Product details
Overview
P6SMB8.2CAHE3_A/H 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 or power lines. It features a 8.2 V standoff voltage (VWM), 12.1 V maximum clamping voltage at 49.6 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial electronics.
For engineers reviewing the P6SMB8.2CAHE3_A/H datasheet, P6SMB8.2CAHE3_A/H pinout, P6SMB8.2CAHE3_A/H application, or P6SMB8.2CAHE3_A/H equivalent, key selection criteria include bidirectional clamping performance, AEC-Q101 qualification status, SMB (DO-214AA) package compatibility, and compliance with IEC 61000-4-2/4-4/4-5 surge immunity requirements.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical breakdown behavior in both polarities due to its bidirectional construction. Its glass-passivated junction ensures stable leakage and fast response (<1 ns), while the low incremental surge resistance enables effective energy diversion during ESD or lightning-induced surges.
The P6SMB8.2CAHE3_A/H is rated for 150 °C maximum junction temperature and meets MSL level 1 per J-STD-020 with 260 °C reflow peak. It delivers 600 W peak pulse power under standardized 10/1000 μs waveform conditions at 0.01% duty cycle, with thermal resistance of 100 °C/W (junction-to-ambient) on recommended 5.0 mm × 5.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 7.02 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 7.79 V (min) to 8.61 V (max) at 10 mA - Ensures reliable triggering across manufacturing tolerance and temperature range. |
| VC (Clamping Voltage) | 12.1 V at 49.6 A IPPM - Limits transient voltage seen by protected circuitry to safe levels during surge events. |
| PPPM (Peak Pulse Power) | 600 W - Sustains high-energy transients without failure when applied with 10/1000 μs waveform. |
| ID (Reverse Leakage) | 200 μA max at VWM - Low leakage preserves signal integrity and minimizes standby power loss in sensitive circuits. |
| TJ max | 150 °C - Enables operation in under-hood automotive and industrial environments with elevated ambient temperatures. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0CA | Lower VWM (6.4 V), lower VC (12.0 V), same SMB package and 600 W rating. | Slightly tighter clamping margin; better suited for 5 V logic rails where 7.02 V VWM provides less headroom. | Select SMAJ8.0CA if system requires lower stand-off voltage while retaining identical footprint and surge rating. |
| 1.5KE8.2CA | Higher power (1500 W), axial DO-15 package, higher thermal resistance (70 °C/W junction-to-lead). | Not surface-mount compatible; requires through-hole layout and larger board area; better for high-reliability industrial mains inputs. | Choose 1.5KE8.2CA only when higher pulse energy handling is required and PCB layout allows axial component placement. |
Compared with SMAJ8.0CA and 1.5KE8.2CA, the P6SMB8.2CAHE3_A/H offers AEC-Q101 qualification and MSL Level 1 reflow compatibility out-of-the-box - critical for automotive SMT production - while delivering optimized clamping performance in the widely adopted SMB footprint.

FAQ
What does the "CA" suffix indicate in P6SMB8.2CAHE3_A/H?
The "CA" suffix denotes a bidirectional configuration, meaning the P6SMB8.2CAHE3_A/H provides symmetrical clamping for both positive and negative transients without polarity sensitivity. This differs from unidirectional variants (e.g., P6SMB8.2A) that require correct cathode orientation and only clamp in one direction. The CA version is ideal for AC-coupled or floating signal lines.
Is P6SMB8.2CAHE3_A/H qualified for automotive use?
Yes, P6SMB8.2CAHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code structure ("HE3" indicates RoHS-compliant and AEC-Q101 qualified). It has undergone stress testing including temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 Rev D, making it suitable for under-hood and body electronics applications.
What is the maximum clamping voltage of P6SMB8.2CAHE3_A/H and at what current is it specified?
The maximum clamping voltage (VC) of P6SMB8.2CAHE3_A/H is 12.1 V, measured at a peak pulse current (IPPM) of 49.6 A using the standardized 10/1000 μs double-exponential waveform. This value represents the upper limit of voltage imposed on protected circuitry during worst-case surge events.
How does the SMB (DO-214AA) package of P6SMB8.2CAHE3_A/H compare to SMA or SMC packages?
The SMB (DO-214AA) package of P6SMB8.2CAHE3_A/H measures 3.94 mm × 2.20 mm × 1.52 mm - smaller than SMC (DO-214AB) but larger than SMA (DO-214AC). It offers a balance of surge capability (600 W), thermal performance (RθJA = 100 °C/W), and compatibility with standard pick-and-place equipment, unlike the larger SMC or smaller SMA which trade off power rating or manufacturability.
Does P6SMB8.2CAHE3_A/H meet JEDEC moisture sensitivity level requirements?
Yes, P6SMB8.2CAHE3_A/H meets MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. This eliminates bake requirements prior to assembly and supports standard lead-free reflow profiles, simplifying manufacturing for high-volume automotive and industrial PCB assembly.
