Product details
Overview
SM6T6V8AHE3/52 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 (VC) at 57 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used in automotive sensor protection and industrial I/O interface circuits.
For engineers reviewing the SM6T6V8AHE3/52 datasheet, SM6T6V8AHE3/52 pinout, SM6T6V8AHE3/52 application, or SM6T6V8AHE3/52 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low-inductance SMB package, and compliance with JESD201 Class 2 whisker resistance.
Technical Context
The SM6T6V8AHE3/52 operates as a unidirectional avalanche-clamping device, triggered when reverse voltage exceeds its 6.45–7.14 V breakdown range. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1000 μA at 5.80 V), while the SMB package delivers low thermal resistance (RθJA = 100 °C/W) and meets MSL Level 1 reflow requirements up to 260 °C.
It is rated for non-repetitive 100 A forward surge current (IFSM, 10 ms half-sine) and dissipates 5.0 W continuously at 50 °C ambient on infinite heatsink. Clamping performance is specified under standardized 10/1000 μs waveform conditions per Fig. 1 and Fig. 3 of Vishay Doc. #88385, with derating applied above 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT = 10 mA | 6.45–7.14 V - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 5.80 V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPPM = 57 A (10/1000 μs) | 10.5 V - clamped voltage seen by protected circuit during worst-case surge event |
| PPPM | 600 W - peak transient energy absorption capability under standard 10/1000 μs surge waveform |
| IFSM (10 ms half-sine) | 100 A - surge current handling for short-duration inductive switching events |
| TJ max | 150 °C - maximum allowable junction temperature for sustained operation and reliability |
| Package | SMB (DO-214AA) - surface-mount outline with 0.220" x 0.130" footprint, optimized for automated placement and thermal dissipation |
Pinout & Package

| MSL Level 1 (260 °C peak) | Enables single-reflow assembly without moisture sensitivity concerns or baking requirements |
| RoHS-compliant & halogen-free option available | Meets global environmental regulations; HE3 suffix denotes RoHS + AEC-Q101, no brominated flame retardants |
Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and ground to clamp transients before they reach sensitive input stages. Use Value: Limits voltage to ≤10.5 V during 57 A surges, preventing latch-up or gate oxide damage in downstream ICs. |

IC Role / Device Role / Timing Role: Primary front-end protection element on 24 V DC input channels, mounted directly at connector entry point. Use Value: Absorbs 600 W peak pulse energy without degradation, maintaining functional integrity after repeated 10/1000 μs transients. |
| Consumer Power Adapter Input | Telecom Line Card Surge Protection |
Use Scenario: Secondary-side overvoltage suppression on 5 V/12 V rails in AC/DC adapters subject to lightning-induced surges. IC Role / Device Role / Timing Role: Standoff-rated clamping device parallel to load, activated only during overvoltage events exceeding 5.80 V. Use Value: Delivers <1000 μA leakage at 5.80 V, minimizing standby power loss while enabling fast response to transients. |
Use Scenario: Differential-mode surge protection on Ethernet PHY interfaces or POTS line drivers exposed to telecom-grade surges. IC Role / Device Role / Timing Role: Unidirectional clamp on supply rail feeding line driver ICs, referenced to local ground plane. Use Value: Achieves 10.5 V clamping at 57 A with <20 ns response time, preserving signal integrity during GR-1089-CORE compliant tests. |
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, but lower 600 W rating applies at 1.0 A test current; VBR min/max tighter (6.45–7.14 V identical), yet VC = 11.2 V @ 53.5 A - 0.7 V higher clamping | Not AEC-Q101 qualified; intended for commercial-grade systems only | Select SMAJ6.8A-E3/52 only if automotive qualification is unnecessary and cost is prioritized over clamping margin |
| 1.5SMC6.8A | Higher-power SMC package (same VBR range), 1500 W rating, but larger footprint (0.305" x 0.220") and RθJA = 15 °C/W - requires more board area and better heatsinking | Used where higher surge repetition rate or longer pulse duration (e.g., 8/20 μs) demands greater energy capacity | Choose 1.5SMC6.8A only when 600 W is insufficient and PCB layout allows SMC footprint |
Compared with SMAJ6.8A-E3/52 and 1.5SMC6.8A, SM6T6V8AHE3/52 uniquely combines AEC-Q101 qualification, SMB footprint, and lowest clamping voltage (10.5 V) in its class - making it optimal for space-constrained automotive and industrial edge nodes requiring certified reliability.

FAQ
What is the polarity configuration of SM6T6V8AHE3/52?
The SM6T6V8AHE3/52 is a unidirectional transient voltage suppressor diode, with the cathode identified by a band on the SMB package body. It conducts only when reverse-biased beyond its breakdown voltage, making it suitable for DC rail protection where polarity is fixed. Bidirectional variants use "CA" suffixes (e.g., SM6T6V8CA), which are not interchangeable with SM6T6V8AHE3/52.
Is SM6T6V8AHE3/52 qualified for automotive applications?
Yes, SM6T6V8AHE3/52 carries AEC-Q101 qualification, confirmed in Vishay Document #88385 (Revision 09-Jan-2024). The "HE3" suffix explicitly denotes RoHS-compliant and AEC-Q101 qualified construction, validated for temperature cycling, highly accelerated life testing, and ESD robustness required in automotive ECUs and sensor modules.
What is the maximum clamping voltage of SM6T6V8AHE3/52 under surge conditions?
The SM6T6V8AHE3/52 has a maximum clamping voltage (VC) of 10.5 V when subjected to a 10/1000 μs waveform peak pulse current (IPPM) of 57 A, as specified in Table "ELECTRICAL CHARACTERISTICS" of Vishay Doc. #88385. This value represents the upper limit of voltage imposed on the protected circuit during worst-case transient events.
Does SM6T6V8AHE3/52 require special PCB layout considerations?
Yes - Vishay specifies mounting on minimum 0.2" x 0.2" (5.0 mm x 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power and thermal performance. Trace inductance must be minimized: keep leads short and wide, avoid vias near terminals, and use solid ground planes beneath the SMB footprint to reduce clamping overshoot during fast transients.
How does the "HE3" suffix affect the specifications of SM6T6V8AHE3/52?
The "HE3" suffix on SM6T6V8AHE3/52 indicates RoHS-compliance and full AEC-Q101 qualification - distinct from commercial-grade "E3" or halogen-free "HM3" variants. Electrically and thermally identical to base SM6T6V8A, the HE3 version adds automotive-grade reliability screening, JESD201 Class 2 whisker resistance, and extended temperature validation per AEC stress profiles.
