Product details
Overview
P6SMB10AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping transient overvoltages 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 rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial electronics.
For engineers reviewing the P6SMB10AHE3_A/I datasheet, P6SMB10AHE3_A/I pinout, P6SMB10AHE3_A/I application, or P6SMB10AHE3_A/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and real-world protection use cases - all critical for ESD/surge design validation and BOM selection.
Technical Context
The P6SMB10AHE3_A/I operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its 9.5–10.5 V breakdown range (VBR at 1 mA). Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, ensuring precise clamping during lightning-induced or inductive-switching transients.
Rated for 150 °C max junction temperature and compliant with J-STD-020 MSL Level 1 (260 °C reflow peak), it supports automated SMT assembly. The cathode band marking identifies polarity, and its SMB package provides 5.0 mm × 5.0 mm copper pad thermal performance per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 8.55 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working margin. |
| VBR (Breakdown Voltage) | 9.50–10.5 V at 1 mA - Precise avalanche initiation threshold; ensures repeatable turn-on under transient stress. |
| VC (Clamping Voltage) | 14.5 V at 41.4 A IPPM - Peak voltage seen by protected circuit during 600 W surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 600 W with 10/1000 μs waveform - Sustains high-energy transients without failure; validated at 0.01% duty cycle. |
| ID (Reverse Leakage) | 10 μA at 8.55 V - Minimal standby power loss and signal integrity impact in always-on circuits. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient; requires ≥5.0 mm × 5.0 mm copper pads for rated power handling. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness per AEC standard. |

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 | Same SMB package, 10 V VWM, but lower PPPM (400 W) and higher VC (16.7 V at 24.7 A); non-AEC-Q101. | Limited to commercial-grade consumer/industrial use; insufficient for automotive load-dump immunity. | Select when cost sensitivity outweighs automotive qualification and higher surge margin. |
| 1.5SMC10A | Higher-power SMC package (1500 W PPPM), same 10 V VWM, but larger footprint (7.11 mm × 6.22 mm) and higher VC (17.0 V). | Used where board space allows and higher single-pulse energy absorption is required (e.g., telecom central office). | Choose when surge energy exceeds 600 W and PCB layout accommodates SMC footprint. |
Compared with SMAJ10A and 1.5SMC10A, the P6SMB10AHE3_A/I uniquely balances AEC-Q101 qualification, 600 W surge capability, and compact SMB footprint - making it optimal for space-constrained automotive modules requiring validated reliability.

FAQ
What is the clamping voltage of the P6SMB10AHE3_A/I under maximum rated surge current?
The P6SMB10AHE3_A/I has a maximum clamping voltage (VC) of 14.5 V when subjected to its rated peak pulse current of 41.4 A (10/1000 μs waveform). This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB10AHE3_A/I maintains this clamping performance across its specified operating temperature range and is validated per JEDEC and AEC-Q101 test protocols.
Is the P6SMB10AHE3_A/I suitable for automotive applications?
Yes, the P6SMB10AHE3_A/I is AEC-Q101 qualified, as indicated by the "HE3" suffix and documented in Vishay's official datasheet revision 09-Jan-2024. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD verification - making it appropriate for under-hood and cabin electronics such as body control modules and sensor signal conditioning. The P6SMB10AHE3_A/I meets automotive reliability requirements without derating in standard mounting configurations.
What does the "_A/I" suffix mean in P6SMB10AHE3_A/I?
The "_A/I" suffix in P6SMB10AHE3_A/I denotes packaging configuration: "A" indicates the base part is unidirectional, and "I" specifies 13-inch diameter plastic tape-and-reel delivery (3200 units per reel). This aligns with Vishay's ordering nomenclature where "H" = 7-inch reel (750 units) and "I" = 13-inch reel. The P6SMB10AHE3_A/I is RoHS-compliant, halogen-free, and AEC-Q101 qualified - confirmed in the manufacturer's ordering information table.
How does the thermal performance of the P6SMB10AHE3_A/I compare to similar SMB TVS diodes?
The P6SMB10AHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 5.0 mm × 5.0 mm copper pads - matching industry-standard SMB thermal benchmarks. This value assumes minimum recommended pad layout per JEDEC; reducing pad area increases RθJA and limits power dissipation. Unlike some competing SMB TVS parts, the P6SMB10AHE3_A/I sustains full 600 W pulse rating under these conditions and retains specification stability up to 150 °C junction temperature.
Can the P6SMB10AHE3_A/I be used in bidirectional configurations?
No, the P6SMB10AHE3_A/I is strictly unidirectional, as confirmed by its "A" suffix (vs. "CA" for bidirectional variants like P6SMB10CA) and cathode-band polarity marking. Bidirectional operation would require reverse voltage tolerance in both directions - a feature absent in this part. Using the P6SMB10AHE3_A/I in bidirectional signal paths risks catastrophic failure during positive transients on the anode. For such applications, select the P6SMB10CA or equivalent bidirectional variant.
