Overview
P4SMA200CA-M3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, rated for 200 V standoff voltage (VWM), 220 V minimum breakdown voltage (VBR), and 400 W peak pulse power (10/1000 µs waveform). It clamps transients to ≤274 V at 1.1 A peak pulse current and is used for protecting signal lines and power rails in industrial sensor interfaces and telecom equipment.
For engineers reviewing the P4SMA200CA-M3/61 datasheet, P4SMA200CA-M3/61 pinout, P4SMA200CA-M3/61 application, or P4SMA200CA-M3/61 equivalent, key selection criteria include bidirectional clamping capability, 274 V max clamping voltage at 1.1 A, -65 °C to +150 °C operating temperature range, halogen-free RoHS compliance (M3 suffix), and compatibility with automated SMT placement on standard PCB pads.
Technical Context
The P4SMA200CA-M3/61 operates as a bidirectional avalanche diode, symmetrically clamping voltage transients in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1 µA at 171 V).
Designed for transient suppression per IEC 61000-4-2/4-4/4-5, it delivers 400 W peak pulse power (derated to 300 W above 91 V), with thermal resistance of 120 °C/W (junction-to-ambient) and 30 °C/W (junction-to-lead), enabling reliable operation under repetitive surge conditions when mounted on 5.0 mm × 5.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 171 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 200–220 V at 1 mA - Confirmed avalanche onset range; ensures predictable clamping initiation across production lot. |
| VC (Clamping Voltage) | 274 V at IPPM = 1.1 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case transient; critical for IC-level protection. |
| PPPM (Peak Pulse Power) | 400 W - Sustains single 10/1000 µs surges up to this energy level; derates to 300 W above 91 V per spec. |
| ID (Reverse Leakage) | <1 µA at VWM - Minimal standby power loss and signal integrity impact in high-impedance circuits. |
| TJ max. | +150 °C - Enables use in under-hood automotive modules and industrial enclosures with elevated ambient temperatures. |
| Package | SMA (DO-214AC) - Standardized surface-mount outline with 5.0 mm × 5.0 mm pad footprint; supports J-STD-020 MSL Level 1 handling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | Same VWM/VBR/VC specs but in larger SMB (DO-214AA) package; 600 W PPPM rating. | Higher power handling suits higher-energy surges; requires larger PCB area and different pad layout. | Select when system-level surge testing exceeds 400 W or when thermal margin is constrained. |
| 1.5SMC200CA | Same electrical specs but in SMC (DO-214AB) package; 1500 W PPPM, higher IFSM (200 A). | Designed for primary-level protection in power entry stages; not optimized for signal-line density. | Choose for front-end AC/DC input protection where board space allows and clamping speed is secondary to energy absorption. |
Compared with SMBJ200CA and 1.5SMC200CA, the P4SMA200CA-M3/61 offers optimal balance of compact SMA footprint, 400 W surge capability, and low-profile assembly-making it preferred for space-constrained signal-path protection where moderate energy levels dominate.

FAQ
What is the maximum clamping voltage of the P4SMA200CA-M3/61 under standard test conditions?
The P4SMA200CA-M3/61 has a maximum clamping voltage (VC) of 274 V when subjected to a 10/1000 µs waveform at a peak pulse current (IPPM) of 1.1 A. This value is measured per industry-standard transient test conditions and represents the highest voltage the device allows to pass through to the protected circuit during surge events. The P4SMA200CA-M3/61 maintains this clamping performance consistently across its specified operating temperature range.
Is the P4SMA200CA-M3/61 suitable for automotive applications?
The P4SMA200CA-M3/61 is a commercial-grade device with halogen-free RoHS compliance (M3 suffix) but is not AEC-Q101 qualified. However, Vishay offers AEC-Q101 variants in the same P4SMA family-P4SMA200CAHM3_B/H or P4SMA200CAHM3_B/I-with identical electrical specs and enhanced reliability screening. For automotive use, specify the HM3_B suffix; the P4SMA200CA-M3/61 itself is best suited for industrial and telecom applications.
How does the bidirectional design of the P4SMA200CA-M3/61 affect PCB layout?
The P4SMA200CA-M3/61 has no polarity marking and functions identically in either orientation, simplifying PCB layout and eliminating orientation errors during automated placement. Engineers can route it between any two nodes requiring symmetrical transient suppression-such as line-to-ground or line-to-line-without checking cathode band alignment. This reduces assembly risk and supports flexible routing in dense layouts where space is limited.
What is the thermal resistance of the P4SMA200CA-M3/61, and how does it impact power dissipation?
The P4SMA200CA-M3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W and junction-to-lead resistance (RθJL) of 30 °C/W when mounted on 5.0 mm × 5.0 mm copper pads. These values mean that under continuous DC conditions, the device dissipates only 3.3 W (PD rating), but during short transients, heat is conducted rapidly through leads-enabling full 400 W pulse handling. Layout must follow recommended pad dimensions to achieve these thermal metrics.
Does the P4SMA200CA-M3/61 meet moisture sensitivity level (MSL) requirements for lead-free reflow?
Yes, the P4SMA200CA-M3/61 meets MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. This means it can be processed in standard lead-free reflow ovens without baking or special handling-reducing manufacturing complexity and cost. The device's construction uses glass-passivated junctions and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
