Product details
Overview
P4SMA200AHE3/5A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features a 200 V standoff voltage (VWM), 210 V maximum breakdown voltage (VBR), 274 V clamping voltage at 1.1 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P4SMA200AHE3/5A datasheet, P4SMA200AHE3/5A pinout, P4SMA200AHE3/5A application, or P4SMA200AHE3/5A equivalent, key selection considerations include its AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, glass-passivated junction, and RoHS-compliant matte tin-plated leads suitable for automated SMT placement.
Technical Context
This unidirectional TVS diode operates by avalanche breakdown above its specified VBR (190–210 V), providing fast transient suppression with sub-nanosecond response time. Its clamping behavior is defined by VC = 274 V at IPPM = 1.1 A under standardized 10/1000 µs surge conditions.
The device uses a glass-passivated silicon junction for stable leakage performance (ID ≤ 1.0 µA at VWM), supports 40 A non-repetitive forward surge current (IFSM), and is rated for operation from –65 °C to +150 °C. Thermal resistance is RθJA = 120 °C/W on standard 0.2" × 0.2" copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 200 V - Maximum continuous reverse working voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 190–210 V at IT = 1.0 mA - Voltage at which avalanche conduction initiates; ensures predictable turn-on during overvoltage events. |
| 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 - Maximum transient energy absorption capability under standard 10/1000 µs waveform; enables robust protection against lightning-induced surges. |
| ID (Reverse Leakage) | ≤ 1.0 µA at VWM - Low leakage preserves system efficiency and prevents false triggering in high-impedance circuits. |
| TJ max. | +150 °C - Maximum junction temperature rating; supports reliable operation in automotive and industrial ambient environments. |
| Package | SMA (DO-214AC) - Standardized surface-mount outline with cathode band marking; compatible with JEDEC-standard reflow profiles and J-STD-002 solderability. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with matte tin-plated leads, UL 94 V-0 rated compound, polarity indicated by cathode band on unidirectional types.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to lower-potential side of protected line | Provides low-forward-voltage path during surge conduction; must be routed to ground or return path per layout guidelines. |
| Cathode | Current exit terminal in forward bias; marked with band; connected to higher-potential side | Defines directionality: conducts only when cathode voltage exceeds anode by ≥VBR; critical for correct orientation in PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for under-hood and ADAS sensor protection. |
| Glass-passivated junction | Enhances long-term stability of VBR and leakage performance across thermal and humidity stress, reducing parameter drift over lifetime. |
| 400 W peak pulse power (10/1000 µs) | Enables protection against IEC 61000-4-5 Level 3 (1 kV/2 Ω) surges without derating in typical PCB layouts with 5 mm × 5 mm copper pads. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without moisture sensitivity concerns - eliminates bake requirements prior to assembly. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns rise time), improving protection margin for sensitive CMOS inputs. |
Applications
| Industrial Motor Drive Protection | Automotive Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | Same VWM/VBR/VC ratings but in larger SMB (DO-214AA) package; 600 W PPPM rating; RθJA = 85 °C/W | Better thermal performance and higher surge capacity, but requires larger PCB footprint and different pad layout | Select when higher surge endurance or improved thermal dissipation is required and board space permits larger package |
| 1.5KE200A | Through-hole TO-218 package; same electrical specs but higher IFSM (125 A); no AEC-Q101 qualification | Not suitable for automotive or high-reliability SMT production; limited to prototyping or legacy through-hole designs | Choose only for manual assembly or cost-sensitive non-automotive applications where AEC-Q101 is not mandated |
Compared with SMBJ200A and 1.5KE200A, P4SMA200AHE3/5A offers optimal balance of AEC-Q101 compliance, compact SMA footprint, and verified 400 W surge capability - making it preferred for space-constrained automotive and industrial SMT designs requiring zero rework risk and full traceability.

FAQ
What is the clamping voltage of P4SMA200AHE3/5A at its rated peak pulse current?
The clamping voltage (VC) of P4SMA200AHE3/5A is 274 V measured at 1.1 A peak pulse current (IPPM) under the standard 10/1000 µs waveform condition. This value represents the maximum voltage imposed on the protected circuit during a surge event and is confirmed in the Vishay P4SMA datasheet revision 09-Jan-2024, page 2. The P4SMA200AHE3/5A maintains this clamping performance across its specified operating temperature range.
Is P4SMA200AHE3/5A qualified for automotive applications?
Yes, P4SMA200AHE3/5A is AEC-Q101 qualified, as indicated by the "HE3" suffix in its part number and confirmed in the Vishay P4SMA datasheet section "MECHANICAL DATA". It has undergone stress testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC-Q101 Rev D, making it suitable for automotive subsystems such as body control modules and sensor interfaces. The P4SMA200AHE3/5A meets these requirements without derating in standard mounting conditions.
What does the "/5A" suffix mean in P4SMA200AHE3/5A?
The "/5A" suffix denotes the packaging configuration: 13-inch diameter plastic tape and reel containing 7500 units. This is distinct from "/61", which indicates a 7-inch reel with 1800 units. The "/5A" format supports high-volume SMT assembly lines requiring extended reel life and reduced changeover frequency. All electrical and mechanical specifications of P4SMA200AHE3/5A remain identical regardless of reel size.
Can P4SMA200AHE3/5A be used in bidirectional configurations?
No, P4SMA200AHE3/5A is a unidirectional TVS diode, as confirmed by its "A" suffix and absence of "CA" in the part number. Bidirectional variants use the "CA" suffix (e.g., P4SMA200CA). Using P4SMA200AHE3/5A in bidirectional signal paths would result in unintended forward conduction during negative transients. For AC or dual-polarity protection, select the appropriate CA-suffixed variant - P4SMA200AHE3/5A is strictly for DC or single-polarity line protection.
What is the maximum junction temperature rating for P4SMA200AHE3/5A?
The maximum junction temperature (TJ max.) for P4SMA200AHE3/5A is +150 °C, as specified in the "MAXIMUM RATINGS" table of the Vishay P4SMA datasheet (Document Number: 88367, page 1). This rating applies under steady-state and transient conditions and enables reliable operation in under-hood automotive environments and enclosed industrial enclosures. Derating curves in Figure 2 confirm usable power dissipation down to –65 °C ambient.
