Product details
Overview
P6SMB180CAHE3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 180 V standoff voltage (VWM), 246 V maximum clamping voltage (VC) at 2.4 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects signal lines and power rails in automotive sensor units, industrial I/O modules, and telecom interface circuits against ESD and inductive switching transients.
For engineers reviewing the P6SMB180CAHE3/5B datasheet, P6SMB180CAHE3/5B pinout, P6SMB180CAHE3/5B application, or P6SMB180CAHE3/5B equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 150 °C junction temperature rating, low incremental surge resistance, and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical breakdown behavior in both directions due to its bidirectional construction. Its glass-passivated junction enables fast response time (<1 ns) and stable clamping under repetitive 10/1000 μs surges at 0.01% duty cycle.
Designed for surface-mount use on 0.2" × 0.2" copper pads per terminal, it delivers thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), supporting reliable operation up to TJ = 150 °C without derating at TA ≤ 50 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 154 V - Maximum continuous reverse working voltage before clamping initiates; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 171–189 V at 1 mA - Confirmed voltage range where device transitions from high-impedance to low-impedance clamping state. |
| VC (Clamping Voltage) | 246 V at IPPM = 2.4 A - Peak voltage seen across protected circuit during worst-case 10/1000 μs transient; determines stress on downstream ICs. |
| PPPM (Peak Pulse Power) | 600 W - Sustained transient energy absorption capacity per single 10/1000 μs event; enables robust protection against lightning-induced surges. |
| TJ max. | 150 °C - Maximum allowable junction temperature; supports extended operation in under-hood automotive and industrial environments. |
| Package | SMB (DO-214AA) - Low-profile surface-mount outline with 5.59 mm × 4.06 mm footprint; optimized for automated pick-and-place and reflow soldering. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, humidity testing, and mechanical shock per AEC specification. |
Pinout & Package

| Telecom Line Card Surge Protection | Consumer Appliance Motor Control |
|
Use Scenario: Front-end protection of DSL/VDSL line drivers and Ethernet PHYs against lightning-induced surges entering via outdoor cabling. IC Role / Device Role / Timing Role: Primary-level TVS on line-side traces, coordinated with GDT or MOV secondary protection stages. Use Value: Absorbs 600 W transient energy while limiting let-through voltage to <246 V, enabling use of lower-voltage-rated PHY ICs (e.g., RTL8211FD). |
Use Scenario: Suppressing inductive kickback from brushed DC motors in smart home appliances (e.g., washing machine drum drives). IC Role / Device Role / Timing Role: Parallel-mounted TVS across motor terminals to clamp flyback spikes before reaching H-bridge MOSFETs or gate drivers. Use Value: Limits voltage overshoot to 246 V during 100 A turn-off events, reducing MOSFET avalanche stress and extending FET lifetime in STP16NF06L-based designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ180CA | Same VWM (154 V), VC = 246 V, but rated for 400 W PPPM and packaged in smaller SMA (DO-214AC); not AEC-Q101 qualified. | Limited to commercial-grade consumer/industrial use; unsuitable for automotive under-hood deployment. | Select when cost or board space is critical and AEC-Q101 compliance is not required. |
| 1.5KE180CA | Through-hole TO-218 package; same VWM/VC ratings but higher thermal mass; 600 W rating applies only with heatsink; no MSL Level 1 rating. | Requires manual or wave-solder assembly; incompatible with high-speed SMT lines; less suitable for compact PCBs. | Choose for legacy through-hole designs or high-reliability power supply inputs where thermal dissipation dominates. |
Compared with SMAJ180CA and 1.5KE180CA, P6SMB180CAHE3/5B uniquely combines AEC-Q101 qualification, SMB surface-mount compatibility, MSL Level 1 reflow readiness, and full 600 W rating in a low-profile package-making it optimal for next-generation automotive and industrial SMT platforms.

FAQ
What is the clamping voltage of P6SMB180CAHE3/5B at its rated peak pulse current?
The P6SMB180CAHE3/5B has a maximum clamping voltage (VC) of 246 V at its specified peak pulse current (IPPM) of 2.4 A under a 10/1000 μs waveform. This value is measured per JEDEC standards and ensures predictable overvoltage limiting for downstream components such as RS-485 transceivers or automotive microcontrollers. The clamping performance remains consistent across temperature ranges from −65 °C to +150 °C.
Is P6SMB180CAHE3/5B suitable for automotive applications?
Yes, P6SMB180CAHE3/5B is AEC-Q101 qualified (denoted by the HE3 suffix) and specifically designed for automotive use cases including engine control units, ADAS sensor interfaces, and body electronics. It passes rigorous stress tests for temperature cycling, humidity, and mechanical shock, and supports operation up to 150 °C junction temperature-meeting under-hood environmental requirements.
How does the bidirectional design of P6SMB180CAHE3/5B affect PCB layout?
The bidirectional nature of P6SMB180CAHE3/5B eliminates polarity concerns during placement: either terminal may connect to either side of a differential pair or AC-coupled line. No cathode band marking is present, simplifying layout and reducing risk of orientation errors. For optimal performance, mount it directly at the protected node using minimum trace length and 0.2" × 0.2" copper pads per terminal as specified in the Vishay datasheet.
What is the maximum steady-state power dissipation of P6SMB180CAHE3/5B?
P6SMB180CAHE3/5B has a maximum steady-state power dissipation (PD) of 5.0 W when mounted on an infinite heatsink at ambient temperature (TA) of 50 °C. In typical PCB applications without heatsinking, derating applies above 25 °C ambient per Figure 2 in the datasheet; at 70 °C TA, usable PD drops to approximately 3.5 W. This rating governs continuous leakage and bias conditions-not transient events.
Does P6SMB180CAHE3/5B meet RoHS and halogen-free requirements?
Yes, P6SMB180CAHE3/5B is RoHS-compliant and halogen-free, as confirmed by the "HE3" suffix and Vishay's material categorization documentation (www.vishay.com/doc?99912). It contains no brominated flame retardants, antimony trioxide, or other restricted substances, and complies with JEDEC J-STD-20 and JESD22-B102 for solderability and whisker resistance.
