Product details
Overview
P6SMB510AHM3_D/I 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 minimum breakdown voltage (VBR), 434 V maximum standoff 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 DC bus protection for industrial power supplies and EV charging interfaces.
For engineers reviewing the P6SMB510AHM3_D/I datasheet, P6SMB510AHM3_D/I pinout, P6SMB510AHM3_D/I application, or P6SMB510AHM3_D/I equivalent, key selection criteria include its AEC-Q101 qualification, SMB (DO-214AA) package compatibility, unidirectional polarity with cathode band marking, and verified clamping performance under repetitive 10/1000 µs surges up to 600 W.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM (434 V), it avalanches at VBR (485–535 V) and limits transient voltage to ≤698 V at IPPM. Its glass-passivated junction ensures stable leakage (<1 µA at VWM) and fast response (<1 ns).
Designed for automotive-grade reliability, P6SMB510AHM3_D/I meets AEC-Q101 stress tests and is halogen-free, RoHS-compliant, and MSL Level 1 (260 °C reflow). Thermal resistance is RθJA = 100 °C/W and RθJL = 20 °C/W, supporting operation from –65 °C to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff) | 434 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC bus operating margin. |
| VBR (Breakdown) | 485–535 V at 1 mA - Avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping) | ≤698 V at 0.86 A - Peak voltage seen by protected circuit during 10/1000 µs surge; determines downstream component stress. |
| PPPM | 600 W - Surge energy handling capacity per 10/1000 µs waveform; supports IEC 61000-4-5 Level 4 compliance. |
| IPPM | 0.86 A - Peak surge current corresponding to VC; used to size PCB trace width and thermal relief. |
| TJ max. | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments without derating. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height; compatible with automated placement. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL Level 1, 260 °C peak reflow profile. Cathode indicated by band on body; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Reverse-biased avalanche terminal | Connected to protected line; conducts surge current to ground when VREV > VWM. |
| Anode (unbanded end) | Reference/ground return path | Typically tied to system ground or low-impedance return; completes shunt path during clamping. |

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/VBR/VC specs but lower PPPM (400 W), non-AEC-Q101, standard commercial grade. | Lacks automotive qualification and halogen-free certification; suitable only for non-automotive industrial use. | Select SMAJ510A only if AEC-Q101 and halogen-free compliance are not required and surge energy is ≤400 W. |
| SMCJ510A | Higher PPPM (1500 W), same VWM/VBR, but larger SMC (DO-214AB) package (7.11 mm × 6.22 mm). | Requires PCB layout change due to 40% larger footprint and higher thermal mass; better for extreme surge environments. | Choose SMCJ510A when system-level testing requires >600 W surge margin and board space allows SMC package. |
Compared with SMAJ510A and SMCJ510A, P6SMB510AHM3_D/I uniquely balances AEC-Q101 qualification, halogen-free compliance, 600 W capability, and compact SMB footprint-making it optimal for space-constrained automotive and industrial HV designs where certification and reliability are mandatory.

FAQ
What is the maximum clamping voltage of P6SMB510AHM3_D/I at its rated peak pulse current?
The maximum clamping voltage (VC) of P6SMB510AHM3_D/I is 698 V when subjected to its rated peak pulse current of 0.86 A under a 10/1000 µs waveform. This value is measured per JEDEC standards and guarantees that downstream components see no more than 698 V during surge events. The P6SMB510AHM3_D/I achieves this clamping performance while maintaining low incremental resistance, making it suitable for protecting sensitive high-voltage gate drivers and controllers.
Is P6SMB510AHM3_D/I qualified for automotive applications?
Yes, P6SMB510AHM3_D/I is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's P6SMB datasheet (Rev. 09-Jan-2024, Doc. #88370). It has passed stress tests including high-temperature reverse bias, temperature cycling, and mechanical shock-validating its use in engine control units, battery disconnect units, and on-board chargers. The P6SMB510AHM3_D/I also meets halogen-free and RoHS requirements for automotive supply chains.
What does the "D/I" suffix mean in P6SMB510AHM3_D/I?
The "D" in P6SMB510AHM3_D/I indicates AEC-Q101 qualification for high-voltage variants (250 V to 540 V), while "I" denotes packaging in 13-inch diameter tape-and-reel format with 3200 units per reel. This ordering code confirms the part is halogen-free (HM3), automotive-qualified (D), and supplied in high-volume industrial packaging (I). The P6SMB510AHM3_D/I thus combines reliability, compliance, and logistics readiness for production-scale deployment.
Can P6SMB510AHM3_D/I be used in bidirectional configurations?
No, P6SMB510AHM3_D/I is a unidirectional TVS diode, as indicated by the absence of "C" in its part number and its specification for VWM and VBR in reverse-bias only. Bidirectional versions (e.g., P6SMB510CHM3_D/I) exist in the same family but have distinct electrical characteristics and marking. Using P6SMB510AHM3_D/I in bidirectional circuits risks forward conduction and failure; always verify polarity marking (cathode band) and select the correct variant for AC or differential-line protection.
What is the thermal resistance of P6SMB510AHM3_D/I, and how does it affect PCB layout?
P6SMB510AHM3_D/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead (RθJL) of 20 °C/W. These values assume mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain TJ ≤150 °C under worst-case 5.0 W steady-state dissipation, designers must provide adequate copper area and avoid thermal bottlenecks. The P6SMB510AHM3_D/I's SMB package allows efficient heat transfer through its leads, but thermal relief design remains critical for surge-heavy applications.
