Product details
Overview
P6SMB10CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 10 V stand-off voltage (VWM), 14.5 V maximum clamping voltage (VC) at 41.4 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial electronics.
For engineers reviewing the P6SMB10CAHE3_A/H datasheet, P6SMB10CAHE3_A/H pinout, P6SMB10CAHE3_A/H application, or P6SMB10CAHE3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, low clamping ratio (VC/VWM = 1.45), MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<10 μA at VWM), while the low incremental surge resistance supports fast energy dissipation during transient events.
The device is rated for 150 °C maximum junction temperature and exhibits a typical thermal resistance of 100 °C/W (junction-to-ambient) under standard PCB mounting conditions. Its 10/1000 μs waveform response delivers repeatable 600 W surge handling at 0.01% duty cycle, with derating applied above TA = 25 °C per Fig. 2 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 10 V - Maximum continuous reverse voltage before significant conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 10.5 V min / 11.6 V max at 1 mA - Voltage at which device enters avalanche breakdown; ensures tight tolerance for predictable clamping onset. |
| VC (Clamping Voltage) | 14.5 V at IPPM = 41.4 A - Maximum voltage seen across terminals during 10/1000 μs surge; critical for ensuring downstream ICs remain within absolute maximum ratings. |
| PPPM (Peak Pulse Power) | 600 W - Surge energy-handling capacity under standardized 10/1000 μs waveform; enables robust protection against ESD, lightning-induced surges, and inductive switching spikes. |
| ID (Reverse Leakage) | ≤10 μA at VWM - Low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max | 150 °C - Maximum allowable junction temperature; supports operation in under-hood automotive and industrial environments. |
| MSL Level | Level 1 (per J-STD-020) - No floor life limitation; suitable for standard reflow without dry-pack requirements. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Bidirectional construction means no polarity marking; terminals are symmetrical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient current path | Both terminals serve as bidirectional surge current entry/exit points; no cathode band marking required. |
Key Features
| Feature | Design Value |

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 VWM (10 V) and VC (14.5 V), but lower PPPM (400 W); SMA package (DO-214AC), slightly larger footprint and higher RθJA (140 °C/W). | Less suited for high-repetition surges or compact thermal layouts; acceptable for consumer-grade non-automotive designs. | Select when cost sensitivity outweighs automotive qualification or 600 W surge margin. |
| 1.5KE10CA | Through-hole TO-204AE (DO-201AE) package; same VWM/VC but higher IPPM (65 A) and PPPM (1500 W); not AEC-Q101 qualified. | Requires PCB through-hole mounting; better for prototyping or legacy board upgrades where SMT is unavailable. | Choose only for non-automotive, non-SMT applications needing higher surge headroom and manual assembly. |
Compared with SMAJ10CA and 1.5KE10CA, P6SMB10CAHE3_A/H uniquely combines AEC-Q101 qualification, SMB footprint compatibility with high-density layouts, and 600 W surge rating - making it the preferred choice for production automotive and industrial SMT designs requiring validated reliability and space efficiency.

FAQ
What is the clamping voltage of P6SMB10CAHE3_A/H at its rated peak pulse current?
The P6SMB10CAHE3_A/H has a maximum clamping voltage (VC) of 14.5 V at its specified peak pulse current (IPPM) of 41.4 A, measured using the 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and confirms the device's ability to limit transient overvoltage to a safe level for downstream 12 V-rated ICs. The P6SMB10CAHE3_A/H datasheet specifies this parameter under "ELECTRICAL CHARACTERISTICS" with test conditions clearly defined.
Is P6SMB10CAHE3_A/H suitable for automotive applications?
Yes, P6SMB10CAHE3_A/H is AEC-Q101 qualified and manufactured with automotive-grade process controls, including whisker-resistant plating (JESD 201 Class 2) and MSL Level 1 handling. Its 150 °C junction rating, robust surge performance, and bidirectional symmetry make it appropriate for engine control, body electronics, and ADAS sensor protection. The "HE3" suffix explicitly denotes AEC-Q101 compliance per Vishay's ordering nomenclature.
How does the bidirectional design of P6SMB10CAHE3_A/H affect circuit layout?
The bidirectional design of P6SMB10CAHE3_A/H eliminates polarity concerns during placement - no cathode band marking is present, and either terminal may connect to signal or ground. This simplifies layout for differential buses (e.g., CAN, RS-485) and AC-coupled lines, reducing risk of assembly error. Layout must still follow Vishay's recommended 0.2" × 0.2" copper pad dimensions to maintain thermal and surge performance per the P6SMB10CAHE3_A/H datasheet.
What is the maximum reverse leakage current for P6SMB10CAHE3_A/H at its stand-off voltage?
The P6SMB10CAHE3_A/H exhibits a maximum reverse leakage current (ID) of 10 μA at its 10 V stand-off voltage (VWM), measured at TA = 25 °C. This low leakage preserves signal integrity in high-impedance sensor interfaces and minimizes quiescent power loss in battery-powered systems. The value is confirmed in the "ELECTRICAL CHARACTERISTICS" table of the official P6SMB10CAHE3_A/H datasheet (Document Number: 88370).
Does P6SMB10CAHE3_A/H require special handling during reflow soldering?
No, P6SMB10CAHE3_A/H is rated MSL Level 1 per J-STD-020 and supports standard lead-free reflow profiles with a maximum peak temperature of 260 °C. It does not require dry packing, baking, or floor-life monitoring. The matte tin-plated leads comply with J-STD-002 and JESD 22-B102, ensuring reliable wetting and joint formation - consistent with standard SMT processes used for the P6SMB10CAHE3_A/H.
