Product details
Overview
P6SMB160CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 160 V standoff voltage (VWM), 179 V minimum breakdown voltage (VBR), 219 V maximum clamping voltage (VC) at 2.7 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) capability with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in industrial and automotive electronics.
For engineers reviewing the P6SMB160CAHM3/I datasheet, P6SMB160CAHM3/I pinout, P6SMB160CAHM3/I application, or P6SMB160CAHM3/I equivalent, key selection criteria include bidirectional clamping performance, AEC-Q101 qualification status, MSL Level 1 moisture sensitivity, halogen-free RoHS compliance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering consistent clamping behavior during positive and negative transients without polarity marking. Its glass-passivated junction ensures stable leakage and fast response (<1 ns), while low incremental surge resistance enables effective energy diversion under repetitive 0.01% duty cycle surges.
The device is rated for 150 °C maximum junction temperature and exhibits a typical thermal resistance of 100 °C/W (junction-to-ambient) when mounted per recommended pad layout. Its 20 °C/W junction-to-lead thermal resistance supports reliable power dissipation up to 5.0 W under continuous operation at 50 °C ambient.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160CA | Same VWM (136 V), lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 140 °C/W). | Limited to lower-energy transients; less suitable for industrial 4 kV surge environments requiring 600 W headroom. | Select when board space is constrained and thermal management allows higher junction temperature rise. |
| 1.5KE160CA | Higher power (1500 W), axial-leaded DO-15 package, larger size, not SMT-compatible. | Requires through-hole assembly and manual rework; incompatible with automated SMT lines and dense PCB layouts. | Choose only for legacy through-hole designs or where higher single-pulse energy absorption is mandatory. |

FAQ
What is the clamping voltage of P6SMB160CAHM3/I at its rated peak pulse current?
The P6SMB160CAHM3/I has a maximum clamping voltage (VC) of 219 V at 2.7 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The clamping performance is guaranteed across the full operating temperature range and confirms suitability for protecting 150 V-rated components in industrial and automotive applications.
Is P6SMB160CAHM3/I suitable for automotive applications?
Yes, P6SMB160CAHM3/I is AEC-Q101 qualified (indicated by the "HM3" suffix), meaning it has passed rigorous stress tests including temperature cycling, high-temperature reverse bias, and ESD verification. Its bidirectional architecture, 150 °C junction rating, and MSL Level 1 handling make it appropriate for engine control units, ADAS sensors, and body electronics where reliability under thermal and electrical stress is critical.
What does the "CA" suffix mean in P6SMB160CAHM3/I?
The "CA" suffix in P6SMB160CAHM3/I denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P6SMB160A), this part has no polarity marking and functions identically regardless of voltage polarity applied across its terminals, simplifying layout and eliminating orientation errors during SMT assembly.
What is the thermal resistance of P6SMB160CAHM3/I, and how does it affect PCB layout?
P6SMB160CAHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimum recommended pad layout per Vishay specification; reducing pad area increases thermal resistance and may require derating. For continuous 5.0 W power dissipation, ambient temperature must remain ≤50 °C to keep junction temperature within the 150 °C limit.
How does the M3 suffix in P6SMB160CAHM3/I impact compliance and assembly?
The "M3" suffix in P6SMB160CAHM3/I indicates halogen-free, RoHS-compliant construction with matte tin-plated leads that meet J-STD-002 and JESD 22-B102 solderability standards. It also satisfies JESD 201 Class 2 whisker resistance requirements. These attributes ensure compatibility with lead-free reflow processes (peak 260 °C), eliminate halogen-related corrosion risks, and support environmentally regulated markets including EU and China RoHS.
