Product details
Overview
P6SMB160CA-E3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, rated for 160 V standoff voltage (VWM), 179 V minimum breakdown voltage (VBR), and 600 W peak pulse power (10/1000 μs). It clamps transients to ≤219 V at 2.7 A peak pulse current and operates across –65 °C to +150 °C junction temperature, protecting signal lines in automotive sensor units and industrial I/O interfaces.
For engineers reviewing the P6SMB160CA-E3/52 datasheet, P6SMB160CA-E3/52 pinout, P6SMB160CA-E3/52 application, or P6SMB160CA-E3/52 equivalent, key selection criteria include bidirectional clamping capability, RoHS-compliant matte tin terminals, MSL Level 1 moisture sensitivity, and AEC-Q101 qualification eligibility via HE3/HM3 suffix variants - all critical for high-reliability board-level ESD and surge protection design.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ps) and low incremental surge resistance, enabling effective suppression of inductive switching spikes and lightning-induced transients on bidirectional data or power rails. Its symmetrical clamping behavior ensures identical protection in both polarities without polarity marking.
The device is characterized with a 10/1000 μs double-exponential waveform per REA standards, derated above 25 °C ambient using a 100 °C/W junction-to-ambient thermal resistance. Mounting on 0.2" × 0.2" copper pads is required to sustain full 600 W pulse rating per JEDEC test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 136 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below system rail. |
| VBR (Breakdown, min) | 179 V at 1 mA - Guaranteed minimum voltage at which avalanche conduction initiates; ensures predictable turn-on threshold. |
| VC (Clamping, max) | 219 V at 2.7 A IPPM - Peak voltage seen by protected circuit during 600 W transient; determines stress on downstream components. |
| PPPM | 600 W (10/1000 μs) - Sustains single high-energy surges common in automotive load-dump or industrial relay switching events. |
| IR (Leakage, max) | 1.0 μA at 136 V - Negligible standby current; avoids signal integrity degradation or battery drain in always-on circuits. |
| TJ Range | –65 °C to +150 °C - Supports operation in under-hood automotive, factory-floor, and outdoor telecom environments. |
| Package | SMB (DO-214AA) - Surface-mount footprint compatible with automated placement; 5.59 mm × 4.06 mm body with 2.18 mm min. cathode band spacing. |

Applications
| Automotive Sensor Interface Protection | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) from load-dump spikes and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed directly at connector entry point to shunt transients before reaching sensitive IC inputs. Use Value: Prevents latch-up or permanent damage to 3.3 V/5 V interface ICs while maintaining signal fidelity due to sub-1 μA leakage at 136 V standoff. |
Use Scenario: Safeguarding 4–20 mA current-loop inputs and ±10 V analog inputs in programmable logic controllers against field-wiring induced surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on differential input pairs, working in concert with series current-limiting resistors and filtering capacitors. Use Value: Enables robust operation in harsh factory environments where 600 W transient immunity exceeds EN 61000-4-4 (EFT) and IEC 61000-4-5 requirements. |
| Telecom Line Card Surge Protection | Consumer Appliance Motor Drive Protection |
Use Scenario: Shielding Ethernet PHYs, DSL line drivers, and PoE injectors from lightning-induced surges entering via RJ-45 jacks or external cabling. IC Role / Device Role / Timing Role: First-stage clamping device on unshielded twisted-pair lines, coordinated with gas discharge tubes (GDTs) for staged protection. Use Value: Fast <1 ps response captures initial surge edge before GDT fires, reducing let-through energy to <100 mJ at 219 V clamping voltage. |
Use Scenario: Suppressing back-EMF spikes generated by brushed DC motors and solenoids in washing machines, HVAC actuators, and power tools. IC Role / Device Role / Timing Role: Snubber element across motor terminals or relay coils, diverting inductive kickback away from microcontroller GPIOs and driver ICs. Use Value: Eliminates need for discrete RC snubbers; 136 V standoff allows use with 120 VAC rectified rails while clamping to 219 V to protect 250 V-rated MOSFETs. |
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 SMB package, 160 V VWM, but rated for 600 W with tighter VBR tolerance (179–188 V vs. 179–197 V); lower RθJA (85 °C/W). | Preferred where tighter clamping consistency and improved thermal performance are required in space-constrained designs. | Select SMBJ160CA when board layout allows optimized thermal pad design and tighter VC variation is critical for downstream component margin. |
| 1.5SMC160CA | Larger SMC (DO-214AB) package; same 160 V VWM and 600 W rating, but higher IPPM (3.1 A) and lower VC (212 V); RθJA = 65 °C/W. | Better suited for high-repetition-rate surge environments (e.g., motor drives with frequent commutation) due to superior thermal dissipation. | Choose 1.5SMC160CA when PCB real estate permits larger footprint and sustained surge duty cycle exceeds 0.01%. |
Compared with P6SMB160CA-E3/52, SMBJ160CA offers tighter parametric control and better thermal efficiency in the same footprint, while 1.5SMC160CA trades size for higher surge endurance and lower clamping voltage - making each optimal for distinct thermal, layout, and reliability priorities.

FAQ
What is the maximum clamping voltage of the P6SMB160CA-E3/52 under peak pulse conditions?
The P6SMB160CA-E3/52 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 per REA-defined test conditions and represents the highest voltage the protected circuit will experience during a full-rated 600 W transient event. The P6SMB160CA-E3/52 maintains this clamping performance across its full operating temperature range.
Is the P6SMB160CA-E3/52 suitable for automotive applications?
The P6SMB160CA-E3/52 itself is RoHS-compliant and commercial-grade; however, Vishay offers AEC-Q101 qualified variants under ordering codes like P6SMB160CAHE3_B/H. These HE3/HM3 suffix versions undergo rigorous stress testing for automotive use. For non-automotive designs, the P6SMB160CA-E3/52 delivers proven surge robustness in industrial and telecom systems where AEC-Q101 is not mandated.
How does the bidirectional configuration of the P6SMB160CA-E3/52 affect PCB layout?
The P6SMB160CA-E3/52 has no polarity marking and functions identically in both directions, simplifying PCB layout by eliminating orientation constraints during automated placement. Unlike unidirectional TVS diodes, it requires no cathode band alignment - reducing assembly errors and enabling symmetric routing on differential lines or AC-coupled paths. This symmetry is especially valuable in Ethernet, RS-485, and audio interface protection.
What is the thermal resistance specification for the P6SMB160CA-E3/52?
The P6SMB160CA-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" copper pads per terminal. Its junction-to-lead resistance (RθJL) is 20 °C/W, indicating efficient heat transfer to PCB copper. These values assume JEDEC-standard test conditions and must be validated in actual board layouts with thermal vias and ground plane coverage.
Does the P6SMB160CA-E3/52 require derating at elevated ambient temperatures?
Yes - the P6SMB160CA-E3/52 must be derated above 25 °C ambient per Figure 2 in the Vishay datasheet (Document Number 88370). At 85 °C ambient, its 600 W peak pulse power rating drops to approximately 420 W, and at 125 °C, it falls to ~240 W. Derating curves are based on thermal resistance and junction temperature limits (TJ ≤ 150 °C), so proper PCB copper area and airflow must be verified for high-temperature deployments.
