Product details
Overview
P6SMB160CAHE3_B/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 (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6SMB160CAHE3_B/I datasheet, P6SMB160CAHE3_B/I pinout, P6SMB160CAHE3_B/I application, or P6SMB160CAHE3_B/I equivalent, this device is selected for robust ESD and surge protection where bidirectional clamping, AEC-Q101 qualification, and SMB (DO-214AA) package compatibility are required in automotive and industrial designs.
Technical Context
The P6SMB160CAHE3_B/I operates as a bidirectional avalanche diode, symmetrically clamping both positive and negative transients without polarity dependence. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 μA at VWM), while its thermal resistance (RθJA = 100 °C/W) supports operation up to TJ = 150 °C under defined PCB pad conditions (0.2" × 0.2" copper).
It delivers 600 W peak pulse power per 10/1000 μs waveform at TA = 25 °C, derating linearly above 25 °C per Fig. 2. The device meets MSL Level 1 per J-STD-020 and is qualified to AEC-Q101, confirming suitability for automotive electronics environments requiring high-reliability transient suppression.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse voltage before clamping begins; defines safe operating window for protected circuitry. |
| VBR (Breakdown Voltage) | 152–168 V at IT = 1.0 mA - Confirmed avalanche initiation range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 219 V at IPPM = 2.7 A - Peak voltage seen by downstream components during 600 W transient; critical for IC survivability. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability with 10/1000 μs waveform; enables protection against IEC 61000-4-5 Level 4 surges. |
| ID (Reverse Leakage) | ≤1.0 μA at VWM - Minimal standby current; avoids loading sensitive analog or low-power circuits. |
| TJ max. | 150 °C - Maximum junction temperature; supports operation in under-hood automotive or enclosed industrial enclosures. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 0.220" × 0.130" footprint; compatible with automated pick-and-place and reflow. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional - no polarity marking; symmetrical terminal configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Both terminals function identically; conducts during either polarity excursion above VBR - no orientation required during placement. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for engine control and ADAS power rails. |
| 600 W peak pulse power | Withstands 10/1000 μs surges up to 2.7 A without degradation - meets IEC 61000-4-5 surge immunity requirements for industrial equipment. |
| Glass passivated junction | Ensures stable VBR tolerance and low leakage drift over time and temperature - critical for long-life embedded systems. |
| MSL Level 1 rating | Compatible with standard SMT reflow profiles up to 260 °C peak - eliminates moisture sensitivity concerns and pre-bake steps. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage stress on protected devices - improves margin for 150 V-rated MOSFETs or 200 V bus capacitors. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V power distribution networks in body control modules from load dump and ISO 7637-2 transients. IC Role / Device Role / Timing Role: Bidirectional TVS clamping element placed at power entry point before DC-DC converters and microcontrollers.

Use Scenario: Clamping input rectifier output in universal-input AC/DC adapters to prevent overvoltage during MOV failure or brownout recovery. IC Role / Device Role / Timing Role: Secondary-stage TVS across bulk capacitor terminals, triggered after primary MOV clamping. Use Value: Provides redundant protection with 136 V VWM - avoids false triggering during 115/230 VAC line variations while blocking >219 V faults. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage 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; unsuitable for IEC 61000-4-5 Level 4 or automotive load dump | Select when board space is constrained and surge energy is ≤400 W; verify thermal margin with smaller pads. |
| SMCJ160CA | Same VWM (136 V), higher PPPM (1500 W), larger SMC (DO-214AB) package (lower RθJA = 50 °C/W) | Supports higher surge repetition rates and longer pulse durations; requires larger PCB area | Choose for mission-critical industrial drives or solar inverters needing >1 kW surge handling and improved thermal dissipation. |

FAQ
What is the clamping voltage of P6SMB160CAHE3_B/I at its rated peak pulse current?
The P6SMB160CAHE3_B/I has a maximum clamping voltage (VC) of 219 V at its specified peak pulse current (IPPM) of 2.7 A, measured using a 10/1000 μs waveform. This value is guaranteed per the Vishay datasheet (Doc. #88370, Rev. 09-Jan-2024) and defines the upper voltage limit imposed on protected circuitry during surge events. Designers use this parameter to verify that downstream components remain within their absolute maximum ratings.
Is P6SMB160CAHE3_B/I unidirectional or bidirectional, and how does that affect PCB layout?
P6SMB160CAHE3_B/I is a bidirectional TVS diode, indicated by the "CA" suffix and confirmed in the Vishay datasheet. It has no polarity marking and functions identically in both directions - meaning either terminal can connect to the line being protected without regard to signal or supply polarity. This simplifies PCB layout by eliminating orientation checks during automated assembly and enables use on AC-coupled or differential lines without additional design constraints.
Does P6SMB160CAHE3_B/I meet automotive qualification standards?
Yes, P6SMB160CAHE3_B/I is AEC-Q101 qualified, as confirmed by the "HE3_B" suffix and documentation in Vishay's P6SMB series datasheet (Rev. 09-Jan-2024). This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD, validating its reliability for automotive applications such as body control modules, infotainment power supplies, and ADAS sensor interfaces - provided thermal design adheres to the recommended 0.2" × 0.2" copper pad layout.
What is the maximum operating junction temperature for P6SMB160CAHE3_B/I?
The maximum operating junction temperature (TJ max.) for P6SMB160CAHE3_B/I is +150 °C, as specified in the Vishay P6SMB datasheet (Document Number: 88370). This rating applies under defined thermal conditions - specifically, when mounted on 0.2" × 0.2" copper pads per terminal. Exceeding this temperature risks parametric shift or permanent degradation; designers must perform thermal analysis using RθJA = 100 °C/W and ambient conditions to ensure safe operation.
How does the "_B/I" suffix in P6SMB160CAHE3_B/I impact packaging and ordering?
The "_B/I" suffix in P6SMB160CAHE3_B/I indicates two key attributes: "B" denotes AEC-Q101 qualification for the P6SMB6.8(C)A–P6SMB220(C)A voltage range, and "I" specifies packaging in 13-inch diameter plastic tape and reel with a base quantity of 3200 units. This format supports high-volume SMT production and ensures traceability for automotive and industrial customers requiring full lot-level documentation and compliance reporting.
