Product details
Overview
P6SMB150AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, rated for 150 V standoff voltage (VWM), 158 V minimum breakdown voltage (VBR), and 207 V maximum clamping voltage (VC) at 2.9 A peak pulse current (IPPM), designed to protect MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in industrial and automotive electronics.
For engineers reviewing the P6SMB150AHM3/H datasheet, P6SMB150AHM3/H pinout, P6SMB150AHM3/H application, or P6SMB150AHM3/H equivalent, this device delivers verified 600 W peak pulse power (10/1000 μs), AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, and MSL Level 1 moisture sensitivity - critical for high-reliability board-level ESD and surge protection design.
Technical Context
The P6SMB150AHM3/H operates as a unidirectional avalanche diode with glass-passivated junction, exhibiting fast response time (<1 ns) and low incremental surge resistance to clamp transient overvoltages before downstream components are damaged. Its thermal resistance (RθJA = 100 °C/W) and junction temperature limit (TJ max = 150 °C) define safe operating margins under repetitive surge conditions.
Designed for automated SMT placement, it uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets UL 94 V-0 flammability rating. The cathode band identifies polarity, and its SMB package footprint (0.205" × 0.130") supports standard 5.0 mm × 5.0 mm copper pad layouts per JEDEC DO-214AA standards.

FAQ
What is the clamping voltage of P6SMB150AHM3/H at its rated peak pulse current?
The P6SMB150AHM3/H has a maximum clamping voltage (VC) of 207 V at its specified peak pulse current (IPPM) of 2.9 A under the 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and represents the upper voltage limit imposed on the protected circuit during a standardized surge event. The P6SMB150AHM3/H maintains this clamping performance across its qualified operating temperature range.
Is P6SMB150AHM3/H suitable for automotive applications?
Yes, P6SMB150AHM3/H is AEC-Q101 qualified (denoted by the HM3 suffix) and specifically designed for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. It meets stringent requirements for temperature cycling, mechanical shock, and humidity resistance. The P6SMB150AHM3/H also features halogen-free construction and MSL Level 1 rating for robust reflow compatibility in automotive manufacturing.
What does the "HM3" suffix indicate in P6SMB150AHM3/H?
The "HM3" suffix in P6SMB150AHM3/H signifies halogen-free, RoHS-compliant construction with AEC-Q101 qualification. "H" denotes the packaging configuration (7" tape and reel), "M3" confirms halogen-free materials and commercial-grade RoHS compliance, and the "_B" or "_D" revision code (implied in HM3 for this voltage range) indicates AEC-Q101 validation. This distinguishes P6SMB150AHM3/H from non-automotive variants like P6SMB150A-M3/52.
How does the thermal resistance of P6SMB150AHM3/H affect its surge handling capability?
P6SMB150AHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead (RθJL) of 20 °C/W. These values determine how quickly heat dissipates during repetitive surges: lower RθJL enables faster conduction into PCB copper, improving duty-cycle tolerance. For single-pulse events, thermal mass dominates; for repetitive 0.01% duty cycle surges, RθJA governs allowable average power (5.0 W PD rating). The P6SMB150AHM3/H's thermal specs are validated on 5.0 mm × 5.0 mm copper pads per terminal.
Can P6SMB150AHM3/H replace P6SMB150A-E3/52 in an existing design?
P6SMB150AHM3/H is not a direct replacement for P6SMB150A-E3/52 due to differences in qualification and material content: P6SMB150AHM3/H is AEC-Q101 qualified and halogen-free, whereas P6SMB150A-E3/52 is commercial-grade and RoHS-compliant but not halogen-free or automotive-qualified. Electrical parameters (VWM, VBR, VC, PPPM) match exactly, so PCB layout remains unchanged, but system-level automotive certification would require revalidation if substituting P6SMB150AHM3/H into a P6SMB150A-E3/52 design.
