Product details
Overview
SM6T10CAHE3_A/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, rated for 600 W peak pulse power (10/1000 μs), 10 V standoff voltage (VWM), and 14.5 V clamping voltage (VC) at peak pulse current. It provides robust ESD and surge protection for signal lines in automotive sensor units and industrial control interfaces.
For engineers reviewing the SM6T10CAHE3_A/I datasheet, SM6T10CAHE3_A/I pinout, SM6T10CAHE3_A/I application, or SM6T10CAHE3_A/I equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification, 100 °C/W junction-to-ambient thermal resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
The SM6T10CAHE3_A/I operates as a symmetric bidirectional TVS, with identical breakdown (VBR min = 9.5 V, max = 10.5 V) and clamping characteristics in both polarities. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and low inductance for fast transient response.
Designed for IEC 61000-4-2 (ESD) and IEC 61000-4-5 (surge) compliance, it delivers 600 W peak pulse power handling under standardized 10/1000 μs waveform conditions, with thermal derating above 25 °C per Fig. 2 and maximum junction temperature of +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 9.5 V / 10.5 V - Breakdown voltage range at 1.0 mA test current, confirming bidirectional symmetry |
| VC @ IPPM | 14.5 V - Clamping voltage at peak pulse current, limiting downstream voltage stress during transients |
| PPPM | 600 W - Peak pulse power dissipation capability with 10/1000 μs waveform, defining surge robustness |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads, guiding PCB thermal layout |
| TJ max. | +150 °C - Maximum allowable junction temperature, supporting operation in under-hood automotive environments |
| ID @ VWM | ≤1.0 μA - Reverse leakage current at standoff voltage, minimizing standby power loss in high-impedance circuits |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; meets UL 94 V-0 flammability rating and MSL level 1 (260 °C peak reflow).

Applications
| Automotive Sensor Protection | Industrial CAN Bus Interface |
|---|---|
Use Scenario: Protecting LIN/CAN transceiver inputs and analog sensor outputs (e.g., pressure, temperature) from load-dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point to shunt surge energy before reaching sensitive IC pins.

IC Role / Device Role / Timing Role: Common-mode TVS pair (one per line) providing symmetrical clamping without disrupting DC bias or signal swing. Use Value: Enables reliable 1 Mbps CAN communication under harsh EMC conditions due to matched bidirectional VBR and low clamping overshoot. |
| Consumer USB Data Lines | Telecom Power Supply Input |
Use Scenario: ESD protection for USB 2.0 D+/D− lines in portable devices where space and low capacitance are critical. IC Role / Device Role / Timing Role: Low-capacitance (typ. <100 pF at 0 V) bidirectional clamp placed adjacent to connector to absorb ±8 kV contact discharge. Use Value: Prevents data corruption and interface IC damage without degrading signal rise/fall times, compliant with IEC 61000-4-2 Level 4. | Use Scenario: Secondary-side transient suppression on 12 V or 24 V telecom power rails feeding FPGA or DSP modules. IC Role / Device Role / Timing Role: Standoff-rated (10 V) TVS placed after DC/DC converter output to absorb residual switching spikes and lightning-induced surges. Use Value: Limits rail excursions to ≤14.5 V during 600 W transients, preventing brownout resets and latch-up in downstream logic. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | Same SMB package, 600 W rating, but VWM = 10 V, VBR = 11.1–12.3 V, VC = 17.0 V - higher clamping voltage | Less effective clamping margin for 12 V systems; may allow higher downstream stress | Select SM6T10CAHE3_A/I when tighter clamping (14.5 V vs. 17.0 V) and AEC-Q101 qualification are required |
| 1.5KE10CA | Through-hole DO-201 package, same VWM/VBR/VC specs, but 1500 W rating and higher RθJA - larger footprint, lower power density | Not suitable for high-density SMT designs; requires manual or wave soldering | Choose SM6T10CAHE3_A/I for automated assembly, space-constrained PCBs, and automotive production environments |
Compared with SMBJ10CA and 1.5KE10CA, the SM6T10CAHE3_A/I offers superior clamping performance in a compact AEC-Q101-qualified SMT package, making it optimal for automotive and industrial applications demanding high reliability, low voltage overshoot, and seamless integration into automated manufacturing flows.

FAQ
What is the clamping voltage of the SM6T10CAHE3_A/I under a 10/1000 μs surge?
The SM6T10CAHE3_A/I has a maximum clamping voltage (VC) of 14.5 V when subjected to its rated peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88385 and defines the upper voltage limit imposed on protected circuitry during surge events. The SM6T10CAHE3_A/I maintains this clamping performance bidirectionally, ensuring consistent protection regardless of transient polarity.
Is the SM6T10CAHE3_A/I qualified for automotive applications?
Yes, the SM6T10CAHE3_A/I is AEC-Q101 qualified, as confirmed by its HE3 suffix and documentation in Vishay's SM6T series datasheet (Rev. 09-Jan-2024, Doc. #88385). This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD, validating its suitability for under-hood and chassis-mounted automotive electronics. The SM6T10CAHE3_A/I is explicitly designated for automotive use in the ordering information table.
What is the standoff voltage (VWM) and why does it matter for SM6T10CAHE3_A/I?
The SM6T10CAHE3_A/I has a standoff voltage (VWM) of 10 V, meaning it remains non-conductive up to this reverse voltage level during normal operation. This parameter ensures minimal leakage current (<1.0 μA) and avoids interference with 12 V nominal systems where transient margins are tight. Selecting the correct VWM prevents false triggering while maintaining sufficient headroom above operating voltage - a critical factor in designing robust SM6T10CAHE3_A/I protection networks.
Does the SM6T10CAHE3_A/I have polarity markings on the package?
No, the SM6T10CAHE3_A/I does not have polarity markings because it is a bidirectional TVS diode. Unlike unidirectional variants (e.g., SM6T10A), the CA-suffixed version features symmetric electrical characteristics in both directions, eliminating the need for cathode band identification. This simplifies board layout and eliminates orientation errors during automated placement - a verified design feature documented in the "Polarity" section of the Vishay SM6T datasheet.
What is the thermal resistance of the SM6T10CAHE3_A/I and how does it affect PCB layout?
The SM6T10CAHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay datasheet. This value directly informs minimum pad area and copper pour requirements: reducing thermal resistance requires increasing copper area or adding thermal vias. Proper implementation ensures the SM6T10CAHE3_A/I stays within its +150 °C maximum junction temperature during repetitive surge events.
