Product details
Overview
P4SMA510A-M3/5A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features a 485 V minimum breakdown voltage (VBR), 434 V maximum standoff voltage (VWM), 698 V maximum clamping voltage (VC) at 0.43 A peak pulse current (IPPM), and 400 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P4SMA510A-M3/5A datasheet, P4SMA510A-M3/5A pinout, P4SMA510A-M3/5A application, or P4SMA510A-M3/5A equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance under surge conditions, and AEC-Q101-qualified halogen-free alternatives for automotive-grade design-in.
Technical Context
The P4SMA510A-M3/5A operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its 485–535 V breakdown range at 1 mA test current. Its low incremental surge resistance ensures stable clamping during fast transients, while glass-passivated junction enhances reliability under repetitive surge stress.
Thermal performance is defined by RθJA = 120 °C/W (junction-to-ambient) and RθJL = 30 °C/W (junction-to-lead), with maximum junction temperature of +150 °C. Derating above 25 °C ambient follows Fig. 2 in the datasheet, and peak pulse power drops to 300 W for devices rated above 91 V - applicable here due to its 510 V nominal rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 485 V / 535 V at IT = 1 mA - defines precise avalanche initiation threshold for overvoltage detection |
| VWM | 434 V max - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 698 V at 0.43 A - clamped voltage seen by protected circuit during 10/1000 µs transient |
| PPPM | 400 W - peak pulse power handling per 10/1000 µs waveform, derated to 300 W above 91 V rating |
| IPPM | 0.43 A - peak pulse current corresponding to VC = 698 V, critical for PCB trace sizing |
| TJ max | +150 °C - maximum allowable junction temperature; requires thermal pad layout per DO-214AC spec |
| Package | SMA (DO-214AC) - surface-mount package with 0.208" x 0.157" footprint, MSL Level 1, 260 °C reflow compatible |
Pinout & Package

Applications
| Industrial Power Supply Protection | Automotive Sensor Interface Protection |
|---|---|

IC Role / Device Role / Timing Role: TVS mounted at connector entry point to shunt fast-rising edges before reaching precision ADC front-end. Use Value: Sub-1 ns response time limits voltage excursion to safe levels for 5 V tolerant analog inputs, preventing latch-up in automotive SoCs. |
| Telecom AC/DC Front-End Protection | Renewable Energy Inverter DC Link |
|
Use Scenario: Secondary-side 380 V DC bus in telecom rectifier subjected to lightning-induced surges.

Use Scenario: High-voltage DC link (400–600 V) in solar string inverters exposed to grid-switching transients. IC Role / Device Role / Timing Role: Parallel-mounted TVS across DC bus capacitors to suppress dV/dt spikes during IGBT commutation. Use Value: Limits voltage overshoot to <700 V, reducing stress on 650 V SiC modules and extending capacitor lifetime in outdoor installations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ510A-M3/57 | Same VBR range (485–535 V), but SMB package (DO-214AA); 600 W PPPM, higher IPPM (0.67 A), larger footprint | Better suited for higher-energy surges where board space allows larger package; not drop-in replacement due to different pad layout | Select when surge energy exceeds 400 W and thermal mass supports SMB mounting. |
| P6SMB510A-M3/57 | 600 W PPPM, same VBR, but larger SMC (DO-214AB) package; higher thermal mass, RθJA = 65 °C/W | Preferred for high-reliability industrial inverters requiring >100,000 surge cycles; requires redesign of footprint and stencil | Choose for mission-critical 600 V DC systems where long-term clamping stability outweighs size constraints. |
Compared with SMBJ510A-M3/57 and P6SMB510A-M3/57, the P4SMA510A-M3/5A offers the smallest footprint among 510 V-class TVS diodes while maintaining full AEC-Q101 qualification in halogen-free form - ideal for space-constrained automotive and telecom modules where 400 W surge handling suffices.

FAQ
What is the maximum clamping voltage of the P4SMA510A-M3/5A under standard test conditions?
The P4SMA510A-M3/5A has a maximum clamping voltage (VC) of 698 V at 0.43 A peak pulse current (IPPM) using the 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet 88367 and reflects worst-case voltage seen by protected circuitry during surge events - critical for validating margin against downstream device breakdown ratings in the P4SMA510A-M3/5A application.
Is the P4SMA510A-M3/5A suitable for automotive applications?
Yes - the P4SMA510A-M3/5A is halogen-free and RoHS-compliant, and its AEC-Q101-qualified variant (P4SMA510AHM3_B/I) is explicitly certified for automotive use. While the base P4SMA510A-M3/5A itself carries the M3 halogen-free designation and meets MSL Level 1 reflow specs, full automotive qualification requires the HM3_B suffix; always verify part marking and ordering code for AEC-Q101 compliance in the P4SMA510A-M3/5A design-in.
What is the standoff voltage rating for the P4SMA510A-M3/5A?
The P4SMA510A-M3/5A has a maximum standoff voltage (VWM) of 434 V, meaning it remains non-conductive up to this DC or RMS voltage level with leakage current limited to ≤1 µA. This parameter ensures reliable operation on 400 V-class DC rails - such as telecom secondary outputs or solar inverter DC links - without false triggering, making it a precise fit for the P4SMA510A-M3/5A's intended protection role.
Does the P4SMA510A-M3/5A have bidirectional capability?
No - the P4SMA510A-M3/5A is a unidirectional TVS diode, indicated by the "A" suffix (not "CA"). It conducts only in reverse bias above VBR; forward conduction follows standard silicon diode behavior. For bidirectional protection at this voltage level, Vishay specifies P4SMA510CA-M3/5A - a distinct part with symmetrical clamping in both polarities, not interchangeable with the P4SMA510A-M3/5A without circuit redesign.
What package type does the P4SMA510A-M3/5A use, and what are its key mechanical features?
The P4SMA510A-M3/5A uses the SMA (DO-214AC) surface-mount package: 0.208" × 0.157" body, matte tin-plated leads compliant with J-STD-002, and UL 94 V-0 molding compound. Its low-profile design supports automated placement, and the M3 suffix confirms halogen-free construction. The cathode is marked by a band - essential for correct orientation during P4SMA510A-M3/5A PCB layout and assembly.
