Product details
Overview
P6SMB180CA-E3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, rated for 180 V standoff voltage (VWM), 207 V minimum breakdown voltage (VBR), and 600 W peak pulse power (10/1000 μs). It clamps transients to ≤246 V at 2.4 A peak pulse current and operates across -65 °C to +150 °C junction temperature - deployed for ESD and surge protection on automotive sensor signal lines, industrial I/O ports, and telecom interface circuits.
For engineers reviewing the P6SMB180CA-E3/5B datasheet, P6SMB180CA-E3/5B pinout, P6SMB180CA-E3/5B application, or P6SMB180CA-E3/5B equivalent, key selection criteria include bidirectional clamping capability, 246 V maximum clamping voltage at rated IPPM, RoHS-compliant matte tin terminations, MSL Level 1 moisture sensitivity, and AEC-Q101 qualification eligibility via HE3/HM3 suffix variants.
Technical Context
This device functions as a voltage-clamping transient protector with symmetrical reverse/forward conduction behavior due to its bidirectional construction. It delivers 600 W peak pulse power handling per 10/1000 μs waveform at 0.01% duty cycle and exhibits low incremental surge resistance for effective energy diversion during fast-rising transients.
Designed for automated SMT placement, it features glass-passivated junctions, UL 94 V-0 molding compound, and J-STD-002/JESD 22-B102 solderable matte tin leads. Its thermal resistance is 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling reliable operation under repetitive surge conditions when mounted on 5.0 mm × 5.0 mm copper pads.
Key Specifications

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed between signal line and ground, responding within <1 ns to transients. Use Value: Limits induced voltage to ≤246 V, preventing damage to 3.3 V/5 V interface ICs while maintaining signal integrity during normal operation. |
Use Scenario: Shielding digital input modules in programmable logic controllers from field-wiring surge events (e.g., relay coil switching, lightning-induced coupling). IC Role / Device Role / Timing Role: Standoff-mode TVS connected across input terminals to shunt surge energy before reaching optocoupler or MCU GPIO. Use Value: Absorbs 600 W transient bursts without degradation, supporting long-term reliability in factory-floor environments with high EMI exposure. |
| Telecom Line Interface | Consumer Power Adapter ESD |
Use Scenario: Safeguarding Ethernet PHY interfaces, RS-485 transceivers, and DSL line drivers against ESD (IEC 61000-4-2) and lightning-induced surges. IC Role / Device Role / Timing Role: Primary-level clamping device placed at connector entry point, coordinated with secondary filtering. Use Value: Clamps 8 kV contact discharge transients to safe levels (<246 V) while exhibiting only 1.0 μA leakage at 180 V standby. |
Use Scenario: Adding robustness to USB-C or barrel-jack input stages in wall adapters against user-handling ESD and accidental AC line transients. IC Role / Device Role / Timing Role: Secondary-side transient suppressor across DC output rails, triggered after primary-side MOVs. Use Value: Provides precise 180 V standoff and sharp 246 V clamping to protect downstream DC-DC controllers without false triggering during brownouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180CA | Same VWM (180 V), identical SMB package, but lower PPPM (600 W same), slightly higher VC (252 V) | Marginally reduced clamping performance; otherwise functionally interchangeable in non-critical layouts | Select when sourcing flexibility is prioritized and 6 V higher clamping voltage is acceptable |
| 1.5SMC180CA | Higher package thermal mass (SMC/DO-214AB), same VWM/VC specs, but larger footprint (7.11 mm × 6.22 mm) | Requires PCB redesign; preferred where board space allows and higher thermal dissipation is needed | Choose for high-reliability industrial systems needing extended surge endurance beyond 1000 pulses |
Compared with P6SMB180CA-E3/5B, SMBJ180CA offers identical electrical protection in the same SMB footprint but with marginally relaxed clamping, while 1.5SMC180CA trades compactness for superior thermal robustness in larger SMC packaging - guiding selection based on layout constraints and lifetime surge count requirements.

FAQ
What does the "CA" suffix indicate in P6SMB180CA-E3/5B?
The "CA" suffix denotes a bidirectional configuration: the P6SMB180CA-E3/5B conducts and clamps symmetrically in both polarities, making it suitable for AC signal lines, differential buses, or any application where voltage transients may occur with either polarity. This differs from unidirectional "A"-suffix variants that require correct anode/cathode orientation relative to ground.
Is P6SMB180CA-E3/5B AEC-Q101 qualified?
The base P6SMB180CA-E3/5B is RoHS-compliant commercial-grade; however, AEC-Q101 qualification is available through the HE3 variant (e.g., P6SMB180CAHE3_B). That version undergoes stress testing per AEC-Q101 standards for automotive use, while P6SMB180CA-E3/5B itself is not certified but shares identical die and construction.
What is the maximum clamping voltage of P6SMB180CA-E3/5B at its rated peak pulse current?
The maximum clamping voltage (VC) of P6SMB180CA-E3/5B is 246 V at 2.4 A peak pulse current (IPPM), measured under the standard 10/1000 μs double-exponential waveform. This value ensures protected circuits remain below critical overvoltage thresholds during worst-case surge events.
Can P6SMB180CA-E3/5B be used in place of a unidirectional TVS like P6SMB180A-E3/5B?
No - P6SMB180CA-E3/5B is bidirectional and lacks polarity marking, while P6SMB180A-E3/5B is unidirectional with cathode band identification. Substituting them requires verifying circuit topology: bidirectional use cases (e.g., data lines) support P6SMB180CA-E3/5B, but unidirectional DC rails require the "A" variant to avoid forward conduction during normal operation.
What is the thermal resistance of P6SMB180CA-E3/5B, and how does it affect layout design?
P6SMB180CA-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead (RθJL) of 20 °C/W. To maintain reliability under repetitive surges, PCB layout must use minimum 5.0 mm × 5.0 mm copper pads per terminal - smaller pads increase thermal impedance and risk premature failure during sustained transient activity.
