Product details
Overview
P4SMA10CA-M3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on signal and power lines. It features 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage (VC) at 27.6 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor signal lines in industrial and telecom equipment.
For engineers reviewing the P4SMA10CA-M3/61 datasheet, P4SMA10CA-M3/61 pinout, P4SMA10CA-M3/61 application, or P4SMA10CA-M3/61 equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VWM = 1.45), AEC-Q101 qualification readiness (M3 suffix), halogen-free RoHS compliance, and compatibility with automated SMT placement on standard 0.2" × 0.2" copper pads.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with breakdown voltage (VBR) of 10.5–11.6 V at 1 mA test current and reverse leakage current ≤10 µA at 8.55 V standoff. Its glass-passivated junction ensures stable avalanche characteristics and fast response time (<1 ns) to ESD and surge events.
Thermal performance is defined by 120 °C/W junction-to-ambient thermal resistance (RθJA) and 30 °C/W junction-to-lead (RθJL), enabling reliable operation up to 150 °C junction temperature. The device meets MSL Level 1 per J-STD-020 and supports peak forward surge current of 40 A (8.3 ms half-sine) only in unidirectional variants - not applicable here due to bidirectional construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff) | 8.55 V - maximum continuous reverse voltage before significant conduction begins; defines operating margin below clamping threshold |
| VBR (Breakdown) | 10.5–11.6 V at 1 mA - guaranteed avalanche initiation range; ensures predictable turn-on during transients |
| VC (Clamping) | 14.5 V at 27.6 A IPPM - peak voltage seen by protected circuit during 10/1000 µs surge; critical for IC-level protection |
| PPPM | 400 W - peak transient power handling capacity under standardized 10/1000 µs waveform; enables robust surge immunity |
| ID (Leakage) | ≤10 µA at VWM - minimal standby power loss and signal integrity impact in high-impedance circuits |
| Package | SMA (DO-214AC) - industry-standard SMD outline with 5.28 mm length, 4.50 mm width, and 2.29 mm height; optimized for reflow and wave soldering |
| Compliance | Halogen-free, RoHS-compliant (M3 suffix); UL 94 V-0 molding compound; JESD201 Class 2 whisker resistance |
Pinout & Package
SMA (DO-214AC) package: surface-mount, two-terminal, symmetrical bidirectional device with no polarity marking; terminals are matte tin-plated for solderability per J-STD-002 and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Either terminal serves as anode or cathode depending on transient polarity; no fixed polarity designation |
| Terminal 2 | Anode/Cathode (bidirectional) | Electrically identical to Terminal 1; symmetric conduction enables AC/DC line protection without orientation constraints |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines (e.g., RS-485, CAN, USB D+/D−) without polarity concerns |
| 400 W peak pulse power | Withstands IEC 61000-4-5 Level 4 surges (4 kV, 2 Ω source) when mounted on 5.0 mm × 5.0 mm copper pads |
| Low clamping ratio (VC/VWM = 1.45) | Minimizes overvoltage stress on downstream components compared to higher-ratio TVS devices |
| MSL Level 1 rating | Allows unlimited floor life and reflow processing at peak temperature up to 260 °C without baking |

Applications
| Industrial Sensor Interfaces | Automotive Body Control Modules |
|---|---|
|
Use Scenario: Protecting analog output lines (e.g., 4–20 mA current loops) from inductive switching transients in PLC I/O modules. IC Role / Device Role / Timing Role: Bidirectional TVS placed across signal and return paths to clamp ±1 kV EFT bursts without rectification or polarity biasing. Use Value: Prevents latch-up or damage to precision op-amps and ADC front-ends while maintaining <10 µA leakage at 8.55 V operating voltage. |
Use Scenario: Safeguarding LIN bus transceivers and microcontroller GPIOs against load dump and jump-start induced surges in door module ECUs. IC Role / Device Role / Timing Role: Standoff voltage (8.55 V) aligns with 12 V automotive nominal rail; clamping at 14.5 V avoids triggering reset thresholds during battery transients. Use Value: Enables use without external series impedance or voltage dividers - direct placement between LIN line and ground reduces BOM count and PCB area. |
| Telecom Power Feeds | Consumer USB Port Protection |
|
Use Scenario: Shielding PoE-powered Ethernet PHYs from lightning-induced common-mode surges on twisted-pair cables. IC Role / Device Role / Timing Role: Paired bidirectional TVS units (one per pair) suppress differential and common-mode transients simultaneously. Use Value: 400 W rating sustains multiple 10/1000 µs surges without degradation; low RθJL (30 °C/W) prevents thermal runaway during repetitive events. |
Use Scenario: Guarding USB 2.0 data lines (D+, D−) against ESD per IEC 61000-4-2 ±15 kV contact discharge. IC Role / Device Role / Timing Role: Low capacitance (typ. 150 pF at 0 V, not specified but consistent with SMA-family profile) preserves signal integrity up to 480 Mbps. Use Value: Symmetric clamping eliminates need for dual unidirectional devices; M3 suffix ensures compliance with EU RoHS and JEITA EG-02 standards. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | Higher PPPM (600 W), larger SMB (DO-214AA) package (5.3 mm × 4.6 mm vs. SMA's 4.5 mm × 2.3 mm), same VWM/VC specs | Better surge handling but requires 30% more board area; preferred for high-reliability power rail protection | Select SMBJ10CA when peak surge energy exceeds 400 W or when thermal derating margin is critical |
| 1.5KE10CA | Through-hole TO-218 package, 1500 W PPPM, higher VC (17.5 V), slower response due to parasitic inductance | Not suitable for high-speed data lines; used in AC mains input stages or legacy board designs | Choose 1.5KE10CA only for cost-sensitive, non-SMT legacy systems where board space and speed are secondary |
Compared with P4SMA10CA-M3/61, SMBJ10CA offers superior power handling in a slightly larger SMD footprint, while 1.5KE10CA trades miniaturization and speed for raw energy absorption in through-hole form - making P4SMA10CA-M3/61 optimal for space-constrained, high-frequency signal line protection requiring halogen-free compliance.

FAQ
What is the clamping voltage of P4SMA10CA-M3/61 at its rated peak pulse current?
The P4SMA10CA-M3/61 has a maximum clamping voltage (VC) of 14.5 V at 27.6 A peak pulse current (IPPM) under the 10/1000 µs waveform condition. This value is measured per Figure 1 in Vishay document 88367 and represents the upper limit of voltage imposed on protected circuitry during standardized surge testing - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is P4SMA10CA-M3/61 suitable for automotive applications?
P4SMA10CA-M3/61 carries the M3 suffix indicating halogen-free, RoHS-compliant construction and meets JESD201 Class 2 whisker resistance, but it is not AEC-Q101 qualified. For automotive use, Vishay specifies P/NHM3_X variants (e.g., P4SMA10CAHM3_A/H); therefore, P4SMA10CA-M3/61 is recommended for industrial and consumer applications unless explicitly validated per AEC-Q101 test plan.
How does the bidirectional design of P4SMA10CA-M3/61 affect its PCB layout?
The bidirectional nature of P4SMA10CA-M3/61 eliminates polarity constraints - no cathode band marking exists, and either terminal functions identically under positive or negative transients. This allows placement across any differential or floating node (e.g., RS-485 A/B, USB D+/D−) without orientation verification, reducing assembly errors and simplifying layout for AC-coupled interfaces.
What is the thermal resistance of P4SMA10CA-M3/61, and how does it impact power derating?
P4SMA10CA-M3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W and junction-to-lead (RθJL) of 30 °C/W. At ambient temperatures above 25 °C, its 400 W peak pulse power must be derated per Figure 2 in document 88367 - e.g., at 75 °C ambient, usable PPPM drops to ~280 W - requiring careful thermal pad design and airflow consideration in enclosed enclosures.
Does P4SMA10CA-M3/61 have a specified junction capacitance for high-speed data line protection?
Junction capacitance is not explicitly listed for P4SMA10CA-M3/61 in the provided documentation; however, the P4SMA family exhibits typical values of ~150 pF at 0 V (inferred from adjacent part curves in Figure 4 of document 88367). For USB 2.0 or CAN FD applications, this capacitance may affect signal rise/fall times - designers should verify eye diagram integrity in final layout rather than relying solely on datasheet typicals.
