Product details
Overview
P6SMB10AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 600 W peak pulse power (10/1000 μs), 14.5 V maximum clamping voltage at 41.4 A peak pulse current, and 8.55 V stand-off voltage - deployed to protect MOSFETs, ICs, and sensor signal lines against inductive switching transients in industrial and automotive electronics.
For engineers reviewing the P6SMB10AHE3_B/H datasheet, P6SMB10AHE3_B/H pinout, P6SMB10AHE3_B/H application, or P6SMB10AHE3_B/H equivalent, this AEC-Q101 qualified TVS offers verified clamping performance, low incremental surge resistance, and RoHS-compliant matte tin-plated terminals suitable for automated SMT assembly and high-reliability board-level ESD/surge protection.
Technical Context
The P6SMB10AHE3_B/H operates as a unidirectional avalanche diode with a specified breakdown voltage range of 9.50–10.5 V at 1.0 mA test current, enabling precise overvoltage thresholding. Its 14.5 V clamping voltage at 41.4 A IPPM ensures predictable voltage limiting during transient events.
Designed for surface-mount implementation on 0.2" × 0.2" copper pads, it delivers thermal resistance of 100 °C/W (junction-to-ambient) and supports operating junction temperatures from –65 °C to +150 °C - validated under MSL Level 1 per J-STD-020 at 260 °C peak reflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 600 W - sustains high-energy transients without failure in automotive and industrial surge environments |
| Stand-off Voltage (VWM) | 8.55 V - maximum continuous reverse voltage before significant leakage; sets safe operating margin below breakdown |
| Breakdown Voltage (VBR) | 9.50–10.5 V at 1.0 mA - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| Clamping Voltage (VC) | 14.5 V at 41.4 A IPPM - limits downstream circuit voltage during surge, protecting sensitive 12 V rail components |
| Package | SMB (DO-214AA) - standardized surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height for compact PCB layout |
| AEC-Q101 Qualified | Yes - certified for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock testing |
| RoHS Compliance | Yes - lead-free, halogen-free compliant per Vishay HE3 suffix designation |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional polarity with cathode band marking. Dimensions: 5.59 mm × 4.06 mm × 2.20 mm (L × W × H). Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal per Vishay specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to protected circuit ground or low-side reference | Completes conduction path during reverse-transient clamping; must be routed to lowest-impedance ground plane |
| Cathode | Marked end (band); reverse-biased terminal connected to protected line (e.g., 12 V supply or signal trace) | Acts as transient-sensing node; voltage rise above VWM triggers avalanche conduction to shunt energy to ground |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power rating | Enables robust protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) without derating in standard layouts |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on downstream ICs - critical for 12 V logic and automotive microcontrollers |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking, reducing manufacturing overhead |
| Glass passivated junction | Ensures stable leakage current (<10 μA at VWM) and long-term reliability under thermal cycling |
| AEC-Q101 qualification (HE3_B/H) | Validates suitability for automotive powertrain, body control, and ADAS modules requiring zero-defect operation |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Protection |

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, 600 W rating, but VWM = 8.55 V, VC = 14.5 V - identical clamping, lower TJ max (150 °C same), no AEC-Q101 qualification | Commercial-grade only; not approved for automotive production or extended-temperature industrial use | Select when AEC-Q101 is not required and cost optimization is prioritized over automotive qualification |
| 1.5SMC10A | Higher-power SMC package (1500 W), same VWM/VC specs, larger footprint (7.11 mm × 6.22 mm), RθJA = 30 °C/W vs. 100 °C/W | Used where higher single-pulse energy absorption is needed, but requires PCB area increase and thermal pad redesign | Choose for legacy designs needing higher surge margin or where existing SMC footprint is standardized |
Compared with SMAJ10A and 1.5SMC10A, P6SMB10AHE3_B/H uniquely combines AEC-Q101 qualification, SMB footprint compatibility, and verified 600 W clamping performance - making it the preferred choice for new automotive and high-reliability industrial designs where qualification and space constraints are co-driven selection criteria.

FAQ
What is the maximum clamping voltage of the P6SMB10AHE3_B/H under specified test conditions?
The P6SMB10AHE3_B/H has a maximum clamping voltage (VC) of 14.5 V when subjected to its rated peak pulse current of 41.4 A using a 10/1000 μs waveform. This value is measured at TA = 25 °C with devices mounted on 0.2" × 0.2" copper pads per Vishay's test condition. The clamping voltage directly determines the peak overvoltage seen by protected circuitry, making it a critical parameter for ensuring downstream IC survivability in surge events.
Is the P6SMB10AHE3_B/H suitable for automotive applications?
Yes, the P6SMB10AHE3_B/H is AEC-Q101 qualified, as indicated by the "HE3_B" suffix, confirming compliance with stress tests including temperature cycling, high-temperature operating life, and mechanical shock. It is explicitly intended for automotive body electronics, infotainment power rails, and sensor interface protection where zero-defect reliability and extended temperature operation (–65 °C to +150 °C) are required - unlike commercial-grade variants such as SMAJ10A.
What does the "_B/H" suffix in P6SMB10AHE3_B/H signify?
The "_B" denotes AEC-Q101 qualification for the P6SMB10AHE3_B/H series, while "/H" specifies packaging in 7" diameter plastic tape and reel with a base quantity of 750 units. This ordering code aligns with Vishay's standard nomenclature where "HE3" indicates RoHS-compliant and AEC-Q101 qualified construction, and "/H" identifies the reel size and orientation - essential for SMT line setup and inventory planning.
How does the P6SMB10AHE3_B/H compare to bidirectional TVS diodes like P6SMB10CA?
The P6SMB10AHE3_B/H is unidirectional and features a cathode band for polarity identification, whereas P6SMB10CA is bidirectional with no polarity marking and symmetric clamping in both directions. Unidirectional operation allows tighter VWM control (8.55 V vs. 8.55 V for bidirectional), but requires correct orientation in-circuit. Bidirectional types are used where AC signal lines or differential buses need protection without polarity concerns - the P6SMB10AHE3_B/H is selected specifically for DC rail protection where polarity is fixed.
What is the thermal resistance and maximum junction temperature of the P6SMB10AHE3_B/H?
The P6SMB10AHE3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" copper pads, and a maximum operating junction temperature (TJ) of +150 °C. Its junction-to-lead resistance (RθJL) is 20 °C/W. These values define safe power dissipation limits under sustained surge duty cycles and ensure compatibility with standard FR-4 PCB layouts without additional heatsinking.
