Product details
Overview
P6SMB150A-E3/5B from Vishay General Semiconductor is a unidirectional 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 MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in industrial and telecom power rails.
For engineers reviewing the P6SMB150A-E3/5B datasheet, P6SMB150A-E3/5B pinout, P6SMB150A-E3/5B application, or P6SMB150A-E3/5B equivalent, key selection criteria include unidirectional polarity, 128 μA max reverse leakage at 128 V, -65 °C to +150 °C operating junction range, RoHS-compliant matte tin plating, and MSL Level 1 moisture sensitivity.
Technical Context
This TVS diode operates as a clamping device triggered by voltage exceeding its breakdown threshold (VBR = 143–158 V at 1 mA), rapidly shunting surge energy to ground while limiting downstream voltage to ≤207 V. Its glass-passivated junction ensures stable avalanche behavior and low incremental surge resistance.
Designed for automated SMT placement on PCBs with 5.0 mm × 5.0 mm copper pads per terminal, it delivers repeatable 600 W transient suppression at 0.01% duty cycle and meets JESD201 Class 2 whisker resistance. Thermal resistance is 100 °C/W junction-to-ambient (RθJA) and 20 °C/W junction-to-lead (RθJL).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 128 V - Maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 143–158 V at 1 mA - Precise avalanche initiation range; ensures predictable turn-on during overvoltage events |
| VC (Clamping Voltage) | 207 V at IPPM = 2.9 A - Peak voltage seen by protected circuit during full-rated 600 W transient; determines stress on downstream components |
| PPPM (Peak Pulse Power) | 600 W (10/1000 μs) - Surge energy-handling capability under standardized waveform; validates robustness against IEC 61000-4-5 level 4 threats |

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), VC (207 V), and PPPM (600 W); identical SMB package but lower RθJA (110 °C/W vs. 100 °C/W) | Marginally reduced thermal performance limits sustained surge repetition rate in high-temperature enclosures | Select when cost sensitivity outweighs thermal margin requirements; verify layout cooling for >1 Hz surge frequency |
| 1.5SMC150A | Higher package thermal resistance (RθJA = 125 °C/W); same electrical specs but DO-214AB (SMC) package (larger footprint) | Requires PCB redesign due to 0.280" × 0.210" pad layout; not drop-in compatible with SMB footprints | Choose only if existing design uses SMC footprint or requires higher mechanical robustness for vibration-prone environments |
Compared with SMAJ150A-E3/5B and 1.5SMC150A, P6SMB150A-E3/5B offers optimal balance of thermal performance (100 °C/W RθJA), industry-standard SMB footprint, and AEC-Q101 qualification path-making it preferred for space-constrained industrial and automotive control modules requiring long-term surge endurance.

FAQ
What is the maximum clamping voltage of the P6SMB150A-E3/5B under rated surge conditions?
The P6SMB150A-E3/5B exhibits a maximum clamping voltage (VC) of 207 V when subjected to its rated peak pulse current (IPPM) of 2.9 A using the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay Document Number 88370 and defines the upper voltage limit imposed on protected circuitry during a full 600 W transient event. The P6SMB150A-E3/5B maintains this clamping performance across its specified operating temperature range.
Is the P6SMB150A-E3/5B suitable for automotive applications requiring AEC-Q101 qualification?
The base P6SMB150A-E3/5B is RoHS-compliant and commercial-grade; however, the AEC-Q101 qualified variant is designated as P6SMB150AHE3_B-E3/5B (with "_B" suffix indicating automotive qualification). While the P6SMB150A-E3/5B shares identical electrical and thermal specifications, only the HE3_B version is certified to AEC-Q101. For automotive use, specify the HE3_B suffix to ensure qualification compliance. The P6SMB150A-E3/5B itself is not AEC-Q101 qualified.
What is the reverse leakage current specification for the P6SMB150A-E3/5B at its standoff voltage?
The P6SMB150A-E3/5B has a maximum reverse leakage current (ID) of 1.0 μA when biased at its rated standoff voltage (VWM) of 128 V, tested at TA = 25 °C. This ultra-low leakage ensures minimal power loss and signal distortion in high-impedance sensing and battery-powered circuits. The P6SMB150A-E3/5B maintains leakage below 10 μA up to 150 °C junction temperature per thermal derating curves in the datasheet.
How does the thermal resistance of the P6SMB150A-E3/5B affect its surge handling capability at elevated ambient temperatures?
The P6SMB150A-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W on standard 0.2" × 0.2" copper pads. At ambient temperatures above 25 °C, its peak pulse power rating must be derated per Figure 2 in Document 88370 - e.g., at 75 °C ambient, maximum PPPM drops to ~420 W. This derating directly impacts how frequently the P6SMB150A-E3/5B can sustain 600 W surges without thermal runaway. Proper PCB copper area is essential to maintain P6SMB150A-E3/5B performance.
What packaging format is used for the P6SMB150A-E3/5B, and what is the reel quantity?
The P6SMB150A-E3/5B is supplied in 13-inch diameter plastic tape and reel packaging, with a standard reel quantity of 3200 units per reel (ordering code suffix "5B"). This format supports high-speed automated pick-and-place assembly and complies with EIA-481-D standards. The tape pocket depth and sprocket hole pitch match JEDEC MS-012AC carrier tape specifications, ensuring compatibility with industry-standard feeders. The P6SMB150A-E3/5B reel is labeled with Vishay's traceable lot coding and RoHS compliance marking.
