Product details
Overview
SM6T10CAHE3/5B from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, rated for 10 V standoff voltage (VWM), 12.8 V minimum breakdown voltage (VBR), and 600 W peak pulse power (10/1000 μs). It clamps transients to ≤17.0 V at 35.0 A peak pulse current and operates from −65 °C to +150 °C, protecting signal lines in automotive sensor units and industrial I/O interfaces.
For engineers reviewing the SM6T10CAHE3/5B datasheet, SM6T10CAHE3/5B pinout, SM6T10CAHE3/5B application, or SM6T10CAHE3/5B equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 17.0 V max clamping voltage at rated IPPM, RoHS-compliant matte tin terminals, and compatibility with automated SMT placement on standard SMB footprints.
Technical Context
The SM6T10CAHE3/5B implements a glass-passivated silicon junction optimized for fast response (<1 ns) to ESD and surge events. Its bidirectional architecture enables symmetrical clamping in both polarities without external polarity management, supporting protection of AC-coupled or differential signal paths.
Designed per J-STD-020 MSL Level 1, it withstands reflow peak temperatures up to 260 °C and exhibits low parasitic inductance due to its compact SMB package geometry and internal leadframe design - critical for maintaining clamping integrity during high-di/dt transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before conduction begins; defines safe signal swing margin in protected circuit. |
| VBR (min) | 12.8 V - Minimum breakdown voltage at 1 mA test current; ensures reliable turn-on above normal operating voltage. |
| VC @ IPPM | 17.0 V - Max clamping voltage at 35.0 A (10/1000 μs); determines worst-case overvoltage seen by downstream ICs. |
| PPPM | 600 W - Peak pulse power handling (10/1000 μs); supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-to-line). |
| TJ range | −65 °C to +150 °C - Full automotive-grade junction temperature range; validated for under-hood and engine-control module use. |
| Package | SMB (DO-214AA) - Standard surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with IPC-7351B generic land pattern. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case meeting UL 94 V-0 flammability rating; matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; no polarity marking (bidirectional device).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional transient path | No functional polarity - either terminal serves as anode or cathode depending on instantaneous voltage polarity; enables single-device protection of AC or floating nodes. |
| Case / Body | Thermal and mechanical interface | Non-conductive molded body; thermal path relies on copper pad area (0.2" × 0.2") per terminal per datasheet derating curves. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables robust protection against IEC 61000-4-5 surges up to 4 kV without degradation across full temperature range. |
| AEC-Q101 qualified | Validated for automotive applications including powertrain, chassis, and ADAS sensor interfaces per stress test requirements. |
| Low clamping ratio (VC/VBR ≈ 1.33) | Minimizes overvoltage stress on protected ICs - e.g., 17.0 V clamp limits damage to 3.3 V or 5 V logic inputs. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and single-reflow processing without baking; reduces manufacturing overhead in high-volume SMT lines. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN FD and LIN bus transceivers from load dump and ISO 7637-2 pulses in vehicle door modules and seat control units. IC Role / Device Role / Timing Role: Bidirectional TVS placed across differential bus lines to clamp ±200 V transients within <1 ns.

IC Role / Device Role / Timing Role: Primary-level TVS mounted at board edge to absorb multi-kA 10/1000 μs surges before reaching isolation transformers. Use Value: Withstands repeated 600 W pulses without parameter shift - verified over 1000 surges at 80 % of rated IPPM per JEDEC standards. |
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 SMB package, 600 W rating, but VWM = 10 V, VC = 17.0 V - identical clamping; not AEC-Q101 qualified. | Lacks automotive qualification; suitable for commercial/industrial only; no HE3 suffix indicating AEC-Q101 compliance. | Select when AEC-Q101 is not required and cost optimization is prioritized over automotive traceability. |
| 1.5KE10CA | Higher-power through-hole part (1500 W), DO-201 package; VWM = 10 V, VC = 17.0 V - same clamping but larger footprint and lower SMT compatibility. | Requires PCB redesign for axial/through-hole mounting; unsuitable for space-constrained or fully automated assembly. | Choose only if system-level surge requirements exceed 600 W or legacy through-hole design mandates. |
Compared with SMAJ10CA and 1.5KE10CA, the SM6T10CAHE3/5B uniquely combines AEC-Q101 qualification, SMB surface-mount compatibility, and guaranteed 600 W surge handling - making it the preferred choice for next-generation automotive ECUs and high-reliability industrial controllers where qualification, size, and process compatibility are jointly critical.

FAQ
What is the maximum clamping voltage of the SM6T10CAHE3/5B at its rated peak pulse current?
The SM6T10CAHE3/5B has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPPM) of 35.0 A under the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88385 and defines the upper voltage limit imposed on protected circuitry during surge events. The SM6T10CAHE3/5B maintains this clamping performance across its full operating temperature range.
Is the SM6T10CAHE3/5B suitable for automotive applications?
Yes, the SM6T10CAHE3/5B is AEC-Q101 qualified, as confirmed by its HE3 suffix and documentation in Vishay's SM6T datasheet (Rev. 09-Jan-2024, Doc. #88385). It is explicitly rated for automotive use including engine control, body electronics, and ADAS sensor interfaces. The SM6T10CAHE3/5B undergoes stress testing per AEC-Q101 requirements and supports junction temperatures up to +150 °C.
What does the "CA" suffix indicate in SM6T10CAHE3/5B?
The "CA" suffix in SM6T10CAHE3/5B denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions without polarity dependence. This distinguishes it from unidirectional variants (e.g., SM6T10A) and enables protection of AC-coupled, differential, or floating signal lines. The SM6T10CAHE3/5B has no polarity marking on its SMB package.
What is the standoff voltage (VWM) rating for the SM6T10CAHE3/5B?
The SM6T10CAHE3/5B has a standoff voltage (VWM) of 10 V, representing the maximum DC or continuous reverse operating voltage that can be applied without significant leakage current. At this voltage, reverse leakage current is specified at ≤1.0 μA. This rating ensures compatibility with 12 V automotive systems and 10 V industrial signal rails while allowing sufficient margin before breakdown at 12.8 V minimum VBR.
Does the SM6T10CAHE3/5B require special PCB layout considerations?
Yes - the SM6T10CAHE3/5B requires mounting on minimum recommended copper pad areas of 0.2" × 0.2" (5.0 mm × 5.0 mm) per terminal to meet its 600 W peak pulse power rating and thermal derating curves. Short, direct traces to ground or protected node are essential to minimize inductance; the SM6T10CAHE3/5B's low-inductance SMB package is only effective when layout parasitics are controlled per Vishay's application guidance in document 88385.
