Product details
Overview
P6SMB220CA-M3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, with 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. It delivers 600 W peak pulse power handling per 10/1000 μs waveform and is used for ESD and surge protection on DC power rails and signal lines in industrial sensor interfaces.
For engineers reviewing the P6SMB220CA-M3/52 datasheet, P6SMB220CA-M3/52 pinout, P6SMB220CA-M3/52 application, or P6SMB220CA-M3/52 equivalent, this device serves as a halogen-free, RoHS-compliant, commercial-grade TVS optimized for fast transient suppression in space-constrained PCB layouts with automated placement compatibility.
Technical Context
The P6SMB220CA-M3/52 operates bidirectionally with symmetrical clamping behavior in both polarities, enabling robust protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable leakage performance and low incremental surge resistance under repetitive transients.
Designed for operation up to +150 °C junction temperature and rated for 0.01 % duty cycle at 600 W, it leverages thermal resistance of 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads-making it suitable for thermally constrained consumer and industrial modules where heatsinking is limited.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 220 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin for protected line. |
| VBR (min) | 209 V at 1 mA - Ensures reliable conduction onset during overvoltage events above nominal system voltage. |
| VC (max) | 328 V at 1.8 A - Limits downstream voltage stress during 10/1000 μs surge; critical for IC-level survivability. |
| PPPM | 600 W - Peak pulse power rating per standard 10/1000 μs waveform; supports IEC 61000-4-5 Level 4 surge immunity. |
| IPPM | 1.8 A - Corresponding peak pulse current at VC; determines required trace width and layout impedance matching. |
| TJ max | +150 °C - Enables use in high-temperature environments such as automotive under-hood or industrial motor drives. |
| Package | SMB (DO-214AA) - Low-profile SMD outline (4.57 mm × 3.94 mm × 2.20 mm); compatible with J-STD-020 MSL level 1 reflow. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Cathode/anode terminals are symmetric; both ends function identically under reverse or forward transient conditions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Terminal 1 | Transient return path (bidirectional) | Connects to protected line; conducts during either polarity overvoltage event to shunt energy to ground or rail. |
| Cathode / Terminal 2 | Transient return path (bidirectional) | Electrically identical to Terminal 1; no functional distinction in CA-type devices; forms symmetrical clamp pair. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses, or floating nodes without external polarity management. |
| 600 W peak pulse power | Meets IEC 61000-4-5 surge immunity requirements for industrial equipment and telecom infrastructure. |
| Glass passivated junction | Ensures long-term stability of leakage current (<1 μA at VWM) and consistent VBR across temperature and life cycle. |
| Halogen-free & RoHS-compliant (M3 suffix) | Supports environmental compliance for global OEM programs without compromising surge performance or thermal reliability. |
| MSL level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking; simplifies SMT line integration and inventory handling. |
Applications
| Industrial Sensor Interface | DC Power Rail Protection |

Use Scenario: Guarding LIN bus lines and switch inputs in BCMs against battery reverse connection and jump-start induced transients. IC Role / Device Role / Timing Role: Bidirectional TVS bridging LIN line to chassis ground, suppressing ±100 V pulses per ISO 7637-2 Pulse 1/2a. Use Value: Maintains functional safety by limiting voltage excursion to <330 V during 100 V/50 ms pulses, ensuring microcontroller I/O remains within absolute maximum ratings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA-T | Same VWM/VC, but 600 W rating tested at 10/1000 μs with 0.01 % duty cycle; slightly higher RθJA (110 °C/W vs. 100 °C/W). | Identical use cases; minor thermal derating needed above 75 °C ambient in dense layouts. | Select when sourcing from Diodes Inc. preferred supply chain; verify thermal pad layout matches SMB footprint. |
| 1.5KE220CA | Through-hole DO-201 package; same electrical specs but larger footprint and higher inductance; 1.5 kW peak power rating. | Not suitable for high-density SMT designs; better for prototyping or legacy through-hole boards requiring higher single-pulse margin. | Choose only if board revision allows through-hole placement and mechanical robustness outweighs size constraints. |
Compared with SMBJ220CA-T and 1.5KE220CA, the P6SMB220CA-M3/52 offers optimal balance of compact SMB packaging, halogen-free compliance, and verified 600 W surge capability-making it ideal for volume production of modern industrial and automotive control modules where PCB real estate and environmental compliance are critical.

FAQ
What is the clamping voltage of P6SMB220CA-M3/52 at its rated peak pulse current?
The P6SMB220CA-M3/52 has a maximum clamping voltage (VC) of 328 V at 1.8 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB220CA-M3/52 maintains this clamping performance across its specified operating temperature range of –65 °C to +150 °C.
Is P6SMB220CA-M3/52 suitable for automotive applications?
The P6SMB220CA-M3/52 is a commercial-grade, halogen-free, RoHS-compliant TVS diode-not AEC-Q101 qualified. For automotive applications requiring qualification, Vishay offers the P6SMB220CAHM3_B variant (with HM3_B suffix). The P6SMB220CA-M3/52 may be used in non-safety-critical automotive subsystems (e.g., infotainment power rails) only after full system-level validation, but it is not certified for under-hood or safety-related functions.
How does the "CA" suffix in P6SMB220CA-M3/52 affect its functionality?
The "CA" suffix in P6SMB220CA-M3/52 denotes a bidirectional configuration-meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional "A" variants, the P6SMB220CA-M3/52 has no cathode marking and functions identically regardless of polarity, making it ideal for AC-coupled lines, differential buses, or floating grounds where polarity reversal is possible.
What is the thermal resistance of P6SMB220CA-M3/52, and how does it impact layout design?
The P6SMB220CA-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. To maintain safe junction temperatures under repetitive surges, PCB layout must provide adequate copper area and minimize trace inductance. Reducing pad size or omitting thermal vias increases RθJA, potentially derating the P6SMB220CA-M3/52's effective surge capability.
Does P6SMB220CA-M3/52 require special handling during reflow soldering?
No-P6SMB220CA-M3/52 meets J-STD-020 MSL level 1, meaning it has unlimited floor life and withstands standard lead-free reflow profiles (peak 260 °C) without baking or dry-pack requirements. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102, ensuring reliable wetting and intermetallic formation. The P6SMB220CA-M3/52 is fully compatible with automated SMT lines using standard process controls.
