Product details
Overview
P6SMB130CA-E3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, rated for 130 V standoff voltage (VWM), 179 V maximum clamping voltage (VC) at 3.4 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with a 10/1000 μs waveform. It protects sensitive signal lines in automotive sensor units, industrial I/O interfaces, and telecom power rails against ESD and inductive switching transients.
For engineers reviewing the P6SMB130CA-E3/5B datasheet, P6SMB130CA-E3/5B pinout, P6SMB130CA-E3/5B application, or P6SMB130CA-E3/5B equivalent, key selection criteria include bidirectional clamping symmetry, low thermal resistance (RθJL = 20 °C/W), AEC-Q101 qualification eligibility, and compatibility with automated SMT placement on standard 0.2" × 0.2" copper pads.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM), but switches to low-impedance conduction within <1 ns when transient voltage exceeds its breakdown threshold (VBR = 124–137 V). Its bidirectional architecture ensures symmetrical clamping in both polarities without polarity marking.
The device uses a glass-passivated silicon junction, enabling stable performance across -65 °C to +150 °C operating temperature range and meeting J-STD-020 MSL Level 1 (260 °C peak reflow). Its 600 W PPPM rating is specified at TA = 25 °C with derating above that temperature per Figure 2 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 111 V - Maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping onset. |
| VBR (Breakdown Voltage) | 124–137 V at IT = 1 mA - Voltage at which device transitions from high- to low-impedance state; determines transient triggering threshold. |
| VC (Clamping Voltage) | 179 V at IPPM = 3.4 A - Maximum voltage seen by protected circuit during 10/1000 μs surge; critical for IC-level overvoltage margining. |
| PPPM (Peak Pulse Power) | 600 W - Surge energy handling capability under standardized 10/1000 μs waveform; enables protection against IEC 61000-4-5 Level 4 surges. |
| ID (Reverse Leakage) | 1.0 μA max at VWM - Ensures minimal standby power loss and signal integrity in high-impedance sensor or data lines. |
| TJ max | +150 °C - Junction temperature limit defining maximum ambient + self-heating budget in thermally constrained PCB layouts. |
| RθJL | 20 °C/W - Thermal resistance from junction to lead; supports reliable power dissipation with minimal copper pad area (0.2" × 0.2"). |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); matte tin-plated leads, solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; common node in bidirectional clamping | Connected to line being protected; forms symmetrical clamp path with cathode during either polarity transient. |
| Cathode | Current exit terminal in forward bias; common node in bidirectional clamping | Connected to reference plane (e.g., ground or supply rail); completes low-impedance surge path during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines (e.g., RS-485, CAN, USB D+/D−) without polarity concerns. |
| 600 W peak pulse power | Supports robust immunity to IEC 61000-4-5 combination wave surges up to 4 kV (open-circuit)/2 kA (short-circuit) with proper PCB layout. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns response), preserving timing margins in high-speed digital interfaces. |
| AEC-Q101 qualification option | HE3/HM3 variants available for automotive applications; P6SMB130CA-E3/5B itself is commercial-grade but shares identical die and construction. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking; compatible with high-throughput SMT assembly lines. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130CA | Same VWM/VBR/VC specs, but SMA (DO-214AC) package (smaller footprint: 4.5 × 2.7 mm vs. SMB's 4.6 × 3.9 mm); RθJA = 125 °C/W vs. 100 °C/W for P6SMB130CA-E3/5B. | Preferred where board space is constrained and thermal margin allows higher junction rise; less suitable for high-repetition surges in compact enclosures. | Select SMAJ130CA only if PCB real estate is critical and peak ambient temperature remains ≤60 °C. |
| SMCJ130CA | Higher PPPM (1500 W), larger SMC (DO-214AB) package (7.1 × 6.2 mm); same VWM/VBR/VC but lower clamping ratio (VC/VBR ≈ 1.33 vs. 1.39 for P6SMB130CA-E3/5B). | Used in primary-side AC/DC input protection or high-energy industrial drives where 600 W is insufficient; not drop-in due to footprint and height mismatch. | Choose SMCJ130CA when surge energy exceeds 600 W requirements and mechanical clearance permits larger package. |
Compared with SMAJ130CA and SMCJ130CA, the P6SMB130CA-E3/5B delivers optimal balance of surge robustness, thermal performance, and SMT manufacturability in mid-power applications-offering 600 W clamping with superior thermal resistance (RθJL = 20 °C/W) and industry-standard SMB footprint compatibility.

FAQ
What is the clamping voltage of the P6SMB130CA-E3/5B at its rated peak pulse current?
The P6SMB130CA-E3/5B has a maximum clamping voltage (VC) of 179 V at a peak pulse current (IPPM) of 3.4 A, measured using the standardized 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuits during surge events. The P6SMB130CA-E3/5B maintains this clamping performance due to its low incremental surge resistance and glass-passivated junction design.
Is the P6SMB130CA-E3/5B suitable for automotive applications?
The P6SMB130CA-E3/5B is RoHS-compliant and built on the same die as AEC-Q101-qualified variants (e.g., P6SMB130CAHE3_B), but the E3/5B suffix denotes commercial-grade qualification only. For automotive use, engineers must select the HE3 or HM3 suffix versions explicitly qualified to AEC-Q101. The P6SMB130CA-E3/5B itself is appropriate for non-safety-critical consumer or industrial applications where automotive qualification is not mandated.
How does the bidirectional nature of the P6SMB130CA-E3/5B affect its PCB layout?
The P6SMB130CA-E3/5B has no polarity marking and functions identically in both directions, simplifying PCB layout for AC-coupled or floating signals like RS-485, CAN, or differential audio. Unlike unidirectional TVS diodes, it requires no orientation verification during placement, reducing SMT programming complexity and eliminating risk of reverse installation. Its symmetric clamping ensures equal protection against positive and negative transients on the same line pair.
What is the thermal resistance from junction to lead (RθJL) for the P6SMB130CA-E3/5B?
The P6SMB130CA-E3/5B has a typical thermal resistance from junction to lead (RθJL) of 20 °C/W, measured under standard test conditions. This low value enables efficient heat transfer from the silicon die to the PCB copper pads, supporting reliable operation at elevated ambient temperatures. When mounted on 0.2" × 0.2" copper pads per the datasheet recommendation, the P6SMB130CA-E3/5B achieves stable thermal performance without additional heatsinking.
Does the P6SMB130CA-E3/5B meet moisture sensitivity level (MSL) requirements for lead-free reflow?
Yes, the P6SMB130CA-E3/5B meets MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. This classification means the device has unlimited floor life and can be subjected to standard lead-free reflow profiles without pre-baking. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102, ensuring robust solderability and whisker resistance in high-reliability manufacturing environments using the P6SMB130CA-E3/5B.
