Product details
Overview
P6SMB130CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on signal or power lines. It features a 130 V standoff voltage (VWM), 149 V minimum breakdown voltage (VBR), 219 V maximum clamping voltage at 3.4 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, sensor interfaces, and industrial I/O circuits.
For engineers reviewing the P6SMB130CAHM3/I datasheet, P6SMB130CAHM3/I pinout, P6SMB130CAHM3/I application, or P6SMB130CAHM3/I equivalent, key selection criteria include bidirectional clamping symmetry, low clamping ratio (VC/VBR ≈ 1.47), AEC-Q101 qualification status, halogen-free RoHS compliance, and compatibility with automated SMT assembly on standard PCB pad layouts.
Technical Context
This device operates as a voltage-clamped surge protector: under normal conditions it presents high impedance (>1 MΩ at 111 V), but switches to low-impedance conduction within <1 ns when transient voltage exceeds VBR. Its bidirectional architecture enables symmetric suppression of positive and negative polarity surges without polarity-sensitive placement.
The P6SMB130CAHM3/I uses a glass-passivated silicon junction and is rated for repetitive 10/1000 μs pulses at 0.01% duty cycle. Thermal resistance is 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), with maximum operating junction temperature of +150 °C and storage range from –65 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 111 V - Maximum continuous reverse working voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 149 V min - Voltage at which device begins avalanche conduction at 1 mA test current; ensures reliable triggering above normal line transients. |
| VC (Clamping Voltage) | 219 V max at IPPM = 3.4 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Surge energy handling capacity per IEEE 10/1000 μs waveform; supports robust protection against lightning-induced or inductive-switching spikes. |
| ID (Reverse Leakage) | 1 μA max at VWM - Minimal standby current draw; avoids loading sensitive analog or low-power control circuits. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive or high-ambient industrial environments. |
| Package | SMB (DO-214AA) - Standardized 2-pin surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height; compatible with J-STD-020 MSL Level 1 reflow. |
Pinout & Package
Package: SMB (DO-214AA), bidirectional configuration - no polarity marking; symmetrical terminals function as interchangeable anode/cathode pair depending on transient polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Either terminal serves as anode or cathode depending on instantaneous voltage polarity; no fixed polarity assignment. |
| Terminal 2 | Anode/Cathode (bidirectional) | Paired terminal completing the bidirectional path; identical electrical role to Terminal 1; device functions identically regardless of orientation. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130CA | Same VWM (111 V), slightly higher VC (224 V), lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower-energy surges; less thermal margin in high-ambient or high-duty-cycle scenarios | Select when board space is constrained and surge energy is ≤400 W; verify thermal derating at >75 °C ambient. |
| 1.5KE130CA | Same VWM/VC specs, but axial DO-201 package (through-hole), higher PPPM (1500 W), larger size, no AEC-Q101 qualification | Requires manual or wave soldering; unsuitable for automotive or high-reliability SMT production | Choose only for prototyping or legacy through-hole designs where 1500 W headroom justifies assembly complexity and footprint penalty. |
Compared with SMAJ130CA and 1.5KE130CA, the P6SMB130CAHM3/I uniquely combines AEC-Q101 qualification, halogen-free compliance, SMB SMT compatibility, and 600 W surge rating - making it optimal for volume-manufactured automotive, industrial, and telecom modules requiring zero-polarity assembly and long-term supply stability.

FAQ
What is the clamping voltage of the P6SMB130CAHM3/I at its rated peak pulse current?
The P6SMB130CAHM3/I has a maximum clamping voltage (VC) of 219 V at its rated peak pulse current (IPPM) of 3.4 A, measured using the standard 10/1000 μs double-exponential surge waveform. This value ensures downstream ICs such as microcontrollers or interface transceivers experience limited overvoltage stress during transient events, directly supporting IEC 61000-4-5 compliance testing at Level 3.
Is the P6SMB130CAHM3/I suitable for automotive applications?
Yes, the P6SMB130CAHM3/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction with whisker-resistant matte tin plating. It is explicitly rated for automotive-grade temperature cycling, high-temperature reverse bias, and mechanical shock - making it appropriate for engine control units, body electronics, and ADAS sensor interfaces where reliability under harsh conditions is mandatory.
How does the bidirectional design of the P6SMB130CAHM3/I affect PCB layout?
The P6SMB130CAHM3/I has no polarity marking and functions identically regardless of orientation, simplifying PCB layout and eliminating risk of incorrect placement during automated assembly. Engineers can route it across differential pairs (e.g., RS-485 A/B) or AC-coupled signal paths without directional constraints - reducing design review time and improving first-pass yield in high-volume SMT production.
What is the thermal resistance of the P6SMB130CAHM3/I, and how does it impact power dissipation?
The P6SMB130CAHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W. At 5.0 W steady-state power dissipation, this results in a 500 °C rise above ambient - confirming that the device is intended for transient-only operation. Continuous DC power must remain well below 5.0 W, with actual surge duty cycle limited to 0.01% per datasheet specifications.
Does the P6SMB130CAHM3/I meet any specific flammability or material compliance standards?
Yes, the P6SMB130CAHM3/I uses a molding compound rated UL 94 V-0 for flammability and conforms to RoHS Directive 2011/65/EU and EU REACH Regulation (SVHC-free). The HM3 suffix certifies halogen-free composition (Br < 900 ppm, Cl < 900 ppm, total halogens < 1500 ppm), satisfying stringent environmental requirements for industrial, medical, and consumer electronics sold in regulated markets.
