Product details
Overview
P6SMB13CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 13 V standoff voltage (VWM), 18.2 V clamping voltage (VC) at 33.0 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs). It protects signal lines and power rails in automotive sensor units, industrial I/O modules, and telecom interface circuits against ESD and inductive switching transients.
For engineers reviewing the P6SMB13CAHM3/I datasheet, P6SMB13CAHM3/I pinout, P6SMB13CAHM3/I application, or P6SMB13CAHM3/I equivalent, this device delivers AEC-Q101 qualification, halogen-free RoHS compliance, MSL Level 1 moisture sensitivity, and verified bidirectional clamping performance with low incremental surge resistance and fast response time - critical for robust transient suppression in space-constrained PCB layouts.
Technical Context
The P6SMB13CAHM3/I operates as a bidirectional avalanche diode, symmetrically clamping voltage transients above ±18.2 V while maintaining ≤5.0 μA reverse leakage at 11.1 V (VWM). Its glass-passivated junction ensures stable breakdown behavior under repetitive surge conditions, and its thermal resistance (RθJA = 100 °C/W) supports operation up to +150 °C junction temperature when mounted on 5.0 mm × 5.0 mm copper pads.
Designed for automated SMT assembly, it features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets JESD 201 Class 2 whisker resistance. The absence of polarity marking reflects its bidirectional symmetry - unlike unidirectional variants that use a cathode band.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 11.1 V - maximum continuous reverse working voltage before clamping initiates; defines safe operating margin below breakdown |
| VBR (Breakdown Voltage) | 12.4 V (min) to 13.7 V (max) at 1.0 mA - precise avalanche threshold ensuring predictable turn-on during transients |
| VC (Clamping Voltage) | 18.2 V at 33.0 A IPPM - limits downstream voltage stress during 10/1000 μs surge, protecting 15 V-rated ICs |
| PPPM (Peak Pulse Power) | 600 W - sustains high-energy transients without failure under standard 10/1000 μs waveform at 0.01% duty cycle |
| ID (Reverse Leakage) | ≤5.0 μA at VWM - negligible standby current, avoiding signal integrity degradation or battery drain in always-on systems |
| TJ max | +150 °C - enables deployment in under-hood automotive or high-temperature industrial enclosures |
| Package | SMB (DO-214AA) - 3.94 mm × 2.20 mm footprint with 2.18 mm min. cathode-to-anode distance; optimized for pick-and-place |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 3.94 mm × 2.20 mm × 1.52 mm (L × W × H); terminals are matte tin-plated, solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path (bidirectional) | Provides symmetrical conduction path during positive or negative voltage excursions beyond VBR |
| Cathode | Transient return path (bidirectional) | Electrically identical to anode in CA devices; forms dual-junction structure enabling equal clamping in both polarities |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock testing |
| Halogen-free & RoHS-compliant | Meets EU Directive 2011/65/EU and IPC-1752A material declarations; supports green manufacturing requirements |
| MSL Level 1 (260 °C peak) | Enables standard reflow soldering without pre-baking; eliminates moisture-related popcorning risk |
| 600 W peak pulse power (10/1000 μs) | Handles high-energy surges from relay coil collapse or lightning-induced coupling in industrial fieldbus nodes |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes overvoltage exposure to protected ICs - e.g., clamps 13 V nominal line to only 18.2 V during surge |
Applications
| Automotive Sensor Protection | Industrial PLC Digital Input |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13CA | Same VWM (11.1 V) and VC (18.2 V), but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower-energy transients; less suitable for industrial 24 V input protection requiring 600 W margin | Select when board space is constrained and surge energy is ≤400 W; verify thermal derating at elevated ambient temperatures |
| 1.5KE13CA | Higher PPPM (1500 W), axial-leaded DO-201 package; larger size, manual assembly only; VWM = 11.1 V, VC = 20.0 V | Used in legacy through-hole designs or high-power AC mains protection; incompatible with automated SMT lines | Choose for prototyping or low-volume production where rework tolerance and higher surge margin outweigh SMT compatibility |
Compared with SMAJ13CA and 1.5KE13CA, the P6SMB13CAHM3/I uniquely balances 600 W surge capability, AEC-Q101 qualification, SMB SMT compatibility, and halogen-free compliance - making it optimal for volume automotive and industrial PCBs requiring zero layout change across generations.

FAQ
What does the "CA" suffix indicate in P6SMB13CAHM3/I?
The "CA" suffix in P6SMB13CAHM3/I denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional "A" variants (e.g., P6SMB13A), the CA version has no cathode marking and uses a dual-junction structure - confirmed in Vishay's P6SMB datasheet revision 09-Jan-2024, page 1. This makes P6SMB13CAHM3/I ideal for AC-coupled or differential signal lines where polarity reversal is possible.
Is P6SMB13CAHM3/I suitable for automotive applications?
Yes, P6SMB13CAHM3/I is AEC-Q101 qualified, as indicated by the "HM3" suffix (halogen-free, RoHS-compliant, and automotive-grade). It undergoes rigorous stress testing including temperature cycling, high-temperature operating life, and ESD qualification per AEC standards. The device is explicitly listed in Vishay's ordering table for AEC-Q101 variants (page 3, footnote 1), confirming its suitability for under-hood and chassis-mounted automotive electronics requiring long-term reliability.
What is the clamping voltage of P6SMB13CAHM3/I at its rated peak pulse current?
The clamping voltage (VC) of P6SMB13CAHM3/I is 18.2 V at 33.0 A peak pulse current (IPPM), measured using the standard 10/1000 μs waveform. This value is specified in the Electrical Characteristics table (page 2 of datasheet 88370) and represents the maximum voltage seen across the device during a worst-case transient - critical for ensuring downstream 15 V-rated ICs remain within absolute maximum ratings.
How does the "HM3" suffix differ from "E3" or "M3" in P6SMB13CAHM3/I?
The "HM3" suffix in P6SMB13CAHM3/I indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification - distinct from "E3" (RoHS-compliant commercial grade) and "M3" (halogen-free RoHS-compliant commercial grade). Per Vishay's ordering information (page 3), HM3 parts include additional automotive reliability validation and are marked with "_B" or "_D" revision codes; P6SMB13CAHM3/I uses "I" tape-and-reel packaging (3200 units/reel) for high-volume SMT lines.
What is the thermal resistance of P6SMB13CAHM3/I, and how does it affect PCB layout?
P6SMB13CAHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as stated in the Thermal Characteristics table (page 3). To maintain TJ ≤ 150 °C under 5.0 W steady-state dissipation, designers must ensure adequate copper area and avoid excessive ambient temperature - underscoring the need for the recommended pad layout shown in the package outline (page 5) to achieve rated performance.
