Product details
Overview
P4SMA220AHE3/61 from Vishay General Semiconductor is a unidirectional 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 A peak pulse current (IPPM) under 10/1000 µs waveform. It delivers 400 W peak pulse power, features glass passivated junction, AEC-Q101 qualification, and is used to protect MOSFETs and sensor signal lines against inductive switching transients in automotive and industrial control systems.
For engineers reviewing the P4SMA220AHE3/61 datasheet, P4SMA220AHE3/61 pinout, P4SMA220AHE3/61 application, or P4SMA220AHE3/61 equivalent, key selection criteria include clamping voltage (VC = 328 V at IPPM), low leakage (<1.0 µA at VWM), thermal resistance (RθJA = 120 °C/W), and RoHS-compliant AEC-Q101 qualified construction for automotive-grade reliability.
Technical Context
The P4SMA220AHE3/61 operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its 185 V stand-off threshold and fully clamping at 328 V under 328 A transient current. Its glass-passivated silicon junction ensures stable breakdown behavior and fast response time (<1.0 ns), critical for suppressing ESD and lightning-induced surges on DC power rails and sensor interfaces.
Designed for surface-mount assembly on 0.2" × 0.2" copper pads, it supports repetitive surge duty cycles up to 0.01% and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. The cathode band marking enables unambiguous polarity identification during automated placement and inspection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 209 V / 231 V at IT = 1.0 mA - defines precise avalanche initiation range for predictable clamping onset |
| VWM | 185 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 328 V at 328 A (10/1000 µs) - clamped voltage limiting stress on downstream ICs during surge events |
| PPPM | 400 W - peak transient energy absorption capability without failure under standardized surge waveform |
| IFSM | 40 A - single half-sine surge rating (8.3 ms), supporting robustness against power rail faults |
| RθJA | 120 °C/W - thermal resistance from junction to ambient, guiding PCB copper pad sizing for thermal management |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood automotive environments |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, molded plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; polarity indicated by cathode band on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected circuit; conducts during forward surge or bias conditions |
| Cathode | Avalanche clamping terminal | Connected to higher-potential side; initiates reverse breakdown when VRM > VWM, shunting surge current to ground |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS sensor interfaces |
| Glass passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity stress |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving protection margin for 24 V/48 V systems |
| MSL Level 1 (260 °C peak) | Enables compatibility with standard lead-free reflow profiles without preconditioning or baking |
| RoHS-compliant & halogen-free option available | Meets EU RoHS Directive 2011/65/EU and JEDEC JS709E material restrictions for green manufacturing |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamping |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220A | Same VBR range (209–231 V), but SMB package (DO-214AA); 600 W PPPM, higher IPPM (432 A), RθJA = 85 °C/W | Better thermal performance and surge margin; requires larger PCB footprint (4.6 × 3.9 mm vs. 4.3 × 2.6 mm) | Select SMBJ220A when higher surge endurance or improved thermal dissipation is required and board space permits. |
| 1.5KE220A | Through-hole DO-201AE package; identical VBR/VWM/VC specs, but 1500 W PPPM, 5.5 A IFSM, no AEC-Q101 qualification | Higher peak power handling, but incompatible with SMT automation and unsuitable for automotive production | Choose 1.5KE220A only for prototyping or non-automotive legacy designs where through-hole mounting is mandated. |
Compared with SMBJ220A and 1.5KE220A, the P4SMA220AHE3/61 offers optimal balance of AEC-Q101 compliance, compact SMA footprint, and validated 400 W surge capability-making it the preferred choice for volume automotive and industrial SMT production where reliability, size, and process compatibility are jointly critical.

FAQ
What is the clamping voltage of P4SMA220AHE3/61 under maximum rated surge current?
The P4SMA220AHE3/61 has a maximum clamping voltage (VC) of 328 V when subjected to its rated peak pulse current of 328 A using the 10/1000 µs waveform. This value is measured at TA = 25 °C on specified 0.2" × 0.2" copper pads and defines the upper voltage limit imposed on protected circuitry during transient events.
Is P4SMA220AHE3/61 suitable for automotive applications?
Yes, P4SMA220AHE3/61 is AEC-Q101 qualified and manufactured with RoHS-compliant materials, making it suitable for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its +150 °C maximum junction temperature and MSL Level 1 rating support reflow compatibility and under-hood reliability.
What does the "HE3" suffix indicate in P4SMA220AHE3/61?
The "HE3" suffix in P4SMA220AHE3/61 denotes RoHS-compliant construction with AEC-Q101 qualification and packaging in 7" diameter plastic tape and reel (61). It distinguishes this variant from commercial-grade E3/M3 versions and confirms automotive-grade reliability testing and material compliance.
How does the thermal resistance of P4SMA220AHE3/61 affect PCB layout?
The P4SMA220AHE3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W, meaning PCB copper pad area directly impacts steady-state temperature rise. To maintain safe operation at full power, designers must use minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal as specified in the Vishay datasheet for P4SMA220AHE3/61.
Can P4SMA220AHE3/61 be used in bidirectional configurations?
No, P4SMA220AHE3/61 is a unidirectional TVS diode, identified by the "A" suffix and cathode band marking. For bidirectional operation, Vishay specifies part numbers ending in "CA" (e.g., P4SMA220CA), which have symmetrical breakdown characteristics and no polarity marking-P4SMA220AHE3/61 must not be substituted in bidirectional circuits.
