Product details
Overview
P6SMB75AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 71.3 V minimum breakdown voltage (VBR), 64.1 V standoff voltage (VWM), 103 V maximum clamping voltage at 5.8 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6SMB75AHM3/H datasheet, P6SMB75AHM3/H pinout, P6SMB75AHM3/H application, or P6SMB75AHM3/H equivalent, key selection criteria include its AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, low incremental surge resistance, and suitability for automotive-grade ESD/surge protection where clamping performance and thermal reliability under repetitive transients are critical.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, optimized for fast response (<1 ns) to transient overvoltages induced by inductive switching or lightning surges. Its glass-passivated junction ensures stable leakage and long-term reliability under thermal cycling.
The device delivers 600 W peak pulse power handling per 10/1000 µs waveform at TA = 25 °C, derated linearly above 25 °C with RθJA = 100 °C/W. It supports 100 A non-repetitive forward surge current (IFSM) and operates across -65 °C to +150 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff) | 64.1 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown, min) | 71.3 V - Minimum voltage at which device enters avalanche conduction at 1 mA test current; ensures consistent turn-on behavior |
| VC (Clamping, max) | 103 V at 5.8 A IPPM - Peak voltage seen by protected circuit during worst-case 10/1000 µs surge; determines stress on downstream components |
| PPPM | 600 W - Sustained transient energy absorption capability without failure; validated per JEDEC standards |
| IPPM | 5.8 A - Peak surge current supported at VC = 103 V; directly correlates with PCB trace robustness and layout requirements |
| TJ max | +150 °C - Maximum junction temperature; enables operation in high-ambient environments like engine control units or industrial drives |
| Package | SMB (DO-214AA) - Surface-mount outline with 0.205" × 0.220" footprint; compatible with automated pick-and-place and reflow soldering |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads, MSL Level 1 compliant (peak reflow ≤ 260 °C), UL 94 V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Anode-side connection point in unidirectional configuration | Connected to protected line; reverse-biased during normal operation; conducts during overvoltage to shunt current to ground |
| Anode | Reference/ground connection point | Typically tied to system ground or low-impedance return path; completes clamping loop during transient events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including powertrain and body electronics; supports extended temperature and lifetime reliability requirements |
| Halogen-free & RoHS-compliant | Meets environmental regulations for green manufacturing; HM3 suffix confirms halogen-free molding compound and terminations |
| 600 W peak pulse power | Enables protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) without derating in standard PCB layouts |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on protected ICs; improves system-level immunity without requiring oversized voltage margins |
| Fast response time (< 1 ns) | Clamps transients before sensitive logic or analog circuits experience damage; critical for protecting high-speed interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ75A | Same VWM (64.1 V), lower PPPM (400 W), SMA package (smaller footprint, higher RθJA) | Limited to lower-energy transients; not AEC-Q101 qualified | Select when space-constrained and automotive qualification is unnecessary |
| 1.5SMC75A | Same VWM/VC, higher PPPM (1500 W), larger SMC package (DO-214AB), higher IPPM (16.3 A) | Better suited for high-energy industrial surges but requires larger PCB area | Choose when legacy board redesign allows larger footprint and higher surge margin is required |
Compared with SMAJ75A and 1.5SMC75A, P6SMB75AHM3/H offers balanced surge capability (600 W), AEC-Q101 qualification, and SMB footprint - making it optimal for new automotive and industrial designs needing verified reliability without sacrificing board space.

FAQ
What is the clamping voltage of P6SMB75AHM3/H at its rated peak pulse current?
The P6SMB75AHM3/H has a maximum clamping voltage (VC) of 103 V at 5.8 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuits during surge events. The clamping performance is guaranteed across the full operating temperature range and remains stable over lifetime due to glass-passivated junction construction.
Is P6SMB75AHM3/H suitable for automotive applications?
Yes, P6SMB75AHM3/H is AEC-Q101 qualified, as confirmed by the "HM3" suffix indicating halogen-free, RoHS-compliant, and automotive-grade construction. It meets stringent requirements for temperature cycling, humidity resistance, and surge endurance - making it appropriate for use in engine control units, body electronics, and ADAS power domains where reliability under vibration and thermal stress is essential.
What does the "H" in P6SMB75AHM3/H signify?
The "H" in P6SMB75AHM3/H denotes the packaging configuration: 7-inch diameter plastic tape and reel, with 750 units per reel. This delivery format is optimized for high-volume SMT assembly lines using standard feeder equipment. The "HM3" portion confirms halogen-free materials and RoHS compliance, while the "/H" suffix specifically identifies the reel size and quantity - distinct from "/I" (13-inch reel, 3200 units).
How does P6SMB75AHM3/H compare to bidirectional TVS diodes like P6SMB75CA?
P6SMB75AHM3/H is unidirectional and intended for DC line protection with defined polarity (cathode band), whereas P6SMB75CA is bidirectional and symmetrical - suitable for AC or floating signal lines. The unidirectional version offers lower leakage at VWM and slightly tighter VBR tolerance, while the bidirectional variant provides equal clamping in both directions but higher reverse leakage. Selection depends on circuit topology and grounding scheme.
What is the thermal resistance of P6SMB75AHM3/H, and how does it affect layout design?
P6SMB75AHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads per terminal. This value guides PCB layout: increasing copper area or adding thermal vias reduces effective RθJA, improving surge repetition capability. For high-duty-cycle applications, designers should verify junction temperature rise using IPPM derating curves from the datasheet to avoid thermal runaway.
