Product details
Overview
P4SMA220CA-E3/5A from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, rated for 220 V breakdown voltage (VBR = 209–231 V at IT = 1.0 mA), 185 V stand-off voltage (VWM), and 328 V maximum clamping voltage (VC) at 0.91 A peak pulse current (IPPM). It delivers 400 W peak pulse power (10/1000 µs waveform) and is used to protect signal lines and power rails in industrial sensor interfaces against ESD and inductive switching transients.
For engineers reviewing the P4SMA220CA-E3/5A datasheet, P4SMA220CA-E3/5A pinout, P4SMA220CA-E3/5A application, or P4SMA220CA-E3/5A equivalent, this page provides verified electrical parameters, bidirectional clamping behavior, thermal resistance (RθJA = 120 °C/W), AEC-Q101 qualification status, and RoHS-compliant packaging details for robust overvoltage protection design.
Technical Context
The P4SMA220CA-E3/5A operates as a bidirectional avalanche diode with symmetrical clamping in both polarities, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM).
Designed for transient suppression per IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT), it exhibits fast response time (<1.0 ns), low incremental surge resistance, and meets MSL Level 1 (260 °C reflow). Junction temperature range spans –65 °C to +150 °C, with derating above 25 °C per Fig. 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 209 V / 231 V at IT = 1.0 mA - defines reliable avalanche initiation threshold under test conditions |
| VWM | 185 V - maximum continuous reverse working voltage before significant leakage begins |
| VC @ IPPM | 328 V at IPPM = 0.91 A (10/1000 µs) - clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 400 W - peak transient power handling capability under standard 10/1000 µs waveform |
| IPPM | 0.91 A - maximum non-repetitive surge current the device can safely clamp |
| RθJA | 120 °C/W - thermal resistance from junction to ambient, critical for PCB pad layout and power derating |
| TJ max | +150 °C - maximum allowable junction temperature, limiting sustained power dissipation |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. No polarity marking on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; one side of symmetrical avalanche junction | Connected to line being protected; forms bidirectional conduction path with cathode |
| Cathode | Current exit terminal in forward bias; second side of symmetrical avalanche junction | Connected to reference (e.g., ground or return); completes clamping loop during either polarity surge |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC, differential, or floating signal lines without polarity sensitivity |
| 400 W peak pulse power (10/1000 µs) | Supports robust immunity against IEC 61000-4-4 EFT bursts and inductive load switch-offs |
| MSL Level 1, 260 °C peak reflow | Compatible with standard lead-free SMT assembly processes without moisture sensitivity concerns |
| AEC-Q101 qualified (P4SMA220CA-E3/5A variant not AEC-Q101; base P/NHE3_X is) | This specific part (E3/5A) is commercial-grade; automotive-grade versions use HE3/HM3 suffixes |
| Glass passivated junction | Ensures stable VBR tolerance, low leakage (<1 µA), and long-term reliability under thermal cycling |
Applications
| Industrial Sensor Signal Protection | Telecom Line Interface |
|---|---|
|
Use Scenario: Protecting 4–20 mA analog output lines in factory automation sensors exposed to motor drive noise and relay switching transients. IC Role / Device Role / Timing Role: Bidirectional TVS placed across signal and return lines to clamp ±kV-level surges before they reach ADC or isolator inputs. Use Value: Limits induced voltage to ≤328 V during 0.91 A transients, preserving signal integrity and preventing damage to downstream op-amps or microcontrollers. |
Use Scenario: Safeguarding RS-485 transceiver I/O pins in building management systems connected to long outdoor cable runs. IC Role / Device Role / Timing Role: Fast-response TVS mounted at connector entry point to absorb lightning-induced surges and ESD events on differential bus lines. Use Value: Clamps transients within <1 ns while maintaining low capacitance (<50 pF typical), avoiding data corruption at up to 10 Mbps. |
| Consumer Power Adapter Input | Automotive Body Control Module |
|
Use Scenario: Secondary-side overvoltage protection in USB-C PD adapters where 24 V auxiliary rails may experience load dump or coupling from primary side. IC Role / Device Role / Timing Role: Standoff-rated TVS (VWM = 185 V) placed across DC output to suppress ringing and cross-regulation spikes. Use Value: Withstands continuous 185 V operation while clamping 400 W surges-critical for UL 497B-compliant surge protector recognition. |
Use Scenario: Protecting LIN bus nodes in door module ECUs from battery transients and jump-start voltage spikes. IC Role / Device Role / Timing Role: Bidirectional TVS selected for VWM > 14 V system nominal and VC < 35 V to avoid interfering with LIN physical layer signaling. Use Value: Though P4SMA220CA-E3/5A is commercial-grade, its 220 V rating allows reuse in pre-qualification prototypes; AEC-Q101 variants (e.g., P4SMA220CAHE3_A) are production-ready. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA | Same VBR/VWM/VC, but SMB package (DO-214AA); higher IPPM = 1.3 A, lower RθJA = 80 °C/W | Higher power handling and better thermal performance; requires larger PCB footprint | Select when surge current exceeds 0.91 A or board layout allows SMB size |
| 1.5KE220CA | Through-hole TO-218; same VBR, but PPPM = 1500 W, IPPM = 4.5 A, VC = 306 V | Higher ruggedness for mains-connected equipment; incompatible with SMT-only assembly | Choose for high-energy AC line protection where automated placement is not required |
Compared with P4SMA220CA-E3/5A, SMBJ220CA offers superior thermal dissipation and surge margin in compact SMT form, while 1.5KE220CA provides significantly higher energy absorption at the cost of through-hole mounting and larger volume-making each suitable for distinct mechanical and reliability requirements.

FAQ
What is the breakdown voltage tolerance for P4SMA220CA-E3/5A?
The P4SMA220CA-E3/5A has a specified breakdown voltage range of 209 V to 231 V at test current IT = 1.0 mA, representing ±5 % tolerance around the nominal 220 V rating. This tolerance is confirmed in the Electrical Characteristics table on page 2 of Vishay document 88367 and applies to both directions due to its bidirectional construction.
Is P4SMA220CA-E3/5A AEC-Q101 qualified?
No, P4SMA220CA-E3/5A is a commercial-grade part with RoHS compliance (E3 suffix) and halogen-free option (M3 suffix). AEC-Q101 qualification is available only on variants with HE3 or HM3 suffixes (e.g., P4SMA220CAHE3_A), which include additional stress testing and traceability for automotive use.
What is the maximum clamping voltage of P4SMA220CA-E3/5A under surge conditions?
The maximum clamping voltage (VC) of P4SMA220CA-E3/5A is 328 V, measured at peak pulse current IPPM = 0.91 A using the standardized 10/1000 µs double-exponential waveform. This value ensures protected circuits remain below critical overvoltage thresholds during transient events.
Can P4SMA220CA-E3/5A be used in AC signal line protection?
Yes, P4SMA220CA-E3/5A is explicitly designed for bidirectional applications and is ideal for AC-coupled or differential signal lines such as RS-485, CAN, or audio interfaces. Its symmetrical VBR and VC characteristics ensure equal clamping performance regardless of voltage polarity.
What is the thermal resistance of P4SMA220CA-E3/5A, and how does it affect layout?
P4SMA220CA-E3/5A has a typical junction-to-ambient thermal resistance RθJA of 120 °C/W when mounted on minimum recommended copper pads (0.2" × 0.2"). To maintain safe junction temperatures under repetitive surges, designers must provide adequate copper area and consider derating per Figure 2 in the datasheet-especially above 25 °C ambient.
