Product details
Overview
P6SMB200C from Taiwan Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal interfaces. It features a 200V breakdown voltage (VBR min/max = 180–220V), 600W peak pulse power rating (10/1000μs), clamping voltage of 287V at 2.1A peak pulse current, and operates across –55°C to +150°C junction temperature. It is used in industrial power supplies and automotive infotainment systems to protect downstream ICs from ESD and load-dump transients.
For engineers reviewing the P6SMB200C datasheet, P6SMB200C pinout, P6SMB200C application, or P6SMB200C equivalent, key selection criteria include its bidirectional configuration (C suffix), DO-214AA (SMB) package compatibility with automated SMT assembly, low leakage (<1μA @ 162V), and ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance for automotive-grade surge immunity.
Technical Context
The P6SMB200C implements a glass-passivated silicon avalanche junction optimized for fast transient response (<1.0ps rise time from 0V to VBR), enabling effective suppression of sub-nanosecond ESD events. Its unidirectional counterpart uses an anode/cathode polarity marking, while the C-suffix variant provides symmetrical clamping in both directions - critical for AC-coupled or floating-bus applications like CAN FD data lines or sensor bridges.
Thermally, it delivers RθJC = 10°C/W and RθJA = 55°C/W, supporting sustained operation at 3W steady-state dissipation when PCB copper area meets JEDEC 2s2p layout guidelines. The device's 0.090g mass and UL 94V-0 molding compound ensure reliability under thermal cycling and flammability requirements in enclosed power adapters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 180V / 220V - defines minimum and maximum voltage at which avalanche conduction begins under 1mA test current; ensures consistent clamping across production lot |
| VWM | 162V - maximum continuous reverse operating voltage; must exceed system DC rail by ≥10% to prevent leakage-induced power loss |
| VC @ IPPM | 287V @ 2.1A - clamped voltage during 10/1000μs surge; determines maximum stress on protected IC's absolute maximum rating |
| PPPSM | 600W - non-repetitive peak pulse power handling; validates robustness against ISO 7637-2 Pulse 5a (load dump) events |
| IR @ VWM | <1μA - reverse leakage at stand-off voltage; enables low-quiescent-current designs in battery-powered sensors |
| TJ max | +150°C - maximum junction temperature; supports operation in under-hood automotive environments without derating |
| Package | DO-214AA (SMB) - industry-standard surface-mount outline with 4.58mm × 3.94mm footprint and gull-wing leads for reflow compatibility |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with matte tin-plated leads, polarity indicated by cathode band (bidirectional symmetry means band denotes reference terminal, not polarity). Weight: 0.090g. Meets JESD201 Class 2 whisker resistance and J-STD-020 moisture sensitivity Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction terminals | Either terminal serves as input/output; no DC bias dependency - ideal for AC signal line protection (e.g., RS-485, CAN) |
| Cathode band marking | Reference terminal indicator | Provides mechanical orientation for automated placement; does not imply unidirectional function in C-suffix parts |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance (±5% for A-grade variants) and long-term reliability under humidity exposure per J-STD-020 |
| ISO 7637-2 compliance | Validated for Pulse 1 (inductive switch-off), Pulse 2a/2b (battery disconnection), and Pulse 3a/3b (capacitive coupling) - required for automotive ECUs |
| Fast response time | <1.0ps from 0V to VBR min - limits voltage overshoot during nanosecond ESD strikes (IEC 61000-4-2 Level 4) |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU - supports green manufacturing and end-of-life recycling |
| Automated placement ready | Low-profile SMB body (2.6mm height) and J-STD-002 solderable leads enable >99.9% placement yield on high-speed pick-and-place machines |
Applications
| Industrial Power Supply Protection | Automotive Infotainment Interface |

IC Role / Device Role / Timing Role: Common-mode TVS on bus lines referenced to earth ground, paired with differential receivers. Use Value: Symmetrical clamping (±287V) prevents common-mode voltage excursion beyond transceiver common-mode range (–7V to +12V), eliminating false data errors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | Same DO-214AA package and 200V VBR, but higher 600W rating achieved via tighter VBR tolerance (5% vs. P6SMB200C's 10%) and lower VC (274V @ 2.2A) | Preferred where tighter clamping consistency is required across temperature (–55°C to +150°C) and lifetime | Select SMBJ200CA if design requires guaranteed VC ≤275V under worst-case surge conditions |
| 1.5KE200CA | Higher 1500W rating but axial DO-15 package; larger footprint, manual assembly only; VBR 180–220V same, but VC = 328V @ 4.6A | Suitable for prototyping or low-volume industrial controls where board space and automation are not constraints | Choose 1.5KE200CA only for through-hole legacy designs or when 1500W surge margin is mandatory |
Compared with SMBJ200CA and 1.5KE200CA, the P6SMB200C offers optimal balance of SMT manufacturability, 600W surge capability, and cost for high-volume automotive and industrial power applications - without requiring PCB redesign or sacrificing clamping performance.

FAQ
What is the polarity configuration of the P6SMB200C?
The P6SMB200C is a bidirectional TVS diode, denoted by the "C" suffix. Its symmetrical avalanche structure allows identical clamping behavior in both forward and reverse directions - making it suitable for AC signal lines, differential buses, or floating grounds where polarity cannot be assumed. Unlike unidirectional variants (e.g., P6SMB200A), no anode/cathode distinction governs circuit function.
Does the P6SMB200C meet automotive surge standards?
Yes, the P6SMB200C meets ISO 7637-2 Pulse 1 (inductive load dump), Pulse 2a/2b (battery disconnection), and Pulse 3a/3b (capacitive coupling) requirements. Its 600W peak pulse power rating, 287V clamping voltage at 2.1A, and –55°C to +150°C operating range align with AEC-Q200 stress test profiles for transient suppression in automotive ECUs and infotainment modules.
What is the maximum clamping voltage of the P6SMB200C under surge conditions?
The maximum clamping voltage (VC) of the P6SMB200C is 287V at a peak pulse current (IPPM) of 2.1A with a 10/1000μs waveform. This value is measured per ANSI/IEEE C62.35 and represents the upper limit of voltage imposed on protected circuitry during standardized surge events - critical for verifying compatibility with downstream ICs' absolute maximum ratings.
Can the P6SMB200C replace the P6SMB200A in a design?
No - the P6SMB200C and P6SMB200A are not interchangeable without validation. The P6SMB200A is unidirectional (anode/cathode), while the P6SMB200C is bidirectional. Substituting one for the other may cause incorrect clamping behavior on AC-coupled or floating nodes. Always verify circuit topology and grounding scheme before replacement; the "C" and "A" suffixes denote fundamentally different electrical configurations.
What is the junction capacitance of the P6SMB200C at zero bias?
The junction capacitance (CJ) of the P6SMB200C is less than 100pF at 0V bias, measured at 1.0MHz with 50mVp-p signal amplitude. This low capacitance preserves signal integrity on high-speed data lines such as RS-485 or CAN FD, minimizing rise-time degradation and reflection-induced jitter - confirmed in TSC's Characteristic Curves Figure 5.
