Product details
Overview
P6SMB510AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 510 V standoff voltage (VWM), 698 V clamping voltage (VC) at 0.86 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects MOSFETs, ICs, and sensor signal lines in industrial power supplies and automotive ECUs against inductive switching transients.
For engineers reviewing the P6SMB510AHE3_A/I datasheet, P6SMB510AHE3_A/I pinout, P6SMB510AHE3_A/I application, or P6SMB510AHE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (via HE3 suffix), MSL Level 1 moisture sensitivity, and 150 °C maximum junction temperature for under-hood automotive environments.
Technical Context
This TVS diode operates as a clamping device that enters avalanche breakdown when reverse voltage exceeds its 510 V stand-off rating, limiting transient energy to safe levels for downstream circuitry. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns), while low incremental surge resistance minimizes voltage overshoot during high-current surges.
The device is designed for automated SMT placement on PCBs with 5.0 mm × 5.0 mm copper pads per terminal, and its thermal resistance (RθJA = 100 °C/W) supports operation up to 150 °C junction temperature without forced cooling-critical for compact, sealed automotive modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ510A | Same VWM/VC ratings but 400 W PPPM; SMA package (smaller footprint, higher RθJA) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a compliance | Select only if space-constrained and surge energy is ≤400 W |
| 1.5KE510A | Through-hole DO-201 package; identical electrical specs but no AEC-Q101 qualification | Not approved for automotive production; requires manual assembly and larger board area | Use only in non-automotive industrial prototypes or legacy designs |
Compared with SMAJ510A and 1.5KE510A, P6SMB510AHE3_A/I delivers automotive-grade reliability in a surface-mount package with verified 600 W surge capacity-making it the sole option meeting both AEC-Q101 and high-power transient requirements in modern 48 V systems.

FAQ
What is the clamping voltage of P6SMB510AHE3_A/I at its rated peak pulse current?
The P6SMB510AHE3_A/I has a maximum clamping voltage (VC) of 698 V when subjected to its specified peak pulse current (IPPM) of 0.86 A using 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. The P6SMB510AHE3_A/I maintains this clamping performance across its full operating temperature range.
Is P6SMB510AHE3_A/I qualified for automotive applications?
Yes, P6SMB510AHE3_A/I is AEC-Q101 qualified, as confirmed by the "HE3" suffix in its ordering code and documented in Vishay's official datasheet. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and surge robustness required for automotive electronic control units. The P6SMB510AHE3_A/I is explicitly designated for use in engine management, ADAS, and body electronics where reliability under thermal and electrical stress is critical.
What does the "_A/I" suffix mean in P6SMB510AHE3_A/I?
The "_A/I" suffix in P6SMB510AHE3_A/I indicates packaging configuration: "A" denotes the revision code (Revision A per Vishay's documentation), and "I" specifies 13-inch diameter plastic tape and reel delivery with 3200 units per reel. This format complies with EIA-481 standards and supports high-volume automated SMT assembly. The P6SMB510AHE3_A/I is RoHS-compliant and halogen-free per Vishay's material categorization guidelines.
Can P6SMB510AHE3_A/I be used in bidirectional configurations?
No, P6SMB510AHE3_A/I is a unidirectional TVS diode, as indicated by the "A" (not "CA") suffix in its part number and confirmed by its cathode band marking. Bidirectional variants in the P6SMB series use the "CA" suffix (e.g., P6SMB510CA). Using P6SMB510AHE3_A/I in bidirectional applications would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit. Always verify polarity alignment before integrating P6SMB510AHE3_A/I into the design.
What is the maximum junction temperature rating for P6SMB510AHE3_A/I?
The P6SMB510AHE3_A/I has a maximum junction temperature (TJ max) rating of +150 °C, as specified in Vishay's datasheet under "Maximum Ratings." This allows reliable operation in high-temperature environments such as engine compartments or enclosed industrial enclosures without thermal derating. The device's thermal resistance (RθJA = 100 °C/W) assumes mounting on 5.0 mm × 5.0 mm copper pads-exceeding this limit may reduce effective TJ margin. The P6SMB510AHE3_A/I sustains full electrical performance up to this temperature threshold.
