Product details
Overview
P6SMB510AHM3_A/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 510 V standoff voltage (VWM), 535 V minimum breakdown voltage (VBR), 600 W peak pulse power (10/1000 μs), 0.86 A maximum peak pulse current (IPPM), and clamps transients to ≤698 V at rated surge. It is used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies and automotive ECUs.
For engineers reviewing the P6SMB510AHM3_A/H datasheet, P6SMB510AHM3_A/H pinout, P6SMB510AHM3_A/H application, or P6SMB510AHM3_A/H equivalent, key selection criteria include its 510 V VWM rating, unidirectional polarity, SMB (DO-214AA) package compatibility with automated SMT assembly, AEC-Q101 qualification status, and thermal resistance (RθJA = 100 °C/W) under standard pad layout.
Technical Context
This TVS diode operates as a clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (VBR = 485–535 V). Its low incremental surge resistance ensures stable clamping performance during repetitive 10/1000 μs transients up to 600 W, with derating above 25 °C per Fig. 2 of the datasheet.
The device uses a glass-passivated junction for reliability and meets MSL Level 1 per J-STD-020 (peak reflow temperature 260 °C). Its unidirectional configuration features a cathode band marking, and it is halogen-free, RoHS-compliant, and qualified to AEC-Q101 for automotive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 434 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working margin. |
| VBR (Breakdown Voltage) | 485–535 V at IT = 1.0 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | ≤698 V at IPPM - Peak voltage seen by protected circuit during 600 W transient; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 600 W (10/1000 μs waveform) - Energy-handling capacity for standardized surge testing; supports IEC 61000-4-5 compliance. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient on 0.2" × 0.2" copper pads; guides PCB thermal design for sustained operation. |
| TJ max. | +150 °C - Maximum allowable junction temperature; enables use in under-hood automotive and industrial environments. |
| AEC-Q101 Qualified | Yes (HM3 suffix) - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by band marking on unidirectional devices.

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 VWM/VBR/VC specs but SMA package (higher RθJA = 150 °C/W); non-AEC-Q101; RoHS-compliant only. | Limited to commercial-grade industrial or telecom use; not suitable for automotive under-hood deployment. | Select when cost sensitivity outweighs thermal or automotive qualification requirements. |
| 1.5KE510A | Through-hole DO-201 package; identical electrical specs but larger footprint and manual assembly required. | Used where board space is unconstrained and wave soldering is preferred; lacks MSL Level 1 reflow compatibility. | Choose for legacy designs or prototyping where SMT infrastructure is unavailable. |
Compared with SMAJ510A-E3/5B and 1.5KE510A, P6SMB510AHM3_A/H uniquely combines AEC-Q101 qualification, SMB package size, and 100 °C/W thermal resistance-making it optimal for space-constrained, high-reliability automotive and industrial SMT production.

FAQ
What is the clamping voltage of P6SMB510AHM3_A/H at its rated peak pulse current?
The P6SMB510AHM3_A/H has a maximum clamping voltage (VC) of 698 V when subjected to its rated peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured at 0.86 A and defines the upper voltage limit imposed on protected circuitry during surge events. The clamping performance is guaranteed across the full operating temperature range and is validated per the manufacturer's test conditions using specified mounting pad layout.
Is P6SMB510AHM3_A/H suitable for automotive applications?
Yes, P6SMB510AHM3_A/H is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's P6SMB datasheet (Rev. 09-Jan-2024). It undergoes stress testing for temperature cycling, highly accelerated life testing (HALT), and ESD robustness per automotive standards. Its 150 °C maximum junction temperature, MSL Level 1 reflow compatibility, and halogen-free construction make it appropriate for under-hood and body-control module applications.
What does the "HM3" suffix indicate in P6SMB510AHM3_A/H?
The "HM3" suffix in P6SMB510AHM3_A/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Per Vishay's ordering nomenclature, "H" indicates 7-inch tape-and-reel packaging, "M3" specifies halogen-free and RoHS-compliant materials, and the "_A/H" revision code reflects manufacturing batch and quality traceability. This distinguishes it from commercial-grade variants like E3 or M3 without automotive qualification.
How does the SMB package of P6SMB510AHM3_A/H compare thermally to larger packages like DO-201?
P6SMB510AHM3_A/H in the SMB (DO-214AA) package has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads-lower than the DO-201-based 1.5KE510A (RθJA ≈ 120–140 °C/W). While smaller than DO-201, the SMB's optimized pad layout and low-profile design enable better thermal coupling in dense SMT layouts, supporting higher power density in modern automotive and industrial PCBs.
Can P6SMB510AHM3_A/H be used in bidirectional configurations?
No, P6SMB510AHM3_A/H is a unidirectional TVS diode, as indicated by its "A" suffix and cathode band marking. Bidirectional variants in the same series use the "CA" suffix (e.g., P6SMB510CA). Using P6SMB510AHM3_A/H in a bidirectional application would result in forward conduction during negative transients, potentially causing failure. For AC or dual-polarity protection, select the explicitly rated bidirectional counterpart.
