Product details
Overview
P6SMB220A-M3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 220 V standoff voltage (VWM), 231 V minimum breakdown voltage (VBR), and 328 V maximum clamping voltage (VC) at 1.8 A peak pulse current (IPPM), designed to protect power rails and signal lines in industrial power supplies and automotive ECUs against lightning-induced surges and inductive switching transients.
For engineers reviewing the P6SMB220A-M3/5B datasheet, P6SMB220A-M3/5B pinout, P6SMB220A-M3/5B application, or P6SMB220A-M3/5B equivalent, this device offers halogen-free RoHS-compliant construction, AEC-Q101 qualification (suffix _B), 600 W peak pulse power handling with 10/1000 μs waveform, and low incremental surge resistance for robust overvoltage protection in space-constrained PCB layouts.
Technical Context
The P6SMB220A-M3/5B operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its 209–231 V breakdown range (tested at 1 mA), clamping transient energy within 1 ns response time while maintaining 185 V maximum reverse leakage (ID) at VWM. Its glass-passivated junction ensures stable performance across -65 °C to +150 °C operating temperature range.
Thermally, it exhibits 100 °C/W junction-to-ambient thermal resistance (RθJA) on standard 0.2" × 0.2" copper pads and supports repetitive 0.01% duty cycle pulses. The cathode band marking enables unambiguous polarity identification during automated placement, critical for correct orientation in DC-biased protection circuits.
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 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on under surge conditions. |
| VC (Clamping Voltage) | 328 V at IPPM = 1.8 A - Peak voltage seen by protected circuit during 10/1000 μs transient; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 600 W - Sustained surge energy absorption capability per 10/1000 μs waveform; validates protection level for IEC 61000-4-5 Level 4. |
| ID (Reverse Leakage) | 1.0 μA at VWM - Ultra-low leakage preserves system efficiency and prevents false triggering in high-impedance nodes. |
| TJ max. | +150 °C - Enables reliable operation in under-hood automotive and industrial environments without derating. |
| Package | SMB (DO-214AA) - Low-profile surface-mount outline (4.57 mm × 3.94 mm) compatible with standard reflow profiles and J-STD-020 MSL Level 1. |

Use Scenario: Suppressing flyback voltage spikes generated by brushed DC motors in smart home appliances (e.g., vacuum cleaners, power tools). IC Role / Device Role / Timing Role: Parallel-connected TVS across motor terminals, diverting inductive energy away from H-bridge MOSFETs. Use Value: Extends MOSFET lifetime by capping drain-source voltage to 328 V during commutation, preventing avalanche overstress. |
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-E3/5B | Same VWM/VBR/VC specs but SMA package (smaller footprint, higher RθJA = 140 °C/W); 400 W PPPM rating. | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 due to reduced power handling. | Select when board space is constrained and surge threat level is ≤400 W. |
| 1.5SMC220A | Same electrical specs but SMC (DO-214AB) package; 1000 W PPPM rating; larger footprint (7.11 mm × 6.22 mm). | Supports higher-duty-cycle surges and better thermal dissipation; requires more PCB area. | Choose for mission-critical industrial systems requiring margin beyond 600 W or extended thermal endurance. |
Compared with SMAJ220A-E3/5B and 1.5SMC220A, the P6SMB220A-M3/5B delivers optimal balance of 600 W surge capacity, SMB footprint compatibility, and halogen-free AEC-Q101 qualification-making it ideal for automotive and industrial designs where reliability, regulatory compliance, and layout density are jointly prioritized.

FAQ
What is the clamping voltage of the P6SMB220A-M3/5B at its rated peak pulse current?
The P6SMB220A-M3/5B has a maximum clamping voltage (VC) of 328 V at its specified peak pulse current (IPPM) of 1.8 A under a 10/1000 μs waveform. This value is measured per Figure 1 in the official Vishay datasheet (Document Number: 88370), and defines the upper voltage limit imposed on protected circuitry during surge events. Engineers must verify that downstream components tolerate ≤328 V to ensure robust system-level protection using the P6SMB220A-M3/5B.
Is the P6SMB220A-M3/5B suitable for automotive applications?
Yes, the P6SMB220A-M3/5B is AEC-Q101 qualified when ordered with the "_B" suffix (e.g., P6SMB220A-M3/5B corresponds to the _B variant per Vishay's ordering note on page 3). It meets automotive reliability requirements for temperature cycling, humidity resistance, and surge endurance, making it appropriate for use in engine control units, body control modules, and infotainment power rails where the P6SMB220A-M3/5B provides validated transient suppression.
What does the "M3" suffix indicate in P6SMB220A-M3/5B?
The "M3" suffix in P6SMB220A-M3/5B denotes halogen-free, RoHS-compliant construction per Vishay's material categorization standards (Document Number: 99912). Unlike the "E3" suffix (RoHS-compliant but not halogen-free), M3 ensures brominated flame retardants are excluded from the molding compound-critical for compliance with EU environmental directives and certain OEM sustainability requirements for the P6SMB220A-M3/5B.
How does the P6SMB220A-M3/5B compare to bidirectional TVS diodes?
The P6SMB220A-M3/5B is unidirectional and intended for DC-biased protection paths, such as positive power rails referenced to ground. Bidirectional variants (e.g., P6SMB220CA) are used in AC or floating signal lines like RS-485 or USB. Using the P6SMB220A-M3/5B in AC applications would cause forward conduction during negative half-cycles, so correct polarity alignment is essential-its cathode band must face the higher-potential node in all designs utilizing the P6SMB220A-M3/5B.
What is the thermal resistance of the P6SMB220A-M3/5B, and how does it affect layout?
The P6SMB220A-M3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °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 assumes minimal copper area; increasing pad size or adding thermal vias lowers RθJA and improves surge survivability. Layouts for the P6SMB220A-M3/5B must allocate adequate copper to sustain repeated 600 W pulses without exceeding +150 °C junction temperature.
