Product details
Overview
P6SMB130A-M3/5B 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 130 V standoff voltage (VWM), 179 V maximum clamping voltage at 3.4 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 industrial power supplies.
For engineers reviewing the P6SMB130A-M3/5B datasheet, P6SMB130A-M3/5B pinout, P6SMB130A-M3/5B application, or P6SMB130A-M3/5B equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance under surge conditions, and halogen-free RoHS-compliant sourcing status per Vishay's M3 suffix specification.
Technical Context
The P6SMB130A-M3/5B operates as a unidirectional avalanche diode with cathode-band polarity marking, optimized for fast transient response (<1 ns) and low incremental surge resistance. Its breakdown voltage is specified at 124–137 V (min/max) with 1 mA test current, and it maintains stable clamping up to 150 °C junction temperature.
Thermal design relies on its RθJA of 100 °C/W (typical, no heatsink) and RθJL of 20 °C/W, requiring PCB copper pad layout per DO-214AA footprint (0.2" × 0.2" pads). It meets J-STD-020 MSL Level 1 and supports automated SMT placement without reflow concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 111 V - Maximum continuous reverse voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 124–137 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping) | 179 V at IPPM = 3.4 A - Peak voltage seen by protected circuit during 10/1000 μs surge; critical for downstream device voltage rating margin. |
| PPPM | 600 W - Peak pulse power handling with 0.01% duty cycle; enables robust protection against lightning-induced or inductive-switching transients. |
| IFSM | 100 A - Non-repetitive forward surge rating (8.3 ms half-sine); supports temporary fault-current exposure in DC power rails. |
| TJ max | 150 °C - Maximum junction temperature; sets upper limit for thermal design and ambient operating envelope. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 0.220" × 0.130" body; compatible with high-volume pick-and-place and reflow processes. |

IC Role / Device Role / Timing Role: Rail-to-ground TVS on 12 V or 15 V auxiliary supply, triggered by commutation spikes exceeding 111 V standoff. Use Value: Fast response (<1 ns) and low Rsurge prevent latch-up in high-speed gate drivers, avoiding catastrophic IGBT failure during stall conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130A-E3/5B | Same VWM (111 V), but lower PPPM (400 W) and higher VC (193 V at 3.1 A); SMA package (smaller footprint, higher RθJA). | Limited to lower-energy transients; unsuitable where 600 W headroom is required per IEC 61000-4-5 Level 4 testing. | Select P6SMB130A-M3/5B when full 600 W rating and SMB mechanical robustness are mandatory for industrial environments. |
| 1.5SMC130A | Identical electrical specs (VWM, VBR, VC, PPPM) but in larger SMC (DO-214AB) package; higher thermal mass, RθJA ≈ 60 °C/W. | Better thermal performance under sustained surge repetition, but requires larger PCB area and incompatible with SMB-reflow profiles. | Choose P6SMB130A-M3/5B for space-constrained designs needing halogen-free compliance and MSL-1 reflow compatibility. |
Compared with SMAJ130A-E3/5B and 1.5SMC130A, the P6SMB130A-M3/5B uniquely balances 600 W surge capacity, SMB footprint efficiency, halogen-free construction, and MSL Level 1 process readiness - making it optimal for high-density industrial and automotive control boards where reliability, compliance, and manufacturability intersect.

FAQ
What is the maximum clamping voltage of the P6SMB130A-M3/5B under rated surge conditions?
The P6SMB130A-M3/5B has a maximum clamping voltage (VC) of 179 V at 3.4 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88370 and defines the upper voltage limit imposed on protected circuits during standardized surge events. The P6SMB130A-M3/5B maintains this clamping performance across its full operating temperature range up to 150 °C.
Does the P6SMB130A-M3/5B meet automotive qualification standards?
The base P6SMB130A-M3/5B is not AEC-Q101 qualified; it is a commercial-grade halogen-free part. However, Vishay offers the AEC-Q101 variant as P6SMB130AHM3_B/5B (with "_B" revision suffix), which shares identical electrical specs but adds automotive stress testing and traceability. The P6SMB130A-M3/5B itself is widely used in non-safety-critical automotive subsystems where full qualification is not mandated.
What is the meaning of the "M3" and "5B" suffixes in P6SMB130A-M3/5B?
In P6SMB130A-M3/5B, "M3" denotes halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance, while "5B" specifies packaging in a 13-inch diameter plastic tape-and-reel format containing 3200 units. This differs from "52" (7-inch reel, 750 units) and ensures compatibility with high-volume SMT assembly lines requiring extended reel lengths.
How does the thermal resistance of the P6SMB130A-M3/5B affect PCB layout?
The P6SMB130A-M3/5B has a typical RθJA of 100 °C/W with standard 0.2" × 0.2" copper pads per terminal. To maintain TJ ≤ 150 °C under 5.0 W steady-state dissipation, designers must ensure adequate copper area and avoid thermal isolation. The P6SMB130A-M3/5B datasheet recommends minimum pad dimensions of 5.59 mm × 5.21 mm per terminal for optimal thermal performance.
Can the P6SMB130A-M3/5B be used in bidirectional configurations?
No - the P6SMB130A-M3/5B is strictly unidirectional, indicated by the "A" suffix and cathode band marking. For bidirectional operation, Vishay specifies the P6SMB130CA-M3/5B variant, which has symmetric breakdown in both polarities and no polarity marking. Using the P6SMB130A-M3/5B in reverse-biased AC applications would result in unintended conduction and potential failure.
