Product details
Overview
P4SMA220CA-M3/5A from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on signal and power lines. It features a 220 V standoff voltage (VWM), 231 V minimum breakdown voltage (VBR), 328 V maximum clamping voltage (VC) at 0.91 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 µs waveform - used to protect MOSFETs, sensor interfaces, and telecom line drivers against ESD and inductive switching surges.
For engineers reviewing the P4SMA220CA-M3/5A datasheet, P4SMA220CA-M3/5A pinout, P4SMA220CA-M3/5A application, or P4SMA220CA-M3/5A equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, thermal resistance (RθJA = 120 °C/W), AEC-Q101 qualification status, and halogen-free RoHS compliance per M3 suffix - critical for automotive and industrial surge protection design-in.
Technical Context
The P4SMA220CA-M3/5A operates as a symmetrical bidirectional TVS, delivering identical clamping performance in both polarities without polarity marking. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, supporting repetitive transient suppression under 0.01% duty cycle at 400 W (≤91 V) or 300 W (>91 V).
Thermally, it uses a DO-214AC package with RθJL = 30 °C/W and RθJA = 120 °C/W (on 5.0 mm × 5.0 mm copper pads), rated for TJ = -65 °C to +150 °C operation. The M3 suffix confirms halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance and MSL Level 1 reflow profile (260 °C peak).
Key Specifications

Use Value: Maintains signal fidelity below 185 V working voltage while limiting transient excursions to ≤328 V - preventing ADC saturation and op-amp damage. |
Use Scenario: Safeguarding CANH/CANL differential pair in automotive ECUs subjected to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Symmetric clamping device mounted directly at connector entry point to shunt surge energy before reaching transceiver. Use Value: Withstands repetitive 300 W surges at >91 V and operates up to +150 °C - ensuring CAN communication continuity during engine bay thermal stress. |
| Telecom Line Driver Protection | DC Power Rail Surge Suppression |
Use Scenario: Shielding RS-485 transceivers in base station remote radio units from lightning-induced surges on long-haul data lines. IC Role / Device Role / Timing Role: Bidirectional TVS connected between differential lines and ground to suppress common-mode transients exceeding 1 kV. Use Value: 328 V clamping voltage limits stress on 3.3 V or 5 V transceivers when combined with series impedance - avoids destructive latch-up. |
Use Scenario: Guarding 24 V DC input rails of industrial controllers against inductive switching spikes from solenoid valves and contactors. IC Role / Device Role / Timing Role: Parallel-connected TVS across rail-to-ground to absorb 400 W energy bursts without thermal runaway. Use Value: 120 °C/W junction-to-ambient thermal resistance allows stable operation on standard FR-4 with minimal copper area - simplifies heatsinking. |
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 VWM (185 V) and VC (328 V), but SMB package (DO-214AA); 10% larger footprint, RθJA = 100 °C/W. | Better thermal performance but requires PCB redesign; preferred for high-reliability telecom where board space permits. | Select SMBJ220CA only if thermal derating margins are insufficient with SMA's 120 °C/W RθJA. |
| 1.5KE220CA | Through-hole TO-218 package; higher PPPM (1500 W), but slower response (>5 ns) and no AEC-Q101 qualification. | Suitable for non-automotive AC mains or legacy equipment; incompatible with SMT production and automotive qualification requirements. | Choose 1.5KE220CA only for prototyping or repair where through-hole mounting and higher surge rating outweigh SMT and qualification needs. |
Compared with SMBJ220CA and 1.5KE220CA, the P4SMA220CA-M3/5A offers optimal balance of SMT compatibility, AEC-Q101 compliance, and thermal performance in compact DO-214AC - making it the default choice for new automotive and industrial designs requiring validated reliability and automated assembly.

FAQ
What is the clamping voltage of P4SMA220CA-M3/5A at its rated peak pulse current?
The P4SMA220CA-M3/5A has a maximum clamping voltage (VC) of 328 V at a peak pulse current (IPPM) of 0.91 A, measured using the standardized 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events and is confirmed in the Vishay P4SMA Series datasheet (Document Number: 88367, Rev. 09-Jan-2024). The P4SMA220CA-M3/5A maintains this clamping performance bidirectionally.
Is P4SMA220CA-M3/5A qualified for automotive applications?
Yes, the P4SMA220CA-M3/5A is AEC-Q101 qualified, as indicated by the "M3" suffix per Vishay's ordering nomenclature and confirmed in the P4SMA Series datasheet. It meets stress test requirements for temperature cycling, humidity, mechanical shock, and surge immunity required for automotive powertrain and body electronics. The P4SMA220CA-M3/5A is explicitly listed among AEC-Q101 qualified variants in the document's revision notes.
What does the "CA" suffix mean in P4SMA220CA-M3/5A?
The "CA" suffix in P4SMA220CA-M3/5A denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both forward and reverse directions, with identical VWM, VBR, and VC characteristics across polarity. This is distinct from unidirectional "A"-suffix parts, which require correct cathode orientation. The P4SMA220CA-M3/5A has no polarity marking and is used across AC-coupled or differential signal paths.
What is the thermal resistance of P4SMA220CA-M3/5A, and how does it affect PCB layout?
The P4SMA220CA-M3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay datasheet. This value guides copper pour sizing: reducing pad area increases thermal resistance and risks junction overheating during repetitive surges. The P4SMA220CA-M3/5A must be placed with adequate thermal relief to maintain TJ ≤ 150 °C under worst-case duty cycle conditions.
How does the M3 suffix differ from E3 in P4SMA220CA-M3/5A?
The "M3" suffix in P4SMA220CA-M3/5A indicates halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance, whereas "E3" denotes standard RoHS compliance without halogen-free assurance. Both meet UL 94 V-0 and MSL Level 1, but the P4SMA220CA-M3/5A satisfies stricter environmental mandates for automotive and consumer electronics requiring bromine/chlorine restrictions. The M3 variant is fully backward-compatible with E3 in form, fit, and function.
