Product details
Overview
P6SMB8.2CAHE3/5B 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 or power lines. It features a 8.2 V breakdown voltage (VBR min/max = 7.79–8.61 V at 10 mA), 7.02 V stand-off voltage (VWM), and clamps to ≤12.1 V at 49.6 A peak pulse current (10/1000 µs), delivering 600 W peak pulse power for protection of MOSFETs, ICs, and sensor interfaces in automotive and industrial systems.
For engineers reviewing the P6SMB8.2CAHE3/5B datasheet, P6SMB8.2CAHE3/5B pinout, P6SMB8.2CAHE3/5B application, or P6SMB8.2CAHE3/5B equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 12.1 V maximum clamping voltage at rated IPPM, RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This device operates as a voltage-clamping protector using an avalanche junction structure, responding in sub-nanosecond time to transient overvoltages induced by inductive switching or ESD events. Its bidirectional symmetry enables use on AC-coupled or floating signal lines without polarity concerns.
Designed for repetitive surge handling under 0.01% duty cycle (10/1000 µs waveform), it maintains stable clamping performance across -65 °C to +150 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 7.79–8.61 V at 10 mA - defines precise voltage threshold where avalanche conduction begins in both directions |
| Stand-off Voltage VWM | 7.02 V - maximum continuous reverse voltage before leakage exceeds 200 µA, ensuring no false triggering during normal operation |
| Clamping Voltage VC | ≤12.1 V at 49.6 A (10/1000 µs) - limits transient voltage seen by downstream circuitry to safe levels |
| Peak Pulse Power PPPM | 600 W - sustains high-energy surges without failure when mounted on 5.0 mm × 5.0 mm copper pads |
| Operating Temperature | -65 °C to +150 °C - supports under-hood automotive and industrial environments requiring extended thermal robustness |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements including HTOL, TCT, and ESD HBM/MM |
| Package | SMB (DO-214AA) - low-profile surface-mount outline with 2.20 mm max height, optimized for automated pick-and-place |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads, UL 94 V-0 rated compound, dimensions 3.94 mm × 2.20 mm × 1.52 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; common node in bidirectional configuration | No polarity marking required - symmetrical construction allows either terminal to serve as input or return path during transient events |
| Cathode | Current exit terminal in forward bias; common node in bidirectional configuration | Identical electrical behavior to Anode - bidirectional operation eliminates need for orientation-dependent layout |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables robust protection against IEC 61000-4-5 Level 4 surges (4 kV line-to-line) without derating on standard PCB copper |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive-grade reliability including 1000-cycle temperature cycling and 1000-hour high-temperature operating life |
| Low incremental surge resistance | Minimizes VC – VBR differential (≤4.31 V), reducing stress on protected ICs during fast-rising transients |
| MSL Level 1, 260 °C peak reflow | Supports single-pass lead-free reflow assembly without moisture-related popcorn cracking or delamination |
| Glass passivated junction | Ensures stable leakage current (<200 µA at VWM) and long-term parameter stability under humidity and thermal stress |
Applications
| Automotive Sensor Interface Protection | Industrial CAN Bus Line Protection |
|---|---|
Use Scenario: Protecting analog output lines of engine coolant temperature or pressure sensors exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional clamping element placed between sensor output and microcontroller ADC input. Use Value: Limits transient excursions to ≤12.1 V, preventing ADC saturation and latch-up while maintaining signal integrity below 7.02 V nominal operation. |
Use Scenario: Safeguarding CANH/CANL differential pair against ESD and inductive kickback in factory automation nodes. IC Role / Device Role / Timing Role: Symmetrical TVS pair (one per line) referenced to ground, absorbing common-mode transients. Use Value: Clamps ±12.1 V surges without affecting CAN's 2.5 V common-mode window or 1–2 Mbps data rate due to low capacitance (<100 pF typical). |
| Consumer USB Port ESD Protection | Telecom DSL Line Surge Suppression |
Use Scenario: Shielding USB 2.0 D+/D− lines in set-top boxes from human-body-model (HBM) ESD events up to ±15 kV. IC Role / Device Role / Timing Role: Low-capacitance bidirectional suppressor placed inline with data traces prior to USB transceiver. Use Value: Provides <200 µA leakage at 5 V and sub-1 ns response, preserving signal rise/fall times and avoiding bit errors. |
Use Scenario: Front-end protection of ADSL/VDSL line drivers against lightning-induced surges on twisted-pair telephone lines. IC Role / Device Role / Timing Role: Primary clamping device bridging tip/ring to ground, coordinated with gas discharge tube (GDT) secondary protection. Use Value: Handles 600 W surges per ITU-T K.20/K.21 standards while maintaining ≤12.1 V let-through voltage to preserve line driver SOA. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0CA | Lower VBR (7.6–8.4 V), same SMB package, 400 W PPPM, non-AEC-Q101 | Limited to commercial-grade industrial or consumer use; insufficient for automotive under-hood deployment | Select when cost sensitivity outweighs AEC-Q101 requirement and 400 W surge margin suffices |
| 1.5SMC8.2CA | Same VBR/VWM, higher PPPM (1500 W), larger SMC (DO-214AB) package, AEC-Q101 available (HE3 variant) | Requires larger PCB footprint (7.11 mm × 6.22 mm); better suited for high-energy telecom or power supply inputs | Choose when system-level surge tests exceed 600 W or board space permits larger package for enhanced margin |
Compared with SMAJ8.0CA and 1.5SMC8.2CA, P6SMB8.2CAHE3/5B uniquely balances AEC-Q101 compliance, SMB footprint constraints, and 600 W surge capability-making it optimal for space-constrained automotive modules where qualification and form factor are non-negotiable.

FAQ
What does the "CA" suffix indicate in P6SMB8.2CAHE3/5B?
The "CA" suffix denotes that P6SMB8.2CAHE3/5B is a bidirectional Transient Voltage Suppressor, meaning it provides symmetrical clamping in both polarities-ideal for protecting AC-coupled or floating signal lines such as CAN bus, USB differential pairs, or audio interfaces without requiring polarity-aware layout.
Is P6SMB8.2CAHE3/5B suitable for automotive applications?
Yes, P6SMB8.2CAHE3/5B is AEC-Q101 qualified (indicated by the "HE3" suffix), having passed stress tests including high-temperature operating life, temperature cycling, and ESD robustness-making it appropriate for under-hood and body-control module deployments where reliability under thermal and electrical stress is critical.
What is the maximum clamping voltage of P6SMB8.2CAHE3/5B at its rated peak pulse current?
The maximum clamping voltage (VC) of P6SMB8.2CAHE3/5B is 12.1 V when subjected to its rated peak pulse current of 49.6 A under the standardized 10/1000 µs waveform condition-ensuring downstream ICs experience no more than this voltage during surge events.
How does the SMB (DO-214AA) package of P6SMB8.2CAHE3/5B compare to larger alternatives like SMC?
The SMB package of P6SMB8.2CAHE3/5B measures 3.94 mm × 2.20 mm × 1.52 mm-significantly smaller than the SMC (DO-214AB) package-enabling dense routing in compact modules while still delivering 600 W peak pulse power, unlike smaller SOD-123 or SC-79 packages limited to ≤400 W.
Does P6SMB8.2CAHE3/5B require special PCB layout considerations?
Yes-P6SMB8.2CAHE3/5B achieves its rated 600 W pulse power only when mounted on minimum recommended 5.0 mm × 5.0 mm copper pads per terminal; undersized traces or thermal reliefs will reduce surge capability and risk thermal runaway during repetitive transients.
