Product details
Overview
P6SMB10AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on power and signal 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 automotive and industrial power supplies.
For engineers reviewing the P6SMB10AHE3_A/H datasheet, P6SMB10AHE3_A/H pinout, P6SMB10AHE3_A/H application, or P6SMB10AHE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, SMB (DO-214AA) package compatibility, and clamping performance under repetitive surge conditions.
Technical Context
This TVS diode operates as a voltage-clamping protection device that enters avalanche breakdown when reverse voltage exceeds its breakdown threshold (9.5–10.5 V at 1 mA). Its low incremental surge resistance and fast response time ensure effective suppression of ESD and inductive switching transients before downstream components are damaged.
The device is rated for 150 °C maximum junction temperature, meets J-STD-020 MSL Level 1, and uses glass-passivated chip junction construction for stable long-term reliability. The HE3 suffix confirms RoHS compliance and AEC-Q101 qualification for automotive applications.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A-E3/5B | Same SMB package, 10 V VWM, but rated for 400 W PPPM and not AEC-Q101 qualified. | Limited to commercial-grade consumer or industrial use; lacks automotive qualification documentation. | Select when cost sensitivity outweighs automotive qualification requirements and 400 W surge handling suffices. |
| 1.5SMC10A | Higher 1.5 kW peak power rating, DO-214AB (SMC) package - larger footprint and higher thermal mass. | Used where board space permits larger package and higher energy absorption is required (e.g., mains input stages). | Choose only if PCB layout allows SMC footprint and system-level surge testing exceeds 600 W requirements. |

FAQ
What is the clamping voltage of the P6SMB10AHE3_A/H under a 10/1000 μs surge?
The P6SMB10AHE3_A/H has a maximum clamping voltage (VC) of 14.5 V at 41.4 A peak pulse current under a 10/1000 μs waveform. This value is measured per JEDEC standards and reflects the highest voltage the protected circuit will experience during such a transient event. The P6SMB10AHE3_A/H maintains this clamping performance across its specified operating temperature range and after repeated surge exposures, provided derating guidelines are followed.
Is the P6SMB10AHE3_A/H suitable for automotive applications?
Yes, the P6SMB10AHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive use via the "HE3" suffix and "_A/H" ordering code. It undergoes rigorous stress testing-including temperature cycling, high-temperature reverse bias, and mechanical shock-to meet automotive reliability requirements. The P6SMB10AHE3_A/H is commonly deployed in body control modules, infotainment power supplies, and ADAS sensor interfaces where transient immunity is critical.
What does the "HE3" suffix indicate in P6SMB10AHE3_A/H?
The "HE3" suffix in P6SMB10AHE3_A/H denotes RoHS-compliant construction and AEC-Q101 qualification. It distinguishes this variant from commercial-grade versions (e.g., "E3") and confirms compliance with automotive reliability standards. The "_A/H" portion specifies packaging: "A" indicates the revision level, and "H" denotes 7" tape-and-reel delivery with 750 units per reel. The P6SMB10AHE3_A/H thus combines regulatory compliance, qualification assurance, and logistics readiness.
How does the P6SMB10AHE3_A/H compare to bidirectional TVS diodes like P6SMB10CA?
The P6SMB10AHE3_A/H is unidirectional and intended for DC line protection where polarity is fixed, offering tighter clamping and lower leakage than its bidirectional counterpart P6SMB10CA. Unlike P6SMB10CA-which clamps both polarities and exhibits symmetrical VBR-the P6SMB10AHE3_A/H only conducts in reverse bias, making it ideal for protecting grounded power rails. The P6SMB10AHE3_A/H also carries AEC-Q101 certification, whereas P6SMB10CA variants require separate qualification verification.
What is the thermal resistance of the P6SMB10AHE3_A/H, and how does it affect layout design?
The P6SMB10AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W. These values assume mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain safe junction temperatures under sustained power dissipation, PCB layout must provide adequate copper area and avoid thermal bottlenecks. The P6SMB10AHE3_A/H's RθJL enables efficient heat transfer to adjacent traces or planes, supporting reliable operation up to 150 °C TJ.
