Product details
Overview
P4SMA220A-M3/5A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 220 V standoff voltage (VWM), 209–231 V breakdown voltage (VBR) at 1 mA, 328 A peak pulse current (IPPM), and clamps transients to ≤328 V under 10/1000 µs waveform - deployed in industrial sensor interfaces and DC power rails.
For engineers reviewing the P4SMA220A-M3/5A datasheet, P4SMA220A-M3/5A pinout, P4SMA220A-M3/5A application, or P4SMA220A-M3/5A equivalent, this page delivers verified electrical parameters, package dimensions, thermal derating behavior, clamping performance, and AEC-Q101-qualified alternatives for automotive-grade surge protection design.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, optimized for fast transient suppression on DC supply lines and low-speed signal paths. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and low incremental surge resistance, enabling consistent clamping during repetitive 10/1000 µs surges up to 400 W (derated to 300 W above 91 V).
Thermal performance is defined by RθJA = 120 °C/W and RθJL = 30 °C/W, requiring minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for rated PPPM. The device meets MSL Level 1 (260 °C peak reflow) and supports automated SMT placement in commercial and automotive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 185 V - maximum continuous reverse operating voltage before conduction begins; defines safe DC bias margin. |
| VBR (Breakdown Voltage) | 209–231 V at IT = 1 mA - precise voltage threshold where avalanche conduction initiates reliably. |
| VC (Clamping Voltage) | 328 V at IPPM = 0.91 A - peak voltage seen across protected circuit during full-rated 10/1000 µs transient. |
| PPPM (Peak Pulse Power) | 400 W - maximum single-pulse energy handling capability under standard 10/1000 µs waveform. |
| ID (Reverse Leakage) | ≤1.0 µA at VWM - minimal standby current ensuring negligible power loss in high-impedance circuits. |
| TJ max | 150 °C - maximum junction temperature defining operational limits and PCB thermal layout requirements. |
| Package | SMA (DO-214AC) - industry-standard surface-mount outline with 2.54 mm lead pitch and 5.28 mm body length. |
Pinout & Package
Package: SMA (DO-214AC), molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Cathode indicated by band on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or reference node; completes conduction path during reverse-biased transient events. |
| Cathode | High-side connection point | Connected to protected line; avalanche conduction occurs when voltage exceeds VBR relative to anode. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 µs) | Enables protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on 24–48 V DC systems without derating. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., inductive switch-off), improving system immunity. |
| AEC-Q101 qualified (M3 suffix) | Validated for automotive under-hood and infotainment applications with extended temperature cycling and humidity testing. |
| Halogen-free & RoHS-compliant | Meets EU Directive 2011/65/EU and JEDEC J-STD-20 MSL Level 1, supporting green manufacturing and reflow compatibility. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ220A | Same VWM (185 V), identical SMA package, but lower PPPM (400 W vs. P4SMA220A-M3/5A's 400 W); slightly higher VC (339 V vs. 328 V). | Marginally reduced clamping performance; suitable where tighter voltage tolerance is not critical. | Select SMAJ220A if legacy design uses SMAJ series and board layout is fixed; verify clamping margin against protected IC's absolute max rating. |
| 1.5SMC220A | Higher power rating (1500 W), DO-214AB package (larger footprint), same VWM/VBR range; RθJA ≈ 30 °C/W vs. 120 °C/W. | Requires larger PCB area and heatsinking; suited for high-energy surge environments (e.g., outdoor telecom). | Choose 1.5SMC220A only when system-level surge tests exceed IEC 61000-4-5 Level 4; avoid for space-constrained consumer designs. |
Compared with SMAJ220A, P4SMA220A-M3/5A offers superior clamping (328 V vs. 339 V) and halogen-free compliance; versus 1.5SMC220A, it provides compact SMT fit with lower thermal resistance to ambient but reduced single-pulse energy capacity.

FAQ
What is the clamping voltage of P4SMA220A-M3/5A under maximum rated surge current?
The P4SMA220A-M3/5A clamps to a maximum of 328 V when subjected to its rated peak pulse current of 0.91 A under the standard 10/1000 µs waveform. This value is measured at the device terminals with specified mounting conditions (0.2" × 0.2" copper pads), and represents the upper voltage limit imposed on protected circuitry during transient events. Designers must ensure downstream components tolerate this clamped voltage.
Is P4SMA220A-M3/5A suitable for automotive applications?
Yes, P4SMA220A-M3/5A is AEC-Q101 qualified (as indicated by the M3 suffix) and specifically validated for automotive use including body electronics, infotainment, and power distribution modules. It meets stringent requirements for temperature cycling, humidity resistance, and mechanical shock - making it appropriate for under-hood and cabin-mounted systems operating from −65 °C to +150 °C junction temperature.
What does the "M3" suffix mean in P4SMA220A-M3/5A?
The "M3" suffix in P4SMA220A-M3/5A denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes this variant from the E3 (RoHS-compliant, commercial grade) and HE3/HM3 (automotive-grade with revision coding) versions. The M3 version is intended for automotive and industrial applications requiring both environmental compliance and reliability certification.
How does the thermal resistance of P4SMA220A-M3/5A affect PCB layout?
P4SMA220A-M3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W, which requires careful PCB copper pad design to maintain safe operation. To achieve rated 400 W pulse power, each terminal must be mounted on ≥0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads. Reducing pad size increases junction temperature and necessitates derating per Figure 2 in the datasheet - critical for sustained surge duty cycles.
Can P4SMA220A-M3/5A be used in bidirectional configurations?
No, P4SMA220A-M3/5A is a unidirectional TVS diode, identified by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., P4SMA220CA). Using P4SMA220A-M3/5A in bidirectional signal lines would result in forward conduction during negative transients, causing failure. For AC or dual-polarity protection, select the CA-series part instead.
