Product details
Overview
P6SMB510AHM3_D/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for high-energy surge protection on power and signal lines. It features a 485 V to 535 V breakdown voltage (VBR), 434 V stand-off voltage (VWM), 600 W peak pulse power rating (10/1000 μs), 0.86 A peak pulse current (IPPM), and clamps transients to ≤698 V at rated surge. It is used in automotive-grade power rail protection where AEC-Q101 qualification and halogen-free RoHS compliance are required.
For engineers reviewing the P6SMB510AHM3_D/H datasheet, P6SMB510AHM3_D/H pinout, P6SMB510AHM3_D/H application, or P6SMB510AHM3_D/H equivalent, key selection criteria include its 434 V working voltage, 698 V clamping level under 0.86 A surge, SMB (DO-214AA) package compatibility with automated SMT assembly, AEC-Q101 qualification status, and suitability for high-voltage DC bus protection in EV charging infrastructure and industrial power supplies.
Technical Context
This TVS diode operates as a unidirectional clamping device, conducting only during reverse-biased overvoltage events while remaining high-impedance under normal operating conditions up to 434 V. Its glass-passivated junction ensures stable leakage performance and robust surge endurance.
The device delivers 600 W peak pulse power handling per the standardized 10/1000 μs waveform, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling reliable operation in compact PCB layouts with minimal copper pad area (0.2" × 0.2").

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ510A-E3/5B | Same 510 V nominal breakdown but lower 400 W PPPM, SMA package (smaller footprint, higher RθJA) | Not AEC-Q101 qualified; limited to commercial-grade industrial use | Select when board space is constrained and automotive qualification is unnecessary |
| 1.5SMC510AHE3_A | Same 510 V rating, 600 W rating, but SMC (DO-214AB) package - larger footprint, lower RθJA (75 °C/W) | AEC-Q101 qualified, but not halogen-free; requires larger PCB pad area | Select when thermal performance is critical and halogen-free compliance is secondary |
Compared with P6SMB510AHM3_D/H, SMAJ510A-E3/5B offers smaller size but reduced surge capacity and no automotive qualification, while 1.5SMC510AHE3_A provides better thermal dissipation in a larger package but lacks halogen-free certification - making P6SMB510AHM3_D/H optimal for space-constrained, AEC-Q101–required, environmentally compliant high-voltage protection.

FAQ
What is the maximum clamping voltage of the P6SMB510AHM3_D/H under rated surge conditions?
The P6SMB510AHM3_D/H clamps to a maximum of 698 V when subjected to its rated peak pulse current of 0.86 A using the standard 10/1000 μs waveform. This value is measured at the device terminals under defined test conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads) and defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB510AHM3_D/H maintains this clamping performance consistently across its qualified temperature range.
Is the P6SMB510AHM3_D/H AEC-Q101 qualified and what does the 'HM3' suffix indicate?
Yes, the P6SMB510AHM3_D/H is AEC-Q101 qualified, as confirmed by Vishay's ordering information table specifying '_D' suffix for AEC-Q101 devices in the 250–540 V range and '_HM3' denoting halogen-free, RoHS-compliant, and AEC-Q101–qualified construction. The HM3 suffix replaces older M3 commercial-grade variants and ensures compliance with automotive reliability stress tests including temperature cycling, humidity bias, and mechanical shock - critical for use in EV power electronics.
What is the standoff voltage (VWM) of the P6SMB510AHM3_D/H and why is it important for system design?
The P6SMB510AHM3_D/H has a standoff voltage (VWM) of 434 V, representing the maximum continuous reverse voltage it can block without exceeding 1 μA leakage current. This parameter is essential for ensuring the device remains non-conductive during normal operation - for example, on a 400 V DC bus - while still triggering reliably during overvoltage events. Selecting a VWM ≥10–15% below system maximum operating voltage prevents premature conduction and thermal runaway in the P6SMB510AHM3_D/H.
Can the P6SMB510AHM3_D/H be used in bidirectional configurations?
No, the P6SMB510AHM3_D/H is a unidirectional TVS diode, as indicated by its part number ending in 'A' (not 'CA') and its specified polarity: cathode band marking and forward voltage characteristics. Bidirectional operation requires CA-suffix variants like P6SMB510CA, which have symmetrical breakdown in both directions. Using the P6SMB510AHM3_D/H in bidirectional circuits would result in unintended conduction during positive half-cycles and failure to protect against negative transients.
What is the thermal resistance profile of the P6SMB510AHM3_D/H and how does it affect PCB layout?
The P6SMB510AHM3_D/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W. These values assume mounting on minimum recommended 0.2" × 0.2" copper pads per terminal. To maintain safe junction temperatures under repeated surges, designers must provide adequate copper area and consider airflow - especially since the P6SMB510AHM3_D/H operates up to +150 °C. Reducing pad size increases RθJA, risking thermal overstress during high-duty-cycle transients.
