Product details
Overview
P6SMB160CA-M3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 160 V standoff voltage (VWM), 219 V maximum clamping voltage (VC) at 2.7 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs waveform). It protects signal lines and power rails in automotive sensor interfaces, industrial I/O modules, and telecom line cards against ESD and inductive switching transients.
For engineers reviewing the P6SMB160CA-M3/52 datasheet, P6SMB160CA-M3/52 pinout, P6SMB160CA-M3/52 application, or P6SMB160CA-M3/52 equivalent, key selection criteria include bidirectional clamping symmetry, halogen-free RoHS compliance (M3 suffix), 150 °C max junction temperature, and compatibility with automated SMT placement on standard PCB pad layouts per JEDEC DO-214AA.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical breakdown behavior in both polarities-no cathode/anode distinction-enabling direct placement across differential or AC-coupled signal paths. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns), critical for protecting high-speed analog inputs and microcontroller GPIOs.
The P6SMB160CA-M3/52 delivers 600 W peak pulse power handling under standardized 10/1000 μs transients while maintaining low incremental surge resistance and thermal resistance of 100 °C/W (junction-to-ambient, on 5.0 mm × 5.0 mm copper pads). It meets MSL Level 1 and is qualified to JESD201 Class 2 whisker resistance standards.
Key Specifications

FAQ
What is the clamping voltage of the P6SMB160CA-M3/52 at its rated peak pulse current?
The P6SMB160CA-M3/52 has a maximum clamping voltage (VC) of 219 V at 2.7 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 P6SMB160CA-M3/52 maintains this clamping performance across its full operating temperature range of -65 °C to +150 °C.
Is the P6SMB160CA-M3/52 suitable for automotive applications?
Yes-the P6SMB160CA-M3/52 is halogen-free and RoHS-compliant, but it is not AEC-Q101 qualified. For automotive use, Vishay offers the P6SMB160CAHM3_B variant (with HM3_B suffix), which adds AEC-Q101 qualification. The P6SMB160CA-M3/52 remains appropriate for non-safety-critical automotive subsystems such as infotainment or body electronics where formal qualification is not mandated. Always verify system-level compliance requirements before selecting the P6SMB160CA-M3/52.
How does the M3 suffix affect the P6SMB160CA-M3/52's compliance and processing?
The M3 suffix on the P6SMB160CA-M3/52 indicates halogen-free, RoHS-compliant construction with matte tin-plated leads meeting J-STD-002 and JESD22-B102 solderability standards. It also satisfies JESD201 Class 2 whisker resistance requirements. Unlike E3-suffix parts, M3 devices contain no brominated flame retardants or chlorine-based compounds, aligning with IPC-1752A material declarations. The P6SMB160CA-M3/52 is rated for MSL Level 1 and withstands peak reflow temperatures up to 260 °C.
What is the reverse leakage current specification for the P6SMB160CA-M3/52 at its stand-off voltage?
The P6SMB160CA-M3/52 exhibits a maximum reverse leakage current (ID) of 1.0 μA at its rated stand-off voltage (VWM) of 136 V, measured at 25 °C. This low leakage ensures minimal power loss in high-impedance circuits and prevents false triggering in precision bias networks. Leakage remains below 5.0 μA up to 125 °C ambient, supporting reliable operation in thermally demanding environments where the P6SMB160CA-M3/52 is deployed.
Can the P6SMB160CA-M3/52 be used in bidirectional signal line protection without polarity concerns?
Yes-the CA suffix denotes bidirectional functionality, meaning the P6SMB160CA-M3/52 provides symmetrical clamping in both forward and reverse directions with identical VBR, VC, and IPPM characteristics. There is no cathode band or polarity marking; either terminal may connect to either side of a differential pair, AC-coupled line, or floating power rail. This eliminates orientation errors during automated placement and simplifies layout for RS-485, CAN FD, or audio signal paths where the P6SMB160CA-M3/52 is commonly applied.
