Product details
Overview
P6SMB160CAHM3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal and power lines. It features a 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 capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB160CAHM3_A/H datasheet, P6SMB160CAHM3_A/H pinout, P6SMB160CAHM3_A/H application, or P6SMB160CAHM3_A/H equivalent, key selection criteria include bidirectional clamping behavior, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status, and thermal resistance (RθJA = 100 °C/W) for board-level surge protection design.
Technical Context
This device operates as a voltage-clamping transient suppressor with symmetrical breakdown characteristics in both directions due to its bidirectional construction. It exhibits a typical breakdown voltage (VBR) range of 185 V to 207 V at 1 mA test current, with a temperature coefficient of 0.108 %/°C - enabling stable overvoltage protection across automotive-grade temperature ranges (–65 °C to +150 °C).
The P6SMB160CAHM3_A/H uses a glass-passivated silicon junction and is rated for 600 W peak pulse power under standardized 10/1000 μs waveform conditions at 0.01 % duty cycle. Its low incremental surge resistance and fast response time ensure effective suppression of ESD, lightning-induced surges, and inductive switching transients without significant voltage overshoot.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown |
| VBR (Breakdown Voltage) | 152–168 V at IT = 1 mA - ensures reliable triggering during overvoltage events with tight tolerance |
| VC (Clamping Voltage) | 219 V at IPPM = 2.7 A - limits transient voltage seen by protected downstream circuitry |
| PPPM (Peak Pulse Power) | 600 W - sustains high-energy transients per 10/1000 μs waveform without failure |
| RθJA | 100 °C/W - determines thermal rise under sustained power dissipation; requires appropriate PCB copper area |
| TJ max. | +150 °C - supports operation in under-hood automotive and industrial environments |
| AEC-Q101 Qualified | Yes - certified for automotive electronic systems per stress-test requirements |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant, with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Molding compound meets UL 94 V-0 flammability rating. Bidirectional configuration has no polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode / Anode (symmetrical) | Transient conduction path | Both terminals function identically; conducts surge current in either direction when voltage exceeds VBR |
Key Features
| Feature | Design Value |

| Low profile SMB package | 0.220" × 0.130" footprint supports automated SMT assembly and space-constrained PCB layouts |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without moisture sensitivity handling |
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 ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Voltage clamping element placed directly at connector or IC input pins to shunt transient energy to ground. Use Value: Prevents latch-up or permanent damage to 3.3 V/5 V interface ICs during 12 V/24 V system transients up to 600 W. |
Use Scenario: Safeguarding digital input/output modules in programmable logic controllers exposed to relay coil flyback and motor drive noise. IC Role / Device Role / Timing Role: Primary surge suppression device on field-side signal traces before optocoupler or level-shifter isolation barriers. Use Value: Maintains functional safety integrity by limiting transient voltage to <219 V during 10/1000 μs surges, preserving isolation barrier reliability. |
| Telecom Line Interface | Consumer Appliance Motor Control |
Use Scenario: Shielding Ethernet PHYs and DSL line drivers from induced surges on outdoor cabling in network equipment. IC Role / Device Role / Timing Role: Secondary protection stage after gas discharge tube (GDT), providing fast-response clamping near IC pins. Use Value: Reduces clamping voltage overshoot to protect 1.8 V/2.5 V PHYs while sustaining repetitive surge events per Telcordia GR-1089. |
Use Scenario: Suppressing commutation spikes from brushed DC motors in washing machines, HVAC blowers, and power tools. IC Role / Device Role / Timing Role: Parallel-connected TVS across motor terminals or H-bridge outputs to clamp inductive kickback. Use Value: Eliminates need for snubber RC networks by absorbing 600 W pulses, reducing BOM count and board area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA | Same VWM (136 V), identical SMB package, but rated for 600 W with tighter VC = 219 V and lower RθJA = 80 °C/W | Preferred where higher thermal efficiency is required on compact PCBs with limited copper area | Select SMBJ160CA if board layout allows tighter thermal management and lower clamping variance is critical |
| 1.5KE160CA | Higher power (1500 W), axial DO-15 package, VWM = 136 V, VC = 259 V - larger footprint and slower response than SMB | Suitable for non-SMT legacy designs or high-energy primary protection stages before secondary TVS | Choose 1.5KE160CA only when through-hole mounting is mandatory or >600 W surge handling is required |
Compared with SMBJ160CA and 1.5KE160CA, the P6SMB160CAHM3_A/H offers AEC-Q101 qualification and halogen-free compliance in a low-profile SMB package - making it optimal for automotive and space-constrained industrial SMT designs requiring validated reliability and regulatory alignment.

FAQ
What does the "CA" suffix indicate in P6SMB160CAHM3_A/H?
The "CA" suffix denotes a bidirectional configuration, meaning the P6SMB160CAHM3_A/H provides symmetrical clamping in both forward and reverse directions. This eliminates polarity concerns during placement and enables protection of AC-coupled or floating signal paths - unlike unidirectional variants (e.g., P6SMB160A) which require cathode orientation alignment. The CA version is specified with matched VBR min/max in both directions.
Is P6SMB160CAHM3_A/H suitable for automotive applications?
Yes, P6SMB160CAHM3_A/H is AEC-Q101 qualified (indicated by the HM3 suffix), confirming it has passed stress tests for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock. It is commonly deployed in engine control units, body control modules, and ADAS sensor interfaces where transient immunity to load dump and ISO 7637-2 pulses is required.
How does the SMB (DO-214AA) package of P6SMB160CAHM3_A/H compare to SMA or SMC packages?
The SMB (DO-214AA) package of P6SMB160CAHM3_A/H measures 3.94 mm × 2.20 mm with a 2.18 mm minimum cathode band width - smaller than SMC (DO-214AB) but larger than SMA (DO-214AC). This gives P6SMB160CAHM3_A/H a balance of power handling (600 W), board density, and thermal performance. Unlike SMA, SMB supports higher surge ratings; unlike SMC, it fits tighter pitch layouts without sacrificing clamping consistency.
What is the significance of the "HM3" and "_A/H" in P6SMB160CAHM3_A/H?
The "HM3" suffix indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification; "_A/H" specifies packaging: "A" denotes the revision code, and "H" means supplied in 7" diameter plastic tape-and-reel format (750 units per reel). This ensures traceability, environmental compliance, and compatibility with high-speed pick-and-place equipment for automotive and industrial manufacturing lines using P6SMB160CAHM3_A/H.
Can P6SMB160CAHM3_A/H replace older P6SMB160CA-E3 parts in existing designs?
Yes, P6SMB160CAHM3_A/H is a direct drop-in replacement for P6SMB160CA-E3 in most cases: same electrical specs (VWM = 136 V, VC = 219 V), identical SMB package dimensions, and compatible soldering profiles. The HM3 version adds halogen-free materials and AEC-Q101 qualification - beneficial for automotive upgrades - while maintaining full form-fit-function compatibility with the E3 variant in P6SMB160CAHM3_A/H-based designs.
