Product details
Overview
P6SMB160CA-M3/5B 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), 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 capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB160CA-M3/5B datasheet, P6SMB160CA-M3/5B pinout, P6SMB160CA-M3/5B application, or P6SMB160CA-M3/5B equivalent, key selection criteria include bidirectional clamping performance, SMB (DO-214AA) package compatibility, halogen-free RoHS compliance (M3 suffix), AEC-Q101 qualification readiness, and thermal resistance (RθJA = 100 °C/W) under standard PCB pad layout.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal lines without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the low incremental surge resistance supports fast transient suppression with minimal voltage overshoot.
The device is rated for repetitive 10/1000 μs pulses at 0.01 % duty cycle and derates linearly above 25 °C ambient, with maximum junction temperature of +150 °C. Mounting on 0.2" × 0.2" copper pads per terminal is required to achieve specified PPPM and thermal performance.
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 1.0 mA test current - Ensures reliable triggering within tight tolerance band for predictable protection onset. |
| VC (Clamping Voltage) | 219 V at IPPM = 2.7 A - Peak voltage seen by protected circuit during worst-case transient; critical for downstream component survivability. |
| PPPM (Peak Pulse Power) | 600 W with 10/1000 μs waveform - Sustains high-energy surges common in inductive switching and lightning-induced transients. |
| ID (Reverse Leakage) | ≤1.0 μA at VWM - Minimizes standby power loss and avoids false triggering in low-power sensor or battery-backed systems. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient; requires defined 0.2" × 0.2" copper pad layout to meet datasheet ratings. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 2.2 mm height and 3.94 mm length; compatible with automated pick-and-place. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Cathode/anode terminals are symmetrical; both ends function identically under reverse or forward bias during transient events.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Both terminals serve as interchangeable surge current entry/exit points; no directional marking required for bidirectional operation. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., RS-485), and floating power rails without external polarity management. |
| 600 W peak pulse power | Withstands IEC 61000-4-5 Level 4 surge events (4 kV/2 Ω) when properly mounted, reducing need for cascaded protection stages. |
| Halogen-free, RoHS-compliant (M3) | Meets environmental compliance requirements for automotive and industrial end equipment without compromising surge robustness. |
| AEC-Q101 qualification option | Base part supports automotive-grade variants (e.g., P6SMB160CAHM3_B); this M3/5B variant is qualified-ready with documented reliability testing path. |
| Low-profile SMB package | Height ≤2.2 mm enables use in space-constrained modules such as automotive ECUs, IoT sensor nodes, and portable instrumentation. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

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/VBR/VC specs but in smaller SMA (DO-214AC) package; RθJA = 140 °C/W; lower PPPM (400 W). | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 without derating or parallel devices. | Select when board space is constrained and surge energy is ≤400 W; verify thermal margin with reduced copper area. |
| SMCJ160CA | Same VWM/VBR/VC but in larger SMC (DO-214AB) package; PPPM = 1500 W; RθJA = 50 °C/W. | Supports higher-repetition surges and longer-duration transients; requires 30% more PCB area than SMB. | Choose for mission-critical industrial drives or EV charging where sustained 1500 W surge handling and lower thermal resistance are mandatory. |
Compared with SMAJ160CA and SMCJ160CA, P6SMB160CA-M3/5B delivers optimal balance of 600 W surge capacity, SMB footprint efficiency, and halogen-free compliance - making it ideal for cost-sensitive, space-limited automotive and industrial designs requiring verified AEC-Q101 qualification path.

FAQ
What is the clamping voltage of P6SMB160CA-M3/5B at its rated peak pulse current?
The P6SMB160CA-M3/5B has a maximum clamping voltage (VC) of 219 V at a peak pulse current (IPPM) of 2.7 A with a 10/1000 μs waveform. This value is measured under standardized test conditions with the device mounted on 0.2" × 0.2" copper pads per terminal, and it represents the upper voltage limit imposed on protected circuitry during surge events.
Is P6SMB160CA-M3/5B suitable for automotive applications?
Yes - P6SMB160CA-M3/5B is halogen-free and RoHS-compliant, and belongs to the AEC-Q101-qualified P6SMB family. While the M3/5B variant itself carries the qualification-ready M3 suffix, automotive-grade versions (e.g., P6SMB160CAHM3_B) are explicitly certified. Designers may use P6SMB160CA-M3/5B in automotive systems with appropriate reliability validation per their internal process.
How does the bidirectional nature of P6SMB160CA-M3/5B affect its placement on the PCB?
P6SMB160CA-M3/5B has no polarity marking and functions identically in both directions, so orientation on the PCB is not critical. It can be placed across any two nodes requiring symmetrical overvoltage protection - such as differential signal lines, AC power inputs, or floating supply rails - without concern for anode/cathode alignment.
What is the thermal resistance of P6SMB160CA-M3/5B, and how does it impact layout?
The P6SMB160CA-M3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W, measured with 0.2" × 0.2" copper pads per terminal. To maintain rated 600 W pulse power, PCB layout must replicate this pad size and avoid excessive trace narrowing or thermal isolation that would increase actual RθJA and risk junction overheating.
Does P6SMB160CA-M3/5B require derating at elevated ambient temperatures?
Yes - P6SMB160CA-M3/5B must be derated above TA = 25 °C per Figure 2 in the Vishay datasheet (Document Number: 88370). At 85 °C ambient, its peak pulse power capability drops to approximately 420 W (70 % of 600 W), and at 125 °C, it falls to ~240 W (40 %), ensuring safe operation within the -65 °C to +150 °C junction temperature range.
