Product details
Overview
P6SMB110CA from Taiwan Semiconductor is a bidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a standoff voltage of 89.2V, breakdown voltage range 99–121V, and clamping voltage of 158V at 3.9A peak pulse current. It protects DC power rails in switching mode power supplies, adapters, and display electronics against ESD and surge events per ISO 7637-2 Pulse 1/2a/2b/3a/3b.
For engineers reviewing the P6SMB110CA datasheet, P6SMB110CA pinout, P6SMB110CA application, or P6SMB110CA equivalent, key selection criteria include bidirectional clamping capability, DO-214AA (SMB) package compatibility, 150°C junction rating, <1μA leakage at 89.2V, and fast sub-1ps response to transients.
Technical Context
The P6SMB110CA is a glass-passivated, bipolar junction TVS diode designed for unidirectional or bidirectional surge suppression in DC circuits. Its symmetrical I-V characteristics enable identical clamping in both polarities, with a typical junction capacitance below 100pF at 0V and <50pF at VWM, supporting high-speed signal integrity in power rail protection.
Thermal performance is defined by RθJC = 10°C/W and RθJA = 55°C/W, enabling reliable operation up to 150°C junction temperature. It meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1, supporting lead-free reflow assembly without preconditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 89.2 V - Maximum continuous reverse operating voltage before significant leakage begins; sets upper limit for protected line voltage. |
| VBR (min/max) | 99 V / 121 V - Breakdown occurs within this range at 1mA test current; defines threshold for clamping activation. |
| VC @ IPPM | 158 V at 3.9 A - Maximum clamped voltage during 10/1000μs surge; determines worst-case overvoltage seen by downstream circuitry. |
| PPPSM | 600 W - Peak pulse power handling per 10/1000μs waveform; defines surge energy absorption capacity. |
| IR @ VWM | <1 μA - Reverse leakage at rated standoff voltage; ensures minimal power loss and no false triggering in low-power systems. |
| TJ max | 150 °C - Maximum allowable junction temperature; supports operation in high-ambient industrial environments. |
| Response time | <1.0 ps - Time from 0V to VBR(min); enables suppression of ultrafast ESD and lightning-induced transients. |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, bi-directional configuration with cathode band omitted (symmetrical terminals). Matte tin-plated leads, UL 94V-0 molding compound, 0.090g weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Transient current entry point in negative polarity | Accepts reverse surge current during negative-going transients; electrically identical to Cathode under bidirectional operation. |
| Cathode (K) | Transient current entry point in positive polarity | Accepts reverse surge current during positive-going transients; functionally interchangeable with Anode due to CA symmetry. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR, VC, and IPPM in both directions - eliminates polarity concerns in AC-coupled or floating DC bus protection. |
| Glass passivated junction | Enhanced reliability and stable leakage performance across temperature and humidity - critical for long-life industrial power supplies. |
| ISO 7637-2 compliance | Validated for automotive-grade surge immunity (Pulse 1/2a/2b/3a/3b) - suitable for 12V/24V vehicle subsystems and industrial control inputs. |
| Moisture sensitivity level 1 | No bake requirement prior to reflow - reduces manufacturing overhead and avoids thermal stress on PCB assemblies. |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive - supports environmental compliance for global OEM shipments. |
Applications
| Switching Mode Power Supply (SMPS) | AC-DC Adapter |
|---|---|
Use Scenario: Input rectifier output and DC bus lines subject to load dump, inductive kickback, and ESD coupling. IC Role / Device Role / Timing Role: Primary overvoltage clamp protecting MOSFETs, controllers, and bulk capacitors from 600W transient energy. Use Value: Limits voltage excursion to ≤158V during 10/1000μs surges, preventing gate oxide rupture and capacitor overvoltage failure. | Use Scenario: Secondary-side DC output rails exposed to user-port ESD and cable discharge events. IC Role / Device Role / Timing Role: Bidirectional transient shunt placed directly across +VOUT/GND to suppress ±8kV contact ESD per IEC 61000-4-2. Use Value: Sub-1ps response and <1μA leakage ensure no impact on regulation accuracy while guaranteeing fail-safe clamping. |
| Television Power Board | Monitor Backlight Inverter |
Use Scenario: Main 12V/24V logic and audio supply rails encountering conducted noise from internal switching stages. IC Role / Device Role / Timing Role: Localized TVS at point-of-load near microcontrollers and audio amplifiers. Use Value: 89.2V VWM allows safe operation above nominal rail while clamping transients to 158V - preserving signal integrity and latch-up immunity. | Use Scenario: High-voltage CCFL or LED driver input lines susceptible to flyback spikes and hot-plug transients. IC Role / Device Role / Timing Role: Front-end surge limiter on inverter primary side before transformer isolation. Use Value: 600W PPPSM rating absorbs repetitive 100ns–1μs spikes without degradation, extending inverter lifetime in commercial displays. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | Same DO-214AA package, identical VWM/VBR/VC, but rated at 600W with tighter VBR tolerance (±5% vs ±10% for P6SMB110CA). | Preferred where tighter voltage matching is required across production lots; otherwise functionally interchangeable. | Select SMBJ110CA when statistical process control demands tighter parametric consistency in high-volume SMPS designs. |
| 1.5KE110CA | Higher 1500W rating, axial DO-15 package - larger footprint, higher inductance, not surface-mount compatible. | Suitable only for through-hole prototyping or legacy board refreshes; incompatible with automated SMT assembly. | Choose 1.5KE110CA only if existing PCB layout prohibits DO-214AA and surge energy exceeds 600W margin. |
Compared with SMBJ110CA and 1.5KE110CA, the P6SMB110CA offers optimal balance of SMT manufacturability, ISO 7637-2 compliance, and cost-effective 600W protection - making it the preferred choice for new-generation compact power modules and display electronics.

FAQ
What is the maximum clamping voltage of the P6SMB110CA under standard 10/1000μs surge conditions?
The P6SMB110CA has a maximum clamping voltage (VC) of 158 V when subjected to its rated peak pulse current of 3.9 A using the standardized 10/1000μs waveform. This value is measured at TA = 25°C and guarantees that downstream components experience no more than 158 V during transient events, provided layout inductance is minimized per DO-214AA footprint guidelines.
Does the P6SMB110CA require polarity-aware PCB placement?
No - the P6SMB110CA is a bidirectional TVS diode denoted by the "CA" suffix, meaning its anode and cathode terminals exhibit identical electrical behavior in both forward and reverse bias. The device lacks a cathode band marking and may be mounted in either orientation on the PCB without affecting clamping performance or reliability.
What is the junction-to-ambient thermal resistance (RθJA) of the P6SMB110CA in standard JEDEC high-K board conditions?
The P6SMB110CA has a specified junction-to-ambient thermal resistance (RθJA) of 55°C/W under standard JEDEC Test Method JESD51-2 conditions (single-layer 1 in² copper pad). This value assumes no additional copper pour or thermal vias; actual board-level RθJA can improve to ≤35°C/W with optimized thermal land design per TSC's recommended pad layout.
Is the P6SMB110CA compliant with automotive surge immunity standards?
Yes - the P6SMB110CA is explicitly tested and compliant with ISO 7637-2 for automotive transient immunity, covering Pulse 1 (inductive load disconnect), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling). Its 600W rating and sub-1ps response meet requirements for 12V and 24V vehicle subsystems including infotainment power rails and display modules.
What is the maximum steady-state power dissipation (Ptot) of the P6SMB110CA at 25°C ambient?
The P6SMB110CA has a maximum steady-state power dissipation (Ptot) of 3 W at TA = 25°C, as defined in its Absolute Maximum Ratings table. This rating applies only to continuous DC or low-frequency reverse-bias conditions - transient suppression operates in non-dissipative avalanche mode and does not contribute to steady-state thermal load.
