Product details
Overview
P6SMB82CA-M3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 70.1 V stand-off voltage (VWM), 77.9–86.1 V breakdown voltage (VBR) at 1 mA, 113 V maximum clamping voltage (VC) at 5.3 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 μs waveform.
For engineers reviewing the P6SMB82CA-M3/5B datasheet, P6SMB82CA-M3/5B pinout, P6SMB82CA-M3/5B application, or P6SMB82CA-M3/5B equivalent, this device serves as a robust, halogen-free, RoHS-compliant protection solution for automotive-grade and industrial electronics where bidirectional surge immunity and low incremental surge resistance are required.
Technical Context
The P6SMB82CA-M3/5B operates symmetrically in both directions due to its bidirectional construction, enabling suppression of positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the M3 suffix confirms halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance.
Thermally, it supports operation from −65 °C to +150 °C junction temperature, with a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W on standard 0.2" × 0.2" copper pads. It meets MSL Level 1 per J-STD-020 and is rated for repetitive 0.01% duty cycle pulses under defined derating conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 70.1 V - Maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping threshold |
| VBR (Breakdown) | 77.9–86.1 V at 1 mA - Confirmed voltage range where device enters avalanche conduction; tight tolerance enables predictable turn-on |
| VC (Clamping) | 113 V at IPPM = 5.3 A - Peak voltage seen by protected circuit during 10/1000 μs transient; critical for IC-level stress budgeting |
| PPPM | 600 W - Peak pulse power handling with 10/1000 μs waveform; determines survivability against common lightning/inductive-spike threats |
| ID (Leakage) | 1.0 μA max at VWM - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss in high-impedance nodes |
| TJ max | +150 °C - Maximum junction temperature rating; supports operation in under-hood automotive and industrial environments |
| Package | SMB (DO-214AA) - Low-profile SMD outline with 5.59 mm length and 3.94 mm width; optimized for automated placement and board space efficiency |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Terminals are matte tin-plated, solderable per J-STD-002 and JESD22-B102.

Applications
| Automotive Sensor Interface Protection | Industrial CAN Bus Line Protection |
|---|---|
Use Scenario: Protecting analog sensor outputs (e.g., pressure, temperature) in engine control units from load-dump and ISO 7637-2 transients. IC Role / Device Role / Timing Role: Bidirectional TVS placed across differential sensor pair or between signal and ground to clamp ±100 V spikes.

| Telecom Power Supply Input Protection | Consumer USB Port Surge Suppression |
Use Scenario: Secondary-side DC input protection for PoE-powered network switches exposed to induced surges from Ethernet cabling. IC Role / Device Role / Timing Role: Placed between DC input rail and ground to limit voltage excursions during lightning-induced surges on upstream cabling. Use Value: Clamps 113 V peak within microseconds, protecting downstream DC-DC controllers and ensuring system-level IEC 61000-4-5 compliance. |

IC Role / Device Role / Timing Role: Bidirectional TVS across D+ and D− pins to suppress both polarities of fast transients without disrupting 480 Mbps signaling. Use Value: Limits clamping voltage to 113 V while adding <0.5 pF capacitance (per diode), preserving signal rise/fall times and eye diagram integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ85CA | Higher VWM (72.2 V), higher VC (121 V at 5.0 A), same SMB package and 600 W rating | Marginally looser clamping ratio; suitable where slightly higher let-through voltage is acceptable | Select SMAJ85CA if design requires tighter VBR tolerance (±5%) versus P6SMB82CA-M3/5B's ±5.5% and higher surge margin at elevated temperatures |
| SMCJ85CA | Same VWM/VC specs but in larger SMC (DO-214AB) package; 1500 W peak power rating | Requires more PCB area; used where higher single-pulse energy absorption is needed beyond 600 W | Choose SMCJ85CA only when system-level testing reveals insufficient margin with 600 W rating-otherwise P6SMB82CA-M3/5B offers superior space efficiency |
Compared with SMAJ85CA and SMCJ85CA, the P6SMB82CA-M3/5B delivers optimal balance of compact SMB footprint, verified 600 W surge capability, and automotive-grade halogen-free construction-making it preferred for space-constrained, high-volume industrial and automotive modules where layout density and regulatory compliance are prioritized.

FAQ
What is the clamping voltage of the P6SMB82CA-M3/5B under a 10/1000 μs surge?
The P6SMB82CA-M3/5B has a maximum clamping voltage (VC) of 113 V at a peak pulse current (IPPM) of 5.3 A with a 10/1000 μs waveform. This value is measured under standardized test conditions per JEDEC standards and represents the highest voltage the protected circuit will experience during such a transient event. The P6SMB82CA-M3/5B maintains this performance across its specified operating temperature range when mounted per recommended pad layout.
Is the P6SMB82CA-M3/5B suitable for automotive applications?
Yes-the P6SMB82CA-M3/5B is halogen-free and RoHS-compliant (M3 suffix), and the P6SMB series offers AEC-Q101 qualified variants (e.g., P6SMB82CAHM3_B). While the specific P6SMB82CA-M3/5B part number is commercial-grade, its construction-including glass-passivated junction, MSL Level 1 rating, and −65 °C to +150 °C operating range-supports deployment in non-safety-critical automotive subsystems like body electronics and infotainment when validated per customer requirements. Always verify qualification status for safety-relevant use cases.
How does the bidirectional configuration of the P6SMB82CA-M3/5B affect PCB layout?
The P6SMB82CA-M3/5B has no polarity marking and functions identically in both directions, eliminating orientation constraints during placement. This simplifies PCB layout for differential or floating signal lines-no need to align cathode bands-and reduces assembly errors. Layout must still follow Vishay's recommended 0.2" × 0.2" copper pad dimensions per terminal to ensure thermal performance and peak pulse current handling. The P6SMB82CA-M3/5B's symmetry also allows reuse across multiple signal pairs without redesign.
What is the maximum reverse leakage current for the P6SMB82CA-M3/5B at its stand-off voltage?
The P6SMB82CA-M3/5B exhibits a maximum reverse leakage current (ID) of 1.0 μA at its rated stand-off voltage (VWM) of 70.1 V and TA = 25 °C. This ultra-low leakage ensures minimal loading on high-impedance circuits such as sensor bias networks or reference voltage dividers. Leakage remains well below 10 μA even at +85 °C ambient, supporting reliable operation in thermally demanding environments without degrading signal accuracy or increasing quiescent power.
Can the P6SMB82CA-M3/5B replace a unidirectional TVS in an existing design?
No-the P6SMB82CA-M3/5B is strictly bidirectional and cannot substitute for a unidirectional TVS where DC bias or polarity-dependent conduction is required (e.g., protecting a positive-only supply rail). Attempting replacement may result in unintended conduction during normal operation. If bidirectional protection is acceptable and the clamping parameters align, the P6SMB82CA-M3/5B can be used-but always validate with actual surge testing. For unidirectional applications, select the corresponding 'A' suffix variant (e.g., P6SMB82A-M3/5B).
