Product details
Overview
P4SMA220A-E3/5A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 220 V standoff voltage (VWM), 209–231 V breakdown voltage (VBR) at 1 mA, 328 A peak pulse current (IPPM), 300 W peak pulse power (PPPM), and clamps to 328 V under 10/1000 µs surge - deployed in industrial sensor interfaces and DC power rails.
For engineers reviewing the P4SMA220A-E3/5A datasheet, P4SMA220A-E3/5A pinout, P4SMA220A-E3/5A application, or P4SMA220A-E3/5A equivalent, this page delivers verified electrical parameters, package dimensions, clamping behavior under transient stress, thermal derating curves, and AEC-Q101-qualified alternatives for automotive-grade design-in.
Technical Context
The P4SMA220A-E3/5A operates as a unidirectional avalanche diode with glass-passivated junction, optimized for fast response (<1 ns) to ESD and lightning-induced transients. Its low incremental surge resistance ensures stable clamping during repetitive 10/1000 µs surges at 0.01% duty cycle.
Rated for TJ = –65 °C to +150 °C, it uses SMA (DO-214AC) packaging with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. Polarity is marked by a cathode band; no marking on bidirectional variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 185 V - Maximum continuous reverse voltage before conduction begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 209–231 V at IT = 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 328 V at IPPM = 328 A - Measured peak voltage across device during 10/1000 µs surge; determines protected circuit's maximum stress level. |
| PPPM (Peak Pulse Power) | 300 W - Sustained surge energy handling capability above 91 V per 10/1000 µs waveform; derates linearly above TA = 25 °C. |
| ID (Reverse Leakage) | 1.0 µA max at VWM = 185 V - Minimal standby current leakage; preserves efficiency in high-impedance bias networks. |
| RθJA | 120 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; informs PCB thermal layout requirements. |
| TJ max | +150 °C - Maximum allowable junction temperature; sets upper limit for ambient + self-heating in continuous operation. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile case with molded UL 94 V-0 compound and cathode band marking for unidirectional polarity.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220A-E3/52 (Vishay) | Same VWM/VBR/VC specs but SMB (DO-214AA) package; 50% larger footprint, 10% higher RθJA (130 °C/W). | Better suited for manual repair or high-power derating scenarios where board space allows larger pad area. | Select when thermal margin is constrained and PCB real estate permits 2.5 mm × 4.5 mm footprint instead of 2.5 mm × 4.0 mm. |
| 1.5SMC220A (ON Semiconductor) | Identical electrical specs (VWM = 185 V, VC = 328 V), same SMA package, but rated for 400 W PPPM (not derated) and lacks AEC-Q101 qualification. | Acceptable for commercial/industrial use but not validated for automotive underhood environments. | Choose for cost-sensitive non-automotive designs requiring full 400 W rating at 25 °C without derating above 91 V. |
Compared with P4SMA220A-E3/5A, SMBJ220A-E3/52 trades compactness for improved thermal dissipation in space-tolerant layouts, while 1.5SMC220A offers identical clamping performance without automotive qualification - making P4SMA220A-E3/5A the optimal choice for AEC-Q101-compliant, space-constrained industrial and automotive applications.

FAQ
What is the clamping voltage of P4SMA220A-E3/5A under a 10/1000 µs surge?
The P4SMA220A-E3/5A clamps to a maximum of 328 V when subjected to its rated peak pulse current of 328 A using the standardized 10/1000 µs waveform. This value is measured at the device terminals under specified test conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads) and represents the highest voltage seen by downstream circuitry during surge events.
Is P4SMA220A-E3/5A suitable for automotive applications?
The base P4SMA220A-E3/5A is RoHS-compliant and commercial-grade. For automotive use, Vishay offers the AEC-Q101-qualified variant P4SMA220AHE3_A (with HE3 suffix and revision code A). That part undergoes extended reliability testing including HTOL, temperature cycling, and ESD per AEC-Q101, whereas P4SMA220A-E3/5A itself is not qualified.
What is the maximum reverse leakage current of P4SMA220A-E3/5A at its standoff voltage?
At its maximum standoff voltage of 185 V and TA = 25 °C, the P4SMA220A-E3/5A exhibits a maximum reverse leakage current (ID) of 1.0 µA. This low leakage preserves signal integrity in high-impedance sensing paths and minimizes power loss in always-on DC systems.
Does P4SMA220A-E3/5A have a bidirectional version?
No - P4SMA220A-E3/5A is strictly unidirectional, indicated by the "A" suffix. Bidirectional variants use the "CA" suffix (e.g., P4SMA220CA). The "A" denotes unidirectional construction with cathode band marking; "CA" devices lack polarity marking and conduct symmetrically in both directions.
What is the thermal resistance junction-to-ambient for P4SMA220A-E3/5A?
The P4SMA220A-E3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on the minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes still air conditions and is used to calculate allowable power dissipation at elevated ambient temperatures.
