Product details
Overview
P6SMB130CA-M3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 130 V standoff voltage (VWM), 179 V clamping voltage (VC) at 3.4 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects signal lines and power rails in automotive, industrial, and telecom systems against ESD, lightning surges, and inductive switching transients.
For engineers reviewing the P6SMB130CA-M3/5B datasheet, P6SMB130CA-M3/5B pinout, P6SMB130CA-M3/5B application, or P6SMB130CA-M3/5B equivalent, key selection criteria include bidirectional clamping capability, 130 V stand-off rating, 179 V max clamping at 3.4 A, halogen-free RoHS-compliant M3 suffix, and SMB package compatibility with automated SMT assembly.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional CA construction, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 μA at VWM), while the 100 °C/W junction-to-ambient thermal resistance requires careful PCB copper pad design per JEDEC standards.
The device delivers 600 W surge handling under 10/1000 μs waveform with 0.01% duty cycle, and exhibits a temperature coefficient of VBR at +0.107 %/°C - critical for stability across -65 °C to +150 °C operating range. It meets MSL Level 1 and JESD201 Class 2 whisker resistance requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA-T3 | Same VWM (130 V), identical SMB package, but 600 W rating with tighter VC = 179 V (same), different marking and tape/reel packaging | Designed for same board-level surge protection roles; differs only in manufacturer-specific qualification and reel format | Select when sourcing from Microchip/Diodes Inc. supply chain or requiring T3 packaging variant |
| 1.5SMC130CA | Higher package thermal mass (SMC/DO-214AB), 1000 W PPPM rating, same VWM/VC specs, larger footprint (7.11 mm × 6.22 mm) | Used where higher single-pulse energy handling is required and PCB space permits larger package | Choose only if system-level surge testing exceeds 600 W or thermal derating demands lower RθJA |
Compared with P6SMB130CA-M3/5B, SMBJ130CA-T3 offers identical electrical performance in an alternate supply channel, while 1.5SMC130CA trades compact SMB size for higher 1000 W surge capacity and greater thermal robustness - making it suitable only when board area and pulse energy requirements justify the larger footprint.

FAQ
What is the clamping voltage of P6SMB130CA-M3/5B at its rated peak pulse current?
The P6SMB130CA-M3/5B has a maximum clamping voltage (VC) of 179 V at its specified peak pulse current (IPPM) of 3.4 A under a 10/1000 μs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 5.0 mm × 5.0 mm copper pads), and represents the highest voltage imposed on protected circuitry during worst-case surge events. The P6SMB130CA-M3/5B maintains this clamping performance consistently across its operational temperature range.
Is P6SMB130CA-M3/5B suitable for automotive applications?
Yes, P6SMB130CA-M3/5B is halogen-free and RoHS-compliant, and the P6SMB family includes AEC-Q101 qualified variants (e.g., P6SMB130CAHM3_B). While the M3/5B suffix itself denotes commercial-grade halogen-free construction, the underlying die and process are qualified for automotive use - enabling direct substitution with AEC-Q101 versions when required. The P6SMB130CA-M3/5B operates reliably from -65 °C to +150 °C, meeting under-hood thermal requirements.
How does the bidirectional design of P6SMB130CA-M3/5B affect its circuit placement?
The bidirectional design of P6SMB130CA-M3/5B eliminates polarity constraints: it can be placed across any two nodes requiring symmetrical overvoltage protection - such as differential signal pairs (CAN, RS-485), AC power inputs, or floating sensors. Unlike unidirectional TVS diodes, the P6SMB130CA-M3/5B has no cathode band marking and functions identically regardless of orientation. This simplifies layout, reduces BOM count, and avoids assembly errors.
What is the thermal resistance of P6SMB130CA-M3/5B, and how does it impact PCB layout?
The P6SMB130CA-M3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 5.0 mm × 5.0 mm copper pads per terminal. To maintain safe operation under repetitive surges or elevated ambient temperatures, designers must adhere to this pad layout - increasing copper area beyond 5 mm × 5 mm lowers RθJA and improves power dissipation. The P6SMB130CA-M3/5B's RθJL of 20 °C/W further emphasizes the need for low-impedance thermal paths to internal PCB planes.
Does P6SMB130CA-M3/5B meet moisture sensitivity level (MSL) requirements for lead-free reflow?
Yes, P6SMB130CA-M3/5B meets MSL Level 1 per J-STD-020, meaning it is not moisture-sensitive and can be subjected to standard lead-free reflow profiles (peak temperature up to 260 °C) without baking or special handling. This eliminates pre-reflow drying steps, streamlining manufacturing and reducing risk of popcorning or delamination. The M3 suffix confirms halogen-free molding compound and matte tin-plated leads compliant with J-STD-002 solderability standards - fully supporting P6SMB130CA-M3/5B integration into high-yield SMT lines.
