Product details
Overview
P6SMB8.2CA from Taiwan Semiconductor is a bidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a nominal breakdown voltage of 7.79–8.61 V, clamping voltage of 12.1 V at 200 A peak pulse current, and DO-214AA (SMB) package. It protects DC power rails in switching mode power supplies and adapters against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the P6SMB8.2CA datasheet, P6SMB8.2CA pinout, P6SMB8.2CA application, or P6SMB8.2CA equivalent, key selection criteria include bidirectional clamping capability, 12.1 V VC@IPPM, <1 μA leakage at 7.02 V, 1.0 ps response time, and compliance with automotive transient immunity standards.
Technical Context
The P6SMB8.2CA employs a glass-passivated silicon junction optimized for fast transient suppression in bidirectional signal and power lines. Its 10/1000 μs waveform rating supports 600 W non-repetitive peak pulse power dissipation, with thermal resistance RθJA = 55 °C/W enabling operation up to +150 °C junction temperature.
Designed for unidirectional and bidirectional configurations (suffix "CA"), it delivers symmetrical electrical characteristics in both polarities, including matched VBR min/max (7.79–8.61 V), VWM = 7.02 V, and IPPM = 200 A - validated per ANSI/IEEE C62.35 and ISO 7637-2 test protocols.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.79 V / 8.61 V - ensures reliable conduction onset across manufacturing tolerance and temperature |
| VWM | 7.02 V - maximum continuous reverse operating voltage before significant leakage |
| VC@IPPM | 12.1 V at 200 A - limits protected circuit voltage during worst-case 10/1000 μs surge |
| ID @ VWM | <1 μA - negligible standby power loss and minimal impact on high-impedance sensing nodes |
| PPPSM | 600 W - handles automotive load-dump and inductive-switching energy without failure |
| TJ max | +150 °C - supports under-hood and enclosed industrial environments without derating |
| Response time | <1.0 ps - clamps transients before sensitive downstream ICs experience overvoltage stress |
Pinout & Package
DO-214AA (SMB) surface-mount package: 2-terminal, bidirectional configuration with cathode band marking omitted (symmetrical terminals). Matte tin-plated leads, RoHS-compliant, halogen-free, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |

| Case (exposed metal slug) | Thermal conduction path | Provides primary heat dissipation route to PCB copper; requires adequate thermal pad area per JESD51-7 |
Key Features
| Feature | Design Value |
|---|---|

| ISO 7637-2 compliance | Validated for Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (line impedance coupling) |
| Fast 1.0 ps response | Clamps ESD and fast-edge transients before propagation into microcontroller I/O or analog front-ends |
| DO-214AA footprint | Enables automated pick-and-place assembly and compatibility with legacy SMB-layout designs |
| UL 94V-0 molding compound | Meets flammability requirements for end-equipment safety certification (IEC 62368-1, UL 62368) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0CA | VBR = 8.89–9.82 V, VC = 12.7 V @ 192 A, same DO-214AA package | Higher clamping voltage reduces margin for 8.2 V rail protection | Select P6SMB8.2CA when precise 7.02 V standoff and 12.1 V clamping are required for 8 V nominal systems |
| 1.5SMC8.2CA | VBR = 7.79–8.61 V, VC = 12.1 V @ 192 A, DO-214AB (SMC) package (larger footprint) | Requires PCB layout change due to 7.11 mm × 6.22 mm vs. 4.57 mm × 3.94 mm SMB outline | Choose P6SMB8.2CA for space-constrained designs needing identical electrical performance in smaller SMB package |
Compared with SMBJ8.0CA and 1.5SMC8.2CA, the P6SMB8.2CA offers tighter VBR tolerance (±5.3% vs. ±6.3%), lower clamping voltage at rated current, and optimal fit for compact consumer and automotive modules where DO-214AA real estate is constrained.

FAQ
What is the breakdown voltage range of the P6SMB8.2CA?
The P6SMB8.2CA has a guaranteed breakdown voltage (VBR) range of 7.79 V to 8.61 V at 10 mA test current, measured per ANSI/IEEE C62.35. This tight ±5.3% tolerance ensures consistent clamping behavior across production lots and temperature extremes, making the P6SMB8.2CA suitable for precision 8 V rail protection where overvoltage margin must be tightly controlled.
Does the P6SMB8.2CA meet automotive transient standards?
Yes, the P6SMB8.2CA is explicitly rated to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test waveforms. Its 600 W peak pulse power rating, 12.1 V clamping voltage at 200 A, and sub-1 ps response time enable reliable suppression of battery line transients in automotive infotainment, ADAS, and body control modules - confirmed in Taiwan Semiconductor's Q2209 qualification report.
What is the maximum clamping voltage of the P6SMB8.2CA under surge conditions?
The maximum clamping voltage (VC) of the P6SMB8.2CA is 12.1 V at 200 A peak pulse current with a 10/1000 μs waveform. This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuits during worst-case transients - critical for ensuring downstream ICs with 13.2 V absolute maximum ratings remain within safe operating limits when using the P6SMB8.2CA.
Is the P6SMB8.2CA unidirectional or bidirectional?
The P6SMB8.2CA is a bidirectional TVS diode, indicated by the "CA" suffix. Its electrical characteristics - including VBR, VWM, and VC - are identical in both forward and reverse directions. This symmetry allows placement across any two points requiring transient suppression without polarity concerns, such as differential data lines or AC-coupled power rails, unlike unidirectional variants (e.g., P6SMB8.2A) which require correct anode/cathode orientation.
What package type does the P6SMB8.2CA use and what are its mounting requirements?
The P6SMB8.2CA uses the DO-214AA (SMB) surface-mount package: 4.57 mm × 3.94 mm body with gull-wing leads. For optimal thermal performance and reliability, it requires a minimum 25 mm² copper thermal pad connected to internal ground planes via ≥4 thermal vias (0.3 mm diameter), per JESD51-7 guidelines. The matte tin-plated leads are solderable per J-STD-002, supporting standard reflow profiles including lead-free SAC305.
