Product details
Overview
P6SMB150AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 150 V standoff voltage (VWM), 171 V minimum breakdown voltage (VBR), 207 V maximum clamping voltage (VC) at 2.9 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive-grade power supply rails and industrial sensor interfaces.
For engineers reviewing the P6SMB150AHM3_A/I datasheet, P6SMB150AHM3_A/I pinout, P6SMB150AHM3_A/I application, or P6SMB150AHM3_A/I equivalent, key selection criteria include clamping performance under repetitive surge events, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and compatibility with automated SMT assembly on SMB (DO-214AA) footprint.
Technical Context
This TVS diode operates as a unidirectional shunt protector, leveraging an avalanche breakdown mechanism to clamp transient overvoltages before they reach downstream ICs or MOSFETs. Its glass-passivated junction ensures stable leakage behavior and long-term reliability under thermal cycling.
Designed for high-reliability environments, P6SMB150AHM3_A/I meets AEC-Q101 stress test requirements and is halogen-free, RoHS-compliant, with MSL Level 1 moisture sensitivity and 260 °C lead-free reflow compatibility. It delivers consistent clamping response within 1 ns and supports repetitive surges at 0.01 % duty cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 128 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC/AC bias margin. |
| VBR (Breakdown Voltage) | 143–158 V at 1 mA - Guaranteed avalanche initiation range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 207 V at IPPM = 2.9 A (10/1000 μs) - Peak voltage seen by protected circuit during worst-case surge; critical for IC survivability. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability per transient event; enables protection against IEC 61000-4-5 Level 4 surges. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; informs derating above 25 °C ambient. |
| TJ max. | 150 °C - Maximum allowable junction temperature; sets upper limit for power dissipation and layout thermal design. |
| IFSM | 100 A - Non-repetitive forward surge current rating (8.3 ms half-sine); validates robustness against accidental polarity reversal. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads; meets UL 94 V-0 flammability rating and J-STD-002 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink node | Connected to protected line; conducts avalanche current to ground during overvoltage events. |
| Anode | Reference/return path | Typically tied to system ground or low-impedance return plane; completes clamping current path. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive power electronics per stress test requirements - supports under-hood and ADAS module deployment. |
| Halogen-free & RoHS-compliant | Meets global environmental compliance mandates without compromising surge robustness or thermal performance. |
| 600 W peak pulse power (10/1000 μs) | Enables single-device protection against severe lightning-induced surges per IEC 61000-4-5, reducing BOM count. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns response), improving protection fidelity for sensitive analog inputs. |
| MSL Level 1, 260 °C peak reflow | Supports standard lead-free SMT processes without pre-baking or special handling - ideal for high-volume manufacturing. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-connected ECUs from load dump and alternator transients. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between power rail and chassis ground. Use Value: Clamps transients up to 207 V while absorbing 600 W pulses - prevents MCU reset or gate oxide damage in power management ICs. |

IC Role / Device Role / Timing Role: Primary-level TVS on DC input bus prior to DC/DC converter stage. Use Value: AEC-Q101 qualification and 150 °C TJ max enable reliable operation in sealed telecom enclosures with limited airflow. |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters for smart home devices. IC Role / Device Role / Timing Role: Unidirectional TVS across output capacitor to suppress flyback spikes and ESD events. Use Value: Low-profile SMB package fits tight board space; halogen-free construction satisfies regional safety certifications (e.g., UL 62368-1). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ150A-E3/5B | Same VWM (128 V), lower PPPM (400 W), non-AEC-Q101, commercial-grade only. | Limited to non-automotive consumer/industrial use; not qualified for automotive temperature cycling or humidity testing. | Select when cost sensitivity outweighs AEC-Q101 requirement and surge threat level is ≤ IEC 61000-4-5 Level 3. |
| 1.5SMC150AHE3_A | Same VWM/VBR/VC specs, but SMC (DO-214AB) package - 2.5 mm wider, higher RθJA (70 °C/W), no AEC-Q101 variant. | Requires larger PCB area; less suitable for dense automotive modules; thermal performance inferior on same pad layout. | Choose only if existing SMC footprint is fixed and AEC-Q101 is not mandated; verify thermal derating at 100 °C ambient. |
Compared with SMAJ150A-E3/5B and 1.5SMC150AHE3_A, P6SMB150AHM3_A/I uniquely combines AEC-Q101 qualification, halogen-free compliance, SMB footprint efficiency, and 600 W surge capacity - making it the preferred choice for next-generation automotive and industrial power protection where reliability, regulatory alignment, and space constraints converge.

FAQ
What is the clamping voltage of P6SMB150AHM3_A/I at its rated peak pulse current?
The P6SMB150AHM3_A/I has a maximum clamping voltage (VC) of 207 V when subjected to its specified peak pulse current of 2.9 A using the 10/1000 μs waveform. This value is measured under standardized test conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads) and represents the upper voltage limit imposed on the protected circuit during a transient event. Designers must ensure downstream components tolerate this clamping level.
Is P6SMB150AHM3_A/I qualified for automotive applications?
Yes, P6SMB150AHM3_A/I is AEC-Q101 qualified - confirmed by Vishay's ordering code suffix "HM3" and documentation revision 09-Jan-2024. The "HM3" denotes halogen-free, RoHS-compliant, and AEC-Q101 qualified construction. It undergoes rigorous stress testing including temperature cycling, humidity bias HAST, and mechanical shock, making it suitable for engine control units, body electronics, and ADAS modules.
What does the "_A/I" suffix mean in P6SMB150AHM3_A/I?
The "_A/I" suffix in P6SMB150AHM3_A/I indicates packaging configuration: "A" denotes the revision code (per Vishay's revision tracking), and "I" specifies 13-inch diameter plastic tape and reel delivery mode with 3200 units per reel. This format aligns with Vishay's standard ordering nomenclature for automotive-grade SMB devices and ensures traceability and handling consistency in SMT production lines.
Can P6SMB150AHM3_A/I be used in bidirectional configurations?
No, P6SMB150AHM3_A/I is a unidirectional TVS diode, as indicated by the "A" (not "CA") suffix in the P6SMB family naming convention. Bidirectional variants use the "CA" suffix (e.g., P6SMB150CA). Using P6SMB150AHM3_A/I in bidirectional signal paths would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit.
What is the thermal resistance of P6SMB150AHM3_A/I, and how does it affect layout design?
P6SMB150AHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimal copper area; increasing pad size or adding thermal vias reduces effective RθJA. For continuous power dissipation or high ambient temperatures (>70 °C), designers must apply derating curves from Figure 2 of the datasheet to maintain TJ ≤ 150 °C.
