Product details
Overview
P6SMB82CA-E3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal and power lines. It features a 70.1 V standoff 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, and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB82CA-E3/5B datasheet, P6SMB82CA-E3/5B pinout, P6SMB82CA-E3/5B application, or P6SMB82CA-E3/5B equivalent, key selection criteria include bidirectional clamping symmetry, low clamping ratio (VC/VBR ≈ 1.43), MSL Level 1 moisture sensitivity, RoHS-compliant matte tin plating, and SMB (DO-214AA) package compatibility with automated SMT placement.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, delivering identical clamping performance regardless of transient polarity - critical for AC-coupled or floating signal lines. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns), while low incremental surge resistance enables effective energy diversion during ESD or lightning-induced surges.
The device is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient per Figure 2; thermal resistance is 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads. It meets JESD201 Class 2 whisker resistance and is qualified to AEC-Q101 when ordered with HE3/HM3 suffixes - though P6SMB82CA-E3/5B itself is commercial-grade.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 70.1 V - maximum continuous reverse voltage before conduction begins; defines safe operating window for protected circuitry. |
| VBR (Breakdown) | 77.9–86.1 V at 1 mA - sharp avalanche onset ensures predictable clamping threshold across production lot. |
| VC (Clamping) | 113 V at 5.3 A IPPM - limits transient voltage seen by downstream components during 10/1000 μs surge events. |
| PPPM | 600 W - peak pulse power handling with 0.01% duty cycle; supports repetitive surge immunity in industrial environments. |
| Package | SMB (DO-214AA) - standardized surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height; compatible with JEDEC MS-012. |
| Leakage (ID) | <1.0 μA at VWM - negligible standby current draw, preserving low-power sensor node battery life. |
| Temperature Range | –65 °C to +150 °C - wide operational envelope suitable for under-hood automotive and outdoor industrial deployments. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking - terminals are symmetrical and interchangeable. Cathode/anode designation does not apply; both ends function identically.

Applications
| Automotive Sensor Interface Protection | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) from load dump and inductive switching transients in 12 V/24 V vehicle systems. IC Role / Device Role: Bidirectional clamping element placed directly at connector entry point to shunt surge energy before it reaches precision amplifier or microcontroller input pins. Use Value: Maintains signal integrity by limiting transient overshoot to ≤113 V while drawing <1 μA leakage - avoids false triggering or ADC saturation in sub-16-bit measurement systems. | Use Scenario: Safeguarding 4–20 mA current loop inputs and ±10 V analog inputs in programmable logic controllers exposed to motor drive noise and relay coil kickback. IC Role / Device Role: Primary overvoltage clamp on field-side I/O terminals, coordinated with series impedance and filtering to meet IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) requirements. Use Value: Enables compliance with industrial immunity standards using a single discrete component - eliminates need for multi-stage protection or custom TVS arrays. |
| Telecom Line Card Surge Protection | Consumer Appliance Motor Drive Protection |
Use Scenario: Shielding Ethernet PHYs, DSL line drivers, and POTS interface ICs from lightning-induced surges entering via RJ-45 or telephone jacks in network edge equipment. IC Role / Device Role: First-line transient suppressor on unshielded twisted-pair (UTP) lines, operating in conjunction with common-mode chokes and gas discharge tubes for staged protection. Use Value: Fast sub-nanosecond response captures initial surge edge; 113 V clamping prevents latch-up in 3.3 V/5 V PHYs while surviving repeated 6 kV/3 kA tests per ITU-T K.20/K.21. | Use Scenario: Suppressing commutation spikes from brushed DC motors and triac-controlled AC loads in washing machines, HVAC controls, and power tools. IC Role / Device Role: Snubber-style clamp across motor terminals or relay contacts to limit dv/dt and prevent EMI coupling into adjacent control logic. Use Value: Reduces radiated emissions by >10 dB in 30–200 MHz band; extends relay contact life by lowering arcing energy during turn-off. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ82CA | Same SMB package, identical VWM/VBR/VC, but rated for 600 W with tighter VBR tolerance (±5% vs. ±6.5% for P6SMB82CA); slightly lower RθJA (90 °C/W). | Preferred where tighter parametric consistency or marginally better thermal performance is required in space-constrained designs. | Select SMBJ82CA if design requires tighter breakdown tolerance or higher-volume qualification traceability; P6SMB82CA-E3/5B offers broader voltage range availability and lower cost in high-mix production. |
| 1.5SMC82CA | Larger SMC (DO-214AB) package (7.11 mm × 6.22 mm); same electrical specs but higher thermal mass - RθJA = 65 °C/W on same pad layout. | Better suited for high-repetition-rate surge environments (e.g., factory automation) where sustained power dissipation matters more than board area. | Choose 1.5SMC82CA only when PCB real estate permits larger footprint and thermal performance outweighs size constraints - not a drop-in replacement due to different land pattern. |
Compared with SMBJ82CA, P6SMB82CA-E3/5B trades minor VBR tolerance for broader family scalability and cost efficiency; versus 1.5SMC82CA, it delivers identical protection in 35% less board area but requires careful thermal management under sustained surge conditions.

FAQ
What is the clamping voltage of P6SMB82CA-E3/5B at its rated peak pulse current?
The P6SMB82CA-E3/5B has a maximum clamping voltage (VC) of 113 V at 5.3 A peak pulse current (IPPM) under a 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and represents the upper bound of voltage imposed on protected circuitry during worst-case surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is P6SMB82CA-E3/5B suitable for automotive applications requiring AEC-Q101 qualification?
No, P6SMB82CA-E3/5B is a commercial-grade part with RoHS-compliant matte tin plating but lacks AEC-Q101 qualification. For automotive use, specify P6SMB82CAHE3_B or P6SMB82CAHM3_B - these variants carry the HE3 or HM3 suffix and are explicitly qualified to AEC-Q101 per Note (1) on page 3 of datasheet 88370.
What is the standoff voltage (VWM) of P6SMB82CA-E3/5B, and how does it relate to system operating voltage?
The standoff voltage (VWM) of P6SMB82CA-E3/5B is 70.1 V - the maximum DC or continuous peak AC voltage the device blocks without significant leakage. It must exceed the normal operating voltage of the protected line (e.g., 48 V DC bus or 50 V AC RMS) by at least 10–15% to avoid false triggering while maintaining sufficient margin below VBR.
Does P6SMB82CA-E3/5B have polarity markings, and how is it mounted on PCB?
No, P6SMB82CA-E3/5B is a bidirectional TVS and carries no polarity marking on its SMB (DO-214AA) package. Both terminals are functionally identical; orientation during placement is irrelevant. Mounting uses standard reflow profiles for matte tin terminations, with recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for optimal thermal and surge performance.
What is the peak pulse power rating of P6SMB82CA-E3/5B, and under what test conditions is it specified?
The peak pulse power rating (PPPM) of P6SMB82CA-E3/5B is 600 W, defined per a 10/1000 μs double-exponential waveform with 0.01% duty cycle and TA = 25 °C. This rating assumes mounting on 0.2" × 0.2" copper pads per terminal (per Figure 2 in datasheet 88370) and applies to both unidirectional and bidirectional operation modes.
