Product details
Overview
P4SMA22CA-E3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for clamping voltage transients on signal and power lines. It features a 22 V standoff voltage (VWM), 24.4–26.9 V breakdown voltage (VBR) at 1 mA, 30.6 V maximum clamping voltage (VC) at 13.1 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - used in automotive sensor interfaces, industrial I/O protection, and telecom line surge suppression.
For engineers reviewing the P4SMA22CA-E3/61 datasheet, P4SMA22CA-E3/61 pinout, P4SMA22CA-E3/61 application, or P4SMA22CA-E3/61 equivalent, this device delivers verified bidirectional transient suppression in SMA (DO-214AC) package with AEC-Q101 qualification, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability board-level ESD and lightning surge protection design.
Technical Context
The P4SMA22CA-E3/61 operates as a symmetrical avalanche diode, conducting equally in both directions above its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and fast response time (<1 ns), enabling effective suppression of ESD (IEC 61000-4-2), EFT (IEC 61000-4-4), and lightning-induced surges (IEC 61000-4-5).
Thermally, it exhibits RθJA = 120 °C/W and RθJL = 30 °C/W, supporting operation up to TJ = 150 °C. With 1.0 µA max reverse leakage at VWM, it minimizes standby power loss in always-on circuits while maintaining robust clamping performance under repetitive 0.01% duty-cycle pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 22 V - Maximum continuous reverse voltage before significant conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 24.4–26.9 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients without premature leakage. |
| VC (Clamping Voltage) | 30.6 V at 13.1 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge; enables safe margin for 24 V systems. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capability per transient event; validated on 5.0 mm × 5.0 mm copper pads. |
| IPPM (Peak Pulse Current) | 13.1 A - Maximum non-repetitive surge current handled without degradation; supports IEC 61000-4-5 Level 3 (1 kV/2 Ω). |
| TJmax | 150 °C - Maximum junction temperature; allows reliable operation in under-hood automotive and industrial ambient environments. |
| Package | SMA (DO-214AC) - Standardized surface-mount outline with 2.54 mm lead pitch; compatible with automated pick-and-place and reflow. |
Pinout & Package
SMA (DO-214AC) package: molded epoxy case with matte tin-plated leads, UL 94 V-0 rated, MSL Level 1 (260 °C peak reflow), no polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional terminal pair | No functional polarity - either terminal serves as anode or cathode depending on transient polarity; enables single-device protection of AC or differential lines. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for engine control, ADAS sensors, and infotainment interfaces. |
| 400 W peak pulse power (10/1000 µs) | Enables single-device protection against IEC 61000-4-5 surge events up to 1 kV open-circuit / 0.5 kA short-circuit in 24 V systems. |
| Glass passivated chip junction | Ensures long-term parameter stability and low leakage drift over temperature and lifetime - critical for precision analog front-ends. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns response), reducing stress on downstream ICs like CAN transceivers or ADC drivers. |
| MSL Level 1, 260 °C peak reflow | Eliminates pre-baking requirement and supports standard Pb-free reflow profiles - reduces manufacturing complexity and cost. |
Applications
| Automotive Sensor Interface | Industrial PLC I/O Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22CA | Higher PPPM = 600 W, larger SMB (DO-214AA) package, 33.2 V VC at 17.1 A | Better suited for higher-energy surges (e.g., 4 kV IEC 61000-4-5); requires larger PCB area and different pad layout | Select when surge energy exceeds 400 W or when legacy SMB footprint is mandated. |
| 1.5KE22CA | Through-hole TO-218 package, 400 W rating, 33.2 V VC at 12.1 A, higher parasitic inductance | Used in legacy power supply inputs or high-voltage AC lines where manual assembly or creepage distance is prioritized | Choose only for through-hole designs requiring proven field reliability in mains-connected equipment. |
Compared with SMBJ22CA and 1.5KE22CA, the P4SMA22CA-E3/61 provides optimal balance of 400 W surge capability, ultra-low profile SMA packaging, and AEC-Q101 qualification - making it the preferred choice for space-constrained, automotive-grade, and high-volume surface-mount transient protection.

FAQ
What is the clamping voltage of P4SMA22CA-E3/61 at its rated peak pulse current?
The P4SMA22CA-E3/61 has a maximum clamping voltage (VC) of 30.6 V at 13.1 A peak pulse current with a 10/1000 µs waveform. This value is measured under standardized test conditions on 5.0 mm × 5.0 mm copper pads and represents the highest voltage the protected circuit will experience during a defined surge event. The P4SMA22CA-E3/61 maintains this clamping performance across its specified operating temperature range.
Is P4SMA22CA-E3/61 suitable for automotive applications?
Yes, P4SMA22CA-E3/61 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes a glass-passivated junction, MSL Level 1 reflow compatibility, and validation across temperature cycling, high-temperature reverse bias, and ESD stress tests. The P4SMA22CA-E3/61 is commonly deployed in engine control units, body electronics, and ADAS sensor interfaces where reliability under harsh conditions is mandatory.
Does P4SMA22CA-E3/61 have polarity markings on the package?
No, P4SMA22CA-E3/61 does not have polarity markings because it is a bidirectional TVS diode. Unlike unidirectional variants (e.g., P4SMA22A), the CA suffix indicates symmetrical behavior - both terminals function identically regardless of voltage polarity. This eliminates orientation concerns during placement and simplifies layout for AC-coupled or differential signal paths.
What is the maximum reverse leakage current for P4SMA22CA-E3/61 at its standoff voltage?
The P4SMA22CA-E3/61 exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 22 V standoff voltage (VWM) and 25 °C ambient temperature. This low leakage ensures minimal power drain in always-on circuits and preserves signal integrity in high-impedance analog sensing paths. The P4SMA22CA-E3/61 maintains leakage below 5 µA up to 85 °C per Vishay's characterization data.
Can P4SMA22CA-E3/61 be used in place of unidirectional TVS diodes?
No - P4SMA22CA-E3/61 is strictly bidirectional and must not replace unidirectional TVS diodes (e.g., P4SMA22A) in DC-biased circuits where forward conduction would cause malfunction. Its symmetrical structure conducts in both directions above VBR, making it ideal for AC lines, differential buses, or floating references. Using P4SMA22CA-E3/61 in a unidirectional application risks unintended conduction during normal operation.
