Product details
Overview
P6SMB11CA-M3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 11 V standoff voltage (VWM), 12.1 V minimum breakdown voltage (VBR), 15.6 V maximum clamping voltage at 38.5 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB11CA-M3/5B datasheet, P6SMB11CA-M3/5B pinout, P6SMB11CA-M3/5B application, or P6SMB11CA-M3/5B equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, thermal resistance (RθJA = 100 °C/W), AEC-Q101 qualification status, and halogen-free RoHS compliance per M3 suffix - critical for ESD/surge protection design validation and BOM selection.
Technical Context
The P6SMB11CA-M3/5B operates as a bidirectional TVS diode, symmetrically clamping overvoltage events in both polarities without polarity marking. Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, supporting repetitive 0.01% duty cycle surges per JEDEC standards.
It is rated for 150 °C maximum junction temperature and mounted on 5.0 mm × 5.0 mm copper pads per test condition. Thermal resistance from junction to ambient is 100 °C/W, and junction-to-lead is 20 °C/W - enabling reliable operation under transient stress in compact PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 9.40 V - maximum reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 10.5–11.6 V at 1 mA - guaranteed conduction onset range; ensures predictable turn-on during transients |
| VC (Clamping Voltage) | 15.6 V at 38.5 A IPPM - peak voltage seen by protected circuit during 600 W surge; limits stress on downstream components |
| PPPM | 600 W - peak pulse power handling with 10/1000 μs waveform; supports IEC 61000-4-5 Level 4 surge immunity |
| ID (Leakage Current) | 5.0 μA max at VWM - minimal standby power loss and signal integrity impact in high-impedance circuits |
| TJ max | 150 °C - enables use in under-hood automotive and industrial environments without derating at 85 °C ambient |
| Package | SMB (DO-214AA) - standardized surface-mount footprint compatible with automated placement and reflow soldering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11CA | Same VWM (9.4 V) and VC (15.6 V), but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA = 140 °C/W) | Less suitable for high-energy surges (>400 W); preferred where board space is constrained and thermal mass limited | Select SMAJ11CA only when surge energy is confirmed ≤400 W and layout cannot accommodate SMB pad size. |
| 1.5KE11CA | Higher PPPM (1500 W), axial-leaded DO-201 package; larger size, manual assembly; VWM = 9.4 V, VC = 16.5 V | Used in legacy through-hole designs or high-reliability power supplies requiring >600 W headroom | Choose 1.5KE11CA for through-hole prototyping or where mechanical robustness outweighs SMT automation benefits. |
Compared with SMAJ11CA and 1.5KE11CA, the P6SMB11CA-M3/5B delivers optimal balance of 600 W surge capability, SMB surface-mount compatibility, and halogen-free AEC-Q101 readiness - making it the preferred choice for new automotive and industrial SMT designs requiring validated surge immunity without layout compromise.

FAQ
What is the clamping voltage of the P6SMB11CA-M3/5B at its rated peak pulse current?
The P6SMB11CA-M3/5B has a maximum clamping voltage (VC) of 15.6 V at 38.5 A peak pulse current (IPPM), measured with a 10/1000 μs waveform. This value is specified in the Vishay datasheet (Document Number: 88370, Rev. 09-Jan-2024) and defines the upper voltage limit imposed on protected circuitry during a full-rated surge event. The P6SMB11CA-M3/5B maintains this clamping performance across its operational temperature range and after repeated surges within duty cycle limits.
Is the P6SMB11CA-M3/5B suitable for automotive applications?
Yes - the P6SMB11CA-M3/5B is AEC-Q101 qualified when ordered with the "_B" revision suffix (e.g., P6SMB11CA-M3/5B-B), as confirmed in Vishay's ordering information table. It undergoes stress testing including high-temperature gate bias, temperature cycling, and humidity testing per automotive reliability standards. The P6SMB11CA-M3/5B meets these requirements in its halogen-free, RoHS-compliant M3 configuration and is widely deployed in automotive sensor units and body control modules.
What does the "CA" suffix indicate in P6SMB11CA-M3/5B?
The "CA" suffix in P6SMB11CA-M3/5B denotes a bidirectional Transient Voltage Suppressor configuration. Unlike unidirectional variants (e.g., P6SMB11A), the CA version provides symmetrical clamping in both polarities - essential for protecting AC-coupled signals, differential buses (e.g., CAN, RS-485), or floating power rails. Electrical characteristics such as VWM, VBR, and VC apply identically in either direction, and the device carries no polarity marking on the SMB package.
How does the M3 suffix affect the P6SMB11CA-M3/5B's compliance profile?
The "M3" suffix indicates that the P6SMB11CA-M3/5B is halogen-free and RoHS-compliant per EU Directive 2011/65/EU and IPC-1752A, with brominated flame retardants replaced by alternative chemistries. It also meets JESD201 Class 2 whisker resistance and achieves MSL Level 1 moisture sensitivity. This makes the P6SMB11CA-M3/5B suitable for environmentally regulated industries including automotive, medical, and industrial automation where material declarations and green manufacturing are mandatory.
What is the thermal resistance of the P6SMB11CA-M3/5B, and how does it impact layout design?
The P6SMB11CA-M3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per datasheet test condition. This value guides PCB layout: increasing pad area or adding thermal vias reduces effective RθJA, allowing higher average power dissipation. For continuous operation near PD = 5.0 W, thermal management must ensure TJ remains ≤150 °C. The P6SMB11CA-M3/5B's RθJL of 20 °C/W further supports heat transfer to leads in high-current pulse scenarios.
