Product details
Overview
P6SMB220CA-E3/5B from Vishay General Semiconductor is a bidirectional 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 600 W peak pulse power (10/1000 μs). It clamps transients to ≤328 V at 1.8 A peak pulse current and is used for protecting signal lines and power rails in industrial sensor interfaces and telecom equipment.
For engineers reviewing the P6SMB220CA-E3/5B datasheet, P6SMB220CA-E3/5B pinout, P6SMB220CA-E3/5B application, or P6SMB220CA-E3/5B equivalent, key selection criteria include bidirectional clamping capability, 220 V stand-off rating, 328 V max clamping voltage at IPPM, RoHS-compliant matte tin terminals, and MSL Level 1 reflow compatibility up to 260 °C.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional CA construction, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM).
The device delivers 600 W surge handling per 10/1000 μs waveform with <1 ns response time and low incremental surge resistance, supporting repetitive transient suppression at 0.01% duty cycle. Thermal resistance is 100 °C/W junction-to-ambient on standard 5.0 mm × 5.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 220 V - Maximum continuous reverse voltage before clamping begins; defines operating margin for 220 V nominal systems. |
| VBR (Breakdown) | 209–231 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on within ±5% tolerance. |
| VC (Clamping) | 328 V at 1.8 A - Peak voltage seen by protected circuit during 10/1000 μs surge; limits stress on downstream ICs. |
| PPPM | 600 W - Sustains single 10/1000 μs transients up to this energy level without failure; validated per Fig. 1 curve. |
| ID (Leakage) | ≤1.0 μA at 220 V - Negligible standby current; avoids loading sensitive high-impedance sensor or reference nodes. |
| TJ max | +150 °C - Enables operation in under-hood automotive or industrial enclosures with elevated ambient temperatures. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with automated pick-and-place. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case meeting UL 94 V-0; matte tin-plated leads solderable per J-STD-002; no polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (either direction) | Acts as cathode during positive half-cycle; enables symmetrical clamping across both polarities. |
| Cathode | Transient current exit (either direction) | Acts as anode during negative half-cycle; eliminates need for orientation-aware PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC, differential, or floating signal lines without polarity constraints or external diode pairing. |
| 600 W peak pulse power | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-earth) when properly mounted on 5 mm × 5 mm copper pads. |
| MSL Level 1 rating | Supports lead-free reflow up to 260 °C peak without moisture-induced damage; no bake-out required before assembly. |
| Glass passivated junction | Ensures long-term stability of VBR and low leakage drift over temperature and lifetime (>1000 h HTOL). |
| AEC-Q101 qualified option | Variant P6SMB220CAHE3_B meets automotive reliability standards; this E3/5B version is commercial-grade. |
Applications
| Industrial Sensor Interface | Telecom Line Protection |
|---|---|
|
Use Scenario: Protecting RS-485 transceivers and analog sensor outputs (e.g., 4–20 mA loops) from ESD and lightning-induced surges in factory automation cabinets. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across differential pair or supply rail to shunt transients before they reach IC input pins. Use Value: Limits clamped voltage to 328 V while sustaining 600 W pulses, preserving signal integrity and preventing latch-up in 3.3 V/5 V interface ICs. |
Use Scenario: Safeguarding Ethernet PHYs and DSL line drivers against induced surges on twisted-pair telecom lines exposed to outdoor environments. IC Role / Device Role / Timing Role: Primary surge suppressor at line entry point, coordinated with GDT or MOV secondary protection stages. Use Value: Fast sub-nanosecond response and low clamping voltage prevent data corruption and PHY damage during fast-rising transients. |
| Power Supply Input Stage | Automotive Body Control Module |
|
Use Scenario: Secondary overvoltage protection on 24 V DC input rails of industrial PLCs and embedded controllers subjected to load dump or inductive switching. IC Role / Device Role / Timing Role: Standoff-rated TVS placed after primary filtering to absorb residual energy not handled by upstream components. Use Value: 220 V VWM provides margin above 24 V system with 100% tolerance; 328 V VC prevents MOSFET gate oxide breakdown. |
Use Scenario: Protecting LIN bus transceivers and microcontroller I/Os in non-safety-critical body electronics (e.g., door modules, seat controls). IC Role / Device Role / Timing Role: Board-level ESD and transient suppressor on LIN data lines and power inputs per ISO 10605 and ISO 7637-2. Use Value: Bidirectional behavior matches LIN's single-wire topology; RoHS-compliant E3 termination supports automotive manufacturing requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ220CA | Same VWM/VBR/VC ratings but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA = 140 °C/W). | Limited to lower-energy transients; less suitable for IEC 61000-4-5 Level 4 without derating. | Select when board space is constrained and surge energy is ≤400 W; verify thermal margin on smaller pads. |
| 1.5KE220CA | Higher PPPM (1500 W), axial-leaded DO-201 package; slower response (~5 ns), larger mounting area required. | Better for high-energy surges but incompatible with SMT-only assembly; unsuitable for dense PCB layouts. | Choose for legacy through-hole designs or where 1500 W headroom is mandatory; avoid for new SMT platforms. |
Compared with SMAJ220CA and 1.5KE220CA, P6SMB220CA-E3/5B delivers optimal balance of 600 W surge capability, SMB footprint compatibility, and bidirectional performance for modern SMT industrial and telecom designs-without requiring layout changes or thermal redesign.

FAQ
What is the maximum clamping voltage of the P6SMB220CA-E3/5B under standard test conditions?
The P6SMB220CA-E3/5B has a maximum clamping voltage (VC) of 328 V when subjected to its rated peak pulse current of 1.8 A using a 10/1000 μs waveform. This value is measured at TJ = 25 °C with devices mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per the Vishay datasheet Figure 1 and Table on page 2. The P6SMB220CA-E3/5B maintains this clamping performance across its specified operating temperature range.
Is the P6SMB220CA-E3/5B suitable for automotive applications?
The P6SMB220CA-E3/5B is a commercial-grade variant with RoHS-compliant matte tin plating and MSL Level 1 rating, but it is not AEC-Q101 qualified. For automotive use, Vishay offers the P6SMB220CAHE3_B variant (with "_B" suffix), which meets AEC-Q101 stress testing requirements. The P6SMB220CA-E3/5B may be used in non-safety-critical automotive subsystems only after full system-level validation.
What does the "CA" suffix indicate in P6SMB220CA-E3/5B?
The "CA" suffix in P6SMB220CA-E3/5B denotes a bidirectional configuration: the device functions identically in both forward and reverse bias, making it suitable for protecting AC-coupled signals, differential buses (e.g., RS-485), or floating power rails. Unlike unidirectional "A" variants, the P6SMB220CA-E3/5B has no cathode band marking and exhibits symmetric VBR and VC characteristics in either direction.
How does the SMB package of the P6SMB220CA-E3/5B compare to SMA or SMC alternatives?
The SMB (DO-214AA) package of the P6SMB220CA-E3/5B measures 4.57 mm × 3.94 mm with a 2.20 mm height-smaller than SMC (DO-214AB) but larger than SMA (DO-214AC). It offers higher power handling (600 W) than SMAJ-series (400 W) while maintaining compatibility with standard SMT placement equipment. The P6SMB220CA-E3/5B's RθJA of 100 °C/W reflects optimized thermal path design for its size.
What is the leakage current specification for the P6SMB220CA-E3/5B at its rated standoff voltage?
At the rated standoff voltage (VWM) of 220 V and TA = 25 °C, the P6SMB220CA-E3/5B exhibits a maximum reverse leakage current (ID) of 1.0 μA. This low leakage ensures minimal loading on high-impedance circuits such as precision sensor references or battery-monitoring inputs. Leakage remains below 5 μA up to TJ = 125 °C per Vishay's derating curves.
