Product details
Overview
P4SMA10CA-M3/5A from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping ESD and surge transients on signal/power lines. It features 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage at 27.6 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, sensor interfaces, and ICs in industrial and automotive electronics.
For engineers reviewing the P4SMA10CA-M3/5A datasheet, P4SMA10CA-M3/5A pinout, P4SMA10CA-M3/5A application, or P4SMA10CA-M3/5A equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VWM = 1.45), AEC-Q101 qualification eligibility (via HM3 suffix), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
The P4SMA10CA-M3/5A operates as a bidirectional avalanche diode, symmetrically clamping voltage surges above ±10.5 V breakdown (VBR min/max = 9.5–10.5 V at 1 mA) in both polarities. Its glass-passivated junction ensures stable leakage (<10 µA at VWM) and fast response time (<1 ns), critical for protecting high-speed sensor lines and microcontroller I/O pins.
Thermally, it exhibits RθJA = 120 °C/W and RθJL = 30 °C/W, enabling reliable operation up to TJ = 150 °C. Derating begins above TA = 25 °C per Figure 2, with 300 W peak power maintained above 91 V devices - though P4SMA10CA-M3/5A retains full 400 W rating due to its 10 V nominal class.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff) | 10 V - Maximum continuous reverse voltage before conduction; defines safe operating margin for 12 V rail protection. |
| VBR (Breakdown) | 9.5–10.5 V at 1 mA - Tight tolerance ensures predictable clamping onset across temperature and unit variation. |
| VC (Clamping) | 14.5 V at IPPM = 27.6 A - Limits downstream voltage stress during 10/1000 µs surge; clamping ratio = 1.45. |
| PPPM | 400 W (10/1000 µs) - Sustains single high-energy transients common in inductive switching or lightning-induced coupling. |
| ID (Leakage) | <10 µA at VWM - Minimizes standby power loss and avoids false triggering in low-current sensor circuits. |
| Package | SMA (DO-214AC) - Surface-mount outline with 5.0 mm × 5.0 mm thermal pad footprint; MSL Level 1, 260 °C reflow compatible. |
| AEC-Q101 | Qualified via HM3 suffix - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, bidirectional device with no polarity marking. Terminals are matte tin-plated, solderable per J-STD-002 and JESD 22-B102. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | Conducts during negative surges; symmetrical with cathode for bidirectional clamping. |
| Cathode | Transient current entry (positive polarity) | Conducts during positive surges; identical electrical behavior to anode in CA-series devices. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Equal VBR and VC in both directions - eliminates need for polarity-aware layout in differential or AC-coupled lines. |
| 400 W peak pulse power | Withstands 10/1000 µs surges up to 27.6 A - meets IEC 61000-4-5 Level 4 (4 kV) when properly laid out. |
| Low clamping ratio (VC/VWM) | 1.45 - Delivers tighter voltage limiting than typical 1.6–2.0 ratios, reducing stress on protected 3.3 V or 5 V ICs. |
| Halogen-free & RoHS-compliant (M3) | Meets JESD201 Class 2 whisker resistance - suitable for long-life industrial and automotive applications. |
| Fast response time | <1 ns - Reacts before most semiconductor junctions fail, preserving integrity of downstream logic and analog circuitry. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

IC Role / Device Role: Fast-acting clamping diode placed between data line and chassis ground to limit transient overshoot. Use Value: Sub-1 ns response and 14.5 V VC ensure USB PHY remains within absolute maximum ratings during ESD events. |
Use Scenario: Protecting Ethernet PHY or DSL line drivers from lightning-induced surges on twisted-pair telecom interfaces. IC Role / Device Role: Differential-mode TVS across line pairs (e.g., TIP-RING) to suppress common-mode and asymmetrical transients. Use Value: Symmetrical bidirectional structure allows single-device protection without polarity concerns on AC-coupled lines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | Same VWM/VBR/VC specs but SMB (DO-214AA) package - 2.5 mm wider body, higher RθJA (150 °C/W). | Lower power density; less suitable for dense PCB layouts where SMA's smaller footprint matters. | Select SMBJ10CA only if existing layout uses SMB pads or requires higher IFSM (100 A vs. 40 A). |
| 1.5KE10CA | Through-hole DO-15 package; same 10 V VWM but 1500 W PPPM rating and higher VC (17.5 V at 85 A). | Designed for higher-energy surges; overkill for board-level signal protection, adds assembly cost and space. | Choose 1.5KE10CA only for primary AC mains or telecom line protection where PCB area and SMT are secondary concerns. |
Compared with SMBJ10CA and 1.5KE10CA, the P4SMA10CA-M3/5A delivers optimal balance of compact SMA footprint, 400 W surge handling, and low 14.5 V clamping - making it preferred for space-constrained, high-density signal-line protection in automotive and industrial control units.

FAQ
What is the clamping voltage of P4SMA10CA-M3/5A at its rated peak pulse current?
The P4SMA10CA-M3/5A has a maximum clamping voltage (VC) of 14.5 V at its peak pulse current (IPPM) of 27.6 A, measured under the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and reflects the actual voltage seen by protected circuitry during surge events - critical for ensuring downstream ICs remain within their absolute maximum ratings.
Is P4SMA10CA-M3/5A suitable for automotive applications?
Yes, P4SMA10CA-M3/5A is qualified to AEC-Q101 when ordered with the HM3 suffix (e.g., P4SMA10CAHM3_A/I). The M3 suffix indicates halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance - meeting automotive reliability requirements for under-hood and cabin electronics, including sensor interfaces and body control modules.
How does the bidirectional design of P4SMA10CA-M3/5A affect PCB layout?
The P4SMA10CA-M3/5A has no polarity marking and identical electrical characteristics in both directions, eliminating orientation constraints during placement. This simplifies layout for differential signals (e.g., RS-485, CAN), AC-coupled lines, or any application where voltage polarity reversal is possible - reducing assembly errors and enabling symmetric routing without dedicated silkscreen indicators.
What thermal derating applies to P4SMA10CA-M3/5A above 25 °C ambient?
P4SMA10CA-M3/5A follows the derating curve in Figure 2 of Vishay document 88367: peak pulse power decreases linearly from 400 W at 25 °C to zero at 150 °C junction temperature. At 85 °C ambient (assuming typical board thermal resistance), usable PPPM drops to approximately 280 W - requiring appropriate copper pad sizing and airflow consideration in sealed enclosures.
Can P4SMA10CA-M3/5A replace unidirectional P4SMA10A in existing designs?
No - P4SMA10CA-M3/5A is bidirectional and lacks polarity marking, while P4SMA10A is unidirectional with cathode band identification. Substituting without layout review risks incorrect biasing in DC-coupled circuits. Use P4SMA10CA-M3/5A only where bidirectional clamping is required or verified compatible with system grounding and signal swing.
