Product details
Overview
P4SMA510A-M3/61 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 1.0 mA), 400 W peak pulse power (10/1000 µs), and clamping voltage of 698 V at 0.43 A. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients in industrial power supplies and telecom interfaces.
For engineers reviewing the P4SMA510A-M3/61 datasheet, P4SMA510A-M3/61 pinout, P4SMA510A-M3/61 application, or P4SMA510A-M3/61 equivalent, this page delivers verified electrical specs, thermal derating behavior, AEC-Q101 qualification status, halogen-free RoHS compliance (M3 suffix), and real-world clamping performance under standardized surge waveforms.
Technical Context
The P4SMA510A-M3/61 operates as a unidirectional avalanche diode with glass-passivated junction, optimized for fast response (<1 ns) to transient overvoltages. Its 120 °C/W junction-to-ambient thermal resistance requires careful PCB pad layout (0.2" × 0.2" copper per terminal) to sustain 400 W peak pulse power without exceeding 150 °C maximum junction temperature.
It exhibits a +0.110 %/°C temperature coefficient of VBR, enabling predictable voltage drift across -65 °C to +150 °C operating range. The cathode band marking identifies polarity, and its 3.3 W steady-state power dissipation supports continuous protection in high-reliability DC bus monitoring applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 485 V / 535 V at 1.0 mA - defines precise avalanche onset window for reliable overvoltage triggering |
| VC @ IPPM | 698 V at 0.43 A - clamping voltage during full 10/1000 µs surge, limiting downstream stress |

Use Scenario: Protection of IGBT gate drivers and DC-link voltage sensors against commutation spikes in 400–600 V inverters. IC Role / Device Role / Timing Role: Unidirectional TVS clamps positive transients on high-side sensing nodes, preventing false triggering or latch-up. Use Value: With VC = 698 V at 0.43 A, it holds sensed voltage below 700 V during 400 W surges, preserving ADC input integrity. |
Use Scenario: Surge suppression on -48 V telecom rectifier output rails exposed to lightning-induced common-mode transients. IC Role / Device Role / Timing Role: Mounted anode-to-ground, cathode-to-rail to clamp positive excursions while blocking normal -48 V bias. Use Value: VWM = 434 V allows safe operation on 400 V+ intermediate bus stages upstream of DC-DC converters. |
| Renewable Energy Inverters | Railway Signaling Interfaces |
|
Use Scenario: Overvoltage protection on PV string combiner box monitoring circuits interfacing with 1000 V DC arrays.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ510A-M3/5B | Same VBR range (485–535 V), but SMB package (DO-214AA); 600 W PPPM rating | Higher surge rating suits higher-energy transients; larger footprint requires PCB redesign | Select when 600 W surge margin is required and board space permits SMB outline |
| 1.5KE510A | Through-hole DO-201 package; identical VBR/VC specs but 5.0 W PD and 1000 W PPPM | Not SMT-compatible; used in legacy or high-power prototyping where manual assembly is acceptable | Choose for cost-sensitive through-hole designs or where higher steady-state dissipation is needed |
Compared with SMBJ510A-M3/5B and 1.5KE510A, the P4SMA510A-M3/61 offers optimal balance of SMT compatibility, 400 W surge capability, and compact SMA footprint-ideal for space-constrained industrial DC bus monitors where AEC-Q101 and halogen-free compliance are mandatory.

FAQ
What is the clamping voltage of the P4SMA510A-M3/61 under a 10/1000 µs surge?
The P4SMA510A-M3/61 has a maximum clamping voltage (VC) of 698 V at 0.43 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value is measured with the device mounted on 0.2" × 0.2" copper pads per terminal and reflects actual voltage seen by downstream circuitry during standardized surge events. The P4SMA510A-M3/61 maintains this clamping performance across its full operating temperature range.
Is the P4SMA510A-M3/61 AEC-Q101 qualified?
Yes, the P4SMA510A-M3/61 is AEC-Q101 qualified under revision "B" for high-voltage variants (250 V to 540 V), as confirmed in Vishay's ordering information table. The "M3" suffix denotes halogen-free, RoHS-compliant construction, and the "B" revision code indicates automotive qualification. This makes the P4SMA510A-M3/61 suitable for automotive powertrain and body electronics where zero-failure reliability is mandated.
What does the "M3/61" suffix mean in P4SMA510A-M3/61?
The "M3" suffix indicates halogen-free, RoHS-compliant packaging and plating, meeting IPC-1752A material declarations. The "/61" denotes packaging in 7-inch plastic tape and reel, with 1800 units per reel. This format supports high-speed pick-and-place assembly and is traceable per Vishay's manufacturing lot coding. The P4SMA510A-M3/61 thus combines environmental compliance with automated manufacturing readiness.
How does the thermal resistance of the P4SMA510A-M3/61 affect PCB layout?
The P4SMA510A-M3/61 has a typical RθJA of 120 °C/W, meaning junction temperature rises 120 °C per watt of dissipated power without heatsinking. To sustain its 400 W peak pulse rating, Vishay specifies mounting on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Reducing pad area increases thermal impedance, risking junction overheating during repetitive surges. The P4SMA510A-M3/61 must be placed away from heat sources and with adequate copper pour for thermal relief.
Can the P4SMA510A-M3/61 be used in bidirectional protection circuits?
No-the P4SMA510A-M3/61 is a unidirectional TVS diode, identified by its cathode band marking. Bidirectional operation requires a "CA" suffix (e.g., P4SMA510CA). Using the P4SMA510A-M3/61 in reverse-biased configurations risks permanent damage due to lack of symmetrical avalanche structure. For AC-coupled or differential line protection, select a verified bidirectional variant-not the P4SMA510A-M3/61.
