Product details
Overview
P4SMA510AHE3_ALL from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, rated for 510 V breakdown voltage (VBR = 485–535 V at 1 mA), 400 W peak pulse power (10/1000 µs), and clamping voltage of 698 V at 0.43 A. It provides robust overvoltage protection for high-voltage DC rails in industrial power supplies and telecom rectifier stages.
For engineers reviewing the P4SMA510AHE3_ALL datasheet, P4SMA510AHE3_ALL pinout, P4SMA510AHE3_ALL application, or P4SMA510AHE3_ALL equivalent, this device is selected for high-VWM (>434 V) transient suppression where low leakage (<1 µA at VWM), AEC-Q101 qualification, and MSL Level 1 reflow compatibility are required.
Technical Context
This TVS operates as a unidirectional clamping device with cathode-banded polarity, leveraging glass-passivated junction technology for stable avalanche behavior and fast response (<1 ns). Its 120 °C/W junction-to-ambient thermal resistance requires careful PCB copper pad design (0.2" × 0.2") to sustain 400 W pulses.
The device meets UL 497B recognition (QVGQ2) and is qualified to AEC-Q101 for automotive-grade reliability. It exhibits a +0.110 %/°C temperature coefficient of VBR, enabling predictable voltage drift across –65 °C to +150 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 485 V / 535 V at 1 mA - defines precise avalanche onset window for reliable clamping threshold setting |
| VWM | 434 V - maximum continuous reverse working voltage before leakage exceeds 1 µA |
| VC @ IPPM | 698 V at 0.43 A - clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPPM | 400 W - peak pulse power handling capability under standard lightning-surge waveform |
| IFSM | 40 A - surge current rating for 8.3 ms half-sine wave, supporting inrush and fault transients |
| TJ max | +150 °C - maximum junction temperature enabling operation in high-ambient environments |
| Package | SMA (DO-214AC) - industry-standard SMD outline with 5.28 mm length, 4.50 mm width, and 2.29 mm height |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ510AHE3_A | Same VBR range (485–535 V), but SMB (DO-214AA) package - 20 % larger footprint, 100 W lower PPPM (300 W) | Limited to lower-energy surge environments; not suitable for 400 W lightning test profiles | Select when board space allows larger package and peak power demand is ≤300 W |
| SMCJ510AHE3_A | Same VBR, but SMC (DO-214AB) package - 400 W PPPM, 2× higher IPPM (0.87 A), 50 % higher thermal mass | Better suited for repeated surge duty cycles and higher ambient temperatures due to lower RθJA | Prefer for high-reliability industrial systems requiring extended surge endurance and thermal margin |
Compared with P4SMA510AHE3_ALL, SMBJ510AHE3_A offers reduced surge capacity in a larger package, while SMCJ510AHE3_A delivers identical clamping performance with superior thermal handling and surge repetition capability - making it ideal for mission-critical HV DC links.

FAQ
What is the maximum clamping voltage of P4SMA510AHE3_ALL under a 10/1000 µs surge?
The P4SMA510AHE3_ALL clamps to a maximum of 698 V at its rated peak pulse current of 0.43 A under the standardized 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet 88367 and reflects worst-case dynamic impedance during surge conduction. The clamping voltage ensures downstream components see limited overvoltage stress during transient events.
Is P4SMA510AHE3_ALL suitable for automotive applications?
Yes, P4SMA510AHE3_ALL is AEC-Q101 qualified and carries the HE3 suffix denoting RoHS-compliant and automotive-grade construction. It has passed stress tests including high-temperature reverse bias, temperature cycling, and mechanical shock per AEC-Q101 Rev D. Its +150 °C max junction temperature and MSL Level 1 rating support under-hood and powertrain use cases.
What does the "HE3" suffix indicate in P4SMA510AHE3_ALL?
The "HE3" suffix in P4SMA510AHE3_ALL specifies RoHS-compliant construction with AEC-Q101 qualification and matte tin-plated leads meeting J-STD-002 solderability. It distinguishes this automotive-grade variant from commercial E3 (RoHS only) and HM3 (halogen-free + AEC-Q101) versions. The "ALL" suffix denotes full documentation coverage across all revision codes (e.g., A, B).
How does P4SMA510AHE3_ALL compare to bidirectional TVS diodes like P4SMA510CA?
P4SMA510AHE3_ALL is unidirectional and features a cathode band for polarity-sensitive placement, whereas P4SMA510CA is bidirectional with no polarity marking and symmetric clamping in both directions. The unidirectional version offers lower leakage (<1 µA at 434 V) and is preferred for DC rail protection; the bidirectional type suits AC-coupled or floating signal lines where polarity reversal may occur.
What PCB layout guidance applies to P4SMA510AHE3_ALL for optimal thermal performance?
For reliable 400 W pulse handling, Vishay specifies mounting P4SMA510AHE3_ALL on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, per Figure 1 in datasheet 88367. Use internal ground/power planes connected via multiple vias to enhance heat spreading. Avoid narrow traces between the device and pads to minimize inductance and resistive heating during surge events.
