Product details
Overview
P6SMB6.8AHM3_A/I from Vishay General Semiconductor is a unidirectional 600 W surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, with 6.45 V minimum and 7.14 V maximum breakdown voltage at 10 mA test current, 5.80 V stand-off voltage, and 10.5 V clamping voltage at 57.1 A peak pulse current. It protects sensitive ICs and MOSFETs against inductive switching transients and ESD in automotive and industrial power rails.
For engineers reviewing the P6SMB6.8AHM3_A/I datasheet, P6SMB6.8AHM3_A/I pinout, P6SMB6.8AHM3_A/I application, or P6SMB6.8AHM3_A/I equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance data, clamping performance under 10/1000 µs surge, and real-world protection use cases - all confirmed from Vishay's official P6SMB series documentation dated 09-Jan-2024.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, optimized for fast transient suppression on DC power lines and signal paths. Its glass-passivated junction ensures stable breakdown behavior, low incremental surge resistance, and repeatable clamping at 10.5 V under 57.1 A 10/1000 µs pulses.
Rated for 150 °C maximum junction temperature and MSL Level 1 moisture sensitivity, it supports lead-free reflow up to 260 °C peak. The halogen-free, RoHS-compliant HM3 suffix confirms AEC-Q101 qualification and JESD201 Class 2 whisker resistance - critical for automotive ECUs and industrial controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 6.45–7.14 V at 10 mA - defines precise conduction onset for overvoltage triggering |
| Stand-off Voltage VWM | 5.80 V - maximum continuous reverse voltage before leakage exceeds 1000 µA |
| Clamping Voltage VC | 10.5 V at 57.1 A (10/1000 µs) - limits downstream voltage during surge events |
| Peak Pulse Power PPPM | 600 W - sustains high-energy transients without failure at rated duty cycle (0.01 %) |
| Junction-to-Ambient RθJA | 100 °C/W - determines thermal derating on standard 0.2" × 0.2" copper pads |
| Operating Temperature | -65 to +150 °C - enables deployment in under-hood automotive and wide-temperature industrial environments |
| AEC-Q101 Qualified | Yes (HM3 suffix) - validated for automotive electronics per stress-test requirements |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD22-B102. Cathode identified by black band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to protected circuit ground or low-side rail | Provides reference node for clamping action; must be routed with low-inductance path to ground plane |
| Cathode | Current exit point in forward bias; connected to protected line (e.g., 5 V supply rail) | Defines polarity-sensitive placement - reverse connection disables protection function |
Key Features

Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Card |
|---|---|
Use Scenario: Protects microcontroller I/O pins and CAN transceiver power rails from load-dump spikes during battery disconnect/reconnect events. IC Role / Device Role / Timing Role: Unidirectional TVS placed between 5 V supply and chassis ground to clamp transients before they reach LDOs and MCU VDD pins. Use Value: Prevents latch-up and permanent damage to 5 V tolerant peripherals during 12 V system surges exceeding 200 V for 400 ms. |
Use Scenario: Shields 24 V digital input optocoupler front-end from field-wiring induced surges caused by relay coil de-energization. IC Role / Device Role / Timing Role: Standoff-rated TVS on 24 V input line, conducting only when transient exceeds 5.8 V, minimizing standby leakage. Use Value: Maintains <1 µA leakage at 24 V nominal while clamping 1 kV/1 Ω ring wave to ≤30 V at the optocoupler anode. |
| Consumer Appliance Motor Drive Board | Telecom Power Supply Front-End |
Use Scenario: Guards gate driver ICs and bootstrap capacitors against voltage reversal and inductive kickback from BLDC motor phase switches. IC Role / Device Role / Timing Role: Fast-response unidirectional suppressor mounted directly at half-bridge high-side FET source node. Use Value: Limits negative undershoot to >−0.7 V and clamps positive overshoot to <10.5 V, preserving gate oxide integrity. |
Use Scenario: Safeguards AC-DC controller ICs and bulk capacitor charging circuits from lightning-induced surges on primary-side rectifier outputs. IC Role / Device Role / Timing Role: Secondary-stage TVS on 300–400 V DC bus, triggered only during rare overvoltage events beyond normal regulation range. Use Value: Absorbs 600 W surge energy without thermal runaway, enabling compliance with IEC 61000-4-5 Level 4 (4 kV line-earth). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.8A-Q | Same 6.8 V nominal breakdown, but SMA package (DO-214AC); lower PPPM (400 W); non-AEC-Q101 | Limited to commercial-grade consumer/industrial use; not qualified for automotive under-hood deployment | Select when cost sensitivity outweighs automotive qualification and 600 W surge margin is unnecessary |
| 1.5SMC6.8A | Same electrical specs, but larger SMC (DO-214AB) package; higher thermal mass; identical AEC-Q101 HM3 option available | Better thermal dissipation in high-ambient environments (>105 °C), but requires 30 % more PCB area | Choose when board space permits and junction temperature rise must stay <25 °C under repetitive surge conditions |
Compared with SMAJ6.8A-Q and 1.5SMC6.8A, the P6SMB6.8AHM3_A/I uniquely balances AEC-Q101 compliance, 600 W surge capability, and compact SMB footprint - making it optimal for space-constrained automotive modules where both reliability and size matter.

FAQ
What is the clamping voltage of P6SMB6.8AHM3_A/I at its rated peak pulse current?
The P6SMB6.8AHM3_A/I has a maximum clamping voltage (VC) of 10.5 V at 57.1 A peak pulse current under the standardized 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88370 and ensures downstream 5 V logic remains within safe operating limits during surge events. The P6SMB6.8AHM3_A/I maintains this clamping performance across its full operating temperature range.
Is P6SMB6.8AHM3_A/I qualified for automotive applications?
Yes, the P6SMB6.8AHM3_A/I carries the HM3 suffix, confirming it is halogen-free, RoHS-compliant, and AEC-Q101 qualified per Vishay's ordering information table. This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - making the P6SMB6.8AHM3_A/I suitable for automotive body electronics, infotainment power supplies, and ADAS sensor interfaces.
What does the "_A/I" suffix mean in P6SMB6.8AHM3_A/I?
The "_A/I" suffix in P6SMB6.8AHM3_A/I indicates packaging configuration: "A" denotes the revision code (per Vishay's note on page 3), and "I" specifies 13-inch diameter plastic tape and reel with 3200 units per reel. This matches the ordering example P6SMB6.8AHM3_B/I in the same datasheet, confirming full compatibility with high-speed automated pick-and-place equipment.
How does P6SMB6.8AHM3_A/I differ from the non-HM3 version like P6SMB6.8A-E3?
The P6SMB6.8AHM3_A/I differs from P6SMB6.8A-E3 in three key ways: it is halogen-free (vs. standard RoHS), AEC-Q101 qualified (vs. commercial grade only), and supplied in 13" tape-and-reel (vs. 7" for -E3/52). Electrically, both share identical VBR, VWM, and VC specs, but the P6SMB6.8AHM3_A/I adds automotive-grade reliability assurance and material compliance required by Tier 1 suppliers.
What is the maximum reverse leakage current for P6SMB6.8AHM3_A/I at its stand-off voltage?
At its 5.80 V stand-off voltage (VWM), the P6SMB6.8AHM3_A/I exhibits a maximum reverse leakage current (ID) of 1000 µA, as specified in the Electrical Characteristics table on page 2 of Vishay document 88370. This low leakage ensures minimal power loss in always-on automotive modules and preserves battery life in sleep-mode systems using the P6SMB6.8AHM3_A/I.
