Product details
Overview
P6SMB150CAHM3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 150 V standoff voltage (VWM), 207 V clamping voltage (VC) at 2.9 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects sensitive signal lines and power rails in automotive sensor units, industrial I/O modules, and telecom interface circuits against ESD and inductive switching transients.
For engineers reviewing the P6SMB150CAHM3_A/H datasheet, P6SMB150CAHM3_A/H pinout, P6SMB150CAHM3_A/H application, or P6SMB150CAHM3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, and compatibility with automated SMT assembly on 0.2" × 0.2" copper pads.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical breakdown behavior in both polarities due to its bidirectional construction. Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, critical for suppressing sub-microsecond transients induced by relay switching or lightning surges.
The P6SMB150CAHM3_A/H is thermally rated for TJ = -65 °C to +150 °C and derates linearly above TA = 25 °C per Fig. 2 of the datasheet. Its RθJA = 100 °C/W and RθJL = 20 °C/W define thermal limits under PCB pad-constrained conditions, requiring adherence to the specified 0.2" × 0.2" copper pad layout for full 600 W rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 150 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below system rail. |
| VBR (Breakdown) | 143–158 V at IT = 1 mA - Voltage at which device enters avalanche conduction; ensures tight tolerance for precise overvoltage thresholding. |
| VC (Clamping) | 207 V at IPPM = 2.9 A - Maximum voltage seen by protected circuit during 10/1000 μs transient; determines stress on downstream ICs. |
| PPPM | 600 W - Peak transient energy absorption capacity with 10/1000 μs waveform; validates robustness against IEC 61000-4-5 Level 4 surges. |
| IR (Leakage) | <1.0 μA at VWM - Ultra-low reverse leakage preserves signal integrity and battery life in high-impedance sensor interfaces. |
| TJ max. | +150 °C - Enables operation in under-hood automotive environments and industrial enclosures without thermal derating penalties. |
| AEC-Q101 | Qualified - Confirmed reliability for automotive applications including engine control, ADAS sensors, and body electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ150CA | Same VWM (150 V) and VC (207 V), but lower PPPM (400 W); SMA package (smaller, higher RθJA = 140 °C/W). | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 or repetitive industrial surges. | Select when board space is tighter and surge energy is capped at 400 W-verify thermal margin with actual pad layout. |
| 1.5SMC150CA | Higher PPPM (1500 W), larger SMC package (DO-214AB), same VWM/VC; not AEC-Q101 qualified in standard grade. | Supports higher-energy threats but requires larger PCB area and lacks automotive qualification unless specified HE3/HM3 variant. | Choose for non-automotive industrial systems needing >600 W headroom; confirm HM3 automotive version availability if required. |
Compared with SMAJ150CA and 1.5SMC150CA, the P6SMB150CAHM3_A/H uniquely balances 600 W surge capability, AEC-Q101 qualification, and SMB footprint-making it optimal for space-constrained automotive and industrial designs requiring validated reliability and standardized SMT assembly.

FAQ
What is the clamping voltage of the P6SMB150CAHM3_A/H at its rated peak pulse current?
The P6SMB150CAHM3_A/H has a maximum clamping voltage (VC) of 207 V at a peak pulse current (IPPM) of 2.9 A with a 10/1000 μs waveform. This value is measured under standardized test conditions per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB150CAHM3_A/H maintains this clamping performance across its operational temperature range when mounted on the recommended 0.2" × 0.2" copper pads.
Is the P6SMB150CAHM3_A/H suitable for automotive applications?
Yes, the P6SMB150CAHM3_A/H is AEC-Q101 qualified (indicated by the HM3 suffix), making it suitable for automotive applications including engine control units, ADAS sensors, and body electronics. Its qualification covers high-temperature operating life, thermal cycling, and ESD robustness. The P6SMB150CAHM3_A/H also meets MSL Level 1 for lead-free reflow, supporting automotive manufacturing requirements without special handling.
How does the bidirectional configuration of the P6SMB150CAHM3_A/H affect its placement in circuit design?
The P6SMB150CAHM3_A/H has no polarity marking and functions identically in both directions, allowing placement across any two points requiring symmetrical overvoltage protection-such as differential signal pairs, AC power lines, or uncommitted I/O pins. Unlike unidirectional TVS diodes, the P6SMB150CAHM3_A/H eliminates orientation errors during SMT assembly and simplifies schematic symbol usage. Its bidirectional behavior is confirmed by identical VBR and VC values in both polarities per the datasheet.
What is the thermal resistance specification for the P6SMB150CAHM3_A/H, and how does it impact PCB layout?
The P6SMB150CAHM3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead (RθJL) of 20 °C/W, measured on the minimum recommended 0.2" × 0.2" copper pads per terminal. To achieve full 600 W pulse rating, PCB layout must replicate this pad size and copper weight; reducing pad area increases RθJA and forces derating per Fig. 2 in the datasheet. The P6SMB150CAHM3_A/H's thermal specs are validated only under these defined mounting conditions.
Does the P6SMB150CAHM3_A/H meet RoHS and halogen-free compliance requirements?
Yes, the P6SMB150CAHM3_A/H carries the HM3 suffix, indicating it is halogen-free, RoHS-compliant, and AEC-Q101 qualified. Its molding compound meets UL 94 V-0 flammability rating, and matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards. The P6SMB150CAHM3_A/H also passes JESD 201 Class 2 whisker testing-ensuring long-term reliability in high-vibration and high-humidity environments.
