Product details
Overview
P6SMB16CAHM3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 16 V standoff voltage (VWM), 17.1 V minimum breakdown voltage (VBR), 22.5 V maximum clamping voltage (VC) at 26.7 A peak pulse current (IPPM), and 600 W peak pulse power capability with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB16CAHM3_A/H datasheet, P6SMB16CAHM3_A/H pinout, P6SMB16CAHM3_A/H application, or P6SMB16CAHM3_A/H equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification status, MSL Level 1 moisture sensitivity, halogen-free RoHS compliance, and thermal resistance (RθJA = 100 °C/W) under standard PCB pad layout conditions.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical reverse/forward conduction characteristics due to its bidirectional construction. It responds to transient overvoltages within picoseconds and maintains low incremental surge resistance during 10/1000 μs pulses, enabling effective suppression of inductive switching spikes and ESD events.
The P6SMB16CAHM3_A/H uses a glass-passivated silicon junction and is rated for continuous operation from −65 °C to +150 °C junction temperature. Its thermal design relies on 0.2" × 0.2" copper pads per terminal, delivering RθJL = 20 °C/W and supporting repetitive surge duty cycles up to 0.01%.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 16 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 17.1–18.9 V at 1 mA - Voltage at which device enters avalanche conduction; ensures reliable triggering above normal operating range |
| VC (Clamping Voltage) | 22.5 V at 26.7 A IPPM - Peak voltage seen by protected circuit during worst-case 10/1000 μs transient; determines downstream component stress |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capacity under standardized surge waveform; enables robust protection against IEC 61000-4-5 surges |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard FR-4 with 0.2" × 0.2" copper pads; informs derating above 25 °C ambient |
| TJ max. | +150 °C - Maximum allowable junction temperature; sets upper limit for thermal design and reliability validation |
| MSL Level | Level 1 (per J-STD-020) - No floor life limitation; supports standard reflow without baking preconditioning |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant, AEC-Q101 qualified. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); matte tin-plated terminals solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; common node in bidirectional configuration | Symmetrical terminal - no polarity marking; connects to line being protected (e.g., CAN_H or RS-485 A) |
| Cathode | Current exit point in forward bias; common node in bidirectional configuration | Symmetrical terminal - no polarity marking; connects to same line (e.g., CAN_L or RS-485 B); forms differential clamp pair |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables symmetric transient suppression on AC-coupled or differential lines (e.g., USB D+/D−, RS-485) without polarity concerns |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for ADAS sensor interfaces and body control modules |
| 600 W peak pulse power | Withstands IEC 61000-4-5 Level 4 (4 kV surge) on 2 Ω source impedance when mounted per recommended pad layout |
| Low clamping ratio (VC/VBR ≈ 1.32) | Minimizes overvoltage stress on downstream ICs - critical for 3.3 V or 5 V logic interfacing with unprotected external connectors |
| MSL Level 1 handling | Eliminates pre-reflow baking steps and simplifies SMT line integration in high-volume manufacturing environments |
Applications
| Automotive Sensor Interface Protection | Industrial RS-485 Communication Line |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16CA | Same VWM (16 V), lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 150 °C/W) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 without parallel devices | Select when board space is constrained and surge threat level is ≤2 kV; verify thermal margin at full load |
| 1.5KE16CA | Same VWM (16 V), higher PPPM (1500 W), axial DO-201 package (through-hole, manual assembly) | Not compatible with automated SMT lines; requires wave solder or hand-soldering; larger board area | Choose for prototyping or legacy through-hole designs where 600 W is insufficient and rework tolerance is acceptable |
Compared with P6SMB16CAHM3_A/H, SMAJ16CA trades peak power and thermal performance for compactness, while 1.5KE16CA offers higher surge capacity at the cost of assembly compatibility and modern compliance (no AEC-Q101 or MSL Level 1).

FAQ
What does the "CA" suffix indicate in P6SMB16CAHM3_A/H?
The "CA" suffix in P6SMB16CAHM3_A/H denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression in both polarities - essential for protecting AC-coupled or differential signal lines like RS-485, CAN, or USB without regard to voltage polarity. This differs from unidirectional variants (e.g., P6SMB16A) that require correct cathode orientation.
Is P6SMB16CAHM3_A/H qualified for automotive use?
Yes, P6SMB16CAHM3_A/H is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's P6SMB datasheet (Rev. 09-Jan-2024). It undergoes stress testing for temperature cycling, high-temperature reverse bias, and ESD per automotive reliability standards - making it suitable for under-hood and cabin ECUs.
What is the maximum clamping voltage of P6SMB16CAHM3_A/H at rated peak pulse current?
The maximum clamping voltage (VC) of P6SMB16CAHM3_A/H is 22.5 V at 26.7 A peak pulse current (IPPM), measured under the standard 10/1000 μs waveform. This value defines the highest voltage imposed on protected circuitry during worst-case surge events and is critical for ensuring downstream ICs remain within absolute maximum ratings.
Does P6SMB16CAHM3_A/H require special PCB layout considerations?
Yes, P6SMB16CAHM3_A/H requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve specified thermal performance (RθJA = 100 °C/W) and 600 W pulse power rating. Smaller pads increase thermal resistance and reduce surge handling capability - potentially causing premature failure during repetitive transients.
How does the HM3 suffix differ from E3 or M3 in P6SMB16CAHM3_A/H?
The HM3 suffix in P6SMB16CAHM3_A/H indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification - distinguishing it from E3 (RoHS-compliant commercial grade) and M3 (halogen-free RoHS-compliant commercial grade). The "_A/H" denotes packaging: 7" tape-and-reel, 750 units per reel.
