Product details
Overview
P6SMB10AHM3_B/H 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 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 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6SMB10AHM3_B/H datasheet, P6SMB10AHM3_B/H pinout, P6SMB10AHM3_B/H application, or P6SMB10AHM3_B/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (HM3 suffix), 100 °C/W junction-to-ambient thermal resistance, and compatibility with automated SMT assembly on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a clamping device that enters avalanche breakdown when reverse voltage exceeds its 10.5 V minimum breakdown voltage (VBR) at 1 mA test current. Its low incremental surge resistance ensures stable clamping performance under repetitive 0.01% duty cycle transients.
Designed for unidirectional protection only, it exhibits 8.55 V standoff voltage (VWM), ≤10 μA reverse leakage at VWM, and a temperature coefficient of VBR at +0.073 %/°C - enabling predictable voltage threshold behavior across -65 °C to +150 °C operating junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff) | 8.55 V - maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping threshold |
| VBR (Breakdown) | 9.50–10.5 V at 1 mA - precise avalanche initiation range; ensures consistent turn-on during ESD or load-switching transients |
| VC (Clamping) | 14.5 V at 41.4 A IPPM - peak voltage seen by protected circuit during 10/1000 μs surge; determines downstream component stress level |
| PPPM | 600 W - peak transient energy absorption capacity with standard 10/1000 μs waveform; supports robust industrial surge immunity |
| TJ max | +150 °C - maximum junction temperature; enables operation in under-hood automotive or high-ambient industrial environments |
| RθJA | 100 °C/W - thermal resistance from junction to ambient air on standard pad layout; informs heatsinking requirements for sustained surge duty |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Cathode indicated by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected line; carries forward current during fault conditions |
| Cathode | Avalanche clamping terminal | Connected to higher-potential side; initiates controlled breakdown when reverse voltage exceeds VBR |
Key Features
| Feature | Design Value |

| 600 W peak pulse power | Withstands IEC 61000-4-5 Level 4 surges (4 kV) without degradation when mounted per recommended 0.2" × 0.2" copper pads |
| Glass passivated junction | Enhances long-term stability and moisture resistance - critical for extended service life in humid or thermally cycled environments |
| MSL Level 1 | Unlimited floor life at ≤30 °C/60% RH; compatible with standard reflow profiles up to 260 °C peak temperature |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Suppresses load-dump transients (up to 35 V, 100 ms) on 12 V battery-fed ECUs in passenger vehicles. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between power input and ground, responding within <1 ns to limit rail voltage excursion. Use Value: Prevents latch-up or permanent damage to microcontrollers and CAN transceivers by holding rail voltage ≤14.5 V during surge events. |
Use Scenario: Shields analog output lines (e.g., 4–20 mA current loop) from ESD and inductive kickback in factory automation sensors. IC Role / Device Role / Timing Role: Standoff-clamp TVS connected across signal and return path, absorbing ±8 kV contact ESD per IEC 61000-4-2. Use Value: Maintains signal integrity and prevents ADC saturation or op-amp input stage damage without adding series impedance or capacitance. |
| Consumer Power Adapter Input Stage | Telecom Line Card Surge Protection |
Use Scenario: Protects primary-side switching controllers in AC/DC adapters against lightning-induced surges entering via mains input. IC Role / Device Role / Timing Role: Front-end unidirectional TVS placed between bridge rectifier output and bulk capacitor, clamping fast-rising transients. Use Value: Enables compliance with UL 62368-1 surge withstand requirements while minimizing footprint versus multi-stage protection schemes. |
Use Scenario: Guards Ethernet PHY interface circuits on telecom line cards against induced surges from nearby power cables or lightning coupling. IC Role / Device Role / Timing Role: Secondary-side TVS on isolated DC bias rails feeding magnetics or PHY ICs, activated after isolation barrier. Use Value: Provides coordinated protection with primary-side MOVs while avoiding ground-loop issues - critical for common-mode surge suppression. |
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-E3/52 | Same VWM (8.55 V), VC (14.5 V), and PPPM (600 W); SMA package (DO-214AC), slightly larger footprint and higher RθJA (140 °C/W) | Less suitable for high-density automotive PCBs where SMB's smaller size and lower thermal resistance are critical | Select SMAJ10A-E3/52 only if existing layout uses SMA or requires RoHS-compliant commercial grade without AEC-Q101 |
| 1.5SMC10A | Same electrical specs but SMC (DO-214AB) package; 1.5 kW rating, larger body, higher IFSM (200 A), RθJA = 60 °C/W | Better for high-repetition surge environments (e.g., motor drives), but incompatible with SMB land patterns and automated placement reels | Choose 1.5SMC10A only when thermal budget allows larger package and board space permits SMC footprint |

FAQ
What is the polarity configuration of P6SMB10AHM3_B/H?
P6SMB10AHM3_B/H is a unidirectional TVS diode, meaning it conducts only in reverse-bias avalanche mode to clamp positive transients on the cathode side. The band marking on the SMB package identifies the cathode terminal, and no conduction occurs in forward direction beyond typical diode drop. This configuration is essential for DC power rail protection where polarity is fixed.
Does P6SMB10AHM3_B/H meet automotive qualification standards?
Yes, P6SMB10AHM3_B/H is AEC-Q101 qualified, as confirmed by the HM3 suffix and documentation in Vishay's P6SMB datasheet revision 09-Jan-2024. This qualification covers stress tests including HTGB, HTRB, TCT, and mechanical shock - validating its suitability for under-hood and chassis-mounted automotive electronics.
What is the maximum clamping voltage of P6SMB10AHM3_B/H under surge conditions?
The maximum clamping voltage (VC) of P6SMB10AHM3_B/H is 14.5 V at 41.4 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is guaranteed across temperature and represents the highest voltage imposed on the protected circuit during standardized surge testing - critical for ensuring downstream ICs remain within absolute maximum ratings.
How does the SMB (DO-214AA) package of P6SMB10AHM3_B/H compare thermally to larger packages?
P6SMB10AHM3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W on standard 0.2" × 0.2" copper pads, which is lower than SMA (140 °C/W) but higher than SMC (60 °C/W). This makes it suitable for moderate-duty surge applications with limited board area, while still supporting reliable operation up to +150 °C junction temperature.
Is P6SMB10AHM3_B/H compatible with lead-free reflow processes?
Yes, P6SMB10AHM3_B/H is rated for lead-free reflow with a maximum peak temperature of 260 °C, meeting J-STD-020 MSL Level 1 requirements. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102, ensuring robust solder joint formation without voiding or dewetting in standard profile reflow ovens.
