Overview
P4SMA200CA-E3/5A 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). It clamps transients to 274 V at 1.1 A peak pulse current and is AEC-Q101 qualified for automotive-grade surge protection on signal lines and power rails.
For engineers reviewing the P4SMA200CA-E3/5A datasheet, P4SMA200CA-E3/5A pinout, P4SMA200CA-E3/5A application, or P4SMA200CA-E3/5A equivalent, this device serves as a robust, low-profile, RoHS-compliant TVS for ESD and lightning-induced transient suppression in automotive sensor interfaces, industrial I/O modules, and telecom line protection where bidirectional clamping and MSL Level 1 reflow compatibility are required.
Technical Context
The P4SMA200CA-E3/5A operates as a bidirectional avalanche diode with symmetrical clamping behavior in both polarities, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at VWM).
Designed for transient immunity per IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (surge), it delivers 274 V clamping voltage at 1.1 A IPPM under 10/1000 µs waveform, with thermal resistance RθJA = 120 °C/W and maximum junction temperature of 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 200 V - Maximum continuous reverse voltage before conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 220 V min - Voltage at which device enters avalanche breakdown at 1 mA test current; ensures reliable triggering above normal operating range. |
| VC (Clamping Voltage) | 274 V at IPPM = 1.1 A - Peak voltage seen by protected circuit during 10/1000 µs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 400 W - Surge energy handling capability under standard 10/1000 µs waveform; sufficient for Level 4 IEC 61000-4-5 (4 kV line-to-ground). |
| ID (Reverse Leakage) | <1 µA at 200 V - Minimal DC loading on signal/power lines during normal operation; preserves signal integrity and power efficiency. |
| Package | SMA (DO-214AC) - Surface-mount package with 5.0 mm × 5.0 mm copper pad footprint; supports automated placement and J-STD-020 MSL Level 1 reflow. |
| AEC-Q101 Qualified | Yes - Validated for automotive applications including engine control units, ADAS sensors, and infotainment interfaces per stress-test requirements. |
Pinout & Package
SMA (DO-214AC) package: molded plastic body with two terminals; no polarity marking for bidirectional devices - symmetrical construction enables orientation-agnostic PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Both terminals function identically; bidirectional clamping occurs regardless of voltage polarity across the device. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., RS-485), and ungrounded power rails without polarity constraints. |
| 400 W peak pulse power | Withstands 4 kV surge per IEC 61000-4-5 (line-to-ground) when mounted on recommended 5.0 mm × 5.0 mm copper pads. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients, improving protection margin for sensitive ICs like microcontrollers and ADCs. |
| MSL Level 1 rating | Supports lead-free reflow up to 260 °C peak without preconditioning - eliminates moisture sensitivity handling overhead in SMT lines. |
| Glass passivated junction | Ensures long-term stability of VBR and leakage performance across temperature (-65 °C to +150 °C) and lifetime stress conditions. |
Applications
| Automotive Sensor Interface | Industrial PLC Analog Input |

Use Scenario: ESD protection for USB 2.0 data lines (D+/D−) and VBUS in smart home hubs and portable media players. IC Role / Device Role / Timing Role: Low-capacitance bidirectional suppressor placed adjacent to USB connector to meet IEC 61000-4-2 ±15 kV contact discharge requirement. Use Value: Sub-1 µA leakage and symmetrical clamping prevent signal distortion on high-speed differential pairs while surviving repeated ESD strikes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage 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 but requires 30% more PCB area. | Select when surge threat level exceeds 400 W or when thermal margin is constrained by ambient conditions. |
| 1.5KE200CA | Through-hole DO-15 package; identical electrical specs but lower MSL rating (not MSL Level 1) and no AEC-Q101 qualification. | Limited to non-automotive, non-reflow production environments; unsuitable for high-volume SMT lines. | Choose only for legacy through-hole designs or prototyping where reflow compatibility and automotive qualification are not required. |

The P4SMA200CA-E3/5A clamps to a maximum of 274 V at its specified peak pulse current (IPPM) of 1.1 A under the standard 10/1000 µs waveform. This value is measured with the device mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per the Vishay datasheet, and represents the worst-case voltage imposed on protected circuitry during surge events.
Is P4SMA200CA-E3/5A suitable for automotive applications?
Yes, P4SMA200CA-E3/5A is AEC-Q101 qualified and explicitly listed in Vishay's automotive-grade ordering codes (HE3/HM3 variants). Its glass-passivated junction, -65 °C to +150 °C operating range, and MSL Level 1 reflow compatibility make it suitable for under-hood and cabin applications including ADAS sensor interfaces and body control modules.
Does P4SMA200CA-E3/5A have polarity markings on the package?
No, P4SMA200CA-E3/5A is a bidirectional TVS diode and carries no polarity marking on the SMA (DO-214AC) package. The device exhibits identical electrical behavior in both directions, allowing unrestricted orientation during PCB assembly - a key advantage for differential signal protection and simplified layout.
What is the maximum reverse leakage current for P4SMA200CA-E3/5A at its standoff voltage?
At its 200 V standoff voltage (VWM), the P4SMA200CA-E3/5A exhibits a maximum reverse leakage current (ID) of 1 µA at 25 °C. This ultra-low leakage ensures minimal power loss and signal interference in high-impedance circuits such as sensor bias networks and precision analog front-ends.
Can P4SMA200CA-E3/5A be used in place of unidirectional TVS diodes?
No - P4SMA200CA-E3/5A is strictly bidirectional and must not replace unidirectional TVS diodes (e.g., P4SMA200A) in DC-biased circuits where forward conduction would cause short-circuit failure. Its symmetrical structure is intended only for AC-coupled, differential, or floating-rail applications where polarity reversal is possible or expected.
