Product details
Overview
SM6T10CAHE3_A/H from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, rated for 10 V standoff voltage (VWM), 12.2 V minimum breakdown voltage (VBR), 600 W peak pulse power (10/1000 μs), and AEC-Q101 qualified for automotive use. It protects signal lines and power rails in sensor interfaces and ECU circuits against inductive switching transients.
For engineers reviewing the SM6T10CAHE3_A/H datasheet, SM6T10CAHE3_A/H pinout, SM6T10CAHE3_A/H application, or SM6T10CAHE3_A/H equivalent, key selection criteria include bidirectional clamping capability, 150 °C junction temperature rating, RoHS-compliant and halogen-free construction, and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering consistent clamping performance regardless of transient polarity. Its glass-passivated junction ensures stable leakage behavior (<1.0 μA at VWM) and robust surge handling up to 100 A IFSM (unidirectional only - not applicable here).
The device uses a low-inductance SMB package optimized for fast transient response, with thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W. It meets J-STD-020 MSL Level 1 and supports reflow peak temperatures up to 260 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR (min) | 12.2 V - guaranteed breakdown starts no lower than this under 1 mA test current |
| VC (max) | 17.0 V - maximum clamping voltage at 35.0 A IPPM (10/1000 μs), limiting protected circuit stress |
| PPPM | 600 W - peak transient energy absorption capacity per single 10/1000 μs pulse |
| TJ max | +150 °C - maximum allowable junction temperature, enabling operation in under-hood automotive environments |

Applications
| Automotive Sensor Protection | Industrial CAN Bus Interface |
|---|---|
Use Scenario: Protecting analog output lines of pressure, temperature, and position sensors in engine control units exposed to load-dump and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional TVS placed between sensor signal line and chassis ground to clamp ± transients before they reach ADC input or signal conditioner. Use Value: Prevents sensor signal corruption and microcontroller reset events caused by >100 V spikes, leveraging 17.0 V clamping at 35 A to keep rail voltage within safe operating range. | Use Scenario: Safeguarding CAN_H and CAN_L differential pair inputs in industrial gateways subjected to EFT and surge per IEC 61000-4-4/5. IC Role / Device Role / Timing Role: Dual-SMB TVS array (one per line) referenced to common ground, suppressing common-mode surges while maintaining signal integrity. Use Value: Maintains CAN bit timing accuracy by limiting voltage excursion to <17.0 V during 35 A transients, avoiding bus lockup or false dominant detection. |
| Consumer USB Port ESD Protection | Telecom Power Rail Clamping |
Use Scenario: Secondary-level ESD protection on USB 2.0 D+ and D− lines in set-top boxes and smart displays where primary TVS resides upstream. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp placed immediately before USB transceiver I/O pins to absorb contact discharge events. Use Value: Delivers sub-1 ns response time and <1.0 μA leakage at 10 V, preventing data corruption without loading high-speed signaling paths. | Use Scenario: Overvoltage suppression on 12 V DC input rails of VoIP phones and DSL modems during lightning-induced surges on PoE or external power adapters. IC Role / Device Role / Timing Role: Parallel-connected TVS across input capacitor to shunt transient energy before it reaches DC-DC converter input stage. Use Value: Absorbs 600 W pulses without degradation, ensuring uninterrupted operation during 10/1000 μs surges up to 35 A, validated per AEC-Q101 stress profiles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA | Same SMB package, 600 W rating, but VBR min = 11.1 V and VC max = 17.0 V at 34.4 A; non-AEC-Q101 qualified | Lacks automotive qualification; suitable for commercial/industrial use only | Select when AEC-Q101 compliance is not required and cost sensitivity outweighs qualification needs |
| 1.5KE10CA | Higher-power DO-204AC (Axial) package, 1500 W rating, VBR min = 8.55 V, VC max = 14.5 V at 103 A; leaded, through-hole only | Requires PCB real estate and assembly process change; not SMT-compatible | Choose only if system-level surge requirements exceed 600 W and board layout permits axial components |
Compared with SMAJ10CA and 1.5KE10CA, SM6T10CAHE3_A/H uniquely combines AEC-Q101 qualification, SMB SMT compatibility, and precise 10 V standoff in a single solution-enabling drop-in replacement in automotive ECUs without derating or layout revision.

FAQ
What does the "CA" suffix indicate in SM6T10CAHE3_A/H?
The "CA" suffix denotes a bidirectional configuration, meaning SM6T10CAHE3_A/H provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., SM6T10A), it has no cathode marking and functions identically regardless of polarity applied across its terminals, making it ideal for AC-coupled or floating signal lines.
Is SM6T10CAHE3_A/H suitable for automotive applications?
Yes, SM6T10CAHE3_A/H is AEC-Q101 qualified and carries the "HE3" suffix indicating RoHS-compliant and automotive-grade construction. It undergoes rigorous stress testing-including temperature cycling, high-temperature reverse bias, and ESD-validating its use in engine control units, ADAS sensors, and body electronics where ambient temperatures reach +125 °C and transients exceed 100 V.
What is the maximum clamping voltage of SM6T10CAHE3_A/H at rated peak pulse current?
The maximum clamping voltage (VC) of SM6T10CAHE3_A/H is 17.0 V when subjected to its rated peak pulse current of 35.0 A under the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and ensures protected circuitry remains below critical overvoltage thresholds during surge events.
How does the SMB (DO-214AA) package of SM6T10CAHE3_A/H affect PCB layout?
The SMB package of SM6T10CAHE3_A/H requires a minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad area per terminal to maintain thermal performance and achieve rated 600 W pulse power. Its 0.220" × 0.130" footprint supports high-density SMT placement, and its MSL Level 1 rating eliminates pre-reflow baking requirements-simplifying manufacturing flow for SM6T10CAHE3_A/H integration.
Does SM6T10CAHE3_A/H have a specified junction capacitance?
No, the official Vishay datasheet for SM6T10CAHE3_A/H does not specify junction capacitance (CJ). While typical CJ values for SMB-packaged TVS diodes in this series fall between 100–500 pF depending on voltage rating, CJ is not characterized or guaranteed for SM6T10CAHE3_A/H in the published documentation and must be measured empirically if required for high-speed signal line design.
