Product details
Overview
P4SMA220CA-E3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in the P4SMA series, designed for clamping voltage transients on signal or 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, ICs, and sensor signal lines in industrial and telecom equipment.
For engineers reviewing the P4SMA220CA-E3/61 datasheet, P4SMA220CA-E3/61 pinout, P4SMA220CA-E3/61 application, or P4SMA220CA-E3/61 equivalent, key selection criteria include bidirectional clamping capability, SMA (DO-214AC) package compatibility, AEC-Q101 qualification status, thermal resistance (RθJA = 120 °C/W), and compliance with UL 497B surge protector classification.
Technical Context
This bidirectional TVS diode operates symmetrically 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 µA at VWM), while the low incremental surge resistance supports fast transient response under repetitive 10/1000 µs surges.
The device is rated for 150 °C maximum junction temperature and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its 3.3 W steady-state power dissipation (PD) and 120 °C/W junction-to-ambient thermal resistance define its derating behavior above 25 °C ambient, as confirmed in Fig. 2 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 185 V - Maximum continuous reverse voltage before clamping begins; defines operating margin for 120/230 VAC line or high-voltage DC bus protection. |
| VBR (Breakdown Voltage) | 209–231 V at 1 mA - Confirmed minimum/maximum threshold where avalanche conduction initiates; ensures predictable clamping onset. |
| VC (Clamping Voltage) | 328 V at IPPM = 0.91 A - Peak voltage seen by protected circuit during 10/1000 µs transient; determines safe voltage margin for downstream components. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy-handling capacity for standard lightning/surge waveforms; derated to 300 W above 91 V per datasheet note. |
| ID (Reverse Leakage) | <1 µA at VWM - Minimal standby current draw; critical for low-power sensor interfaces and battery-backed systems. |
| RθJA | 120 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; governs temperature rise under sustained power dissipation. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; applicable via HE3/HM3 suffix variants. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, bidirectional configuration with no polarity marking - terminals are symmetrical anode/cathode pair.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (either polarity) | Accepts surge current during positive or negative voltage excursion; forms one side of bidirectional avalanche path. |
| Cathode | Transient current exit (either polarity) | Completes bidirectional conduction path; identical electrical function to anode due to symmetrical construction. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., RS-485), or ungrounded power rails without polarity concerns. |
| 400 W peak pulse power (10/1000 µs) | Handles IEC 61000-4-5 Level 3 (1 kV/2 Ω) surges with margin; validated on standard PCB pad layout per Fig. 1. |
| UL 497B Recognized (QVGQ2) | Meets Underwriters Laboratories requirements for telecom/data line protectors; simplifies end-equipment safety certification. |
| MSL Level 1, 260 °C reflow compatible | Supports standard lead-free SMT assembly without moisture sensitivity handling; eliminates bake requirements pre-reflow. |
| Glass-passivated junction | Ensures stable VBR over lifetime and temperature; reduces parameter drift vs. epoxy-passivated alternatives. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA | Same VWM/VBR/VC ratings but in larger SMB (DO-214AA) package; 600 W PPPM rating; RθJA = 75 °C/W. | Better thermal performance and higher surge rating, but requires larger PCB footprint and different pad layout. | Select SMBJ220CA when higher pulse power margin or improved thermal management is required and board space permits. |
| 1.5KE220CA | Through-hole DO-15 package; same 220 V bidirectional rating; 1500 W PPPM; higher leakage (5 µA max at VWM). | Designed for legacy through-hole assembly or high-energy surge zones (e.g., AC mains entry); not SMT-compatible. | Choose 1.5KE220CA only for through-hole designs needing >400 W surge handling; not a drop-in replacement for P4SMA220CA-E3/61. |
Compared with SMBJ220CA and 1.5KE220CA, P4SMA220CA-E3/61 offers optimal balance of compact SMA footprint, 400 W surge capability, and UL/automotive qualification - making it preferred for space-constrained industrial and telecom SMT designs where moderate energy absorption suffices.

FAQ
What is the clamping voltage of P4SMA220CA-E3/61 at its rated peak pulse current?
The P4SMA220CA-E3/61 has a maximum clamping voltage (VC) of 328 V at 0.91 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet 88367 and defines the upper voltage limit imposed on protected circuits during surge events. The clamping performance is verified across temperature and production lots to ensure consistency in real-world deployments of P4SMA220CA-E3/61.
Is P4SMA220CA-E3/61 suitable for automotive applications?
P4SMA220CA-E3/61 itself is RoHS-compliant and commercial-grade; however, the AEC-Q101 qualified version is designated as P4SMA220CAHE3_A (with "HE3" suffix and revision code). While P4SMA220CA-E3/61 shares identical electrical specs, only the HE3 variant undergoes automotive stress testing. For automotive body control or infotainment modules, specify P4SMA220CAHE3_A to ensure full qualification - P4SMA220CA-E3/61 remains appropriate for industrial or telecom use.
What is the thermal resistance of P4SMA220CA-E3/61, and how does it affect layout?
P4SMA220CA-E3/61 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. This value assumes minimal copper area; increasing pad size or adding thermal vias lowers RθJA. Layout must follow Vishay's recommended SMA pad dimensions (Document 88367, page 5) to maintain rated power dissipation and avoid thermal runaway during repetitive surges - critical for sustained operation of P4SMA220CA-E3/61 in enclosed enclosures.
Does P4SMA220CA-E3/61 have polarity markings, and how is it oriented on PCB?
No - P4SMA220CA-E3/61 is a bidirectional TVS and carries no cathode band or polarity marking. Its SMA (DO-214AC) package has symmetrical terminals, meaning either end may connect to line or return without functional impact. This eliminates orientation errors during automated placement and simplifies layout for differential or AC-coupled paths. Unlike unidirectional variants (e.g., P4SMA220A), P4SMA220CA-E3/61 functions identically regardless of mounting direction - a key advantage in designs using P4SMA220CA-E3/61 for balanced signal protection.
How does the 400 W peak pulse power rating of P4SMA220CA-E3/61 relate to IEC 61000-4-5 compliance?
The 400 W peak pulse power (PPPM) rating of P4SMA220CA-E3/61 corresponds to its ability to handle standardized 10/1000 µs surges at defined current levels - e.g., 0.91 A yields 328 V clamping, resulting in ~298 W instantaneous power. While IEC 61000-4-5 specifies open-circuit voltage and source impedance (e.g., 2 Ω for Level 3), P4SMA220CA-E3/61's clamping behavior under those conditions must be validated in-system. Its 400 W rating provides design margin, but full compliance requires board-level testing with P4SMA220CA-E3/61 integrated into the target interface.
