Product details
Overview
P4SMA200A-M3/5A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, rated for 200 V standoff voltage (VWM), 210 V minimum breakdown voltage (VBR), and 274 V maximum clamping voltage (VC) at 1.1 A peak pulse current (IPPM). It delivers 400 W peak pulse power (10/1000 µs waveform) and is used to protect MOSFETs, ICs, and sensor signal lines from inductive switching transients and lightning surges in industrial and telecom equipment.
For engineers reviewing the P4SMA200A-M3/5A datasheet, P4SMA200A-M3/5A pinout, P4SMA200A-M3/5A application, or P4SMA200A-M3/5A equivalent, this device offers verified unidirectional clamping performance, halogen-free RoHS compliance (M3 suffix), AEC-Q101 qualification readiness, and compatibility with automated SMT placement on standard PCB pad layouts per JEDEC DO-214AC footprint.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (<1 µA leakage at 171 V), but triggers into low-impedance conduction when transient voltage exceeds its 210 V breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and fast response time (<1 ns).
Thermal design relies on its RθJA of 120 °C/W and RθJL of 30 °C/W, with derating applied above 25 °C ambient per Fig. 2. The cathode band identifies polarity, and operation is limited to TJ = –65 to +150 °C with 3.3 W steady-state power dissipation capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 171 V - Maximum continuous reverse operating voltage before significant leakage; defines safe working margin below clamping threshold. |
| VBR (min) | 190 V - Minimum breakdown voltage at 1 mA test current; guarantees reliable triggering no earlier than 190 V. |
| VC @ IPPM | 274 V - Clamped voltage at 1.1 A peak pulse current; determines maximum stress imposed on protected circuitry. |
| PPPM | 400 W - Peak pulse power handling (10/1000 µs waveform); defines surge energy absorption capacity. |
| IPPM | 1.1 A - Peak pulse current corresponding to VC = 274 V; used to size PCB trace width and thermal relief. |
| TJ max | +150 °C - Maximum junction temperature; sets upper limit for thermal management design in enclosed environments. |
| Package | SMA (DO-214AC) - Standard surface-mount outline with 5.0 mm × 5.0 mm copper pad requirement for full 400 W rating. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | Same VWM/VBR/VC, but SMB package (DO-214AA); 600 W PPPM, higher IPPM (1.8 A), larger footprint (4.6 × 3.9 mm vs. 4.5 × 2.7 mm). | Better suited for higher-energy surges where board space allows larger package; not drop-in compatible due to different pad layout. | Select SMBJ200A only if surge energy exceeds 400 W and PCB real estate permits SMB footprint. |
| 1.5SMC200A | Same electrical specs, but SMC (DO-214AB) package; 1500 W PPPM, 10.5 A IPPM, 7.1 × 6.2 mm body, higher thermal mass. | Used in high-reliability industrial power supplies requiring >1000 W surge handling; incompatible with SMA land pattern. | Choose 1.5SMC200A when system-level testing requires >600 W pulse rating and mechanical mounting allows larger case. |
Compared with SMBJ200A and 1.5SMC200A, P4SMA200A-M3/5A provides optimal balance of compact DO-214AC footprint, 400 W surge capability, and halogen-free compliance-making it preferred for space-constrained consumer and telecom designs where exact SMA footprint adherence is required.

FAQ
What is the maximum clamping voltage of P4SMA200A-M3/5A at its rated peak pulse current?
The maximum clamping voltage (VC) of P4SMA200A-M3/5A is 274 V at 1.1 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value defines the highest voltage that will appear across the protected circuit during a surge event, ensuring downstream components remain within safe operating limits. The P4SMA200A-M3/5A achieves this clamping performance while maintaining low incremental surge resistance and fast sub-nanosecond response.
Is P4SMA200A-M3/5A suitable for automotive applications?
P4SMA200A-M3/5A itself is commercial-grade, but the same die is qualified to AEC-Q101 when ordered as P4SMA200AHM3_B/I (halogen-free, automotive grade). The P4SMA200A-M3/5A shares identical electrical characteristics-including 190–210 V breakdown range, 274 V clamping, and 400 W pulse rating-with its automotive variant, making it suitable for prototyping and non-safety-critical automotive subsystems pending formal qualification validation.
What does the "M3" suffix indicate in P4SMA200A-M3/5A?
The "M3" suffix in P4SMA200A-M3/5A denotes halogen-free, RoHS-compliant construction per IPC-1752A and Vishay's material compliance standards. It confirms the molding compound contains no brominated flame retardants or chlorine-based additives, and the matte tin-plated leads meet JESD 22-B102 whisker resistance Class 2. This distinguishes it from the "E3" (RoHS-compliant but not halogen-free) variant.
How does the thermal resistance of P4SMA200A-M3/5A affect PCB layout?
P4SMA200A-M3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W, which requires minimum 5.0 mm × 5.0 mm copper pads per terminal to sustain full 400 W pulse rating. Reducing pad area increases RθJA, causing higher junction temperatures during repetitive surges and potential parametric shift or failure. Layout must follow Vishay's recommended DO-214AC mounting pad dimensions to ensure thermal reliability.
Can P4SMA200A-M3/5A be used in bidirectional configurations?
No-P4SMA200A-M3/5A is strictly unidirectional, as indicated by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., P4SMA200CA). Using P4SMA200A-M3/5A in reverse-biased AC applications risks catastrophic failure due to lack of symmetric breakdown behavior. For bidirectional protection at 200 V, specify P4SMA200CA-M3/5A instead.
