Product details
Overview
P6SMB220A-M3/52 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-M3/52 datasheet, P6SMB220A-M3/52 pinout, P6SMB220A-M3/52 application, or P6SMB220A-M3/52 equivalent, this part delivers verified 600 W peak pulse power handling with 10/1000 μs waveform, low incremental surge resistance, and halogen-free RoHS-compliant construction-key selection criteria for high-reliability transient suppression in constrained PCB layouts.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging glass-passivated junction technology for stable reverse leakage (<1.0 μA at 185 V) and fast response time (<1.0 ns). Its thermal resistance (RθJA = 100 °C/W) and junction temperature limit (TJ max = 150 °C) define safe derating above 25 °C ambient per Figure 2 of the datasheet.
The device meets MSL Level 1 per J-STD-020 (peak reflow ≤260 °C), supports automated placement, and is qualified to AEC-Q101 when ordered with HE3/HM3 suffixes-though P6SMB220A-M3/52 itself is commercial-grade halogen-free RoHS-compliant without automotive qualification.
Key Specifications

Use Value: 1.0 μA max leakage at 185 V prevents battery drain in backup-supplied meters; 150 °C TJ max supports operation in sealed outdoor enclosures. |
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), VC = 328 V, but lower PPPM (400 W); SMA package (DO-214AC), larger RθJA (140 °C/W). | Limited to lower-energy surges; less suitable for IEC 61000-4-5 Level 4; requires larger pad area for thermal management. | Select when cost is prioritized over surge margin and board space allows SMA footprint. |
| 1.5SMC220A | Same VWM/VC specs, higher PPPM (1500 W), but larger SMC (DO-214AB) package and higher leakage (5.0 μA). | Better for high-reliability telecom infrastructure; overqualified for consumer-grade designs where size and leakage matter. | Choose when system-level surge testing exceeds 600 W or when legacy SMC footprints are fixed. |
Compared with SMAJ220A and 1.5SMC220A, P6SMB220A-M3/52 provides optimal balance of 600 W surge capacity, SMB footprint compactness, and sub-μA leakage-making it preferred for space-constrained industrial and automotive modules requiring commercial-grade reliability without overengineering.

FAQ
What is the maximum clamping voltage of P6SMB220A-M3/52 under standard test conditions?
The maximum clamping voltage (VC) of P6SMB220A-M3/52 is 328 V, measured at 1.8 A peak pulse current (IPPM) using a 10/1000 μs waveform. This value defines the highest voltage imposed on protected circuitry during surge events and is critical for ensuring downstream components remain within their absolute maximum ratings. The P6SMB220A-M3/52 achieves this clamping performance while maintaining low incremental surge resistance for efficient energy diversion.
Is P6SMB220A-M3/52 suitable for automotive applications requiring AEC-Q101 qualification?
No, P6SMB220A-M3/52 is not AEC-Q101 qualified. It is a commercial-grade, halogen-free, RoHS-compliant part. For automotive use, Vishay offers the P6SMB220AHM3_B variant (with HM3_B suffix), which adds AEC-Q101 qualification while retaining identical electrical specs and SMB packaging. Engineers must specify the HM3_B version explicitly when automotive qualification is required-P6SMB220A-M3/52 alone does not meet AEC-Q101 stress test requirements.
What is the thermal resistance and how does it affect PCB layout for P6SMB220A-M3/52?
P6SMB220A-M3/52 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. This value assumes minimal copper area; increasing pad size or adding internal ground planes reduces RθJA, improving surge endurance. Layouts must allocate ≥5.0 mm² copper per pad and avoid thermal isolation to prevent junction temperatures exceeding 150 °C during repetitive surges.
How does the leakage current of P6SMB220A-M3/52 compare to similar 220 V TVS diodes?
P6SMB220A-M3/52 exhibits ≤1.0 μA maximum reverse leakage current at its 185 V stand-off voltage (VWM), which is among the lowest in its class. This compares favorably to alternatives like SMAJ220A (≤5.0 μA) and 1.5SMC220A (≤5.0 μA), making P6SMB220A-M3/52 especially suitable for battery-backed or high-impedance sensor circuits where leakage could impact accuracy or runtime. The low leakage stems from Vishay's glass-passivated junction process.
What packaging and reel configuration does P6SMB220A-M3/52 ship in?
P6SMB220A-M3/52 ships in 7" diameter plastic tape and reel format (ordering code suffix /52), containing 750 units per reel. The tape conforms to EIA-481 standards, with pocket pitch of 8 mm and cover tape peel strength optimized for high-speed pick-and-place machines. The M3 suffix confirms halogen-free, RoHS-compliant construction, and the /52 designation specifies reel size and quantity-critical for SMT line planning and inventory forecasting.
