Product details
Overview
P4SMA47CA-M3/61 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on signal and power lines. It features a 47 V breakdown voltage (VBR = 44.7–49.4 V at 1 mA), 400 W peak pulse power (10/1000 µs), 64.8 V maximum clamping voltage at 6.2 A, and ±150 °C operating junction temperature - deployed in automotive sensor interfaces, industrial I/O protection, and telecom line surge suppression.
For engineers reviewing the P4SMA47CA-M3/61 datasheet, P4SMA47CA-M3/61 pinout, P4SMA47CA-M3/61 application, or P4SMA47CA-M3/61 equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, thermal derating curves, AEC-Q101 qualification status, and direct replacement guidance for ESD and lightning-induced surge protection design.
Technical Context
The P4SMA47CA-M3/61 operates as a symmetric, bidirectional avalanche diode with no polarity marking - its terminals function identically in both directions. It achieves clamping within <1 ns response time and exhibits low incremental surge resistance to maintain stable voltage limiting during 10/1000 µs transients.
Rated for 400 W peak pulse power below 91 V (derated to 300 W above), it dissipates 3.3 W continuously at 50 °C ambient and withstands 40 A unidirectional surge current (though not applicable here due to bidirectional configuration). Its thermal resistance is 120 °C/W junction-to-ambient on standard 5.0 mm × 5.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 44.7 V / 49.4 V at 1 mA - defines precise avalanche onset threshold for reliable bidirectional clamping |
| VWM | 40.2 V - maximum continuous reverse working voltage before leakage exceeds 1 µA |
| VC @ IPPM | 64.8 V at 6.2 A - clamped voltage during full 400 W transient, critical for downstream IC survivability |
| PPPM | 400 W (10/1000 µs waveform) - surge energy handling capacity for IEC 61000-4-5 Level 3/4 compliance |
| IPPM | 6.2 A - peak pulse current corresponding to 400 W clamping, used to size PCB trace robustness |
| TJ max. | +150 °C - enables operation in under-hood automotive or high-temperature industrial enclosures |

| Halogen-free, RoHS-compliant (M3 suffix) | Meets EU Directive 2011/65/EU and JESD201 Class 2 whisker resistance requirements |
Applications
| Automotive Sensor Interface | Industrial PLC Analog Input |
|---|---|
Use Scenario: Protecting CAN/LIN bus nodes and temperature/pressure sensors from load dump and inductive switching spikes in engine control units. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point to shunt transients before reaching MCU analog front-end or transceiver. Use Value: Maintains signal integrity under ISO 7637-2 Pulse 5a (load dump) by clamping to ≤64.8 V while surviving repeated 400 W surges. |
Use Scenario: Safeguarding 4–20 mA current loop inputs in programmable logic controllers exposed to field wiring surges and ground potential differences. IC Role / Device Role / Timing Role: Primary overvoltage clamp across input terminals, coordinated with series current-limiting resistor and optional gas discharge tube. Use Value: Limits transient voltage to 64.8 V at 6.2 A, preventing op-amp saturation and ADC latch-up during IEC 61000-4-4 EFT bursts. |
| Telecom Line Protection | Consumer USB Port ESD |
Use Scenario: Shielding Ethernet PHY interface pins (e.g., RJ45 magnetics secondary side) against lightning-induced surges in outdoor access points. IC Role / Device Role / Timing Role: Secondary-stage TVS after primary GDT or MOV, providing fast-response clamping for residual common-mode transients. Use Value: Sub-1 ns response ensures clamping occurs before 10/1000 µs surge energy damages PHY silicon, with 400 W rating covering multiple strike events. |
Use Scenario: ESD protection for USB 2.0 data lines (D+/D−) in smart home hubs subjected to ±8 kV contact discharge per IEC 61000-4-2. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp placed adjacent to connector, minimizing signal distortion on high-speed differential pairs. Use Value: Clamps ESD events to ≤64.8 V within nanoseconds, preserving signal rise/fall times while meeting USB-IF eye diagram requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ47CA | Same VBR range (44.7–49.4 V), but SMB package (DO-214AA); 600 W PPPM, higher IPPM (12.3 A), larger footprint | Better suited for higher-energy surges where board space allows larger package; not drop-in due to different pad layout | Select when system-level surge testing exceeds 400 W or when thermal margin requires lower RθJA (85 °C/W vs. 120 °C/W) |
| 1.5KE47CA | Through-hole DO-201 package; same VBR and VC, but 1500 W PPPM; higher capacitance, no AEC-Q101 qualification | Used in legacy or high-reliability non-automotive designs where manual assembly or extreme surge margin is prioritized | Choose only if SMT placement is unavailable or if 1.5 kW surge rating is mandated - not suitable for AEC-Q101 automotive programs |
Compared with SMBJ47CA and 1.5KE47CA, the P4SMA47CA-M3/61 offers optimal balance of compact SMA footprint, AEC-Q101 qualification, and 400 W surge capability - making it preferred for space-constrained automotive and industrial SMT designs requiring validated reliability and process compatibility.

FAQ
What is the breakdown voltage tolerance of P4SMA47CA-M3/61?
The P4SMA47CA-M3/61 has a specified breakdown voltage range of 44.7 V to 49.4 V at 1 mA test current, representing a ±5% tolerance around the nominal 47 V rating. This tight VBR window ensures predictable clamping onset across production lots and temperature extremes, critical for protecting sensitive 3.3 V or 5 V logic rails downstream of the P4SMA47CA-M3/61.
Is P4SMA47CA-M3/61 suitable for automotive applications?
Yes, the P4SMA47CA-M3/61 carries the HM3 suffix, confirming halogen-free, RoHS-compliant construction and full AEC-Q101 qualification for automotive use. It passes stress tests including high-temperature reverse bias (HTRB), temperature cycling, and mechanical shock - making it approved for under-hood and body-control module deployments where the P4SMA47CA-M3/61 provides certified surge resilience.
Does P4SMA47CA-M3/61 require orientation during PCB placement?
No - the P4SMA47CA-M3/61 is a bidirectional TVS diode with symmetrical terminals and no polarity marking. Either end may connect to line or ground without affecting clamping behavior. This eliminates orientation errors during automated placement and simplifies layout for differential or AC-coupled signal paths where the P4SMA47CA-M3/61 serves as a dual-direction protector.
What is the maximum clamping voltage of P4SMA47CA-M3/61 under surge conditions?
The P4SMA47CA-M3/61 clamps to a maximum of 64.8 V at its rated peak pulse current of 6.2 A (10/1000 µs waveform). This VC value is guaranteed across temperature and lifetime, enabling designers to verify that protected ICs - such as automotive MCUs or industrial ADCs - remain within absolute maximum ratings when the P4SMA47CA-M3/61 activates during surge events.
How does the M3 suffix affect P4SMA47CA-M3/61 compliance and processing?
The M3 suffix on P4SMA47CA-M3/61 indicates halogen-free, RoHS-compliant construction and JESD201 Class 2 whisker resistance - ensuring long-term solder joint integrity and environmental compliance. It also certifies compatibility with lead-free reflow profiles up to 260 °C peak, allowing seamless integration into modern SMT lines where the P4SMA47CA-M3/61 undergoes standard JEDEC J-STD-020 Level 1 processing.
