Product details
Overview
P6SMB160CAHM3_A/I 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 or 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, and 600 W peak pulse power rating with 10/1000 μs waveform - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P6SMB160CAHM3_A/I datasheet, P6SMB160CAHM3_A/I pinout, P6SMB160CAHM3_A/I application, or P6SMB160CAHM3_A/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMB (DO-214AA) package compatibility, and compliance with IEC 61000-4-2/4-4/4-5 transient immunity requirements.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping performance in forward and reverse directions. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the low incremental surge resistance enables effective energy diversion during ESD or lightning-induced surges.
The device is rated for 150 °C maximum junction temperature and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its thermal resistance (RθJA = 100 °C/W) supports operation on standard 0.2" × 0.2" copper pads without forced cooling in most industrial and automotive PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse voltage before clamping initiates; defines operating margin below breakdown. |
| VBR (Breakdown Voltage) | 152–168 V at 1.0 mA test current - Ensures predictable, repeatable turn-on threshold under transient stress. |
| VC (Clamping Voltage) | 219 V at 2.7 A IPPM - Limits voltage seen by downstream ICs during 10/1000 μs surge events. |
| PPPM (Peak Pulse Power) | 600 W - Sustains high-energy transients (e.g., ISO 7637-2 Pulse 1/2a/5a) without failure. |
| ID (Reverse Leakage) | ≤1.0 μA at 136 V - Minimizes standby power loss and avoids false triggering in high-impedance circuits. |
| TJ max. | 150 °C - Enables reliable operation in under-hood automotive environments and enclosed industrial enclosures. |
| AEC-Q101 Qualified | Yes - Validated for automotive applications including engine control modules and ADAS sensor interfaces. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant, matte tin-plated terminals. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H). Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal per Vishay recommended layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias | Symmetric terminal - no polarity marking; functions identically as cathode in reverse bias due to bidirectional design. |
| Cathode | Current exit point in forward bias | Symmetric terminal - no polarity marking; functions identically as anode in reverse bias; bidirectional conduction eliminates orientation dependency during placement. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or differential signal lines (e.g., CAN, RS-485) without polarity concerns. |
| 600 W peak pulse power (10/1000 μs) | Withstands automotive load dump and inductive switching surges per ISO 7637-2 without degradation. |
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive-grade reliability including temperature cycling, humidity testing, and mechanical shock. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage stress on protected ICs compared to higher-ratio suppressors, improving system robustness. |
| MSL Level 1, 260 °C peak reflow | Supports standard lead-free SMT assembly without moisture sensitivity handling or baking requirements. |

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), VC = 221 V, non-AEC-Q101, M3 suffix only (halogen-free/RoHS) | Lacks automotive qualification; suitable for commercial/industrial use only | Select when AEC-Q101 is not required and cost optimization is prioritized. |
| 1.5SMC160CA | Higher package thermal resistance (RθJA = 125 °C/W), same electrical specs, DO-214AB (SMC) package | Larger footprint (7.11 mm × 6.22 mm) limits high-density layouts | Choose only if existing PCB uses SMC pads or higher power derating margin is needed. |
Compared with SMBJ160CA and 1.5SMC160CA, P6SMB160CAHM3_A/I provides AEC-Q101 validation in the smallest standardized SMB footprint, enabling direct replacement in automotive designs without layout change - whereas SMBJ160CA lacks qualification and 1.5SMC160CA requires board redesign.

FAQ
What does the "CA" suffix indicate in P6SMB160CAHM3_A/I?
The "CA" suffix denotes a bidirectional configuration - meaning P6SMB160CAHM3_A/I clamps voltage transients equally in both polarities, unlike unidirectional "A" variants. This makes P6SMB160CAHM3_A/I ideal for protecting AC-coupled signals, differential buses (e.g., CAN, RS-485), and circuits where polarity cannot be guaranteed during installation or operation.
Is P6SMB160CAHM3_A/I suitable for automotive applications?
Yes - P6SMB160CAHM3_A/I carries the HM3 suffix, confirming it is halogen-free, RoHS-compliant, and AEC-Q101 qualified. It has passed rigorous automotive stress tests including temperature cycling, humidity bias, and mechanical shock, making P6SMB160CAHM3_A/I appropriate for engine control units, ADAS sensors, and body electronics in passenger vehicles and commercial vehicles.
What is the maximum clamping voltage of P6SMB160CAHM3_A/I and under what conditions is it specified?
The maximum clamping voltage (VC) of P6SMB160CAHM3_A/I is 219 V, measured at a peak pulse current (IPPM) of 2.7 A using the standard 10/1000 μs double-exponential waveform. This value is guaranteed across the full operating temperature range (−65 °C to +150 °C) and defines the highest voltage that will appear across protected circuitry during a surge event.
How does the SMB (DO-214AA) package of P6SMB160CAHM3_A/I compare to larger packages like SMC (DO-214AB)?
The SMB package of P6SMB160CAHM3_A/I measures 4.57 mm × 3.94 mm × 2.20 mm - significantly smaller than SMC (7.11 mm × 6.22 mm × 2.62 mm). While both deliver 600 W peak power, P6SMB160CAHM3_A/I achieves higher power density and fits tighter layouts, though its RθJA (100 °C/W) is lower than SMC's typical 60–70 °C/W, requiring attention to pad area for thermal management.
Does P6SMB160CAHM3_A/I require orientation during PCB placement?
No - P6SMB160CAHM3_A/I is a bidirectional TVS with no polarity marking on the SMB package. Both terminals are functionally identical, eliminating orientation constraints during automated placement. This simplifies manufacturing, reduces assembly errors, and supports flexible routing in differential or floating signal paths where polarity assignment is undefined.
