For engineers reviewing the P6SMB75AHM3_A/H datasheet, P6SMB75AHM3_A/H pinout, P6SMB75AHM3_A/H application, or P6SMB75AHM3_A/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (–65 to +150 °C), and real-world clamping performance data under standardized surge conditions.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, optimized for fast transient suppression in DC power rails and low-speed signal paths. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and low incremental surge resistance, enabling consistent clamping across repetitive 10/1000 μs pulses at 0.01% duty cycle.
The device meets J-STD-020 MSL Level 1 (peak reflow ≤ 260 °C), uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and is halogen-free and RoHS-compliant per Vishay HM3 suffix designation. It is AEC-Q101 qualified for automotive applications, with ordering code suffix _HM3_A/H confirming halogen-free, AEC-Q101-compliant, and 7" tape-and-reel packaging.

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-E3/52 | Same VWM (64.1 V), identical SMB package, but commercial-grade (non-AEC-Q101) and RoHS-compliant E3 suffix (not halogen-free). | Lacks automotive qualification; suitable for industrial/commercial power supplies where AEC-Q101 is not mandated. | Select SMAJ75A-E3/52 if cost sensitivity outweighs automotive compliance and halogen-free requirements. |
| 1.5SMC75A | Higher RθJA (125 °C/W), same VWM/VC, but larger SMC (DO-214AB) package - 2.5 mm wider and 0.5 mm taller than SMB. | Requires PCB layout revision; offers higher thermal mass but reduces board density - used where surge repetition rate exceeds P6SMB75AHM3_A/H derating limits. | Choose 1.5SMC75A only when sustained surge duty cycles demand extra thermal margin and board space permits larger footprint. |
Compared with SMAJ75A-E3/52, P6SMB75AHM3_A/H adds AEC-Q101 qualification and halogen-free construction for automotive deployment; versus 1.5SMC75A, it delivers identical clamping performance in a 25% smaller SMB footprint - critical for space-constrained ADAS camera modules and telematics units.

FAQ
What is the clamping voltage of P6SMB75AHM3_A/H at its rated peak pulse current?
The P6SMB75AHM3_A/H has a maximum clamping voltage (VC) of 103 V at 5.8 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88370 and defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB75AHM3_A/H maintains this clamping performance across its full operating temperature range (–65 to +150 °C) when mounted per recommended pad layout.
Is P6SMB75AHM3_A/H qualified for automotive applications?
Yes, P6SMB75AHM3_A/H is AEC-Q101 qualified, as confirmed by the HM3 suffix and Vishay's ordering information table (Document 88370, page 3). It undergoes stress testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC-Q101 Rev D. The "_A/H" suffix denotes 7" tape-and-reel packaging with AEC-Q101 compliance, making P6SMB75AHM3_A/H suitable for engine control, body electronics, and ADAS power systems.
What does the "HM3" suffix mean in P6SMB75AHM3_A/H?
The "HM3" suffix in P6SMB75AHM3_A/H indicates halogen-free, RoHS-compliant construction meeting IPC-1752A material declaration standards, plus AEC-Q101 qualification. It distinguishes the part from commercial-grade variants (e.g., E3 or M3) and confirms compliance with automotive environmental requirements. The "_A/H" further specifies revision A and 7" tape-and-reel packaging - all documented in Vishay's P6SMB Series datasheet (88370, page 3).
How does P6SMB75AHM3_A/H compare to P6SMB75A in terms of reliability and packaging?
P6SMB75AHM3_A/H differs from generic P6SMB75A by incorporating AEC-Q101 qualification, halogen-free molding compound, and controlled moisture sensitivity (MSL Level 1). While both share identical electrical specs (VWM = 64.1 V, VC = 103 V), only P6SMB75AHM3_A/H carries the HM3 suffix and _A/H packaging code - ensuring traceable, automotive-grade supply chain integrity. P6SMB75AHM3_A/H is not a drop-in replacement for non-HM3 variants in certified automotive designs.
What is the thermal resistance of P6SMB75AHM3_A/H, and how does it affect layout?
P6SMB75AHM3_A/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, as specified in Vishay's thermal characteristics table (page 3, Document 88370). This value requires PCB designers to allocate adequate copper area and avoid thermal bottlenecks - especially in high-ambient environments like automotive cabins - to maintain junction temperature below +150 °C during repetitive surge events.
