Product details
Overview
P6SMB7.5AHM3_B/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 7.13 V minimum breakdown voltage (VBR), 6.40 V standoff voltage (VWM), 11.3 V maximum clamping voltage (VC) at 53.1 A peak pulse current, and 600 W peak pulse power capability with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the P6SMB7.5AHM3_B/H datasheet, P6SMB7.5AHM3_B/H pinout, P6SMB7.5AHM3_B/H application, or P6SMB7.5AHM3_B/H equivalent, this AEC-Q101 qualified, halogen-free, RoHS-compliant TVS offers verified clamping performance, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability board-level ESD and surge protection design validation.
Technical Context
The P6SMB7.5AHM3_B/H operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 7.13–7.88 V breakdown range at 10 mA test current. Its glass-passivated junction ensures stable VBR tolerance and fast response (<1 ns) to transient events such as inductive switching spikes or ESD.
Thermally, it sustains 150 °C maximum junction temperature with 100 °C/W junction-to-ambient thermal resistance (RθJA) on standard 0.2" × 0.2" copper pads. Its 100 A IFSM rating supports robust handling of 8.3 ms half-sine surge currents - essential for automotive load-dump immunity compliance.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A | Same VWM/VBR/VC specs but SMA package (smaller footprint, higher RθJA = 140 °C/W); lower 400 W PPPM rating. | Limited to lower-energy transients; unsuitable for automotive load-dump where 600 W is required. | Select only if board space is constrained and surge energy remains below 400 W. |
| 1.5SMC7.5A | Same electrical specs but SMC (DO-214AB) package; larger footprint, lower RθJA = 70 °C/W; identical 600 W PPPM. | Better thermal performance for high-duty-cycle surge environments; requires more PCB area. | Prefer when thermal management is critical and layout allows SMC's 0.275" × 0.195" outline. |
Compared with SMAJ7.5A and 1.5SMC7.5A, the P6SMB7.5AHM3_B/H delivers optimal balance of 600 W surge capacity, SMB footprint compatibility, AEC-Q101 qualification, and halogen-free compliance - making it the preferred choice for space-constrained, automotive-grade 12 V rail protection.

FAQ
What is the clamping voltage of the P6SMB7.5AHM3_B/H under maximum surge conditions?
The P6SMB7.5AHM3_B/H has a maximum clamping voltage (VC) of 11.3 V at 53.1 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees that protected circuits will not experience voltages exceeding 11.3 V during a 600 W transient event - a key parameter for ensuring compatibility with 5 V and 12 V logic and power rails in the P6SMB7.5AHM3_B/H application space.
Is the P6SMB7.5AHM3_B/H suitable for automotive applications?
Yes, the P6SMB7.5AHM3_B/H is AEC-Q101 qualified (denoted by the "HM3_B" suffix), halogen-free, and RoHS-compliant - meeting stringent automotive reliability requirements. Its 150 °C maximum junction temperature, 100 A IFSM rating, and validated 600 W surge capability make it appropriate for engine control units, body electronics, and infotainment systems where the P6SMB7.5AHM3_B/H serves as primary transient suppression on 12 V supply rails.
What does the "_B/H" suffix mean in P6SMB7.5AHM3_B/H?
The "_B" indicates AEC-Q101 qualification for the P6SMB7.5AHM3_B/H series (covering 6.8 V to 220 V unidirectional/bidirectional variants), while "/H" specifies packaging in 7" diameter plastic tape and reel with 750 units per reel. This ordering code ensures traceable, automotive-grade logistics and matches Vishay's standard delivery format for high-volume production use of the P6SMB7.5AHM3_B/H.
How does the P6SMB7.5AHM3_B/H compare to bidirectional TVS diodes?
The P6SMB7.5AHM3_B/H is unidirectional and intended for DC line protection where polarity is fixed - e.g., +12 V rail to ground. Unlike bidirectional variants (e.g., P6SMB7.5CA), it blocks forward current above ~1.2 V and clamps only in reverse. This makes the P6SMB7.5AHM3_B/H ideal for asymmetric voltage rails, whereas bidirectional types suit AC-coupled or floating signal lines where polarity reversal occurs.
What is the thermal resistance of the P6SMB7.5AHM3_B/H, and how does it affect layout?
The P6SMB7.5AHM3_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. To maintain safe operation under repetitive surges, PCB layout must provide adequate copper area and avoid excessive trace length - especially critical in automotive applications where ambient temperatures exceed 85 °C and the P6SMB7.5AHM3_B/H must sustain repeated 600 W pulses without exceeding 150 °C TJ.
