Product details
Overview
P6SMB8.2CA-M3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features 8.2 V standoff voltage (VWM), 12.1 V maximum clamping voltage (VC) at 49.6 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the P6SMB8.2CA-M3/52 datasheet, P6SMB8.2CA-M3/52 pinout, P6SMB8.2CA-M3/52 application, or P6SMB8.2CA-M3/52 equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VWM = 1.48), halogen-free RoHS compliance (M3 suffix), AEC-Q101 qualification readiness, and compatibility with automated SMT assembly on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a bidirectional avalanche diode, symmetrically clamping both positive and negative transients without polarity dependence. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<200 μA at VWM), while the low incremental surge resistance enables rapid energy diversion during ESD or lightning-induced surges.
The P6SMB8.2CA-M3/52 delivers consistent clamping performance across -65 °C to +150 °C junction temperature range, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead). It meets J-STD-020 MSL Level 1 and supports reflow up to 260 °C peak, making it suitable for high-reliability commercial and automotive-grade PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 7.02 V - Maximum continuous reverse voltage before conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 7.79–8.61 V at 10 mA - Verified avalanche onset range; ensures predictable turn-on under transient stress. |
| VC (Clamping Voltage) | 12.1 V at 49.6 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs surge; critical for IC-level survivability. |
| PPPM (Peak Pulse Power) | 600 W - Sustained transient energy absorption capacity per single event; validated per Fig. 1 derating curve. |
| ID (Reverse Leakage) | <200 μA at VWM - Minimal standby power loss and signal integrity impact in high-impedance circuits. |
| TJ max. | +150 °C - Enables operation in under-hood automotive and industrial environments without thermal shutdown. |
| Package | SMB (DO-214AA) - Standardized 2-pin SMT outline with 5.59 mm × 4.06 mm footprint; compatible with JEDEC-standard pick-and-place. |

Applications
| Automotive Sensor Interface | Industrial Digital I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed between signal line and ground, responding within <1 ns to suppress transients above 7.02 V. Use Value: Prevents latch-up or gate oxide damage in downstream ASICs by limiting voltage excursion to ≤12.1 V during 49.6 A surge events. |
Use Scenario: Shielding PLC digital input modules from inductive kickback caused by relay/solenoid switching in factory automation systems. IC Role / Device Role / Timing Role: Fast-acting shunt protector across input terminals, diverting surge current away from optocoupler input stages. Use Value: Maintains functional safety integrity by ensuring input logic states remain valid during 600 W transient events without component degradation. |
| Consumer USB Port ESD Protection | Telecom Line Card Surge Suppression |
Use Scenario: Safeguarding USB 2.0 data lines (D+/D−) against human-body-model (HBM) ESD events in portable devices. IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS placed directly at connector, clamping ±8 kV contact discharge per IEC 61000-4-2. Use Value: Preserves signal integrity with minimal added capacitance while meeting Class 4 ESD immunity without sacrificing data rate. |
Use Scenario: Front-end protection of xDSL or Ethernet PHY interfaces exposed to lightning-induced surges on outside plant wiring. IC Role / Device Role / Timing Role: Primary coarse-clamp device upstream of precision protection ICs, absorbing bulk surge energy before secondary suppression. Use Value: Extends system MTBF by reducing stress on downstream TVS arrays and transient filters during repetitive 10/1000 μs line surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0CA | 8.0 V VWM, 12.0 V VC at 50.0 A; same SMB package but slightly tighter VBR tolerance (7.6–8.4 V). | Marginally lower clamping voltage; preferred where sub-12 V rail protection is critical. | Select SMBJ8.0CA if design requires tighter VWM tolerance and verified 12.0 V clamping ceiling. |
| 1.5SMC8.2CA | Same VWM/VC specs but in larger SMC (DO-214AB) package; 1.5 kW PPPM rating and higher thermal mass. | Used where board space allows larger footprint and higher surge repetition rates are expected. | Choose 1.5SMC8.2CA for industrial power supplies needing >600 W duty-cycle headroom or improved thermal dissipation. |
Compared with SMBJ8.0CA and 1.5SMC8.2CA, the P6SMB8.2CA-M3/52 offers optimal balance of compact SMB footprint, halogen-free compliance, and precise 7.02 V standoff - making it ideal for space-constrained automotive and consumer designs where MSL Level 1 reflow and AEC-Q101 upgrade path matter.

FAQ
What is the clamping voltage of P6SMB8.2CA-M3/52 at its rated peak pulse current?
The P6SMB8.2CA-M3/52 has a maximum clamping voltage (VC) of 12.1 V at 49.6 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per Figure 1 in Vishay document 88370 and defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB8.2CA-M3/52 maintains this clamping performance across its full operating temperature range.
Is P6SMB8.2CA-M3/52 suitable for automotive applications?
Yes - the P6SMB8.2CA-M3/52 is halogen-free and RoHS-compliant (M3 suffix), and its base family supports AEC-Q101 qualification via HM3_X variants. While the exact P6SMB8.2CA-M3/52 part number is commercial-grade, it shares identical electrical and mechanical characteristics with qualified versions and is widely used in automotive sensor modules and body control units where qualification is pending or not mandated. The P6SMB8.2CA-M3/52 operates reliably from -65 °C to +150 °C.
How does the bidirectional nature of P6SMB8.2CA-M3/52 affect PCB layout?
The P6SMB8.2CA-M3/52 has no polarity marking and functions identically in both directions, eliminating orientation constraints during placement. This simplifies PCB layout for AC-coupled signals, differential buses (e.g., RS-485), or uncommitted I/O lines - no need to verify anode/cathode alignment. The device must still be mounted on minimum 5.0 mm × 5.0 mm copper pads per terminal to achieve rated 600 W pulse power, as specified in Vishay's thermal guidelines for the P6SMB8.2CA-M3/52.
What is the reverse leakage current specification for P6SMB8.2CA-M3/52 at its stand-off voltage?
The P6SMB8.2CA-M3/52 exhibits maximum reverse leakage current (ID) of 200 μA at its 7.02 V stand-off voltage (VWM), tested at TA = 25 °C. This low leakage preserves signal integrity in high-impedance sensor front-ends and minimizes standby power loss in battery-operated systems. The P6SMB8.2CA-M3/52 maintains leakage below 500 μA up to +125 °C, per derating curves in the official datasheet.
Does P6SMB8.2CA-M3/52 require special handling or moisture sensitivity precautions?
No - the P6SMB8.2CA-M3/52 is rated MSL Level 1 per J-STD-020, meaning it may be stored indefinitely at ambient conditions and subjected to standard lead-free reflow profiles with peak temperature up to 260 °C without baking or dry-pack requirements. This eliminates moisture sensitivity handling steps in manufacturing, reducing cost and process risk for the P6SMB8.2CA-M3/52 in high-volume SMT lines.
