Product details
Overview
SM6T6V8AHE3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping ESD and surge transients on power/signal lines. It features 6.45 V to 7.14 V breakdown voltage (VBR), 5.80 V stand-off voltage (VWM), 10.5 V max clamping voltage at 57 A (10/1000 μs), 600 W peak pulse power, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SM6T6V8AHE3/5B datasheet, SM6T6V8AHE3/5B pinout, SM6T6V8AHE3/5B application, or SM6T6V8AHE3/5B equivalent, key selection criteria include unidirectional polarity, 10.5 V clamping performance at 57 A, SMB footprint compatibility, AEC-Q101 qualification status, and 1000 μA reverse leakage at VWM.
Technical Context
The SM6T6V8AHE3/5B operates as a unidirectional avalanche diode with cathode-band polarity marking, optimized for fast response to transient overvoltages. Its glass-passivated junction ensures stable breakdown behavior and low leakage (≤1000 μA at 5.80 V), while its low-inductance SMB package supports high-frequency surge suppression.
It delivers 600 W peak pulse power under 10/1000 μs waveform per JEDEC standards, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead). Rated for -65 °C to +150 °C operation, it meets MSL Level 1 and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.45 V / 7.14 V - defines reliable avalanche initiation range at 10 mA test current |
| VWM | 5.80 V - maximum continuous reverse operating voltage before leakage exceeds 1000 μA |
| VC @ IPPM | 10.5 V at 57 A - clamping voltage during 600 W transient, limiting downstream stress |
| PPPM | 600 W - peak surge handling capability with 10/1000 μs waveform |
| IFSM | 100 A - non-repetitive forward surge rating (10 ms half-sine), critical for inductive load protection |
| TJ max | +150 °C - enables operation in under-hood automotive environments and industrial enclosures |
| Leakage @ VWM | 1000 μA - low standby current preserves battery life in always-on systems |

|---|---|
Use Scenario: Protecting 5 V supply rails in engine control units (ECUs) and infotainment head units from load-dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between VIN and GND, absorbing energy before it reaches LDOs or microcontrollers. Use Value: Limits clamped voltage to 10.5 V during 57 A surge, preventing latch-up or damage to 5 V-rated ICs per ISO 16750-2. | Use Scenario: Safeguarding analog outputs (e.g., 4–20 mA loops) and digital I/O (CAN/LIN) of industrial temperature/pressure sensors exposed to field wiring surges. IC Role / Device Role / Timing Role: Standoff protection device mounted at connector entry point, shunting transients before signal conditioning circuitry. Use Value: 5.80 V VWM allows full signal swing while 10.5 V VC prevents excursion beyond ADC input limits. |

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-E3/5B | Same SMB package, 6.8 V nominal VBR, but rated for 400 W PPPM and not AEC-Q101 qualified | Lacks automotive qualification; suitable for commercial/industrial only | Select when AEC-Q101 is not required and lower surge margin is acceptable |
| 1.5SMC6.8A | Higher-power SMC package (1500 W), same VBR range, but larger footprint (7.11 mm × 6.22 mm) | Requires PCB layout change; used where higher energy absorption is mandatory | Choose when system-level surge tests exceed 600 W and board space permits larger package |
Compared with SMAJ6.8A-E3/5B and 1.5SMC6.8A, the SM6T6V8AHE3/5B uniquely combines AEC-Q101 qualification, 600 W capability, and SMB footprint-making it optimal for space-constrained automotive and industrial designs requiring validated reliability.

FAQ
What is the breakdown voltage range of the SM6T6V8AHE3/5B?
The SM6T6V8AHE3/5B has a guaranteed breakdown voltage (VBR) range of 6.45 V to 7.14 V at 10 mA test current, measured per JEDEC standards. This tight tolerance ensures predictable clamping onset across production lots and temperature extremes. The SM6T6V8AHE3/5B maintains this specification under AEC-Q101 stress testing, confirming stability in automotive deployments.
Is the SM6T6V8AHE3/5B suitable for automotive applications?
Yes, the SM6T6V8AHE3/5B is AEC-Q101 qualified and explicitly designated for automotive use with ordering code suffix HE3. It undergoes stress testing for temperature cycling, humidity, mechanical shock, and high-temperature operating life per AEC-Q101 Rev D. The SM6T6V8AHE3/5B is deployed in engine control units, body controllers, and ADAS sensors where transient immunity and long-term reliability are critical.
What is the maximum clamping voltage of the SM6T6V8AHE3/5B during a surge event?
The SM6T6V8AHE3/5B clamps to a maximum of 10.5 V at 57 A under the standardized 10/1000 μs double-exponential surge waveform. This value is measured with specified PCB pad layout (0.2" × 0.2" copper) and defines the upper voltage limit imposed on protected circuitry. The SM6T6V8AHE3/5B achieves this with minimal overshoot due to its low-inductance SMB construction.
Does the SM6T6V8AHE3/5B have bidirectional capability?
No, the SM6T6V8AHE3/5B is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional variants in the SM6T family use the "CA" suffix (e.g., SM6T6V8CA). The SM6T6V8AHE3/5B conducts only in reverse avalanche mode and must be oriented with cathode toward the protected line to function correctly.
What packaging format is supplied for the SM6T6V8AHE3/5B?
The SM6T6V8AHE3/5B is supplied in 13-inch diameter plastic tape and reel, with a base quantity of 3200 units per reel (ordering code suffix /5B). The tape conforms to EIA-481 standards, and the device is packed per J-STD-020 MSL Level 1 requirements, allowing direct placement without baking.
