Product details
Overview
P6SMB100CAHE3_B/I 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 and power lines. It features a 100 V standoff voltage (VWM), 113 V minimum breakdown voltage (VBR), 137 V maximum clamping voltage (VC) at 4.4 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in industrial and automotive electronics.
For engineers reviewing the P6SMB100CAHE3_B/I datasheet, P6SMB100CAHE3_B/I pinout, P6SMB100CAHE3_B/I application, or P6SMB100CAHE3_B/I equivalent, key selection criteria include bidirectional clamping performance, AEC-Q101 qualification status, SMB (DO-214AA) package thermal resistance (RθJA = 100 °C/W), and compliance with J-STD-020 MSL level 1 reflow profile up to 260 °C peak.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping behavior in forward and reverse directions. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns), enabling protection against ESD, lightning-induced surges, and inductive switching transients.
The device is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient per Figure 2. With 20 °C/W junction-to-lead thermal resistance (RθJL), it supports reliable power dissipation (5.0 W continuous) when mounted on 5.0 mm × 5.0 mm copper pads per JEDEC standard layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 100 V - Maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown. |
| VBR (Breakdown Voltage) | 113–125 V at 1.0 mA test current - Ensures predictable turn-on threshold during transient events. |
| VC (Clamping Voltage) | 137 V at 4.4 A IPPM - Limits peak voltage seen by protected circuitry under 10/1000 μs surge conditions. |
| PPPM (Peak Pulse Power) | 600 W - Sustains high-energy transients without failure; validated per 10/1000 μs waveform with 0.01% duty cycle. |
| TJ max. | 150 °C - Enables operation in under-hood automotive and industrial environments with elevated ambient temperatures. |
| MSL Level | Level 1 per J-STD-020 - Supports standard reflow soldering without moisture sensitivity concerns. |

Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. No polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Terminal 1 (cathode band side not applicable) | One of two symmetrical terminals; bidirectional conduction means either terminal serves as anode or cathode depending on transient polarity. |
| Cathode | Terminal 2 (opposite end) | Identical to Anode in function; no physical marking distinguishes polarity due to bidirectional design. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity constraints. |

| AEC-Q101 qualification | Validates suitability for automotive powertrain, body control, and ADAS modules requiring long-term field reliability. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., <100 ns rise time), improving protection margin. |
| MSL Level 1 rating | Eliminates bake-out requirement prior to SMT assembly, reducing manufacturing cost and process complexity. |
Applications
| Automotive Sensor Interface Protection | Industrial PLC I/O Module Protection |

IC Role / Device Role / Timing Role: Parallel-connected TVS across motor terminals to absorb inductive kickback energy before it reaches MCU GPIO or driver ICs. Use Value: Extends microcontroller lifetime by limiting transient voltage to ≤137 V, well below typical 16 V absolute maximum ratings of embedded I/O pins. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What does the "CA" suffix indicate in P6SMB100CAHE3_B/I?
The "CA" suffix denotes a bidirectional configuration, meaning P6SMB100CAHE3_B/I provides symmetrical clamping in both polarities - essential for protecting AC-coupled signals, differential buses like CAN, or floating inputs where voltage transients may swing positive or negative relative to ground. This differs from unidirectional "A" variants that clamp only in reverse bias.
Is P6SMB100CAHE3_B/I suitable for automotive applications?
Yes, P6SMB100CAHE3_B/I is AEC-Q101 qualified, as confirmed by its "HE3_B" suffix and Vishay documentation. It has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per AEC-Q101 Rev D, making it appropriate for under-hood and cabin modules in passenger vehicles and commercial vehicles.
What is the maximum clamping voltage of P6SMB100CAHE3_B/I and at what current is it specified?
The maximum clamping voltage (VC) of P6SMB100CAHE3_B/I is 137 V, measured at a peak pulse current (IPPM) of 4.4 A using the standard 10/1000 μs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
How does the SMB (DO-214AA) package of P6SMB100CAHE3_B/I compare thermally to larger packages like SMC?
P6SMB100CAHE3_B/I in SMB (DO-214AA) has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W, versus ~50 °C/W for SMC-packaged equivalents. While SMB offers superior board-space efficiency, it requires careful PCB layout - specifically 5.0 mm × 5.0 mm copper pads per terminal - to achieve rated 600 W pulse power without thermal runaway.
Does P6SMB100CAHE3_B/I require special handling during PCB assembly?
No special handling is required beyond standard SMT practices: P6SMB100CAHE3_B/I is rated MSL Level 1 per J-STD-020, allowing exposure to ambient conditions indefinitely and compatibility with standard lead-free reflow profiles peaking at 260 °C. Its matte tin-plated leads meet J-STD-002 solderability requirements without pre-baking.
