Product details
Overview
P6SMB510AHE3_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 rating (10/1000 μs), 0.86 A maximum peak pulse current (IPPM), and clamps transients to ≤698 V at rated surge. It is used in industrial power supplies and automotive ECUs to protect MOSFETs and microcontrollers from lightning-induced surges.
For engineers reviewing the P6SMB510AHE3_A/H datasheet, P6SMB510AHE3_A/H pinout, P6SMB510AHE3_A/H application, or P6SMB510AHE3_A/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, SMB (DO-214AA) package dimensions, clamping behavior under IEC 61000-4-5 surge conditions, and direct alternatives with documented voltage and power trade-offs.
Technical Context
The P6SMB510AHE3_A/H operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its 535–535 V breakdown range (tested at 1.0 mA). Its low incremental surge resistance ensures stable clamping during repetitive 10/1000 μs transients up to 600 W, with thermal resistance of 100 °C/W (junction-to-ambient) enabling operation up to +150 °C junction temperature.
It is RoHS-compliant and AEC-Q101 qualified (automotive-grade), marked with cathode band polarity, and built using glass-passivated junction technology for reliability. The device meets MSL level 1 per J-STD-020 and supports automated SMT placement on standard 0.2" × 0.2" copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 434 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC/AC line operating margin. |
| VBR (Breakdown Voltage) | 485–535 V at 1.0 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | ≤698 V at 0.86 A - Maximum voltage seen by protected circuit during full-rated 10/1000 μs surge; critical for downstream IC survival. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized 10/1000 μs waveform; validates compliance with IEC 61000-4-5 Level 4. |
| IPPM (Peak Pulse Current) | 0.86 A - Peak current handled at VC; determines minimum trace width and PCB layout robustness for surge path. |
| TJmax | +150 °C - Maximum junction temperature; enables use in under-hood automotive and high-ambient industrial environments. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient; informs heatsinking requirements when operating near power limits. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads. Cathode identified by black band; anode is unmarked end. Meets UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Surge current sink node | Connected to protected line (e.g., 48 V rail); conducts transient energy to ground during overvoltage. |
| Anode (unbanded end) | Reference / ground return | Typically tied to system ground or low-impedance return path; completes clamping loop during avalanche conduction. |
Key Features
| Feature | Design Value |
|---|---|

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 510 V VWM, but 400 W PPPM and SMA package (smaller, higher RθJA = 150 °C/W) | Limited to lower-energy surges; unsuitable for IEC 61000-4-5 Level 4 without parallel staging | Select when board space is constrained and surge threat level is ≤400 W; verify thermal margin at 100 °C ambient. |
| 1.5SMC510A | Same 510 V VWM, 600 W rating, but larger SMC (DO-214AB) package with lower RθJA = 60 °C/W | Better thermal performance for sustained surge duty cycles; requires 20% more PCB area | Choose for high-reliability industrial systems requiring >1000 surge events or operation above 85 °C ambient. |
Compared with P6SMB510AHE3_A/H, SMAJ510A trades peak power and thermal robustness for compactness, while 1.5SMC510A improves thermal handling at the cost of footprint-making P6SMB510AHE3_A/H the optimal balance of AEC-Q101 compliance, 600 W capability, and SMB-space efficiency.

FAQ
What is the clamping voltage of the P6SMB510AHE3_A/H at its rated peak pulse current?
The P6SMB510AHE3_A/H clamps to a maximum of 698 V at its rated peak pulse current of 0.86 A under a 10/1000 μs waveform. This value is measured and guaranteed per Vishay's datasheet (Document Number: 88370, Rev. 09-Jan-2024), and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. Engineers must ensure downstream components have sufficient voltage margin above 698 V.
Is the P6SMB510AHE3_A/H qualified for automotive applications?
Yes, the P6SMB510AHE3_A/H is AEC-Q101 qualified, as confirmed by its "HE3" suffix and documentation in the Vishay P6SMB datasheet. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and surge endurance-making P6SMB510AHE3_A/H suitable for under-hood and body electronics in passenger vehicles and commercial vehicles.
What is the standoff voltage (VWM) of the P6SMB510AHE3_A/H, and why does it matter?
The P6SMB510AHE3_A/H has a standoff voltage (VWM) of 434 V, meaning it remains non-conductive up to this reverse DC or RMS voltage. This parameter ensures reliable operation without leakage or false triggering during normal system operation-critical for protecting high-voltage rails like 48 V or 380 V DC where margin above nominal voltage is essential.
Does the P6SMB510AHE3_A/H have a bidirectional variant, and how does it differ?
No, P6SMB510AHE3_A/H is unidirectional only, indicated by the "A" suffix. Bidirectional variants use the "CA" suffix (e.g., P6SMB510CA) and suppress surges in both polarities. The unidirectional P6SMB510AHE3_A/H offers higher VBR symmetry and tighter tolerance for single-polarity protection, whereas bidirectional types are used where AC-coupled or floating lines require symmetrical clamping.
What package type does the P6SMB510AHE3_A/H use, and what are its key mechanical features?
The P6SMB510AHE3_A/H uses the SMB (DO-214AA) package: a surface-mount, low-profile plastic case measuring 0.180" × 0.130", with matte tin-plated leads solderable per J-STD-002. It features a cathode band marking, UL 94 V-0 flammability rating, and MSL Level 1 rating for 260 °C peak reflow-enabling compatibility with high-volume automated assembly without moisture sensitivity concerns.
