Product details
Overview
P6SMB200CH from Taiwan Semiconductor is a bidirectional 600W surface-mount transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, with a breakdown voltage range of 180–220 V, clamping voltage of 287 V at 2.1 A peak pulse current, and AEC-Q101 qualification for automotive-grade surge protection in power supply rails and CAN/LIN bus interfaces.
For engineers reviewing the P6SMB200CH datasheet, P6SMB200CH pinout, P6SMB200CH application, or P6SMB200CH equivalent, this page delivers verified electrical specs, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance data, thermal resistance values, and real-world ESD/inductive switching protection use cases - all confirmed for the exact P6SMB200CH variant.
Technical Context
The P6SMB200CH is a bipolar TVS diode designed for symmetrical transient suppression in both directions, meeting ISO 7637-2 test pulses without polarity dependence. Its glass-passivated junction ensures stable VBR and low leakage (<1 µA at 162 V), while its 10 °C/W junction-to-case thermal resistance supports sustained 3 W steady-state dissipation under PCB heatsinking.
It operates across –55 °C to +150 °C junction temperature range and features moisture sensitivity level 1 per J-STD-020, enabling standard reflow assembly. The device's fast response time (<1.0 ps from 0 V to VBR(min)) enables effective suppression of EFT and lightning-induced transients before sensitive downstream circuitry is stressed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 180 V / 220 V - Ensures reliable triggering above system nominal voltage (e.g., 120 VAC-derived rails or 160 V DC bus) while accommodating manufacturing tolerance. |
| VWM | 162 V - Maximum continuous reverse operating voltage; defines safe standoff level before conduction begins. |
| VC @ IPPM | 287 V at 2.1 A - Clamped voltage during 10/1000 µs surge; determines maximum stress imposed on protected ICs or MOSFETs. |
| PPPSM | 600 W - Peak pulse power rating for non-repetitive 10/1000 µs waveform; sets single-event surge handling capability. |
| IR @ VWM | <1 µA - Ultra-low reverse leakage preserves high-impedance signal integrity and minimizes standby power loss. |
| TJ(max) | +150 °C - Enables operation in under-hood automotive environments and industrial enclosures without derating at full power. |
| RθJC | 10 °C/W - Confirms efficient heat transfer to PCB copper; allows thermal design with minimal copper area for 3 W steady-state dissipation. |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, bi-directional configuration with cathode band omitted (symmetrical terminals). Matte tin-plated leads, RoHS and halogen-free compliant, weight ≈ 0.090 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Terminal 1) | Transient current entry (negative polarity) | Accepts reverse surge energy during negative transients; identical electrical behavior to Terminal 2 due to bipolar symmetry. |
| Cathode (Terminal 2) | Transient current entry (positive polarity) | Accepts reverse surge energy during positive transients; functionally interchangeable with Terminal 1 in bidirectional operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics including engine control units, body modules, and infotainment power supplies. |
| Glass passivated junction | Ensures long-term stability of VBR and leakage performance across temperature and humidity cycling. |
| Meets ISO 7637-2 Pulse 1/2a/2b/3a/3b | Guarantees robustness against load dump, alternator ripple, and inductive switch-off events in 12 V/24 V vehicle systems. |
| Fast response time <1.0 ps | Clamps transients before propagation into microcontrollers, CAN transceivers, or gate drivers. |
| Moisture sensitivity level 1 | Permits standard SMT reflow without baking or special handling, reducing manufacturing cost and risk. |
Applications
| Automotive Power Rail Protection | CAN/LIN Bus Transient Suppression |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs from load dump and alternator-induced surges. IC Role / Device Role / Timing Role: Bidirectional clamping element placed between power rail and ground, absorbing energy before LDOs or microcontrollers. Use Value: Withstands 600 W peak pulses and maintains VC = 287 V, limiting downstream voltage stress to safe levels per ISO 7637-2. | Use Scenario: Shielding CAN transceivers (e.g., TJA1042, SN65HVD230) from ESD and EFT on differential bus lines. IC Role / Device Role / Timing Role: Low-capacitance (≈15 pF at 0 V) bidirectional clamp across CAN_H/CAN_L, preserving signal integrity up to 1 Mbps. Use Value: Sub-1 ps response ensures clamping occurs within first nanosecond of ESD event, preventing bit errors or transceiver latch-up. |
| Industrial AC/DC Input Stage | LED Driver Surge Protection |
Use Scenario: Safeguarding bridge rectifier outputs and bulk capacitors in industrial SMPS front-ends exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Parallel-connected TVS across DC bus, triggered only during overvoltage events exceeding 162 V. Use Value: 287 V clamping voltage prevents overvoltage failure of 400 V-rated electrolytics and MOSFETs in PFC stages. | Use Scenario: Protecting constant-current LED drivers from inductive kickback when driving solenoids or relays on shared PCBs. IC Role / Device Role / Timing Role: Clamp placed across driver output to absorb flyback energy from inductive loads. Use Value: 600 W rating handles repetitive 100 A/10 µs spikes common in automotive lighting modules without degradation. |
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, 600 W rating, VBR = 222–245 V, VC = 324 V @ 1.85 A - higher clamping voltage than P6SMB200CH. | Less margin for 200 V-class systems; may require higher-voltage downstream components. | Select when tighter VBR tolerance (±5%) is prioritized over lowest clamping voltage. |
| 1.5SMC200CA | Higher power (1500 W), same VBR range (180–220 V), but larger DO-214AB (SMC) package - incompatible footprint. | Not drop-in; requires PCB redesign; suited for higher-energy surge environments (e.g., telecom AC inputs). | Choose only if system-level testing confirms need for >600 W pulse handling and layout allows SMC footprint. |
Compared with SMBJ200CA and 1.5SMC200CA, the P6SMB200CH offers the lowest clamping voltage (287 V) in the SMB outline, enabling tighter protection margins for 200 V-rated circuits without increasing board area or cost.

FAQ
What is the polarity configuration of the P6SMB200CH?
The P6SMB200CH is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive and negative transients without polarity marking. Unlike unidirectional variants (e.g., P6SMB200H), it has no cathode band and functions identically across both terminals - ideal for differential bus protection like CAN or LIN where polarity reversal must be handled.
Does the P6SMB200CH meet ISO 7637-2 requirements?
Yes, the P6SMB200CH is explicitly rated to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b waveforms per Taiwan Semiconductor's official datasheet (Version A2102). This certification confirms its suitability for automotive applications involving load dump, supply interruption, and inductive switching transients in 12 V and 24 V systems.
What is the maximum clamping voltage of the P6SMB200CH and at what current?
The P6SMB200CH has a maximum clamping voltage (VC) of 287 V at a peak pulse current (IPPM) of 2.1 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events.
Can the P6SMB200CH be used in place of the unidirectional P6SMB200H?
No - the P6SMB200CH is bidirectional and lacks a cathode marking, while the P6SMB200H is unidirectional with defined anode/cathode polarity. Substituting them requires verifying circuit topology: P6SMB200CH is appropriate for symmetric protection (e.g., across differential lines), whereas P6SMB200H suits single-rail-to-ground configurations where polarity matters.
What is the thermal resistance and how does it affect PCB layout for the P6SMB200CH?
The P6SMB200CH has a junction-to-case thermal resistance (RθJC) of 10 °C/W. For reliable 3 W steady-state operation, this requires at least 25 mm² of 2-oz copper connected to both terminals. Layouts using minimal pad area or no thermal vias will exceed the +150 °C maximum junction temperature under continuous power stress.
