2" copper pads per Vishay's recommended pad layout.
