Product details
Overview
P6SMB75AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on power and signal lines. It features a 75 V standoff voltage (VWM), 78.8 V maximum breakdown voltage (VBR), 103 V clamping voltage at 5.8 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies and automotive ECUs.
For engineers reviewing the P6SMB75AHE3_B/H datasheet, P6SMB75AHE3_B/H pinout, P6SMB75AHE3_B/H application, or P6SMB75AHE3_B/H equivalent, key selection criteria include its AEC-Q101 qualification, SMB (DO-214AA) package compatibility, unidirectional polarity with cathode band marking, and thermal resistance (RθJA = 100 °C/W) under standard PCB pad layout.
Technical Context
This TVS diode operates as a clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (VBR = 71.3–78.8 V), limiting transient energy to safe levels for downstream components. Its low incremental surge resistance ensures minimal voltage overshoot during fast transients, and its glass-passivated junction provides stable performance across temperature.
The device is rated for repetitive 10/1000 μs pulses at 0.01 % duty cycle, with derating above TA = 25 °C per Fig. 2 of the datasheet. It meets J-STD-020 MSL Level 1 (peak reflow = 260 °C) and supports automated SMT placement due to its low-profile SMB package and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 64.1 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC/AC line operating margin. |
| VBR (Breakdown Voltage) | 71.3–78.8 V at IT = 1 mA - Voltage at which avalanche conduction begins; determines minimum clamping trigger point. |
| VC (Clamping Voltage) | 103 V at IPPM = 5.8 A - Peak voltage seen by protected circuit during 10/1000 μs transient; critical for IC voltage tolerance compliance. |
| PPPM (Peak Pulse Power) | 600 W - Maximum transient energy absorption capability under standardized 10/1000 μs waveform; defines surge robustness class. |
| ID (Max Reverse Leakage) | 1.0 μA at VWM - Low leakage preserves system efficiency and prevents false triggering in high-impedance circuits. |
| TJ max | 150 °C - Maximum junction temperature; sets thermal design limits for PCB copper area and ambient operating range. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient on standard 0.2" × 0.2" copper pads; guides heatsinking requirements. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads. Cathode indicated by a band on the body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference | Connected to lower-potential side (e.g., ground or return path); defines polarity for unidirectional clamping. |
| Cathode | Avalanche conduction terminal | Marked with band; connected to higher-potential line (e.g., VBUS, signal line) to clamp positive transients to ground. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS sensors, supporting long-term reliability under thermal cycling and vibration. |
| 600 W peak pulse power | Handles IEC 61000-4-5 Level 4 surges (4 kV line-to-ground) without degradation when mounted per recommended pad layout. |
| Low clamping ratio (VC/VBR ≈ 1.30) | Minimizes overvoltage stress on protected ICs - e.g., keeps 3.3 V or 5 V logic inputs within safe margins during ESD or load dump events. |
| MSL Level 1 moisture sensitivity | Enables direct placement into reflow ovens without baking; eliminates production delays and moisture-related delamination risk. |
| Glass-passivated junction | Ensures stable VBR and low leakage over time and temperature, critical for mission-critical industrial and automotive deployments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ75A-E3/5B | Same SMB package, 75 V VWM, but lower PPPM (400 W) and higher VC (121 V at 4.9 A). | Not AEC-Q101 qualified; suitable for commercial-grade consumer electronics only. | Select when cost is prioritized over automotive qualification and surge margin. |
| 1.5SMC75A | Higher power (1500 W), larger SMC (DO-214AB) package, same VWM/VC specs, but not AEC-Q101 qualified. | Requires larger PCB footprint and different thermal layout; suited for high-energy industrial AC line protection. | Choose when system-level surge test requirements exceed 600 W and board space allows SMC footprint. |
Compared with SMAJ75A-E3/5B and 1.5SMC75A, P6SMB75AHE3_B/H uniquely delivers AEC-Q101 qualification in the compact SMB form factor with balanced 600 W capability and 103 V clamping - making it optimal for space-constrained automotive and industrial designs requiring certified reliability.

FAQ
What is the clamping voltage of the P6SMB75AHE3_B/H under a 10/1000 μs transient?
The P6SMB75AHE3_B/H has a maximum clamping voltage (VC) of 103 V at a peak pulse current (IPPM) of 5.8 A with a 10/1000 μs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads), and represents the upper voltage limit imposed on protected circuitry during surge events. The P6SMB75AHE3_B/H maintains this clamping performance consistently across its qualified operating temperature range.
Is the P6SMB75AHE3_B/H AEC-Q101 qualified?
Yes, the P6SMB75AHE3_B/H is AEC-Q101 qualified, as confirmed by the "HE3" base suffix and "_B" revision code in its ordering designation. This qualification covers stress tests including high-temperature operating life, temperature cycling, and mechanical shock - validating its suitability for automotive applications such as body control modules and ADAS sensor power supplies. The P6SMB75AHE3_B/H is not a commercial-grade variant.
What does the "_B/H" suffix mean in P6SMB75AHE3_B/H?
The "_B" denotes AEC-Q101 qualification for the P6SMB75AHE3_B/H within the 6.8 V to 220 V unidirectional/bidirectional voltage range, while "/H" specifies packaging in 7" diameter plastic tape and reel with a 750-unit quantity per reel. This suffix combination confirms both automotive reliability compliance and logistics-ready SMT handling - distinct from non-qualified "E3" or halogen-free "HM3" variants.
Can the P6SMB75AHE3_B/H be used in bidirectional configurations?
No, the P6SMB75AHE3_B/H is a unidirectional TVS diode, as indicated by its "A" suffix and cathode band marking. Bidirectional variants in the same series use the "CA" suffix (e.g., P6SMB75CA). Using the P6SMB75AHE3_B/H in bidirectional applications would result in forward conduction during negative transients, potentially damaging the device or failing to suppress. Always match polarity to circuit topology.
What is the thermal resistance of the P6SMB75AHE3_B/H, and how does it affect PCB layout?
The P6SMB75AHE3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes standard FR-4 PCB construction; reducing RθJA requires increasing copper area or adding internal planes. For sustained power dissipation near its 5.0 W rating, designers must verify junction temperature stays ≤150 °C using this RθJA and actual ambient conditions.
