Product details
Overview
P6SMB150CA-M3/5B 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), 165 V minimum breakdown voltage (VBR), and 207 V maximum clamping voltage (VC) at 2.9 A peak pulse current (IPPM), delivering 600 W peak pulse power with 10/1000 μs waveform for protecting MOSFETs and sensor signal lines in industrial power supplies.
For engineers reviewing the P6SMB150CA-M3/5B datasheet, P6SMB150CA-M3/5B pinout, P6SMB150CA-M3/5B application, or P6SMB150CA-M3/5B equivalent, key selection criteria include bidirectional clamping capability, 207 V VC under 2.9 A transient stress, halogen-free RoHS-compliant M3 suffix, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VWM = 128 V, VBR(min) = 143 V, and VC = 207 V at IPPM = 2.9 A - enabling robust protection of AC-coupled or differential signal paths without polarity sensitivity. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns) to ESD and lightning-induced transients.
Thermal performance is defined by RθJA = 100 °C/W and RθJL = 20 °C/W, supporting operation from –65 °C to +150 °C junction temperature. The device meets J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance, confirming suitability for high-reliability commercial PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 128 V - maximum continuous reverse voltage before clamping begins; defines safe operating margin below system rail. |
| VBR (Breakdown Voltage) | 143–158 V at 1 mA - sharp avalanche onset threshold ensuring predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 207 V at 2.9 A (10/1000 μs) - limits transient voltage seen by protected ICs to safe levels during surge conditions. |
| PPPM (Peak Pulse Power) | 600 W - energy-handling capacity for standardized lightning/surge immunity per IEC 61000-4-5. |
| ID (Reverse Leakage) | <1.0 μA at 128 V - negligible standby current that avoids loading sensitive analog or low-power circuits. |
| TJ max. | +150 °C - enables use in enclosed industrial enclosures or near heat-generating components without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150CA-T3 | Same VWM (128 V), VC = 207 V, but rated for 600 W with tighter VBR tolerance (143–158 V vs. 143–158 V); identical SMB package. | Designed for higher-volume consumer applications; lacks AEC-Q101 qualification path unlike P6SMB150CA-M3/5B's M3 suffix. | Select SMBJ150CA-T3 when cost-sensitive commercial designs require identical electrical specs without automotive qualification. |
| 1.5SMC150CA | Higher package thermal resistance (RθJA = 125 °C/W vs. 100 °C/W); same VWM/VC but lower IPPM (2.6 A vs. 2.9 A) due to larger SMC (DO-214AB) footprint. | Requires more PCB area (7.11 mm × 6.22 mm vs. 5.59 mm × 4.06 mm); suited for less space-constrained industrial modules. | Choose 1.5SMC150CA only if existing layout accommodates SMC and higher thermal margin is needed for sustained surge duty cycles. |

FAQ
What is the clamping voltage of P6SMB150CA-M3/5B at its rated peak pulse current?
The P6SMB150CA-M3/5B has a maximum clamping voltage (VC) of 207 V when subjected to its specified peak pulse current of 2.9 A with a 10/1000 μs waveform. This value is measured under standardized test conditions per JEDEC standards and ensures downstream components see no more than 207 V during surge events. The P6SMB150CA-M3/5B maintains this clamping performance across its full operating temperature range of –65 °C to +150 °C.
Is P6SMB150CA-M3/5B suitable for automotive applications?
P6SMB150CA-M3/5B is halogen-free and RoHS-compliant but not AEC-Q101 qualified in this specific M3/5B configuration. Automotive-grade variants exist under HE3/HM3 suffixes (e.g., P6SMB150CAHM3_B), which include full AEC-Q101 testing. For non-safety-critical automotive subsystems where qualification is not mandated, the P6SMB150CA-M3/5B may be used - however, designers must validate its performance per ISO 7637-2 and IEC 61000-4-5 in their specific application. The P6SMB150CA-M3/5B itself does not carry AEC-Q101 certification.
How does the bidirectional design of P6SMB150CA-M3/5B affect PCB layout?
The bidirectional nature of P6SMB150CA-M3/5B eliminates polarity marking and orientation constraints: either terminal functions as anode or cathode depending on transient direction, allowing unrestricted placement on PCBs. No silkscreen polarity indicator is needed, simplifying pick-and-place programming and reducing assembly errors. Layout requires only two 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay P6SMB datasheet - and the P6SMB150CA-M3/5B performs identically regardless of mounting rotation.
What is the maximum steady-state power dissipation for P6SMB150CA-M3/5B?
The P6SMB150CA-M3/5B has a maximum steady-state power dissipation (PD) of 5.0 W when mounted on an infinite heatsink at TA = 50 °C. This rating reflects continuous DC or low-frequency reverse leakage power handling - not transient surge capability. In typical applications, PD remains well below 100 mW due to sub-μA leakage at VWM (128 V), so thermal design focuses on transient energy absorption rather than steady-state cooling. The P6SMB150CA-M3/5B's RθJA of 100 °C/W confirms suitability for natural-convection environments without forced airflow.
Does P6SMB150CA-M3/5B meet moisture sensitivity level requirements for lead-free reflow?
Yes, P6SMB150CA-M3/5B meets MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C - fully compatible with standard lead-free soldering profiles. No dry-packaging or baking is required prior to assembly, streamlining high-volume SMT production. This MSL rating is verified through accelerated moisture exposure testing and applies to the M3 suffix variant specifically. The P6SMB150CA-M3/5B can be stored indefinitely at ambient conditions without moisture-related assembly risks.
