Overview
P6SMB75AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 64.1 V standoff voltage (VWM), 71.3–78.8 V breakdown voltage (VBR) at 1 mA, 103 V clamping voltage (VC) at 5.8 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O modules.
For engineers reviewing the P6SMB75AHM3_A/I datasheet, P6SMB75AHM3_A/I pinout, P6SMB75AHM3_A/I application, or P6SMB75AHM3_A/I equivalent, key selection criteria include its AEC-Q101 qualification, halogen-free RoHS-compliant construction (HM3 suffix), MSL Level 1 moisture sensitivity, and verified clamping performance under repetitive surge conditions per JESD22-B102 whisker testing.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging a glass-passivated silicon junction to deliver fast response (<1 ps) and low incremental surge resistance. Its design targets transient suppression on 48 V and 60 V DC systems where sustained reverse leakage must remain ≤1.0 µA at VWM.
The device is rated for 150 °C maximum junction temperature and exhibits a +0.105 %/°C temperature coefficient of VBR, enabling stable clamping across automotive under-hood thermal profiles. Mounting on 5.0 mm × 5.0 mm copper pads ensures thermal derating compliance up to 100 °C ambient per Fig. 2.

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-E3/5B | Same VWM (64.1 V), identical SMB package, but commercial-grade (E3), not AEC-Q101 qualified or halogen-free. | Lacks automotive qualification and whisker resistance; suitable only for non-automotive industrial or consumer use. | Select when AEC-Q101 and halogen-free requirements are absent and cost optimization is prioritized. |
| 1.5SMC75A-Q | Same electrical specs (VWM, VBR, VC), SMC (DO-214AB) package - 2.6 mm wider body, higher thermal mass, but incompatible footprint. | Requires PCB layout change; better suited for higher-power derating needs (>100 °C ambient) due to lower RθJA. | Choose only if thermal performance exceeds SMB limits and board space allows larger SMC footprint. |
Compared with SMAJ75A-E3/5B, P6SMB75AHM3_A/I adds AEC-Q101 validation and halogen-free compliance for automotive deployment; versus 1.5SMC75A-Q, it offers drop-in SMB compatibility but trades off thermal margin for compactness - critical for space-constrained ECU modules.

FAQ
What is the maximum clamping voltage of P6SMB75AHM3_A/I under a 10/1000 µs surge?
The maximum clamping voltage (VC) of P6SMB75AHM3_A/I is 103 V at 5.8 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value is measured per standard test conditions in the Vishay datasheet (Document Number: 88370, Rev. 09-Jan-2024) and defines the upper voltage limit imposed on protected circuitry during surge events. P6SMB75AHM3_A/I maintains this clamping performance across its specified operating temperature range.
Is P6SMB75AHM3_A/I qualified for automotive applications?
Yes, P6SMB75AHM3_A/I is AEC-Q101 qualified, as indicated by the "HM3" suffix and confirmed in the Vishay P6SMB Series datasheet. It meets all required stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT). The "HM3" designation also confirms halogen-free and RoHS-compliant construction, satisfying Tier 1 automotive material requirements. P6SMB75AHM3_A/I is intended for use in engine control units, body electronics, and ADAS sensor modules.
What does the "_A/I" suffix in P6SMB75AHM3_A/I signify?
The "_A/I" suffix in P6SMB75AHM3_A/I denotes packaging configuration: "A" indicates the base part is the unidirectional P6SMB75A variant; "I" specifies 13-inch diameter plastic tape and reel delivery (3200 units per reel), per Vishay's ordering information table. The "HM3" portion confirms halogen-free, RoHS-compliant, and AEC-Q101-qualified construction. P6SMB75AHM3_A/I is therefore a fully qualified automotive-grade TVS diode supplied in high-volume reel format.
Can P6SMB75AHM3_A/I be used in bidirectional configurations?
No, P6SMB75AHM3_A/I is a unidirectional TVS diode, as confirmed by its part number structure (ending in "A", not "CA") and electrical specifications - including forward surge current rating (IFSM = 100 A) and absence of symmetrical VBR min/max values for both polarities. Bidirectional variants use the "CA" suffix (e.g., P6SMB75CA). Using P6SMB75AHM3_A/I in bidirectional applications would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit.
What is the thermal resistance of P6SMB75AHM3_A/I, and how does it affect layout?
P6SMB75AHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 5.0 mm × 5.0 mm copper pads per terminal, as specified in the Vishay datasheet. This value assumes no additional heatsinking. To maintain TJ ≤ 150 °C under sustained 5.0 W power dissipation (PD), PCB layout must provide adequate copper area and avoid thermal bottlenecks. P6SMB75AHM3_A/I requires adherence to the documented pad layout to ensure reliable operation in automotive and industrial environments.
