Product details
Overview
P6SMB100CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal or power lines. It features a 100 V standoff voltage (VWM), 137 V maximum clamping voltage (VC) at 4.4 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB100CAHE3_A/H datasheet, P6SMB100CAHE3_A/H pinout, P6SMB100CAHE3_A/H application, or P6SMB100CAHE3_A/H equivalent, key selection criteria include bidirectional surge protection capability, AEC-Q101 qualification status, SMB (DO-214AA) package compatibility, and clamping performance under repetitive 10/1000 μs transients.
Technical Context
This device operates as a bidirectional avalanche diode, symmetrically clamping positive and negative voltage excursions above its breakdown threshold. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns), enabling effective suppression of ESD, lightning-induced surges, and inductive switching spikes.
The P6SMB100CAHE3_A/H is rated for 150 °C maximum junction temperature and exhibits low incremental surge resistance, delivering consistent clamping behavior across its specified operating range. Its MSL Level 1 rating and matte tin-plated terminals support robust automated assembly and long-term reliability in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 85.5 V - Maximum continuous reverse voltage before conduction begins; defines safe operating margin below clamping onset. |
| VBR (Breakdown Voltage) | 95.0–105 V at 1.0 mA test current - Ensures predictable, repeatable avalanche initiation during transient events. |
| VC (Clamping Voltage) | 137 V at 4.4 A IPPM - Limits peak voltage seen by protected circuitry during 10/1000 μs surge, critical for downstream IC survival. |
| PPPM (Peak Pulse Power) | 600 W - Sustains high-energy transients without failure when mounted per recommended 0.2" × 0.2" copper pads. |
| ID (Reverse Leakage) | ≤1.0 μA at VWM - Minimizes standby power loss and avoids false triggering in low-power sensor or signal-line applications. |
| TJ max. | 150 °C - Supports operation in under-hood automotive and industrial control environments with elevated ambient temperatures. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, humidity testing, and mechanical shock per JESD22 standards. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads. Complies with UL 94 V-0 flammability rating and J-STD-002 solderability requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; symmetrical with cathode in bidirectional operation | No polarity marking required - enables identical placement regardless of signal direction; simplifies PCB layout and reduces assembly errors. |
| Cathode | Current exit terminal in forward bias; symmetrical with anode in bidirectional operation | Terminal symmetry eliminates need for orientation verification during pick-and-place; supports automated handling without vision-based alignment. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Provides symmetrical overvoltage protection on AC-coupled or floating signal lines without requiring external polarity management. |
| 600 W peak pulse power (10/1000 μs) | Handles high-energy transients common in motor drives and relay-controlled systems while maintaining low thermal stress on PCB traces. |
| AEC-Q101 qualified (HE3 suffix) | Meets automotive reliability requirements for engine control units, body electronics, and ADAS sensor interfaces without derating. |
| MSL Level 1, 260 °C reflow compatible | Supports single-pass lead-free reflow assembly without moisture-related popcorning or delamination risks. |
| Glass passivated junction | Ensures stable electrical parameters over time and temperature, reducing drift in clamping voltage across 10+ year service life. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100CA | Same SMB package, 100 V VWM, but lower PPPM (400 W) and higher VC (156 V at 3.8 A) | Limited to lower-energy transients; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification or high-energy surge margin. |
| SMCJ100CA | Higher PPPM (1500 W), larger SMC (DO-214AB) package, same VWM/VC specs | Requires PCB area increase (~3× footprint); suited for primary-level protection in power supplies | Choose when system-level surge immunity requires >600 W clamping capacity and board space permits larger package. |
Compared with SMAJ100CA and SMCJ100CA, the P6SMB100CAHE3_A/H delivers optimal balance of AEC-Q101 compliance, 600 W surge handling, and SMB footprint - making it preferred for space-constrained automotive and industrial modules where qualification and reliability are non-negotiable.

FAQ
What does the "CA" suffix indicate in P6SMB100CAHE3_A/H?
The "CA" suffix denotes a bidirectional configuration: the P6SMB100CAHE3_A/H conducts symmetrically in both polarities, making it suitable for AC signal lines, differential buses, or floating circuits where polarity reversal may occur. Unlike unidirectional variants (e.g., P6SMB100A), it has no cathode marking and provides identical clamping behavior for positive and negative transients.
Is P6SMB100CAHE3_A/H RoHS-compliant and halogen-free?
Yes - the "HE3" suffix confirms P6SMB100CAHE3_A/H is RoHS-compliant per EU Directive 2011/65/EU and meets Vishay's material categorization for commercial-grade, lead-free assembly. It is not halogen-free; for halogen-free compliance, the "HM3" variant (e.g., P6SMB100CAHM3_A/H) must be selected.
What is the maximum clamping voltage of P6SMB100CAHE3_A/H and under what test condition?
The maximum clamping voltage of P6SMB100CAHE3_A/H is 137 V, measured at a peak pulse current (IPPM) of 4.4 A using a standardized 10/1000 μs double-exponential waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events.
Can P6SMB100CAHE3_A/H replace P6SMB100A in a design?
No - P6SMB100CAHE3_A/H is bidirectional, while P6SMB100A is unidirectional. Substituting them requires verifying circuit topology: P6SMB100A includes a cathode band and conducts only in reverse bias, whereas P6SMB100CAHE3_A/H has no polarity marking and clamps both polarities. Direct replacement may cause unintended conduction or inadequate protection.
What does the "_A/H" suffix mean in P6SMB100CAHE3_A/H?
The "_A/H" suffix indicates packaging and revision: "A" is the revision code per Vishay's internal documentation, and "H" denotes 7-inch diameter plastic tape-and-reel delivery (750 units per reel). This matches ordering code P6SMB100CAHE3_A/H shown in Vishay's official ordering information table.
