Product details
Overview
P6SMB10CAHE3/5B 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 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage at 41.4 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 industrial and automotive electronics.
For engineers reviewing the P6SMB10CAHE3/5B datasheet, P6SMB10CAHE3/5B pinout, P6SMB10CAHE3/5B application, or P6SMB10CAHE3/5B equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification, low clamping voltage relative to VWM, thermal resistance (RθJA = 100 °C/W), and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical breakdown in both directions due to its bidirectional construction. It exhibits a typical breakdown voltage (VBR) of 10.5–11.6 V at 1 mA test current and maintains stable clamping performance up to 150 °C junction temperature.
The P6SMB10CAHE3/5B uses a glass-passivated silicon junction and meets J-STD-020 MSL Level 1 moisture sensitivity with 260 °C lead-free reflow peak. Its unmarked SMB package indicates bidirectional polarity, and it delivers 0.073 %/°C temperature coefficient of VBR - critical for stable transient suppression across operating temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 10 V - Maximum continuous reverse voltage before clamping begins; defines safe operating window for protected circuitry. |
| VBR (Breakdown) | 10.5–11.6 V at 1 mA - Confirmed breakdown threshold where TVS enters avalanche conduction; ensures predictable turn-on during transients. |
| VC (Clamping) | 14.5 V at 41.4 A - Maximum voltage seen by downstream components during 10/1000 μs surge; enables robust protection of 12 V logic and analog interfaces. |
| PPPM | 600 W - Peak pulse power handling with 10/1000 μs waveform; supports repetitive surge events at 0.01 % duty cycle without degradation. |
| ID (Leakage) | 10 μA max at VWM - Low reverse leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max | 150 °C - Maximum junction temperature rating; allows operation in under-hood automotive and industrial environments. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient; requires minimum 0.2" × 0.2" copper pads per terminal for rated power dissipation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA | Same SMB package, 10 V VWM, but lower PPPM (400 W) and higher VC (17.0 V at 24.7 A); not AEC-Q101 qualified. | Limited to commercial-grade consumer or office equipment; unsuitable for automotive or harsh industrial use. | Select SMAJ10CA only if cost is primary constraint and AEC-Q101 or 600 W surge margin is unnecessary. |
| SMCJ10CA | Higher-power SMC (DO-214AB) package, same VWM and VBR, but 1500 W PPPM and lower RθJA (35 °C/W); AEC-Q101 available in HE3 variant. | Requires larger PCB footprint; better suited for high-energy surges like IEC 61000-4-5 Level 5 or motor drive feedback lines. | Choose SMCJ10CAHE3 when system-level surge testing exceeds 600 W or thermal management demands lower junction rise. |
Compared with SMAJ10CA, P6SMB10CAHE3/5B offers 50 % higher surge power handling and automotive qualification; versus SMCJ10CAHE3, it trades 2.5× surge capacity for 30 % smaller board area and identical AEC-Q101 compliance - making it optimal for space-constrained automotive modules.

The "CA" suffix denotes a bidirectional configuration: the P6SMB10CAHE3/5B provides symmetrical transient suppression in both polarities, with no cathode band marking. This enables line-to-line or line-to-ground clamping without polarity concerns - unlike unidirectional variants (e.g., P6SMB10A) that require correct orientation during placement.
Is P6SMB10CAHE3/5B suitable for automotive applications?
Yes, P6SMB10CAHE3/5B is AEC-Q101 qualified (indicated by the "HE3" suffix) and rated for −65 °C to +150 °C operation. It meets automotive surge immunity requirements including ISO 7637-2 and IEC 61000-4-5 when mounted per recommended pad layout - making it appropriate for engine control units, body electronics, and ADAS sensor modules.
What is the maximum clamping voltage of P6SMB10CAHE3/5B under surge conditions?
The P6SMB10CAHE3/5B has a maximum clamping voltage (VC) of 14.5 V at 41.4 A peak pulse current with a 10/1000 μs waveform. This value is guaranteed per datasheet Table 1 and represents the highest voltage imposed on protected circuitry during worst-case transient events - critical for ensuring compatibility with 12 V logic and analog interfaces.
How does the SMB package of P6SMB10CAHE3/5B compare to SMA or SMC packages?
The SMB (DO-214AA) package of P6SMB10CAHE3/5B measures 4.57 mm × 3.94 mm, smaller than SMC (DO-214AB) but larger than SMA (DO-214AC). It balances surge capability (600 W) with board space efficiency - offering 50 % higher power than SMAJ-series in same footprint, while occupying ~40 % less area than SMCJ-series with comparable VWM.
Does P6SMB10CAHE3/5B require special PCB layout considerations?
Yes, P6SMB10CAHE3/5B requires minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power and thermal performance. Trace width should be ≥15 mils, and ground planes must be solid beneath the device.
