Product details
Overview
SM6T6V8AHM3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, rated for 600 W peak pulse power (10/1000 μs), 6.45–7.14 V breakdown voltage at 10 mA, 5.80 V stand-off voltage, and 10.5 V clamping voltage at 57 A peak pulse current. It protects MOSFETs and ICs against inductive switching transients in automotive sensor signal lines.
For engineers reviewing the SM6T6V8AHM3_A/I datasheet, SM6T6V8AHM3_A/I pinout, SM6T6V8AHM3_A/I application, or SM6T6V8AHM3_A/I equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, SMB package thermal data, and real-world protection use cases - all confirmed from Vishay's official SM6T series documentation (Doc. #88385, Rev. 09-Jan-2024).
Technical Context
The SM6T6V8AHM3_A/I operates as a unidirectional clamping device with glass-passivated junction, optimized for low-inductance surge suppression. Its 100 °C/W junction-to-ambient thermal resistance and 20 °C/W junction-to-lead resistance support reliable operation under repetitive transient stress when mounted on 5.0 mm × 5.0 mm copper pads.
Designed for automotive-grade reliability, the HM3 suffix confirms halogen-free, RoHS-compliant construction and AEC-Q101 qualification. Polarity is marked by cathode band; reverse leakage is limited to 1000 μA at 5.80 V stand-off, ensuring minimal standby power loss in always-on sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 600 W - sustains high-energy transients without failure in automotive load-dump or ISO 7637-2 pulse 5a scenarios |
| Breakdown Voltage VBR | 6.45–7.14 V at 10 mA - ensures precise turn-on before downstream IC damage threshold (e.g., 5.5 V logic rails) |
| Stand-off Voltage VWM | 5.80 V - blocks normal operating voltage while remaining fully inactive during 5 V system bias |
| Clamping Voltage VC | 10.5 V at 57 A - limits voltage seen by protected circuit to safe margin below absolute maximum ratings of typical 12 V interface ICs |
| Operating Temperature | −65 °C to +150 °C - supports under-hood deployment in automotive engine control modules |
| Package | SMB (DO-214AA) - surface-mount footprint compatible with automated placement and meets UL 94 V-0 flammability |

Applications
| Automotive Sensor Protection | CAN Bus Transient Suppression |
|---|---|
Use Scenario: Protecting analog output of pressure or temperature sensors in engine bay environments subject to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor output pin and ground to clamp negative-going transients and limit positive excursions. Use Value: Maintains signal integrity below 10.5 V clamping level, preventing ADC saturation or op-amp rail-to-rail latch-up during 12 V system surges. |
Use Scenario: Safeguarding CAN transceiver I/O pins against ESD and coupled noise from adjacent high-current wiring in vehicle body control modules. IC Role / Device Role / Timing Role: Standoff-clamp TVS on CAN_H and CAN_L lines, referenced to ground, absorbing fast transients without distorting differential signaling. Use Value: Preserves CAN bit timing integrity by limiting overshoot to ≤10.5 V, avoiding false dominant detection or bus lockup during ISO 10605 ESD events. |
| Industrial PLC Input Protection | Consumer Appliance Motor Driver Interface |
Use Scenario: Shielding 24 V digital input channels in programmable logic controllers from relay coil flyback and field wiring surges. IC Role / Device Role / Timing Role: Unidirectional clamping diode installed across input optocoupler anode and ground to shunt inductive kickback. Use Value: Enables robust 24 V DC input operation with <1 μs response time, eliminating need for external RC snubbers in space-constrained DIN-rail enclosures. |
Use Scenario: Protecting microcontroller GPIOs driving half-bridge gate drivers in washing machine motor control boards exposed to brush-commutator noise. IC Role / Device Role / Timing Role: Low-leakage (1000 μA max) TVS on gate drive signal path to prevent false turn-on during commutation spikes. Use Value: Prevents unintended MOSFET switching by clamping gate-source transients to <10.5 V, reducing risk of shoot-through and thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.8A-E3/52 | Same SMB package, 6.8 V nominal VBR, but only commercial grade (not AEC-Q101 qualified); 400 W PPPM rating | Lacks automotive qualification and lower surge capability - suitable for industrial or consumer PCBs without automotive compliance needs | Select when cost sensitivity outweighs AEC-Q101 requirement and surge energy remains below 400 W |
| 1.5SMC6.8A | Higher-power SMC package (1500 W PPPM), same 6.8 V VBR range, but larger footprint (7.11 mm × 6.22 mm vs. SMB's 4.57 mm × 3.94 mm) | Used where higher surge margin is needed (e.g., alternator output lines), but requires PCB layout change due to larger pad area | Choose when system-level surge testing exceeds 600 W and board space allows SMC footprint |
Compared with SMAJ6.8A-E3/52 and 1.5SMC6.8A, the SM6T6V8AHM3_A/I uniquely combines AEC-Q101 qualification, 600 W capability, and SMB footprint - making it the optimal choice for space-constrained automotive sensor nodes requiring certified reliability without layout redesign.

FAQ
What is the exact breakdown voltage range for SM6T6V8AHM3_A/I?
The SM6T6V8AHM3_A/I has a specified breakdown voltage (VBR) range of 6.45 V to 7.14 V at 10 mA test current, per Vishay's SM6T series datasheet (Doc. #88385). This range ensures consistent clamping behavior across production lots and supports design margining for 5 V and 12 V systems. The value is measured using a 300 μs square-wave pulse, confirming stability under transient conditions.
Is SM6T6V8AHM3_A/I qualified for automotive applications?
Yes, SM6T6V8AHM3_A/I is AEC-Q101 qualified, as indicated by the "HM3" suffix (halogen-free, RoHS-compliant, and AEC-Q101 qualified). It undergoes full stress testing including high-temperature operating life, temperature cycling, and ESD per JEDEC standards - making it suitable for engine control units, body electronics, and ADAS sensor modules.
What does the "_A/I" suffix mean in SM6T6V8AHM3_A/I?
The "_A/I" suffix in SM6T6V8AHM3_A/I denotes the revision code ("A") and packaging format ("I" = 13-inch tape and reel, 3200 units per reel). This matches Vishay's ordering convention where "I" indicates large-reel delivery for high-volume SMT production, and "A" reflects the latest documented revision per datasheet revision history (09-Jan-2024).
What is the maximum clamping voltage of SM6T6V8AHM3_A/I at rated peak pulse current?
The SM6T6V8AHM3_A/I clamps to a maximum of 10.5 V at its rated peak pulse current of 57 A (10/1000 μs waveform), as specified in the Electrical Characteristics table. This low clamping voltage ensures protected circuits - such as 5 V microcontrollers or CAN transceivers - remain within safe operating limits during surge events.
Can SM6T6V8AHM3_A/I replace SM6T6V8A-E3/52 in existing designs?
SM6T6V8AHM3_A/I can replace SM6T6V8A-E3/52 electrically and mechanically - both use SMB (DO-214AA) package and share identical VBR, VWM, and VC specs. However, SM6T6V8AHM3_A/I adds AEC-Q101 qualification and halogen-free construction, making it suitable for automotive upgrades without layout changes.
