Product details
Overview
P4SMA220CAHE3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in the P4SMA series, designed for clamping voltage transients on signal and power lines. It features a 220 V breakdown voltage (VBR = 209–231 V), 400 W peak pulse power (10/1000 µs), 328 V maximum clamping voltage at rated surge current, and AEC-Q101 qualification for automotive applications - used to protect MOSFETs, sensor interfaces, and communication lines against inductive switching and lightning-induced surges.
For engineers reviewing the P4SMA220CAHE3_A/I datasheet, P4SMA220CAHE3_A/I pinout, P4SMA220CAHE3_A/I application, or P4SMA220CAHE3_A/I equivalent, this page delivers verified electrical parameters, package dimensions, clamping behavior under transient stress, automotive-grade reliability data, and direct alternative options with documented functional trade-offs.
Technical Context
The P4SMA220CAHE3_A/I operates as a bidirectional avalanche diode, symmetrically clamping voltage excursions above ±220 V in either polarity without polarity marking. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for protecting sensitive analog and digital inputs.
Rated for 400 W peak pulse power (10/1000 µs waveform) at TA = 25 °C - derated linearly above 25 °C per Fig. 2 - it sustains repetitive transients at 0.01 % duty cycle and meets MSL Level 1 (260 °C reflow peak). The device exhibits a temperature coefficient of VBR = +0.108 %/°C and operates across –65 °C to +150 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 209 V / 231 V at IT = 1.0 mA - defines precise avalanche onset threshold for bidirectional clamping |
| VWM | 185 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 328 V at 0.91 A - clamped voltage during full-rated 10/1000 µs surge, limiting downstream stress |
| PPPM | 400 W - peak transient energy absorption capability with standard lightning/surge waveform |
| IPPM | 0.91 A - peak surge current corresponding to 400 W into 328 V clamping level |
| TJmax | +150 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| AEC-Q101 | Qualified - validated for automotive electronics per stress test requirements (HTOL, TC, HAST, etc.) |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. No polarity marking - bidirectional symmetry confirmed per datasheet note: "no marking on bidirectional types".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path (bidirectional) | Common terminal for symmetrical clamping; connects to protected line or ground reference |
| Cathode | Transient return path (bidirectional) | Electrically identical to Anode; no functional distinction - device operates identically in both directions |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| 400 W peak pulse power (10/1000 µs) | Withstands IEC 61000-4-5 Level 4 surge events (4 kV/2 Ω) on 50 Ω source impedance lines |
| AEC-Q101 qualification | Validated for automotive powertrain, body control, and ADAS modules requiring long-term reliability |
| MSL Level 1 (260 °C) | Compatible with standard lead-free reflow profiles without preconditioning or baking |
| Glass passivated junction | Ensures stable VBR over time and temperature, minimizing drift in critical protection thresholds |
Applications
| Automotive Sensor Interface Protection | Industrial CAN Bus Line Protection |
|---|---|
|
Use Scenario: Protecting LIN/CAN transceiver inputs and sensor supply rails in engine control units exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional TVS placed between signal line and chassis ground to clamp transients before they reach transceiver ESD structures. Use Value: Prevents latch-up or permanent damage to ISO 11898-compliant transceivers during 12 V system load dump (ISO 7637-2 Pulse 5a). |
Use Scenario: Safeguarding differential CAN_H/CAN_L pair in factory automation controllers subjected to motor drive noise and relay switching spikes. IC Role / Device Role / Timing Role: Common-mode TVS connected across CAN_H–CAN_L and referenced to ground to suppress common-mode surges. Use Value: Maintains bus integrity by limiting differential voltage excursion to <328 V, preserving bit error rate below 10−12 under repeated 1 kV/500 Ω surge stress. |
| Telecom Power Supply Input Clamping | Consumer Audio Signal Line Surge Suppression |
|
Use Scenario: Front-end protection of 48 V PoE-powered telecom equipment against lightning-induced surges on DC input lines. IC Role / Device Role / Timing Role: Primary clamping device placed after input fuse and before DC-DC converter, absorbing bulk surge energy. Use Value: Limits input voltage to ≤328 V during 10/1000 µs transients, preventing overvoltage shutdown or MOSFET avalanche failure in primary-side FETs. |
Use Scenario: Shielding analog audio inputs (e.g., RCA, 3.5 mm jack) in smart speakers from ESD and cable-borne transients. IC Role / Device Role / Timing Role: Low-capacitance TVS (CJ ≈ 30 pF typical at VWM) shunted across line-to-ground to divert sub-100 ns ESD events. Use Value: Clamps human-body-model (HBM) ESD >15 kV without signal distortion, preserving audio fidelity up to 20 kHz bandwidth. |
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 VBR range (209–231 V), but SMB package (DO-214AA); 600 W PPPM, higher IPPM (1.3 A), larger footprint | Higher surge margin suits industrial power supplies; not drop-in due to different pad layout and thermal mass | Select when board space allows larger package and higher single-pulse robustness is required |
| 1.5KE220CA | Through-hole DO-201 package; same VBR/VC; 1500 W PPPM, 5.2 A IPPM; no AEC-Q101 qualification | Used in legacy designs or high-energy surge zones (e.g., AC mains entry); lacks automotive qualification and SMT compatibility | Choose only for non-automotive, through-hole assembly where PCB real estate and reflow constraints are absent |
Compared with P4SMA220CAHE3_A/I, SMBJ220CA offers higher surge capacity but requires PCB redesign, while 1.5KE220CA provides greater energy handling in through-hole form but forfeits AEC-Q101 compliance and surface-mount process compatibility.

FAQ
What is the exact breakdown voltage range for P4SMA220CAHE3_A/I?
The P4SMA220CAHE3_A/I has a guaranteed breakdown voltage (VBR) range of 209 V to 231 V at a test current of 1.0 mA, measured per ANSI/IEEE C62.35. This bidirectional specification applies equally in both polarities and is confirmed in the Electrical Characteristics table on page 2 of Vishay document 88367.
Is P4SMA220CAHE3_A/I suitable for automotive applications?
Yes, P4SMA220CAHE3_A/I is AEC-Q101 qualified (as indicated by the "HE3" suffix and footnote "(1) _A is available for P4SMA6.8(C)A to P4SMA220(C)A, AEC-Q101 qualified"). It is rated for –65 °C to +150 °C operating junction temperature and validated for automotive stress tests including HTOL, temperature cycling, and HAST.
What does the "CA" suffix mean in P4SMA220CAHE3_A/I?
The "CA" suffix in P4SMA220CAHE3_A/I denotes a bidirectional configuration - meaning the device clamps voltage transients symmetrically in both directions. Unlike unidirectional variants (e.g., P4SMA220A), it has no cathode band marking and is electrically identical between its two terminals.
What is the maximum clamping voltage of P4SMA220CAHE3_A/I under surge conditions?
The maximum clamping voltage (VC) of P4SMA220CAHE3_A/I is 328 V at its rated peak pulse current (IPPM) of 0.91 A, tested with a 10/1000 µs waveform. This value ensures downstream ICs see limited overvoltage during standardized surge events such as IEC 61000-4-5.
Does P4SMA220CAHE3_A/I require special PCB layout considerations?
Yes - P4SMA220CAHE3_A/I must be mounted on minimum recommended copper pads (0.2" × 0.2" / 5.0 mm × 5.0 mm per terminal) to achieve its rated 400 W peak pulse power. Smaller pads reduce thermal dissipation and cause premature failure; layout must also minimize trace inductance between the TVS and protected node.
