Product details
Overview
P6SMB10AHE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features 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 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the P6SMB10AHE3_B/I datasheet, P6SMB10AHE3_B/I pinout, P6SMB10AHE3_B/I application, or P6SMB10AHE3_B/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 100 °C/W junction-to-ambient thermal resistance, and compliance with J-STD-020 MSL level 1 reflow profile up to 260 °C.
Technical Context
This TVS diode operates as a voltage-clamping protection device in series with sensitive downstream circuitry, activating when reverse voltage exceeds its 10 V standoff threshold. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<10 μA at VWM), while the low incremental surge resistance enables fast response to ESD and lightning-induced surges.
The P6SMB10AHE3_B/I is rated for 150 °C maximum junction temperature and supports repetitive transient suppression at 0.01 % duty cycle. Its cathode-band marking identifies polarity, and it meets RoHS compliance and AEC-Q101 qualification for automotive-grade reliability under thermal cycling and mechanical stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 8.55 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (Breakdown Voltage) | 9.50–10.5 V at 1 mA test current - precise voltage threshold where avalanche conduction initiates |
| VC (Clamping Voltage) | 14.5 V at 41.4 A IPPM - maximum voltage seen by protected circuit during worst-case 10/1000 μs surge |
| PPPM (Peak Pulse Power) | 600 W - transient energy handling capacity under standardized 10/1000 μs waveform |
| RθJA | 100 °C/W - thermal resistance from junction to ambient air on standard 0.2" × 0.2" copper pads |
| TJ max. | 150 °C - maximum allowable junction temperature for reliable long-term operation |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements including HTRB, HTGB, and temperature cycling |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Reverse-biased terminal | Connected to protected line; conducts avalanche current when voltage exceeds VBR |
| Anode (unmarked end) | Reference/ground terminal | Typically tied to system ground or lower-potential rail to complete clamping path |
Key Features
| Feature | Design Value |
|---|---|

| AEC-Q101 qualification | Validated for under-hood automotive applications including engine control units and body electronics |
| Glass passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift |
| MSL level 1 moisture sensitivity | Allows direct placement into reflow ovens without baking, reducing manufacturing overhead |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on protected ICs compared to higher-ratio alternatives |
Applications
| Automotive Power Supply Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load-dump transients and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input rail and ground to clamp positive-going spikes above 10 V. Use Value: Limits voltage seen by downstream LDOs and microcontrollers to ≤14.5 V during 600 W surges, preventing latch-up or gate oxide damage. |

IC Role / Device Role / Timing Role: Paired with common-mode chokes and bidirectional TVS to handle asymmetrical line-to-ground transients. Use Value: 100 °C/W RθJA allows thermal stability during repeated 10/1000 μs surges without derating in compact line card layouts. |
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/industrial use; lacks automotive stress validation | Select when cost sensitivity outweighs automotive qualification requirements |
| 1.5SMC10A | Higher-power SMC package (1500 W PPPM), same 10 V VWM, but larger footprint and 130 °C/W RθJA | Better for high-energy surges but requires PCB area increase and thermal pad redesign | Choose when system-level surge testing exceeds 600 W and layout permits larger package |
Compared with SMAJ10A-E3/5B and 1.5SMC10A, the P6SMB10AHE3_B/I uniquely balances AEC-Q101 qualification, 600 W surge capability, and SMB footprint - making it optimal for space-constrained automotive modules requiring certified reliability without sacrificing clamping performance.

FAQ
What is the clamping voltage of the P6SMB10AHE3_B/I under maximum surge conditions?
The P6SMB10AHE3_B/I has a maximum clamping voltage (VC) of 14.5 V at 41.4 A peak pulse current (IPPM), measured using the standardized 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is confirmed in the Vishay datasheet revision 09-Jan-2024, page 2.
Is the P6SMB10AHE3_B/I suitable for automotive applications?
Yes, the P6SMB10AHE3_B/I is AEC-Q101 qualified, as indicated by the "HE3_B" suffix per Vishay's ordering information table (page 3). It has passed stress tests including high-temperature reverse bias, temperature cycling, and mechanical shock - making it suitable for under-hood and chassis-mounted automotive electronics.
What does the "_B/I" suffix mean in P6SMB10AHE3_B/I?
The "_B" denotes AEC-Q101 qualification for the P6SMB10AHE3_B/I, while "/I" specifies packaging in 13-inch diameter plastic tape and reel with 3200 units per reel. This format aligns with Vishay's ordering convention shown on page 3 of document 88370 and ensures compatibility with high-speed automated placement equipment.
How does the P6SMB10AHE3_B/I compare to bidirectional TVS diodes like P6SMB10CA?
The P6SMB10AHE3_B/I is unidirectional and intended for DC line protection where polarity is fixed, whereas P6SMB10CA is bidirectional for AC or floating signal lines. The P6SMB10AHE3_B/I offers tighter VBR tolerance (9.50–10.5 V vs. 9.40–10.5 V for the CA version) and is AEC-Q101 qualified - critical for automotive DC power rails.
What is the thermal resistance and maximum junction temperature of the P6SMB10AHE3_B/I?
The P6SMB10AHE3_B/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads, and a maximum junction temperature (TJ max.) of +150 °C. These values are specified in the Thermal Characteristics table (page 3) and define safe continuous power dissipation limits under real-world PCB layout conditions.
